Abstract

The invention relates to a stamping die and belongs to the technical field of metal stamping. The stamping die comprises an upper die base and a lower die base which are arranged oppositely. A male die is arranged on the upper die base, and a female die is arranged on the lower die base. A pressing plate for side pressing of a stamping molding part is arranged on the female die, and the female die comprises a female die board and surrounding boards connected with the lower die base and the female die board. The lower die base, the female die board and the surrounding boards form a cavity. A molding hole for the male die to go in and out of the cavity is formed in the female die board, the molding cavity is filled with rubber, the male die is closely attached to one side of the stamping molding part, the rubber tightly covers the other side of the stamping molding part, and steel balls of 0.4mm are closely distributed between the rubber and the stamping molding part and are fixed on the rubber. The stamping mold has the advantages of being fast in stamping pressure response speed and good in whole quality of the molded part.

Description

Diel

Technical field

The present invention relates to a kind of mould, belong to the metal stamping technical field.

Background technology

Punch process in the machining occupies an important position in the processing industry of national economy.The application of sheet metal component is extremely extensive, is deep into manufacturing various aspects, and sheet material forming is mainly realized by diel.Adopt Sheet Metal Forming Technology, have precision height, efficient height, good, the series of advantages such as saving cost, economical with materials and the energy of quality.

Use rubber to replace punch (or die), only need the die (or punch) of a rigidity, simplified mould structure, reduced the expense of mould.Simultaneously, there is not flowability in rubber, does not need to consider the sealing problem in the hydroforming, and is easy to operate; And rubber can some complex-shaped parts of one-shot forming, such as: asymmetric, the part of wedged bottom spare, band Local Convex concave shape etc.; Also have, rubber molding also has the advantage of quick response.But, during using, the applicant finds, use rubber to replace punch (or die), because rubber is a continuous elastomer, so it is poor to paste mould when complex-shaped part forming, especially pastes the mould difference in the roundlet angular position and seem particularly outstanding.

Simultaneously, the applicant finds, in the drawing part, take place in order effectively to reduce forming defects, improve the drip molding surface quality, must apply the attenuate that suitable pressure medium suppresses plate in the forming process, reduce the stress of critical section, improve forming limit, make that the drip molding wall thickness is more even.

Further, the applicant finds that steel ball has can transmit the characteristics of pressing in the non-uniform Distribution.In the forming process, the descending steel ball that forces of punch is to motion all around, and steel ball is mobile on the drip molding surface, has changed the stress of material, has improved the forming quality of drip molding.Therefore, can material be out of shape under best stress condition by regulating the distribution of forming parameters and then adjusting pressure, prevent that the easy weakened section of material from breaking prematurely in forming process, give full play to the plastic deformation performance of material, improve the forming limit of material.

Summary of the invention

The technical problem to be solved in the present invention is at the prior art deficiency, to propose a kind of fast and good diel of drip molding total quality to the stamping pressure response speed.

The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of diel, comprise the upper bolster and the die shoe that are oppositely arranged, described upper bolster is provided with punch, described die shoe is provided with die, described die is provided with the pressing plate for the flanging of punch forming part, described die comprises concave template and the coaming plate that is connected die shoe and concave template, described die shoe, concave template and coaming plate are formed into die cavity, be shaped on the moulding hole for punch turnover forming cavity on the described concave template, be filled with rubber in the described forming cavity, one side of described punch and punch forming part fits tightly, described rubber closely wraps up the another side of punch forming part, be densely covered with the 0.4mm steel ball between described rubber and the punch forming part, described 0.4mm steel ball is fixed on the rubber.

The present invention adopts the beneficial effect of technique scheme to be: because the another side that rubber closely wraps up the punch forming part, be densely covered with the 0.4mm steel ball between rubber and the punch forming part, 0.4mm steel ball is fixed on the rubber, and is fast to the stamping pressure response speed by rubber.On to the fast basis of stamping pressure response speed, by the 0.4mm steel ball is fixed on the rubber, in forming process, the descending steel ball that forces of punch is to motion all around, steel ball is mobile on the drip molding surface, has changed the stress of material, has improved the forming quality of drip molding.Simultaneously, rubber forms the restriction to 0.4mm steel ball motion, has realized stressed evenly reducing the stress of critical section, improves forming limit, makes that the drip molding wall thickness is more even.

Improvement of the technical scheme is: described rubber is the minimum two-layer rubber that sets gradually up and down.

Because rubber is the minimum two-layer rubber that sets gradually up and down, during actual production, can every layer of rubber be made as different pressures according to the different pressures needs of drip molding, can better improve the forming quality of drip molding.

Improvement of the technical scheme is: described die shoe is provided with the push rod that ejects for the punch forming part.

Improvement of the technical scheme is: be provided with top board in the described forming cavity, described top board is between die shoe and rubber, and an end of described top board and push rod is fixed.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of embodiment of the invention diel.
