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 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 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.
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 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 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, 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: 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.
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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of embodiment of the present invention diel.
Detailed description of the invention
