Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically a rolling mill positioning and adjustment mechanism. Background Technology

[0002] Rolls are the main working components and tools on a rolling mill that cause continuous plastic deformation of metal. A roll mainly consists of three parts: the roll body, the roll neck, and the shaft end. The roll body is the middle part of the roll that actually participates in the rolling of metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in a bearing and transmits the rolling force to the mill stand through the bearing housing and the pressing device. The drive end shaft end is connected to a gear housing via a connecting shaft, transmitting the rotational torque of the motor to the roll. Rolls can be arranged in two-roll, three-roll, four-roll, or multi-roll configurations within the rolling mill stand.

[0003] In the prior art, such as Chinese patent CN217121277U, a rapid axial adjustment device for a rolling mill is disclosed, including a base and a rolling mill body. The rolling mill body is located above the base, and adjustment structures are provided on both sides of the rolling mill body. The adjustment structure includes: a pair of brackets, a pair of bearings, a first support plate, a second support plate, a push-pull electromagnet, a fixing sleeve, a spring, and a telescopic top. The pair of brackets are installed on the upper wall of the base, and the left and right walls of the pair of brackets have through holes. The pair of bearings are installed on the through holes on the left and right walls of the pair of brackets. The two ends of the rolling mill body are installed on the pair of bearings, and the rolling mill body is located above the base.

[0004] However, in the existing technology, when existing rolling mills roll steel of different thicknesses, the rolling mills do not have an adjustment function, which causes the steel to be subjected to different extrusion pressures. This makes it impossible to ensure that the same extrusion pressure is applied to different steels, thus reducing processing efficiency. Utility Model Content

[0018] The first bevel gear 5 is movably sleeved on both ends of the outer side of the drive rod 4. The first bevel gear 5 has a limiting groove 19. A limiting strip 18 is movably inserted through the inner cavity of the limiting groove 19. The limiting strip 18 is fixedly connected to the rear side wall of the drive rod 4. A horizontal plate 6 is fixedly connected to the side wall of the first bevel gear 5. A wing screw 7 is movably inserted into the top of the horizontal plate 6. Four positioning holes 8 are opened at the top of the drive rod 4. The bottom end of the wing screw 7 is threaded into the inner cavity of the adjacent positioning hole 8. An arc groove is opened at the bottom of the horizontal plate 6. The inner wall of the arc groove fits against the outer side wall of the drive rod 4.

[0019] In the above embodiment, during use, the wing screw 7 is unscrewed to release the fixation between the horizontal plate 6 and the first bevel gear 5. Then, the first bevel gear 5 is moved away from the second bevel gear 16. Through the setting of the limiting groove 19 and the limiting strip 18, the first bevel gear 5 moves within the limited trajectory. At this time, the horizontal plate 6 corresponds to the adjacent positioning hole 8. Then, the wing screw 7 is tightened to fix the first bevel gear 5. At this time, the first bevel gear 5 does not mesh with the second bevel gear 16. Then, the motor 9 is started by the external power supply. The motor 9 drives the fixed roller 3 to rotate through the drive rod 4. The workpiece to be processed is placed in the gap between the two fixed rollers 3 and the movable roller 12. The metal material is processed by the fixed rollers 3 and the movable roller 12, thereby achieving the effect of replacing the existing single roller for extruding and transporting metal materials, which can improve the conveying efficiency of metal materials. Example 2

[0020] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7A rotating shaft is fixedly installed through the inner cavity of the movable roller 12. Movable blocks 13 are rotatably connected to both ends of the rotating shaft. Slide grooves 17 are opened on the left and right sides of the fixed frame 2. The movable blocks 13 are slidably connected to the inner cavity of the slide grooves 17. The movable blocks 13 and the slide grooves 17 are matched with each other. A screw hole is opened on the movable block 13. A lead screw 14 is installed through the inner cavity of the screw hole. Two fixed plates 15 are fixedly connected to the left and right side walls of the fixed frame 2. The fixed plates 15 are close to the two ends of the lead screw 14. The lead screw 14 is rotatably connected to the fixed plates 15. The lead screw 14 is threadedly connected to the screw hole. The threads of the two lead screws 14 are opposite in direction. A second bevel gear 16 is fixedly sleeved on the top of the lead screw 14. The second bevel gear 16 meshes with the first bevel gear 5.

