Description
Technical field
The utility model relates to a kind of mould, belongs to metal stamping technical field.
Background technology
Punch process in 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 supercharging diel.Adopt Sheet Metal Forming Technology, have that precision is high, efficiency is high, quality is good, cost-saving, save the series of advantages such as material 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.Meanwhile, there is not mobility in rubber, do not need to consider the sealing problem in hydroforming, easy to operate; And rubber can some complex-shaped parts of one-shot forming, such as: non-symmetrical part, wedged bottom part, with part of Local Convex concave shape etc.; Also have, rubber molding also has advantages of quick response.But, during using, 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, especially at small round corner position, paste that mould is poor seems particularly outstanding.
Meanwhile, applicant finds, in stamping, in order effectively to reduce forming defects, occur, improve drip molding surface quality, in forming process, must apply the attenuate that suitable pressure medium suppresses plate, reduce the stress of critical section, improve forming limit, make drip molding wall thickness more even.
Further, applicant's discovery, steel ball has can transmit the feature of pressing in non-uniform Distribution.In forming process, the descending steel ball that forces of punch moves to surrounding, and steel ball is mobile on 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.
Meanwhile, applicant finds, by the supercharging to punch, on the basis of existing forcing press, can further improve the pressure to profiled member, simultaneously, profiled member for the first time on stamping basis, is being carried out to secondary pressurized to profiled member, can effectively prevent the resilience of profiled member.
Utility model content
The technical problems to be solved in the utility model is, for 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 utility model 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, in described punch, be shaped with for connecting the booster cavity of outer liquid force feed input, 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, on described concave template, be shaped with the forming hole for punch turnover forming cavity, in described forming cavity, be filled with rubber, one side of described punch and punch forming part fits tightly, described rubber closely wraps up the another side of punch forming part, between described rubber and punch forming part, be densely covered with 0.4mm steel ball, described 0.4mm steel ball is fixed on rubber.
The utility model adopts the beneficial effect of technique scheme to be: the another side of 1) closely wrapping up punch forming part due to rubber, between rubber and punch forming part, be densely covered with 0.4mm steel ball, 0.4mm steel ball is fixed on rubber, by rubber to stamping pressure fast response time.On to the basis of stamping pressure fast response time, by 0.4mm steel ball is fixed on rubber, in forming process, the descending steel ball that forces of punch moves to surrounding, steel ball is mobile on drip molding surface, has changed the stress of material, has improved the forming quality of drip molding.Meanwhile, rubber forms the restriction to 0.4mm steel ball motion, has realized stressed evenly reducing the stress of critical section, improves forming limit, makes drip molding wall thickness more even; 2) owing to being shaped with in punch for connecting the booster cavity of outer liquid force feed input, by outside injection liquid force feed, realize the secondary booster to punch forming part, better improved the quality of punch forming part.
The improvement of technique scheme is: described rubber is the minimum two-layer rubber setting gradually up and down.
Because rubber is the minimum two-layer rubber setting gradually up and down, during actual production, can every layer of rubber be made as to different pressures according to the different pressures needs of drip molding, can better improve the forming quality of drip molding.
The improvement of technique scheme is: described die shoe is provided with the push rod ejecting for punch forming part.
The improvement of technique scheme is: in described forming cavity, be provided with top board, described top board is between die shoe and rubber, and one end of described top board and push rod is fixed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment supercharging diel.
