Problems solved by technology

[0004] Because the precision stainless steel cold-rolled thin strip has the characteristics of high dimensional accuracy, in the process of slitting and cutting, there will be problems such as burrs and camber due to the inappropriate matching of parameters in each link, which will affect the performance of the strip. Seriously, it even affects the service life of electronic products. If the precision stainless steel cold-rolled thin strip is torn during the slitting and slitting process, it will cause waste of raw materials

Abstract

The invention provides a slitting and slitting process for precision stainless steel cold-rolled thin strips. The slitting width of the slitting is 10mm-640mm. , Disc shear gap and disc shear overlap parameters are rationally allocated to realize slitting of precision stainless steel cold-rolled thin strip; compared with the existing technology, this process can effectively reduce the precision stainless steel cold-rolled thin strip in Slitting the size of defects such as burr and camber after slitting, so as to improve the yield of the strip and reduce the waste of metal materials.

Description

technical field [0001] The invention relates to a slitting and slitting process for precision stainless steel cold-rolled thin strips, and belongs to the technical field of slitting and slitting precision steel strips. Background technique [0002] With the rapid rise of my country's smart phone, LCD TV, new energy vehicles, artificial intelligence and other manufacturing industries and the rapid development of aviation, aerospace, petroleum, and transportation, as a raw material industry, the development and improvement of stainless steel strip production technology complement each other ;Different from conventional stainless steel plates and strips, precision stainless steel strips, as high-end products in the field of stainless steel strips, have excellent strength, dimensional accuracy, surface finish and other properties, and are widely used in electronic stamping parts, optical cables, diamond blades, optical Engraving materials etc. [0003] The width of the raw materi...
