Description

The portable fine blanking die of punch
Technical field
The present invention relates to the portable fine blanking die of a kind of punch.
Background technology
Stamping-out is a kind of stamping procedure utilizing punch die to make portion of material or process part processing to be separated with another part material, process part processing or waste material, and stamping-out is shearing, blanking, punching, punching lack, jet-bedding, cutting, cutter are cut, trimming, cut the general name of the separation circuits such as tongue, incision, trimming.Stamping-out, except as except getting the raw materials ready, is usually used in directly processing packing ring, bicycle chainwheel, instrument gears, cam, shift fork, instrument face plate, and motor, the silicon steel sheet on electrical equipment, the plug connector etc. in integrated circuit.The stamping-out mode generally adopted at present is that blank is placed in lower cavity die top, and punch is descending directly carries out punching press to blank, namely completes stamping-out after the waste material blanking that stamping-out falls.Often there are some problems in the workpiece of the stamping-out gained adopting this just common: its sheared edge has more coarse fracture belt, and with certain gradient, but also may collapse angle, burr etc. be there is, the workpiece quality processed is poor.
Summary of the invention
The invention is intended to provide a kind of punch portable fine blanking die, to solve the quality problems such as workpiece sheared edge that existing blanking die stamping-out goes out is more coarse.
The portable fine blanking die of punch in this programme, comprise die shoe, die shoe has vertical up big and down small shoulder hole, the ladder of shoulder hole is fixed with backing plate, the top of backing plate is provided with gear ring pressing plate, being provided with in the below of die shoe can the slide block of vertical motion, the top of slide block is arranged with two push rods with the vertical center line of slide block, two push rods are used for applying blanking pressure to punch-die, via hole is had in the middle part of gear ring pressing plate, punch-die is through via hole, upper bolster is positioned at directly over die shoe, the bottom of upper bolster is fixed with the blanking die of ring-type, the top of upper bolster is provided with upper plug, lower end and the push pedal of upper plug are fixed, push pedal and two push rods are fixed, lower end and the upper male mould of push rod are fixed, upper male mould is through blanking die, upper male mould is also provided with piercing punch.
The invention has the advantages that: during work, from side direction, blank is sent into the top of punch-die and gear ring pressing plate, then upper plug drives upper male mould, upper bolster to drive blanking die descending, blank compresses by the pressure-pad-force of gear ring pressing plate and blanking die, and slide block and upper plug move in the same way, drives punch-die and upper male mould to carry out stamping-out to blank simultaneously, after stamping-out, upper plug drives upper male mould up, and upper bolster drives blanking die up, and the blank good by stamping-out and waste material are released.
The invention has the advantages that: by gear ring pressing plate and blanking die to the compression of blank, can prevent blank from outwards moving in footpath when upper male mould is descending, blank is under the extruding of punch-die, gear ring pressing plate and upper male mould, improve the plasticity of material, inhibit the generation of sheared edge crackle, can reduce even to eliminate coarse fracture belt, improve workpiece processing quality.
Further, die shoe is fixed with vertical guide pillar, upper bolster has vertical pilot hole, during matched moulds, guide pillar can be inserted in pilot hole.By guide pillar and pilot hole be engaged in upper bolster move time, it is had to the effect of guiding, makes die-closed position more accurate.
Further, in pilot hole, spring is provided with.Spring is set, when blanking die is descending, there is cushioning effect, prevent the instantaneous impact of blanking die excessive and damage is caused to blank.
Further, be provided with flange on the top of upper male mould, the upper surface of gear ring pressing plate can offset with the lower surface of flange.The motion of flange to blanking die has up stroke position-limiting action.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
