The automatic blowing decompressor
Technical field
The utility model relates to a kind of decompressor, relates in particular to a kind of automatic blowing decompressor.
Background technology
Press machine is as a kind of machining equipment commonly used; Have a wide range of applications in field of machining; In press machine automatic blanking, punching course, operating personnel need ceaselessly to take out the leftover pieces after molding mass or the processing from mould, take man-hour then; Also increase operating personnel's load, made operating efficiency lower.
Press machine is when carrying out the punching operation, and after product was gone out, the normal mode of manual work that adopts was taken out product from counterdie.There is potential safety hazard in this operation.The time workman is arranged because of careless manipulation, security incident takes place.In addition, when using press machine punching press miscellaneous goods, the workman takes out product with hand and has difficulties, and takes out product with tweezers mostly, and production efficiency is not high, and has potential safety hazard.If in time product is not taken out, then product does not drop in the hopper easily, causes product overlapping, once more during punching press, makes the mould explosion easily.
Summary of the invention
The utility model provides a kind of automatic blowing decompressor, and its purpose mainly is to solve after product is gone out in the prior art, fails by timely taking-up, in the hopper that falls easily to the greatest extent, causes that product is overlapping, the problem of mould explosion, and enhances productivity simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of automatic blowing decompressor comprises upper bolster; Below upper bolster, be provided with stripper plate; Below stripper plate, be provided with lower bolster, below lower bolster, be provided with lower bolster, below lower bolster, be provided with die shoe; Offer via hole on the said lower bolster, be provided with safety pin in this via hole; Offer blowing groove on the said lower bolster, an end of this blowing groove is communicated with air inlet, and its other end is communicated with via hole on the lower bolster; Said air inlet links to each other with an air blowing pipeline.
Related content in the technique scheme is explained as follows:
1, in the such scheme, corresponding safety pin offers slot to make way on the said stripper plate.
2, in the such scheme, said via hole is two; Corresponding safety pin also is two.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1, owing to the application of the utility model, on the lower mould plate, offers two via holes, and in via hole, place safety pin; On lower bolster, offer blowing groove, safety pin and blowing groove cooperate the effect of blowing product of playing, and conveniently product are blown out counterdie; Prevent that product from dropping in the hopper, cause the overlapping and mould explosion of product, simultaneously; Next product falls into counterdie, carries out the punching press of next product again, does not remove product by hand; Protected personal security, improved production efficiency simultaneously, guaranteed that the continuity of production is carried out.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is an A place enlarged diagram in the accompanying drawing 1;
Accompanying drawing 3 is used the lower bolster structural representation for the utility model;

In the above accompanying drawing: 1, upper bolster; 2, stripper plate; 3, lower bolster; 4, lower bolster; 5, via hole; 6, safety pin; 7, blowing groove; 8, air inlet; 9, slot to make way; 10, die shoe.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment:
Shown in Fig. 1~6, a kind of automatic blowing decompressor comprises upper bolster 1; Below upper bolster 1, be provided with stripper plate 2; Below stripper plate 2, be provided with lower bolster 3, below lower bolster 3, be provided with lower bolster 4, below lower bolster 4, be provided with die shoe 10; Offer via hole 5 on the said lower bolster 3, said via hole 5 is two.Be equipped with safety pin 6 in each via hole 5; Offer blowing groove 7 on the said lower bolster 4, an end of this blowing groove 7 is communicated with air inlet 8, and its other end is communicated with via hole 5 on the lower bolster 3; Said air inlet 8 links to each other with an air blowing pipeline (not shown).Corresponding safety pin 6 offers slot to make way 9 on the said stripper plate 2.
During use, the air blowing pipeline is inserted air inlet 8, when when patrix is descending, accomplishing punching press, product is rushed out; Safety pin 6 cooperates the effect of blowing product of playing with blowing groove 7, conveniently product is blown out lower bolster 3, prevents that product from dropping in the hopper, causes the explosion of the overlapping and mould of product; Simultaneously, next product falls into lower bolster 3, carries out the punching press of next product again, does not remove product by hand; Protected personal security, improved production efficiency simultaneously, guaranteed that the continuity of production is carried out.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
