(2), will disperse the metalwork after punching to move in secondary punching shaving die module, punching is carried out in residue position, hole, simultaneously two groups of corresponding limits that there is no arc incision on die-cut lower band feeding direction and have the cutting shoulder of circular arc side, the so-called corresponding limit that there is no arc incision, namely two limits do not arrange arc incision relatively and all; Pilot pin by two plug screw formulas in this step is accurately located metalwork base material; In technique, adopt and rush all the other and be alternately distributed the method in hole and sweep away two groups of Symmetry Edges on band feeding direction simultaneously, its objective is and ensure that material deformation is even. On mould, be designed with in addition the pilot pin of the two plug screw formulas that can lock, as shown in Figure 4, ensure positioning precision. The board-like elastic tripper of elasticity discharging of this module.
(3), in one-level bending mould module, first do not have the symmetrical side of arc incision to carry out bending to two after die-cut; Doing is like this stress balance that ensures metalwork matrix structure. On mould, middle part is designed with gathering sill floating roof device, and as shown in Figure 5, this gathering sill floating roof device is the double action with guiding and floating roof bool as elastic device.
(4), enter the die-cut module of secondary, the limit on the die-cut opposite that has arc incision one side, namely remaining the last item limit, carries out substep by both sides opposite side respectively die-cut, its objective is and ensures that material deformation is even.
(5), enter secondary bending mould module, the side and the opposite side thereof that after die-cut, have arc incision are carried out to bending; The another side of bending metals part base material, limit portion adopts the pilot pin that has the two plug screw formulas that can lock, and lead and floating roof to metalwork base material by elastic guide groove floating roof device in middle part;
(6), enter cut-out die module, the coupling part of cutting-off part and band; Patrix is made up of punch retainer, punch and backing plate, and counterdie is made up of die and backing plate.
When the present invention uses, there is enough intensity in order to ensure die, the dispersion that the operation of progressive die will be tried one's best, institute is porose should be not die-cut on same station, first punching backlash profile. Hole is alternately disperseed die-cutly can avoid concentrating of stamping-out stress, improve service life and the also corresponding raising of production efficiency of mould. Adopt crooked position to carry out on two stations of being separated by, diastrophic degree relaxes, and surface of the work is difficult for scratch, and mold work condition is greatly improved, and has improved the service life of mould. Meanwhile, operation disperses the product Shape decomposition of original complexity to become several unit, die point simple shape, and mould manufacture is simple and be convenient to the replacing after wearing and tearing.
