Description

Technical Field

[0001] This utility model relates to the field of clamping technology for tungsten wire drawing machines, specifically a clamping device for a tungsten wire drawing machine. Background Technology

[0002] Tungsten wire drawing is the process of turning tungsten bars into fine wires through forging, drawing and other processes. It is mainly used to manufacture light bulb filaments and high-speed cutting alloy steel. During the drawing process, the tungsten wire needs to undergo multiple drawing processes, and the diameter gradually decreases. At the same time, it is necessary to maintain the surface smoothness and strength. This process has extremely high requirements for the precision and stability of the clamping device. Any slight slippage or deviation may cause the tungsten wire to break or become dimensionally unqualified, which is why the clamping device of the tungsten wire drawing machine is needed.

[0003] According to the patent application disclosed on the Internet (CN 217990434 U), a clamping device for a tungsten wire drawing machine is described as follows: "A clamping device for a tungsten wire drawing machine includes a device body, a supporting foot at the bottom of the device body, a worktable at the top of the device body, an unwinding device on one side of the worktable, a winding device on the other side of the worktable, a wire guide device on one side of the unwinding device, a constant speed roller in the inner groove of the wire guide device, a constant speed motor on one side of the constant speed roller, a wire drawing die at the bottom of the constant speed roller, a servo motor on one side of the winding device, a template guide wheel on one side of the top of the winding device, and a control panel on one side of the device body."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, both the drawing die and the constant-speed roller can be moved and adjusted within the movable groove via a movable rod, and the position is quickly fixed by a locking block, which is convenient for handling drawing dies of different sizes. The drawing die is rotatably connected to the movable rod via an adjusting block, and the adjusting block and the fixing block can adjust the drawing die to meet different usage conditions. However, in actual use, when adjusting the position of the constant-speed roller, the corresponding locking block needs to be manually removed and then moved to the appropriate position. This increases the tediousness of the adjustment process for the operator and makes it inconvenient to adjust the distance between the upper and lower constant-speed rollers simultaneously, thus increasing the time before production preparation. Therefore, it is necessary to improve the clamping device of the tungsten wire drawing machine. Utility Model Content

[0035] Based on the existing technology's need to fix the coil material, please refer to... Figure 5 Furthermore, in conjunction with Embodiment 1, it is further found that the fixed winding mechanism 2 includes a support plate 21, which is fixedly connected to the top of the connecting seat 1.

[0037] In actual operation, when the device is in use, the control method of this utility model is controlled by manually starting and stopping the switch.

[0038] First, the corresponding roll of material is placed on the fixed winding mechanism 2. The roll is then placed on the left placement rod 24, and the threaded sleeve 25 is reset, thus fixing the roll between the rotating plate 23 and the threaded sleeve 25. Simultaneously, the right placement rod 24 holds the corresponding winding drum. This process is repeated to fix the winding drums at both ends. Meanwhile, according to the required tungsten wire tensioning distance for different production types, the fastening quick-release mechanism 5 is used. The servo motor 512 is activated, driving the rotating rod 513 to rotate. During the rotation of the rotating rod 513, the two end pull rods 514 and 515 are simultaneously driven. The movement of lever 2 517 causes the corresponding sliding plates 1 515 and 2 518 to move synchronously during the movement of lever 1 514 and lever 2 517. This, in turn, causes the constant speed rollers 1 516 and 2 519 to move synchronously, allowing the distance between the two constant speed rollers 1 516 and 2 519 on the upper and lower sides to be adjusted synchronously as needed. Then, the tungsten wire is passed through the bottom of guide roller 1 4 and the top of constant speed roller 1 516, and simultaneously through the middle of drawing die 525, and then through the bottom of constant speed roller 2 519. One end of the wire is then fixed to the right take-up roller by passing through guide roller 2 6. The unwinding and take-up speeds are controlled by the cooperation of the two servo motors 2 22.
