Description
Technical field
The utility model relates to a kind of sheet-metal press working mould, especially a kind of diel that is used for ultrashort thick material towards aperture.
Background technology
The aperture that runs into institute's punching in the sheet-metal press working process through regular meeting is less than the thick situation of material, and this belongs to thick material towards aperture.Its punching has not been a simple shear history, but by punch material is expressed to die periphery plasticity separating process again.When extruding, punching part material is pressed against the periphery in hole, and after the die sinking, punch is killed in the material resilience that is pressed against periphery; In addition, because after the influence of shape, size and the periphery hole in hole made that part material deformation inconsistent or Kong Chong in edge, hole wears, the cross force that the press frame resilience produces forced the upper and lower mould changing of the relative positions and causes punch to fracture.Therefore, guarantee thick material, intensity and rigidity in the time of just must improving punch work, and the rigidity of entire die and stability towards the carrying out continuously of aperture process.For this reason, the following method of general normal employing solves: the one, and adopt the structure of punch total length or local guiding to prevent that punch from fractureing; The 2nd, adopt the structure of ultrashort punch to prevent that punch from fractureing.Method one requires guide pad or guide plate to make the assembly precision height, and will adopt float die shank and ball guide pillar guide pin bushing mould bases, totle drilling cost height; Method two clashes into ultrashort punch by impact block finishes punching, and its deficiency is also to adopt float die shank and ball guide pillar guide pin bushing mould bases, and punch is in quick condition, and length reaches 20～30mm, and rigidity is still relatively poor, and die assembly is originally equally also high.Therefore, how reliable, high-quality, guarantee that the stable of thick material stamping-out process carries out, and just become a research emphasis at low cost.
Summary of the invention
The present invention will provide a kind of floating type ultrashort thick material aperture punch die, is used to solve the poor rigidity of existing mold, this high technical problem of die assembly.
Floating type ultrashort thick material towards little casement for reliable, high-quality, realize that thick material stamping-out process provides a kind of resulting structure at low cost.
For achieving the above object, the technical solution of the utility model is: a kind of floating type ultrashort thick material aperture punch die, comprise the part of the upper die, and the part of the lower die is characterized in:
Part of the upper die: comprise mould bases, the die shank that floats, floating punch; Mould bases is made of auxiliary guide pillar, straight pin, upper bolster, hollow backing plate, holding pad, punch fairlead; The die shank that floats is made of ball seat, the die shank that floats, fixed mount, fixed mount backing plate, flexible member; Floating punch is made of auxiliary guide pin bushing, floating saddle, punch retainer, aperture punch; Wherein, positioning and fixing connects hollow backing plate and holding pad below the upper bolster, be placed with punch retainer between upper bolster and the holding pad, and be equipped with the aperture punch above the punch retainer, be provided with the punch fairlead of respective apertures punch above the holding pad, punch retainer is connected with the floating saddle positioning and fixing, is slidingly connected by auxiliary guide pillar and auxiliary guide pin bushing between punch retainer and the holding pad; Floating saddle is by steel bushing and upper bolster sliding connection; Connection Bracket backing plate, fixed mount and unsteady die shank successively on the floating saddle upper surface are placed flexible member between fixed mount backing plate and the upper bolster, the ball seat that is fixed on the floating saddle is housed in the fixed mount, and ball seat are connected with unsteady die shank hinge.
The part of the lower die: comprise framed, roller guide pillar guide pin bushing, die shoe, spring, backing plate, insert die and die frame, wherein, inserting between die and the die frame is that interference fit connects, die frame, backing plate and framed between connect by screw, solid pin is located; Framedly be connected by soket head cap screw, Gu pin is fixed with die shoe; Upper and lower mould part is slidingly connected by roller guide pillar guide pin bushing guiding, and guide pillar is provided with spring outward.
Between aperture punch and the punch retainer, between auxiliary guide pin bushing and the punch retainer, between auxiliary guide pillar and the holding pad, between punch fairlead and the holding pad, be interference fit between steel bushing and the upper bolster.
Floating saddle is connected by soket head cap screw with punch retainer, the straight pin location.Holding pad, hollow backing plate are connected by soket head cap screw with upper bolster, the straight pin location.
The beneficial effects of the utility model are:
(1) adopting punch retainer is floating structure, and auxiliary little guide pillar leads to punch retainer.Holding pad is a fixed structure simultaneously, and only 5mm is thick, and small punch leads by the little guide pin bushing that is fixed on the holding pad, and it is relatively poor that these structures have solved the punch strength that adopts common punch die to bring, and is easy to the problem that causes that punch fractures.Die clearance uniformity when having guaranteed punching press has improved the stability of punching press.
(2) whole mould bases adopts triple guiding: the guiding of holding pad adopts built-in little guide pillar, guide pin bushing guiding; The guiding of upper and lower mould adopts ball guide pillar, guide pin bushing structure; Moving up and down of floating punch relies on the steel bushing guiding that is fixed on upper bolster.The precision that all these have improved the punch motion has prevented the gap fluctuation in the stamping-out process, simultaneously the thickness of holding pad, punch retainer is reduced greatly, makes aperture punch length be reduced to 12～15mm, greatly improves punch rigidity and life-span.
The utility model provides a kind of stable, reliable method for being engaged in sheet-metal press working aperture manufacturing enterprise, has improved production efficiency and the product quality of thick material towards aperture, has reduced cost.Adopt this structure, first entire die has triple guiding, and adopts the rolling element guiding, improves greatly die life, punching course is more stable, and percent defective is lower; It two is to adopt holding pad to fix and structure that punch floats, and punching stroke is little, and punch length is shorter, and 12～15mm has only greatly improved the rigidity and the intensity of aperture punch; Its three mould adopts the piece form, and maintenance, processing, heat treatment are conveniently.In a word, this invention provides a kind of new structure of high-quality, High-efficient Production towards the aperture field for thick material.
