DETAILED DESCRIPTION
[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0016] like Figure 1 As shown, the titanium alloy wire is sequentially passed through several sets of annealing furnaces 11 for online annealing at a temperature of 775±20℃ and a speed of 2~3m / min, and is water-cooled; the tension of the material is adjusted and controlled by a self-designed tension swing winding and unwinding device 10.
[0017] like Figure 1 As shown, the tension swing winding and unwinding device 10 includes a winding machine 12 located at the front of the annealing furnace 11. A front guide wheel shaft is provided at the front end of the winding machine 12, and a front guide wheel 13 is mounted on the front guide wheel shaft. A pair of guide wheels 14 are provided at the front end of the front guide wheel 13. The device also includes an unwinding machine 18 located at the rear of the annealing furnace, with a rear guide wheel 15 at its front end. A fixed rotating shaft 171 and a lever 17 are provided between the rear guide wheel 15 and the unwinding machine 18. The lever 17 is movably connected to the annealing furnace 11 via the fixed rotating shaft 171 and can swing around the fixed rotating shaft 171. A lever guide wheel shaft 162 is provided at one end of the lever 17. The lever guide wheel 16 is provided on the lever guide wheel shaft 162, and the other end of the lever 17 is provided with a counterweight 19. The counterweight 19 is movably mounted on the lever 17, and a fastening screw 191 is provided on the counterweight 19. This design allows for easy adjustment and convenient fastening of the counterweight 19.
[0018] Furthermore, such as Figure 2 As shown, in order to achieve online continuous measurement and automatic adjustment of tension, a guide groove 172 is provided on the lever 17 along its length. A tension indicator scale 173 is provided on one side of the lever 17 with the guide groove 172. The lever guide wheel 16 is mounted on the slider 161 through a wheel axle. The slider 161 is slidably mounted in the guide groove 172 of the lever 17 and can be locked on the lever 17 with screws. This design allows for a direct display of the position of the adjustment lever guide wheel 16, enabling online continuous automatic adjustment of tension. In addition, the lever 17 corresponding to the counterweight 19 is also provided with a tension indicator scale 173, which allows for a direct display of the screw-in depth of the fastening screw 191. Adjusting the distance of the counterweight 19 to the center of the fixed rotating shaft facilitates the adjustment of the counterweight and achieves tension adjustment.

[0020] The use method of the device is as follows: 1. firstly, the device is installed at both ends of the annealing furnace 11 before use; 2. the position of the counterweight 19 on the lever 17 is initially adjusted by loosening the tight nail screw 191, so that the lever 17 is in a balanced position; 3. the titanium alloy wire is wound around the front guide wheel 13, the lever guide wheel 16 and the rear guide wheel 15; 4. the winding machine 12 is started, and the tension of the titanium alloy wire is measured by using a hand-held tension meter according to the production process requirements of the titanium alloy wire, so that the position of the counterweight 19 on the lever 17 is finely adjusted, and the lever 17 is in a balanced position; 5. after the position of the counterweight 19 on the lever 17 is finely adjusted, and the lever 17 is in a balanced position, the automatic adjustment of the tension in the production process of the titanium alloy wire is realized by using the simple lever principle.
[0021] The above only describes the preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
