Detailed Implementation
[0016] 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.
[0017] Please see Figure 1-5This utility model provides a rotating die mechanism for a large copper and aluminum drawing machine, including a main sleeve 1. A drawing die 2 is provided in the middle of the interior of the main sleeve 1. An oil-immersing pipe 3 is provided inside the main sleeve 1 and on one side of the drawing die 2. A spacer pipe 4 is provided inside the main sleeve 1 and on the other side of the drawing die 2. A first limiting ring 5 and a second limiting ring 6 are respectively provided on both sides of the spacer pipe 4. A connecting sleeve 7 is provided on the outer side of the main sleeve 1 near the oil-immersing pipe 3. A first fixing ring 8 is provided on the outer side of the connecting sleeve 7. A third limiting ring 9 is provided between the outer side of the connecting sleeve 7 and the first fixing ring 8. A second fixing ring 10 is provided on the outer side of the main sleeve 1 near the second limiting ring 6.
[0018] In use, an oil-immersing pipe 3, a wire drawing die 2, a first limiting ring 5, a spacer tube 4, and a second limiting ring 6 are sequentially installed inside the main sleeve 1. A connecting sleeve 7 is installed at one end of the main sleeve 1 to fix one side of the main sleeve 1. A second fixing ring 10 is installed at the other end of the main sleeve 1 to fix the other end of the main sleeve 1. This clamps and fixes the structure inside the main sleeve 1, including the oil-immersing pipe 3, the wire drawing die 2, the first limiting ring 5, the spacer tube 4, and the second limiting ring 6. A first fixing ring 8 is used to fix the structure outside the connecting sleeve 7. The cable to be pulled first enters the main sleeve 1 through the third limit ring 9, and then enters the main sleeve 1 through the oil immersion pipe 3 to improve the lubrication of the cable. Then it enters the drawing die 2 to pull the cable. After the cable is pulled, it passes through the first limit ring 5 and the second limit ring 6 in sequence. The fixed pipe 4 is set between the first limit ring 5 and the second limit ring 6 to limit the distance between the first limit ring 5 and the second limit ring 6, and to limit the position of the cable to avoid friction between the cable and the main sleeve 1. Finally, the pulled cable is output.
[0019] The oil-immersed tube 3 is equipped with an oil-immersed sponge 11 inside. The side wall of the oil-immersed tube 3 is connected to the oil-immersed sponge 11 via an oil-filling pipe 12. The upper end of the main sleeve 1 is connected to the oil-filling pipe 12 via an oil-filling port 13. The inside of the connecting sleeve 7 is equipped with a fixing sleeve 14 at a position corresponding to the oil-immersed sponge 11. The fixing sleeve 14 abuts against the outside of the oil-immersed sponge 11. Lubricating oil is introduced into the oil-filling pipe 12 through the oil-filling port 13. The lubricating oil flows into the inside of the oil-immersed sponge 11 through the oil-filling pipe 12. The oil-immersed sponge 11 ensures that the lubricating oil is evenly applied to the cable. The fixing sleeve 14 is set on one side of the connecting sleeve 7 to clamp and fix the oil-immersed sponge 11.
[0020] The connecting sleeve 7 and the second fixing ring 10 clamp and fix the oil immersion tube 3, the wire drawing die 2, the distance tube 4, the first limiting ring 5 and the second limiting ring 6. The connecting sleeve 7 and the second fixing ring 10 clamp and fix the oil immersion tube 3, the wire drawing die 2, the first limiting ring 5, the distance tube 4 and the second limiting ring 6 inside the main sleeve 1.
[0021] The outer diameters of the main sleeve 1, the first fixing ring 8, and the second fixing ring 10 are the same. The outer diameter of the connecting sleeve 7 is larger than the outer diameter of the main sleeve 1. The outer edge of the connecting sleeve 7 extends to the outside of the main sleeve 1 to facilitate connection with the external bearing structure.
[0022] The first fixing ring 8 passes through the connecting sleeve 7 and is bolted to the main sleeve 1. The second fixing ring 10 is bolted to the main sleeve 1. The first fixing ring 8 and the connecting sleeve 7 are fixed to one side of the main sleeve 1 by bolts, and the second fixing ring 10 is fixed to the other side of the main sleeve 1.
