Description
Technical field
The present invention relates to a kind of auto parts cold stamping Trimming Die, belong to Stamping Die Technology field.
Background technology
Many stamping parts need to carry out trimming process step after molding procedure in auto parts production process, unnecessary to shear
Process residue.Carrying out the Trimming Die of trimming process step includes the upper mould of upper trimming edge and the lower mould with lower trimming edge, on
When mould and lower mould matched moulds, upper trimming edge and lower trimming edge cut off unnecessary process residue.
The content of the invention
It is an object of the present invention to provide a kind of auto parts cold stamping Trimming Die, auto parts cold stamping trimming die
Tool efficiently deburring operate, and upper molding compound core and support punch-pin between set it is some to elastomer and balance weight, Yi Jishang
Set between mould fission_typed punch and lower molding compound core it is some the precision of deburring is substantially increased to elastomer and balance weight,
Cut repair it is more laborsaving, more neat；Process is effectively reduced, cost is reduced.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of auto parts cold stamping Trimming Die, bag
Upper die and lower die are included, the upper mould further comprises upper bolster, upper molding compound core, 4 lifting portions and embedded upper molding compound in-core
Upper mould fission_typed punch, the upper bolster two ends are respectively arranged with left and right boss, and this upper bolster center has depressed area, institute
State molding compound core, upper mould fission_typed punch to be embedded in the first depressed area, the upper molding compound in-core side is split type with upper mould
Punch-pin lateral surface is slidably connected by some coincide to upper guide plate, between upper the molding compound core lateral surface and depressed area medial surface
It is slidably connected by some coincide to upper guide plate, the upper mould fission_typed punch fringe region is made up of several cutter blocks, described
Upper mould fission_typed punch center is provided with several elastomers on first；
The lower mould further comprises die shoe, support punch-pin and lower molding compound core, and the center of the support punch-pin has
Second depressed area, this second depressed area bottom is provided with several first time balance weight, guide pillar and springs, under the spring is located at
Below the stripper of molding compound core, the guide pillar runs through the T-shaped through hole of stripper, and the flange positioned at guide pillar one end is logical positioned at T-shaped
Hole top and the lower diameter for having a diameter larger than T-shaped through hole, first time balance weight are embedded in the through hole of stripper and exposed and move back
The surface of flitch, the stripper fringe region is intervally distributed with several blank holder inserts；
It is provided with the left and right outside the boss wall on the upper slide coordinated with lower skateboard, this upper slide with interval
Several through holes are provided with, this through hole is embedded with graphite column；The two ends of the die shoe have left and right gap slot respectively, this left side,
Lower skateboard is provided with the madial wall of right gap slot, is evenly spaced apart to be provided with several through holes on this lower skateboard, this through hole
It is embedded with graphite column；The square casing that 4 centers have hollow out through hole is installed on the die shoe close to four by articulate
Under individual corner, off working state, square casing is located under die shoe upper surface, working condition, and square casing is located at die shoe
Side surface.
Further improved technical scheme is as follows in above-mentioned technical proposal：
Preferably, the support punch-pin edge of the lower mould is evenly distributed with several second time balance weight, the upper mould
Upper molding compound core on be distributed elastomer on corresponding with second time balance weight second.
Because above-mentioned technical proposal is used, the present invention has following advantages and effect compared with prior art：
1st, auto parts of the present invention cold stamping Trimming Die, upper molding compound core and support punch-pin are first fixed when its punching press is descending
Position workpiece to be processed after, then by upper mould fission_typed punch by workpiece to be processed progress deburring operate, while upper mould fission_typed punch
Also lower molding compound core can be driven descending, after deburring is completed, upper mould fission_typed punch is up, now, and lower molding compound core is in its bullet
Stripper is up under the promotion of spring, completes the retainer operation of workpiece to be processed, realizes efficiently deburring operation, and upper molding compound
What is set between core and support punch-pin is some between elastomer and balance weight, and upper mould fission_typed punch and lower molding compound core
Set it is some the precision of deburring is substantially increased to elastomer and balance weight, cut and repair more laborsaving, more neat, improve
Diel overall balance and buffering, reduce the infringement that vibrations and strong impulsive force are caused to material, meanwhile, keep
Stress balance during contact, also reduces the rate of decay of mould, effectively reduces process, reduce cost.
2nd, it is provided with and matches somebody with somebody with lower skateboard on auto parts of the present invention cold stamping Trimming Die, its left and right outside the boss wall
Several through holes are provided with interval on the upper slide of conjunction, this upper slide, and this through hole is embedded with graphite column；The die shoe
Two ends there is left and right gap slot respectively, be provided with lower skateboard on the madial wall of this left and right gap slot, on this lower skateboard
Even to be positioned apart from several through holes, this through hole is embedded with graphite column, both improves intensity, in turn ensure that the precision of guiding,
Side force is counteracted, so as to ensure the precision of stamping products, reliability and stability；Secondly, the graphite column tool in slide plate
There is the function of absorbing lubricating oil, it is ensured that high-lubricity and stability are kept in the multiple Reusability of upper die and lower die, is improved
The quality of quality of materials.
3rd, auto parts of the present invention cold stamping Trimming Die, its square casing around hinge rotation rolls up die shoe, when going out
During existing improper phenomenon, when under upper punch, first press on square casing, because square casing center has hollow space, therefore side
The pressure from upper mould is offset in shape casing deformation, and the pressure square casing that it also avoid at 50 tons, which flies out, hurts operating personnel,
So as to protect product, lower mould and operating personnel, security is improved；Secondly, insert is installed in its work pieces process area, it is ensured that
Vulnerable areas is readily replaceable in lower die worker's part processing district, and part is only repaired during maintenance, cost and raising is greatly reduced
Convenience.
