Description
The application is divisional application, the application number of original application: 2013102663103, the applying date: 2013-6-28, invention name Claim: 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 Field is extremely extensive, is deep into manufacturing various aspects, and sheet material forming is mainly realized by diel.Use presser Skill, has 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, fall The low 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, band Local Convex concave shape Part etc.；Further, the advantage that rubber molding also has quickly response.But, applicant finds in using, and uses rubber to replace convex Mould (or die), owing to rubber is a continuous print elastomer, therefore paste mould when complex-shaped part forming poor, especially At small round corner position, patch mould difference seems especially prominent.
Meanwhile, it has been found that in stamping part, occur to effectively reduce forming defects, improve drip molding table Face quality, must apply suitable pressure medium to suppress the thinning of plate in forming process, reduce the stress of critical section, carry High 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, convex Mould is descending forces steel ball to move to surrounding, and steel ball, at drip molding surface scrolls, changes the stress of material, improves shaping The forming quality of part.Therefore, it can, by regulation forming parameters and then the distribution of regulation pressure, make material best Deform under stress condition, prevent the easy weakened section of material from rupturing prematurely 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, on the basis of the most stamping to profiled member, adds profiled member is carried out secondary meanwhile Pressure, 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 to stamping pressure response speed Fast and that drip molding total quality is good supercharging composite die.
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 shaped with in described punch For connecting the booster cavity of outer liquid force feed input, 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, and described concave template is shaped with the forming hole for punch turnover forming cavity, Being provided with 0.5mm steel ball layer and rubber layer in described forming cavity, described punch fits 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 is located at punch forming part and rubber layer Between, described rubber layer is filled between forming cavity medial wall and 0.5mm steel ball layer；Described method of work includes: at punch After punch forming part punching press is fitted, then by the booster cavity in outer liquid force feed input punch, punch forming part is entered one The extruding of step.
The present invention uses technique scheme to provide the benefit that: 1) due to 0.5mm steel ball layer tight punch forming The another side of part and 0.5mm steel ball roll to be 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 forces steel ball Moving to surrounding, steel ball at 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, at the local 0.5mm steel ball layer that drip molding stress is big Extrude the deepest in rubber layer, it is achieved that stress uniform, reduce the stress of critical section, improve forming limit so that shape Part wall thickness is evenly；2) owing to being shaped with the booster cavity for connecting the input of outer liquid force feed in punch, hydraulic pressure is injected by outside 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 set gradually up and down.
Owing to rubber layer is the minimum two-layer rubber layer set gradually up and down, during actual production, can be according to drip molding Different pressures needs, 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 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 positioned at die shoe and rubber layer Between, one end of described top board and push rod is fixed.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention supercharging composite die.
Detailed description of the invention
The supercharging composite die of the present embodiment, as it is shown in figure 1, include upper bolster 1 and the die shoe 2 being oppositely arranged.Upper mold Seat 1 is provided with punch 3, and die shoe 2 is provided with die 4.Die 4 is provided with the pressing plate 6 for punch forming part 5 flanging.
The booster cavity 3-1 for connecting the input of outer liquid force feed it is shaped with in punch 3.Die 4 includes concave template 4-1 and connection The coaming plate 4-2 of die shoe 2 and concave template 4-1.Die shoe 2, concave template 4-1 and coaming plate 4-2 form forming cavity.On concave template 4-1 It is shaped with the forming hole passing in and out forming cavity for punch 3.0.5mm steel ball layer 4-3 and rubber layer 4-4 it is provided with in forming cavity.
Punch 3 fits tightly with the one side of punch forming part 5,0.5mm steel ball layer 4-3 tight punch forming part 5 Another side and 0.5mm steel ball roll be located between punch forming part 5 and rubber layer 4-4.Rubber layer 4-4 is filled in forming cavity Between medial wall and 0.5mm steel ball layer 4-3.
The rubber layer 4-4 of the present embodiment is the minimum two-layer rubber layer set gradually up and down.
The die shoe 2 of the present embodiment is provided with the push rod 7 ejected for punch forming part 5.
Top board 8 it is provided with in the forming cavity of the present embodiment.Top board 8 between die shoe 2 and rubber layer 4-4, top board 8 and top One end of bar 7 is fixed.
During use, after punch forming part 5 punching press is fitted by punch 3, then by the supercharging in outer liquid force feed input punch 3 Chamber 3-1, is further extruded punch forming part 5.
