[0027] In the existing technology, there are two main methods for bending medium and thick plate materials with a thickness of 12mm to 20mm. One is to use a super-large tonnage CNC bending machine, which has a high investment cost and a small actual demand; the other is to use a hydraulic press in conjunction with a forming mold. One type of workpiece requires a corresponding forming mold, and there are many types of molds, which increases management costs and mold design and production costs.
