Abstract

The invention discloses a kind of impact forming method for improving thick material product euphotic belt, comprise the following steps:S1, coordinated using the first punch-pin and cavity plate and product slightly rushed, the first punch-pin punching press to product thickness 2/3 3/4 when, stop slightly rushing, recall the first punch-pin, the blade clearance between the first punch-pin and cavity plate is product(3)The 1% of thickness;S2, using the second punch-pin continue in step S1 product carry out fine, product is separated with waste material, the blade clearance between the second punch-pin and cavity plate is product(3)The 0.25% of thickness.The beneficial effects of the invention are as follows:The brightness in section caused by punch forming can be made to reach more than the 90% of product thickness, i.e., need not again be mechanically polished or chemical polishing can just obtain smooth section, so as to save processing cost, improved processing efficiency, also reduce difficulty of processing.

Description

A kind of impact forming method for improving thick material product euphotic belt

Technical field

The present invention relates to punch forming technical field, particularly a kind of punch forming side for improving thick material product euphotic belt Method.

Background technology

Punch forming refers to that depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., is allowed to produce plasticity change Shape or separation, so as to obtain the workpiece of required shape and size(Stamping parts)Processing molding method.The blank of punching press is mainly Hot rolling and the steel plate and steel band of cold rolling.The part of conventional ones shaping, the plane of disruption overwhelming majority is roughness profile, and some parts It is required that the plane of disruption need to be shiny surface, thus the product obtained by punch forming also needs to throw by mechanical polishing or chemistry Light can just access shiny surface, and time and effort consuming, processing efficiency is low, high processing costs.

The content of the invention

A kind of the shortcomings that it is an object of the invention to overcome prior art, there is provided punch forming side for improving thick material product euphotic belt Method.

The purpose of the present invention is achieved through the following technical solutions:A kind of punch forming side for improving thick material product euphotic belt Method, comprise the following steps:

S1, coordinated using the first punch-pin and cavity plate and product is slightly rushed, the 2/3-3/4 of the first punch-pin punching press to product thickness When, stop thick punching, recall the first punch-pin, the blade clearance between the first punch-pin and cavity plate is the 1% of product thickness;

S2, using the second punch-pin continue in step S1 product carry out fine, product is separated with waste material, the second punch-pin with it is recessed The blade clearance of intermode is the 0.25% of product thickness.

The present invention has advantages below:

The present invention can make the brightness in section caused by punch forming reach more than the 90% of product thickness, i.e., need not enter again Row mechanical polishing or chemical polishing can just obtain smooth section, so as to save processing cost, improve processing efficiency, Reduce difficulty of processing.

Brief description of the drawings

Fig. 1 is the structural representation when present invention carries out step S1.

Fig. 2 is the structural representation when present invention carries out step S2.

In figure, the punch-pin of 1- first, 2- cavity plates, 3- products, the punch-pin of 4- second.

Embodiment

The present invention will be further described below in conjunction with the accompanying drawings:

A kind of impact forming method for improving thick material product euphotic belt, comprises the following steps:

S1, coordinated using the first punch-pin 1 with cavity plate 2 and product 3 is slightly rushed, the 2/3- of the punching press of the first punch-pin 1 to the thickness of product 3 When 3/4, as shown in figure 1, stopping thick punching, the first punch-pin 1 is recalled, the blade clearance between the first punch-pin 1 and cavity plate 2 is that product 3 is thick The 1% of degree;

S2, continue using the second punch-pin 4 to carry out fine to the product 3 in step S1, as shown in Fig. 2 making product 3 and waste material point From the blade clearance between the second punch-pin 4 and cavity plate 2 is the 0.25% of the thickness of product 3.

The present invention can make the brightness in section caused by punch forming reach more than the 90% of the thickness of product 3, i.e., need not Mechanically polished again or chemical polishing can just obtain smooth section, so as to save processing cost, improve processing effect Rate, also reduce difficulty of processing.
