In the field of shaped copper wire drawing, the multi-stage guide wheel wear-resistant system is the core device to ensure the forming accuracy and surface quality of copper wires.
[0003] Existing shaped copper drawing equipment suffers from several problems: fixed guide wheels are prone to groove wear under long-term high-speed friction conditions, leading to scratches on the copper wire surface and cross-sectional deformation; the lack of wear self-adaptive compensation mechanisms between multi-stage wheel systems means that excessive local wear can exacerbate tension imbalance, significantly increasing the risk of wire breakage. Therefore, we propose a multi-stage guide wheel wear-resistant system for shaped copper monofilament drawing lines. Utility Model Content

Example
[0019] A multi-stage guide wheel wear-resistant system for irregularly shaped copper monofilament drawing wire, such as Figures 1-4 As shown, a drawing machine 1 has a mounting base 101 fixedly installed on its top. The top of the mounting base 101 has a transverse groove and a longitudinal groove. A drawing device 13 is rotatably installed on the top of the mounting base 101. An adjusting device 2 for adjusting the tension of the copper wire is provided on the top of the mounting base 101. The adjusting device 2 includes a pressure sensor 21, a pressure receiving component 22, a connecting plate 23, and a pressure roller 24. The pressure sensor 21 is fixedly installed on the outer wall of the drawing device 13. The pressure receiving component 22 is slidably installed on the output end of the pressure sensor 21. The connecting plate 23 is fixedly installed on the outer wall of the pressure receiving component 22. The pressure roller 24 is rotatably installed on the inner wall opposite to the connecting plate 23 via a rotating shaft.
[0020] The mounting base 101 has a figure-nine design. A wire feeding roller 102 is fixedly installed on the top left end of the drawing machine 1, and a wire take-up roller 103 is fixedly installed on the top right end of the drawing machine 1. A straightener 11 is fixedly installed on the top of the drawing machine 1 near the wire feeding roller 102, and a wire winding drum 12 is fixedly installed on the top of the drawing machine 1 near the straightener 11.
[0021] The adjusting device 2 also includes a wire 25, a servo motor 26, a ball screw 27, a screw nut 28, a tension wheel 29, a rotating rod 210, a conical gear 211, a second ball screw 212, a second conical gear 213, a second screw nut 214, a L-shaped bracket 215, a guide wheel 216, and a nickel-coated frame 217. One end of the wire 25 is electrically connected to the tail of the pressure sensor 21, and the servo motor 26 is electrically connected to the other end of the wire 25. The ball screw 27 is fixedly installed at the output end of the servo motor 26, the screw nut 28 is threadedly connected to the outer wall of the ball screw 27, and the tension wheel 29 is rotatably installed on the screw nut 28. At the top of 28, the rotating rod 210 is fixedly installed at the end of the ball screw 27 away from the servo motor 26, the conical tooth 211 is fixedly installed on the outer wall of the rotating rod 210, the ball screw 212 is rotatably installed on the inner wall of the longitudinal groove of the mounting base 101 through the bracket plate, the conical tooth 213 is fixedly installed on the outer wall of the ball screw 212 near the conical tooth 211, the screw nut 214 is threadedly connected to the outer wall of the ball screw 212, the four-shaped bracket 215 is fixedly installed on the top of the screw nut 214, the guide wheel 216 is rotatably installed on the inner wall of the four-shaped bracket 215, and the nickel coating 217 is applied to the surface of the guide wheel 216.
[0022] The servo motor 26 is fixedly installed on the top of the drawing machine 1 near the mounting base 101, and the servo motor 26 is driven by the pressure sensor 21 connected by the wire 25. The lead screw nut 28 is slidably installed on the inner wall of the transverse groove of the mounting base 101. The conical tooth 213 meshes with the conical tooth 211. There are two guide wheels 216. The nickel coating 217 is in contact with the surface of the copper wire.
[0023] In use, the multi-stage guide wheel wear-resistant system for drawing irregularly shaped copper monofilaments involves passing the copper wire sequentially through a straightener 11, a winding drum 12, a tensioning wheel 29, a guide wheel 216, a pressure roller 24, and an irregularly shaped drawing die 15 on the drawing device 14. The wire is then fixed on a take-up roller 103. When the take-up roller 103 is activated, it drives the copper wire to wind up. The copper wire is then cold-drawn through the irregularly shaped drawing die 15. However, the fixed guide wheel 216 is prone to groove wear under long-term high-speed friction conditions, resulting in scratches and deformation on the surface of the irregularly shaped copper wire. Therefore, when the copper wire passes through the pressure roller 24, the pressure roller 24 acts on the pressure-receiving component 22 on the connecting plate 23. The pressure-receiving component 22 converts the mechanical pressure change into an electrical signal and transmits it to the pressure sensor 21, allowing the pressure sensor 21 to monitor the tension parameters of the copper wire in real time.
[0024] When the detected tension value exceeds the preset range, such as >300N or <180N, the pressure sensor 21 sends an electrical signal to the servo motor 26 through the wire 25. The servo motor 26 drives the ball screw 27 to rotate, and the ball screw 27 drives the screw nut 28 to move laterally along the inner wall of the mounting base 101. The screw nut 28 drives the tension wheel 29 to generate lateral displacement. The tension fluctuation is dynamically compensated by changing the wrap angle of the copper wire between the tension wheel 29 and the winding drum 12. Simultaneously, the ball screw 27 drives the rotating rod 210 to rotate, which in turn drives the first conical tooth 211 to rotate. The first conical tooth 211 meshes with the second conical tooth 213 on the second ball screw 212, causing the second conical tooth 213 to drive the second ball screw 212 to rotate on the inner wall of the mounting base 101. The second ball screw 212 drives the second screw nut 214 to slide on the inner wall of the longitudinal groove of the mounting base 101. The second screw nut 214 drives the L-shaped bracket 215 to slide longitudinally, and the L-shaped bracket 215 drives the guide wheel. The longitudinal sliding of 216 and the left-right sliding of the guide wheel 216, combined with the high hardness and wear resistance of the nickel coating 217, allow the contact position of the copper wire to be continuously and dynamically adjusted during the guiding process. This avoids localized repeated friction that can cause groove wear, protects the integrity of the nickel coating 217 surface to maintain a low coefficient of friction, and significantly extends the service life of the guide wheel through the uniform distribution of the wear area. This effectively prevents scratches and deformation on the surface of irregularly shaped copper wires under high-speed winding conditions, ensuring the stability of the tension compensation system and the surface quality of the product.
