FORGING MACHINE PROVIDED WITH ECCENTRIC CENTER RING TRANSMITTING SYSTEM CONNECTING ROD TYPE FORGING RAM

摘要

PROBLEM TO BE SOLVED: To constitute a stroke position adjusting device in a forging machine in particular in simple and strong structure. SOLUTION: The forging machine 1 is provided with an eccentic center ring transmitting system connecting rod type forging ram 6 having a bearing body 13 which is reciprocatively guided in a forging box 3 in the radial direction to the eccentric ring shaft axis E and rotatively supported along the eccentric ring 11 to drivingly connect this body with the end part near the eccentric ring, and a connecting rod head 12 having a sliding surface for slidingly cooperating so as not to be relatively turned. The sliding surface 20 in the connecting rod head 12 is formed with a slidingly moving passage G in the vertical direction to the axial directional plane regulated with the eccentric ring shaft axis E and the connecting rod axis P and in the sloping direction to the eccentric ring shaft axis E. The bearing body 13 forming the corresponding inclined surface 21, is disposed so as to be adjustable to shift relatively to a connecting rod type forging ram 6 supported so as to be impossible to move in the eccentric ring shaft axial direction through an adjust-driving device 22.
