Description

Mould with knife edge not prone to fracture

Technical Field

The utility model belongs to the mould field, concretely relates to difficult cracked mould of edge of a knife.

Background

Mould processing product on the current market adopts the mode that the substep is cut to solve the too weak problem of the edge of a knife, increases the mould cost, still is difficult to solve simultaneously fundamentally, and the substep is cut and only can be reduced the cracked frequency of die edge of a knife, solves the weak problem of edge of a knife intensity through the side cut die mold insert that more renews, and waste time and increase manufacturing cost, the utility model patent that the publication is CN 208427628U: split type plate forming die discloses the mould technical scheme that can reduce use cost, still can not solve the too weak problem of mould processing edge of a knife, so people need a difficult cracked mould of edge of a knife to solve the problem that exists among the prior art.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a difficult cracked mould of edge of a knife.

One of the purposes of the utility model is to solve the problem that the die knife edge of the folded bent piece is easy to damage.

The second purpose of the utility model is to enable the die to process and operate the bending angle area close to the workpiece.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a mould that difficult fracture of edge of a knife, includes die, terrace die, die edge of a knife, terrace die edge of a knife, the die below is provided with the die edge of a knife, terrace die top edge is provided with the terrace die edge of a knife, the die edge of a knife vertically corresponds with the horizontal position of terrace die edge of a knife each other, is convenient for do the puncture blanking to the machined part.

The distance between the edge of the male die edge and the side wall of the male die close to the side of the male die edge is 1.5-2 mm, so that the die can puncture the side edge area close to the bending angle of the workpiece.

The die bottom fixed mounting has the locating piece, and the locating piece can transversely be spacing to the machined part, does benefit to the position location efficiency before improving the machined part operation of punctureing.

The female die is in vertical sliding connection with the male die, the female die can be in vertical sliding connection with the male die through the sliding rail sliding grooves, vertical relative movement between the female die and the male die can be achieved, and the purpose of transverse displacement limiting effect is achieved.

The locating piece is vertical length and is less than 10 millimeters locating piece, avoids not blockking by the protruding formation of the edge of blanking to the machined part, influences blanking effect, has improved the adaptability of mould to different machined parts.

The side wall of the side, close to the positioning block, of the male die is inclined from top to bottom in the direction away from the positioning block, so that the side wall of the male die is not attached to a machined part.

Through the technical scheme, the utility model discloses technical scheme's beneficial effect is:

1) when the side wall close to the bending angle is pierced and blanked, the female die knife edge of the existing die is contacted with the bottom of the pierced surface of the machined part, because of the blocking of the side wall thickness of the machined part, the wall thickness of the used female die knife edge cannot be too thick, and the knife edge with thin wall thickness is easy to deform and damage in the blanking process, thereby influencing the effective piercing and blanking of the machined part;

2) the utility model discloses can avoid the lateral wall to have protruding and terrace die laminating of machined part, protruding can extend the machined part with the terrace die laminating and can be punctured the position apart from the shortest distance at the angle of bending, make the machined part can not puncture processing in the suitable position that is close to the angle of bending, protruding and terrace die lateral wall laminating mutually can be avoided in the design of terrace die slope lateral wall on the machined part, make the mould can be close to the lateral wall of the angle department of bending to the machined part and puncture the blanking.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

A die with a knife edge not prone to fracture comprises a female die 101, a male die 102, a female die knife edge 103 and a male die knife edge 104, wherein the female die knife edge 103 is arranged below the female die 101, the male die knife edge 104 is arranged on the upper edge of the male die 102, and the female die knife edge 103 and the male die knife edge 104 are vertically corresponding in transverse position to each other, so that a workpiece 106 can be conveniently punched and punched.

The distance between the edge of the punch edge 104 and the side wall of the punch 102 close to the punch edge 104 is 1.6 mm, so that the die can puncture the side edge region close to the bending angle of the workpiece.

The bottom end of the female die 101 is fixedly provided with a positioning block 107, and the positioning block 107 can transversely limit the workpiece 106, so that the positioning efficiency of the workpiece 106 before piercing operation can be improved.

The female die 101 is vertically and slidably connected with the male die 102, the female die 101 and the male die 102 can be vertically and slidably connected through a sliding rail sliding groove, vertical relative movement between the female die 101 and the male die 102 is achieved, and the purpose of transverse displacement limiting effect is achieved.

The locating piece 107 is 7 millimeters of vertical length's locating piece 107, avoids blockking the protruding formation on the edge that the machined part 106 is not blanked, influences blanking effect, has improved the adaptability of mould to different machined parts.

The side wall of the punch 102 close to the positioning block 107 inclines from top to bottom in the direction far away from the positioning block 107, so that the side wall of the punch 102 is not attached to the workpiece 106, the attachment of the bulge of the side wall of the workpiece with the bulge to the punch 102 is avoided, the shortest distance between the punctured position of the workpiece 106 and the bending angle is lengthened due to the attachment of the bulge to the punch 102, and the workpiece 106 cannot be punctured and processed at the proper position close to the bending angle, the design of the inclined side wall of the punch 102 can avoid the bulge on the workpiece 106 from attaching to the side wall of the punch 102, so that the die can puncture and blank the side wall of the workpiece 106 close to the bending angle, when the side wall close to the bending angle is punctured and blanked, the die edge of the existing die is contacted with the bottom of the punctured surface of the workpiece 106, because the wall thickness of the workpiece 106 is blocked, the wall thickness of the used die edge cannot be too thick, and the thin edge is easy to deform and damage in the blanking process, the influence effectively punctures the blanking to machined part 106, the utility model discloses a mode completion processing that punch edge 104 upwards punctures machined part 106 has solved the problem to die edge of a knife wall thickness restriction.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
