Description

Technical Field

[0001] The utility model relates to the technical field of copper wire processing, in particular to a large drawing device for purple copper wire. Background Technique

[0002] Copper wire is used as a conductor with good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc. It has good thermal conductivity and is often used to manufacture magnetic instruments and meters that prevent magnetic interference, such as compasses, aviation instruments, etc. It has excellent plasticity and is easy to be processed by hot pressing and cold pressing. It can be made into copper materials such as tubes, rods, wires, strips, tapes, plates, and foils. During the production process of copper wire, the raw materials are relatively thick, and a large wire drawing machine for copper wire is required for wire drawing production. Therefore, a large drawing device for purple copper wire needs to be designed.

[0003] The internal structure of the existing large drawing device is relatively simple, and most of them are not equipped with a wire feeding buffer mechanism. During the later wire drawing operation of copper wire, the pulling force with a large tension will cause the copper wire that has not entered the inside of the drawing machine to be tightened, resulting in tearing or breaking of the copper wire surface, affecting the wire drawing efficiency of the later drawing machine and the copper wire drawing production efficiency, reducing the smoothness of the later wire feeding. Finally, most of the wire feeding ends of the drawing machine are fixed and installed by screwing multiple groups of threads. This fixing method is relatively cumbersome and reduces the disassembly and assembly efficiency of later operators, thus affecting the later wire drawing efficiency. Content of the Utility Model

[0027] The engaging assembly includes second springs 11, through grooves 12, connecting rods 13, limiting collar rings 14 and clamping rods 17. There are two groups of through grooves 12. The two groups of through grooves 12 are opened at the top and bottom of the inside of the mounting roller 10, and the through grooves 12 communicate with the inside of the mounting roller 10. A connecting rod 13 is jointly penetrated through one end of the two groups of through grooves 12 close to the rotating rod 16.

[0033] Working principle: During use, the device can be first transported to a designated position and powered on. Then, the wire feeding roller 6 of the copper wire raw material is placed at one end of the two groups of mounting rollers 10 close to each other. At the same time, the limiting collar 14 can be held to drive the connecting rod 13 to move inside the mounting roller 10 through the through groove 12, so as to compress the second spring 11. Then, the clamping rod 17 is driven by the movement of the connecting rod 13 to be received inside the mounting roller 10. When the wire feeding roller 6 is placed at one end of the two groups of mounting rollers 10 close to each other, the wire feeding roller 6 can drive the rotating rod 16 to align with the mounting roller 10. Then, the limiting collar 14 is released. Through the elastic restoring force of the second spring 11, the limiting collar 14 and the connecting rod 13 can be restored simultaneously, so that the limiting collar 14 can be sleeved outside the rotating rod 16 and the mounting roller 10 to complete a fixing operation. Then, through the restoration of the connecting rod 13, the clamping rod 17 can be pushed into the inside of the clamping groove 15 to perform a secondary fixing on the alignment of the rotating rod 16 and the mounting roller 10, and then the fixed installation work of the wire feeding roller 6 can be completed. There is no need for the operator to perform multiple sets of thread screwing operations, which improves the disassembly and assembly efficiency of the wire feeding roller 6 during wire drawing by the wire drawing mechanism 9 in the later stage, so as to improve the working efficiency of the wire drawing mechanism 9;

[0034] During the wire drawing process of the wire drawing mechanism 9, the copper wire wound around the outside of the wire feeding roller 6 can be wound around the outside of the fixed roller 8 and the buffer roller 3 as shown, and then passed into the inside of the wire drawing mechanism 9 to perform wire drawing operations. At the same time, the pulling force generated during wire drawing can make the copper wire drive the buffer roller 3 to move inside the sliding groove 2, realizing the compression operation of the first spring 7. Then, through the movement of the buffer roller 3 and the compression of the first spring 7, a certain buffer can be achieved for the pulling force of the copper wire, effectively preventing the copper wire from being torn or broken by a large pulling force, and ensuring the wire drawing quality and efficiency in the later stage.
