DETAILED DESCRIPTION

[0040] With reference to FIG. 1, there is shown one example of a pipe machining apparatus 20 configured to machine pipes P of varying diameters. In some examples, the apparatus 20 completely cuts through pipes P. In other examples, the apparatus 20 prepares an end of a pipe P for coupling to another pipe. In still other examples, the apparatus 20 both completely cuts and prepares a pipe P for coupling to another pipe. In these examples, cutting and/or preparing an end of a pipe P may result in a cut end of the pipe P being cut along a plane generally perpendicular to a longitudinal axis A of the pipe P or cut along a plane transverse to the longitudinal axis A of the pipe P. In some examples, cutting an end of the pipe P along a transverse plane may be referred to as a bevel cut and result in a beveled end of the pipe P. Beveled ends of a pipe may be cut along a wide variety of transverse planes and at a wide variety of angles relative to the longitudinal axis A of the pipe P. In some examples, the beveled ends may be cut along a plane that is traverse to the longitudinal axis A of the pipe at about a 30 degree angle. In other examples, the beveled ends may be cut along a plane that is traverse to the longitudinal axis A of the pipe at about a 37.5 degree angle. These examples of beveled ends, planes and angles are not intended to be limiting upon the present disclosure, but are rather provided to demonstrate at least some of the principles of the present disclosure.

[0041] In the illustrated example, the pipe machining apparatus 20 is formed of two joined-together semicircular sections 24A, 24B and includes a frame 28 and a tool carrier 32. The two sections 24A, 24B together comprise the frame 28 and the tool carrier 32 such that a first portion of the frame 28 and a first portion of the tool carrier 32 are included in one section 24A and a second portion of the frame 28 and a second portion of the tool carrier 32 are included in the other section 24B. In the illustrated example, the frame 28 has a column 36 extending outwardly of the two semicircular sections 24A, 24B and houses a pinion gear configured to couple with a suitable drive motor, such as, for example, an air motor, with suitable gear reduction means. The frame 28 is configured to couple and be fixed relative to a pipe P, and the tool carrier 32 is rotatable relative to the fixed frame 28 and the pipe P. The motor is configured to rotate the tool carrier 32 relative to the frame 28 through a gear train in the column 36.

[0042] The rotatable tool carrier 32 includes one or more tool supports 48 (two tool supports 48 shown in the illustrated example), which support tools 52, 53, 54 for performing cutting or machining operations on the pipe P as the tools 52, 53, 54 rotate circumferentially about the pipe P. The tool supports 48 are coupled to the tool carrier 32 by a plurality of coupling members 50. The machining operation performed by the tool 52 may form a straight edge generally perpendicular to a longitudinal axis A of the pipe P. The tools 53, 54 may form bevels on ends 56, 58 of the two cut pieces P1, P2 of the pipe P that are along planes 60, 62 transverse to the longitudinal axis A of the pipe P. The transverse planes 60, 62 may be at any angle relative to the longitudinal axis A of the pipe P other than ninety degrees. For purposes of demonstrating principles of the present disclosure, the transverse planes 60, 62 will be described as being at about 30 degrees from perpendicularity to the longitudinal axis A of the pipe P or at about 37.5 degrees from perpendicularity to the longitudinal axis A of the pipe P.

[0043] In the illustrated example, the apparatus 20 includes four adjustable clamp members or coupling members 68 engageable with an exterior of the pipe P and having suitable adjustability to couple and concentrically locate the apparatus 20 to the pipe P.

[0044] One or more projections may be adjustably movable into and out of a path of an advancement member 84 coupled to each tool support 48 to advance the tools 52, 53, 54 toward the pipe P. The apparatus 20 may include any number of projections for engaging advancement members 84.

