Description

A kind of method of work of mould
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 Field is extremely extensive, is deep into manufacturing various aspects, and sheet material forming is mainly realized by diel.Using presser Skill, has high precision, efficiency high, quality is good, cost-effective, save the series of advantages such as material and the energy.
Replace punch (or die) using rubber, only need the die (or punch) of a rigidity, simplify mould structure, fall The low expense of mould.Meanwhile, there is not mobility it is not necessary to consider the sealing problem in hydroforming in rubber, easy to operate； And rubber can with one-shot forming some complex-shaped parts, such as:Non-symmetrical part, wedged bottom part, with local convex-concave profile Part etc.；Further, rubber molding also has the advantages that quick response.But, applicant finds in using, and is replaced convex using rubber Mould (or die), because rubber is a continuous elastomer, therefore patch mould is poor, especially in complex-shaped part forming In roundlet angular position, patch mould difference seems especially prominent.
Meanwhile, it has been found that in stamping part, occurring to effectively reduce forming defects, improving drip molding table Face quality, must apply suitable pressure medium to suppress the thinning of plate, reduce the stress of critical section, carry in forming process High forming limit so that drip molding wall thickness evenly.
Further, it has been found that steel ball have the characteristics that to transmit non-uniform Distribution intrinsic pressure.In forming process, convex Mould is descending to force steel ball to move to surrounding, and steel ball, in drip molding surface scrolls, changes the stress of material, improves shaping The forming quality of part.Therefore, it can the distribution by adjusting forming parameters and then regulation pressure, make material best Deform under stress condition, prevent the easy weakened section of material from prematurely rupturing in forming process, give full play to moulding of material Property deformation performance, improve material forming limit.
Meanwhile, it has been found that by the supercharging to punch, on the basis of existing forcing press, can further carry The high pressure to profiled member, meanwhile, on the basis of stamping for the first time to profiled member, is carrying out secondary adding to profiled member Pressure, can effectively prevent the resilience of profiled member.
Content of the invention
The technical problem to be solved in the present invention is, not enough for prior art, propose a kind of to stamping pressure response speed The method of work of the good supercharging composite die of fast and drip molding total quality.
The supercharging composite die of the present invention, including the upper bolster being oppositely arranged and die shoe, described upper bolster is provided with convex Mould, described die shoe is provided with die, and described die is provided with the pressing plate for punch forming part flanging, is formed with described punch For connecting the booster cavity of outer liquid force feed input, described die includes the coaming plate of concave template and connection die shoe and concave template, Described die shoe, concave template and coaming plate form forming cavity, and described concave template is formed with the forming hole passing in and out forming cavity for punch, Described molding intracavity is provided with 0.5mm steel ball layer and rubber layer, and described punch is fitted tightly with the one side of punch forming part, described The another side of 0.5mm steel ball layer tight punch forming part and 0.5mm steel ball roll located at punch forming part and rubber layer Between, described rubber layer is filled between molding chamber inner sidewall and 0.5mm steel ball layer.Described method of work includes：Use When, after punch is to punch forming part punching press laminating, then outer liquid is pressed oil the booster cavity in input punch, to punch forming part Further extruded.
The present invention using the beneficial effect of technique scheme is：1）Due to 0.5mm steel ball layer tight punch forming The another side of part and 0.5mm steel ball roll located between punch forming part and rubber layer, and rubber layer is filled in inside forming cavity Between wall and 0.5mm steel ball layer, by rubber layer, to stamping pressure fast response time.To stamping pressure fast response time On the basis of, by having 0.5mm steel ball layer, by the steel ball of 0.5mm size, in forming process, punch is descending to force steel ball Move to surrounding, steel ball, in drip molding surface scrolls, changes the stress of material, improves the morphoplasm of punch forming part Amount.Meanwhile, by the interaction between 0.5mm steel ball layer and rubber layer, in the big local 0.5mm steel ball layer of drip molding stress Extrude into rubber layer deeper it is achieved that stress uniform, reduce critical section stress, improve forming limit so that shape Part wall thickness is evenly；2）Due to being formed with the booster cavity for connecting outer liquid force feed input in punch, by outside injection hydraulic pressure Oil, 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 setting gradually up and down.
Because rubber layer is the minimum two-layer rubber layer setting gradually up and down, during actual production, can be according to drip molding Different pressures need, and every layer of rubber layer is 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 for the ejection of punch forming part.
The improvement of technique scheme is：Described molding intracavity is provided with top board, and described top board is located at die shoe and rubber layer Between, one end of described top board and push rod is fixed.
