Description

Technical Field

[0001] The invention relates to the technical field of cold rolling, and in particular to a cold rolling equipment for steel components. Background Art

[0002] Cold rolling of steel components refers to the process of extruding and deforming steel plates and other metal plates through roller cold rolling equipment or wheel cold rolling equipment during the transportation process to reduce the thickness of the steel plates, or using special convex wheels and concave wheels to bend the steel plates during movement. The cold rolling processing line of steel components in the prior art is usually composed of multiple cold rolling equipment of different models and functions, so that the steel plates can be formed while moving between multiple cold rolling equipment.

[0003] In the process of cold rolling different steel plates, the required processes and steps are also different. Because the construction of the cold rolling processing line is relatively comprehensive, it is mainly used to cope with the comprehensive cold rolling operation of most steel plates. However, some steel plates are lighter in texture and do not have a longer length, so the steps required for cold rolling will be reduced accordingly. Some steel plates also have special cold rolling processing. When cold rolling such shorter steel plates, because the length of the steel plates is shorter, it is necessary to install multiple traction equipment on the cold rolling processing line. However, because the length of this type of steel plate is shorter, in the actual operation process, the operator may cold roll a variety of steel plates in sequence. However, because the cold rolling processes required for different steel plates are not consistent, it is easy to cause the steel plates to move in the cold rolling equipment. The cold rolling equipment needs to stop working and avoid contact with the steel plates. When the steel plates that need to be cold rolled are replaced immediately, the idle cold rolling equipment needs to be readjusted, which greatly wastes the processing time for cold rolling operations on a variety of steel plates.