[0021] In the above embodiment, when it is necessary to adjust the distance between the fixed roller 3 and the movable roller 12, first stop the motor 9, unscrew the wing screw 7, and release the fixation between the horizontal plate 6 and the first bevel gear 5. Then move the first bevel gear 5 towards the second bevel gear 16. Through the setting of the limiting groove 19 and the limiting strip 18, the first bevel gear 5 moves within the limited trajectory until the first bevel gear 5 and the second bevel gear 16 mesh with each other. At this time, the horizontal plate 6 corresponds to the adjacent positioning hole 8. Then tighten the wing screw 7 to fix the first bevel gear 5. At this time, the first bevel gear 5 and the second bevel gear 16 mesh with each other. Then start the motor through the external power supply. 9. The motor 9 drives the drive rod 4 to rotate forward or backward. The drive rod 4 drives the first bevel gear 5 to rotate. The first bevel gear 5 drives the lead screw 14 to rotate through the second bevel gear 16. The two lead screws 14 rotate in opposite directions. Since the threads of the two lead screws 14 are opposite, when the two lead screws 14 rotate, they drive the two movable blocks 13 to move in the same direction. The movable blocks 13 drive the movable roller 12 to move. The movable blocks 13 move in the inner cavity of the slide groove 17, thereby adjusting the distance between the movable roller 12 and the fixed roller 3. This allows the device to be used for processing workpieces of different thicknesses, improving the flexibility of the device and increasing the processing quality and efficiency.

[0022] Working principle: This utility model discloses a roller positioning and adjustment mechanism. By unscrewing the wing screw 7, the horizontal plate 6 and the first bevel gear 5 are released from their fixation. Then, the first bevel gear 5 is moved away from the second bevel gear 16. Through the setting of the limiting groove 19 and the limiting strip 18, the first bevel gear 5 moves within a limited trajectory. At this time, the horizontal plate 6 corresponds to the adjacent positioning hole 8. Then, the wing screw 7 is tightened to fix the first bevel gear 5. At this time, the first bevel gear 5 does not mesh with the second bevel gear 16. Then, the motor 9 is started by an external power supply. The motor 9 drives the fixed roller 3 to rotate through the drive rod 4. The workpiece to be processed is placed in the gap between the two fixed rollers 3 and the movable roller 12. The fixed rollers 3 and the movable roller 12 process the metal material, thereby achieving the effect of replacing the existing single roller for extruding and transporting metal materials, and improving the conveying efficiency of metal materials.

[0023] When it is necessary to adjust the distance between the fixed roller 3 and the movable roller 12, first stop the motor 9, unscrew the wing screw 7, and release the fixation between the horizontal plate 6 and the first bevel gear 5. Then move the first bevel gear 5 towards the second bevel gear 16. Through the setting of the limiting groove 19 and the limiting strip 18, the first bevel gear 5 moves within the limited trajectory until the first bevel gear 5 and the second bevel gear 16 mesh with each other. At this time, the horizontal plate 6 corresponds to the adjacent positioning hole 8. Then tighten the wing screw 7 to fix the first bevel gear 5. At this time, the first bevel gear 5 and the second bevel gear 16 mesh with each other. Then start the motor 9 through the external power supply. 9 drives the drive rod 4 to rotate forward or backward. The drive rod 4 drives the first bevel gear 5 to rotate. The first bevel gear 5 drives the lead screw 14 to rotate through the second bevel gear 16. The two lead screws 14 rotate in opposite directions. Since the threads of the two lead screws 14 are opposite, when the two lead screws 14 rotate, they drive the two movable blocks 13 to move in the same direction. The movable blocks 13 drive the movable roller 12 to move. The movable blocks 13 move in the inner cavity of the slide groove 17, thereby adjusting the distance between the movable roller 12 and the fixed roller 3. This allows the device to be used for processing workpieces of different thicknesses, improving the flexibility of the device and increasing the processing quality and efficiency.

[0024] When the first bevel gear 5 is not meshed with the second bevel gear 16, the motor 9 of this device can drive the fixed roller 3 to rotate, extruding and transporting the metal material. When the first bevel gear 5 is meshed with the second bevel gear 16, the distance between the movable roller 12 and the fixed roller 3 can be adjusted, making the device suitable for processing workpieces of different thicknesses. The flexibility of the device is improved, and the processing quality and efficiency are enhanced. In other words, the motor 9 has multiple functions, as it can both drive the fixed roller 3 and adjust the distance between the movable roller 12 and the fixed roller 3.

[0025] With the setting of the limiting groove 19 and the limiting bar 18, the first bevel gear 5 moves within the limited trajectory to ensure the normal operation of the component.