[0045] With continued reference to FIG. 1 and further reference to FIGS. 2 and 3, tools 53 and 54 will be described in further detail. Tool 52 cuts a groove 86 into the pipe P and tools 53, 54 are configured to bevel ends 56, 58 of cut pieces P1, P2 of a pipe P at desired angles. The tool 53 bevels an end 56 of a first cut piece P1 of pipe and tool 54 bevels an end 58 of a second cut piece P2 of pipe. In the illustrated example, the tool support 48 supports both tools 53, 54 for beveling ends 56, 58 of both cut pieces P1, P2 of a pipe. In other examples, the tool support 48 may only support tool 53 for beveling an end 56 of the first cut piece P1 of pipe and the end 58 of the second cut piece P2 of pipe will not be beveled. In further examples, the tool support 48 may only support tool 54 for beveling an end 58 of the second cut piece P2 of pipe and the end 56 of the first cut piece P1 of pipe will not be beveled.

[0046] In the illustrated example, tools 53, 54 cut bevels along planes 60, 62 that are transverse to the longitudinal axis A of the pipe and at about 37.5 degrees from perpendicularity to the longitudinal axis A. Tools 53, 54 may be interchangeable with other tools that cut bevels along planes that are transverse to the longitudinal axis A of the pipe and at different angles from perpendicularity to the longitudinal axis A. For example, as illustrated in dashed lines, tools 53A, 54A may be interchanged with tools 53, 54 and may bevel ends 56, 58 of the two cut pieces P1, P2 of pipe at about 30 degrees from perpendicularity to the longitudinal axis A of the pipe.

[0047] Referring now to FIG. 4, the tool 53A is illustrated and is configured to bevel an end 56 of a first cut piece P1 of the pipe. In some examples, the bevel cut into the end 56 of the first cut piece P1 of pipe may be referred to as an inside bevel and tool 53A may be referred to as an inside bevel tool. In the illustrated example, the tool 53A includes a base 100A and a cutting insert 104 coupled to the base 100A. The cutting insert 104 may be coupled to the base 100A in a variety of manners and all of such manners are intended to be within the spirit and scope of the present disclosure. In the illustrated example, the cutting insert 104 is coupled to the base 100A with two coupling members or fasteners 108. In other examples, the cutting insert 104 may be coupled to the base 100A using any number of fasteners and all of such possibilities are intended to be included in the spirit and scope of the present disclosure. The base 100A defines a projection or lip 112A having an engagement surface 116A that is configured to be engaged by the cutting insert 104. The base 100A also defines coupling apertures 120A therein configured to receive the coupling members 108 therein. Similarly to the alternative examples associated with the coupling members 108, the base 100A may include any number of coupling apertures 120A to correspond to the number of coupling members 108.

[0048] With continued reference to FIG. 4, the cutting insert 104 includes a first cutting edge 124, a second cutting edge 128 positioned opposite the first cutting edge 124, and third and fourth edges 132, 136 opposite each other and between the first and second cutting edges 124, 128. In the illustrated example, the first and second cutting edges 124, 128 are generally parallel to each other and the third and fourth edges 132, 136 are generally parallel to each other. In other examples, the edges of the cutting insert 104 may be oriented differently relative to each other and all of such possibilities are intended to within the spirit and scope of the present disclosure. The cutting insert 104 also defines apertures 140 there through that are alignable with coupling apertures 120A defined in the base 100A. The coupling members 108 are positioned in the aligned apertures 120A, 140 therein to couple the insert 104 to the base 100A. Similarly to the alternative examples associated with the coupling members 108 and coupling apertures 120A of the base 100A, the cutting insert 104 may include any number of apertures 140 to correspond to the number of coupling members 108 and coupling apertures 120A in the base 100A.

