[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profile, causing plastic deformation or separation, thereby obtaining stamped parts of the required shape and size. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force and deform it in the die, thereby obtaining product parts with certain shape, size, and performance.

[0003] Uncoiling the sheet metal is the first critical process in a coil-type stamping production line. Its core is to smoothly release and initially flatten the coiled sheet metal, providing a qualified raw material base for subsequent leveling, feeding, and stamping. The uncoiling and feeding processes in the stamping production line are crucial. After uncoiling, the sheet metal is transported to the stamping die via roller conveyors or conveyor belts, or the sheet metal may slide during transfer between multiple processes, resulting in inaccurate positioning of the sheet metal during the transfer process, and the sheet metal is prone to positional deviation during the transfer process. Utility Model Content

A rectangular rod 11 is engaged with the inner wall of the T-slot 3. The inner wall of the rod 11 is provided with a cross groove 16, and the outer surface of the rectangular rod 11 is provided with a threaded hole 19. The inner wall of the cross groove 16 is engaged with a connector 12. The outer surface of the rectangular rod 11 is fixedly connected with a second wheel rod 10. The outer surface of the second wheel rod 10 is rotatably connected with a driven wheel 9. The outer surface of the connector 12 is fixedly connected with a positioning rod 14. The outer surface of the positioning rod 14 is rotatably connected with a positioning wheel 15. The outer surface of the connector 12 is threaded with a fastening bolt 13. The outer surface of the rectangular bracket 2 is provided with an adjustment hole 18. The outer surface of the adjustment hole 18 is threaded with a positioning bolt 5.

[0022] In this embodiment, a rectangular bracket 2 is designed to facilitate the support of various parts. A T-slot 3 is provided on the inner wall of the rectangular bracket 2 to facilitate the engagement of the T-shaped piece 8 with the rectangular bracket 2. A sliding rod 4 is fixedly installed on the inner wall of the rectangular bracket 2 to facilitate smoother sliding of the T-shaped piece 8 and the rectangular rod 11 through the T-slot 3. The presence of the sliding rod 4 reduces the frictional resistance between the T-shaped piece 8 and the rectangular rod 11 and the inner wall of the T-slot 3, making their sliding process smoother and reducing wear caused by excessive friction, thus extending the service life of the parts. The rectangular rod 11 and the second wheel rod 10 are designed to facilitate the rotational connection of the second wheel rod 10 to the driven wheel 9. A cross groove 16 is provided on the inner wall of the rectangular rod 11 to facilitate the sliding connection of the connecting piece 12. A positioning rod 14 is designed to facilitate the rotational connection of the positioning wheel 15. To meet the multi-size sliding adjustment requirements of the connecting piece 12 on the inner wall of the rectangular rod 11, a threaded hole 19 is provided on the outer surface of the rectangular rod 11. Multiple optional positions are provided for fixing the positioning member and the rectangular rod 11. When the connecting member 12 slides to the appropriate position, it can be firmly fixed by the positioning bolt 5 passing through the threaded hole 19, thereby achieving stable fixing of the connecting member 12 in different size positions. The fastening bolt 13 is designed to be threadedly connected to the rectangular rod 11, which facilitates fixing the connecting member 12. The adjustment hole 18 is provided on the outer surface of the bracket 2, which facilitates the multi-size adjustment of the T-shaped member 8 and the rectangular rod 11 on the outer surface of the bracket 2.

[0023] Example 2 As shown in Figure 1- Figure 6 As shown, a first wheel rod 7 is fixedly connected to the outer surface of the T-shaped part 8. An auxiliary wheel 6 is rotatably connected to the outer surface of the rectangular bracket 7, and a fixing member 17 is fixedly connected to the outer surface of the rectangular bracket 2. In this embodiment, the T-shaped member 8 and the first wheel rod 7 are designed to facilitate the sliding connection of the first wheel rod 7. For bracket 2, the design of the first wheel rod 7 and the auxiliary wheel 6 facilitates the rotational connection of the auxiliary wheel 6 to the first wheel rod 7. The design of the fixing part 17 ensures that the T-shaped part 8 and the rectangular rod 11 will not derail when they slide on the inner wall of the bracket.

[0024] Working principle: As shown in Figure 1- Figure 6As shown, first, slide the rectangular rod 11 to the appropriate position of the adjustment hole 18, and fix the rectangular rod 11 in place by adjusting the positioning bolt 5. Then slide the T-shaped piece 8, and fix it after sliding it to the appropriate position. Because the size of the plate may vary depending on the work requirements, slide the positioning wheel 15 on the rectangular rod 11 to the appropriate position according to the size of the plate. Tighten the positioning bolt 5 to fix the positioning wheel 15 in the appropriate position. The plate can slide laterally by rotating the auxiliary wheel 6 and the driven wheel 9. The rotation of the positioning wheel 15 connects the two positioning wheels 15, so that the plate can be fixed between the two positioning wheels 15 while sliding laterally. Rolling friction replaces sliding friction, reducing the resistance in the positioning process, and playing a role in precise guidance and positioning, ensuring the accuracy of the plate's movement trajectory.
