Description
Technical field
The utility model relates to a kind of machined die, particularly a kind of lower mold assemblies of blanking and punching mould.
Background technology
Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out the processing and forming such as punching, trimming, bending and drawing.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture.Usually need in punch process trimming after material strip punching, use existing mould need first in blanking die by workpiece blanking, then put into perforating die punching, such operation is many, production efficiency is low, and workpiece needs resetting in addition, have impact on precision and the quality of product.
Therefore, be badly in need of a kind of blanking and punching that simultaneously can realize workpiece of exploitation, make workpiece can automatic ejection, reduce operation, the lower mold assemblies of the blanking and punching mould of enhancing productivity.
Summary of the invention
In view of this, the purpose of this utility model is the lower mold assemblies providing a kind of blanking and punching mould, can realize blanking and the punching of workpiece simultaneously, makes workpiece can automatic ejection, reduces operation, enhances productivity.
The lower mold assemblies of blanking and punching mould of the present utility model, comprise die pad, punch-die, die shoe, described die pad is slidably placed on outside punch-die, elastic rubber and stop screw is provided with between this die pad bottom surface and die shoe end face, described elastic rubber is placed on stop screw outside, described punch-die is supported in die shoe end face by punch-die fixed head and counterdie backing plate, described punch-die top is provided with the punching nibs coordinated with knockout rod, punch-die bottom is provided with the relief hole I be communicated with punching nibs, described counterdie backing plate is provided with the relief hole II be communicated with relief hole I, described die shoe is provided with the relief hole III be communicated with relief hole II, described relief hole I is the reaming that aperture increases from top to bottom gradually, this relief hole I small end is communicated with punching nibs, large end is communicated with relief hole II.
Further, described punching nibs, relief hole II and relief hole III are straight hole, the diameter of described punching nibs and the equal diameters of relief hole I small end, the diameter of relief hole II and relief hole III and the equal diameters of the large end of relief hole I.
The beneficial effects of the utility model: the lower mold assemblies of blanking and punching mould of the present utility model, can realize blanking and the punching of workpiece simultaneously, make workpiece can automatic ejection, reduce operation, enhance productivity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: the lower mold assemblies of the blanking and punching mould of the present embodiment, comprise die pad 1, punch-die 2, die shoe 3, described die pad 1 is slidably placed on outside punch-die 2, punch forming to workpiece is completed for coordinating die, and can be used for after work pieces process completes, it upwards being ejected, be convenient to workpiece take out, improve production efficiency, elastic rubber 4 and stop screw 5 is provided with between this die pad 1 bottom surface and die shoe 3 end face, it is outside that described elastic rubber 4 is placed on stop screw 5, elastic rubber 4 is between die pad 1 bottom surface and punch-die fixed head 6 end face, elastic rubber 4 is for providing elastic force upwards for die pad 1, make die pad 1 can by Work-sheet pressing in die bottom surface, stop screw 5 is spacing for carrying out upper cunning to die pad 1, described punch-die 2 is supported in die shoe 3 end face by punch-die fixed head 6 and counterdie backing plate 7, punch-die 2 is fixed in punch-die fixed head 6, positioned by punch-die fixed head 6 pairs of punch-dies 2, counterdie backing plate 7 weares and teares for preventing die shoe 3 and punch-die fixed head 6, extend the service life of die shoe 3 and punch-die fixed head 6, described punch-die 2 top is provided with the punching nibs 8 coordinated with knockout rod, knockout rod is enable to insert in punching nibs 8, realize the punching processing of workpiece, punch-die 2 bottom is provided with the relief hole I9 be communicated with punching nibs 8, described counterdie backing plate 7 is provided with the relief hole II10 be communicated with relief hole I9, described die shoe 3 is provided with the relief hole III11 be communicated with relief hole II10, by arranging relief hole I9, relief hole II10, relief hole III11, facilitate the discharge of waste material in punching nibs 8, to avoid causing punching nibs 8 to block, impact uses, described relief hole I9 is the reaming that aperture increases from top to bottom gradually, this relief hole I9 small end is communicated with punching nibs 8, large end is communicated with relief hole II10, more be convenient to waste material discharge.
In the present embodiment, described punching nibs 8, relief hole II10 and relief hole III11 are straight hole, the diameter of described punching nibs 8 and the equal diameters of relief hole I9 small end, the diameter of relief hole II10 and relief hole III11 and the equal diameters of the large end of relief hole I9, better can improve waste material and discharge effect.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
