Profiling station, profiling unit formed therefrom and profiling system
A profiling station, a profiling unit formed therefrom and also a profiling installation continuously form a material strip into a profile. The profiling station includes a rack frame, a profiling arrangement with a forming roller and also a first and a second counter roller as well as a drive assembly. A first roller axis and a second roller axis of the counter rollers form between them a buckling angle, wherein the counter rollers define a bending edge for the material strip to be formed. The first counter roller and also the second counter roller are driven by the drive assembly in such a way that the first counter roller has a circumferential speed at its outer circumference and the second counter roller has a circumferential speed at its outer circumference that are equal to one another.
Method of producing shaped article, tooling, and tubular shaped article
A method of production of a shaped article able to suppress occurrence of shaping defects, that is, a method of production of a shaped article including a first step of press-forming a metal plate (1a) into a U-shape to obtain a U-shaped article (1b) having a bottom part (2) straight extending in a longitudinal direction and a second step of press-forming the U-shaped article (1b) to bend it in the longitudinal direction so that the bottom part (2) of the part projects to the inside and obtain a U-cross-section bent article (1c).
Electrical dust filter manufacturing method and electrical dust filter manufactured thereby
Provided is an electrical dust-collecting filter manufacturing method and an electrical dust-collecting filter. The method includes the steps of: preparing a frame body, a dust-collecting electrode, a discharge electrode, and a discharge frame; assembling the dust-collecting electrode into an assembly hole of the frame body; connecting the discharge frame to the frame body via an insulating member; and arranging the discharge electrode in an axial direction inside the dust-collecting electrode via the discharge frame and fixing the same. The dust-collecting electrode assembling step includes: temporarily elastically deforming the dust-collecting electrode in the radial direction and inserting the same into the assembly hole of the frame body; and pressurizing end parts of both ends of the dust collecting electrode, which protrude out of a plate member when fitted into the assembly hole, in the axial direction such that the end parts are compressed against the surface of the plate member.
SQUARE TUBE FORMING METHOD AND SQUARE TUBE FORMING DEVICE
To enhance forming performance enhanced in square tube forming of forming a round tube into a square tube by passing the round tube through a plurality of roll stands arranged in a raw tube forming direction. To give a high degree of multi-usability to a square tube forming device. To suppress the entire length of a roll stand array. A first flat roll stand 20A and a second flat roll stand 20B of rolling directions orthogonal to each other are arranged alternately in a forming direction to form a roll stand array 10. Each of the roll stands 20A and 20B includes roll gap adjusting means by which a rolling amount is independently settable, and one of the first flat roll stand 20A and the second flat roll stand 20B adjacent to each other is driven to rotate by roll driving means 40. A forming rolling amount distribution is allocated individually as a rolling amount at each of the roll stands 20A and 20B. The forming rolling amount distribution is determined in advance for stands from a first-stage stand to a final-stage stand in response to the outer diameter, thickness, and material of a forming target raw tube and an intended dimension of a square tube as a product.
BEAM ASSEMBLY WITH MULTI-HOLLOW FORMATION
A beam assembly includes a first beam that has a first tubular portion and a first projecting portion that extends from the first tubular portion. A second beam has a second tubular portion and a second projecting portion that extends from the second tubular portion. The elongated interior of the first tubular portion defines a first hollow area and the elongated interior of the second tubular portion defines a second hollow area. The first beam is attached to the second beam with the first projecting portion attached to the second tubular portion and the second projecting portion attached to the first tubular portion to define a third hollow area between the first and second projecting portions.
Tubular component with an extruded profile
The disclosure relates to a tubular component for a chassis of a vehicle, wherein the tubular component may include an extruded profile made of an aluminum alloy. The extruded profile may include a rounded extruded profile base and profile walls extending from the rounded extruded profile base and facing one another, wherein the profile walls are curved towards one another to form the tubular component.
Process for the production of thin-walled hollow profiles which are composed of nonferrous metals and have small diameters
A process for the continuous production of thin-walled, radially closed hollow profiles which are composed of nonferrous metals and have a small cross section comprises supply of a flat strip of the nonferrous metal to a forming apparatus (212) at a first supply speed. The thickness of the strip corresponds to the wall thickness of the hollow profile. The forming apparatus (212) is configured for continuous forming of the flat strip supplied into a shape corresponding to the hollow profile. After forming, two opposite edges of the flat strip rest flush against one another in a contact region. A welding apparatus (216) continuously welds the edges which rest flush against one another by means of a laser which emits light having a wavelength of less than 600 nm. The laser heats a point in a welding region which has a diameter which is less than 20% of the cross-sectional dimension of the hollow profile. The welded hollow profile is taken off from the welding region and taken up in an uptake device (226).
