Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically relating to an integrated stamping die for simultaneous production of multiple products at multiple workstations. Background Technology

[0002] Stamping is a processing method that uses a press and a die to apply external force to a metal sheet, causing it to undergo plastic deformation or separation to obtain the desired shape. It has the advantages of high efficiency, high precision, and high material utilization. Stamping dies are an essential component in the stamping process. Stamping dies generally include an upper die and a lower die. When the upper die and the lower die are closed together, the middle part is stamped to form the shape of the upper die and the lower die.

[0003] However, current stamping dies can often only process parts of one specification. When it is necessary to change the size of the stamping hole of the part, it is necessary to disassemble and reassemble the modified part or to add another set of dies for processing. The operation is time-consuming and labor-intensive. Moreover, too many dies and longer production lines will increase the difficulty of automated production. For some orders with large quantities and short delivery times, traditional production processes are difficult to complete on time.

[0004] Currently, the industry often needs to produce a type of stamping, such as... Figure 3 The disc-shaped stretched part with a punched hole in the middle is shown. The size of the punched hole varies depending on the needs. In other words, the size of the punching die is different. In traditional processing, it is necessary to change the alternative parts or process it through another stamping line. If only a small number of parts of different specifications need to be produced, or if it is necessary to frequently switch to produce parts of multiple specifications, it will not only increase the cost of the die, but changing the alternative parts will also reduce the production efficiency, which will seriously affect the automated production process.

[0005] In view of the above-mentioned problems, it is necessary to design an integrated multi-station, multi-product synchronous production stamping die capable of quickly switching between processing parts of different specifications. To this end, the applicant has ingeniously designed this technical solution. Utility Model Content

[0032] Please see Figures 1-3 During the stamping process, the robotic arm first places the sheet metal from the feed port 281 between the outer stamping punch 22 and the outer stamping die 12. When the die is closed, the outer stamping die 125 and the outer stamping lower die 221 cooperate to stamp the sheet metal out. Figure 3 The sheet 10 shown in Figure a; after the outer shape is stamped, the sheet 10 is placed on the lower drawing die 231 of the drawing and stamping punch 23 by a robot arm and held by the drawing and stamping jaws 232. When the die is closed, the lower drawing die 231 and the drawing die 134 cooperate to stamp out the outer shape of the sheet 10. Figure 3 The stretching step 101 and punching concave surface 102 are shown in Figure b. Next, the sheet 10 that has completed stretching and stamping is placed into the lower punching die 241 of the punching die 24 by a robot arm and held by the punching claw 242. When the die is closed, the lower punching die hole 2411 and the punching die 1431 cooperate to punch out the hole at the punching concave surface 102. Figure 3 The small hole 103 is shown in Figure c. Next, the robotic arm places the sheet 10 with the small hole 103 formed into the large hole forming die 25, and clamps it with the large hole forming claw 252. When the required product has a larger hole diameter, the insert block 1524 is inserted into the large hole forming die relief groove 1523. During die closing, the large hole lower die hole 2511 engages with the large hole forming die 1531, further enlarging the small hole 103 into a larger diameter hole. Finally, the robotic arm removes the finished product. When the required product's small hole diameter 103 does not need to be changed, the insert block 1524 is removed from the large hole forming die relief groove 1523. During die closing, the large hole forming die 1531 moves upward and cannot punch the small hole 103 again, thus achieving simultaneous production of multiple stations and multiple products, greatly improving production efficiency.
