TECHNICAL FIELD

[0002] In the field of automobile parts manufacturing, stamping process is a very important link. With the continuous development of the automobile industry, the production efficiency and quality requirements of automobile parts are also getting higher and higher. Efficient and stable stamping die plays a key role in improving the production efficiency of automobile parts and reducing production cost. It can ensure the dimensional accuracy and shape accuracy of automobile parts, thereby improving the performance and safety of the whole vehicle. At the same time, a good stamping die can also reduce the scrap rate in the production process and improve the material utilization rate, which is of great significance to the sustainable development of the automobile industry. Moreover, the degree of advancement of the stamping die also reflects the technical level and competitiveness of automobile manufacturing enterprises to some extent.

[0003] At present, in the stamping production process of automobile parts, in order to complete the stamping processing of automobile parts of different specifications, it is usually necessary to replace the upper and lower dies. The common method is to stop the operation of the stamping equipment first, manually disassemble the old die, install the new die, and then debug. In the aspect of feeding and discharging, it is generally through manual operation or simple mechanical device to feed and discharge one by one. Some enterprises use semi-automatic feeding mechanism, which needs workers to assist in placing the raw materials at the specified position; the discharging of the stamped automobile parts from the die is mostly relied on manual operation.

The second motor 46 drives the rotation of the sleeve 42 and the rotating plate 11 through the worm gear 44 and the worm 45, so as to realize non-stop replacement of the upper dies 13, and meanwhile, the self-locking action of the worm gear 44 and the worm 45 limits the rotation of the rotating plate 11 during stamping work.

[0035] Referring to Figure 1 , the mounting seat 12 is slidably connected with the rotating plate 11 in the vertical direction, the upper end surface of the rotating plate 11 is fixedly provided with a hydraulic cylinder for driving the mounting seat 12 to ascend and descend, and the upper end surface of the mounting seat 12 is further fixedly provided with two guide rods which pass through the rotating plate 11 upward. One of the two groups of mounting seats 12 and upper dies 13 is located above the stamping station, and the other is located on the other side of the rotating plate 11.

[0036] Referring to Figure 1 and Figure 2 , the mounting seat 12 is provided with a mounting groove 121 on one end surface which is parallel to the radial and vertical end surface of the fixed column 4, the mounting groove 121 is provided along the circumferential direction of the fixed column 4, the mounting groove 121 is an arc-shaped groove coaxial with the fixed column 4, the upper part of the arc-shaped groove is wider than the lower part, and the radial cross section is T-shaped.
