Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing equipment, specifically a wire traction component for a dual-frequency micro wire drawing machine. Background Technology

[0002] The dual-frequency conversion micro-wire drawing machine is a specialized device that uses two frequency converters to control the stretching motor and the winding motor respectively, enabling step-by-step drawing and high-speed winding of metal wires or strips. The main frequency converter outputs a speed signal to the slave frequency converter, and PID adjustment compensates for changes in winding diameter to ensure matching of linear speed. It is suitable for the production of micro-wires with a wire diameter of 0.03-0.15mm, and the wire diameter uniformity can reach ±0.001mm. It is widely used in industries such as wire and cable, steel wire rope, and steel cord for processing metal wires such as copper, aluminum, and steel.

[0003] The wire traction component of a traditional dual-frequency micro wire drawing machine mainly achieves traction operation through traction rollers and auxiliary rollers. The traction roller is directly driven by a drive motor and its two ends are fixed by a mounting bracket. The two ends of the auxiliary roller are connected to the lead screw through adjustment blocks, which can achieve precise vertical adjustment. Its working principle is mainly to drive the traction roller to rotate through the drive motor, and cooperate with the auxiliary roller to perform traction operation on the wire.

[0004] However, the auxiliary rollers in traditional dual-frequency micro wire drawing machines lack flexible support. During high-speed wire drawing, the wire and the auxiliary roller surface will generate a large impact force. Due to the lack of flexible support in the auxiliary rollers, this impact force can easily cause the wire to break. Utility Model Content

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1-4 The present invention provides the following two preferred embodiments: Example 1: A wire traction assembly for a dual-frequency micro-drawing machine includes a mounting frame 1 and a mounting frame 2 5. The outer surface of mounting frame 1 has a mounting groove 1. An adjusting screw 2 is rotatably connected to the bottom of the inner cavity of mounting groove 1. An adjusting block 3 is threadedly connected to the outer wall of the adjusting screw 2. A mounting shaft 6 is rotatably connected to the outer surface of the adjusting block 3. A traction roller 7 is fixedly connected to the outer wall of the mounting shaft 6. The outer surface of mounting frame 1 has a mounting groove 2. A movable rod 16 is fixedly connected to the inner wall of mounting groove 2. A movable block 10 is slidably connected to the outer wall of the movable rod 16. A mounting shaft 2 8 is rotatably connected to the outer surface of the movable block 10. A mounting shaft 2 8 is fixedly connected to the outer wall of the mounting shaft 2 5. There is an auxiliary roller 9; the inner side wall of the second mounting groove is provided with a sliding groove 12, and a slider 11 is slidably connected in the sliding groove 12. The side of the slider 11 away from the sliding groove 12 is fixedly connected to the outer side wall of the movable block 10 to ensure the stability of the movable block 10 when sliding on the movable rod 16. The two sides of the mounting frame 1 and the second mounting frame 5 are fixedly connected with fixing plates. The upper surface of the fixing plate is provided with a fixing through hole. Through the fixing through hole, bolts and other fasteners can be used to firmly install the mounting frame 1 and the second mounting frame 5 on the dual frequency conversion micro wire drawing machine; the top of the mounting frame 1 is fixedly connected with a drive motor 1. The output end of the drive motor 1 is fixedly connected to one end of the adjusting screw 2 to drive the adjusting screw 2 to rotate.

[0017] In actual use, firstly, using bolts or other fasteners through the fixing holes on the fixing plate, securely install mounting bracket 1 and mounting bracket 2 5 onto the dual-frequency micro wire drawing machine. Start drive motor 1. The output end of drive motor 1 drives the adjusting screw 2 to rotate, causing adjusting block 3 to move up and down. The up and down movement of adjusting block 3 will cause mounting shaft 6 to move up and down. At the same time, the guide block moves axially along the guide groove, completing the adjustment of the distance between traction roller 7 and auxiliary roller 9. Adjust the distance to a suitable position according to actual production needs. Then, pass the wire between traction roller 7 and auxiliary roller 9. Start drive motor 2. The output end of drive motor 2 drives mounting shaft 6 to rotate, thereby driving traction roller 7 to rotate. With the help of auxiliary roller 9, the wire can be pulled.

[0018] Example 2: A mounting groove 3 is formed through the outer surface of mounting bracket 2 5. A guide groove is formed on the inner side wall of mounting groove 3. A guide block is slidably connected in the guide groove. An adjusting block 2 4 is fixedly connected to the side of the guide block away from the guide groove. A drive motor 2 is fixedly connected to the side of the adjusting block 2 4 away from mounting bracket 1 1. The output end of the drive motor 2 is fixedly connected to the end of mounting shaft 1 6 away from the adjusting block 3, for driving the mounting shaft 1 6 to rotate. An external thread 14 is formed on the outer surface of the end of the movable rod 16 near the bottom of the inner cavity of mounting groove 2. An adjusting knob 13 is threaded to the movable rod 16 through the external thread 14. Multiple rotating protrusions arranged in a ring array are fixedly connected to the outer surface of the adjusting knob 13 for easy gripping and rotation by the operator. A spring 15 is sleeved on the outer wall of the movable rod 16. One end of the spring 15 abuts against the upper surface of the adjusting knob 13, and the end of the spring 15 away from the adjusting knob 13 abuts against the bottom of the movable block 10, for cushioning the movable block 10.

[0019] In actual use, during the traction process, the auxiliary roller 9 can slide on the movable rod 16 according to the tension of the yarn. The spring 15 will buffer the movable block 10, reducing the impact force of the yarn on the roller surface of the auxiliary roller 9, and realizing flexible traction of the yarn. When it is necessary to traction yarn of different specifications, the operator can rotate the adjustment knob 13 by holding the rotating protrusion. Rotating the adjustment knob 13 can adjust the compression of the spring 15, thereby changing the buffering force of the auxiliary roller 9 on the yarn to adapt to the traction requirements of different yarns.

[0020] 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.
