Description
Technical field
Diel field is the utility model is related to, specifically, the utility model is related to a kind of mould for preventing scraps-bounce
Tool.
Background technology
Punching press, be at room temperature, using the mould on forcing press to material apply pressure, make its produce separation or
It is plastically deformed so as to obtain a kind of pressure processing method of required part.During punching press, waste material should be clamped in the die cavity of cavity plate,
Under the promotion of follow-up waste material, fallen from the material-dropping hole of mould, but when drift is more than concave die cavity to waste material to the absorption affinity of waste material
Clamping force when, waste material will be with the surface that is up and jumping to female die of die of drift, the problem of generating scraps-bounce, main
It is that lubricating oil can be used in punching course to want reason, and waste material is produced vacuum suction by oil film adhesion or punch-pin end face.Waste material
The upper jump laminate surface that can liquidate produces bad impression, has a strong impact on the exterior quality of stamping products, even influences mould work sometimes
Make the life-span of part, so as to influence the precision of mould, be largely affected by stamping production efficiency.
Utility model content
A purpose of the present utility model is that solve at least the above, and provides the advantages of at least will be described later.
The utility model also has a purpose to be to provide a kind of mould for preventing scraps-bounce, by the inwall of cavity plate
Some grooves are opened up, punch is provided with projection, when waste material is entered in cavity plate, is rubbed caused by between waste material side wall and groove
The absorption affinity that power is more than oil film is wiped, so as to which waste material will not be up with the rollback of drift, the technology for solving scraps-bounce is asked
Topic.
In order to realize according to these purposes of the present utility model and further advantage, there is provided a kind of mould for preventing scraps-bounce
Tool, including:
Upper module, it includes upper bolster, upper padding plate, fixed plate and stripper successively from top to bottom；
Punch, it is arranged on the upper module, and uniform intervals are provided with some projections on the punch；
Lower module, it includes lower template, lower bolster and die shoe successively from top to bottom；
Cavity plate, it is arranged in the lower template, and some grooves are offered on the inwall of the cavity plate.
Preferably, it is characterised in that there is blade clearance between the punch and the cavity plate.
Preferably, the thickness of the projection is more than the blade clearance.
Preferably, the quantity of the projection is 3~6.
Preferably, the position of the groove and the position of the projection correspond, the concave shape of the groove and institute
The convex shape for stating projection matches.
Preferably, the internal diameter of the cavity plate is gradually reduced along the motion path of waste material, to form chucking power to waste material.
Preferably, the lower bolster on the die shoe with offering relief hole.
The beneficial effects of the utility model are：This case on the inwall of cavity plate by opening up groove, while in punch
On add projection so that produce a frictional force between the waste material side wall and groove gone out, while the internal diameter of cavity plate is along waste material
Motion path and be gradually reduced, cavity plate inwall can to waste material produce chucking power so that drift retract when waste material will not be up time
Skip to molding surface.
Brief description of the drawings
Fig. 1 is the structural representation of diel of the present utility model；
Fig. 2 is the top view of cavity plate；
Fig. 3 is the structural representation of punch and the enlarged drawing of projection；
Fig. 4 is the cooperation schematic diagram of punch process convex mould drift and cavity plate.
Embodiment
The utility model is described in further detail in conjunction with the embodiments referring to picture, to make people in the art
Member can implement according to this with reference to specification word.
As shown in figure 1, a kind of mould for preventing scraps-bounce is listed in this case, its entirety includes：Can upper and lower vertical separation
Upper module and lower module.
Upper module, it is connected with upper bolster 1, upper padding plate 2, fixed plate 3 and stripper 4 in turn from top to bottom.Punch-pin rushes
First 10 are arranged on module, as shown in figure 3, some projections 101 are evenly arranged with the side wall of punch 10 at certain intervals,
The number of projection 101 is 3~6, and 4 projections 101 are employed in the present embodiment, can be selected according to actual conditions suitable convex
The number of block 101.
Lower module, it includes lower template 6, lower bolster 7 and die shoe 8 successively from top to bottom.One is provided with lower template 6
Cavity plate 9, as shown in Fig. 2 uniform intervals offer some grooves 11, the concave shape and projection of groove 11 on the inwall of cavity plate 9
101 convex shape matches, the size for being dimensioned slightly smaller than projection of groove 11 so that groove 11 produces to the side wall of waste material 5
One clamping force, the position of groove 11 correspond with the position of the projection 101 on punch 10.As shown in figure 4, punch
There is a blade clearance a, the thickness of projection 101 is more than blade clearance a, and such waste material is entering to cavity plate 9 between 10 and cavity plate 9
When interior, the side wall of waste material 5 can be in contact with the cell wall of groove 11, and frictional force, cavity plate 9 are produced between waste material 5 and groove 11
Motion path of the internal diameter along waste material 5 and be gradually reduced, so as to which the inwall of cavity plate 9 produces a chucking power to the lower end of waste material 5,
The double action of frictional force and chucking power causes the waste material 5 in back off procedure of punch 10 up therewith will not knock-on to cavity plate
9 surfaces, waste material 5 are stayed in cavity plate 9, promote previous waste material descending when next waste material is entered in cavity plate 9, lower bolster 7
And relief hole is offered on die shoe 8, final waste material 5 is fallen along lower bolster 7 and the relief hole on die shoe 8.
In above-mentioned technical proposal, when upper module is descending, driving punch 10 is punched, and waste material is dropped down onto in cavity plate 9, on
The up driving punch 10 of module retracts.Because the side of punch 10 is provided with projection 101, set on the inwall of cavity plate 9
Fluted 11, friction is produced between the side wall and groove 11 of waste material 5, while the inwall of cavity plate 9 can also produce a clamping to waste material
Power so that waste material will not be up with the rollback of punch 10.The next part of punching press, waste material are entered in cavity plate 9 and pushed away
Move previous waste material to move down, final waste material is pushed in the relief hole on lower bolster 7 and die shoe 8, is given up along relief hole
Material falls into particular space.
From the above mentioned, the punch die of the present utility model for preventing scraps-bounce, by adding projection on punch 10,
Groove 11 is opened up on cavity plate 9 so that a friction is produced between waste material and groove 11, while the die cavity 12 of cavity plate 9 also can be to waste material
Produce a chucking power so that the waste material in back off procedure of punch 10 up will not knock-on to the surface of cavity plate 9, simple in construction
And effect is good.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new.
