Description

Technical Field

[0001] The utility model relates to the field of metal wire processing, in particular to a compact wire winding device for a copper wire drawing machine. Background Technique

[0002] In the metal wire processing industry, copper wire is one of the important raw materials, which is widely used in many fields such as wire and cable, electronic components, and construction. The production of copper wire usually includes multiple steps such as melting, casting, rolling, and wire drawing. Among them, wire drawing is one of the most critical processes. A copper wire drawing machine is a mechanical device specifically used for processing copper wire. It processes thicker copper wire rods into thinner copper wires through a series of physical processes. This device is widely used in industries such as wire and cable, electronic components, and construction.

[0003] The patent with the patent announcement number CN217726663U discloses a wire drawing machine for metal materials, including a wire drawing machine body. A wire drawing tower wheel and a driving roller are arranged on the wire drawing machine body. An unwinding roller is arranged on one side of the wire drawing tower wheel. A tensioning device for regulating the wire drawing tension is arranged between the unwinding roller and the wire drawing tower wheel. A lubricant adding tank is arranged downstream of the wire drawing tower wheel, and a heating device is arranged downstream of the lubricant adding tank. A wire diameter detecting device is arranged on one side of the driving roller. The above wire drawing machine fixes the metal wire through a tensioning seat, that is, the copper wire is clamped by using a wire clamp to squeeze the iron sheet to adjust the metal wire. This method may not provide enough clamping force for thicker copper wires, resulting in unstable clamping. Therefore, this wire clamp is only applicable to copper wires within a specific size range and lacks adaptability to copper wires of different diameters. Therefore, it is necessary to design a compact wire winding device for a copper wire drawing machine that is convenient for stable clamping in view of the shortcomings of the prior art. Content of the Utility Model

[0022] Embodiment: A tight wire winding device for a copper wire drawing machine, as Figures 1-4 shown, includes a frame 1, a servo motor 2, a wire reel 3, an annular plate 4, a lead screw 5, a guide rod 6, an extrusion rod 7, a linear motor 20, a cooling assembly, a mounting bracket 11, a clamping block 12, a limiting member, and a wire eye die 19. A servo motor 2 is installed on one side of the front part of the frame 1. The output shaft of the servo motor 2 is connected to the wire reel 3 through a coupling. A circle of annular plate 4 is fixedly connected to the side surface of the end of the wire reel 3 close to the servo motor 2. An insertion wire groove is formed on the annular plate 4. A lead screw 5 is rotatably installed on the annular plate 4. A guide rod 6 is also rotatably installed on the annular plate 4. An extrusion rod 7 is slidably connected to the guide rod 6. The extrusion rod 7 is in threaded connection with the lead screw 5. A through hole adapted to the extrusion rod 7 is formed on the annular plate 4. The extrusion rod 7 presses on the insertion wire groove to clamp and limit the inserted copper wire. A linear motor 20 is installed at the rear of the frame 1. A cooling assembly is arranged on the moving seat of the linear motor 20. A mounting bracket 11 is arranged on the side of the cooling assembly close to the wire reel 3. A clamping block 12 is fixedly connected to the mounting bracket 11. A wire eye die 19 is installed on the clamping block 12 through a limiting member. The wire eye die 19 is used to control the shape and size of the copper wire; the clamping end face of the extrusion rod 7 is chamfered, and the extrusion rod 7 is made of a high-strength and wear-resistant material.

[0023] As Figure 1 and Figure 3As shown, the cooling component includes a water tank 8, a rotating shaft 9 and a fixed pulley 10. The water tank 8 is installed on the moving seat of the linear motor 20. The water tank 8 is used to store coolant and lubricant. The rotating shaft 9 is rotatably installed on the opposite inner walls of the water tank 8 through bearings. Fixed pulleys 10 are symmetrically installed on both sides of the top of the water tank 8. The fixed pulleys 10 cooperate with the rotating shaft 9 to wind and stretch the copper wire. The fixed pulley 10 is detachably installed on the water tank 8, and the fixed pulley 10 can be replaced with a winding diameter adapted to the thickness of the current copper wire.

