[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a side limit stamping die.

[0027] The utility model provides Figure 1-3 A side limit stamping die shown includes an upper die 1 and a lower die 2, a support frame 3 is fixedly provided at the bottom of the lower die 2, a material collecting mesh box 22 is placed at the lower end of the support frame 3, a through hole is opened inside the lower die 2, rotating rods 4 are rotatably provided on both sides of the inner wall of the through hole, damping sleeves 13 are fixedly penetrated on both sides of the inner wall of the through hole, the rotating rod 4 is rotatably arranged in the damping sleeve 13, a forming support plate 5 is fixedly provided between the two rotating rods 4, two symmetrically arranged side baffles 6 are fixedly provided on the outer wall of the forming support plate 5, a pushing block 7 is fixedly provided at the bottom of the upper die 1, a side pushing block 8 is cooperated with the bottom of the pushing block 7, the pushing block 7 and the side pushing block 8 are both inclined on the side close to each other, and the side pushing block 8 is in contact with the top of the lower die 2.

[0028] Before stamping the workpiece, the workpiece is placed on the forming support plate 5 and is pushed by the side baffle plate 6. Then the upper die 1 approaches the lower die 2, and the pushing block 7 pushes the side push block 8, so that the side push block 8 moves laterally to support and limit the side of the workpiece to ensure the stability of the workpiece during the stamping process. After the workpiece is stamped, the upper die 1 gradually moves away from the lower die 2. At this time, the rotating rod 4 drives the forming support plate 5 to flip under the support of the damping sleeve 13, so that the stamped workpiece falls and the other side of the forming support plate 5 is flipped and set upward, and the workpiece can be supported to continue the stamping work, so that the workpiece can be unloaded after stamping without manual removal, thereby improving the stamping safety and stamping efficiency.

[0029] In order to enable the forming support plate 5 to be turned over after the surface workpiece is stamped and formed to complete the autonomous unloading of the workpiece, as Figure 1 As shown, a vertical plate 9 is fixedly provided at the bottom of the inner wall of the support frame 3, and a transmission mechanism is provided between the vertical plate 9 and the rotating rod 4. The transmission mechanism includes a transmission rod 10, and the transmission rod 10 is rotatably connected to the upper end of the vertical plate 9. The rod walls of the rotating rod 4 and the transmission rod 10 are both fixedly sleeved with synchronous wheels 11, and the outer sides of the two synchronous wheels 11 are commonly sleeved with a synchronous belt 12.

[0030] When the workpiece is stamped, the transmission rod 10 starts to rotate. Through the synchronous transmission between the synchronous belt 12 and the synchronous wheel 11, the rotating rod 4 can drive the forming support plate 5 to rotate to complete the unloading of the workpiece.

[0031] In order to enable the transmission rod 10 to be driven to drive the forming support plate 5 to flip after the upper mold 1 is away from the lower mold 2, as shown in FIG. Figure 1-2 As shown, a sliding hole is provided inside the lower mold 2, and a one-way driving mechanism is provided between the side push block 8 and the sliding hole. The one-way driving mechanism includes a slide plate 14, which is fixedly connected to the bottom of the side push block 8 and is slidably arranged in the sliding hole. A first spring 15 is fixedly provided between the slide plate 14 and the inner wall of the sliding hole, a cross plate 16 is fixedly provided at the bottom of the slide plate 14, and a plurality of grooves arranged at intervals are provided on the top of the cross plate 16, a cross bar 17 is fixedly provided in the groove, a driving plate 18 is fixedly provided on the rod wall of the cross bar 17, a second spring 19 is fixedly provided between the driving plate 18 and the inner wall of the groove, and the driving plate 18 is cooperated with a plurality of connecting plates 20 arranged in a symmetrical manner, a rotating plate 21 is fixedly provided between the plurality of connecting plates 20, and the rotating plate 21 is fixedly sleeved with the transmission rod 10.

[0032] When the upper mold 1 is close to the lower mold 2, the side push block 8 is pushed and drives the slide plate 14 to move laterally. At this time, the first spring 15 is stretched, and the cross plate 16 moves according to the slide plate 14. At this time, multiple driving plates 18 can rotate along the cross bar 17 when contacting the driving plate 20 and squeeze the second spring 18, so that when the upper and lower molds are in contact, the forming support plate 5 is not pushed, and when the upper mold 1 is separated from the lower mold 2, the pushing block 7 gradually moves away from the side push block 8. At this time, the elastic force of the first spring 15 restores the lower slide plate 14 to move back. At this time, the cross plate 16 moves laterally, and the multiple driving plates 18 push the multiple connecting plates 20 under the restriction of the groove, so that the multiple connecting plates 20 drive the rotating plate 21 to rotate, so that the transmission rod 10 rotates, thereby driving the rotating rod 4 and driving the forming support plate 5 to rotate.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
