The production method disclosed is a method for producing a front axle beam. The production method includes a die forging step and a bending step. The die forging step is a step of forging a steel material with dies to produce a forged product including a rough web part, which is to be formed into a web part, and four plate-shaped rough flange parts protruding frontward and rearward from an upper side and a lower side of the rough web part, respectively. The bending step is a step of pressing at least one specified rough flange part, which is at least one of the four rough flange parts, with a first die to form a bent portion in the specified rough flange part such that the bent portion is bent inward in an up-down direction of the forged product.

A method of manufacturing a heat sink includes a rib portion forming step of forming a rib portion on a substrate having a flat plate shape in such a manner that a first groove and a second groove are formed on a front surface side of the substrate by plastically deforming the substrate by a press thus forming the rib portion in a region sandwiched between the first groove and the second groove. The method further includes a back surface protruding ridge portion cutting removal step of removing protruding ridge portions formed on a back surface side of the substrate by cutting. The method further includes a fin forming step of forming a plurality of fins by working the rib portion; and a heat sink separating step of obtaining the heat sink by separating a portion within a predetermined range which includes the fins from the substrate.

A collating system for rivets is provided that includes a rivet holder for supporting rivets in a predetermined pattern. In one form, the rivet holder includes a body having cavities for supporting the rivets therein. The rivet holder body includes a top plate member and a bottom plate member. The rivet holder has drive heads connected to the top plate member via frangible portions and the bottom plate member has retaining webs disposed below the drive heads. The top and bottom plates are secured together to capture heads of the rivets between the drive heads and retaining webs. The drive heads may be driven downward to drive the rivet heads from the rivet holder and into bores of a guide block with the retaining webs flexing to release the rivet head from the lower bottom plate member. A method of using the rivet collating system is also disclosed.

The present disclosure provides a method for forging a gear capable of preventing burrs from being formed at an edge of the surface opposite to a direction in which a material in external teeth of the material is pushed. A first exemplary aspect is a method for moving the second punch along a tooth profile groove of the guide die to stack the material and the second punch in this order; and pushing the material and the second punch into a tooth profile groove of the tooth profile die in a stacked state to pass them therethrough, in which a tooth pressing part of the second punch covers at least an edge of a region where external teeth are formed on a surface of the material on the first punch side.

The invention relates to a method (100) for manufacturing a fastening arrangement for fastening a collar to a tube. The method comprises the steps of providing a hollow tube (10), arranging said tube for receiving at least one forming punch (30) in the axial direction of the tube, punching the tube with a forming punch at an inner radial part of an edge portion (16) of the tube in the axial direction of the tube, locally reducing the tube thickness, so that the material being punched is plastically relocated in the axial direction, locally forming a snap portion (11) in the form of a flange (12) in the radial direction towards the hollow inside of the tube, providing a collar (20) configured to be arranged on the tube, wherein the collar comprises at least one receiving portion (21) arranged to receive said snap portion, and arranging the collar to the tube such that the snap portion engages with said receiving portion.

A multi-stage incremental sheet forming system includes a forming tool, and at least one control unit in communication with the forming tool. The at least one control unit is configured to determine a convex hull of a target structure to be formed by the forming tool. The at least one control unit is further configured to operate the forming tool according to a first tool path in relation to an initial structure to form an intermediate structure having a shape based on the convex hull of the target structure. The at least one control unit is further configured to operate the forming tool according to a second tool path in relation to the intermediate structure to form one or more inward features into the intermediate structure to form the target structure.
