Description

Technical Field

[0001] This utility model relates to the field of tension adjustment technology, and in particular to a tension control device for a wire drawing machine. Background Technology

[0002] Wire drawing machines, also known as wire drawing machines or wire drawing machines, are widely used wire processing machinery in the industrial field. They can change the shape and properties of materials through tensile force and are suitable for processing a variety of materials. A search revealed that Chinese Patent CN214919270U discloses a tension adjustment device for a wire drawing machine, comprising a base, two fixed side plates, a feed roller, a connecting roller, and a discharge roller. Two tension rollers are positioned between the two fixed side plates. Each of the two fixed side plates has two first sliding grooves on its inner side, each containing a first slider. A fixed rod is also located within the first sliding groove, and two adjusting springs are positioned at the outer end of the fixed rod. By incorporating adjustable tension rollers, the device automatically adjusts the tension according to changes in pulling force, resulting in a more uniform pulling force applied to the material. This prevents the material from breaking due to excessive tension variations, leading to better stretching effect and improved stretching quality.

[0003] Although the tension adjustment device for wire drawing machines described above can use the elastic force of springs to buffer the material, the device cannot actively adjust the tension. It only relies on the passive extension and contraction of the adjusting spring to adapt to changes in tension. When processing materials of different materials and diameters, the required basic tension varies. The device can only passively respond to tension fluctuations and cannot adjust the material tension. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a tension control device for a wire drawing machine, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tension control device for a wire drawing machine includes a mounting frame. An mounting plate is rotatably connected to the inner wall of the mounting frame via a first bearing. An adjustment component is mounted on the mounting plate. A rotating component is mounted on the mounting frame. A first motor is fixedly connected to the back of the mounting plate. An extrusion roller and a conveying roller are positioned at the front of the mounting frame. The adjustment component includes a slide rod, a roller, and a second slider. The outer surface of the slide rod is fixedly connected to the inner wall of the mounting plate. The second slider is slidably sleeved on the outer surface of the slide rod. The rear end outer surface of the roller is rotatably connected to the front of the second slider via a first bearing seat.

[0006] Furthermore, the outer surface of the first motor output shaft rotates through the back of the mounting frame and extends to the front of the mounting frame via the second bearing. The front of the first motor output shaft is fixedly connected to the outer surface of the central shaft of the left conveyor roller, and the outer surface of the rear end of the right conveyor roller is rotatably connected to the front of the mounting frame via the second bearing seat. By setting the conveyor roller and the first motor, it is convenient to traction and convey materials.

[0007] Furthermore, a lead screw is provided inside the mounting frame. The outer surface of the top end of the lead screw rotates through the inner wall of the mounting frame and extends to the top of the mounting frame via a third bearing. A first slider is threaded onto the outer surface of the lead screw. The outer surface of the first slider is slidably connected to the inner wall of the mounting frame. The outer surface of the central shaft of the extrusion roller is rotatably connected to the front of the first slider via a third bearing seat. By setting up the lead screw, the first slider, and the extrusion roller, it is convenient to clamp and feed materials.

[0008] Furthermore, the adjustment assembly also includes a double-threaded screw, an adjusting block, and a spring. The outer surface of the left end of the double-threaded screw rotates through the inner wall of the mounting plate and extends to the outer side of the mounting plate via a fourth bearing. The rear end of the adjusting block is threaded onto the outer surface of the double-threaded screw, and the front end of the adjusting block is slidably fitted onto the outer surface of the slide bar. The outer surface of the second slider is slidably connected to the inner wall of the mounting plate. By setting the adjustment assembly, it is convenient to adjust the relative position of the roller and the mounting plate, thereby adjusting the positional relationship between the roller and the transmission roller, and thus adjusting the movement path of the material, thereby adjusting the tension of the material.

[0009] Furthermore, one end of the spring is fixedly connected to the outer surface of the adjusting block, and the other end of the spring is fixedly connected to the outer surface of the second slider, so as to prevent the material from breaking by utilizing the elastic force of the spring.

[0010] Furthermore, a bracket is fixedly connected to the outer surface of the second slider, and a limit roller is rotatably connected to the inner wall of the bracket through a fifth bearing seat. By setting the bracket and the limit roller, it is convenient to limit the material.

[0011] Furthermore, the rotating assembly includes a second motor, a gear, and a gear ring. The bottom surface of the second motor is fixedly connected to the top surface of the mounting bracket. The gear is fixedly sleeved on the outer surface of the output shaft of the second motor, and the gear ring is fixedly sleeved on the outer surface of the mounting plate. By setting the second motor, gear, and gear ring, it is convenient to drive the mounting plate to rotate and adjust the movement path of the material, thereby achieving the effect of adjusting the wire tension.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting a rotating component and changing the position of the mounting plate, the movement path of the wire can be adjusted, thereby changing the resistance of the wire during movement. This allows for automatic adjustment of the wire tension during the drawing process, matching the stretching requirements of different wire specifications and ensuring the drawing effect. By setting up adjustment components, the position between the two rollers and the two conveyor rollers can be easily adjusted, making the tension adjustment of the device more targeted and precise. This effectively avoids tension mismatch caused by differences in material properties, greatly expanding the applicability of the device. The elasticity of the springs facilitates buffering during the wire drawing process, preventing wire breakage. The rollers, supports, and limit rollers work together to limit the material, prevent the material from shifting or tangling during the drawing process, and ensure the stability of the transmission.
