[0002] With the rapid development of modern industry, cold-rolled steel plates are widely used in many fields such as automobile manufacturing, household appliances, construction, and electronic equipment due to their good mechanical properties and surface quality. In actual production, cold-rolled steel plates often need to go through processing procedures such as stamping and bending to meet the structural requirements of different parts. Among them, bending forming is one of the key processes, and its processing accuracy and efficiency directly affect the quality and production cost of products. Traditional steel plate bending devices usually use simple molds in combination with hydraulic or pneumatic drives to achieve bending operations, but there are many deficiencies in actual applications. During the bending process, the positioning of the steel plate is not accurate enough, which easily leads to the slipping or misalignment of the steel plate, affecting the bending accuracy; at the same time, during continuous processing, the replacement and positioning of the steel plate take a long time, affecting the overall operation efficiency. In addition, the adjustment method for the bending angle of traditional devices is relatively cumbersome, making it difficult to meet the requirements of bending at multiple angles and restricting the applicable range of the equipment.
