Description

The contour structure of multistation progressive die

Technical field

the utility model relates to Stamping Die Technology field, exactly relates to a kind of contour structure of multistation progressive die.

Background technology

development along with industrial technology level, stamping parts structure becomes increasingly complex, to the required precision of stamping parts also more and more, therefore, multistation progressive die is applied more and more extensive in punching production, along with the extensive use of multistation progressive die in punching production, some structural deficiencies manifest gradually.In multistation progressive die, binder, stripper need to keep horizontal movement when work, and the horizontal movement of binder, stripper is generally guaranteed by contour unloading bolt (or device).Referring to Fig. 1 and Fig. 2, be the contour structure of existing a kind of multistation progressive die, this contour structure comprises packing ring 12, spring 16, is contour sleeve 15 cylindraceous and unloading bolt 14, and this unloading bolt 14 is soket head cap screw, upper bolster 11 has the through hole 11-1 of up/down perforation, on punch retainer 13 lower surfaces, has counterbore 13-2, has the guide through hole 13-1 of and up/down perforation corresponding with through hole 11-1 on the bottom surface of this counterbore 13-2, the upper end of contour sleeve 15 is sleeved in guide through hole 13-1 after being upward through counterbore 13-2, the inwall of this guide through hole 13-1 and the respective external wall of contour sleeve 15 are slidably matched, the inwall of this counterbore 13-2 and the respective external wall of contour sleeve 15 form the spatial accommodation of ring-type, spring 16 is arranged in spatial accommodation and is sleeved in the respective external wall of contour sleeve 15, the upper end of this spring 16 be resisted against on the corresponding ground of counterbore 13-2 and its lower end abutment in the respective upper surfaces of stripper 17, unloading bolt 14 is downwards successively through packing ring 12, after the endoporus of contour sleeve 15, be spirally connected fastening with stripper 17, the external diameter of packing ring 12 is less than the internal diameter of counterbore 13-2 and is greater than the internal diameter of guide through hole 13-1, like this spring 12 is compressed between the bottom surface of counterbore 13-2 and the upper surface of stripper 17, also contour sleeve 15 is fixed on stripper 17 simultaneously.Although the contour structure of this multistation progressive die can guarantee in stripper 17 levels, the requirement of lower motion, but because the head of screw of unloading bolt 14 is imbedded in the through hole 11-1 of upper bolster 11 darker, unscrewing, while tightening unloading bolt 14, can only use in the inner hexagonal hole of long-armed insertion unloading bolt 14 heads of inner hexagon spanner and pull, can make like this to unscrew, while tightening unloading bolt 14, relatively require great effort, and execute man-hour requirement and can adjust binder by adjusting the degree of tightness of unloading bolt 14 by after being arranged on multistation progressive die on forcing press and disassembling, stripping force, so the contour structural adjustment of existing multistation progressive die is inconvenient and effort.

Summary of the invention

the technical problems to be solved in the utility model is: the contour structure that a kind of easy to adjust and labour-saving multistation progressive die is provided.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of contour structure of multistation progressive die, described multistation progressive die comprises cover plate, upper bolster, convex mould pad, the punch retainer of arranging successively and interfixing from top to bottom, is arranged in the discharging backing plate of described punch retainer below and is fixed on the stripper on described discharging backing plate lower surface; This contour structure comprises elastomeric element, contour sleeve and unloading bolt; On described upper bolster, convex mould pad, there is respectively the through hole of up/down perforation, these two through holes are mutually corresponding, between described cover plate and this two through holes, form and have the blind hole shape spatial accommodation under shed, described punch retainer has the guide through hole of the corresponding and up/down perforation of opening with described spatial accommodation; On the upper end outer wall of described contour sleeve, there is the radially outward ring-type limiting section of projection, the external diameter of this limiting section is less than the internal diameter of described spatial accommodation and is greater than the internal diameter of described guide through hole, the lower end of this contour sleeve is passed down through and stretches out described guide through hole, the lower surface of this contour sleeve is resisted against on the upper surface of described discharging backing plate, and the inwall of this guide through hole and the respective external wall of this contour sleeve are slidably matched; Described elastomeric element is arranged in this spatial accommodation, and its one end is resisted against on cover plate, and its other end is resisted against on the upper surface of contour sleeve; On the upper surface of described discharging backing plate, there is endoporus with this contour sleeve corresponding and to downward-extension, connect the fixed via of described stripper; The endoporus that described unloading bolt is upward through described fixed via and described contour sleeve lower end is spirally connected fastening; Described contour sleeve has stop surface on the outer wall between described punch retainer and described discharging backing plate.

Described elastomeric element is spring.

Described fixed via is the catotropic countersunk head through hole of counterbore.

Described stop surface is two sides, is located at respectively on the outer wall that described contour sleeve is relative.

Described unloading bolt is soket head cap screw.

Useful technique effect of the present utility model is:

The utility model adopts unloading bolt to be upward through fixed via on punch retainer and the endoporus of contour sleeve lower end is spirally connected fastening and on the outer wall between punch retainer and discharging backing plate, stop surface is set at contour sleeve, during construction, first with spanner, be stuck in the spiral shell head of unloading bolt, with monkey wrench, be stuck on the stop surface on contour sleeve and can realize tightening or unscrewing of unloading bolt again, therefore, due to the spiral shell of unloading bolt of the present utility model upside down, during adjustment without pulling down multistation progressive die from forcing press, very convenient, the spiral shell head that spanner is stuck in unloading bolt is stuck on stop surface and can adjusts with monkey wrench again, very laborsaving.
