Rolling processing mainly refers to the process of obtaining the desired shape and performance of metal forming materials such as plates, strips, bars, and pipes through a certain deformation process under pressure. The metal material is heated to an appropriate temperature to enhance its plasticity and placed in a rolling machine to apply pre-pressure. During the rolling process, the rolling machine is used to apply greater pressure to gradually deform the metal. The rolling device is equipped with rollers, which are driven to rotate by a transmission system. The metal sheet is gradually deformed under the action of the upper and lower rollers.

Uneven cooling may also result in uneven hardness distribution of the sheets. At the same time, there is a certain height between the ground and the calendering device. If the metal sheets fall directly to the ground, they will be damaged to a great extent. Therefore, a calendering device for metal sheet processing is designed. Utility Model Content

The start-up of the micro motor 18 drives the two auxiliary plates 6 to move left and right, thereby increasing the spatial range of movement of the guide ring 8.
[0024] Embodiment 2:
[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, two top rings 17 are provided at the top of the blanking plate body 16, and two bottom rings 14 are provided at the bottom end of the covering plate 4.

[0026] Working principle: Metal sheet rolling is an important metal processing method. Rolling mainly refers to the process of forming sheet metal materials under pressure and undergoing a certain deformation process to obtain the desired shape and performance. The metal material is heated to an appropriate temperature to enhance its plasticity and placed in a rolling machine to apply pre-pressure. During the rolling process, the rolling machine is used to apply greater pressure to gradually deform the metal. The rolling device is equipped with rollers, which are driven to rotate by a transmission system. The metal sheet is gradually deformed under the action of the upper and lower rollers. The cooling of the metal sheet after rolling is very important. Incomplete cooling will cause residual stress inside the metal sheet. These stresses may cause deformation, cracking and warping of the sheet during subsequent processing and use, uneven cooling, and uneven hardness distribution of the sheet. At the same time, there is a certain height between the ground and the calendering device. If the metal sheet falls directly to the ground, it will be greatly damaged. At this time, the staff can start the water pump 11 and the micro motor 18 at the same time, and the coolant stored in the storage box 10 will be guided along the inner surfaces of the auxiliary pipe 12 and the hose 13 to the inside of the two guide rings 8, and then drip along the inner surfaces of the multiple guide strips 9 to the surface of one of the calendering rollers 2. The dripping coolant can continue to flow to the surface of another calendering roller 2, and the coolant can The coolant can cover the surface of the rolled metal sheet, and the coolant can ensure that the sheet dissipates heat evenly during the cooling process. The coolant applied on the surface of the rolling roller 2 will be transferred to the surface of the metal sheet when the metal sheet is rolled, thereby avoiding thermal stress on the metal sheet and improving the quality of the rolled metal sheet. The start-up of the micro motor 18 drives the two auxiliary plates 6 to move left and right, thereby increasing the spatial range of movement of the guide ring 8, and can fully transfer the coolant to the surface of the rolling roller 2 and the metal sheet. After the micro motor 18 is started, it drives the bidirectional threaded rod 5 to rotate synchronously. Since the outer surface of the auxiliary plate 6 is tightly fitted with the inner surface of the cover plate 4, With the rotation of the bidirectional threaded rod 5, the auxiliary plate 6 can only move left and right. With the movement of the auxiliary plate 6, since the hose 13 is made of rubber, it has a certain flexibility. The hose 13 can be compressed, deformed, and stretched. The coolant can continue to be guided to the inside of the guide pipe 7 through the auxiliary pipe 12, and then transmitted to the inner surface of the guide strip 9. The rolled metal sheet will be received by the blanking plate 16. With the inclined blanking plate 16, the blanking speed of the metal sheet is accelerated. The bottom ring 14 and the top ring 17 are connected by the reinforcing ribs 15. The blanking plate 16 is at a fixed angle, which prevents the metal sheet from falling directly to the ground and being damaged to a great extent.
