Description

Technical Field

[0001] The utility model relates to a tension control device, in particular to a control device for the tension of continuous rolling of rods and wires, belonging to the technical field of continuous rolling of rods and wires. Background Art

[0002] Rods and wires are one of the important products in the steel industry. They are widely used in construction industries such as infrastructure and real estate, as well as in industrial fields such as machinery and metal products. In the production of rods and wires, they need to be continuously rolled. This is an efficient metal processing process that gradually rolls metal materials through multiple continuous rolling mill stands to make them thinner, longer and improve their mechanical properties.

[0003] In the continuous rolling process of bars and wires, it is very important to control the tension. The main reasons include ensuring product quality, maintaining production stability, improving production efficiency and preventing equipment damage. Appropriate tension can ensure that the bars and wires maintain uniform diameter and cross-sectional shape during the rolling process. However, in life, the equipment that controls the tension of bars and wires usually has a fixed tension. Since the diameter, material, temperature, speed and other parameters of the bars and wires will change during production, the fixed tension device will not be able to respond and adjust in time due to slight fluctuations and instability that may occur during the rolling process. This may lead to insufficient or excessive tension that is difficult to adapt to these changing conditions. When the tension is adjusted manually, the tension may be adjusted too high. Excessive tension will cause scratches, cracks and other defects on the surface of the bars and wires, affecting the appearance and performance of the product. At the same time, the internal structure of the bars and wires may be uneven, affecting the mechanical properties. Summary of the invention

[0027] The utility model provides a device for controlling the tension of continuous rolling of bars and wires.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 , including a base 1, four supporting legs 9 are fixed to the bottom surface of the base 1, and a non-slip pad is provided at the bottom end of each supporting leg 9, which can support the device and increase the stability of the device. An adjustment mechanism 2 and a reciprocating component 4 are provided on the base 1, and a buffer mechanism 3 is provided on the adjustment mechanism 2.

[0029] The adjustment mechanism 2 includes a fixed cylinder 201 fixed on the upper surface of the base 1 and a first rotating motor 202 fixed on the bottom surface of the base 1. A threaded rod 203 is fixed to the output end of the first rotating motor 202, and both ends of the threaded rod 203 are rotatably connected to the inner wall of the fixed cylinder 201. The outer surface of the threaded rod 203 is threadedly connected to a threaded block 204, and the outer surface of the threaded block 204 is in sliding contact with the inner wall of the fixed cylinder 201.

[0030] By starting the first rotating motor 202, the threaded rod 203 can be driven to rotate, and the rotation of the threaded rod 203 can drive the threaded block 204 to move up and down. The movement of the threaded block 204 can drive the adjustment rod 306 to move, thereby adjusting the tension of the rod wire.

[0031] Please refer to Figure 1 , Figure 3 and Figure 4 The buffer mechanism 3 includes a support plate 301 fixed on one side of the threaded block 204, a slide rod 302 is fixed on the upper surface of the support plate 301, a limit block 304 is fixed on the top of the slide rod 302, a slider 305 is slidably contacted on the outer surface of the slide rod 302, a telescopic spring 303 is sleeved on the outer surface of the slide rod 302, and the telescopic spring 303 is located between the slider 305 and the support plate 301, a fixing plate 307 is fixed on one side of the slider 305, and an adjusting rod 306 is fixed on the side of the fixing plate 307 away from the slider 305.

[0032] When the tension is too large, the rod wire will press the adjustment rod 306 downward, and the adjustment rod 306 will drive the slider 305 to move downward along the slide bar 302. The movement of the slider 305 will compress the telescopic spring 303, and the compression of the telescopic spring 303 can buffer the rod wire.

[0033] Please refer to Figure 1 The reciprocating assembly 4 includes two first support seats 401 fixed on the upper surface of the base 1, a second rotating motor 402 is fixed to one side of the first support seat 401, a bidirectional screw rod 403 is fixed to the output end of the second rotating motor 402, and both ends of the bidirectional screw rod 403 are rotatably connected to a side surface close to the two first support seats 401, and a driving block 404 is threadedly connected to the outer surface of the bidirectional screw rod 403.

[0034] The rotation of the bidirectional lead screw 403 can drive the driving block 404 to move back and forth along the bidirectional lead screw 403, so that the rod and wire can be evenly wound on the winding roller 7. Two limiting rods 405 are fixed on the upper surface of the driving block 404, and a limiting plate 406 is fixed on the top of the limiting rod 405 to limit the position of the rod and wire.

[0035] Please refer to Figure 1 Two second support seats 5 are fixed on the upper surface of the base 1, a third rotating motor 6 is fixed to one side of the second support seat 5, a winding roller 7 is fixed to the output end of the third rotating motor 6, and the two ends of the winding roller 7 are respectively rotatably connected to the side surfaces close to the two second support seats 5, so that the rods and wires can be wound, and the outer surfaces of the buffer mechanism 3 and the winding roller 7 are provided with rubber pads, which can prevent the surface of the rods and wires from being damaged.

[0036] A controller 8 is installed on the upper surface of the base 1 , and the first rotary motor 202 , the second rotary motor 402 and the third rotary motor 6 are all electrically connected to the controller 8 , so that their startup can be conveniently and accurately controlled.

[0037] When the utility model is in use: the rod and wire are passed through the two limit rods 405, then passed over the top of the adjusting rod 306 and finally wound on the winding roller 7, and then when the tension of the rod and wire needs to be adjusted, the first rotating motor 202 is controlled by the controller 8 to start, and starting the first rotating motor 202 can drive the threaded rod 203 to rotate, and the rotation of the threaded rod 203 can drive the threaded block 204 to move up and down, and the movement of the threaded block 204 can drive the adjusting rod 306 to move, and then the tension of the rod and wire can be adjusted, avoiding the small fluctuations and instability that may occur during the rolling process, resulting in insufficient or excessive tension, so that it can flexibly adapt to these changing working conditions and make adjustments.

[0038] When the tension is too great, the rod and wire will press the adjusting rod 306 downward, and the adjusting rod 306 will drive the slider 305 to move downward along the sliding rod 302. The movement of the slider 305 will compress the telescopic spring 303. The compression of the telescopic spring 303 can buffer the rod and wire, thereby avoiding scratches, cracks and other defects on the surface of the rod and wire due to excessive tension, thereby ensuring the appearance and performance of the product. At this time, the controller 8 controls the second rotary motor 402 and the third rotary motor 6 to start. The start of the second rotary motor 402 can rotate the bidirectional lead screw 403, so that the driving block 404 can reciprocate along the bidirectional lead screw 403, so that the rod and wire are evenly wound on the winding roller 7.
