Description
Technical field
The invention belongs to stamping die technologies, and in particular to a kind of large-scale covering shaving die.
Background technique
Automobile die the degree of automation is higher and higher, and many automobile main frame maker use multi-station mold and automated production
Line is produced.It removes other than other reasons such as press, punching press stability, process arrangement, influences the main of stamping production efficiency
Factor removes product quality, just belongs to the problem of deburring waste material excludes.On the one hand the exclusion of deburring waste material requires Sheet Metal Forming Technology to arrange
Rationally, on the other hand to mould structure it is also proposed that very big requirement, so this is one big to the mould process designed capacity of main engine plants
Test.
For one Trimming Die of a mould, the waste material on part periphery is difficult to exclude.And limited by die space,
The downslide that often can all influence waste material, causes waste from stacking, leads to deburring efficiency and edge-neatening efffct indirectly.Waste from stacking when serious
It will cause the generation of burn failure and mold accident.There is also the lower defects of efficiency for trimming die in the prior art.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of large-scale covering shaving die is provided.
A kind of large-scale covering shaving die, comprising:
Inside is the punch-pin fixing seat of cavity；
It can be along the pressure plate that punch-pin fixing seat inner cavity slides up and down；
It is fixed on the trimming punch of punch-pin fixing seat lower end；
Cutter uniformly distributed, for cutting off waste material；
It is characterized by: the pressure plate is arranged in the inner cavity of punch-pin fixing seat, under the inside of the trimming punch, pressure plate
The outside at end, the outside of cavity plate upper end are located in same vertical plane, and the positive bottom of trimming punch is equipped with cutter, and pressure plate is by zero
Part is pressed abd fixed on pedestal, on cavity plate, pressure plate, pedestal side be equipped with the face matched with part, cavity plate is fixed on bottom
The outside in the outside on seat top, the pressure plate lower part is equipped with limited step, and the punch-pin fixing seat is fixed on the bottom of upper die holder
Portion.
Preferably, the pressure plate is connected with the lower end of guide rod, and the top of the guide rod passes through the slide opening on upper die holder,
The outside of the guide rod is equipped with spring, and the upper and lower side of the spring is connected with upper die holder, pressure plate respectively.
Preferably, inclined waste material chute is fixed on the outside of the pedestal top.
Preferably, the ejector beam that can be slided up and down is equipped in the pedestal, the upper end of the ejector beam is fixed with liftout
Block, the upper surface of the ejection block are aligned with the lower end surface of part.
Compared with prior art, beneficial effects of the present invention:
In the use of the present invention, part is placed on pedestal, the part for needing to carry out trimming deburring is stretched out from cavity plate top, pressure
Machine driving upper die holder move down, with feature contacts, part is compressed first for pressure plate, pressure plate stopping move down, punch-pin fixing seat after
Continuous to move down, part is needed the partial die cut of deburring to get off by trimming punch, is punched the waste material to get off and is continued to move down, waste material is in blank
It is cut into particle under the action of knife, and is discharged along waste material chute, after completing punching, upper die holder is moved up, and pressure plate remains pair
Part is compressed, until moving on to topmost in pressure plate, cylinder or Driven by Hydraulic Cylinder ejector beam are moved up at this time, completes discharging.
By the way that pressure plate is arranged, it is ensured that in punching, part is in the state being compacted, and ensure that the quality of part, protects
The efficiency of punching is demonstrate,proved；
Waste material is shredded by setting cutter, waste material is smoothly discharged, has the advantages that waste material is easy to be discharged.

Specific embodiment
Referring to Fig. 1, a kind of large-scale covering shaving die, comprising:
Inside is the punch-pin fixing seat 2 of cavity；
It can be along the pressure plate 5 that 2 inner cavity of punch-pin fixing seat slides up and down；
It is fixed on the trimming punch 8 of 2 lower end of punch-pin fixing seat；
Cutter 9 uniformly distributed, for cutting off waste material；
It is characterized by: the pressure plate 5 is arranged in the inner cavity of punch-pin fixing seat 2, the inside of the trimming punch 8, binder
The outside of 5 lower end of plate, the outside of 13 upper end of cavity plate are located in same vertical plane, and the positive bottom of trimming punch 8 is equipped with cutter 9,
Part 6 is pressed abd fixed on pedestal 11, on cavity plate 13 by pressure plate 5, pressure plate 5, pedestal 11 side be equipped with and part 6 matches
The face of conjunction, cavity plate 13 are fixed on the outside on 11 top of pedestal, and the outside of 5 lower part of pressure plate is equipped with limited step, described convex
