Description

Technical Field

[0001] This utility model relates to the field of cable processing and wire drawing technology, specifically a wire drawing device for processing steel-tape armored PVC sheathed power cables. Background Technology

[0002] Wire drawing machines, also known as wire drawing machines, are pre-processing equipment for the production of standard parts and other metal products. Their purpose is to draw wires or bars produced by steel manufacturers and transported to standard parts and other metal product manufacturers, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wires or bars meet the raw material processing requirements for the production of standard parts and other metal products.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] However, existing cable drawing devices generate a large amount of metal powder on the surface during the drawing process. The powder adheres to the surface of the metal wire, thereby reducing the usability of the processed metal wire. To remove the metal powder from the drawing surface, the metal wire is currently cleaned with cooling water to achieve both cleaning and cooling effects. However, due to the light weight of the powder, after water spraying and cleaning, a small amount of powder and water droplets may still adhere to the surface. After drying, these will form impurities that stick to the surface of the metal wire, thus reducing the efficiency of the cleaning process.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a wire drawing device for processing steel-reinforced PVC-sheathed power cables, so as to solve the problems mentioned in the background art.

[0007] By adopting the above technical solution, the problem of powder mixing with water and adhering to the surface of metal wire after water cleaning is solved, thus reducing the cleaning efficiency of wire drawing.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A wire drawing device for processing steel-reinforced PVC-sheathed power cables includes a base and a cable drawing body fixedly installed on the top of the base. A support frame located on the other side of a nozzle is fixedly installed on the top of the inner wall of the cable drawing body. A support rod is movably installed through the top and bottom of the support frame. A positioning pulley is fixedly installed at one end of the support rod that is close to each other. A spring located inside the support frame is sleeved on the outside of the support rod. An absorbent cotton cloth is sleeved on the outside of the positioning pulley. A blower is fixedly installed on the other side of the top of the cable drawing body. A cleaning ring is fixedly installed on the other side of the top of the inner wall of the cable drawing body. An air outlet is opened through the bottom of the cleaning ring. An air pipe extending into the cleaning ring is fixedly installed at the output end of the blower.

[0010] Preferably, a cable processing wire drawing tool is fixedly installed on one side of the top of the inner wall of the cable drawing body, a water supply pipe is fixedly installed through the top of the cable drawing body, and a nozzle is fixedly installed at the bottom of the water supply pipe.

[0011] Preferably, a winding roller located on one side of the cable drawing body is fixedly installed on one side of the top of the base, a collecting roller is fixedly installed on the other side of the top of the base, and a guide roller is rotatably installed on one side of the cable drawing body.

[0012] Preferably, a support frame located on one side of the collecting roller is fixedly installed on the other side of the top of the base. A lead screw is rotatably installed on the top of the support frame. A moving block is installed on the outside of the lead screw through a threaded connection. A guide hole is opened on the top of the moving block. A servo motor whose output end is connected to the front end of the lead screw through a hinge is fixedly installed on one side of the support frame.

[0013] Preferably, a fixing rod located at the bottom of the lead screw is fixedly installed on the inner side of the support frame, and a round hole is opened at the bottom of the moving block to fit onto the outside of the fixing rod.

[0014] Preferably, one side of the cable drawing body has an opening at the top of the guide roller, the other side of the cable drawing body has a wire outlet, and a water outlet pipe is fixedly installed through the bottom of the front end of the cable drawing body.

[0015] Compared with the prior art, this utility model provides a wire drawing device for processing steel-strip armored PVC sheathed power cables, which has the following beneficial effects: After the metal wire is drawn by the cable processing wire drawing device, the drawn metal wire is first cleaned by the water supply pipe and nozzle. Under the elastic force of the spring, the positioning pulley approaches and clamps the metal wire, so that the water-absorbing cotton cloth comes into contact with the surface of the metal wire and absorbs the moisture on the surface of the metal wire. Then, the blower and blower pipe blow air downwards, so that the small amount of powder remaining on the surface of the metal wire that has passed through the cleaning ring is blown off through the blower nozzle. This avoids the situation where the powder mixes with the water and sticks to the surface of the metal wire after the metal wire is cleaned with water, forming impurities and reducing the cleaning efficiency of the wire drawing process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a wire drawing device for processing steel strip armored PVC sheathed power cables.

