Description
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 the supercharging diel.Adopt Sheet Metal Forming Technology, have that precision is high, efficient is high, quality is good, save the series of advantages such as cost, economical with materials and the energy.
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: non-symmetrical part, wedged bottom spare, with part of Local Convex concave shape etc.; Also have, rubber molding also has advantages of quick response.But, during using, the applicant finds, use rubber to replace punch (or die), because rubber is a continuous elastomer, therefore it is poor to paste mould when complex-shaped part forming, paste at the small round corner position especially that mould is poor to seem particularly outstanding.
Simultaneously, the applicant finds, in stamping, occur 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, so that the drip molding wall thickness is more even.
Further, applicant's discovery, 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.
Simultaneously, the applicant finds, by the supercharging to punch, on the basis of existing forcing press, can further improve the pressure to profiled member, simultaneously, on to for the first time stamping basis of profiled member, profiled member is being carried out secondary pressurized, can effectively prevent the resilience of profiled member.
Summary of the invention
The technical problem to be solved in the present invention is for the prior art deficiency, to propose a kind of to stamping pressure fast response time and the good supercharging diel of drip molding total quality.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of supercharging 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, be shaped with in the described punch for the booster cavity that connects the input of outer liquid force feed, 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 with the forming 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: 1) 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, by rubber to the stamping pressure fast response time.On the basis to the stamping pressure fast response time, 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, so that the drip molding wall thickness is more even; 2) owing to being shaped with in the punch for the booster cavity that connects the input of outer liquid force feed, by outside injection liquid force feed, realize the secondary booster to the punch forming part, better improved the quality of punch forming part.
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.
