As a preferred version of the present invention, described liftout assembly comprises spring and ejection block.
As a preferred version of the present invention, described upper bolster is provided with die shank.
As a preferred version of the present invention, described push-rod assembly comprises symmetrically arranged two groups of pusher structures, described pusher structure comprises upper push-rod, intermediate push rod and lower push-rod, wherein one end of described upper push-rod, described intermediate push rod, described lower push-rod is hinged, and the other end is hinged with described die shoe, described moulding box and described slide respectively.
As a preferred version of the present invention, described upper bolster lower surface is provided with multiple guide pin bushing, and described die shoe is provided with multiple guide pillar, described guide pin bushing and described guide pillar adaptation.
As a preferred version of the present invention, described guide pin bushing and described guide pillar are 8.
As a preferred version of the present invention, described matrix cavity sidewall is fixed with stretching die protection block, and described stretching die protection block lower surface and described ejection block are fitted.
As a preferred version of the present invention, in matrix cavity, be provided with the blank holder for eliminating material stress of annular.
Drawing die provided by the invention connects moulding box on die shoe, in moulding box, cam structure is set, promote slide by the rotation of cam to move up and down, moving up and down of slide can promote lower bolster by push-rod assembly and move up and down, thus realizing the folding of mould, this structure makes drawing die folding with convenience, folding speed quickly, effectively improves production efficiency and the quality of production; Drawing die is provided with liftout assembly bottom matrix cavity; stretching die protection block is fixed with at matrix cavity sidewall; die protection block can be stuck in bottom matrix cavity liftout assembly; this structure solves because of the larger problem of the impact of die inner wall abrasion on tensioning member quality well, and reasonable in design, convenient disassembly, manufacturing cost be lower, be suitable for promoting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the drawing die that the specific embodiment of the invention provides.
Be labeled as in figure:
1, upper bolster; 2, die shoe; 3, punch fixed block; 4, stretching convex die; 5, stretching die; 6, moulding box; 7, cam; 8, slide; 9, die shank.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the drawing die that the specific embodiment of the invention provides.This drawing die comprises upper bolster 1 and the die shoe 2 that arrange corresponding to upper bolster 1, and wherein, upper bolster 1 lower surface is provided with punch fixed block 3, and punch fixed block 3 lower surface is fixedly installed stretching convex die 4; Die shoe 2 upper surface is provided with the stretching die 5 corresponding with stretching convex die 4, forms matrix cavity, be provided with liftout assembly bottom matrix cavity in stretching die 5; Die shoe 2 connects moulding box 6, and be provided with roller and push-rod assembly that cam 7, the slide 8 be connected with cam 7, slide 8 are installed in moulding box 6, wherein, liftout assembly comprises spring and ejection block.
Concrete, upper bolster 1 is provided with die shank 9; Push-rod assembly comprises symmetrically arranged two groups of pusher structures, and pusher structure comprises upper push-rod, intermediate push rod and lower push-rod, and wherein one end of upper push-rod, intermediate push rod, lower push-rod is hinged, and the other end is hinged with die shoe 2, moulding box 6 and slide 8 respectively; Matrix cavity sidewall is fixed with stretching die protection block, and this stretching die protection block is preferably metal material and makes, thus improves its service life.Stretching die protection block lower surface and ejection block are fitted, die protection block can be stuck in bottom matrix cavity liftout assembly, this structure solves because of the die inner wall abrasion problem larger to tensioning member quality influence well, and reasonable in design, convenient disassembly, manufacturing cost be lower, be suitable for promoting; The blank holder for eliminating material stress of annular is provided with in matrix cavity.
