Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a rolling mill device. Background Art

[0002] A rolling mill is a key equipment widely used in the field of metallurgy and metal processing. It is mainly used to apply continuous or gradual pressure to the metal billet through one or more pairs of rotating rollers to cause it to undergo plastic deformation, thereby producing various products with specific sizes, shapes and mechanical properties, such as plates, strips, bars, wires, pipes, etc. The structure of a rolling mill usually includes a working base, a prime mover, a transmission mechanism, and an adjustment system. With the advancement of modern industrial technology, today's rolling mills have also incorporated advanced automation control systems and process optimization technologies to improve overall production efficiency, product quality, and achieve better energy-saving and environmental protection effects. In general, rolling mills are an important cornerstone in the modern metallurgical and metal material deep processing industry chain, and play a decisive role in promoting the technological progress and development of related industries.

Since the structure of the rolling mill itself is relatively complex, and the volume and mass of the rollers are relatively large, it is extremely inconvenient to adjust the roller spacing in the rolling mill, which requires a lot of manpower and brings great trouble when changing different processing requirements. Therefore, it is necessary to propose a rolling mill device to solve the above-mentioned problems. Utility Model Content

[0007] Furthermore, in order to realize that the transmission mechanism drives the metal roller to rotate, the transmission mechanism includes a transmission motor fixedly installed on a transmission frame, a driving gear is fixedly connected to the transmission shaft of the transmission motor, a driven gear is rotatably installed on one side of the transmission frame, the driving gear is meshed and connected with the driven gear, one end of the driving gear and the driven gear is fixedly connected to the universal joint, the driving gear and the driven gear are driven to rotate by the transmission motor, and the driving gear and the driven gear drive the metal roller to rotate through the universal joint.

[0008] Furthermore, in order to achieve the stability of the adjustment support frame when the rolling mill device is working, lifting threaded rods are fixedly connected to both sides of the bottom surface of the adjustment support frame, and the surface of the lifting threaded rods is threadedly connected to support columns. By rotating the support columns, the support columns can be moved up and down, thereby stably supporting the adjustment support frame and preventing it from moving through the universal wheels.

[0009] Furthermore, in order to realize that the adjusting rod drives the adjusting tube to rotate, bevel gear one is meshed with bevel gear two, and the bevel gear two is driven to rotate by rotating the adjusting rod, and bevel gear two drives bevel gear one and the adjusting tube to rotate.

[0010] Furthermore, in order to facilitate the rotation of the adjusting rod and the supporting column, a twisting column is fixedly connected to the surface of the adjusting rod and the supporting column.

[0011] Furthermore, in order to prevent the metal material after extrusion by the rolling mill from falling and causing damage to the adjusting rod, a blanking plate is fixedly installed on one side surface of the adjusting support frame.

[0012] Furthermore, in order to control the switch of the transmission motor, a control switch is fixedly mounted on one side of the surface of the transmission frame.

[0013] The beneficial effects of the utility model are as follows: by twisting the adjusting rod, the bevel gear two drives the bevel gear one and the adjusting tube to rotate; after the adjusting tube rotates, it is threadedly connected with the threaded transmission rod, so that the two threaded transmission rods on both sides of the bottom of the adjusting support frame move relatively; after the adjusting support frame moves through the universal wheel at the bottom, the two metal rollers are driven to move relatively, thereby changing the processing distance between the metal rollers, so that the adjustment of the roller spacing is simpler and more labor-saving when the rolling mill meets different processing requirements.
