METHOD AND DEVICE FOR MANUFACTURE OF CONNECTING ROD

摘要

A device for manufacturing a connecting rod comprises a fixed stage (62) secured onto a base (60), a movable stage (64) so installed as to be move close to and apart from the fixed stage (62), and a set of backup cylinders (153, 155) displacing the overall movable stage (64) along the axial direction of the connecting rod (30). The set of backup cylinders (153, 155) are substantially simultaneously biased to displace a cap part (32) together with the movable stage (64) until the fractured surface of the cap part (32) of the connecting rod abuts on the fractured surface of the rod part (34) of the connecting rod held on the fixed stage (62). Consequently, the removal and release of chips produced on the mating fractured surfaces can be promoted.