[0049] In the illustrated example, the third edge 132 of the cutting insert 104 engages the engagement surface 116A of the base 100A. The lip 112A, the engagement surface 116A, the location of the coupling apertures 120A and the shape of the cutting insert 104 cooperate to ensure the cutting insert 104 is at an appropriate orientation to bevel the end 56 of the first cut piece P1 of the pipe at an appropriate angle α. In the illustrated example, these elements cooperate to ensure the cutting insert 104 bevels the end 56 of the first cut piece P1 of the pipe at about a 30 degree angle (i.e., α=about 30 degrees). The cutting insert 104 may also be rotated 180 degrees to bring the fourth edge 136 of the cutting insert 104 into engagement with the engagement surface 116A of the lip 112A. Again, the lip 112A, the engagement surface 116A, the location of the coupling apertures 120A and the shape of the cutting insert 104 cooperate to ensure the cutting insert 104 is at an appropriate orientation to bevel the end 56 of the first cut piece P1 of the pipe at an appropriate angle α (e.g., α=about 30 degrees). The two cutting edges 124, 128 may provide the cutting insert 104 with additional life compared to a cutting insert that only includes one cutting edge.

[0050] The cutting insert 104 is the portion of the cutting tool 53A that engages, cuts and bevels the pipe P. Thus, the cutting insert 104 may be made of a material appropriate for cutting a pipe P while the base 100A of the cutting tool 53A may be made of a different material. The material from which the cutting insert 104 is made may be more expensive of a material than the material from which the base 100A is made. Typical cutting tools may be made completely of the material required to cut a pipe. Thus, the total cost of the cutting tool 53A may be reduced from past cutting tools made completely of a material required to cut a pipe.

[0051] Referring now to FIG. 5, the tool 53 is illustrated and is configured to bevel an end 56 of a first cut piece P1 of the pipe. Tools 53 and 53A may be interchangeably coupled to the tool support 48 to bevel an end 56 of the first cut piece P1 of the pipe at various angles α or θ. In some examples, the bevel cut into the end 56 of the first cut piece P1 of pipe by the tool 53 may be referred to as an inside bevel and tool 53 may be referred to as an inside bevel tool. In the illustrated example, the tool 53 includes a base 100 and the cutting insert 104 coupled to the base 100. The cutting insert 104 is the same cutting insert 104 that is coupled to the base 100A of the tool 53A. Thus, the cutting insert 104 is configured to be interchangeably coupled to either the base 100A of tool 53A or the base 100 of tool 53. In this manner, only one cutting insert 104 is required to bevel the end 56 of the first cut piece P1 of the pipe at varying angles α, θ and along various transverse planes 60, 60A.

[0052] While the drawings illustrate the cutting insert 104 being configured to couple to two bases 100, 100A, it should be understood that the cutting insert 104 may be coupled to any number of bases in order to bevel an end of a pipe at any number of different angles. In this manner, the present disclosure provides any number of cutting tools to bevel an end of a pipe at any number of angles.

[0053] The cutting insert 104 is coupled to the base 100 of tool 53 in a similar manner to the base 100A of tool 53A since the cutting insert 104 is the same. That is, in the illustrated example, the cutting insert 104 is coupled to the base 100 with the two coupling members or fasteners 108. The same alternative examples described above in connection with coupling the cutting insert 104 to the base 100A of tool 53A also apply to coupling the cutting insert 104 to the base 100 of tool 53 since the cutting insert 104 is coupled similarly to both the base 100A of tool 53A and the base 100 of tool 53. The base 100 of tool 53 also defines a projection or lip 112 having an engagement surface 116 that is configured to be engaged by the cutting insert 104. The base 100 also defines coupling apertures 120 therein configured to receive the coupling members 108 therein.

[0054] With continued reference to FIG. 5, the lip 112, the engagement surface 116, the location of the coupling apertures 120 and the shape of the cutting insert 104 cooperate to ensure the cutting insert 104 is at an appropriate orientation to bevel the end 56 of the first cut piece P1 of the pipe at an appropriate angle θ. In the illustrated example, these elements cooperate to ensure the cutting insert 104 bevels the end 56 of the first cut piece P1 of the pipe at about a 37.5 degree angle (i.e., θ=about 37.5 degrees). The cutting insert 104 may also be rotated 180 degrees to bring the fourth edge 136 of the cutting insert 104 into engagement with the engagement surface 116 of the lip 112. Again, the lip 112, the engagement surface 116, the location of the coupling apertures 120 and the shape of the cutting insert 104 cooperate to ensure the cutting insert 104 is at an appropriate orientation to bevel the end 56 of the first cut piece P1 of the pipe at an appropriate angle θ (e.g., θ=about 37.5 degrees).

