摘要： A base-material hole is formed in a connecting-rod base material. A coating layer is deposited on an inner peripheral surface of the base-material hole. The base-material hole 15 has a cylinder inner-surface portion of a constant inner diameter, formed in a central region in an axial direction, and a tapered inner-surface portion that is continuous with an axially outer side of the cylinder inner-surface portion and is radially enlarged in an axially outward direction. The coating layer has a first coating portion and a second coating portion deposited on the tapered inner-surface portion to adjoin the first coating portion and gradually increasing in material thickness in the axially outward direction.

摘要： A method for manufacturing a connecting rod for an engine contemplates creating a rough connecting rod from high carbon steel. The rough connecting rod is normalized to provide strength and toughness characteristics to the core of the connecting rod for functional operation. A first, second or both ends of the connecting rod are selectively induction hardened to create a durable martensitic structure in those ends. The connecting rod is then cracked and ground to form a final connecting rod for use in internal combustion engines.

摘要： A connecting rod and methods of making a rod are disclosed. A method of making a connecting rod may include the step of providing a connecting rod blank, where the connecting rod blank includes a crankshaft end and a piston pin end. The method may further include forming a crankshaft pin recess in the crankshaft end of the connecting rod blank and a piston pin recess in the piston pin end, and forming at least one lubrication recess in the piston pin end of the connecting rod blank. The lubrication recess and the piston pin recess may both formed concurrently.

摘要： 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.

摘要： A method of operating a forging press having a plurality of tool stages between which workpieces are advanced in succession. Each tool has two identical dies with a center-to-center spacing of half the stroke of a transporter for advancing the workpieces from stage to stage so that in each stage during each forging stroke of the press only one die is in contact with the workpiece while the other die is unused and in the next working stroke, the unused die engages the workpiece and the previously used die is unused. The result is a minimization of the contact time of workpieces with any given die and hence an increase in the life of the dies for a given press output or enhanced output of the press with equal or reduced die wear.

摘要： A process for manufacturing a forged connecting rod of the type including a big end, a shank and a small end. A connecting rod rough forging, free of lateral flash and including at least one bore initiator on the big end and on the small end, is manufactured by forging. The connecting rod rough forging is sized, content-wise, by plating the connecting rod rough forging between two inserts inside a die in order to obtain a sized connecting rod rough forging.

摘要： A flashless metal connecting rod of the type having a one-piece construction and being fracturable into a cap portion and a body portion is produced by providing a precise preform of predetermined dimensions and a precise weight, induction heating the preform to a suitable forging temperature, sequentially compressing the preform between a plurality of unique sets of forging dies. 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.
