Description

Technical Field

[0001] The utility model belongs to the technical field of metal product processing, and particularly relates to a stamping and unwinding device used for metal product processing. Background Art

[0002] Metal coil stamping unwinding is the process of unwinding a coil of metal material during the stamping process. The metal coil is typically placed on an unwinder, which is driven by a motor or other power device to gradually unwind the coil. During the unwinding process, the unwinding speed must be controlled to ensure it matches the processing speed of the stamping equipment.

[0003] However, the existing unwinding device generally lacks a cleaning structure for the coil. During the processing or transportation of the metal coil, a lot of dust and impurities will adhere to its surface. In addition, during the processing of the coil, oil stains and oxides will also adhere to it. Therefore, if the metal coil is not cleaned before stamping, the oxides, oil stains and particles on the surface of the metal coil will easily affect the surface smoothness and quality of the coil after forming.

[0004] Therefore, a punching unwinding device for metal product processing is designed to change the above technical defects. Utility Model Content

[0025] This specific embodiment is a stamping unwinding device for metal product processing, and its structural diagram is shown as follows: Figures 1-6 As shown, it includes a support plate 1, the side wall of the support plate 1 is rotatably connected to the support rod 2, two limit plates 4 are sleeved on the support rod 2, the two limit plates 4 are distributed in opposite directions, and the limit plates 4 are all cross-shaped structures. The side wall of the support rod 2 is threadedly connected with a nut 3, and the side wall of the limit plate 4 is slidably connected to an extension plate 6. The front side wall of the rear extension plate 6 is evenly fixedly connected to a positioning rod 7, and the side walls of the extension plate 6 are all threadedly connected with bolts 9, and the bolts 9 are all against the limit plates 4. The rear side wall of the support plate 1 is fixedly connected to a transmission box 10, and the support rod 2 is connected to the transmission box 10 in transmission mode. A motor 11 is installed on the top surface of the transmission box 10. The output end of the motor 11 is connected to the transmission box 10 in transmission mode. The cooperation between the motor 11 and the transmission box 10 belongs to the existing technology. Its specific principle and structure will not be described in detail in this solution. A groove 12 is formed on the side wall of the support plate 1. Two movable blocks 13 are slidably connected in the groove 12. Two round rollers 14 are rotatably connected to the side wall of the movable block 13. A cleaning felt 19 is connected to the side wall of the round roller 14. An adjustment component is provided in the groove 12.

[0026] like Figure 4 and Figure 6 As shown, the adjustment assembly includes a screw rod 15 rotatably connected to the side wall of the groove 12, the threads on the side wall of the screw rod 15 are symmetrically arranged in opposite directions, a screw hole is provided on the side wall of the movable block 13, the screw rod 15 is threadedly connected to the screw hole, the side wall of the screw rod 15 is fixedly connected to the first bevel gear 16, a second bevel gear 17 is engaged with one side of the first bevel gear 16, and a rotating rod 18 is fixedly connected to the side wall of the second bevel gear 17, which passes through the support plate 1 and is movably connected to it.

[0027] Specifically, the adjustment component can be used to adjust the distance between the two side rollers 14 to adapt to metal coils of different thicknesses. During the unwinding process of the metal coil, the friction between the coil and the cleaning felt 19 can drive the rollers 14 to rotate, thereby achieving the effect of efficiently cleaning the coil.

[0028] like Figure 5 As shown, the side walls of the limiting plate 4 are each provided with a sliding groove 5 , and the extension plate 6 is slidably connected to the sliding groove 5 .

[0029] Among them, the cross-sectional shape of the slide groove 5 can be T-shaped, trapezoidal, L-shaped or other shapes, which is used to limit the extension plate 6 to prevent the extension plate 6 from falling out of the slide groove 5, thereby improving the stability of the extension plate 6.

[0030] like Figure 1 and Figure 5 As shown, the front side wall of the rear extension plate 6 is fixedly connected with a plurality of pull rods 8. The pull rods 8 are convenient for the user to hold and control the limit plate 4, and when the coil is supported, it is convenient to manually unwind the coil and introduce the coil into the punching machine.

[0031] like Figure 6 As shown, one end face of the movable block 13 is open, the end face of the round roller 14 is fixedly connected with an insertion rod 20, the side wall of the insertion rod 20 is provided with an annular groove, the side wall of the movable block 13 is threadedly connected with a screw 21, and the screw 21 extends into the annular groove.

[0032] When the round roller 14 rotates, the insertion rod 20 always rotates at the same position through the cooperation between the annular groove and the screw 21, which ensures its rotation while preventing the round roller 14 from being separated.

[0033] like Figure 6 As shown, the side wall of the round roller 14 is fixedly connected with a magic tape 22, and the cleaning felt 19 is bonded to the magic tape 22. The connection method of the magic tape 22 is adopted, which makes it easy to remove the old cleaning felt 19 and replace it with a new one. When replacing, it can be directly glued around the round roller 14, which is simple and convenient to operate.

[0034] Working principle: First, support the metal coil, loosen the nut 3 to remove the outer limit plate 4, then loosen the bolt 9 to release the fixation of the extension plate 6, and then adjust the spacing between the positioning rods 7 according to the inner diameter of the metal coil, tighten the bolt 9 to fix it, and then place the metal coil on the positioning rod 7, and then put the outer limit plate 4 on the support rod 2 and tighten the nut 3 to support and limit the metal coil, and then pass one end of the metal coil through the two round rollers 14, and then rotate the rotating rod 18 to drive the second bevel gear 17 to rotate, the second bevel gear 17 engages the first bevel gear 16 and drives the screw 15 to rotate, the screw 15 drives the movable blocks 13 on both sides to move relative to each other, thereby driving the cleaning felt 19 to fit closely with the metal coil. During the discharge process, the metal coil can use the cleaning felt 19 to clean the dust and oil adhering to its surface, which is beneficial to improving the stamping quality of the coil.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
