Abstract: A presently-preferred process for manufacturing a connecting rod comprises placing a heated preform suitable for being formed into the connecting rod into a closed forge die, and forging the preform in a first forging operation while the preform is at a forging temperature to form an as-forged connecting rod having vertical flash extending therefrom. The presently-preferred process further comprises placing the as-forged connecting rod in a second forge die while the as-forged connecting rod is at a temperature substantially equal to the forging temperature, and forging the vertical flash in a second forging operation. The presently-preferred process also comprises removing the as-forged connecting rod from the second forge die, and machining the as-forged connecting rod to predetermined dimensions.

Abstract: A method for forging a rack bar from a blank pipe. Prior to the rack forging process, a blank pipe is subjected to a process for obtaining an adjustment of a cross-sectional shape of the blank pipe. Such a preliminary adjustment is constructed by a swaging process for reducing an outer diameter of the blank pipe and a ironing process for obtaining a desired irregular cross-sectional shape of the blank pipe. The ironing process is such that locally thickened wall portions are obtained at length wise ends as well as tooth width ends of a rack forging die.

Abstract: A yoke of a universal joint is substantially U-shaped and includes a base portion and first and second arm portions. A method of producing the yoke includes the sequential steps of: (a) shearing a metal plate which is rectangular in shape and has certain uniform width and thickness so as to form a blank which is rectangular in shape and consists of a middle portion and first and second end portions; (b) squeezing the middle portion of the blank by cold forging so that the middle portion is expanded to have first and second peripheral bulge portions which are opposed to each other and that the expanded middle portion becoming substantially oval in shape and thinner than the first and second end portions in thickness; and (c) pressing the blank with a press machine to produce the yoke so that the expanded middle portion and the first and second end portions of the blank are turned into the base portion and the first and second arm portions of the yoke, respectively. According to the method, the amount of waste steel is substantially reduced. The yoke is light in weight and improved in strength.

Abstract: A method of manufacturing a steering rack for a vehicle rack and pinion steering system. The rack comprises gear teeth and a shank that has a constant outside diameter and constant wall thickness over the majority of its length. The method comprises performing a forging operation on a tubular member with an elongate member positioned in the bore of a thickened region of the tubular member. The forging operation forms the gear teeth on the thickened region, and the elongate member is retained within the tubular member. The tubular member is made by performing a forming operation on a length of tube stock such that the outside diameter of the thickened region is smaller than the outside diameter of the shank, and the wall thickness of the thickened region is larger than the wall thickness of the shank.

Abstract: In relation to a rocker arm obtained by applying cold forging to a blank made from a metal wire rod, cold forging is applied to a blank obtained by cutting a metal wire rod to a predetermined length to make a second intermediate blank 34b having a pair of side wall sections 2a and a base 39 which connects the two side walls 2a at one of their respective widthwise edges. Punching is applied to the base 39 of this second intermediate blank 34b to form a first and a second connection sections. In the case where it is assumed that a roller 35 is arranged at a position corresponding to an arrangement position of the roller 35 of the rocker arm to be obtained, on the inside of the second intermediate blank 34b which is to be subjected to punch processing, the roller 35 and the base 39 do not interfere with each other. As a result, performance improvement of an engine fitted with this rocker arm is obtained.

Abstract: A method for producing a press in contact having a press-fitting portion having a U-shaped or V-shaped groove in cross-section to be press-fitted in a cylindrical through-hole of a printed circuit board. A block element having a rectangular cross-section corresponding to the press-fitting portion of the contact is formed at its center with a concaved portion by forging. Both the ends of the forged block element are removed by punching. Thereafter, the remaining U-shaped or V-shaped press-fitting portion in cross-section is further so worked by press working that its outer periphery is formed into arcs which are concentric to the through-hole when the press-fitting portion has been press-fitted and fixed therein.
