[0045] In the embodiment of the utility model, when the device is ready to convey materials, the support plate 2 32 of the rotating support assembly 3 drives the rotating shaft 2 33 to rotate on the support plate 1 31. At this time, the sliding column 35 slides to the left along the slide groove 34 provided on the support plate 2 32. The sliding of the sliding column 35 drives the connecting plate 36 to rotate on the support plate 1 31. When the sliding column 35 slides to the left end of the slide groove 34, the baffle 30 and the rotating shaft 38 are pressed to rotate.

The lower end of the support plate 3 43 is fixedly connected, the spring 2 52 is sleeved on the limit fixing column 51 and is connected to the limit fixing column 51 in a one-to-one correspondence, the lower end of the upper mold 54 is fixedly connected to the clamping block 55, the rear end of the upper mold 54 is fixedly connected to the support column 221, the upper mold 54 and the clamping block 55 are both provided with slots 57, the lower end of the connecting column 56 passes through the upper mold 54 and is fixedly connected to the punching block 53, the lower end of the connecting column 56 is slidably connected to the upper mold 54, and the punching block 53 is slidably connected in the slot 57;

[0051] In the embodiment of the utility model, when the device starts to stamp the material, the limiting fixing column 51 of the upper mold assembly 5 is moved downward by the downward movement of the support plate three 43, and the upper mold 54 and the clamping block 55 are moved downward by the downward movement of the limiting fixing column 51. When the clamping block 55 slides into the limiting groove 214 to clamp the material, the upper mold 54 no longer moves. At this time, the support plate three 43 continues to move downward and compresses the spring two 52 to contract. The connecting column 56 is moved downward by the downward movement of the support plate three 43, and the stamping block 53 is moved downward along the slot 57 to stamp the material. When the stamping is completed, the upper mold 54 and the clamping block 55 are moved upward by the upward movement of the support plate three 43. At this time, the spring two 52 is no longer compressed and automatically resets. The clamping block 55 slides into the limiting groove 214 to fix the material and then stamps it, so as to avoid the material displacement caused by the force generated during the stamping process.
