Description

A kind of mould
The application is divisional application, the application number 2013102663103 of original application, the applying date: on June 28th, 2013, invention and created name: supercharging composite die.
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, is deep into manufacturing various aspects, and sheet material forming is mainly realized by diel.Use Sheet Metal Forming Technology, have that precision is high, efficiency high, quality is good, cost-effective, 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, it is not necessary to considers the sealing problem in hydroforming, easy to operate；And rubber can be with some complex-shaped parts of one-shot forming, such as: non-symmetrical part, wedged bottom part, the part etc. of band Local Convex concave shape；Further, the advantage that rubber molding also has quickly response.But, applicant finds in using, and uses rubber to replace punch (or die), and owing to rubber is a continuous print elastomer, therefore paste mould when complex-shaped part forming poor, especially seems especially prominent in small round corner position patch mould difference.
Meanwhile, it has been found that in stamping part, occur to effectively reduce forming defects, improve drip molding surface quality, forming process must apply suitable pressure medium to suppress the thinning of plate, reduce the stress of critical section, improve forming limit so that drip molding wall thickness is evenly.
Further, it has been found that steel ball has can transmit the feature that non-uniform Distribution is intrinsic pressure.In forming process, punch is descending forces steel ball to move to surrounding, and steel ball at drip molding surface scrolls, changes the stress of material, improves the forming quality of drip molding.Therefore, material can be made to deform under best stress condition by regulation forming parameters and then the distribution of regulation pressure, prevents the easy weakened section of material from rupturing prematurely in forming process, give full play to the plastic deformation performance of material, improve the forming limit of material.
Meanwhile, it has been found that by the supercharging to punch, on the basis of existing forcing press, can further improve the pressure to profiled member, simultaneously, on the basis of the most stamping to profiled member, profiled member 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, not enough for prior art, proposes a kind of supercharging composite die good to stamping pressure fast response time and drip molding total quality.
nullThe present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of supercharging composite die，Including the upper bolster being oppositely arranged and die shoe，Described upper bolster is provided with punch，Described die shoe is provided with die，Described die is provided with the pressing plate for punch forming part flanging，The booster cavity for connecting the input of outer liquid force feed it is shaped with in described punch，Described die includes concave template and connects the coaming plate of die shoe and concave template，Described die shoe、Concave template and coaming plate form forming cavity，The forming hole for punch turnover forming cavity it is shaped with on described concave template，0.5mm steel ball layer and rubber layer it is provided with in described forming cavity，Described punch fits tightly with the one side of punch forming part，The another side of described 0.5mm steel ball layer tight punch forming part and 0.5mm steel ball roll to be located between punch forming part and rubber layer，Described rubber layer is filled between forming cavity medial wall and 0.5mm steel ball layer.
The present invention uses technique scheme to provide the benefit that: 1) owing to another side and the 0.5mm steel ball of 0.5mm steel ball layer tight punch forming part roll and be located between punch forming part and rubber layer, rubber layer is filled between forming cavity medial wall and 0.5mm steel ball layer, by rubber layer, to stamping pressure fast response time.On the basis of to stamping pressure fast response time, by having 0.5mm steel ball layer, by the steel ball of 0.5mm size, in forming process, punch is descending forces steel ball to move to surrounding, and steel ball is at drip molding surface scrolls, change the stress of material, improve the forming quality of punch forming part.Meanwhile, by the interaction between 0.5mm steel ball layer and rubber layer, the local 0.5mm steel ball layer big in drip molding stress extrudes the deepest in rubber layer, achieve the uniform of stress, reduce the stress of critical section, improve forming limit so that drip molding wall thickness is evenly；2) owing to being shaped with the booster cavity for connecting the input of outer liquid force feed in punch, inject hydraulic oil by outside, but realize the secondary booster to punch forming part, preferably improve the quality of punch forming part.
The improvement of technique scheme is: described rubber layer is the minimum two-layer rubber layer set gradually up and down.
Owing to rubber layer is the minimum two-layer rubber layer set gradually up and down, during actual production, according to the different pressures needs of drip molding, every layer of rubber layer can be set to different pressures, can preferably improve the forming quality of drip molding.
The improvement of technique scheme is: described die shoe is provided with the push rod ejected for punch forming part.
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 layer, and one end of described top board and push rod is fixed.
The method of work of described supercharging composite die, including: after punch forming part punching press is fitted by punch, then by the booster cavity in outer liquid force feed input punch, punch forming part is further extruded.
Accompanying drawing explanation
