Abstract
The invention discloses a multi-process composite die for drawing forming, comprising an upper die base, an upper die plate, a lower stripper plate, a lower die plate, a lower fixing plate, a lower die base and die pads, wherein the upper die plate is arranged at the lower surface of the upper die base; the lower fixing plate and the die pads are respectively arranged at the upper and lower surfaces of the lower die base; the lower stripper plate and the lower die plate are arranged on the lower fixing plate; and a puncture punch is arranged at a position on the upper die plate, which corresponds to the lower die plate. The multi-process composite die disclosed by the invention hast the advantages that in the drawing forming process of a product, materials flow from the interior region to the outside in the forming process to ensure that the product does not crack.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of drawing and forming multiple operation composite die.
Background technology
In the production process of part, often use drawing and forming multiple operation composite die, product is carried out drawing and forming, in the process of drawing and forming, the material of product to flows outside, causes the generation of cracking phenomena by interior zone.
Summary of the invention
Goal of the invention: the objective of the invention is to deficiency, a kind of drawing and forming multiple operation composite die of avoiding the product cracking is provided to prior art.
Technical scheme: a kind of drawing and forming multiple operation composite die of the present invention; Comprise upper bolster, cope match-plate pattern, lower stripper, lower bolster, bottom plate, die shoe and bottom seat pad; The lower surface of said upper bolster is provided with cope match-plate pattern; The upper and lower surfaces of said die shoe is respectively arranged with said bottom plate and bottom seat pad, and said bottom plate is provided with said lower stripper and lower bolster, is provided with the corresponding position of said lower bolster on the said cope match-plate pattern and punctures drift.
Further, saidly puncture the central authorities that drift is positioned at said cope match-plate pattern.
The present invention compared with prior art, its beneficial effect is: the present invention makes product in the process of drawing and forming, its material is outwards flowed by interior zone in forming process, thereby product is not ftractureed.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Be elaborated in the face of technical scheme of the present invention down, but protection scope of the present invention is not limited to said embodiment.
