Description

Technical Field

[0001] The utility model belongs to the technical field of cold-rolled stainless steel strip production equipment, and particularly relates to a deviation rectifying roller for cold-rolled stainless steel strip production. Background Art

[0002] The length of cold-rolled stainless steel strips varies slightly according to the size of each roll. The steel strips are generally supplied in rolls and have the advantages of high dimensional accuracy, good surface quality, easy processing, material saving, etc. The steel strips are divided into two categories: ordinary strips and high-quality strips according to the materials used; and are divided into hot-rolled strips and cold-rolled strips according to the processing methods.

[0003] During the processing and transportation of the existing conveyor belts, in order to prevent the steel strip from running off track, a deviation rectifying roller is often used to limit and rectify its position. However, the existing deviation rectifying roller has a low rectifying force, and when the deviation rectifying roller limits its position, it is easy to generate friction with the edge of the steel strip, resulting in wear of the deviation rectifying roller. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a deviation rectifying roller for cold-rolled stainless steel strip production, so as to solve the technical problems that the existing deviation rectifying roller has a low rectifying force and is easy to generate friction with the edge of the steel strip when limiting its position, resulting in wear of the deviation rectifying roller.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The deviation rectifying roller for cold-rolled stainless steel strip production includes a bracket. A fixed bracket is fixedly connected to the bottom end of the bracket. Symmetrically arranged guide rods are fixedly connected between the fixed brackets. A spring is sleeved on the guide rods. A first transmission frame and a second transmission frame are respectively slidably connected to the two guide rods. The two ends of the spring are respectively fixedly connected to the first transmission frame and the second transmission frame. Transmission plates are fixedly connected to the bottom ends of the first transmission frame and the second transmission frame. Symmetrically arranged round shafts are fixedly connected to the transmission plates. First transmission rods are rotatably connected to the round shafts fixedly connected to the first transmission frame. One ends of the first transmission rods far away from the round shafts are fixedly connected with rotating shafts. Second transmission rods are rotatably connected to the round shafts fixedly connected to the second transmission frame. The other ends of the second transmission rods far away from the round shafts are rotatably connected to the rotating shafts. A limit bracket is fixedly connected to the middle position of the fixed bracket. A limit groove is opened at the top end of the limit bracket. The two rotating shafts are slidably connected to the limit groove. Chutes are opened on the opposite sides of the first transmission frame and the second transmission frame. Sliders are slidably connected in the chutes. Mounting frames are fixedly connected to the opposite sides of the two sliders. Deviation rectifying rollers are rotatably connected to the mounting frames.

[0007] As a preferred scheme of the utility model, a plurality of conveying rollers are rotatably connected to the bracket, and the two deviation rectifying rollers and the two conveying rollers are correspondingly arranged.

[0008] As a preferred embodiment of the present utility model, the limiting bracket is of a T-shaped structure and is arranged corresponding to the rotating shaft.

[0009] As a preferred embodiment of the present utility model, one end of the first transmission rod close to the rotating shaft is of a concave structure, and one end of the second transmission rod close to the rotating shaft is of a convex structure.

[0010] As a preferred embodiment of the present utility model, the sliding groove is of a T-shaped structure, and the sliding block is of a T-shaped structure.

[0011] Compared with the prior art, the beneficial effects of the deviation rectifying roller for cold-rolled stainless steel strip production of the present utility model are as follows: when the steel strip deviates, the deviated steel strip extrudes the deviation rectifying roller, and the squeezed deviation rectifying roller pulls and stretches the spring through the transmission bracket. At the same time, it drives the transmission bracket on the other side to pull and stretch the spring through the first transmission rod and the second transmission rod, so that the spring undergoes twice the deformation and the contraction force is increased, and the deviation rectifying effect is better. And when the deviation rectifying roller wears, the sliding block arranged on the mounting frame can be taken out along the sliding groove for replacement, and the maintenance is relatively convenient.

