A lubricant replenishment and feeding mechanism for drawing copper wire

Abstract

This utility model relates to the field of copper wire production technology, specifically to a lubricant replenishment and feeding mechanism for drawing copper wire. It features a cylinder-driven piston plate that moves up and down within a lubricant storage tank. When the piston plate moves downwards, it increases the pressure within the storage tank, forcing lubricant to flow from the lower lubricant extrusion pipe onto the drawing roller, thus applying lubricant to the copper wire. As long as the cylinder-driven piston plate moves at a constant speed, the lubricant is ensured to be extruded at a uniform speed. When the cylinder-driven piston plate moves upwards, it reduces the pressure within the storage tank, thereby extracting lubricant. Therefore, a fixed amount of lubricant is applied and replenished in one cylinder cycle. The lubricant storage tank has multiple lubricant chambers, with the cylinder cycles for each chamber staggered to ensure that at any given time, at least one lubricant extrusion pipe is extruding lubricant to apply to the copper wire.

Description

Technical Field

[0001] This utility model relates to the field of copper wire production technology, and in particular to a lubricant replenishment and feeding mechanism for drawing copper wire. Background Technology

[0002] In mass production of copper wire, drawing is generally used. During the drawing process, intense plastic deformation occurs, and 90% of the deformation work is converted into heat energy, leading to an overall temperature rise. Furthermore, friction occurs as the copper wire passes through the die or roller, generating heat that further exacerbates the heating, sometimes reaching localized temperatures of 350–450°C in the die deformation zone. When the copper wire temperature exceeds 180°C, oxidation of the copper wire accelerates, conductivity decreases, and localized high temperatures increase the interatomic spacing, hindering electron migration and reducing conductivity. Therefore, it is essential to periodically apply lubricant to the copper wire during the drawing process. The lubricant not only reduces friction between the copper wire and the die or roller but also effectively cools the wire.

[0003] However, applying lubricant to copper wire is difficult to do evenly, often resulting in uneven application depending on the amount of lubricant available. Furthermore, the lubricant needs to be replenished promptly during the drawing process; failure to do so can negatively impact the quality of the copper wire.

[0004] Currently, lubricant replenishment is generally done manually or automatically via a pump. However, since lubricant is not applied at a uniform rate, neither method makes it easy to determine the lubricant level. Therefore, accurately replenishing lubricant based on its level becomes a problem when the lubricant application rate is uneven. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a lubricant replenishment and feeding mechanism for drawing copper wire, so as to solve the technical problem of how to accurately replenish lubricant according to the usage of lubricant in the prior art.

[0006] To achieve the above objectives, this utility model provides a lubricant replenishment and feeding mechanism for drawing copper wire, including a lubricant storage tank for temporarily storing lubricant for application and a mounting bracket for mounting the lubricant storage tank. The lubricant replenishment and feeding mechanism further includes:

[0007] Rotate the drawing wheel connected to the mounting bracket. Copper wire is wound on the drawing wheel. The lubricant storage tank is located above the drawing wheel, and the lower end of the lubricant storage tank is provided with a lubricant extrusion tube. The lower end of the lubricant extrusion tube is directed towards the center of the groove of the drawing wheel.

[0008] An inlet pipe connected to a lubricant storage tank is used to replenish and deliver lubricant. The lubricant storage tank is equipped with a piston plate, and the end port of the inlet pipe and the upper port of the lubricant extrusion pipe are both located below the piston plate.

[0009] Furthermore, a cylinder is also provided at the upper end of the lubricant storage tank, and the piston plate is fixedly connected to the output shaft of the cylinder;

[0010] Furthermore, the cylinder is fixedly connected to the lubricant storage tank via a cylinder bracket.

[0011] Furthermore, the lubricating fluid storage tank is fixedly connected to several partitions, which are arranged at equal intervals to divide the lubricating fluid storage tank into multiple lubricating fluid chambers. Each lubricating fluid chamber is slidably connected to a piston plate, and each lubricating fluid chamber is correspondingly equipped with a cylinder.

[0012] Furthermore, the inlet pipe is fixedly connected to the mounting bracket, and each lubricating fluid chamber is connected to a corresponding inlet pipe.

[0013] Furthermore, the lubricant extrusion pipe is equipped with an application valve, and the inlet pipe is equipped with a replenishment valve. Both the application valve and the replenishment valve are electromagnetic shut-off valves.

