Description
Technical field
The utility model relates to a kind of diel of precision part.
Background technology
Existing punching die structure, because the fixing improper of meticulous punch causes punch to fracture and damage, upper and lower mould deviations is comparatively large, and clearance between punch and die precision is inadequate, and then affects die life, and there is the problems such as dismounting inconvenience.
Summary of the invention
Problem to be solved in the utility model is, because the fixing improper of meticulous punch causes punch to fracture and damage.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of diel of precision part, comprise upper bolster, die shoe, punch, upper mounted plate, bottom plate, elasticity stripper, die, backing plate and block rubber, described upper mounted plate is arranged on below upper bolster, be provided with backing plate between described upper mounted plate and upper bolster, described upper bolster, backing plate are fixedly connected with pin by soket head cap screw with upper mounted plate;
Described punch upper end is provided with cocked bead, described upper mounted plate center is also provided with the groove that same punch cocked bead matches, described punch runs through upper mounted plate, block rubber and elasticity stripper, described punch lower tail is 0.5 ~ 1cm to elasticity stripper lower surface distance, described block rubber is arranged on below upper mounted plate, the cylinder of through hole is provided with centered by described block rubber, described block rubber upper and lower surface is smooth flat, and described elasticity stripper is arranged on below block rubber;
Described die is arranged on below elasticity stripper, described die lower tail is provided with similar shape boss, described bottom plate center is provided with the through hole with die similar shape, described bottom plate lower tail is also provided with the inside groove matched with die lower projection, described bottom plate is enclosed within die outer rim and is surrounded, described die is fixed by bottom plate, and described bottom plate is fixedly connected with soket head cap screw by straight pin with die shoe.
Further, described elasticity stripper horizontal plane is rectangle, and described elasticity stripper thickness is 8 ~ 12cm.
Further, described upper mounted plate, block rubber and elasticity stripper socket cap unloading bolt are fixed on upper bolster.
Further, described die can be cube or cylinder.
Further, described block rubber can adopt polyurethane rubber block, nitrile rubber block, silicon rubber block or fluorubber block.
Further, described pin, straight pin and soket head cap screw are 4.
Operation principle: in blanking process, forcing press force forces upper bolster to drive upper mounted plate and punch to move down, until stripper engagement concavity mold pressing contracting block rubber, punch continues to complete blanking process downwards, the upper mounted plate arranged around whole blanking process convex mould and block rubber play the effect of guiding and protection punch, and suitable reduces the probability fractureed in punch blanking process; Boss under die around tail end is pushed down by the inside groove that bottom plate mates, and effectively secures die, improves the positioning accurate parasexuality of concave-convex mold, and then reduces gap deviation, improves the mold use life-span;
In discharge process, forcing press moves, while upper bolster drives and punch moves, block rubber loses the power from forcing press, and reverse resilience promotes elasticity stripper and completes discharge process.
The advantage that the utility model has and good effect are: this mould adopts fixed head and block rubber to surround the design of punch, reduce the fixing improper probability causing punch to fracture and damage because of thinner punch, block rubber and elasticity stripper serve the double action of discharging and binder simultaneously, die edge is fixing by bottom plate entirety, reduce upper and lower mould deviations, entirety adds the mold use life-span and operation for convenience detach.

Detailed description of the invention
A kind of diel of precision part, comprise upper bolster 4, die shoe 1, punch 9, upper mounted plate 11, bottom plate 2, elasticity stripper 10, die 7, backing plate 3 and block rubber 8, described upper mounted plate 11 is arranged on below upper bolster 4, be provided with backing plate 3 between described upper mounted plate 11 and upper bolster 4, described upper bolster 4, backing plate 3 are fixedly connected with pin 13 by soket head cap screw 5 with upper mounted plate 11;
Described punch 9 upper end is provided with cocked bead, described upper mounted plate 11 center is also provided with the groove that same punch 9 cocked bead matches, described punch 9 runs through upper mounted plate 11, block rubber 8 and elasticity stripper 10, described punch 9 lower tail is 0.5 ~ 1cm to elasticity stripper 10 lower surface distance, described block rubber 8 is arranged on below upper mounted plate 11, the cylinder of through hole is provided with centered by described block rubber 8, described block rubber 8 upper and lower surface is smooth flat, and described elasticity stripper 10 is arranged on below block rubber 8;
Described die 7 is arranged on below elasticity stripper 10, described die 7 lower tail is provided with similar shape boss 12, described bottom plate 2 center is provided with the through hole with die 7 similar shape, described bottom plate 2 lower tail is also provided with the inside groove matched with die 7 lower projection 12, described bottom plate 2 is enclosed within die 7 outer rim and is surrounded, described die 7 is fixed by bottom plate 2, and described bottom plate 2 is fixedly connected with soket head cap screw 5 by straight pin 6 with die shoe 1.
Further, described elasticity stripper 10 horizontal plane is rectangle, and described elasticity stripper 10 thickness is 8 ~ 12cm.
