Mouthful towards outside lower die, lower die bottom is provided with hair-dryer with respect to the side of discharging channel, and the piston rod of the cylinder is connected with
Mandril, the connecting hole that mandril passes through lower die bottom to open up are connect with backplate bottom.
Preferably, the inlet of the gas channel is threaded with external tracheae.
Preferably, the piston-rod end of the cylinder is welded with ring flange, the mandril is threaded on ring flange.
Preferably, the mandril has several and is annularly uniformly distributed.
Preferably, the lower end of the punch and the tapered shape of the oral area of punching.
Compared with prior art, the beneficial effects of the present invention are：
The configuration of the present invention is simple, reasonable design avoid work by the way that workpiece to be jacked up to the top force effect of mandril on backplate
Make local pressure defective work piece, while after workpiece jack-up, gas channel is passed through gas and the scrap on backplate is blown into punching bottom,
Discharging channel is blown by hair-dryer again, when avoiding two times punch, residual scrap damages workpiece.
