Description

Technical Field

[0001] The utility model relates to the technical field of rolling mills, and more specifically, to a material pushing device for a rolling mill. Background Art

[0002] A rolling mill is a piece of mechanical equipment mainly used for processing metal materials, especially for pressing and deforming metal materials to form the required shape and size of parts.

[0003] Rolling mills mainly rely on two or more rollers rotating relative to each other. When metal materials are fed between the rollers, the rotation of the rollers and the pressure applied will cause the metal materials to undergo plastic deformation. This deformation is achieved through repeated rolling of the rollers and multiple deformations of the metal materials, ultimately forming the desired parts.

[0004] When a rolling mill is performing production and processing operations, it is usually necessary to use a pushing device to push heavier metal objects into the processing area of ​​the rolling mill while ensuring the safety of the workers. In order to reduce the friction of the metal and make it easier to push the metal material, the metal material is usually supported by multiple sets of rollers. However, in actual use, the pushing device usually needs to adjust the direction of the metal material before performing the pushing operation so that the metal material and the feed port of the rolling mill are aligned with each other. However, the weight of the metal material is relatively high, which increases the difficulty of the adjustment operation, and it is impossible to ensure that the metal material and the rolling mill are perpendicular to each other, which causes the metal material to shift, further causing the metal sheet pressed by the rolling mill to have errors in shape and curvature, which affects the product quality, and therefore needs to be improved and optimized.

At this time, the material and the feed port of the rolling mill 1 are aligned with each other and perpendicular to the rolling mill 1. After the calibration is completed, the staff starts the motor 17 to make the adjusting roller 13 and the material conflict with each other. After the adjusting roller 13 and the material conflict with each other, the rotating disk 15 stops rotating. At this time, the second transmission shaft 23 will apply pressure to the first transmission shaft 21, so that the first transmission shaft 21 moves downward along the transmission rod 20.

[0032] After the calibration is completed, the staff starts the motor 17 to make the adjusting roller 13 and the material collide with each other. After the adjusting roller 13 and the material collide with each other, the rotating disk 15 stops rotating. At this time, the second transmission shaft 23 will apply pressure to the first transmission shaft 21, so that the first transmission shaft 21 moves downward along the transmission rod 20.

[0039] The transmission rod 20 and the first transmission shaft 21 are movably connected, and the outer wall of the transmission rod 20 is provided with a protrusion, and the interior of the first transmission shaft 21 is provided with a groove matching the protrusion. The transmission rod 20 and the first transmission shaft 21 are connected by transmission through the protrusion and the groove.

[0040] The first transmission shaft 21 can slide on the surface of the transmission rod 20 and transmit the rotational power through the cooperation of the protrusion and the groove.

[0041] The adjusting roller 13 is made of rubber to prevent the material from being damaged.

[0042] The working principle and use process of this utility model:

At this time, the rotating disk 15 rotates, and at the same time, the two groups of moving plates 11 are pulled inward through the connecting rod 16. The moving plate 11 will pass through the moving block 10 and move along the guide rod 9. At this time, the extension rod 12 on the top of the moving plate 11 will move along the interlayer between the rollers 6, and make the adjusting roller 13 and the material conflict with each other. The adjusting rollers 13 on the left and right sides will push the material Move to the center of the bracket 3, and then the staff starts the motor 17 to reverse the output shaft of the motor 17 and reset the adjusting roller 13. At this time, the staff can start the motor 17 multiple times to make the adjusting roller 13 calibrate the offset of the material multiple times.
