Description
Technical field
It the utility model is related to handware stamping area, and in particular to a kind of high applicability acute angle stamping die.
Background technology
Stamping die, is in Cold Press Working, by material（Metal is nonmetallic）It is processed into part（Or semi-finished product）'s
A kind of special process equipment, is known as cold punching die（It is commonly called as cold-punching mould）.Punching press, is at room temperature, using installed in forcing press
On mould pressure is applied to material, it is produced separation or plastic deformation, so that a kind of pressure processing of part needed for obtaining
Method.
It is in the majority with handware stamping die in stamping die, can by punching press since metal has good ductility
It is produced plastic deformation, also because metal has ductility, when punching press separates, the metal of incision can not be avoided to produce modeling
Property deformation, so as to form incomplete notch.Hardware plate punching more especially with acute angle is increasingly difficult, using common
Bottom is difficult to ensure that the planarization of notch for the punch of plane, yielding；If punch notch correspondence position set blade into
Row punching press, since acuter angles are more fragile, punching press repeatedly easily causes blade passivation or even crumbles, and punching can only be replaced after damage
Head, it is of high cost.
Utility model content
The utility model aim is to provide a kind of high applicability acute angle stamping die, it can be efficiently solved in background technology
The problems of.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of high applicability acute angle stamping die, including rack, the upper rack be provided with punch and driving punch into
The driving cylinder of row punching press, the frame lower are provided with putting groove, and punching press corresponding with punch is provided with the putting groove
Groove, the punch at least one end are acute angle, and the punch includes matrix and the detachable pressing block being arranged on the outside of matrix, described
The end of pressing block is the acute angle end of punch, and the pressing block bottom is provided with the cutting edge extended from inside to outside.
It is punched out during use by driving cylinder to drive punch to push, it is contemplated that the acute angle end of punch is tied to be fragile
Structure, punching is easily impaired repeatedly, causes punch to be scrapped after impaired, therefore acute angle end is arranged on pressing block, and pressing block can
Remove and install on the outside of matrix, punching press only needs to change pressing block after being damaged, easy to use, saves cost, improves resource profit
With rate, and the setting of cutting edge ensures that pressing block can ensure the planarization of notch when being punched out.
Further, described matrix bottom is provided with the knife of supercharging protrusion, the raised end face of the supercharging and cutting edge
Cutting edge of a knife or a sword is in same level.
Punch is punched out the planarization that can ensure notch using cutting edge, and opposite cutting edge is easily damaged；
Punch is punched according to plane, and durability is good, and notch, which lacks, is difficult to ensure that planarization；The utility model is provided with supercharging protrusion, makes
The knife edge of its end face and cutting edge is in same level, relative to pressure of the plane punching with bigger, and relative to list
Pure cutting edge punching can be good at alleviating the pressure of cutting edge, protect cutting edge.
Further, described matrix at least one end is arranged to acute angle, and the pressing block is sharp for parcel matrix acute angle end
Angle inclusion enclave.
Limit matrix and be provided with acute angle, pressing block is acute angle inclusion enclave, can make pressing block with having higher between matrix
Binding face, bonding strength is good.
Further, the supercharging protrusion is acute angle-shaped protrusion, the angle pair of the raised angle of the supercharging and pressing block
Should.
It is more uniform to the hardware plate stress that should be able to make area to be punched to be pressurized the angle of raised angle and pressing block, into
One step alleviates the stress of cutting edge.
Further, the pressing block is removably mounted on the outside of matrix by lock screw.
The beneficial effects of the utility model are：
The utility model sets dismountable pressing block to be installed on matrix and forms punch, and cutter are set in pressing block
Sword, after punching press is repeated, the pressing block being damaged to acute angle end can replace processing, save production cost, save
Resource.

Fig. 2 is the partial structural diagram of the utility model.
Embodiment
In order to make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As Figure 1-Figure 2, a kind of high applicability acute angle stamping die, including rack 1,1 top of rack are provided with
Punch 2 and driving punch 2 carry out the driving cylinder 3 of punching press, and 1 lower part of rack is provided with putting groove 4, in the putting groove 4
Stamped groove 5 corresponding with punch 2 is provided with, the punch 2 at least one end is acute angle, and the punch 2 is including matrix 6 and detachably
The pressing block 7 in the outside of matrix 6 is arranged at, the end of the pressing block 7 is the acute angle end of punch, 7 bottom of pressing block
It is provided with the cutting edge 8 extended from inside to outside.
6 bottom of described matrix is provided with supercharging protrusion 9, and the end face of the supercharging protrusion 9 and the knife edge of cutting edge 8 are in
Same level.
At least one end of described matrix 6 is arranged to acute angle, and the pressing block 7 wraps up for the acute angle of parcel 6 acute angle end of matrix
Body.
The supercharging protrusion 9 is acute angle-shaped protrusion, and the angle of the supercharging protrusion 9 is corresponding with the angle of pressing block 7.
The pressing block 7 is removably mounted to the outside of matrix 6 by lock screw 10.
It is the wherein specific implementation of the utility model above, therefore its description is more specific and detailed, but can not be
And it is interpreted as the limitation to the utility model patent scope.It should be pointed out that for those of ordinary skill in the art,
Without departing from the concept of the premise utility, various modifications and improvements can be made, these obviously replace shape
Formula belongs to the scope of protection of the utility model.
