[0002] The sheet metal bending device is a widely used device in the field of sheet metal processing. At present, there are two main processing methods for sheet metal bending with a thickness of 1mm-3mm and a width of less than 200mm: one is to rely on large-scale mechanical equipment. Large-scale equipment is fixed in the workshop and has strict requirements on the working environment. It is necessary to transport the sheets to be processed to a fixed position. The equipment requires special management and maintenance. In addition, the processing parameters and processing quantity are complicated and cannot achieve batch production of workpieces. Large-scale equipment needs to frequently adjust the processing parameters and frequently clamp the sheets to be processed of different specifications.
