A power tool includes a casing, a cutting unit, a transmission device, and a toggle switch. The casing includes a support portion. The cutting unit is used for cutting a target object and moving between a first position and a second position relative to the support portion. The toggle switch includes at least a third position and a fourth position. When the toggle switch is at the third position, the cutting unit performs a first motion: the cutting unit moves from the second position to the first position. When the toggle switch is at the fourth position, the cutting unit performs a second motion: the cutting unit moves from the first position to the second position. A speed at which the cutting unit performs the second motion is greater than a speed at which the cutting unit performs the first motion.

A blanking machine and a method for blanking a bar or pipe material are provided. The blanking machine includes a blanking assembly and a plurality of driving members. The blanking assembly includes a housing, a plurality of pairs of slide rails, and a plurality of striking blocks. The housing defines a plurality of radially distributed grooves. The pairs of slide rails are respectively installed in the grooves. The striking blocks are respectively slidably installed on the pairs of slide rails. The driving members are configured to respectively drive the striking blocks to reciprocate along the slide rails to strike a material to be processed.

A hand operated cutting tool (200) for pipes or tubes includes a housing (202). The housing (202) defining at least one first opening (204) to receive an object (210) to perform a first cutting action, and a second opening (206) which is adapted to perform a second cutting action. The first opening (204) includes a longitudinal axis (A-A1) and the second opening (206) include a longitudinal axis (X-X′). The longitudinal axis (A-A1) and the longitudinal axis (X-X′) include an angle (Z) therebetween that is unequal to 0 degree. And, one or more cutting blades (208, 502) are operatively coupled to the first opening (204) and the second opening (206). The one or more cutting blades (208) is arranged such that it is performing both the first cutting action and the second cutting action.

A bench pipe threading machine and a threading method are provided. The bench pipe threading machine includes a spindle assembly, a die head assembly, a cutter assembly, a reamer assembly, a lifting handle assembly, and a frame assembly. The spindle assembly, the die head assembly, the cutter assembly, the reamer assembly, and the lifting handle assembly are mounted on the frame assembly. The die head assembly, the cutter assembly, and the reamer assembly are respectively matched with the spindle assembly. The frame assembly includes a frame mechanism and a carriage mechanism that is mounted on the frame mechanism. A transmission mechanism is mounted in the frame mechanism and connected to the spindle assembly. The spindle assembly and the lifting handle assembly are mounted on the frame mechanism. The die head assembly, the cutter assembly, and the reamer assembly are mounted on the carriage mechanism.

A process for producing bearing ring blanks, or gearwheel ring blanks or tubular connection-member blanks, comprises the steps of: •a) providing a steel tube; •b) dividing the tube into a plurality of slugs (30, 30′) each having an axial through cavity; •c) supplying the slugs (30, 30′) to a die assembly (20) of a cold-forming station, the forming station including a punch assembly (10); and •d) subjecting the slugs (30, 30′) to contained forward extrusion through the die assembly (20), wherein the thrust imparted by a pushing member (11) of the punch assembly (10) on a subsequent slug (30′) causes passage of a preceding slug (30) through the die assembly (20), with deformation thereof into a blank (40), while a restraining member (12) of the punch assembly (10) occupies the axial cavity of the subsequent slug (30′) and at least part of the axial cavity of the preceding slug (30).

An apparatus for guiding tube processing devices, in particular planing devices, wherein the apparatus is arranged on an outer circumference of the tube to be processed, wherein the apparatus has at least two bands which extend in parallel.

A kit is disclosed for cutting differing sized pipes internally. The kit includes a pipe cutting apparatus, and a plurality of assemblies. The pipe cutting apparatus includes at least one drive member. The plurality of assemblies, attachable to the pipe cutting apparatus, each include: (1) at least one feed member to extend at least one cutting member against a pipe internally and to retract the at least one cutting member from the pipe internally, the at least one drive member to rotate the at least one cutting member against the pipe internally; or (2) at least one clamping member to secure the pipe cutting apparatus to the pipe internally. Each of the plurality of assemblies differ in size so that differing sized pipes can be cut internally by the pipe cutting apparatus by attaching the appropriately sized assembly to the pipe cutting apparatus.

A tool configured to cut a workpiece includes a tool head which has a receiving contour in which the workpiece is received, and a movable cutting edge with a cutting contour. In the course of a cutting process, the cutting edge passes through the receiving contour. The cutting edge is subjected to the effect of an advancement part and can be moved to such an extent in the cutting direction(s) that it can pass all the way through the workpiece. In an embodiment, a position of the cutting edge reached after the cutting edge has passed all the way through the workpiece, the cutting edge, with removal from the advancement part, can be moved out from the cutting direction(s).

The semi-automatic pipe cutter is an electrically powered pipe cutter. The semi-automatic pipe cutter comprises a pipe cutter wheel, an electric motor, a plurality of wire cleaning brushes, a gearing system, a frame, a left pipe driver, a right pipe driver and a pipe channel.