[0014] Furthermore, the application valve and the replenishment valve can also be configured as one-way valves, wherein the application valve only allows downward one-way communication, and the replenishment valve only allows inward one-way communication.

[0015] Furthermore, the drawing rollers are provided in a plurality of manner, and the copper wire being drawn is wound around each drawing roller at least once in sequence, and the number of drawing rollers is greater than the number of lubricant extrusion tubes.

[0016] The beneficial effects of this utility model are as follows: 1. A lubricant storage tank is provided to temporarily store the lubricant, preventing lubricant shortages. Additionally, a cylinder drives a piston plate to move up and down within the lubricant storage tank. When the piston plate moves downwards, it increases the pressure within the storage tank, forcing the lubricant to flow from the lubricant extrusion pipe below onto the drawing roller, thereby applying lubricant to the copper wire. Furthermore, as long as the cylinder-driven piston plate moves at a uniform speed, the lubricant can be extruded at a uniform speed.

[0017] 2. An inlet pipe is installed to replenish the lubricant storage tank, and the end of the inlet pipe is also located below the piston plate. Therefore, when the cylinder drives the piston plate to move upward, the pressure inside the lubricant storage tank can be reduced, thereby playing the role of extracting lubricant. Thus, a quantitative amount of lubricant is applied and replenished in one working cycle of the cylinder.

[0018] 3. A coating valve is installed on the lubricant extrusion pipe, and a replenishment valve is installed on the inlet pipe. Both the coating and replenishment valves can be electromagnetic shut-off valves. When the piston plate moves upward, the coating valve closes; when the piston plate moves downward, the replenishment valve closes, ensuring that the up and down movement of the piston plate can be used for both drawing and coating the lubricant. Alternatively, the coating and replenishment valves can also be designed as one-way valves, achieving the same effect.

[0019] 4. The lubricant storage tank is equipped with multiple lubricant chambers. Each lubricant chamber is equipped with a set of piston plates, cylinders, inlet pipes and lubricant extrusion pipes. The working cycles of different sets of cylinders are staggered to ensure that at any time, at least one lubricant extrusion pipe is extruding lubricant to coat the copper wire.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the application of lubricant is not always uniform, making it difficult to judge the lubricant usage whether it is replenished manually or automatically by a pump. This also makes it difficult to apply the lubricant evenly. Therefore, this invention designs a lubricant replenishment and feeding mechanism, including a lubricant storage tank 103 for temporarily storing the lubricant used for application and a mounting bracket 101 for mounting the lubricant storage tank 103.

[0031] Specifically, a drawing wheel 102 is rotatably connected to the mounting bracket 101. Copper wire 01 is wound on the drawing wheel 102. The lubricant storage tank 103 is located above the drawing wheel 102, and the lower end of the lubricant storage tank 103 is provided with a lubricant extrusion pipe 107. The lower end outlet of the lubricant extrusion pipe 107 faces the center of the groove of the drawing wheel 102.

[0032] The drawing rollers 102 are provided in several ways. The copper wire 01 being drawn is wound around each drawing roller at least once. The lubricant extrusion tubes 107 are also provided in several ways, but the number of drawing rollers 102 is greater than the number of lubricant extrusion tubes 107.

[0033] The lubricant storage tank 103 is also connected to the inlet pipe 106, which is used to replenish and deliver lubricant. The inlet pipe 106 is fixedly connected to the mounting bracket 101.

[0034] In addition, a piston plate 112 is provided inside the lubricant storage tank 103, and the end port of the inlet pipe 106 and the upper port of the lubricant extrusion pipe 107 are both located below the piston plate 112. A cylinder 105 is also provided at the upper end of the lubricant storage tank 103, and the piston plate 112 is fixedly connected to the output shaft of the cylinder 105.

[0035] The key point is that the lubricant extrusion pipe 107 is equipped with an application valve 108, and the inlet pipe 106 is equipped with a replenishment valve 109. Both the application valve 108 and the replenishment valve 109 are electromagnetic shut-off valves.

[0036] Preferably, the applicator valve 108 and the supplement valve 109 can also be configured as one-way valves, wherein the applicator valve 108 only allows downward one-way communication, and the supplement valve 109 only allows inward one-way communication.

