| A forging apparatus 1A includes a swaging apparatus 2 equipped with a fixing die 10, a guide 20 having an insertion passage 22 for inserting and holding a bar-shaped raw material 5 in a buckling preventing state, and a punch 30. The raw material 5 is fixed to the fixing die 10 with the one end portion of the raw material protruded. The one end portion of the raw material 5 is inserted into the insertion passage 22 of the guide 20. Thereafter, while pressing the raw material 5 with the punch 30 in the axial direction, in a state in which an entire peripheral surface of the exposed portion 8 of the raw material 5 exposed between the guide 20 and the fixing die 10 is not restrained, the guide 20 is moved in a direction opposite to the moving direction of the punch 30 so that a length of the exposed portion 8 of the raw material 5 becomes a buckling limit length or less at a cross-sectional area of the exposed portion 8 of the raw material 5. Thus, the one end portion of the raw material 5 is subjected to swaging processing. | ||||||

| A first-stage intermediate formed body (60) is forged by applying pressure in one direction to a working material (41) made of an aluminum alloy. The first-stage intermediate formed body (60) has a tubular arm portion (21), a generally spherical first head portion (62) provided at one end of the arm portion (21), and a ledge portion (63) at the other end of the arm portion (21). A second-stage intermediate formed body (67) is formed by deforming the ledge portion (63) by upsetting. The arm portion (21) of the second-stage intermediate formed body (67) has a second head portion (66) and an axial hole (21a). The second head portion (66) has a rounded shape and is located at the aforementioned other end of the arm portion (21). The axial hole (21a) is formed in the arm portion (21). Pressure is then applied to the first head portion (62) and the second head portion (66) in such a direction as to intersect the axis of the arm portion (21), thereby forming a cylindrical body portion (23) and an outer tube portion (22). Thus, a suspension arm (2) is formed. The invention enables the improvement of the manufacturability and facilitates strengthening of the suspension arm through reduction of the number of parts. | ||||||

| 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. | ||||||

The resulting final forging is both flashless and burrless. Preferably, the sequential compressing of the preform is accomplished through three sets of forging dies which progressively form the precision preform to its ultimate shape. | ||||||

| After a connecting rod for an engine is formed, it is broken or fractured at a fracture point to allow the connecting rod to assemble around a portion of a crankshaft. However, before fracturing the connecting rod, the connecting rod is provided with a layer of paint across the eventual fracture point such that when the connecting rod is fractured the paint extends across both sides of the fracture point. Also before fracturing the connecting rod, serial numbers or symbols are etched into the paint on either side of the eventual fracture point. These serial numbers are unique to that connecting rod, and have similar indicia on either side of the connecting rod. The combination of the paint and serial numbers increase the ability of an assembly worker to assure matching parts of an original connecting rod are re-attached during assembly about the crankshaft. | ||||||
