Abstract

The present invention relates to the diel field, particularly be to realize drawing the process and the mould of flange moulding in the diel.This method will draw that moulding combines with flange, in punching course, part done according to having Z-shaped flange moulding of binder up and down, and drawing and moulding is on holding pad under the flange, and part material in forming process is pushed down always.Thereby slowed down the speed that material flows into, solved wrinkling, the folded material phenomenon of part.

Description

A kind of process and mould thereof that draws the flange moulding
Technical field
The present invention relates to the diel field, particularly be to realize drawing the process and the mould of flange moulding in the diel.
Background technology
In recent years, along with the automobile industry develop rapidly, the die industry competition is fierce more; In view of the increasing situation of cost pressure, change traditional Sheet Metal Forming Technology, reduce the usage quantity of stamping procedure and lathe; Practice thrift cost, become the necessary Consideration of mould design.
Drawing is the stamping procedure that becomes plane woolen cloth or operation part curve form, and curved surface mainly relies on and is positioned at extending to form of punch base material.For the drawing work of complicated shape spare, automobile tail light fixed head for example, part sidewall height is very high, and the folded material in sidewall bottom surface is serious, the forming parts difficulty.Through the test of many times analysis, utilize traditional drawing work part to be difficult to moulding.Therefore, a kind of method of exigence addresses the above problem on the basis that does not increase the mould operation.
Summary of the invention
The object of the present invention is to provide a kind of process of drawing the flange moulding, this method can address the above problem under the situation that does not increase mould operation, press machine.
Concrete technical scheme is following:
A kind of process of drawing the flange moulding; This method will draw that moulding combines with flange, in punching course, part done according to having Z-shaped flange moulding of binder up and down; Drawing and moulding is on holding pad under the flange; Part material in forming process is pushed down always, thereby has slowed down the speed that material flows into, and has solved wrinkling, the folded material phenomenon of part.
Further, said part begins flanging process after drawing completion, and the top and bottom of part sidewall are pushed down always, finishes until flange.
Further, in the said turn-up process, be provided with step surface and bead above the part sidewall, slow down its flowing velocity in turn-up process, solved folded material, wrinkling.
Further, in the said drawing process,, on the product press surface, bead is set for the ease of adjusting the speed that flows of its material.
Further, in the above-mentioned process two symmetrical components are made together, or solved under the situation of its side force, suitable equally to single part.
Another object of the present invention provides a kind of mould that is exclusively used in said method.
A kind of mould that is used to draw the flange moulding technique; This mould comprises upper bolster 1, die 3, goes up holding pad 2, die shoe 6, flanging die 4, blank holder 7, draws punch 5 and punch retainer 8; Wherein said punch 5 and the blank holder 7 of drawing continues motion as the holding pad of flange and finishes until flange after drawing end; Said die 3 is as the die of drawing work content and the die of flanging process content.
Further, in said drawing process, draw punch 5 and be movable pattern with punch retainer 8.
Further, pressure source is the push rod 9 of lathe, draws punch 5, blank holder 7 and punch retainer 8 at first at flange and under the thrust of push rod 9, begins flange.This pressure source also can be nitrogen spring 10, and its initial pressure is greater than pressure-pad-force and drawing pressure.
Further, die 3 is as the die of drawing work content and the flange die of flanging process content, and in turn-up process, the flanging die 4 that is arranged on the die shoe 6 turns over material on die 3.
Further, in said drawing process, blank holder 7 is as the parts of in drawing work, pushing down material, and its pressure source is the nitrogen spring 10 that is installed in the punch retainer 8.
The invention has the beneficial effects as follows: utilize above-mentioned process,, slowed down the speed that material flows into, can under the situation that does not increase mould operation, press machine, solve wrinkling, the folded material phenomenon of part because part material in forming process is pushed down always.
Description of drawings
Fig. 1 is the schematic diagram of process of the present invention
Fig. 2 is the A-A cutaway view of mould of the present invention
Fig. 3 is the B-B cutaway view of mould of the present invention
Among the figure: 1. holding pad 3. dies 4. flanging dies 5. draw punch 6. die shoes 7. blank holders 8. punch retainers 9. push rods 10. nitrogen springs on the upper bolster 2..
The specific embodiment
Specify principle of the present invention below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of one embodiment of the present invention.As shown in Figure 1, through the produced part of this process as an example, be that two symmetrical parts are made together in this example, this method is suitable equally to single part, note the solution of its side force.This method will draw that moulding combines with flange, in punching course, part done according to having Z-shaped flange moulding of binder up and down.
Draw regional Y is pushed down after drawing work finishes always; Guarantee in turn-up process, can not influence the quality of product because of flowing of material; In flange zone X at first, that exterior material inwardly flows is too fast, the very high meeting of flange height in the flange zone X with draw regional Y junction and serious folded material, wrinkling occur.As shown in Figure 2, the upper side in the flange zone is provided with step surface and bead, holding pad 2 is set in upper bolster 1 pushes down material, slows down its flowing velocity in turn-up process, has solved folded material, wrinkling.
This mould comprises upper bolster 1, die 3, goes up holding pad 2, die shoe 6, flanging die 4, blank holder 7, draws punch 5 and punch retainer 8.
Like Fig. 2, shown in Figure 3, in drawing process, draw punch 5 and be movable pattern with punch retainer 8, pressure source is the push rod 9 of lathe, draws punch 5, blank holder 7 and punch retainer 8 at first at flange and under the thrust of push rod 9, begins flange.This pressure source also can be nitrogen spring, notices that its initial pressure is greater than pressure-pad-force and drawing pressure.
Die 3 is as the die of drawing work content and the flange die of flanging process content, and in turn-up process, the flanging die 4 that is arranged on the die shoe 6 turns over material on die 3.
Blank holder 7 is as the parts of in drawing work, pushing down material, and its pressure source is the nitrogen spring 10 that is installed in the punch retainer 8, for the ease of adjusting the speed that flows of its material, bead is set on press surface.
