It is important to note that, as shown in fig. 10 and 11, when the mounting seat 641 moves forward, the connecting rod b643 interferes with the end of the connecting rod c644, and at this time, the prong 6222 forms a triangle with the mounting seat 621, the mounting seat 621 can bend the angle steel 10 with the prong 6222, and the friction wheel 6231 rolls over the friction strip 6232 due to the action of the ratchet assembly.
The working process of the equipment is as follows:
the upper die 4 moves downwards and drives the material shifting component 51 to rotate through the control component 52, one angle steel 10 slides onto the lower die 2, the stamping device 3 drives the upper die 4 to move downwards, the punch 41 is matched with the chute 21 to cut the angle steel 10, then the upper die 4 moves upwards, the cylinder 641 pushes the mounting seat 621 and the thimble component 622 to move forwards, the vertex angle of the rotating plate 631 is clamped into the chute 21, the tip 6222 is butted with the angle steel 10 and is matched with the chute 612 to bend the angle steel 10, one side edge of the angle steel 10 is clamped into the accommodating groove 60, the other side of the angle steel 10 is tightly attached to the mounting seat 621, meanwhile, the wedge block b633 fixes the angle steel 10, and then the cylinder 641 drives the mounting seat 621 and the angle steel 10 to move backwards, 6231 with rub strip 6232 cooperation, mount pad 621 moving speed reduces, tip 6222 with the mount pad 621 dislocation, angle steel 10's seam leaks, simultaneously go up mould 4 and drive when moving down the cutting angle once more soldered connection subassembly 71 moves down and welds seam department, after the welding is accomplished, it drives to go up mould 4 the soldered connection subassembly 71 moves up, afterwards rub wheel 6231 with rub strip 6232 breaks away from the cooperation, mount pad 621 resets, next gear 6341 with rack 6342 meshes, the rotating plate 631 upset downwards, after upset to certain angle, angle steel 10 breaks away from wedge b633 is spacing, angle steel 10 falls into for being located in the inside workbin 11 of workstation 1.
