However, the traditional wire drawing machine has significant deficiencies in controlling the tension of the metal wire before it passes through the wire drawing die. Due to the influence of various factors such as equipment design, process parameter settings, material quality and operating technology, the tension of the metal wire before entering the die is often difficult to maintain stable, resulting in large tension fluctuations during the wire drawing process, which in turn affects the diameter consistency, surface finish and overall performance of the welding wire.

DETAILED DESCRIPTION

[0018] In order to better understand the present invention, Figures 1 to 4 To explain the implementation of the present utility model in detail.

[0019] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0020] See also Figures 1 to 4The utility model is a tension-controllable wire drawing machine, comprising a frame 1 in the prior art, on which an unwinding wheel frame 2, a guide assembly, a wire drawing assembly 3 and a driving winding wheel 4 are sequentially arranged along the forward direction of the wire drawing, wherein the unwinding wheel frame 2 is rotatably arranged on the frame 1, and is used for placing an I-shaped wheel of the metal wire, the guide assembly is used for guiding the metal wire on the I-shaped wheel, the wire drawing assembly 3 is used for wire drawing forming, and the driving winding wheel 4 is rotated by a motor to wind up the drawn metal wire.

[0021] On the basis of the above-mentioned prior art, the frame 1 is additionally provided with a tension control component 5 between the guide component and the wire drawing component 3, and the tension control component 5 includes a fixed plate 6 mounted on the frame 1, and a vertical slide rail 7 is arranged on the fixed plate 6, and a slider 8 is arranged in the vertical slide rail 7, and a driving mechanism for driving the slider 8 to slide up and down in the vertical slide rail 7 is arranged on the fixed plate 6, and a wheel seat 9 is arranged on the slider 8, and a pressure sensor 10 is arranged between the wheel seat 9 and the slider 8, and a tension pressure wheel 11 is arranged on the wheel seat 9.

[0022] The tension pressure wheel 11 of the tension control assembly 5 is always pressed on the metal wire, and the pressure is fed back through the pressure sensor 10 through the contact between the tension pressure wheel 11 and the metal wire. The position of the slider 8 in the vertical slide rail 7 is adjusted by the driving mechanism. The contact pressure between the tension pressure wheel 11 and the metal wire is precisely controlled to keep the contact pressure between the tension pressure wheel 11 and the metal wire within a range suitable for wire drawing, thereby achieving precise regulation of the tension. Due to the real-time monitoring of the pressure sensor 10, real-time feedback and rapid response through the driving mechanism can be provided to adjust the tension value to meet different processing requirements. This design principle is based on the theory of mechanical balance and feedback control. The tension of the metal wire is changed by adjusting the pressure of the tension pressure wheel 11 on the metal wire, thereby meeting the tension control requirements under different processing requirements.

[0023] In order to more accurately control the position of the slider 8 and thus fine-tune the tension, Figure 2 and Figure 3 As shown in the figure, the present invention adopts a driving mechanism composed of a first lead screw 12 and a second lead screw 13 with opposite rotation directions. The two lead screws rotate synchronously through mutually meshing gears 15, but in opposite directions, thereby driving the slider 8 to move up and down in the vertical slide rail 7. The lead screw motor 16 is used as a power source and is connected to the first lead screw 12 or the second lead screw 13 to achieve precise control of the driving mechanism. This dual lead screw transmission design not only improves the stability and response speed of the system, but also enables the slider 8 to respond to the pressure fluctuation detected by the pressure sensor 10 in a timely manner and adjust the position up and down in a timely manner.

[0024] In order to further improve the transmission efficiency and stability of the driving mechanism, the gears 15 are all helical gears as transmission elements. The meshing of helical gears has a higher transmission ratio and better self-locking performance, which can effectively prevent transmission failure caused by load changes. At the same time, a guide column 17 is inserted into the slide groove, and a sleeve 18 matched with the guide column 17 is provided on the slider 8, which further enhances the stability and accuracy of the slider 8 during movement.

[0025] like Figure 1 As shown in the figure, the guide assembly is composed of a guide main wheel frame 19 and a guide sub-wheel frame 20, which work together to guide the metal wire to maintain a stable path and posture before entering the tension control assembly 5.

[0026] In order to maintain the cleanliness of the surface of the metal wire, a group of cleaning sleeves 21 are arranged between the guide sub-wheel frame 20 and the tension control assembly 5, and between the wire drawing assembly 3 and the driving winding wheel 4. These cleaning sleeves 21 adopt the existing technology, both ends of the cleaning sleeves 21 are open and a circle of oil-absorbing sponges are arranged inside, which can effectively remove impurities and lubricant residues on the surface of the metal wire, ensuring the smooth progress of the wire drawing process and the quality of the final product.

[0027] In order to meet the processing requirements of metal wires of different specifications and shapes, the wire drawing assembly 3 adopts a detachable wire drawing die design. This design allows users to easily replace the die according to production requirements, improving the flexibility and versatility of the equipment. At the same time, the forming frame serves as an installation platform for the wire drawing die, providing a stable support and precise positioning for the die.
