Abstract
The utility model discloses a kind of blanking die, include upper and lower template, lower bolster is installed with concave-convex mold fixed head, concave-convex mold fixed head is installed with concave-convex mold, the top of concave-convex mold is installed with stripper; The bottom of cope match-plate pattern is installed with hollow backing plate, backing plate, punch fixing plate and die from top to bottom successively, punch fixing plate is installed with drift, hollow backing plate inherence is provided with buffer gear between its bottom surface and bottom surface of cope match-plate pattern, is fixedly connected with multiple contour post between hollow backing plate and die respectively.The utility model structure is simple, adopts the double protection structures of hollow backing plate and backing plate, and arrange buffer gear in hollow backing plate, serve good cushioning effect, protect mould, extend the mold use life-span; Adopt contour post to connect hollow backing plate and stripper simultaneously, improve the compatible degree that punch coordinates with die and stripper, thus improve the stability in blanking process.
Description
Technical field
The utility model relates to auto parts and components production and processing mould applications, specifically a kind of blanking die.
Background technology
In auto parts and components production and processing field, the general parts adopting mould to carry out processing metal product.Some are had to the parts of polymorphic structure, blanking die is the punch die of punch part or blank on sheet material, but the structure of existing blanking die is mostly complicated, poor stability in blanking process; In addition, except the die, punch, concave-convex mold etc. of structure uniqueness will be designed to meet except actual production processing needs, also need drift to have enough impulse forces, just can complete the processing of key position, this exerts a certain influence to undoubtedly the service life of mould itself.
Utility model content
The purpose of this utility model be in order to overcome prior art exist defect and deficiency, a kind of blanking die is provided.
The technical solution of the utility model is as follows:
A kind of blanking die, include upper and lower template, guide pin bushing, guide pillar and die shank, it is characterized in that: described lower bolster is installed with concave-convex mold fixed head, described concave-convex mold fixed head is installed with concave-convex mold, and the top of described concave-convex mold is installed with stripper; The die that the bottom of described cope match-plate pattern is installed with hollow backing plate, backing plate, punch fixing plate from top to bottom successively and matches with described concave-convex mold, described punch fixing plate is installed with the drift matched with described concave-convex mold, be provided with buffer gear between described hollow backing plate its bottom surface inherent and the bottom surface of described cope match-plate pattern, between hollow backing plate and described die, be fixedly connected with multiple contour post respectively.
Described blanking die, is characterized in that: described buffer gear is buffer spring.
The beneficial effects of the utility model:
The utility model structure is simple, adopts the double protection structures of hollow backing plate and backing plate, and arrange buffer gear in hollow backing plate, ensureing under the prerequisite that drift normally works, serve good cushioning effect, protect mould, extend the mold use life-span; Adopt contour post to connect hollow backing plate and stripper simultaneously, improve the compatible degree that punch coordinates with die and stripper, thus improve the stability in blanking process.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1, a kind of blanking die, include upper and lower template 9,1, guide pin bushing, guide pillar 10 and die shank 13, lower bolster 1 is installed with concave-convex mold fixed head 2, concave-convex mold fixed head 2 is installed with concave-convex mold 3, the top of concave-convex mold 3 is installed with stripper 4; The die 5 that the bottom of cope match-plate pattern 9 is installed with hollow backing plate 8, backing plate 7, punch fixing plate 6 from top to bottom successively and matches with concave-convex mold 3, punch fixing plate 6 is installed with the drift 11 matched with concave-convex mold 3, be provided with buffer spring 12 between hollow backing plate 8 its bottom surface inherent and the bottom surface of cope match-plate pattern 9, between hollow backing plate 8 and die 5, be fixedly connected with multiple contour post 14 respectively.
