Abstract

The utility model provides an integral die with good punching effect, comprising a die seat. The integral die with good punching effect is characterized in that the slot in a die base is in parallel provided with at least two first dies, at least one second die and two die baffle blocks so as to let the first dies and the second die to form an integral body; the second die is clamped between the two first dies; the two sides of the first dies and the second die are fixed by the die baffle blocks; the tops and the bottoms of the first dies and the second die are separately provided with die locating blocks for fixing the positions of the dies; and the first dies, the second die and the die baffle blocks are pressed by die press bars. The integral die with good punching effect is advantaged by improving the tensile strength of steel belt product and improving the product quality.

Description

The whole die that a kind of punching press is effective

Technical field

The utility model relates to the whole die that a kind of die knife-edge part does not have the envelope of connecing, and is used for the die part of automobile band steel mold, belongs to technical field of mold.

Background technology

In the automobile steel carries product, since the automobile steel carries product to the requirement of strength of the impression vestige on its surface and stretching than higher, its general die edge is pieced together structure as shown in Figure 1, is made up of die socket 1, die locating piece 2, die block 3, die press strip 4, first die 5 and second die 6.Because the steel band product needed is pressed close to the die face, and has the patrix unloading block to compress, punch could be gone out required steel band product downwards.The edge of a knife of die part is spliced to form by first die 5 and 6 two dies of second die, so in the mould use, the die edge of a knife that is combined into first die 5 and second die 6 connects the muscle place at it and can form a piece.Because it is inconsistent that stressed inequality makes the bottom surface wearing and tearing of die socket 1 in the process that mould uses, first die 5 and second die 6 that make will form difference in height on die socket.Connect the muscle place at steel band when die-cut and will form an impression step, influence the quality of steel strip surface.The muscle that the while steel band connects the muscle place is very thin, and product just is easy to break after forming the impression step.This just needs a kind of good edge of a knife edge assembly mode, to improve the quality of steel band product.

Summary of the invention

The purpose of this utility model provides a kind of raising steel band product surface quality, and the whole die edge that increases the product hot strength is pieced together structure.

In order to achieve the above object, the technical solution of the utility model has provided the effective die of a kind of punching press, comprise die socket, it is characterized in that: in the groove of die socket, be provided with at least two first dies side by side, thereby at least one second die and two die blocks make win die and integral body of second die formation, second die is clipped between two first dies, the both sides of first die and second die are fixed by the die block, top and bottom at first die and second die are respectively equipped with the die locating piece of fixing its position, push down first die by the die press strip, second die and die block.

The utility model is the die edge of a knife of first die and an integral body of second die formation, and the piece between die can not occur at the company muscle place of the edge of a knife.During punching press, die edge spell shape becomes also can not have influence on the surface and the hot strength of steel band product when being sewn on die and being uneven, more guaranteed to the quality of product like this.

This shows, the utility model has the advantages that the hot strength that can improve the steel band product, improve the quality of products.

Fig. 1 is former die schematic diagram;

The die schematic diagram that a kind of punching press that Fig. 2 provides for the utility model is effective.

The specific embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

As shown in Figure 2, the utility model provides a kind of punching press effective whole die, is made up of die socket 1, die locating piece 2, die block 3, die press strip 4, first die 5, second die 6.Piece together side by side with five first dies 5, four second dies 6 and two die blocks 3 and to go into the position of fixing first die 5 and second die 6 in die socket 1 groove by the groove of die locating piece 2, and on die locating piece 2 and die socket 1, join and cut pin hole to fix the position of die.Push down first die 5, second die 6 and die block 3 with die press strip 4.

During work, unloading block is pressed in edge and pieces together good die part, and die mold insert piece is or not the company muscle place of steel band product, effectively the impression of the company's of removal muscle.

Claims (1)

1. whole die that punching press is effective, comprise die socket (1), it is characterized in that: in the groove of die socket (1), be provided with at least two first dies (5) side by side, at least one second die (6) and two die blocks (3) thus make the die of winning (5) and second die (6) forms an integral body, second die (6) is clipped between two first dies (5), the both sides of first die (5) and second die (6) are fixing by die block (3), top and bottom at first die (5) and second die (6) are respectively equipped with the die locating piece (2) of fixing its position, push down first die (5) by die press strip (4), second die (6) and die block (3).
