Abstract
The invention discloses a fine blanking die. The quality problem that the sheared end face of a workpiece blanked through an existing blanking die is rough is solved. The fine blanking die comprises an upper die base capable of moving vertically. A punch-die is fixed to the bottom of the upper die base. An upper plunger is arranged on the upper portion of the upper die base. The lower end of the upper plunger is fixed to a push rod. The push rod penetrates through the upper die base. The lower end of the push rod is fixed to a gear ring pressing plate. A via hole is formed in the middle of the gear ring pressing plate. The punch-die penetrates through the via hole. A lower die base corresponding to the upper die base is arranged below the upper die base. A top plate and a blanking concave die are sequentially arranged on the upper portion of the lower die base from outside to inside. The blanking concave die is provided with piercing terrace dies. A lower plunger is arranged on the lower portion of the lower die base. A top block is fixed to the upper portion of the lower plunger. Ejector rods are fixed to the upper portion of the top block. The upper ends of the ejector rods are fixed to the lower portion of the top plate.
Description
Technical field
The present invention relates to blanking die technology, be specifically related to a kind of fine blanking die.
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 fine blanking die, to solve the quality problems such as workpiece sheared edge that existing blanking die stamping-out goes out is more coarse.
A kind of fine blanking die in this programme, comprising can the upper bolster of vertical motion, the bottom of upper bolster is fixed with punch-die, upper plug is provided with above upper bolster, lower end and the push rod of upper plug are fixed, push rod is through upper bolster, lower end and the gear ring pressing plate of push rod are fixed, the middle part of gear ring pressing plate has via hole, punch-die is through described via hole, immediately below upper bolster, correspondence is provided with die shoe, die shoe top ecto-entad is provided with top board and blanking die successively, blanking die is provided with piercing punch, the below of die shoe is provided with lower plunger, the top of lower plunger is fixed with jacking block, the top of jacking block is fixed with push rod, the upper end of push rod and the bottom of top board are fixed.
Operation principle of the present invention is as follows: during stamping-out blank, blank is sent to top board and blanking die top, then upper plug drive gear ring pressing plate is descending compresses blank jointly with top board, upper bolster drives that punch-die is descending carries out stamping-out to blank, after stamping-out, upper bolster drives punch-die up, and simultaneously upper plug drives gear ring pressing plate up, drives the blank of blanking die being about under stamping-out to eject finally by lower plunger.
The invention has the advantages that: by upper plug for gear ring pressing plate provides pressure-pad-force, blank compressed with coordinating of top board by gear ring pressing plate reliably, can prevent blank radius vector when punch-die is descending from outwards moving, blank is under the extruding of punch-die, gear ring pressing plate and top board, 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, top board and gear ring pressing plate all have corresponding the first vertical pilot hole, in pilot hole, is equipped with the first guide pillar.First guide pillar coordinates with the first pilot hole, has guide effect to the motion of gear ring pressing plate.
Further, also comprise the backing plate be positioned at below upper bolster, the middle part of backing plate has the centre bore passed through for punch-die, and the bottom of backing plate is provided with stopper slot, the size of stopper slot and the consistent size of gear ring pressing plate.Stopper slot has stroke limit effect to the up of gear ring pressing plate.
Further, have the second vertical pilot hole at the sidepiece of backing plate, upper bolster bottom is provided with the second guide pillar, die shoe has three pilot hole corresponding with the second pilot hole and the second guide pillar position, second guide pillar through the second pilot hole, and can be inserted in the 3rd pilot hole.When upper bolster is descending, to it, there is guide effect with the 3rd coordinating of pilot hole by the second guide pillar.
Further, the periphery being positioned at the second guide pillar in the second pilot hole and the 3rd pilot hole is equipped with spring.Spring is set, when punch-die is descending, there is cushioning effect, prevent the instantaneous impact of punch-die excessive and damage is caused to blank.
