Description
Technical field
The present invention relates to metal stamping die field, especially a kind of continuous stamping die that dislocation type control product returns back to top.
Background technology
The progressive die refers to forcing press in a punching stroke, using band-like punching press raw material, is used on a secondary mold
Several different stations are completed at the same time the cold stamping punch die of multi-step forming processes, and mold completes primary, material strip spacing shifting per punching press
It is dynamic primary, until product is completed.
Currently, when this industry of mould punching is for being carried out continuously punch die, stamping die is to need to restore to carry out
Punching press again, common draw forming mode cannot control product and the defect that returns back to top occurs, can cause to produce once returning back to top occurs in product
Product generate unqualified；As shown in Figure 1, stamping die in the prior art is molded after raw material completes punch forming,
I.e. upper die holder 1 drives molding public affairs 2 to move upwards, but the lower stripper 4 on lower die holder 3 also can be under the driving of spring 5 simultaneously
It moves upwards, product returns back to top in order to prevent, therefore needs that a large amount of upper mold spring 6 is arranged on upper die holder 1, and upper mold spring 6 can push away
Product is pressed on lower stripper 4 by dynamic upper molding public affairs 2 moves upwardly together a distance, so as to prevent in upper molding public affairs
During 2 move upwards, lower stripper 4 can drive product to return back to top in upper molding public affairs 2 suddenly, but this scheme, need
A large amount of upper mold spring 6 is set so that mould structure is complicated, also adds the cost of mold, since upper mold spring is more, therefore drives
The public very big stamping press of needs of upper molding, it is more demanding to the entirety of punching machine, the punching machine of big model is needed, enterprise's section is unfavorable for
Save production cost.
Invention content
The object of the present invention is to provide one kind can simplify mould structure, reduce die cost it is low, production cost can also be reduced
The continuous stamping die that returns back to top of dislocation type control product.
To achieve the goals above, the present invention provides the following technical solutions：
A kind of continuous stamping die that dislocation type control product returns back to top, it is characterised in that：Including upper die and lower die, the upper mold
Enter son, the first spring, upper molding public affairs, guide post and jacking block, the first spring one end setting including upper die holder, plate out of supply, de- plate
On upper die holder, the first spring other end is arranged on plate out of supply, and the upper molding public security is mounted in upper die holder bottom, shown
Plate out of supply is mounted on by guide post on upper die holder, and the de- plate enters son and is mounted on de- bottoms, and the jacking block is mounted on de- plate
Enter on son, the lower die includes lower die holder, lower molding public affairs, press plate, material lift plate and the anti-device that returns back to top, the lower molding public security
On lower die holder, the device that returns back to top is separately positioned on press plate both sides, and the both sides of the device that returns back to top are provided with material lift
Plate, the device that returns back to top include movable block, portable pillar, fixed seat, thimble, third spring, the 4th spring and the 5th spring, described
The storage tank moved up and down for movable block, the third spring horizontal setting are offered in fixed seat, and one end is mounted on down
On holding pad, the third spring other end is arranged on movable block, and the portable pillar is mounted on by the 4th spring horizontal and is lived
In motion block, the inclined surface for the protrusion that movable block can be driven to move left and right, the thimble one are set in the storage tank of the fixed seat
Mounted on the bottom of movable block, the thimble other end stretches out fixed seat at end, and the 5th spring one end is mounted on lower die holder,
The other end of the 5th spring other end and thimble abuts against, and the both sides of the press plate are respectively arranged with the knot of L fonts
One end of structure, the portable pillar close to press plate is provided with for " 7 " font with the L font structures cooperation in press plate
Structure.
The bottom of the press plate is provided with several 6th springs, and the 6th spring can drive press plate multiple upwards
Position.
The bottom of the material lift plate is provided with movable guide post and the 7th spring, and the 7th spring can drive material lift plate along living
Dynamic guide post resets upwards.
Beneficial effects of the present invention are：
When work, upper mold moves downward, and public and jacking block is molded in drive and is moved downward, can be driven while jacking block moves downward
The dynamic anti-movable block to return back to top on device moves downward, and while being moved downward due to movable block, fixed seat storage tank is projecting inward
Inclined surface can drive movable block to move downward, to drive the portable pillar on movable block to move downward so that " 7 " in portable pillar
Font structure when the upper molding public affairs of upper mold are by plate stamping stamp, while can drive less than the structure of the L fonts of press plate
Dynamic press plate moves down, and the structure of the L fonts of the press plate can drive portable pillar to the right while moving downward
Movement, after the structure of the L fonts of press plate leaves portable pillar completely, portable pillar is multiple to the left under the action of four springs
Position, to which " 7 " font structure in portable pillar can clasp the structure of the L fonts of press plate, to stop that press plate returns back to top
The shaped article of lower molding Gongshang is ejected at once；When upper mold molds, jacking block can be driven to move upwards, to which movable block is the
It is resetted upwards under the action of five springs, and portable pillar is driven to move upwards, such press plate can also drive shaped article also can
It slowly moves upwards so that it is public that shaped article is separated from lower molding, only when to have left fixed seat storage tank projecting inward for movable block
Inclined surface after, movable block can move right, to drive portable pillar to move right so that " 7 " font structure in portable pillar
It can be detached from the structure of the L fonts of press plate, at this moment press plate can eject shaped article, and upper mold has also resetted upwards
At.
With the above structure, compared with prior art, the present invention haing the following advantages：By the way that the anti-device that returns back to top is arranged,
To reduce the quantity that upper mold spring is arranged on upper die holder, moreover it is possible to which simplified mould structure, reduction die cost is low, can also reduce
Production cost.
