Die-height adjusting device of mechanical press

摘要

In a die-height adjusting device of a mechanical press, a slide of the mechanical press is interlockingly connected to a prime mover through a slide actuating mechanism, and an extendible and contractible device for the adjustment of the die-height is provided at the part between the output end portion of the slide and the slide actuating mechanism supported by a frame. The extendible and contractible device is adapted to be adjusted and stopped in the extending and contracting direction thereof by an operating device for the extension and contraction adjustment. Said extendible and contractible device for the adjustment of the die-height comprises an extending and contracting mechanism and a clamp. Said operating device for the extension and contraction adjustment comprises an actuating means for the extending and contracting mechanism and a clamp actuating means. The extending and contracting mechanism is adapted to be actuated extendibly and contractibly by the actuating means for the extending and contracting mechanism. The clamp is adapted to be actuated by the clamp actuating means so as to serve the clamping. And a driven member of the extending and contracting mechanism is adapted to be fixed to a driving member 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.
