[0002] Cold-rolled sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet. Cold sheet is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Since it is rolled at room temperature and does not produce iron oxide, the surface quality of the cold sheet is good and the dimensional accuracy is high. In addition, after annealing, its mechanical properties and process performance are better than those of hot-rolled thin steel sheets. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled thin steel sheets. Cold-rolled thin sheets can be processed by calenders, but most of the existing calenders cannot directly adjust the spacing between the two rollers. When it is necessary to extrude thin plates of different thicknesses, it is necessary to replace rollers of different diameters. The operation is relatively complicated, laborious and labor-intensive, resulting in low processing efficiency. For this reason, we propose a cold-rolled sheet calendering processing device with adjustable gap. Utility Model Content
