Description

A kind of punching-pressing composite mould
Technical field
It the utility model is related to mould design and manufacture field, and in particular to a kind of punching-pressing composite mould.
Background technology
Punching-pressing composite mould refers to an only station, and forcing press can complete multiple working procedure punching simultaneously under one stroke The mould of sanction.Composite die is significantly structurally characterized in that at least one punch-die part both makees punch-pin, does cavity plate again.
At present, punching-pressing composite mould main Types:
(1) it is punched class compound die such as punching and blanking compound die;Die structure compound die etc.;
(2) shaping class compound die such as bends compound die, compound extruding die;
(3) Blanking Shaping compound die such as blanking and drawing composite die;Piercing-flanging compound die;Drawing trimming compound die;Blanking, Drawing, punching, flange compound die etc..
Utility model content
The technical problem that the utility model solves is to provide a kind of punching-pressing composite mould, can make blanking, bent intermediate, two 4 end bending, middle punching processes are once-combined.Only need one set of die i.e. can be achieved multiple operation it is compound, reach modern science and technology by It is required that high accuracy, high benefit and low cost requirement.
The technical solution that the utility model uses is to provide a kind of punching-pressing composite mould with following structure.Institute Stating mould mainly includes upper bolster, die shoe, forced die shank, rushes circular hole punch-pin, punch-die, cavity plate, lower punch-die and flanging Circle;The forced die shank is arranged at upper bolster center, and be embedded with push rod removable re-packs;The upper bolster is embedded with The guide pillar gap of guide pin bushing and die shoe coordinates;The circular hole punch-pin that rushes is provided with upper padding plate and punch retainer, and in embedded push pedal; The punch-die is fixed by punch-die fixed plate and punch retainer;The cavity plate, bottom plate and lower bolster pass through It is bolted on die shoe.The lower punch-die is fixed by bottom plate and lower bolster, and passes through blank holder centre bore.
Further, the mould uses formal dress composite die.
Further, the mould is oriented to mould bases using the good middle guide pillar of guiding accuracy.
Further, the upper padding plate of the mould, punch retainer and punch-die fixed plate are bolted on mould Seat.
Further, punch-die runs through blank holder under the mould, is fixed by bottom plate and lower bolster.
Further, the mould discharging stock guide and cavity plate are bolted, and cavity plate, bottom plate and lower bolster lead to Cross and be bolted to die shoe.
Further, the mould stripper is made of one with stock guide, and the feeding of plate is controlled using guide pin, is leaned on Automatic feed mechanism compresses.
Further, the mould controls billot into the distance of mould using fixed pin stop.
The beneficial effect of technical solutions of the utility model is:Only need one set of die that blanking, bending and punching can be achieved more Process is compound, reduces process equipment, improves production efficiency, reaches the requirement of high accuracy, high benefit and low cost.
Brief description of the drawings
Fig. 1 is a kind of structural representation of punching-pressing composite mould described in the utility model.
Shown in Fig. 1, each label represents part name:1st, die shoe, 2, guide pillar, 3,8,15,17, bolt, 4, push rod, 5, under Backing plate, 6, bottom plate, 7, cavity plate, 9, discharging stock guide, 10, guide pin bushing, 11, punch-die fixed plate, 12, punch retainer, 13rd, upper padding plate, 14, upper bolster, 16, punch-die, 18, forced die shank, 19, re-pack, 20, rush circular hole punch-pin, 22,24,27, Straight pin, 23, push pedal, 25, lower punch-die, 26, blank holder, 28, play ejection device.
Embodiment
The preferable case study on implementation of the utility model is illustrated with reference to accompanying drawing, the utility model advantage is more readily understood.
A kind of punching-pressing composite mould, including upper bolster 14, die shoe 1, forced die shank 18, rush circular hole punch-pin 20, convex-concave Mould 16, cavity plate 7 and lower punch-die 25;The die shank type of the forced die shank 18 is A types, at the center of upper bolster 14, Be embedded with push rod 21 removable re-packs 19;Match somebody with somebody in the gap of guide pillar 2 of the upper bolster 1 embedded with guide pin bushing 10 and die shoe 1 Close;On the upper padding plate 13 that circular hole punch-pin 20 is rushed by the side of being fixed thereon of punch retainer 12, and the hole of embedded push pedal 23 It is interior;The punch-die 16 is fixed on punch retainer 12 by punch-die fixed plate 11;The cavity plate 7, bottom plate 6 and under Backing plate 5 is bolted on die shoe 1.The lower punch-die 25 is fixed by bottom plate 6 and lower bolster 5, and is passed through The centre bore of blank holder 26.
The upper bolster 14, upper padding plate 13, punch retainer 12 and punch-die fixed plate 11 are sequentially connected from top to bottom, circle Pin 22 realizes guide effect to it.
The cavity plate 7 and discharging stock guide 9 are bolted.
The die shoe 1, lower bolster 5, bottom plate 6 and cavity plate 7 are connected from lower to upper successively by bolt.
The bullet ejection device 28 is bolted on die shoe 1.
Mold work mode described in the utility model:Press ram promotes upper bolster 14 to move downward by die shank 18, Punch-die 16 contacts the billot blank being placed between discharging stock guide 9 and cavity plate 7 first, continues motion forward and completes blanking work Sequence;Upper bolster 14 drives punch-die 16 to continue traveling downwardly, and push pedal 23 and lower punch-die 25 carry out bent intermediate, punch-die 16 to blank Blank holding is subjected to bending two ends with blank holder 26;Upper bolster 14 continues traveling downwardly, and rushes the contact blank of circular hole punch-pin 20 and is rushed Hole.When backhaul molds, press ram drives upper bolster 14 to move upwards, and punch-die 16 first travels upward and out workpiece, simultaneously Elastic device 28 promotes blank holder 26 workpiece is departed from lower punch-die 25;Upper bolster continues up, the workpiece disengaging He of punch-die 16 Push pedal 23.
The beneficial effects of the utility model are:Punch-die and cavity plate can realize blanking process in technical scheme;Punch-die, Lower punch-die, blank holder and push pedal can realize bent intermediate and both sides bending operation;Rushing circular hole punch-pin and lower punch-die can realize Punching operation.The utility model only needs one set of die that blanking, bending and punching multistage manufacturing processes can be achieved, and can increase substantially Production efficiency, reach the requirement of high accuracy, high benefit and low cost.