[0020] See Figures 1-3 As shown, the deviation rectifying roller for cold-rolled stainless steel strip production in the embodiment of the present utility model includes a bracket 1. A fixed bracket 2 is fixedly connected to the bottom end of the bracket 1. Symmetrically arranged guide rods 3 are fixedly connected between the fixed brackets 2. A spring 4 is sleeved on one of the guide rods 3. A first transmission frame 5 and a second transmission frame 6 are respectively slidably connected to the two guide rods 3. The two ends of the spring 4 are respectively fixedly connected to the first transmission frame 5 and the second transmission frame 6. Transmission plates 7 are fixedly connected to the bottom ends of the first transmission frame 5 and the second transmission frame 6. Symmetrically arranged round shafts 8 are fixedly connected to the transmission plates 7. First transmission rods 9 are rotatably connected to the round shafts 8 fixedly connected to the first transmission frame 5. Rotating shafts 10 are fixedly connected to the ends of the first transmission rods 9 far from the round shafts 8. Second transmission rods 11 are rotatably connected to the round shafts 8 fixedly connected to the second transmission frame 6. The ends of the second transmission rods 11 far from the round shafts 8 are rotatably connected to the rotating shafts 10.

[0021] See Figure 3 As shown, a limit bracket 12 is fixedly connected to the middle position of the fixed bracket 2. A limit groove 13 is opened at the top end of the limit bracket 12. The two rotating shafts 10 are slidably connected to the limit groove 13. Sliding grooves 14 are opened on the opposite sides of the first transmission frame 5 and the second transmission frame 6. Sliders 15 are slidably connected in the sliding grooves 14. Mounting frames 16 are fixedly connected to the opposite sides of the two sliders 15. Deviation rectifying rollers 17 are rotatably connected to the mounting frames 16.

[0022] A number of conveying rollers 18 are rotatably connected to the bracket 1. Two deviation-correcting rollers 17 are correspondingly arranged between the two conveying rollers 18 to facilitate the correction of stainless steel. The limiting bracket 12 is designed in a T-shaped structure and is correspondingly arranged with the rotating shaft 10, so that the limiting bracket 12 can limit the rotating shaft 10, thereby limiting the first transmission plate 5 and the second transmission plate 6. One end of the first transmission rod 9 close to the rotating shaft 10 is designed in a concave structure, and one end of the second transmission rod 11 close to the rotating shaft 10 is designed in a convex structure to facilitate transmission. The sliding groove 14 is designed in a T-shaped structure, and the sliding block 15 is designed in a T-shaped structure to facilitate the sliding groove 14 to limit the sliding block 15.

[0023] When the stainless steel strip is offset and squeezes the deviation-correcting roller 17 arranged at the top of the second transmission frame 6 during the use of the embodiment of the present invention, the squeezed deviation-correcting roller 17 squeezes the second transmission frame 6 through the mounting frame 16 and the sliding block 15. The squeezed second transmission frame 6 pulls the spring 4. At the same time, the transmission plate 7 at the bottom of the second transmission frame 6 drives the round shaft 8 to move. The round shaft 8 pulls the rotating second transmission rod 11. The second transmission rod 11 pulled by the round shaft 8 pulls the rotating shaft 10. The pulled round shaft 8 moves towards each other along the limiting groove 13 opened in the limiting bracket 12. The moving rotating shaft 10 squeezes the first transmission rod 9. The squeezed first transmission rod 9 applies a squeezing force to the first transmission frame 5 through the round shaft 8. At this time, the first transmission frame 5 and the second transmission frame 6 move away from each other along the guide rod 3. The mutually separated first transmission frame 5 and second transmission frame 6 stretch the spring 4. The stretched spring 4 rebounds with a deformation force twice as large, and the deviation-correcting force is better. The rebounding spring 4 pulls the second transmission frame 6. The pulled second transmission frame 6 drives the deviation-correcting roller 17 through the mounting frame 16 to correct the stainless steel strip. When the deviation-correcting roller 17 is worn, the sliding block 15 arranged on the mounting frame 16 can be taken out along the sliding groove 14 for replacement.
