Described one-level rush the blanking die 1, secondary punching shaving die module 2, one-level bending mould module 3, the die-cut module 4 of secondary, secondary bending mould module 5 of dispersion hole and cut off die module 6 below make the in accordance with regulations stepping mechanism sent to of step pitch of metalwork base material for transmitting the metalwork base material;
One-level rushes that position, a hole, every interval arranges piercing punch on the blanking die 1 of dispersion hole, be provided with on the secondary punching shaving die module 2 with one-level and rush the punch that the punch location interval on the blanking die 1 of dispersion hole arranges, the both sides of secondary bending mould module 5 are provided with the pilot pin 8 that limit section is provided with the two plug screw formulas that can lock the metalwork base material, lead and the elastic guide groove floating roof device 9 of floating roof to the metalwork base material in the middle part of secondary bending mould module 5.
Be provided with the pilot pin that the metalwork base material is carried out pinpoint pair of plug screw formula on the described secondary punching shaving die module.
This installs each mold module and all designs independently formwork structure.When product size changes, reach the suitable idle station that arranges as long as suitably change the mould structure of each module, the complicated metalwork of the porous of the seriation that just can be shaped has increased the adaptability of mould, thereby has improved production efficiency, has prolonged die life.
The concrete steps of process for stamping that seriation porous complexity of the present invention patches metalwork are as follows:
(1), gets the metalwork base material, base material is carried out the cleaning on surface, then the metalwork base material is positioned over one-level and rushes and disperse punching and locating hole under the blanking die of dispersion hole, disperse the concrete form of punching to be: with default Kong Weiwei benchmark, position, a hole, every interval disperses punching; Adopt this punching to be alternately distributed the method in hole on the technique, its main purpose is to make material stressed evenly, be out of shape more evenly, guarantees punching quality, and punch distributes and disperses concerning die module in addition, and the close mold center in Center of Pressure has prolonged die life.This module also is designed with the technique of rushing locating hole, and this fabrication hole matches with the pilot pin of subsequent module, guarantees the stepping accuracy of mould and the precision of automatic feed mechanism.This module also is designed with device for discharging, adopts 4 groups of springs as elastic tripper.
(2), will disperse the metalwork after the punching to move on the secondary punching shaving die module, punching is carried out in residue position, hole, two groups of corresponding limits that do not have arc incision on the die-cut lower band feeding direction and the cutting shoulder of circular arc side is arranged simultaneously, the so-called corresponding limit that does not have 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 the metalwork base material; Adopt on the technique and rush all the other and be alternately distributed the method in hole and sweep away simultaneously two groups of Symmetry Edges on the band feeding direction, its objective is to guarantee that material deformation is even.Be designed with in addition the pilot pin of the two plug screw formulas that can lock on the mould, as shown in Figure 4, guarantee positioning accuracy.The board-like elastic tripper of elasticity discharging of this module.
(3), on one-level bending mould module, do not have the symmetrical side of arc incision to carry out bending to two after die-cut first; Doing like this is the stress balance that guarantees the metalwork matrix structure.The position is designed with gathering sill floating roof device in the middle of on the mould, and as shown in Figure 5, this gathering sill floating roof device is as the double action of elastic device with guiding and floating roof bool.
(4), enter the die-cut module of secondary, the die-cut limit that the opposite of arc incision one side is arranged, remaining the last item limit namely, it is die-cut respectively that the both sides opposite side is carried out substep, its objective is that the assurance material deformation is even.
(5), enter secondary bending mould module, side and the opposite side thereof that arc incision is arranged after die-cut carried out bending; The another side of bending metals spare base material, limit section adopts the pilot pin that the two plug screw formulas that can lock are arranged, and lead and floating roof to the metalwork base material by elastic guide groove floating roof device in the middle part;
(6), enter cut-out die module, the coupling part of cutting-off part and band; Patrix is comprised of punch retainer, punch and backing plate, and counterdie is comprised of die and backing plate.
When the present invention uses, in order to ensure die enough intensity is arranged, 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.The hole is alternately disperseed die-cutly can avoid concentrating of stamping-out stress, improve mold use life-span and also corresponding raising of production efficiency.Adopt crooked position to carry out at two stations of being separated by, diastrophic degree relaxes, and surface of the work is difficult for scratch, and the mold work condition is greatly improved, and has improved the mold use life-span.Simultaneously, operation disperses original complicated product Shape decomposition is become several unit, the die point simple shape, the mould manufacturing simple and be convenient to wear and tear after replacing.
