ABSTRACT:
A press apparatus having a lower die, an upper die and a lateral pressing cam mechanism adapted to apply a lateral pressure to a work clamped between the upper and lower dies. The lateral pressing cam mechanism includes a slidable cam adapted to be slided towards the clamped work through cooperation with a fixed cam fixed to an actuator. The apparatus has a guide mechanism pivotally secured at its one end to a supporting member extended from the lower die and provided at its other end with a guide portion for locating the work on the lower die. A mutually cooperating cam is provided on the upper portion of the slidable cam and on the central portion of the guide mechanism, so that the guide mechanism is swung from the path of the slidable cam as it is moved towards the work clamped between the two dies.