[0024] Please see Figures 1-5 A wire drawing device for processing steel-reinforced PVC-sheathed power cables includes a base 1 and a cable drawing body 2 fixedly installed on the top of the base 1. A support frame 204 located on the other side of a nozzle 203 is fixedly installed on the top of the inner wall of the cable drawing body 2. A support rod 205 is movably installed through the top and bottom of the support frame 204. A positioning pulley 206 is fixedly installed at one end of the support rod 205 that is close to each other. A spring 207 located inside the support frame 204 is sleeved on the outside of the support rod 205. An absorbent cotton cloth 208 is sleeved on the outside of the positioning pulley 206. A blower 209 is fixedly installed on the other side of the top of the cable drawing body 2. A cleaning ring 211 is fixedly installed on the other side of the top of the inner wall of the cable drawing body 2. An air outlet 212 is opened through the bottom of the cleaning ring 211. An air pipe 210 extending into the cleaning ring 211 is fixedly installed at the output end of the blower 209.

[0025] With the above-described structural design, the wire drawing device for processing steel-strip armored PVC sheathed power cables cleans the metal wires after wire drawing. The wires are then clamped between positioning pulleys 206 by the elastic force of spring 207. The surface of the metal wires contacts the absorbent cloth 208, which absorbs the moisture. The wires then pass through the cleaning ring 211, and the blower 209 and blower pipe 210 blow away any remaining impurities. The impurities then fall through the blower nozzle 212 to the bottom of the cable drawing body 2 for collection. This avoids the situation where powder mixes with water and adheres to the surface of the metal wires after cleaning, forming impurities and reducing the efficiency of the wire drawing process.

[0026] Furthermore, a cable processing wire drawing tool 201 is fixedly installed on one side of the top of the inner wall of the cable drawing body 2. A water supply pipe 202 is fixedly installed through the top of the cable drawing body 2, and a nozzle 203 is fixedly installed at the bottom of the water supply pipe 202. After the cable wire is drawn by the cable processing wire drawing tool 201, cooling water is supplied through the water supply pipe 202 and sprayed out through the nozzle 203 to perform an initial cleaning treatment on the surface of the drawn wire, removing the processing metal powder adhering to the surface. This also cools the drawn wire. The cleaning wastewater falls to the bottom of the cable drawing body 2 and is collected, improving the performance of the cable wire and facilitating subsequent cleaning. This increases the cleaning efficiency of the wire and prevents impurities from remaining on the surface of the wire, thus avoiding any impact on its performance.

[0027] Furthermore, a winding roller 101 is fixedly installed on one side of the top of the base 1, located on one side of the cable drawing body 2, and a collecting roller 102 is fixedly installed on the other side of the top of the base 1. A guide roller 3 is rotatably installed on one side of the cable drawing body 2. The cable wire to be processed is installed on the outside of the winding roller 101, and the guide roller 3 guides the wire to extend into the interior of the cable drawing body 2 for processing. The collecting roller 102 winds and collects the processed wire, facilitating operation for workers.

[0028] Furthermore, a support frame 103 located on one side of the collecting roller 102 is fixedly installed on the other side of the top of the base 1. A lead screw 104 is rotatably installed on the top of the support frame 103. A moving block 105 is threadedly installed on the outer side of the lead screw 104. A wire guide hole 106 is opened on the top of the moving block 105. A servo motor 107 with its output end connected to the front end of the lead screw 104 via a hinge is fixedly installed on one side of the support frame 103. The servo motor 107 drives the lead screw 104 to reciprocate at a uniform speed, causing the moving block 105 to reciprocate back and forth on the surface of the lead screw 104. This allows the wire guide hole 106 to guide the drawn metal wire, thereby making the metal wire more evenly wound on the collecting roller 102 for collection.

[0029] Furthermore, a fixing rod 109 located at the bottom of the lead screw 104 is fixedly installed on the inner side of the support frame 103, and a circular hole 108 is provided at the bottom of the moving block 105 to fit onto the outside of the fixing rod 109. When the moving block 105 moves outside the lead screw 104, the circular hole 108 fits onto the outside of the fixing rod 109, thereby limiting the movement of the moving block 105 and preventing it from wobbling during movement.

[0030] Furthermore, one side of the cable drawing body 2 has an opening 213 located at the top of the guide roller 3, and the other side of the cable drawing body 2 has a wire outlet 214. A water outlet pipe 4 is fixedly installed through the bottom of the front end of the cable drawing body 2. The metal wire is guided and enters the interior of the cable drawing body 2 through the opening 213 for drawing processing. The processed metal wire is easily discharged and collected through the wire outlet 214. The wastewater containing metal powder inside the cable drawing body 2 is easily discharged and treated by opening the valve of the water outlet pipe 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
