Abstract

The invention discloses a precise stamping die realizing rapid displacement of a knife edge. The precise stamping die comprises an upper cover plate, an upper die holder, an upper backing plate, an upper clamp plate, a back stripping plate, a stripper plate, a lower template, a lower backing plate and a lower die holder which are fixedly connected in turn; a split knife edge is fixed in the lower template; and the precise stamping die is characterized in that: the two sides of the split knife edge are provided with split knife edge adjusting blocks. The die disclosed by the invention effectively solves the problems that the punching knife edge is frequently maintained and the production time is occupied in the production process of a stamping die, can remarkably improve the production efficiency, ensures stable production of products, is convenient to operate and quick to maintain, and has strong practicability.

Description

A kind of edge of a knife rapid traverse precise punching die

Technical field

The present invention relates to a kind of edge of a knife rapid traverse precise punching die.

Background technology

Rise day by day in the status of mould industry in national economy; Mould is industrial fundamental technology equipment; In products such as electronics, automobile, motor, electrical equipment, instrument, household electrical appliances and communication, 60% ~ 80% parts all are to rely on die forming, and the height of die quality directly determines the height of product quality; Therefore, mould is called as " mothers of all trades ".Mould is again " a benefit amplifier ", with the value of the final products of die production often the mould self-value tens, hundreds of times.

The employed mould of punching press is called diel, is called for short punch die.Punch die is that the material batch machining is become required specific purpose tool towards part.The maximum function of mould is exactly to improve production efficiency of products greatly and stable quality guarantee is provided; Certainly; Accurate again mould still needs repairing in actual production and maintains; The efficient that the raising mould keeps in repair in process of production seems particularly important under the multiple pressure of market competition and raw material rise in price!

In the telecommunications industry; There are a lot of high-precision products very strict to tolerance; In order to guarantee the product precision, the die-cut edge of a knife of a lot of moulds generally can adopt wolfram steel class material to process, and it often needs aborning, and grinding is shifted to wait adjusts product size; The maintenance of the die-cut edge of a knife is frequent in process of production to cause diel, takies long problem of production time.

Traditional structure often adopts the edge of a knife part split structure among Fig. 1; Edge of a knife putty when preventing to produce; When in the production process because problems such as product burr, change in size need carry out the edge of a knife displacement time; Because traditional edge of a knife is the branch body structure, so in operating process, a lot of problems can occur: grind difficulty, loss emery wheel like wolfram steel class material; Edge of a knife gap, displacement back is wayward; Need to increase pad after the displacement and be unfavorable for assembling, the significant wastage human and material resources influences production efficiency.

Summary of the invention

Goal of the invention is to propose a kind of edge of a knife rapid traverse precise punching die, in order to improve the diel drawing velocity of mould and the stability of product quality aborning, further enhances productivity, and reduces the mold repair frequency.

Technical scheme: for solving the problems of the technologies described above; A kind of edge of a knife rapid traverse precise punching die that the present invention proposes; Comprise that the upper cover plate, upper bolster, upper padding plate, train wheel bridge, the back of the body that are fixedly connected sequentially take off plate, stripper plate, lower bolster, lower bolster, die shoe; The split edge of a knife is fixed in the lower bolster, it is characterized in that: be provided with split edge of a knife adjustment piece in described split edge of a knife both sides.

Described split edge of a knife adjustment piece adopts white steel to process.

Beneficial effect: a kind of edge of a knife rapid traverse precise punching die of proposition of the present invention; The maintenance of the die-cut edge of a knife is frequent in process of production effectively to solve diel; Take the problem of production time; Can greatly enhance productivity, guarantee the product steady production, easy to operate, maintenance is convenient, practical.

Description of drawings

Fig. 1 is a conventional knives mouth structure sketch map;

Fig. 2 is an edge of a knife structural representation of the present invention;

Fig. 3 is a die opening state sketch map of the present invention;

Fig. 4 is a matched moulds view of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done explanation further.

Like Fig. 3, shown in Figure 4; The present invention includes the upper cover plate 1 that is fixedly connected sequentially, upper bolster 2, upper padding plate 3, train wheel bridge 4, the back of the body takes off plate 5, stripper plate 6, lower bolster 7, lower bolster 8, die shoe 9, the split edge of a knife 10 and is fixed in the lower bolster 7; As shown in Figure 2; Be provided with split edge of a knife adjustment piece 11 in the described split edge of a knife 10 both sides, described split edge of a knife adjustment piece 11 adopts white steel to process.

Like this, when in the production process because problems such as product burr, change in size need carry out the edge of a knife displacement time, we just can be directly adjust piece 11 to the split edge of a knife and take out separately and grind adjustment.Split edge of a knife adjustment piece 11 after good is installed in the lump with the former edge of a knife 10 and gone back mill again, has solved edge of a knife displacement problem fast, need not carry out grinding step to the original edge of a knife, and is better, the operation that is shifted of the completion edge of a knife faster!

The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.

Claims

1. edge of a knife rapid traverse precise punching die; Comprise that the upper cover plate (1) that is fixedly connected sequentially, upper bolster (2), upper padding plate (3), train wheel bridge (4), the back of the body take off plate (5), stripper plate (6), lower bolster (7), lower bolster (8), die shoe (9), the split edge of a knife (10) and be fixed in the lower bolster (7), it is characterized in that: be provided with split edge of a knife adjustment piece (11) in the described split edge of a knife (10) both sides.
