Description

Technical Field

[0001] This utility model mainly relates to the field of cable production, specifically to an energy-saving wire drawing machine for adaptive tension adjustment of plastic insulated control cables. Background Technology

[0002] In the wire and cable manufacturing industry, the wire drawing machine is a key piece of equipment that passes metal rods such as copper and aluminum through a series of gradually decreasing die holes, stretching them under external force to reduce their cross-section and increase their length, thus obtaining the required wire diameter. The metal wire produced is the core conductor in the manufacture of various plastic-insulated control cables, and its quality directly affects the electrical and mechanical properties of the cables.

[0003] The wire drawing process is essentially a metal plastic deformation process, which generates enormous friction and heat. If these forces and heat are not effectively controlled, a series of serious problems will occur: scratches on the wire surface, burrs, wire breakage, abnormal die wear, and even die breakage, ultimately resulting in decreased product quality, reduced production efficiency, and increased production costs. Therefore, lubrication plays a crucial role in this process. Its core function is to form a strong and continuous protective film between the metal wire and the inner hole of the die to minimize friction, dissipate deformation heat, ensure the smoothness of the wire surface, and extend the service life of the die.

[0004] During the operation of specific embodiments, the inventors discovered the following defects: To ensure even the minimum lubrication effect, circulating spray systems often employ a "better too much than too little" strategy, with water or oil pumps continuously operating at high power to spray excess lubricant onto the wire and mold. This not only consumes a significant amount of electrical energy but also results in a huge consumption of the lubricant itself (as a chemical product). Excess lubricant causes direct economic losses and environmental burdens during splashing, dripping, evaporation, and subsequent filtration, cooling, and recycling processes.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: an energy-saving wire drawing machine for adaptive tension adjustment of plastic insulated control cables, comprising a cable stretching structure, a cable guide structure provided at the top of the cable stretching structure, and a wire drawing structure provided on one side of the top of the cable stretching structure; A cable guiding structure includes a mounting plate, a guide block on the top of the mounting plate, an outlet inside the guide block, and a diversion pipe on the top of the guide block.

[0008] Furthermore, the cable tensioning structure includes a housing, a lubrication chamber is provided inside the housing, a water trough is provided on both sides of the top of the housing, the water trough is connected to the lubrication chamber, and baffles are provided on both sides of the top of the housing.

[0009] Furthermore, side plates are provided on both sides of the housing, a servo motor is provided at the bottom of the side plates, a rotating bar is provided at the output end of the servo motor, rotating wheels are rotatably connected to both sides of the rotating bar, and a first wire feeding groove is provided on the outer wall of the rotating wheel.

[0012] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This invention involves passing the cable sequentially through a guide block and an arc-shaped plate and winding it around. The outer wall of the cable then adheres to the guide block and the arc-shaped plate, and the cable sequentially adheres to the outer wall of the second cable-laying groove. During the cable drawing process, the pump body sends lubricant into the interior of the distribution pipe, and then the lubricant is discharged from the outlet and comes into contact with the cable. Multiple outlets can evenly coat the surface of the cable with lubricant, preventing the cable from overheating during the drawing process. Meanwhile, excess lubricant is recycled back into the lubrication chamber through the lower water tank. Attached Figure Description

[0019] See attached document Figure 1-3 An energy-saving wire drawing machine for adaptive tension adjustment of plastic insulated control cables includes a cable stretching structure 1, a cable guide structure 2 is provided on the top of the cable stretching structure 1, and a wire drawing structure 3 is provided on one side of the top of the cable stretching structure 1. The cable guiding structure 2 includes a mounting plate 201. A guide block 206 is positioned on the top of the mounting plate 201. An outlet 205 is provided inside the guide block 206. A diversion pipe 207 is positioned on the top of the guide block 206. Multiple guide blocks 206 are included, and an arc-shaped plate 204 is positioned between two guide blocks 206. Rotating wheels 202 are rotatably connected to both sides of each guide block 206. A second cable feeding groove 203 is provided on the outer wall of each rotating wheel 202. The cable to be drawn is sequentially wound in a U-shape around the guide block 206 and the outer wall of the arc-shaped plate 204. The cable is attached to the guide block 206 and the arc plate 204, and to the inner wall of the second cable tray 203. As the cable moves forward, it slides on the outer wall of the second cable tray 203, the arc plate 204 and the guide block 206. A pump body is installed inside the lubrication chamber 102. When the pump body is started, the pump body sends the lubricating liquid inside the lubrication chamber 102 into the inside of the diversion pipe 207. Then the lubricating liquid is discharged through the outlet 205, so that the lubricating liquid comes into contact with the outer wall of the cable to lubricate the cable. Excess lubricating liquid or lubricating liquid dripping from the surface of the cable re-enters the inside of the lubrication chamber 102 through the drain trough 103 for lubrication.

[0020] Furthermore, the cable stretching structure 1 includes a housing 101, with a lubrication chamber 102 inside the housing 101. Water channels 103 are provided on both sides of the top of the housing 101, connected to the lubrication chamber 102. Baffles 104 are provided on both sides of the top of the housing 101, and side plates 105 are provided on both sides of the housing 101. A servo motor 106 is provided at the bottom of the side plate 105. A rotating bar 107 is provided at the output end of the servo motor 106. Rotating wheels 108 are rotatably connected to both sides of the rotating bar 107. A first cable feeding groove 109 is provided on the outer wall of the rotating wheel 108. When… When drawing plastic-insulated control cables using a wire drawing machine, multiple cables are sequentially passed through the bottom of the first wire feeding groove 109 on the outermost rotating wheel 108. The cables are then moved and wound around the top of the first wire feeding groove 109 on the outermost rotating wheel 108. After that, the cables are wound inside the cable guide structure 2, and the cables slide inside the first wire feeding groove 109. At the same time, when the cables are loosened, the servo motor 106 is started. The servo motor 106 drives the rotating bar 107 to rotate, and the rotating bar 107 drives the rotating wheel 108 to rotate, causing the rotating wheel 108 to rotate the cable, thereby stretching the cable and making it taut.

[0021] Furthermore, the wire drawing structure 3 includes a wire drawing plate 301, which is disposed in the middle of one side of the top of the housing 101. A wire drawing groove 302 is provided inside the wire drawing plate 301. The cable passes through the wire drawing groove 302, which squeezes the cable, thereby changing the size of the cable and drawing it into wires.

[0022] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