[0055] Referring now to FIG. 6, the cutting insert 104 is illustrated in a manner that demonstrates interchangeable coupling of the cutting insert 104 with either the base 100A of tool 53A or the base 100 of cutting tool 53. The elements of the bases 100, 100A and the cutting insert 104 position the cutting insert 104 in the appropriate orientation to bevel the end 56 of the first cut piece P1 of pipe at multiple angles α, θ and along multiple planes 60, 60A transverse to the longitudinal axis A of the pipe P.

[0056] Referring now to FIG. 7, the tool 54A is illustrated and is configured to bevel an end 58 of a second cut piece P2 of the pipe. In some examples, the bevel cut into the end 58 of the second cut piece P2 of pipe may be referred to as an outside bevel and tool 54A may be referred to as an outside bevel tool. In the illustrated example, the tool 54A includes a base 200A and a cutting insert 204 coupled to the base 200A. The cutting insert 204 may be coupled to the base 200A in a variety of manners and all of such manners are intended to be within the spirit and scope of the present disclosure. In the illustrated example, the cutting insert 204 is coupled to the base 200A with two coupling members or fasteners 208. In other examples, the cutting insert 204 may be coupled to the base 200A using any number of fasteners 208 and all of such possibilities are intended to be included in the spirit and scope of the present disclosure. The base 200A defines a projection or lip 212A having an engagement surface 216A that is configured to be engaged by the cutting insert 204. The base 200A also defines coupling apertures 220A therein configured to receive the coupling members 208 therein. Similarly to the alternative examples associated with the coupling members 208, the base 200A may include any number of coupling apertures 220A to correspond to the number of coupling members 208.

[0057] With continued reference to FIG. 7, the cutting insert 204 includes a first cutting edge 224, a second cutting edge 228 positioned opposite the first cutting edge 224, and third and fourth edges 232, 236 opposite each other and between the first and second cutting edges 224, 228. In the illustrated example, the first and second cutting edges 224, 228 are generally parallel to each other and the third and fourth edges 232, 236 are generally parallel to each other. In other examples, the edges of the cutting insert 204 may be oriented differently relative to each other and all of such possibilities are intended to within the spirit and scope of the present disclosure. The cutting insert 204 also defines apertures 240 there through that are alignable with coupling apertures 220A defined in the base 200A. The coupling members 208 are positionable in the aligned apertures 220A, 240 to couple the insert 204 to the base 200A. Similarly to the alternative examples associated with the coupling members 208 and coupling apertures 220A of the base 200A, the cutting insert 204 may include any number of apertures 240 to correspond to the number of coupling members 208 and coupling apertures 220A in the base 200A.

[0058] In the illustrated example, the third edge 232 of the cutting insert 204 engages the engagement surface 216A of the base 200A. The lip 212A, the engagement surface 216A, the location of the coupling apertures 220A and the shape of the cutting insert 204 cooperate to ensure the cutting insert 204 is at an appropriate orientation to bevel the end 58 of the second cut piece P2 of the pipe at an appropriate angle α. In the illustrated example, these elements cooperate to ensure the cutting insert 204 bevels the end 58 of the second cut piece P2 of the pipe at about a 30 degree angle (i.e., α=about 30 degrees). The cutting insert 204 may also be rotated 180 degrees to bring the fourth edge 236 of the cutting insert 204 into engagement with the engagement surface 216A of the lip 212A. Again, the lip 212A, the engagement surface 216A, the location of the coupling apertures 220A and the shape of the cutting insert 204 cooperate to ensure the cutting insert 204 is at an appropriate orientation to bevel the end 58 of the second cut piece P2 of the pipe at an appropriate angle α (e.g., α=about 30 degrees). The two cutting edges 224, 228 may provide the cutting insert with additional life compared to a cutting insert that only includes one cutting edge.