[0024] As Figure 4 and Figure 5 As shown, the limiting member includes a guide rod 121, a wedge block 17 and a second spring 18. A plurality of guide rods 121 are fixedly connected to the side of the block 12 close to the water tank 8. The guide rod 121 is of a hollow structure. The wire eye die 19 is slidably installed on the block 12 through the guide rod 121. Wedge blocks 17 are penetrated and slidably installed on the opposite inner side walls of the guide rod 121. The sides of the wedge blocks 17 facing away from the block 12 are inclined surfaces. Second springs 18 are provided between the wedge blocks 17 and the guide rod 121. Under the elastic force of the second spring 18, the wedge blocks 17 stably limit the wire eye die 19 on the block 12.

[0025] As Figure 3 and Figure 4 As shown, it further includes a push block 13, a connecting rod 14, a first spring 15 and a wedge rod 16. Connecting rods 14 are symmetrically fixedly connected to the side of the block 12 close to the wire reel 3. A push block 13 is slidably installed on the connecting rod 14. A first spring 15 is provided between the push block 13 and the connecting rod 14. Wedge rods 16 having the same number as the wedge blocks 17 are fixedly connected to the push block 13. The wedge rods 16 respectively penetrate through the block 12 and are located inside the guide rod 121. The wedge ends of the wedge rods 16 contact and penetrate through the wedge blocks 17. The push block 13 is a ring-shaped handle with an opening in the middle. The handle-shaped push block 13 is convenient for personnel to hold and push and pull.

[0026] When using this device, first add an appropriate amount of coolant and lubricant to the water tank 8. Then, for the copper wire to be drawn, after passing it around the rotating shaft 9 of one of the fixed pulleys 10, immerse the copper wire into the coolant and lubricant in the water tank 8. After cooling and lubricating, let the copper wire wind around another fixed pulley 10 and then pass through the wire eye die 19. Finally, insert the end of the copper wire into the wire slot of the annular plate 4. By turning the screw rod 5, the rotating screw rod 5 drives the extrusion rod 7 to move through the thread, and under the guidance of the guide rod 6, it correctly inserts into the through hole of the annular plate 4 and continuously clamps the copper wire in the wire slot of the annular plate 4. When the copper wire is completely clamped on the annular plate 4, the servo motor 2 can be activated. The output shaft of the servo motor 2 drives the wire winding drum 3 to rotate through the coupling. At this time, the moving seat of the linear motor 20 drives the water tank 8 to slide, so that the water tank 8 drives the copper wire on it to slide synchronously to adapt to the rotation of the wire winding drum 3 through the wire eye die 19, thereby tightly winding the copper wire around the wire winding drum 3. When it is necessary to replace the wire eye die 19 suitable for copper wires of different sizes, only need to push the push block 13 in the direction of the block 12. The pushed push block 13 will overcome the elastic force of the first spring 15 and drive the wedge-shaped rod 16 to move under the guidance of the connecting rod 14. At this time, the wedge-shaped block 17 in the guide rod 121 will retract into the guide rod 121 in the direction away from each other under the pressure of the wedge-shaped end of the wedge-shaped rod 16. At this time, the original wire eye die 19 can be slid out from the guide rod 121 of the block 12. After loosening the push block 13, the push block 13 drives the wedge-shaped rod 16 to reset under the action of the first spring 15 and no longer presses the wedge-shaped block 17. At this time, the newly replaced wire eye die 19 is pushed into and installed on the block 12 through the guide rod 121. After the wire eye die 19 touches the inclined surface of the wedge-shaped block 17, the wedge-shaped block 17 is pushed outwards. Finally, the wedge-shaped block 17 resets under the action of the second spring 18 and stably limits the newly installed wire eye die 19 on the block 12, thus achieving the effect of conveniently replacing the wire eye die 19.
