Step 3: carry out flange and reducing in the time of blanking.
Carrying out flange and reducing in the time of blanking is the key of present embodiment.Shown in Fig. 7,8,9, this step comprises following substep:
301: the blanking state;
302: beginning flange state;
303: beginning flange and reducing state;
304: the product shaping completion status.
As shown in Figure 1, the present embodiment progressive die forms workpiece one and has 12 stations, is exactly to be denoted as 12 stations of g1 to g12 among the figure, and this station figure as shown in Figure 6.
Explanation now uses mould as described above to finish the manufacture craft of the part (generally being referred to as supporting disk) in a kind of safe automobile air bag, it is by forming towards work steps such as fabrication hole, pull and stretch, shaping and blank-formings, its main work step stock layout figure as shown in Figure 1 comprises following work step:
Work step 1) towards fabrication hole g1: go out correcting nail hole, as shown in Figure 1, cloth goes out correcting nail hole and fabrication hole respectively on both sides, here correcting nail hole is accurately to locate usefulness for the work step of back, and fabrication hole is to prepare for the pull and stretch work step of back, promptly excise excess stock, keep pull and stretch body of material and carrier;
Work step 2) towards fabrication hole g2: with work step 1), fabrication hole is gone out as fine positioning in the correcting nail hole of going out with the preceding step, here towards the effect and work step 1 of fabrication hole) identical;
Work step 3) for empty work step g3: main purpose is that what mainly to finish because of first group of template is the deep-drawing technique that second group of plate of punching technology g2 will be finished, for make mould stressed rationally with dismantle easy to maintenance;
Work step 4) is empty work step g4: mainly be to consider that next step is the required space of pull and stretch work step g5 structure and the intensity of template;
Work step 5) be downward pull and stretch g5: the strip plate material is produced plastic deformation by mould, the shape that pull and stretch becomes to require, pull and stretch fillet at this moment is R1.0mm;
Work step 6) is empty work step g6: mainly be to consider that previous step is the required space of pull and stretch work step structure and the intensity of template;
Work step 7) shaping g7: will be at product at work step 5) the pull and stretch fillet R1.0 that forms is shaped to R0.3mm by mould, sees the operation part,
Work step 11) blank-forming g11: product is also carried out flange and reducing simultaneously from the strip separation, and this is crucial;
Work step 12) go out part and cut waste material g12: the work step product pushes away a work step forward in the utilization, the product of front release mould punching press scope is dropped on the preprepared conveyer belt send in the turnover box, cuts off unnecessary strip simultaneously;
