Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to the present embodiment.
Detailed description of the invention
Based on the manufacturing process 90 ° of web surfaces carrying out backward flanging, first, the deformed area treating flange that will launch part by a pressure wave mould expands, and the edge, deformed area after expanding is pressed into waveform is used for storing, makes shown in prefabricated component (as Fig. 6).As depicted in figs. 1 and 2, first by deformed area
expand cFd to, wave edge length is cE+EF+FG+Gd, makes it be approximately equal to during design
next, then by a flanging molding die, prefabricated component backward flanging is become required form.
As shown in Figure 3 and Figure 4, pressure wave mould comprises cope match-plate pattern 1 and lower bolster 9, and be provided with punch retainer 2 below cope match-plate pattern, punch retainer bottom is provided with punch 3; Die holder 8 is installed above lower bolster, die holder is provided with the die 7 matched with punch shape, in the middle of die, be provided with the profile of coincideing with product web surface shape 10, the side, front and back of profile 10 is respectively equipped with the corrugated profile 11 of pressure, and two ends mills out the groove 12 of location.Cope match-plate pattern and lower bolster are provided with guide pillar guide pin bushing 5 by jack fastener 4, and guide pillar guide pin bushing guiding realizes die sinking with closed, and cope match-plate pattern is provided with also corresponding on lower bolster the limited post 6 being incorporated into the degree of depth for limiting patrix, and shut height leans on stop 6 to limit;
As shown in Figure 1 and Figure 5, before and after die, side is respectively equipped with the corrugated profile of pressure, and profile length is that cE+EF+FG+Gd is approximately equal to
the profile length of this kind of design can make 90 ° of bends
expand cFd to, flange is less likely to occur to break so again.
As shown in Figure 7, flanging molding die comprises cope match-plate pattern 13 and lower bolster 20, and cope match-plate pattern bottom is provided with flanging die 14; The top of lower bolster is provided with die socket 19, bottom is provided with press plates 22, and the top of die socket is provided with die block 18, is provided with location-plate 16 in the die block left and right sides, be equipped with by lathe push rod jack-up and the eccentric swage 17 flushed with die block in the middle of die block, press plates be provided with mould pin 21; Between cope match-plate pattern and lower bolster, pass through the guide pillar guide pin bushing 23 be contained on cope match-plate pattern and lower bolster respectively lead, and be contained in respectively on cope match-plate pattern and lower bolster for limiting cope match-plate pattern, to be incorporated into the limited post 24 of the degree of depth spacing, guide pillar guide pin bushing 23 leads, realize die sinking with closed, shut height limits by limited post 24.
The technical process of backward flanging manufacturing process of the present invention:
First, will treat that the expansion part of flange puts into the detent 12 of the die 7 of the lower bolster 9 of pressure wave mould, press slide drives cope match-plate pattern 1 descending, and the punch 3 be contained on cope match-plate pattern 1 is descending, and expansion part is bent into 90 degree, forms blank; Cope match-plate pattern continues descending, and blank both sides are pressed into wave-like by punch 3 and die 7, make prefabricated component, and then prefabricated component is taken out in die sinking.
Secondly, put into by above-mentioned prefabricated component on the die block 18 of Fig. 6 lower bolster 20, cope match-plate pattern 13 is descending, and prefabricated component is pushed down by convex module 14 and eccentric swage 17; Cope match-plate pattern 13 continues descending, and prefabricated component is pressed in the die block 18 in die socket 19, completes the flanging forming of prefabricated component.
Above-described embodiment, is only one of multifarious example, not limits the scope of the invention according to this.Therefore: the equivalence change done according to the structure of this example, shape and principle is all being covered by within protection scope of the present invention.This method also can apply to all analogous shapes (such as; Convex web flange) part shaping on.
