ABSTRACT:
A light-weight press for punching, forming, etc., in which the guide pins are bored in order that pull rods may be passed therethrough from actuating cylinders to an adjustment mechanism that interrelates the upper ends of the guide pins with the platen of the press. The adjustment mechanism are connected to each other so as to operate simultaneously and ensure that the forces in the press do not become unbalanced. Downward movement of the platen is limited by striking of the upper ends of the guide pins by stop elements associated with the pull rods.
