The bending process of the metal plate has two methods, namely a blank pressing method and a die pressing method. At present, an air compression method is basically adopted, and in the process of bending a metal plate, due to the fact that plastic deformation and elastic deformation of materials exist simultaneously, a machined workpiece can rebound, and the size precision and the straightness of the workpiece are affected. The adopted process measures include an angle compensation method, real-time detection parameter data compensation, subsequent pressurization correction and the like, the technical requirement on bending operators is high, the production efficiency is low, and unmanned automatic production cannot be carried out. And because the residual stress of the raw materials, the rolling direction, the thickness tolerance and the surface quality can generate comprehensive influence all the time, the air compression method is difficult to ensure the quality of the precision sheet metal parts.

The metal plate bending processing of the mould pressing method enables the upper mould, the lower mould and the processing plate to be tightly attached, the applied pressure is 3-5 times of that of the air pressing method, so that the sufficient plastic deformation of the material at the bending position is realized, the processed workpiece does not generate resilience, the size precision and the straightness are very high, the shape and position size precision of the workpiece after multiple bending is high, the subsequent welding and assembly are facilitated, the quality stability and the reliability of the workpiece are high, and the compression strength and the bending strength of the workpiece are higher than those of the workpiece of the air pressing method due to the cold work hardening effect.

However, the processing pressure of the die pressing method is large, so that the requirements on tonnage and rigidity of the bending machine are higher, the energy consumption is higher, and most importantly, the pressure is close to the pressure-resistant limit of a die, so that the potential safety hazard is caused. At present, the method is rarely used and is only suitable for bending processing of plates and small workpieces with the thickness of less than 1 mm.
