Description

Technical Field

[0001] The present invention relates to the technical field of rolling equipment, in particular to a magnesium alloy plate rolling device with a polishing function. Background Art

[0002] Rolling devices play a vital role in the production and processing of magnesium alloy sheets. With the continuous development of industrial technology, the surface quality requirements for magnesium alloy sheets are increasing day by day. Polishing, as a key process to improve the surface quality of the sheets, and its coordinated operation with rolling devices are increasingly attracting attention.

[0003] Rolling devices play a vital role in the production and processing of magnesium alloy sheets. With the continuous development of industrial technology, the surface quality requirements for magnesium alloy sheets are increasing day by day. Polishing, as a key process to improve the surface quality of the sheets, and its coordinated operation with rolling devices are increasingly attracting attention.

[0004] At present, the magnesium alloy sheet rolling devices with polishing functions commonly found on the market can only be set at one position at the exit or entrance of the rolling device during installation. Once installed, its position is difficult to flexibly adjust. In actual production, due to different customer needs and differences in product application scenarios, there are often diverse polishing requirements. For example, some products may require pre-treatment polishing when the plate just enters the rolling device to remove impurities and unevenness on the original surface, while other products may require final fine polishing after roll forming to achieve a higher surface finish standard.

[0005] When faced with these varying polishing requirements, moving the polishing unit from one entrance to the other requires disassembling and reassembling the entire unit. This process is not only labor-intensive, material-intensive, and time-consuming, but can also lead to wear and tear of component parts due to frequent disassembly and reassembly, impacting the overall lifespan and stability of the equipment, ultimately reducing production efficiency and increasing costs.

[0006] Therefore, it is of great practical significance to develop a magnesium alloy sheet rolling device that can flexibly adjust the position of the polishing device to adapt to different polishing requirements. Summary of the Invention

[0007] The purpose of the present invention is to solve the shortcomings of the existing polishing device, such as the inability to adjust the position, resulting in a large amount of manpower, material and time costs, and the possible wear of the device parts due to frequent disassembly and installation, affecting the overall service life and stability of the equipment, thereby reducing production efficiency and increasing production costs. A magnesium alloy plate rolling device with polishing function is proposed.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0018] 2. When the present invention is in use, the cooling component provided allows the low-temperature coolant circulation pump to extract the coolant from the water storage chamber and transport it to the moving block through the connecting hose, and then spray it onto the upper and lower surfaces of the magnesium alloy plate through the nozzle. The sprayed coolant then falls into the filter tank and, after being filtered in the filter tank, continues to fall into the water storage chamber below for recycling, thereby fully cooling the surface of the magnesium alloy plate after rolling. The used coolant can also be filtered and reused, greatly saving the use cost. BRIEF DESCRIPTION OF THE DRAWINGS
