Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a wire drawing machine with excellent cooling performance. Background Art

[0002] Due to the rapid development of the wire and cable industry, the demand and requirements for the cross-sectional shape, surface accuracy and diameter of the conductor are getting higher and higher. The wire drawing machine is used to draw the rods or wires produced by the manufacturer into wires that meet the required diameter. The wire drawing machine is obtained by passing the rods through the wire drawing die and compressing them. For example, the Chinese patent with publication number CN210497692U discloses a wire drawing machine, including a wire drawing machine body, a feed hole and a discharge hole are respectively opened on both sides of the wire drawing machine body, and also includes a rotating disk rotatably connected to the side of the wire drawing machine body close to the discharge hole, and a positioning rod for positioning the rotation angle. The rotating disk is provided with a plurality of non-completely fixed grooves along its circumference, and a wire drawing die matching the fixed groove is fixed in the fixed groove. The wire drawing die is provided with a wire drawing hole, and the wire drawing hole is coaxial with the discharge hole. One end of the positioning rod is plugged into the rotating disk, and the other end is penetrated through the side wall of the wire drawing machine body, and the rotating disk can rotate synchronously with the positioning rod.

[0003] Because there is friction between the rod and the wire drawing die when it passes through the die, the existence of friction not only causes serious wear of the die hole of the wire drawing die, but also causes the temperature of the wire drawing die to rise rapidly. The traditional way is to use lubricating fluid for lubrication and cooling at the same time, but the cooling effect is poor. For this reason, we propose a wire drawing machine with excellent cooling performance to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Reference Figure 1 , 2 , which is the first embodiment of the utility model, and this embodiment provides a wire drawing machine with excellent cooling performance, including a base plate 1, a cooling water circulation machine 2 is fixedly installed on one side of the top of the base plate 1, the middle of the top of the base plate 1 is fixedly connected to the lower mounting seat 4, an upper mounting seat 5 is provided on the top of the lower mounting seat 4, a mold core 9 is sleeved between the upper mounting seat 5 and the lower mounting seat 4, and brackets 3 fixed to the base plate 1 are respectively provided on both sides of the upper mounting seat 5 and the lower mounting seat 4, a guide roller 7 is rotatably installed on the top of the bracket 3, and cooling spiral pipes 6 are fixedly installed in the upper mounting seat 5 and the lower mounting seat 4.

[0020] The cooling water circulation machine 2 is connected to the cooling spiral tube 6 through a water pipe to provide coolant to the cooling spiral tube 6. By opening the upper mounting seat 5, the internal mold core 9 can be easily replaced. The guide roller 7 guides the wire drawing material to ensure smoothness during wire drawing. The coolant flowing inside the cooling spiral tube 6 cools the wire drawing process and improves the cooling effect during wire drawing. At the same time, the arc tube 8 sprays lubricating liquid to lubricate the wire drawing work and reduce the wear of the mold core 9.

[0021] Example 2: Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. Specifically, the two ends of the lower mounting seat 4 are respectively fixedly connected to the lower mounting plate 41, and the two ends of the upper mounting seat 5 are respectively fixedly connected to the upper mounting plate 51. The upper mounting plate 51 passes through a long bolt and cooperates with the threaded hole opened on the lower mounting plate 41 to achieve fixed covering between the lower mounting seat 4 and the upper mounting seat 5.

[0022] Specifically, the upper mounting seat 5 and the lower mounting seat 4 are arranged opposite to each other, and arc-shaped openings 10 are respectively opened at both ends of the upper mounting seat 5 and the lower mounting seat 4. The arc-shaped openings 10 opened by the upper mounting seat 5 and the lower mounting seat 4 are combined to form a complete circular opening, thereby facilitating the passage of materials.

[0023] Furthermore, an arc tube 8 is provided at the bottom of one end of the upper mounting seat 5, and the arc tube 8 is fixedly installed in the arc mouth 10. A plurality of nozzles 82 are fixedly installed on the arc tube 8, and the nozzles 82 are evenly distributed. One end of the upper mounting seat 5 is fixedly connected to a connecting tube 2 81, and the connecting tube 2 81 is connected to the arc tube 8. The connecting tube 2 81 cooperates with the pipeline to connect the lubricating oil and the pump body to provide lubricating liquid to the inside of the arc tube 8. The lubricating liquid is finally sprayed out through the nozzle 82 to lubricate the wire drawing material. At the same time, the lubricating oil slides along the outer wall of the wire drawing material under the action of gravity, and then wraps the entire wire drawing material to ensure the lubrication effect.

