DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] Please refer to Figures 1-3 The wire drawing mechanism for non-ferrous metal processing in the embodiment comprises a support base 1, a wire drawing plate group 2 is fixedly installed on the top of the support base 1, two positioning mechanisms are fixedly installed on the top of the support base 1, the wire drawing plate group 2 is located between the two positioning mechanisms, a polishing mechanism is fixedly installed on the top right side of the support base 1, and a driving mechanism is arranged on the top rear side of the support base 1.

[0020] The wire drawing plate group 2 comprises a plurality of wire drawing plates with different hole diameters and is arranged from left to right in descending order.

[0021] In the embodiment, the positioning mechanism comprises a supporting plate 4, the supporting plate 4 is fixedly installed on the top of the support base 1, a U-shaped support 3 is fixedly installed on the top of the supporting plate 4, two adjusting blocks 5 are slidingly installed in the U-shaped support 3, a double-headed screw rod 11 is rotatably installed on the top of the U-shaped support 3, the adjusting blocks 5 are threadedly installed on the upper and lower ends of the double-headed screw rod 11 respectively, rotating shafts 7 are rotatably installed on the front sides of the adjusting blocks 5, positioning wheels 8 are fixedly installed on the outer sides of the rotating shafts 7 and located on the front sides of the adjusting blocks 5, transmission gears 9 are fixedly installed on the outer sides of the rotating shafts 7 and located on the rear sides of the adjusting blocks 5, and the upper and lower transmission gears 9 are meshed with each other.

[0022] It should be noted that the upper transmission gears 9 are installed on the outer sides of the upper rotating shafts 7 according to the thickness of the metal wire, so that the metal wire with different thicknesses can be stably drawn.

[0023] Specifically, by loosening the drive mechanism and rotating the double-headed screw 11, the upper and lower adjusting blocks 5 slide and move in opposite directions outside the U-shaped bracket 3, thereby causing the upper and lower positioning wheels 8 to move and separate in opposite directions. The metal wire to be drawn is placed on the lower positioning wheel 8 and passes through the wire drawing plate group 2 to achieve center positioning and wire drawing, thereby improving the efficiency of wire drawing.

[0024] In this embodiment, the drive mechanism includes a support plate 12 and a reduction motor 13. The support plate 12 is fixedly installed at the top rear end of the support base 1. Tensioning wheels 15 are fixedly installed at both the left and right ends of the front of the support plate 12. The reduction motor 13 is fixedly installed inside the support base 1. The output end of the reduction motor 13 and the outside of the lower rotating shaft 7 are both fixedly installed with transmission wheels 10. The transmission wheel 10 is externally driven by a transmission belt 16. The outside of the transmission belt 16 is in contact with the tensioning wheel 15. The upper transmission wheel 10 is located behind the adjusting block 5, and the wire drawing plate group 2 is located in front of the tensioning wheel 15.

[0025] It should be noted that the bearing plate 12 has two elongated holes. The tension wheel 15 is fixedly installed inside the elongated holes by a hand-tightening bolt. Therefore, when the positioning mechanism is adjusted, the hand-tightening bolt can be loosened to allow the tension wheel 15 to move inside the elongated holes. The tension wheel 15 is rotatably installed outside its axle.

[0026] Specifically, after the positioning mechanism has positioned the metal wire, the position of the tensioning wheel 15 outside the bearing plate 12 is adjusted to tension the transmission belt 16. This starts the reduction motor 13 to drive the lower transmission wheel 10 to rotate, which in turn drives the two upper transmission wheels 10 to rotate stably via the transmission belt 16. This causes the rotating shaft 7 to drive the lower transmission gear 9 to rotate in the opposite direction, causing the upper and lower positioning wheels 8 to rotate in the opposite direction and move the metal wire to the right for stable wire pulling.

[0027] In this embodiment, the polishing mechanism includes a fixed bracket 17 and a servo motor 14. The fixed bracket 17 is fixedly installed on the top right side of the support base 1. An adjustment bracket 18 is hinged to the top left end of the fixed bracket 17. A horn bolt 19 with one end extending into the fixed bracket 17 is inserted into the top of the adjustment bracket 18. Polishing wheels 6 are rotatably installed on the front of both the adjustment bracket 18 and the front of the fixed bracket 17. The axles of the upper and lower polishing wheels 6 pass through and extend to the rear sides of the adjustment bracket 18 and the fixed bracket 17, respectively. The servo motor 14 is fixedly installed on the back of the fixed bracket 17. The output end of the servo motor 14 is fixedly connected to the axle of the lower polishing wheel 6. The fixed bracket 17 is located on the right side of the right positioning mechanism. A through hole is opened at the top rear end of the support base 1. The transmission belt 16 is located inside the through hole. The horn bolt 19 is threadedly installed inside the fixed bracket 17.

[0028] It should be noted that by having the adjusting frame 18 drive the upper polishing wheel 6 to rotate upward or downward at the hinge point with the fixed bracket 17, the fine distance between the upper and lower polishing wheels 6 can be adjusted. Then, the spur bolt 19 is rotated to fix the adjusting frame 18 and the fixed bracket 17. The right side of the adjusting frame 18 is provided with a positioning groove, which allows the spur bolt 19 to move inside and press down to fix the adjusting frame 18 and the fixed bracket 17.

[0029] Specifically, after the metal wire is drawn, it enters between the upper and lower polishing wheels 6. The servo motor 14 is started to drive the lower polishing wheel 6 to rotate, so that the metal wire is continued to be driven to move to the right. At the same time, its surface is polished and flattened.
