State the step waste knife that lower die trimming insert matches, the step waste knife be equipped with for the lower trimming cutting edge
Coordinate to be punched out the upper trimming cutting edge of stampings；It is additionally provided on the lower die holder for coordinating with the step waste knife
Cut off the embedded waste knife of stampings, the embedded waste knife is located at the lower section of the step waste knife, described
The interior upper angle of embedded waste knife is lowered cutting edge mouth, and the lower surface of the step waste knife is high outside and low outside second order step
The corner in face, the lower surface of the step waste knife is upper cutting edge port corresponding with the lowered cutting edge mouth, institute
It states the position of the top of embedded waste knife in the up-down direction and is less than the position of the lower trimming cutting edge in the up-down direction.
Further, the lower die trimming insert is equipped with charging conduit corresponding with the step waste knife, described embedding
Enter formula waste knife in the charging conduit, the charging conduit is separated into interior charging conduit and is fallen outside by the embedded waste knife
Hopper, lower die holder are equipped with the first scrap chute for be connected to the lower end of outer charging conduit, the lower die holder equipped with it is described interior
Second scrap chute of the lower end connection of charging conduit.
The utility model is by being arranged step waste knife and embedded waste knife, in the mistake that stampings is punched out
Stampings is cut off in journey so that stampings is divided into two, and while ensureing production efficiency, it is useless can to reduce punching press
Material is stuck in the possibility in diel.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is a kind of structural schematic diagram of stampings.
In figure：1-lower die holder；2-upper die holders；3-lower die trimming inserts；4-step waste knifes；5-is embedded useless
Expect knife；6-lower trimming cutting edges；7-upper cutting edge ports；8-lowered cutting edge mouths；9-bolts；10-positioning pins；11-the first is useless
Expect sliding slot；12-the second scrap chute；13-waste material main bodys；14-bar shaped waste materials；15-cutting lines.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of stampings trimming structure as shown in Figure 1, including upper die holder 2 and lower die holder 1, fixed peace on lower die holder 1
Equipped with lower die trimming insert 3, lower die trimming insert 3 is equipped with lower trimming cutting edge 6, and upper die holder 2 is equipped with and lower die trimming insert 3
The step waste knife 4 to match, step waste knife 4, which is equipped with, to give up for coordinating with lower trimming cutting edge 6 to be punched out punching press
The upper trimming cutting edge of material；It is additionally provided on lower die holder 1 and cuts off the embedded useless of stampings for coordinating with step waste knife 4
Expect that knife 5, embedded waste knife 5 are located at the lower section of step waste knife 4, the interior upper angle of embedded waste knife 5 is lowered cutting edge mouth
8, the lower surface of step waste knife 4 is high outside and low outside second order step surface, and high outside and low outside refers to the following table of step waste knife 4
The distance of the side of upper mold of the face on upper die holder 2 from the ground is more than side far from the upper mold on upper die holder 2 from the ground
The corner of distance, the lower surface of step waste knife 4 is upper cutting edge port 7 corresponding with lowered cutting edge mouth 8, embedded
The position of the top of waste knife 5 in the up-down direction is less than the position of lower trimming cutting edge 6 in the up-down direction.Step waste knife
4 are fixedly mounted on by bolt 9 and positioning pin 10 on upper die holder 2, and embedded waste knife 5 is equally by bolt 9 and positioning pin 10
It is fixedly mounted on lower die holder 1.Obviously in order to ensure that upper trimming cutting edge can be fully mated with lower trimming cutting edge 6 and be punched out
Waste material is pressed, the top of embedded waste knife 5 has to thicker than stampings with the spacing of lower trimming cutting edge 6 in the up-down direction
Degree is big, 2 times of the top of embedded waste knife 5 and the thickness that the spacing of lower trimming cutting edge 6 in the up-down direction is stampings
It is optimal selection to 3 times.
As a preferred embodiment, 5 outside upper angle of embedded waste knife is chamfering, to facilitate stampings from embedded waste knife 5
Upper landing.
