Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel strip production equipment, and particularly relates to a tension adjusting device for cold rolling of stainless steel strips. Background Art

[0002] Stainless steel strip is an extension of ultra-thin stainless steel plate. It is a narrow and long steel plate mainly produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Stainless steel cold-rolled strip is made from hot-rolled stainless steel strip billets through further cold rolling. Compared with hot-rolled strip, it has higher dimensional accuracy, lower surface roughness, better surface quality, is smoother, and has higher strength. Therefore, thinner cold-rolled strips can be used instead of thicker hot-rolled strips for the same purpose to save steel consumption, which is of great economic significance.

[0003] Chinese Patent with publication number CN 218201203 U discloses a raw material tension device for cold rolling of stainless steel strips. When the strip raw material is unrolled from the unwinding shaft, the strip raw material bypasses the guide shaft under the support frame and is connected to external equipment. Thus, when the strip raw material is subjected to tension, the guide shaft will squeeze the pressure sensor through the shaft seat, and then the tension value of the current strip raw material can be known through the pressure value detected by the pressure sensor, enabling the staff to timely adjust the tension value of the strip raw material. Therefore, the situation that the strip raw material is deformed or even torn due to excessive tension value can be prevented, and finally the protection ability of the device for raw materials is improved. However, this device is not designed with a limiting mechanism and is prone to deviation during winding. Moreover, this raw material tension device for cold rolling of stainless steel strips is not designed with a quick installation structure for the tension roller, and it is not easy to replace after long-term use, with poor practicability.
