Abstract

The utility model discloses an upper rolling die cutter which comprises a die cutter body, wherein the die cutter body is provided with a plurality of cutting blades and is of a flat plate shape; and the rolling die cutter further comprises a rolling canister. Since the rolling-type die cutter is adopted, when a complicated upper with various patterns is cut, only the part, which is tangential to the upper of shoe, of the rolling canister or the cylindrical die cutter body is a stressed area, so that the stressed area is reduced and the resistance is reduced; and under the condition of unvaried blanking force, the pressure is greater, blanking can be carried out more easily, and the working efficiency and the product percent of pass can be greatly improved.

Description

Group's face roll extrusion cutting die

Technical field

The utility model belongs to the technology of die manufacturing field, is specifically related to a kind of group face roll extrusion cutting die.

Background technology

The shoes group face blanking knife model that generally uses at present generally comprises the cutting die body of group's face shape, and the cutting die body is provided with the stamping-out cutter, and the cutting die body is processed by the sheet metal of broad, through blanking pressure group's face is cut moulding.Existing group face stamping-out generally all is that blanking knife model is fixed, and clicker press machine is pressed down fast, help then face the blanking pressure effect under promptly quilt cut into blanking knife model on identical hollow out or the pattern of shape.If but group's face area is bigger, styles such as hollow out or pattern are more on group's face, and group's face pattern is very complicated; The position of its required stamping-out is a lot, just causes the resistance of stamping-out to increase, and makes cut-off knife be difficult for sweeping away; Some pattern just stamping-out is not thorough, and qualification rate is not high, influences group's face whole structure.

Summary of the invention

The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and a kind of group face roll extrusion cutting die is provided, and it can adapt to the stamping-out of a lot of complicacy group face of style, increases work efficiency greatly and product percent of pass.

The technical scheme that the utility model adopted is: a kind of group face roll extrusion cutting die, comprise the cutting die body, and said cutting die body is provided with some blades that cut, and said cutting die body is a tabular, and said roll extrusion cutting die also comprises drum roll.

As preferably, the two ends of said drum roll are pivot end.

As preferably, form the cavity of hollow in the said drum roll.

As preferably, the width of said drum roll is greater than the Breadth Maximum of said cutting die body.

A kind of group face roll extrusion cutting die comprises the cutting die body, and said cutting die body is provided with some blades that cut, and said cutting die body is cylindric, and the said blade that cuts is positioned at said cutting die body outer wall.

As preferably, said cutting die body two ends are pivot end.

The beneficial effect of the utility model is: because the utility model adopts the cutting die of rolling-type, when the complicacy group face with more style was cut, its lifting surface area only had drum roll and the tangent position of shoes group face (or cylindric cutting die body and shoes group face); Its lifting surface area reduces; Resistance reduces, and under the constant situation of blanking pressure, it is bigger that pressure becomes; Be easier to stamping-out, increase work efficiency greatly and product percent of pass.

Description of drawings

Fig. 1 is the utility model embodiment one structural representation;

Fig. 2 is the utility model embodiment two structural representations.

Among the figure: 1, cutting die body; 2, cut blade; 3, drum roll; 4, pivot end.

The specific embodiment

To combine accompanying drawing and specific embodiment that the utility model is done further explain below.

Embodiment one: as shown in Figure 1, a kind of group face roll extrusion cutting die comprises cutting die body 1; Said cutting die body 1 is provided with some blades 2 that cut; Said cutting die body 1 is a tabular, and said roll extrusion cutting die also comprises drum roll 3, and the two ends of said drum roll 3 are pivot end 4; Form the cavity of hollow in the said drum roll 3, the width of said drum roll 3 is greater than the Breadth Maximum of said cutting die body 1.

Because the utility model adopts the cutting die of rolling-type, when the complicacy group face with more style was cut, its lifting surface area only had drum roll 3 and the shoes group tangent position of face; Its lifting surface area reduces; Resistance reduces, and under the constant situation of blanking pressure, it is bigger that pressure becomes; Be easier to stamping-out, increase work efficiency greatly and product percent of pass.

Embodiment two: a kind of group face roll extrusion cutting die, comprise cutting die body 1, and said cutting die body 1 is provided with some blades 2 that cut, and said cutting die body 1 is cylindric, and the said blade 2 that cuts is positioned at said cutting die body 1 outer wall, and said cutting die body 1 two ends are pivot end 3.

When the complicacy group face with more style is cut; Its lifting surface area only has cylindric cutting die body 1 and the shoes group tangent position of face, and its lifting surface area reduces, and resistance reduces; Under the constant situation of blanking pressure; It is bigger that pressure becomes, and is easier to stamping-out, increases work efficiency greatly and product percent of pass.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
