[0002] A stamping die is a special process equipment used to process materials into parts or semi-finished products during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the required parts. In the process of automobile production, a large number of parts are produced using stamping dies.

[0003] When stamping disc-shaped sheets, since the disc-shaped sheets are difficult to position, workers usually place the materials on the corresponding molds. This method imposes a high labor intensity on the workers. In order to reduce the labor intensity of the workers, the prior art uses an automatic loading mechanism to replace manual loading. However, the existing automatic loading mechanism can only be applied to sheets of one diameter, and the versatility of the device is low. When processing sheets of different diameters, the corresponding positioning tooling needs to be replaced. The replacement process of the positioning tooling takes up a lot of production time, affecting production efficiency. Utility Model Content

[0027] When the sheet metal is pushed to the lower die 17, the sliding plate 3 is moved to the lower die 17 by the hydraulic rod 4, and the sheet metal at the bottom of the sheet metal stack is pushed to the lower die 17 for stamping.

[0028] In this embodiment, the gear transmission assembly includes a connecting rod 10, which is fixedly mounted on the rotating shaft of the positioning seat 8. A first bevel gear 11 is fixedly mounted on the lower end of the connecting rod 10. A transmission rod 12 is provided between the first bevel gears 11. The transmission rod 12 is rotatably mounted on the workbench 2 through a bearing seat. Second bevel gears 13 are fixedly mounted on both ends of the transmission rod 12, and the first bevel gear 11 is meshed with the second bevel gear 13.

[0029] In this embodiment, a handwheel 14 is rotatably mounted on the side wall on the front side of the workbench 2, a worm 15 is fixedly mounted on the rotating shaft of the handwheel 14, the other end of the worm 15 is rotatably mounted on the workbench 2, a worm wheel 16 is matched with the worm 15, and the worm wheel 16 is fixedly mounted on the transmission rod 12. The handwheel 14 drives the transmission rod 12 to rotate through the worm wheel 16 and the worm 15, and the transmission rod 12 drives all the positioning seats 8 to rotate synchronously in opposite directions when rotating.

[0030] In this embodiment, four groups of positioning seats 8 are distributed in a square shape on the workbench 2, and the side walls of the four groups of positioning seats 8 are facing the diagonal direction. At this time, the plate with the smallest diameter can be positioned by the limiting columns 9, and the distance between the limiting columns 9 is adjusted by turning the hand wheel 14, so that the plate with a larger diameter can be positioned. The bottom ends of the two groups of limiting columns 9 away from the stamping assembly are tightly fitted with the top surface of the workbench 2, and a gap is provided between the bottom ends of the two groups of limiting columns 9 close to the stamping assembly and the top surface of the slide seat, and the gap is only for a single plate to pass through.

[0031] In this embodiment, a push plate 6 is welded to one side of the push block 5 close to the positioning assembly, and a V-shaped groove 61 is provided at one end of the push plate 6 away from the push block 5. The push block 5 contacts the sheet material through the push plate 6. The thickness of the push plate 6 is less than the thickness of the sheet material, so as to avoid interference between the push block 5 and the stamping lower die 17 when the sheet material is pushed onto the stamping lower die 17. In the process of pushing the sheet material, the V-shaped groove 61 is used to support the sheet material to prevent the position of the sheet material from shifting forward and backward.

[0033] The specific working process of the utility model is as follows. When performing stamping processing, the sheet materials are stacked and placed between the limit columns 9, and then the transmission rod 12 is driven to rotate by the hand wheel 14. When the transmission rod 12 rotates, it will drive all the positioning seats 8 to rotate synchronously in the opposite direction, so that the side walls of the limit columns 9 abut against the side walls of the sheet materials. The sheet materials are positioned by the limit columns 9, so that sheets of different sizes can be positioned. At the same time, by adjusting the position of the pusher block 5, the front end of the pusher block 5 abuts against the side walls of the sheet materials, and the positioning bolts 7 are tightened so that the bottom of the positioning bolts 7 abuts against the slide 3, so as to position the pusher block 5. Therefore, there is no need to adjust the stroke of the hydraulic rod 4, and the sheet materials of different diameters can be pushed to the same position. When pushing the sheet materials, the slide 3 is driven to move toward the stamping lower die 17 by the hydraulic rod 4, and the sheet materials at the bottom are pushed to the stamping lower die 17 by the pusher block 5 for stamping processing, thereby realizing automatic loading of the sheet materials, reducing the labor intensity of the staff, and effectively improving the production efficiency.
