Abstract

The invention discloses a convex mold and concave mold self-guide seamless blanking device which comprises a base, a concave mold guide sleeve component, an ejector plate, a convex mold guide column component, an upper body and a flange, wherein the concave mold guide sleeve component is fixed on the base; the ejector plate is arranged in the concave mold guide sleeve component; an elastic body is arranged between the ejector plate and the base; the upper body is arranged on the concave mold guide sleeve component and is fixedly connected with the concave mold guide sleeve component through a screw; the convex mold guide column component is arranged in the upper body; a limiting step is arranged in the upper body; a return spring is arranged between the convex mold guide column component and the limiting step of the upper body; the flange is fixed at the upper end of the upper body through the screw; an air inlet is formed in the center of the flange and is communicated with the central inner hole of the convex mold guide column component; a feeding opening is formed between the upper body and the concave mold guide sleeve component. According to the blanking device, a convex mold acts as a guide column and a concave mold acts as a guide sleeve, so that seamless punching is realized and the mold manufacturing and processing costs are low.

Description

A kind of punch die self-steering gapless blanking apparatus
Technical field
The present invention relates to a kind of mould, specifically a kind of punch die self-steering gapless blanking apparatus.
Background technology
Tradition superthin section fine-edge blanking, generally adopts fine-edge blanking equipment, and it requires high, uses, maintenance cost is high.And blanking die complex structure especially, as shown in Figure 1, its requirement on machining accuracy is high, involves great expense, and the manufacturing cycle is long.
Summary of the invention
The object of the present invention is to provide a kind of punch die self-steering gapless blanking apparatus, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of punch die self-steering gapless blanking apparatus, comprise base, die guide pin bushing component, head part plate, punch guide pillar component, upper body and flange, described die guide pin bushing component is fixed on base, in described die guide pin bushing component, head part plate is installed, between described head part plate and base, elastomer is set, described upper body is arranged on die guide pin bushing component, upper body is fixedly connected with by screw with die guide pin bushing component, punch guide pillar component is set in described upper body, in described upper body, limited step is set, back-moving spring is provided with between described punch guide pillar component and the limited step of upper body, described flange is fixed by screws in the upper end of upper body, described flange center is provided with air inlet, described air inlet is communicated with the central bore of punch guide pillar component, between described upper body and die guide pin bushing component, charging aperture is set.
As the further scheme of the present invention: be provided with the first sealing ring between described punch guide pillar component and upper body.
As the present invention's further scheme: be provided with the second sealing ring between described upper body and flange.
Compared with prior art, the invention has the beneficial effects as follows: the punch of the guide pillar of pilot unit, guide pin bushing and stamping-out unit, die are carried out function fusion by the present invention, namely punch is held concurrently its guide pillar function, die is held concurrently its guide pin bushing function, realize zero clearance stamping-out truly, the sheet member that it is gone out, the burr of ultra-thin plate are little, die manufacturing cost is only 1/10th of traditional fine-edge blanking equipment, because only need compressed air without equipment, its manufacturing cost is only 1/10th of traditional processing charges.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing fine-edge blanking equipment.
Fig. 2 is punch die self-steering gapless blanking apparatus structural representation.
Fig. 3 is the A-A sectional view of Fig. 2 in punch die self-steering gapless blanking apparatus.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 2 ~ 3, in the embodiment of the present invention, a kind of punch die self-steering gapless blanking apparatus, comprise base 1, die guide pin bushing component 2, head part plate 3, punch guide pillar component 4, upper body 5 and flange 6, described die guide pin bushing component 2 is fixed on base 1, in described die guide pin bushing component 2, head part plate 3 is installed, between described head part plate 3 and base 1, elastomer 13 is set, described upper body 5 is arranged on die guide pin bushing component 2, upper body 5 is fixedly connected with by screw with die guide pin bushing component 2, punch guide pillar component 4 is set in described upper body 5, in described upper body 5, limited step 7 is set, back-moving spring 8 is provided with between described punch guide pillar component 4 and the limited step 7 of upper body 5, the first sealing ring 9 is provided with between described punch guide pillar component 4 and upper body 5, described flange 6 is fixed by screws in the upper end of upper body 5, the second sealing ring 10 is provided with between described upper body 5 and flange 6, described flange 6 center is provided with air inlet 11, described air inlet 11 is communicated with the central bore 12 of punch guide pillar component 4, between described upper body 5 and die guide pin bushing component 2, charging aperture 14 is set.
Operation principle of the present invention is: when not working, punch guide pillar component 4 is in upper end position under the effect of back-moving spring 8; During work, first the workpiece of required stamping-out is put into from charging aperture 14, then console switch is passed through, compressed air is filled with through air inlet 11, under compressed-air actuated promotion, punch guide pillar component 4 starts to move downward the concave die cavity stop motion under the effect of limited step 7 that enter die guide pin bushing component 2, and now baric systerm pressure raises and automatic deloading pressure relief; Punch guide pillar component 4 returns upper end position under the effect of back-moving spring 8, and the workpiece swept away then is ejected concave die cavity under the thrust of head part plate 3, takes off workpiece and rim charge, completes a stamping-out circulation.
The punch of the guide pillar of pilot unit, guide pin bushing and stamping-out unit, die are carried out function fusion by the present invention, and namely punch is held concurrently its guide pillar function, and die is held concurrently its guide pin bushing function, realizes zero clearance stamping-out truly.
