Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel cord production technology, and more specifically to a pitched idler roller for copper-plated steel wire. Background Technology
[0002] In a copper-plated steel wire electroplating production line, multiple copper-plated steel wires are electroplated simultaneously. The spacing rollers can maintain a suitable distance between each copper-plated steel wire, allowing it to run stably in the plating bath. The rollers guide the steel wires through the plating bath along a predetermined route, ensuring that the steel wires are evenly immersed in the plating solution and avoiding contact or tangling with each other. This results in a uniform plating layer and ensures the smooth progress of the electroplating process.
[0003] In current electroplating production lines, stainless steel plates are typically grooved and spaced. Due to the sliding friction between the stainless steel plate and the copper-plated steel wire, the surface hardness of the copper-plated steel wire is lower than that of the stainless steel plate. Therefore, when it comes into contact with the stainless steel plate, it is easy to scratch the surface of the steel wire, causing the steel wire to rub, which is not conducive to improving production quality. Summary of the Invention
[0004] To address the technical problems existing in existing idler rollers, the first aspect of this utility model proposes a spacing idler roller specifically for copper-plated steel wire, comprising:
[0005] The idler body has multiple grooves arranged at predetermined intervals on its outer wall. The grooves are used to support steel wires and to ensure that the multiple steel wires are spaced at predetermined intervals. The inner wall of the idler body has a first shaft hole and a second shaft hole.
[0006] A support shaft is connected to a first shaft hole in the inner wall of the roller body;
[0007] A bushing is connected to a second shaft hole on the inner wall of the idler roller body;
[0008] The hardness of the roller body and bushing is less than that of the support shaft, and the hardness of the roller body is less than that of copper.
[0009] Preferably, the Shore hardness of the idler roller body is less than 70.
[0010] Preferably, the first shaft hole is located at the center of the length direction of the roller body, and the second shaft hole is located at both ends of the length direction of the roller body.
[0011] Preferably, the length ratio of the first shaft hole to the second shaft hole is 8:2 to 9:1.
[0012] Preferably, the outer diameter of the first shaft hole is larger than the outer diameter of the second shaft hole.
[0013] Preferably, the support shaft is constructed as a hollow cylindrical structure, and the inner diameter of the support shaft is less than or equal to the inner diameter of the bushing.
[0014] Preferably, the groove is a V-shaped groove.
[0015] Preferably, the bottom of the groove is designed with rounded corners, and the angle of the groove is 30 to 60 degrees.
[0016] Preferably, the roller body and the bushing are both made of high-density polyethylene.
[0017] Preferably, the support shaft is a 316 stainless steel tube.
[0018] Compared with the prior art, the advantages of this utility model are:
[0019] The spacing idler roller of this utility model adopts a composite splicing structure. The outer layer is made of plastic material with a hardness lower than copper, and the inner layer is reinforced with stainless steel tube to meet the strength requirements. At the same time, the polymer material has a long service life and can be used for a long time by immersing in copper sulfate solution without damaging the surface of the steel wire. This effectively controls the production quality of copper-plated steel wire. The bushing structure at both ends can be replaced according to the wear condition. This structural design is not only conducive to assembly, but also facilitates the replacement of vulnerable parts, reducing the cost of use. Attached Figure Description

[0026] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.
[0027] Combination Figure 1 as well as Figure 2 , Figure 3 As shown, the first aspect of this utility model proposes a spacing idler 100 for copper-plated steel wire, including an idler body 110, a support shaft 120, and a bushing 130.
[0028] Combination Figure 1 and Figure 2 As shown, the outer wall of the roller body 110 is provided with a plurality of grooves 111 arranged at a predetermined interval. The grooves 111 are used to support the steel wires and to ensure that the multiple steel wires have a predetermined interval between them.
[0029] The idler roller 100 has a rotating shaft 200 at both ends, which is connected to the bearing 300, allowing the idler roller 100 to rotate freely. Multiple steel wires 400 pass around the idler roller 100 and are limited and spaced by the groove 111 on the idler roller 100.
[0030] In an optional embodiment, combined with Figures 4 to 5 As shown, groove 111 is a V-shaped groove.
[0031] Preferably, the bottom of the groove 111 is designed with rounded corners, and the angle A of the groove 111 is 30~60 degrees.
[0032] In this way, the steel wire can pass smoothly through the groove 111 without easily causing wear on the groove 111.
[0033] Specifically, the inner wall of the roller body 110 is provided with a first shaft hole 114 and a second shaft hole 113.
[0034] Combination Figure 3 As shown, the support shaft 120 is connected to the first shaft hole 114 on the inner wall of the roller body 110, and the bushing 130 is connected to the second shaft hole 113 on the inner wall of the roller body 110. The hardness of the roller body 110 and the bushing 130 is less than the hardness of the support shaft 120, and the hardness of the roller body 110 is less than the hardness of copper.
[0035] Thus, since the hardness of the roller body 110 is less than that of copper, the copper-plated steel wire will not be scratched when it passes through the roller body 110, resulting in a good coating on the surface of the steel wire.
[0036] Preferably, the Shore hardness of the idler body 110 is less than 70. In an optional embodiment, both the idler body 110 and the bushing 130 are made of high-density polyethylene.
[0037] Furthermore, the first shaft hole 114 is located at the center of the length direction of the roller body 110, and the second shaft hole 113 is located at both ends of the length direction of the roller body 110.
[0038] Thus, by setting a support shaft 120 inside the roller body 110, the strength of the roller body 110 can be guaranteed, and deformation and bending can be avoided during long-term support.
[0039] Preferably, the length ratio of the first shaft hole 114 to the length of the second shaft hole 113 is 8:2 to 9:1.
[0040] The outer diameter of the first shaft hole 114 is larger than the outer diameter of the second shaft hole 113. As a result, the bushing 130 inserted into the first shaft hole 114 is thicker, which avoids the need to replace it in a shorter cycle after wear with the rotating shaft 200. By increasing the thickness of the bushing 130, the replacement cycle of the bushing 130 can be extended.
[0041] Specifically, when it is necessary to replace the bushing 130, tap the bushing 130 from one end. At this time, the bushing 130 at the other end will come off. Then, use a tool to tap the support shaft 120 from the end where the bushing 130 was removed until the bushing 130 at the other end also comes off. Then replace it with a new pair of bushings 130 and re-embed them into the first shaft hole 114.
[0042] Optionally, the support shaft 120 is constructed as a hollow cylindrical structure, and the inner diameter of the support shaft 120 is less than or equal to the inner diameter of the bushing 130.
[0043] It should be understood that the support shaft 120 is provided in the second shaft hole 113 to increase the strength of the idler body 110, especially to prevent the idler body 110 from bending off the axis. Therefore, the support shaft 120 is made of thin-walled steel pipe to provide complete reinforcement.
[0044] Preferably, the support shaft 120 is made of 316 stainless steel pipe.
[0045] In conjunction with the above embodiments, the spacing idler roller of this utility model adopts a composite splicing structure. The outer layer is made of plastic material with a hardness lower than that of copper, and the inner layer is reinforced with stainless steel tube to meet the strength requirements. At the same time, the polymer material has a long service life and can be used for a long time by immersing in copper sulfate solution without damaging the surface of the steel wire. This effectively controls the production quality of copper-plated steel wire. The bushing structure at both ends can be replaced according to the wear condition. This structural design is not only conducive to assembly, but also facilitates the replacement of vulnerable parts and reduces the cost of use.
[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
