[0050] Before starting the stamping work, the equipment needs to be checked comprehensively to ensure that the parts are firmly connected and move flexibly. First, check whether the stamping groove 101, auxiliary positioning cylinder 103, limiting plate 102 and other parts on the lower die 1 are clean and free of foreign matter, and clean them in time if there is any. Second, check whether the stamping head 202 and the camber block 201 on the upper die 2 are installed correctly and the surface is smooth. Then check whether the telescopic rod 1071 and the push plate 1072 in the push assembly can normally extend and slide, whether the return spring 1063 is elastic, whether the telescopic rod 1091 and the baffle 1092 can work normally, and finally check whether the collecting frame 4 and the vibration motor 401 are in normal state.

[0051] Place the plate-shaped stamping part to be processed on the limiting plate 102 of the lower die 1, as shown in Figure 1 The raw material is a plate-shaped metal plate, and the limiting plate 102 serves to limit the position of the stamping part to ensure accurate position during subsequent stamping process, avoiding failure or unqualified product due to position deviation. The operator should carefully align the positioning marks of the stamping part and the limiting plate 102 when placing the stamping part to ensure that the edges of the stamping part and the limiting plate 102 are closely attached.

[0052] Control the upper die 2 to move downward by the stamping machine, and approach the lower die 1. During the downward movement of the upper die 2, the stamping head 202 fixedly connected to the upper die 2 gradually approaches the stamping part above the stamping groove 101. When the stamping head 202 contacts the stamping part, continue to apply pressure to cooperate with the shape of the stamping groove 101 to stamp the stamping part into a preliminary stamping part with a circular bottom and two sides vertically raised. In this process, the semicircular design of the stamping groove 101 and the circular stamping end of the stamping head 202 work together to ensure that the bottom of the stamping part forms a regular circle, and the height and angle of the vertically raised parts on both sides are consistent.

[0053] After the first stamping is completed, the upper die 2 is lifted and reset, at this time, the pushing assembly is started, the telescopic end of the telescopic rod one 1071 is extended, pushing the push plate 1072 to slide in the stamping groove 101, the push plate 1072 contacts the preliminary stamped stamping part, pushes it from one end to the other end of the stamping groove 101, and makes it sleeved on the auxiliary positioning cylinder 103, the top protrusion of the auxiliary positioning cylinder 103 plays a guiding role in this process, ensuring that the stamping part is accurately sleeved thereon, and preparing for the subsequent second stamping.

[0054] After the pushing assembly pushes the preliminary stamped stamping part to the auxiliary positioning cylinder 103 and resets, the new stamping part is placed on the limiting plate 102 of the lower die 1 again, at this time, attention should be paid to the same operation as the last time of placing the stamping part, ensuring that the new stamping part is accurately positioned and closely attached to the limiting plate 102.

[0055] The upper die 2 is moved downward again by the control of the stamping machine, approaches the lower die 1, and contacts the extrusion surface 1062 on the auxiliary forming block 1061 while the new stamping part is first stamped, with the continuous descent of the upper die 2, the arc block 201 on the upper die 2 exerts pressure on the extrusion surface 1062, so that the auxiliary forming block 1061 moves in the sliding groove 105 towards the auxiliary positioning cylinder 103, and the quarter circular shapes on the two groups of auxiliary forming blocks 1061 are spliced into a semicircle, cooperating with the auxiliary positioning cylinder 103 to extrude the vertically raised parts on both sides of the preliminary stamped stamping part sleeved on the auxiliary positioning cylinder 103 into a circular shape, and then make the stamping part into a hollow circular tube with an open seam at the top, in this process, the return spring 1063 is compressed to store elastic potential energy.

[0057] After the blanking is completed, the pushing assembly and the telescopic rod two 1091 are reset, the telescopic end of the telescopic rod one 1071 of the pushing assembly is shortened, and the pushing plate 1072 is driven to return to the initial position; the telescopic end of the telescopic rod two 1091 is extended, and the baffle 1092 is again attached to the side of the auxiliary positioning cylinder 103 away from the pushing plate 1072, ready for the next stamping, at the same time, the auxiliary forming block 1061 returns to the initial position under the action of the reset spring 1063, then the stamping production is cycled until all the stamping parts are processed.

[0058] The present application ensures the accurate position of the stamping part in each stamping process through the setting of the auxiliary positioning cylinder 103 and the limiting plate 102, improves the consistency of the product, and the cooperation of the stamping groove 101, the stamping head 202 and the auxiliary forming block 1061 enables the stamping part to be accurately formed into a circular tube with an open seam at the top, meeting the requirements of the subsequent welding of the wire nose.
