Description

Technical Field

[0001] The utility model belongs to the field of metal wire production equipment, in particular to a tension regulating device for a wire-releasing device of a wire drawing machine with high adaptability. Background Art

[0002] With the advancement of science and technology, metal wire is increasingly used in social production due to its high strength and light weight. In different industries, especially in the precision instrument production industry, people have higher and higher requirements for metal wire. Therefore, metal wire production companies have been committed to optimizing each process in the production of metal wire to further improve the final quality of the metal wire and the stability and uniformity of the overall quality. During the unwinding process before drawing, the metal wire is usually adjusted through a tension device. However, the existing tension device is usually relatively fixed and cannot flexibly adapt to the unwinding of I-shaped wheels with different widths and different winding diameters. During the unwinding process, it is also unable to flexibly respond to changes in angles, resulting in a certain tension fluctuation of the metal wire after unwinding. For this reason, people hope to improve this to better protect the metal wire and make the quality of the finished product more stable. Utility Model Content

[0029] Usage process:

[0030] Before paying out the wire, by adjusting the left and right position of the horizontal slide bar on the base, it can adapt to the wire payout of I-shaped wheels with different widths;

[0031] By adjusting the up and down position of the vertical moving rod on the horizontal sliding rod, it is possible to adapt to the I-shaped wheel pay-off of different winding diameters. Specifically, when it is necessary to adjust the up and down position of the vertical moving rod on the horizontal sliding rod, the rotating locking adjusting rod will change the long side of the elliptical adjusting block from horizontal to vertical, and the expanding moving rod will be pulled back from the side wall of the slide groove under the action of the return spring. Thereafter, the position of the vertical moving rod can be adjusted up and down. After the adjustment is completed, the rotating locking adjusting rod will change the long side of the elliptical adjusting block from vertical to horizontal, and the expanding moving rod will be pushed out again to closely cooperate with the side wall of the slide groove, thereby locking the slider into position in the slide groove. As a result, the position of the vertical moving rod is fixed.

[0032] By adjusting the angle of the rocker arm relative to the vertical moving rod, the initial angle at which the wire cuts into the tension wheel can be adjusted. Specifically, first loosen the locking nut, locate the position of the rocker arm, and then tighten the locking nut to fix the rocker arm.

[0033] During the pay-off process, the tension wheel can rotate flexibly with the pay-off angle and tension changes due to the existence of the rotating shaft, which can greatly buffer and release the tension change caused by the angle change when the I-spool wheel pays off the wire, and can better protect the silk thread from being damaged while adjusting the tension.

[0034] The utility model discloses a tension adjustment device for a wire drawing machine pay-off device with high adaptability, and has an ingenious structure. Before pay-off, the position of the tension wheel can be adjusted up and down, left and right, and the angle at which the metal wire cuts into the tension wheel can be adjusted as needed, thereby being adaptable to I-shaped wheel pay-offs of different widths and different winding diameters, and having strong adaptability. Moreover, the tension wheel can be flexibly rotated during the pay-off process as the pay-off angle and tension change, thereby being able to greatly buffer and release the tension change caused by the angle change when the I-shaped wheel pays off, and can better protect the wire from being damaged while adjusting the tension. It has good flexibility, strong practicality, and is worthy of promotion.

[0035] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