[0059] The cutting insert 204 is the portion of the cutting tool 54A that engages, cuts and bevels the pipe P. Thus, the cutting insert 204 may be made of a material appropriate for cutting a pipe P while the base 200A of the cutting tool 54A may be made of a different material. The material from which the cutting insert 204 is made may be more expensive of a material than the material from which the base 200A is made. Typical cutting tools may be made completely of the material required to cut a pipe. Thus, the total cost of the cutting tool 54A may be reduced from past cutting tools made completely of a material required to cut a pipe P.

[0060] Referring now to FIG. 8, the tool 54 is illustrated and is configured to bevel an end 58 of a second cut piece P2 of the pipe. Tools 54 and 54A may be interchangeably coupled to the tool support 48 to bevel an end 58 of the second cut piece P2 of the pipe at various angles α or θ. In some examples, the bevel cut into the end 58 of the second cut piece P2 of pipe by the tool 54 may be referred to as an outside bevel and tool 54 may be referred to as an outside bevel tool. In the illustrated example, the tool 54 includes a base 200 and the cutting insert 204 coupled to the base 200. The cutting insert 204 is the same cutting insert 204 that is coupled to the base 200A of the tool 54A. Thus, the cutting insert 204 is configured to be interchangeably coupled to either the base 200A of tool 54A or the base 200 of tool 54. In this manner, only one cutting insert 204 is required to bevel the end 58 of the second cut piece P2 of the pipe at varying angles α, θ and along various transverse planes 62, 62A.

[0061] The cutting insert 204 is coupled to the base 200 of tool 54 in a similar manner to the base 200A of tool 54A since the cutting insert 204 is the same. That is, in the illustrated example, the cutting insert 204 is coupled to the base 200 with two coupling members or fasteners 208. The same alternative examples described above in connection with coupling the cutting insert 204 to the base 200A of tool 54A also apply to coupling the cutting insert 204 to the base 200 of tool 54 since the cutting insert 204 is coupled similarly to both the base 200A of tool 54A and the base 200 of tool 54. The base 200 of tool 54 also defines a projection or lip 212 having an engagement surface 216 that is configured to be engaged by the cutting insert 204. The base 200 also defines coupling apertures 220 therein configured to receive the coupling members 208 therein.

[0062] With continued reference to FIG. 8, the lip 212, the engagement surface 216, the location of the coupling apertures 220 and the shape of the cutting insert 204 cooperate to ensure the cutting insert 204 is at an appropriate orientation to bevel the end 58 of the second cut piece P2 of the pipe at an appropriate angle θ. In the illustrated example, these elements cooperate to ensure the cutting insert 204 bevels the end 58 of the second cut piece P2 of the pipe at about a 37.5 degree angle (i.e., θ=about 37.5 degrees). The cutting insert 204 may also be rotated 180 degrees to bring the fourth edge 236 of the cutting insert 204 into engagement with the engagement surface 216 of the lip 212. Again, the lip 212, the engagement surface 216, the location of the coupling apertures 220 and the shape of the cutting insert 204 cooperate to ensure the cutting insert 204 is at an appropriate orientation to bevel the end 58 of the second cut piece P2 of the pipe at an appropriate angle θ (e.g., θ=about 37.5 degrees).

[0063] Referring now to FIG. 9, the cutting insert 204 is illustrated in a manner that demonstrates interchangeable coupling of the cutting insert 204 with either the base 200A of tool 54A or the base 200 of cutting tool 54. The elements of the bases 200, 200A and the cutting insert 204 position the cutting insert 204 in the appropriate orientation to bevel the end 58 of the second cut piece P2 of pipe at multiple angles α, θ and along multiple planes 62, 62A transverse to the longitudinal axis A of the pipe P.

[0064] It should be understood that the use of any orientation or directional terms herein such as, for example, “top”, “bottom”, “front”, “rear”, “back”, “left”, “right”, “side”, etc., is not intended to imply only a single orientation of the item with which it is associated or to limit the present disclosure in any manner.
