Description
The present invention is application number: 201310266310.3 divisional application, and denomination of invention is: supercharging composite die, application
Day: 2013.06.28.
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.Adopt
With Sheet Metal Forming Technology, there is 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,
Reduce the expense of mould.Meanwhile, there is not mobility it is not necessary to consider that the sealing in hydroforming is asked in rubber
Topic, easy to operate；And rubber can with one-shot forming some complex-shaped parts, such as: non-symmetrical part, wedged bottom part, band office
Part of portion's convex-concave profile etc.；Further, rubber molding also has the advantages that quick response.But, applicant finds in using, and makes
Replace punch (or die) with rubber, because rubber is a continuous elastomer, therefore paste in complex-shaped part forming
Mould is poor, and especially 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 has the characteristics that to transmit non-uniform Distribution internal 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 mould of fast and drip molding total quality.
The supercharging mould 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, described convex
It is formed with the booster cavity for connecting outer liquid force feed input, described die includes concave template and connects die shoe and concave template in mould
Coaming plate, described die shoe, concave template and coaming plate form forming cavity, described concave template are formed with and pass in and out forming cavity for punch
Forming hole, is provided with 0.5mm steel ball layer and rubber layer in described forming cavity, described punch is tight with the one side of punch forming part
Laminating, the another side of described 0.5mm steel ball layer tight punch forming part and 0.5mm steel ball roll located at punch forming
Between part and rubber layer, described rubber layer is filled between shaping chamber inner sidewall and 0.5mm steel ball layer；Described method of work
Including: after punch is to punch forming part punching press laminating, then outer liquid is pressed oil the booster cavity in input punch, to striking out
Type part is 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
Pearl moves to surrounding, and steel ball, in drip molding surface scrolls, changes the stress of material, improves the shaping of punch forming part
Quality.Meanwhile, by the interaction between 0.5mm steel ball layer and rubber layer, in the big local 0.5mm steel of drip molding stress
Pearl layer extrude into rubber layer deeper it is achieved that stress uniform, reduce critical section stress, improve forming limit so that
Drip molding wall thickness is evenly；2) due to being formed with the booster cavity for connecting outer liquid force feed input in punch, injected by outside
Hydraulic 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: is provided with top board in described forming cavity, described top board is located at die shoe and rubber layer
Between, one end of described top board and push rod is fixed.
