TECHNICAL FIELD

[0001] The utility model relates to a tension levelling machine processing auxiliary device technical field especially relates to a tension levelling machine's roller balancing device. BACKGROUND

[0002] Tension levelling machine, also known as stretch bending straightening machine, is an important component of continuous casting machine casting equipment. Its main role is to send the dummy bar into the lower port of the crystallizer before casting, and to pull out the casting blank from the crystallizer and advance along the predetermined track after casting, while straightening the arc-shaped casting blank. When entering the breakout position, the breakout roller of the tension levelling machine is pressed down to separate the casting blank from the dummy bar. The tension levelling machine produces plastic extension of the strip through the combined action of stretching and bending to obtain straightening, and is widely used in straightening process of plate and strip. Since the tension levelling machine needs to bear large tension and bending force during work, the parallelism and position stability between rollers have important influence on straightening effect and equipment life.

Detailed Implementation

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] This utility model provides a roller balancing device for a tension leveling machine, including a base 1, with pads 101 evenly distributed on the bottom of the base 1. A bracket 2 is mounted on the base 1, and a pressure roller 201 is rotatably connected to the bracket 2. A first motor 202 is mounted on the right end of the bracket 2, and the output end of the first motor 202 is connected to the pressure roller 201. A frame 3 is slidably arranged above the bracket 2, and the frame 3 is located in the same vertical direction as the bracket 2. A roller shaft 301 is rotatably connected to the frame 3, and a second motor 302 is mounted on the right end of the frame 3. The output end of the second motor 302 is connected to the roller shaft 301. The frame 3 is connected, and a material 5 to be straightened is placed between the pressure roller 201 and the roller shaft 301. Connecting plates 303 are installed on both sides of the frame 3. A hydraulic cylinder 304 is installed on the base 1 below the connecting plate 303 on the left side. The output end of the hydraulic cylinder 304 is connected to the bottom of the connecting plate 303. A limiting frame 4 is installed on the right side of the connecting plate 303 on the right side. A sliding groove 401 is provided on the limiting frame 4. A spherical protrusion 402 is installed on the right end of the connecting plate 303 on the right side. The spherical protrusion 402 and the sliding groove 401 fit together to ensure that the connecting plate 303 on the right side slides in the limiting frame 4 with structural protection.

[0019] In actual use, the roller balancing device of the tension leveler adaptively adjusts the height of the frame 3 relative to the support 2 according to the thickness of the material to be straightened. The hydraulic cylinder 304 drives the output end to move the left connecting plate 303, assisting the frame 3 in vertical displacement above the support 2. During this vertical displacement, the frame 3 slides in the groove 401 of the limiting frame 4 via the spherical protrusion 402 of the right connecting plate 303. Simultaneously, a guide post 404 is installed below the right connecting plate 303, cooperating with the guide sleeve 403 to ensure support and assistance for the frame 3 during its vertical sliding. After the frame 3 is adjusted to its relative position, the hydraulic cylinder 304 is in a pressure-holding state, restricting the longitudinal displacement of the frame 3. The structure provides structural support for the straightening of the material to be straightened 5. Then, the first motor 202 and the second motor 302 drive the corresponding pressure rollers 201 and roller shafts 301 to rotate, ensuring that the straightening of the material to be straightened 5 can be carried out. By installing an adjustable frame 3 above the support 2, the height of the frame 3 relative to the support 2 can be adjusted according to the thickness of the material to be straightened 5. Compared with the conventional roller balancing device that uses fastener threaded connection, the technical solution adopted by this utility model reduces the labor intensity of the workers. The frame 3 can be flexibly adjusted above the support 2, with high structural flexibility, compact overall structure, and easy installation and maintenance by the workers.

[0020] Example 1

[0021] like Figs. 1-2 As shown, a guide sleeve 403 is installed on the base 1 below the connecting plate 303 on the right side. A guide post 404 is slidably connected to the guide sleeve 403. The top of the guide post 404 is connected to the bottom of the connecting plate 303 on the right side. An oil inlet 405 is installed on the side wall of the guide sleeve 403. An anti-detachment block 406 is installed at the bottom of the guide post 404. The diameter of the anti-detachment block 406 is the same as the inner diameter of the guide sleeve 403 and larger than the diameter of the guide post 404.

[0022] The effect achieved by the entire embodiment 1 is that, in use, the diameter of the anti-detachment block 406 is the same as the inner wall diameter of the guide sleeve 403 and larger than the diameter of the guide post 404, which limits the sliding stroke of the guide post 404 in the guide sleeve 403, and at the same time provides structural support for the right connecting plate 303 when sliding up and down.

[0023] Working principle: The height of the frame relative to the support is adaptively adjusted according to the thickness of the material to be straightened. The hydraulic cylinder drives the output end to move the left connecting plate to assist the frame in moving up and down above the support. When the frame moves up and down, the spherical protrusion of the right connecting plate slides in the groove in the limiting frame. At the same time, the guide post and guide sleeve set below the right connecting plate cooperate with each other to ensure that the frame has a supporting function when sliding up and down. After the frame is adjusted to the relative position, the hydraulic cylinder is in the pressure holding state to restrict the longitudinal displacement of the frame, providing structural protection for the straightening of the material to be straightened. Then, the first motor and the second motor drive the corresponding pressure rollers and roller shafts to rotate, ensuring that the straightening of the material to be straightened is carried out.
