The operation principle of Wedge mechanism 8 is as follows:
When patrix is descending, the trace drive block 814 of the driving wedge 81 on upper bolster 16 promotes drive division 831 first downwards, first trace 83 is under the action principle of lever, and the second trace 84 is lifted by the second connecting axle 841 by its other end, and flanging insert 86 is also lifted.
Drive wedge 81 to continue descending, its limited block 812 withstands the state that the first trace 83 keeps lifting.
When drive the driving inclined-plane 813 of wedge 81 act on by dynamic wedge 82 by dynamic inclined-plane 821 time, move to the second trace 84 direction by dynamic wedge 82, also make flanging insert 86 move to the 2a1 direction, flanging arc limit on flanging post 2a, and stamping parts B flanging pass through the flanging arc limit 861 of flanging insert 86 and the flanging arc limit 2a1 attaching and compacting on flanging post 2a the most at last.
After side shaping completes, up the making of patrix drives wedge 81 to be separated with by dynamic wedge 82, and the first trace 83 resets under the effect of the second back-moving spring 833, resets under the effect of the first back-moving spring 8271 by dynamic wedge 82.
As shown in Figure 3, stamping parts B flanging by the flanging arc limit 861 of flanging insert 86 and the flanging arc limit 2a1 attaching and compacting on flanging post 2a, and forms flanging B1.
As shown in Figure 4, the structure of the second flange die is identical with the structure of the first flange die, and the flanging arc limit 2a1 just on flanging post 2a replaces with flange arc limit 2a2.Corresponding Wedge mechanism 8 is replaced by flange insert 87.Flange flanging 871 and the flange arc limit 2a2 attaching and compacting on flanging post 2a of flange insert 87, and form flange A1.
In addition, patrix drift 11 is fixed with the punching module 111 matched with the die cavity of the blank on stamping parts B.Lower bolster 22 is fixed together by screw and die shoe 2.Right inserting column 25 and left inserting column 27 all have two.Flanging post 2a has two.Nitrogen spring 29 has two.
As illustrated in Figures 5 and 6, stamping parts compresses position-limit mechanism 3 and comprises cylinder 33, stamping parts clamping lever 35, backstay 39 and lever dolly 37, cylinder 33 one end is fixed on die shoe 21 sidewall by cylinder stiff end 32, cylinder 33 other end is connected with one end of stamping parts clamping lever 35 by cylinder connecting screw rod 34, stamping parts clamping lever 35 is connected with lever dolly 37 by pivot bolt 36, lever dolly 37 is fixed on die shoe 31 end face, the other end of stamping parts clamping lever 35 is stamping parts compressed part and has U-shaped current groove 351, backstay 39 one end is fixed on die shoe 31 end face, backstay 39 other end inserts in described U-shaped current groove 351, backstay 39 is through the locating hole on stamping parts B.The stamping parts B compressed part outside of stamping parts clamping lever 35 other end is coated with resilient protection part 38.
In order to adapt to the height of stamping parts B, on backstay 39, cover has a pad bit slice 31.
The operation principle that stamping parts compresses position-limit mechanism is: be enclosed within backstay 39 by stamping parts B by locating hole on it; Then, start cylinder 33, cylinder 33 promotes cylinder rod and moves upward, cylinder promotes stamping parts clamping lever 35 one end and moves up, stamping parts clamping lever 35 other end moves down, and stamping parts clamping lever 35 is undertaken spacing by U-shaped current groove 351 and makes the stamping parts compressed part of stamping parts clamping lever 35 finally withstand stamping parts B.
The method of work of diel of the present invention is as follows:
Step 1, stamping parts B have straight flange B1 after punching press above, and stamping parts B to be placed between patrix 1 and counterdie 2 and to compress position-limit mechanism by stamping parts and carries out compression and spacing;
Step 2, patrix drift 11 are to pressing down stamping parts B, and straight flange B1 walks downwards along flanging arc limit 2a1; Patrix drift 11 has also been pressed in the stamping parts B on upper padding plate 24 simultaneously, Wedge mechanism 8 on upper and lower die holder moves downward the thrust of generation by patrix, stretch to flanging arc limit 2a1 on flanging post 2a by being positioned at mold exterior flanging insert 86, and the straight flange B1 of stamping parts B is compacted into flanging B2;
Step 3, patrix to be risen, the flanging post 2a with flanging arc limit 2a1 is replaced by the flanging post 2a with flange arc limit 2a2, or directly uses second flange die with the flanging post 2a of flange arc limit 2a2; The flanging insert 86 on the second trace 84 top is replaced with flange insert 87 simultaneously.
Step 4: the stamping parts B with flanging B2 to be placed between patrix 1 and counterdie 2 and to compress position-limit mechanism by stamping parts and carries out compression and spacing;
Step 5, patrix drift 11 are to pressing down stamping parts B, and flanging B2 walks downwards along flange arc limit 2a2; Patrix drift 11 has also been pressed in the stamping parts B on upper padding plate 24 simultaneously, Wedge mechanism 8 on upper and lower die holder moves downward the thrust of generation by patrix, stretch to flange arc limit 2a2 on flanging post 2a by being positioned at mold exterior flange insert 87, and the flanging B2 of stamping parts B is compacted into flange A1;
Flanging B2 after the first flange die punching press, then through the second flange die punching press, is pressed into the flange A1 shown in Fig. 4, this completes flange punching press by stamping parts B.
After punching press completes, patrix 1 rises, and nitrogen spring 29 and spring 28 are by lower plate 23 and upper padding plate 24 jack-up, and now flanging B2 can deviate from smoothly from counterdie 2, and Wedge mechanism 8 is returned to reset condition under the effect of back-moving spring.
If adopted, the second flange die is disposable to be gone out flange A1, then there is the problems of mechanical strength of flange, and the present invention adopts and first straight flange B1 struck out flanging B2, and then strikes out the mode of flange A1, can ensure the mechanical strength of flange A1 like this.
The demoulding principle of the second flange die is the same with the demoulding principle of the first flange die, and the patrix 1 that the second flange die is used is simultaneously also identical with patrix 1 structure used in the first flange die.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious realization of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all in protection scope of the present invention without to improve.