[0024] Specifically, both sides of the top of the upper mounting seat 5 are fixedly connected with connecting pipes 61, which are connected to the cooling water circulation machine 2 through a pipeline, and are fixedly connected to both ends of the cooling spiral tube 6.

[0025] Specifically, the cooling spiral tube 6 is fixedly installed in the upper mounting seat 5 and the lower mounting seat 4 respectively. The cooling spiral tube 6 forms a complete spiral structure through the plug-in component 1 62 and the plug-in component 2 63. The plug-in component 1 62 includes a support frame 1 621, a slide bar 622, a spring 623, a sealing plate 624, and a plug-in tube 625. The plug-in tube 625 is fixedly installed in the upper mounting seat 5. The plug-in tube 625 is fixedly connected to the support frame 1 621. The support frame 1 621 is slidably sleeved on the slide bar 622. The bottom end of the slide bar 622 is fixedly connected to the sealing plate 624. The outer diameter of the sealing plate 624 is larger than the inner diameter of the end opening of the plug-in tube 625. A spring 623 is movably sleeved outside the slide bar 622. One end of the spring 623 is fixedly connected to the sealing plate 624, and the other end of the spring 623 is fixedly connected to the support frame 1 621. The inner diameter of the plug-in tube 625 is larger than the inner diameter of the end opening.

[0026] Furthermore, the plug-in assembly 63 includes a connector 631, a support frame 632, and a push rod 633. The connector 631 is plugged into the plug-in tube 625. The connector 631 is fixedly connected to the support frame 632. One end of the support frame 632 is fixedly connected to the push rod 633. The end of the push rod 633 away from the support frame 632 is in contact with the sealing plate 624.

[0027] When the upper mounting seat 5 is combined with the lower mounting seat 4, the plug-in component 1 62 and the plug-in component 2 63 arranged on both sides of the core cavity are plugged into each other, the plug-in tube 625 is inserted into the connector 631, and the end of the push rod 633 abuts against the sealing plate 624, and the spring 623 is compressed at the same time. The sealing plate 624 is away from the internal intersection of the plug-in tube 625, and a gap is left between the outer wall of the sealing plate 624 and the inner wall of the plug-in tube 625, so that the end opening of the plug-in tube 625 is connected to the interior to ensure the smooth circulation of the coolant. When the core 9 needs to be replaced, the upper mounting seat 5 is removed, and the plug-in tube 625 is separated from the connector 631. The sealing plate 624 is pressed down by the elastic force of the spring 623, and the sealing plate 624 then seals the inside of the plug-in tube 625 to prevent the coolant in the cooling spiral tube 6 in the lower upper mounting seat 5 from leaking.

[0028] Example 3: Reference Figure 1-4 , which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When in use, the cooling water circulation machine 2 is connected to the cooling spiral tube 6 through a water pipe to provide cooling liquid to the cooling spiral tube 6. By opening the upper mounting seat 5, it is convenient to replace the internal mold core 9. When the upper mounting seat 5 is combined with the lower mounting seat 4, the plug-in component 1 62 and the plug-in component 2 63 arranged on both sides of the mold core chamber are plugged and matched, and the plug-in tube 625 is inserted into the connector 631. The end of the ejector rod 633 abuts against the sealing plate 624, and the spring 623 is compressed at the same time. The sealing plate 624 is away from the internal intersection of the plug-in tube 625. A gap is left between the outer wall of the sealing plate 624 and the inner wall of the plug-in tube 625, so that the end opening of the plug-in tube 625 is connected to the interior to ensure the smooth circulation of the coolant. When needed Replace the core 9, remove the upper mounting seat 5, and detach the plug tube 625 from the connector 631. The elastic force of the spring 623 presses the sealing plate 624 downward, and the sealing plate 624 then seals the inside of the plug tube 625 to prevent leakage of the coolant in the cooling spiral tube 6 in the lower mounting seat 5. The guide roller 7 guides the wire drawing material to ensure smoothness during wire drawing. The coolant flowing inside the cooling spiral tube 6 cools the wire drawing process and improves the cooling effect during wire drawing. The connecting pipe 81 cooperates with the pipeline to connect the lubricating oil and the pump body to provide lubricating liquid to the inside of the arc tube 8. The lubricating liquid is finally sprayed out through the nozzle 82 to lubricate the wire drawing material. At the same time, the lubricating oil slides along the outer wall of the wire drawing material under the action of gravity, and then wraps the entire wire drawing material, ensuring the lubrication effect and reducing the wear of the core 9.