[0037] The cylinder 105 drives the piston plate 112 to move up and down within the lubricant storage tank 103. When the piston plate 112 moves downward, it increases the pressure within the lubricant storage tank 103, forcing the lubricant to flow from the lubricant extrusion pipe 107 below onto the drawing roller 102, thereby applying lubricant to the copper wire 01. Moreover, as long as the cylinder 105 drives the piston plate 112 to move at a constant speed, the lubricant can be extruded at a constant speed.

[0038] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in order to ensure that at any time there is at least one lubricant extrusion tube 107 extruding lubricant to coat the copper wire 01.

[0039] Several partitions 110 are fixedly connected inside the lubricant storage tank 103. The partitions 110 are arranged at equal intervals, dividing the lubricant storage tank 103 into multiple lubricant chambers 111. A piston plate 112 is slidably connected in each lubricant chamber 111, and a cylinder 105 is correspondingly provided in each lubricant chamber 111. Therefore, each lubricant chamber 111 is connected to a liquid inlet pipe 106 and a lubricant extrusion pipe 107.

[0040] Each lubricant chamber 111 is equipped with a set of piston plates 112, cylinders 105, inlet pipes 106 and lubricant extrusion pipes 107, and the working cycles of different sets of cylinders 105 are staggered to ensure that at any time, at least one lubricant extrusion pipe 107 extrudes lubricant to coat the copper wire 01.

[0041] Each working cycle of cylinder 105 completes the application and replenishment of a fixed amount of lubricant. When cylinder 105 drives piston plate 112 to move upward, it can reduce the pressure in lubricant storage tank 103, thereby playing the role of extracting lubricant.

[0042] When the cylinder 105 drives the piston plate 112 to move downwards within the lubricant storage tank 103, it increases the pressure within the lubricant storage tank 103, forcing the lubricant to flow from the lubricant extrusion pipe 107 below onto the drawing roller 102, thereby applying lubricant to the copper wire 01. Moreover, as long as the cylinder 105 drives the piston plate 112 to move at a constant speed, it can ensure that the lubricant is extruded at a constant speed.

[0043] When the piston plate 112 moves upward, the application valve 108 closes; when the piston plate 112 moves downward, the replenishment valve 109 closes, ensuring that the vertical movement of the piston plate 112 can be used for both drawing and applying lubricant. Alternatively, the application valve 108 and the replenishment valve 109 can also be configured as one-way valves to achieve the same effect.

[0044] In summary, the beneficial effects of this utility model are as follows: A lubricant storage tank 103 is provided to temporarily store the lubricant, preventing lubricant shortages. Additionally, a cylinder 105 drives a piston plate 112 to move up and down within the lubricant storage tank 103. When the piston plate 112 moves downwards, it increases the pressure within the lubricant storage tank 103, forcing the lubricant to flow from the lubricant extrusion pipe 107 below onto the drawing roller 102, thereby applying lubricant to the copper wire 01. Furthermore, as long as the cylinder 105 drives the piston plate 112 to move at a uniform speed, the lubricant can be extruded at a uniform speed.

[0045] A liquid inlet pipe 106 is provided to replenish the lubricant storage tank 103 with lubricant, and the end of the liquid inlet pipe 106 is located below the piston plate 112. Therefore, when the cylinder 105 drives the piston plate 112 to move upward, the pressure inside the lubricant storage tank 103 is reduced, thereby drawing out the lubricant. Thus, a quantitative amount of lubricant is applied and replenished in one working cycle of the cylinder 105. A coating valve 108 is provided on the lubricant extrusion pipe 107, and a replenishment valve 109 is provided on the liquid inlet pipe 106. The coating valve 108 and the replenishment valve 109 can be electromagnetic shut-off valves. When the piston plate 112 moves upward, the coating valve 108 closes; when the piston plate 112 moves downward, the replenishment valve 109 closes, ensuring that the vertical movement of the piston plate 112 can be used for drawing out and applying lubricant respectively. Alternatively, the coating valve 108 and the replenishment valve 109 can also be set as one-way valves, achieving the same effect.

[0046] In addition, the lubricant storage tank 103 is provided with multiple lubricant chambers 111. Each lubricant chamber 111 is provided with a set of piston plates 112, cylinders 105, inlet pipes 106 and lubricant extrusion pipes 107. The working cycles of different sets of cylinders 105 are staggered to ensure that at any time, at least one lubricant extrusion pipe 107 is extruding lubricant to coat the copper wire 01.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
