Description
Technical field
The present invention relates to a kind of mould, belong to metal stamping techniques 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, and be deep into manufacturing various aspects, sheet material forming realizes mainly through 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, simplify mould structure, reduce 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: the part etc. of non-symmetrical part, wedged bottom part, band Local Convex concave shape; Further, rubber molding also has the advantage of response fast.But find during applicant uses, use rubber to replace punch (or die), because rubber is a continuous print elastomer, therefore paste mould when complex-shaped part forming poor, especially pastes mould difference at small round corner position and seem particularly outstanding.
Meanwhile, applicant finds, in stamping, occurring to effectively reduce forming defects, improving drip molding surface quality, suitable pressure medium must be applied in forming process to suppress the thinning of plate, reduce the stress of critical section, improve forming limit, make drip molding wall thickness evenly.
Further, applicant finds, steel ball has the advantages that to transmit pressure 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, changes the stress of material, improves the forming quality of drip molding.Therefore, by regulating the distribution of forming parameters and then adjustment pressure, material can be out of shape under best stress condition, prevent 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, further can improve the pressure to profiled member, simultaneously, on the basis stamping to profiled member first time, secondary pressurized is being carried out to profiled member, effectively can prevent the resilience of profiled member.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of to stamping pressure fast response time and the good supercharging diel of drip molding total quality.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of supercharging diel, comprise the upper bolster and 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 striking out shaped piece flanging, the booster cavity for connecting the input of outer liquid force feed is shaped with in described punch, described die comprises concave template and the coaming plate being connected die shoe and concave template, described die shoe, concave template and coaming plate are formed into die cavity, described concave template is shaped with the forming hole for punch turnover forming cavity, rubber is filled with in described forming cavity, described punch fits tightly with the side striking out shaped piece, described rubber closely wraps up the another side striking out shaped piece, described rubber and strike out between shaped piece and be densely covered with 0.4mm steel ball, described 0.4mm steel ball is fixed on rubber.
The present invention adopts the beneficial effect of technique scheme to be: 1) because rubber closely wraps up the another side striking out shaped piece, rubber and strike out between shaped piece and 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 the basis to 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, changes the stress of material, improves the forming quality of drip molding.Meanwhile, rubber forms the restriction to the motion of 0.4mm steel ball, achieves stressed even, reduces the stress of critical section, improve forming limit, make drip molding wall thickness evenly; 2) owing to being shaped with the booster cavity for connecting the input of outer liquid force feed in punch, by outside injection liquid force feed, but realizing the secondary booster to punch forming part, better improve the quality striking out shaped piece.
The improvement of technique scheme is: described rubber is the minimum two-layer rubber set gradually up and down.
Because rubber is the minimum two-layer rubber set gradually up and down, during actual production, according to the different pressures needs of drip molding, every layer of rubber can be set to different pressures, better can improve the forming quality of drip molding.
The improvement of technique scheme is: described die shoe is provided with the push rod ejected for striking out shaped piece.
The improvement of technique scheme is: be provided with top board in described forming cavity, and described top board is between die shoe and rubber, and one end of described top board and push rod is fixed.
