Description
Technical field
The present invention relates to a kind of diel, specifically a kind of blanking flange for Metal buttonses processing is integrally formed
Diel.
Background technology
Button is the life haberdashery that the mankind often keep together.The use value of existing button be more embodied in decoration and
Beautify clothes, burst the aesthetic feeling of its clothes, wherein for Metal buttonses because its is firm, metal-like is preferable, application is more universal.But
The processing of Metal buttonses is needed by steps such as blanking, flange, in process of production, the button of small volume step by step, set up separately
Standby processing, wastes time and energy, processing inconvenience, and cost is high.
The content of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of compact-sized, Metal buttonses can be integrally completed
Blanking, flange, discharging complete button punch forming processing, the blanking flange for reducing production cost is integrally formed diel.
The technical solution adopted by the present invention is：A kind of blanking flange is integrally formed diel, it is characterised in that：The bottom of including

Post, guide spring, die set support column, die set driving rotating disk, rotating disk drive rod, blanking die post, flange mold post
With discharging track, more die set leads are vertically set on base and overcoat guide spring, die set wear be connected on it is more
Include die set bottom plate and stamping die in horizontal crimping guide spring state, the die set on root die set lead
Disk, die set bottom plate are provided with circular counter bore, and punching press mould is that circular configuration is placed in circular counter bore through plane bearing is rotatable
Interior, more than three arcs that punching press mould is provided with circumference uniform distribution strike out type groove, and arc, which strikes out, is symmetrical arranged two in type groove
Chuck, the opposite end of two chucks are provided with the semicircle bayonet socket coincideing in full circumferences, and the phase backside of two chucks is through chuck spring
Push against connection arc and strike out type groove, the upper surface of two chucks is equipped with a folder control hole, and die set bottom plate is provided with corresponding
First arc strikes out the feeding track of type groove, and die set support column upper end is through die set bottom plate through key connection punching press
Mould rotates horizontally state in driving punching press mould, and die set support column bottom is supported on base through bearing, die set
It is in synchronous rotary state that driving rotating disk is socketed on die set support column through one-way clutch, blanking die post, flange mold post
It is arranged at discharging track on base and strikes out the circumference state that two chucks are identical in type groove in corresponding first, second and third arc；
The driving railroad shoe is arranged on base, and driving voussoir is arranged in driving railroad shoe, is driven and is connected actuating arm on voussoir, drives
Swing arm drive connection is arranged on the rotating disk drive rod in die set driving rotating disk；The more drivings pressing plate lead hangs down
It is straight to be arranged on base and overcoat guide spring, driving pressing plate are worn to be connected on more driving pressing plate leads and be oriented in horizontal crimping
Spring state, driving pressing plate are arranged above die set, drive the lower surface of pressing plate convex provided with die holder punching press boss, blanking
Platform, discharging boss and voussoir driving post, blanking boss and discharging boss correspond to first and third arc and strike out type groove respectively, fall
Expect boss lower surface and discharging boss lower surface be equipped with two folder control pins, two folder control pins respectively correspond to first,
The folder control hole that three arcs strike out two chucks in type groove is in push to stretch into a folder of folder control hole driving two with blanking boss
Head strikes out in arc overcomes chuck spring move toward one another two chuck front ends is coincide into full circumferences state in type groove, voussoir drives
The dynamic corresponding abutting driving voussoir in post lower end rises in driving voussoir, decline makes driving voussoir be sent out in driving track by acting force of the spring
Raw displacement or voussoir driving post can continue vertical decline state after dropping to driving voussoir end, correspondingly fall on the driving pressing plate
Material boss, second arc strike out the identical circle center of two chucks in type groove, the position of discharging boss opens up blanking through hole, turned over
Side through hole and unload material through hole, blanking through hole and unload material through hole and be communicated to blanking boss, discharging boss lower surface in opening shape up and down
State.
Further, the voussoir driving post lower end is provided with driving roller, and driving roller pushes against driving voussoir and driven in driving
Dynamic voussoir is in driving track intrinsic displacement state.
Further, the driving pressing plate lower surface is additionally provided with die set boss, drives and corresponds to die set on pressing plate
The position of boss opens up punching press through hole, and it is in upper and lower opening state that punching press through hole, which is communicated to die set boss lower surface,.
The present invention is in use, driving pressing plate is in initial position, and voussoir driving post lower end is in the height of driving voussoir thereon
Position initiating terminal, Metal buttonses material strip strike out type groove feeding on die set bottom plate through corresponding first arc of feeding track,
Punching press pressure head pressure driving pressing plate overcomes the guide spring active force being cased with driving pressing plate lead, voussoir driving post lower end fortune
The low level end for moving driving voussoir drives post lower end to drive voussoir simultaneously by a high position to low level against vertical decline, voussoir is continued
It is subjected to displacement in driving track, driving voussoir drives rotating disk drive rod die set is driven rotating disk through actuating arm thereon
Rotation, the stamped die holder support column of die set driving rotation disc spins drive punching press mould to be revolved on die set bottom plate
