Description

Technical Field

[0001] This utility model relates to the technical field of wire drawing machines, specifically a wire drawing machine that automatically adjusts the winding tension. Background Technology

[0002] A metal wire drawing machine is a mechanical device used for processing metal wires. It processes metal materials into wires of different diameters and shapes through a drawing process. The working principle of a metal wire drawing machine is to apply tension to the metal wire using a drawing die, forcing the wire through the die hole, thereby reducing the wire diameter and increasing its length. During the drawing process, the wire usually needs to be cooled and lubricated to reduce its temperature and friction, ensuring the surface quality and drawing effect of the wire. The processed metal wire usually needs to be wound up and stored. The winding mechanism usually needs to be used in conjunction with a tension adjustment mechanism to prevent the metal wire from breaking during winding.

[0003] The tension adjustment mechanisms currently used in traditional wire drawing equipment rely on mechanical tension control, such as friction wheels or spring structures. These mechanisms are difficult to respond in real time to tension fluctuations caused by changes in the resistance of the metal wire deformation, die wear, or speed changes. This can easily lead to wire breakage or uneven wire diameter. Studies have shown that the wire breakage rate of traditional equipment can reach 5%-8%, which seriously affects continuous production efficiency and material utilization. Therefore, there are drawbacks in its use. Utility Model Content

This can easily lead to wire breakage or uneven wire diameter. Studies have shown that the wire breakage rate of traditional equipment can reach 5%-8%, which seriously affects continuous production efficiency and material utilization. Therefore, it has drawbacks in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0016] 1. This utility model includes a first damping adjustment wheel, a second damping adjustment wheel, and a detection wheel. In use, a tension meter connected to the detection wheel detects the tension of the metal wire in real time. When tension fluctuates, an adjustment motor, in conjunction with a meshing disc, drives an adjustment rod to rotate, which in turn drives the second damping adjustment wheel to actively adjust the tension of the metal wire. Simultaneously, a first damping adjustment wheel connected to a spring is provided. Through the deformation of the spring, the tension of the metal wire is passively and automatically adjusted, compensating for the delay of active adjustment. By combining active and passive adjustments, the accuracy of adjustment is improved, thereby enhancing product quality.

[0017] 2. This utility model includes a tray located below the take-up roller. Two sliding rollers are positioned on the top of the tray. As the diameter of the metal wire coil wound by the take-up roller increases, the sliding rollers rotate synchronously with the metal wire coil when the outer side of the wire coil contacts the sliding rollers. At this point, the device is closed. Simultaneously, the sliding rollers, together with the tray, provide bottom support for the wire coil. By pulling the tray outward, the wire coil can be disengaged from the take-up roller. Furthermore, the two trays prevent the wire coil from rolling, thus improving production safety.

[0028] In this embodiment, the metal wire processed by the wire drawing machine body 1 is discharged through the wire outlet 24.

[0029] More specifically, the tension of the metal wire is detected in real time by using tension gauge 15 in conjunction with detection wheel 17.

[0030] In this embodiment, a damping wheel 4 is provided above the winding roller 3, and a first fixed pulley 5 is provided above the damping wheel 4. Both the damping wheel 4 and the first fixed pulley 5 are installed on one side of the tension adjustment chamber 2.

[0031] In this embodiment, the take-up roller 3 is connected to a power device, and the take-up roller 3 rotates actively and continuously during use.

[0032] More specifically, the function of the damping wheel 4 is to generate controllable resistance to suppress or eliminate tension fluctuations, vibrations and inertial impacts in the system, thereby achieving stable tension control and ensuring the consistency and safety of the material during the winding process.

[0033] In this embodiment, the first guide rail 6 and the first slider 7 are connected by a sliding connection, and the first slider 7, the spring 8 and the first damping adjustment wheel 9 form a telescopic structure.

[0034] In this embodiment, the tension of the metal wire will give the first damping adjustment wheel 9 a lateral pulling force, which is offset by the deformation of the spring 8, thereby automatically adjusting the tension of the metal wire.

[0035] More specifically, the first damping adjustment wheel 9 is fixedly connected to the first slider 7, and they can slide left and right together along the first guide rail 6.

[0036] In this embodiment, the mounting bracket 10 and the adjusting rod 11 are connected by a rotatable connection, and an adjusting motor 12 is installed on the rear side of the mounting bracket 10. At the same time, the output shaft of the adjusting motor 12 is connected to the meshing disc 13. The meshing disc 13, the adjusting rod 11, and the second damping adjusting wheel 14 form a rotating structure.

[0037] In this embodiment, the tension meter 15 controls the start and stop of the regulating motor 12.

[0038] More specifically, by adjusting the motor 12 to drive the meshing disc 13 to rotate, the second damping adjustment wheel 14 is driven to rotate synchronously, thereby precisely adjusting the tension of the metal wire.

[0039] In this embodiment, the second slider 22 and the second guide rail 23 are connected by a sliding connection, and the second guide rail 23, the tray 19 and the roller 20 form a sliding structure.

[0040] In this embodiment, the roller 20 always remains in contact with the ground, and the upper front end of the tray 19 is provided with a handle.

[0041] More specifically, by pulling the handle, the tray 19 moves back and forth, and the second slider 22 slides along the corresponding second guide rail 23 simultaneously.

[0042] In this embodiment, the vertical axis of the tray 19 and the axis of the take-up roller 3 are on the same vertical plane, and two sliding rollers 21 are installed on the top of the tray 19, and the two sliding rollers 21 are symmetrically distributed about the vertical axis of the tray 19.

[0043] In this embodiment, when the diameter of the metal wire coil wound by the take-up roller 3 reaches its maximum, the outer side of the metal wire coil will come into contact with the two sliding rollers 21.

[0044] More specifically, the bottom of the metal wire coil is supported by two take-up rollers 3 in conjunction with the tray 19.

[0045] The working principle of this utility model is as follows: In use, the metal wire passes sequentially from top to bottom around the first fixed pulley 5, the first damping adjusting wheel 9, the damping wheel 4, the second damping adjusting wheel 14, the second fixed pulley 18, and the detection wheel 17. Finally, the end of the metal wire to be wound is fixed on the winding roller 3. Then, the winding roller 3 is started, and the metal wire is pulled to start winding. During this process, when the tension of the metal wire changes, the spring 8 will first follow the change in the tension of the metal wire and actively contract and extend, thereby driving the first damping adjusting wheel 9 and the first slider 7 to slide together along the first guide rail 6. At the same time, when the tension exceeds the set threshold of the tension meter 15, the tension meter 15 starts the adjusting motor 12. The adjusting motor 12 drives the meshing disk 13 to rotate, which in turn, together with the adjusting rod 11, drives the second damping adjusting wheel 14 to start rotating along the axis of the meshing disk 13, thereby actively adjusting the tension of the metal wire.
