Behind the descending punching out workpiece in part of the upper die, the waste material of this workpiece falls in a plurality of bar shaped edges of a knife of described male model down, open fuel tap on the part of the upper die behind the horizontal reset, drive the quick upper punch of the described assembly of having an injection by the oil pressure effect by each piston, each row has an injection and upwards plays the interior die pad of the corresponding bar shaped edge of a knife, and the waste material in this bar shaped edge of a knife is popped up; Close oil-closing valve, each die pad, have an injection assembly and each piston reset by gravity fall.
Said method of the present invention is realized by following a kind of punching out workpiece waste material hydraulic pressure device for ejecting.This device comprises:
Once male model is offered a plurality of bar shaped edges of a knife on this time male model, and the infraoral of each bar shaped edge of a knife is reserved some connecting portions at interval, and this connecting portion is divided into a plurality of long mouthful with the infraoral of this bar shaped edge of a knife, in each bar shaped edge of a knife a die pad is housed;
One lower bolster, the tapping at this lower bolster middle part are installed described male model down;
One has the assembly of having an injection that many rows have an injection, and these many rows have an injection corresponding with a plurality of bar shaped edges of a knife of described male model down; And
One pedestal, be provided with some oil hydraulic cylinders in this pedestal, a piston is installed in each oil hydraulic cylinder, the described assembly of having an injection is fixed on each piston, and described lower bolster is fixed on this pedestal, falls the position after rise at described piston, the head that each row has an injection stretches into the described end opening edge of the bar shaped edge of a knife of the correspondence of male model down, raise-position on described piston, each row has an injection and upwards holds up the interior die pad of the corresponding bar shaped edge of a knife, and the waste material in this bar shaped edge of a knife is ejected.
Wherein, the described assembly of having an injection comprises base plate, have an injection plate and many rows have an injection, and many rows pin holes that pass the plate of having an injection of having an injection are fixed, and the base plate that connects described piston is anchored under the plate of having an injection.
Offer cavity volume in the described pedestal, some oil hydraulic cylinders are positioned at the cavity volume bottom, and oily passage is communicated with some oil hydraulic cylinders, and the oral area of some oil hydraulic cylinders is cylinder cap fixedly, and the described assembly of having an injection is positioned at cavity volume top.
Can be provided with 2-12 the bar shaped edge of a knife on the male model under described, the bar shaped knife edge length is 30-600mm.
The present invention reserves some connecting portions at the end opening of the following male model bar shaped edge of a knife along the interval, the structural strength of male model is improved, not yielding or fracture.
The present invention adopts hydraulic way upwards to discharge waste material, pop up by the waste material that piston drives in the bar shaped edge of a knife that have an injection assembly and die pad will descend male model by the oil pressure effect, because piston is falling the position after rise during the descending punching out workpiece in part of the upper die, mould counterdie when pin pours down male model does not have the upwards resistance that oil pressure causes, punch ram power can reduce, operating efficiency improves, and prolong die life.And tradition is subjected to the resistance that the excellent power glue in part of the lower die makes progress at mould in excellent power glue material returned mode when pin pours male model, must make stamping press bigger, and energy consumption increases.
