The shape has a ratio of the lateral length of a projection profile of the forging material as viewed in the direction perpendicular to the direction of pressure application to a length of the forging material as measured in the direction of pressure application is 1 or less. The forged product obtained is a preform of an upper arm or a lower arm with a plurality of branches that is a suspension part for a vehicle or a yoke with a plurality of branches that is a joint part employed in a vehicle suspension. The preform or yoke has metal flow lines along each branch and exhibits enhanced mechanical strength.

A method for producing a metal forged product having a plurality of branches includes a preliminary forging step of forming a preform by closed forging from a cylindrical material (301) having a surface layer (302) on a circumferential surface thereof such that the surface layer is contained in a surface region of the preform; an intermediate forging step of subjecting the preform to forging to thereby extrude the surface layer in the form of flash outside a periphery of a forged product corresponding to a target product; a final forging step of forging the forged product into a product assuming a target product shape; and a flash removal step of removing the flash containing the surface layer from the product assuming a target product shape to thereby produce a target forged product. The forged product is enhanced in mechanical characteristics and has no flash removal mark. Since the cylindrical material having a surface layer on a circumferential surface thereof is used, the power required for the steps can be reduced to enhance the yield of the products on the basis of the forging material.

187 Selectively cold worked hydraulic motor/pump shoe US09896261 2001-06-29 US06802916B2 2004-10-12 Richard G. Rateick, Jr.; Larry A. Portolese
A method of manufacturing a wear resistant shoe (26) includes upsetting (46) one end portion (38) of cylindrical member to work harden that portion to a substantial depth, machining (48) the cylindrical member portion to finished dimensions and surface hardening (56) a face (28 or 34) of the machined cylindrical member portion. The cylindrical member may comprise rod stock of a diameter less than the greatest diameter of the finished shoe and be upset or swaged to axially reduce and radially increase the dimensions of the one end portion. A hollow region (30) is formed in an opposite rod stock end portion and the periphery (50) of the hollow region is crimped about a rounded end (18) of the piston (20). The cold work done during the swaging or forming process provides a foundation for hardened faces comprising balance (28) and auxiliary balance (34) lands, forms a crude shape of the shoe, and imparts work hardening and wear property improvements. The harder metal surface provides a foundation for subsequent surface hardening such as coating with TiN. The crimping process used to join the shoe to the piston imparts cold work to the skirt region of the shoe and enhances the wear resistance of the shoe. The cold heading step (46) may be omitted if a hardened rod stock is used, but the skirt should be annealed (66) prior to crimping to the piston.

190 Method for producing suspension parts of aluminum alloy US09972940 2001-10-10 US06678574B2 2004-01-13 Takumi Fujii; Koji Takeuchi; Hiroyuki Tsutsumi; Yoshiya Inagaki; Atumi Fukuda
A method for producing suspension parts via preforming the workpiece by roll forming. The sectional area and length of the workpiece are calculated. In the former step, more than one orthogonal cross-section is acquired from the suspension part of aluminum alloy, and the sectional area is converted into the area of a circle. An imaginary area is calculated by adding to the converted area an adequate amount of flash. In the latter step, a circular truncated cone is defined from two adjacent imaginary circles and the length of the imaginary center line between the two adjacent imaginary circles. A solid of revolution is defined by connecting these circular truncated cones, and the volume of the suspension part of aluminum alloy is substituted by the volume of the solid of revolution. The value obtained by dividing the sectional area of the workpiece by the volume is regarded as the-length of the workpiece.

A method for determining the dimensions of the workpiece that can be roll-formed for preforming. A method for producing suspension parts via preforming the workpiece by roll forming. The sectional area and length of the workpiece are calculated in steps S215 and S216, respectively. In the former step, more than one orthogonal cross-section is acquired from the suspension part 7 of aluminum alloy, and the sectional area is converted into the area of a circle. An imaginary area is calculated by adding to the converted area an adequate amount of flash. The maximum value of the imaginary area is regarded as the sectional area of the workpiece. In the latter step, a circular truncated cone is defined from two adjacent imaginary circles and the length of the imaginary center line between the two adjacent imaginary circles. A solid of revolution is defined by connecting these circular truncated cones, and the volume of the suspension part of aluminum alloy is substituted by the volume of the solid of revolution. The value obtained by dividing the sectional area of the workpiece by the volume is regarded as the length of the workpiece.

A grease fitting is made by forming its outer shell in a series of cold forging steps to make a blank with the necessary thread blank at one end, a hexagonal center portion, and with a grease-fitting-mating nipple outline at the other end. Threads are rolled onto the thread blank, and the grease-gun-mating nipple is rolled to smooth and burnish its surface. The grease fitting is then successively drilled to make a hole of three different diameters to form the one-way valve ball seat and two ball spring clearance diameters. The ball and spring are inserted, and the end of the hole is formed over the end of the spring to capture the spring into place.
