Description

Technical Field

[0001] The utility model relates to the technical field of thin-wall plate rolling machines, in particular to a thin-wall plate rolling machine with adjustable roller diameter. Background Art

[0002] In the existing processing of metal sheets, thin-walled metal sheets are rolled into prefabricated metal cylinders or metal pipes, and then welded in the form of welds. In this process, a special thin-walled plate rolling machine is often required for processing.

[0003] In actual use, the existing thin-walled plate rolling machines usually require adjustment of the distance between the upper and lower rollers during the rolling process in order to meet different requirements for the inner diameter of the rolling during the rolling process. However, this adjustment method has a certain inner diameter adjustment range. When the processing requirements exceed the adjustment range, the problem of exceeding the adjustment range is usually solved by replacing rollers of different diameters. However, the existing roller diameter adjustment is achieved by directly replacing rollers of different diameters. The operation is relatively cumbersome and has a certain impact on the actual adjustment efficiency. Therefore, those skilled in the art provide a thin-walled plate rolling machine with adjustable roller diameter to solve the problems raised in the above background technology. Utility Model Content

[0030] The working principle and use process of this utility model: When the device is actually used:
