For, the omitting of some known structures and their instructions in the attached drawings are understandable.
Embodiment
As illustrated in fig. 1 and 2, a kind of simple punching die, including punch assemblies 1, cavity plate component 2 and mould rack 3 are provided,
Mould rack 3 includes the second support end for the first support end 31 of anchor membrane module 2 and for installing punch assemblies 1
32, as shown in figure 3, second support end 32 is equipped with through hole 321 pushes punching, punch assemblies 1 and cavity plate component for punch assemblies 1
2 positions are correspondingly arranged, and elastomeric element 4 is additionally provided on second support end 32 and is abutted with punch assemblies 1, elastomeric element 4 can make punch-pin
Component 1 is sprung back after coordinating completion punch operation with cavity plate component 2.
The present embodiment is intended to be punched out operation by the way that simple punched feature is arranged, and the setting of elastomeric element 4 can make convex
Immediately on the one hand rebound can effectively ensure that the safety in utilization of mold to membrane module 1 to be detached with cavity plate component 2, on the other hand
Greatly enhance the punching efficiency of mold.
Mould rack 3 is arranged in open rectangular substructures, and wherein first support end 31 and second support end 32 is located at square
The open end of shape structure.
Specifically, as shown in figure 3, punch assemblies 1 include realizing the movable punch 11 of punch operation, being sheathed on movable punch
The binder portion 12 of 11 peripheries further includes the punch-pin limiting section 13 for being sheathed on 12 periphery of binder portion, and movable punch 11 is far from mold branch
The end of frame 3, which is equipped with limited step 111, prevents binder portion 12 from deviating from, and the end that binder portion 12 is contacted with limited step 111 is equipped with
Limit protrusion 121 contacts to prevent with 13 end face of punch-pin limiting section punch-pin limiting section 13 from deviating from, punch-pin limiting section 13 it is another
End face is abutted with elastomeric element 4.
321 aperture of through hole at second support end is adapted to 12 periphery of binder portion, 1 entirety of punch assemblies and second support end
32 contact form is：12 periphery of binder portion is contacted with 321 internal diameter of through hole, 13 lower face of punch-pin limiting section and elastomeric element 4
Contact.
Elastomeric element 4 selects binder spring in the present embodiment（That is compression spring）, it is the spiral bullet for bearing axial compressive force
Spring, spring contraction deforms when by external applied load, stores deformation energy, and steady rebound occurs when external applied load disappears.
Pressure is uniform when to make external applied load be applied in punch assemblies 1, can be in 111 periphery of limited step of movable punch 11
It is arranged convex mould pad 14, the periphery of convex mould pad 14 is equal with 121 periphery of limit protrusion in binder portion, to make external applied load contact
When movable punch 11 and convex mould pad 14, external applied load pressure is evenly distributed on the end face of movable punch 11 and convex mould pad 14,
So that punch assemblies 1 is steadily pushed, to ensure that punching position is accurate, is unlikely to that bias occurs.
Cavity plate component 2 includes the cavity plate fixed frame 21 being fixedly connected with first support end 31, is equipped in cavity plate fixed frame 21
Non-through through-hole 211 is placed with movable matrix 22, diameter and the movable matrix 22 of non-through through-hole 211 in non-through through-hole 211
Outer diameter adaptation.
Specifically, cavity plate fixed frame 21 can be directly welded at first support end 31, be to better ensure that its position certainly
Degree and the concentricity with punch assemblies, the present embodiment use the providing holes position on first support end 31（It is not shown）, cavity plate fixes
Frame 21 is installed vertically in the position of the hole.
Good drainage loop is formed for ease of punching and blanking, 211 bottom of non-through through-hole is equipped with the oblique cavity plate that is through to and consolidates
Determine the scrap discharge hole 212 of frame periphery, oblique direction of running through is that punching and blanking can be made to be arranged automatically along waste material under the effect of gravity
Portal outside 212 discharge cavity plate fixed frames 21.
The accurate compression of workpiece is positioned to ensure to be formed between binder portion 12 and movable matrix 22 in the present embodiment, is such as schemed
Shown in 2, movable matrix 22 is preferably protruded from into non-through through-hole 211 and is arranged, while covered in 221 periphery of the protruding end of movable matrix
If cavity plate positions backing plate 23, thus, which cooperating between binder portion 12 and movable matrix 22 and cavity plate positioning backing plate 23 will
Workpiece compresses positioning, keeps punching smooth and accurate progress.
Cavity plate, which positions backing plate, can be directed to the size of specific workpiece, by being cut by laser the positioning thin plate of one piece of suitable dimension, set
On the movable matrix of protrusion.
Above-mentioned cavity plate fixed frame 21 of having mentioned is installed vertically in the hole position at first support end 31, it can both be carried out again at this time
It is secondary to be welded and fixed, also cavity plate fixed frame 21 can be made to be secured firmly on first support end 31 otherwise, the present embodiment
In 21 peripheral surface of cavity plate fixed frame is provided with limiting groove 213, cavity plate pressing plate 24, cavity plate are arranged in limiting groove 213
24 one end of pressing plate is arranged in jag, is arranged for circular arc at prong, which is adapted to the periphery of cavity plate fixed frame 21, prong
The fork-tail of both sides is symmetrical arranged relative to prong, and fork-tail is bonded limiting groove setting, the other end of cavity plate pressing plate 24 and first
Frame end 31 is bolted, and so cavity plate fixed frame 21 can be made to be fixedly connected with first support end 31.
To reduce the vibration of punching die in punch process, 3 bottom of mould rack is also associated with die bottom plate 5, mold branch
Frame 3 is bolted with die bottom plate 5, and die bottom plate 5 can provide cushioning effect for mold work, while also can guarantee punching
The installation flatness of mold.
The simple punching die of the present embodiment largely saves laser cutting and mold die sinking expense, punching production site are random
Adjustable, without occupying how much area, and installation and debugging and subsequent maintenance are quite convenient, and production process is on duty convenient for management, employee
Without training, personal safety and equipment safety do not have hidden danger.
Above-mentioned simple punching die is mainly used in the hole to the workpiece punching 4~16 that thickness is 1~4mm, needs root certainly
According to workpiece hole size, the movable punch and movable matrix of the more arbitrary combinations of set of setting in advance specifically need the aperture of punching not
Meanwhile it being realized by replacing movable punch and the movable matrix of different-diameter.
The simple punching die of the present embodiment, which is particularly suitable for burying ironware to automobile, to be punched out.
Obviously, above-described embodiment is only intended to clearly illustrate technical scheme of the present invention example, and is not
Restriction to embodiments of the present invention.For those of ordinary skill in the art, on the basis of the above description also
It can make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all
