Die-height adjusting device of mechanical press

摘要

In a die-height adjusting device for a mechanical press, a slide (4) of the mechanical press (1) is interlockingly connected to a prime mover (9) through a slide actuating mechanism (8) and an extendible and contractible device (18) for the adjustment of the die-height (h) is provided at the part between the output end portion (17) of the slide and the slide actuating mechanism supported by a frame (2). The extendible and contractible device is adapted to be adjusted and stopped in the extending and contracting direction thereof by an operating device (19) for the extension and contraction adjustment. Said extendible and contractible device comprises an extending and contracting mechanism (30) and a clamp (31). A driven member (B) of the extending and contracting mechanism is adapted to be fixed to a driving member (A) thereof by the clamp so as to prevent a relative loose movement therebetween in the extending and contracting direction in a state in which the clamp is actuated to the clamping position by the clamp actuating means.
