In order to choose the lowest onnage specifiction,itis best to plan for a bening radus larger than the thickness of the material, and use the free bending method as much as posible When the bending radius is large, it often does not affect the quality of the finished part and its future use. Bending accuracy requirements are a factor that needs to be carefully considered. It is this factor that determines the need to consider a CNC bending machine or a manual bending machine. If the bending accuracy is required to be ±1 and cannot be changed, the CNC machine must be focused.
Hydraulic press brake machines are divided ito manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization method, hydraulic bending machines can be divided into: torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization.According to the movement mode, hydraulic bending machine can be divided into up-moving typ and down-moving type.
As far as free bending is concerned, punch and die are procese at 85 or les (saler i better). When using this set of molds, pay attention to the ga beteen the male mold and the female mold at the bottom of the stroke, and the excessive bending that is sufficient to compensate for the springback and keep the material at about 90°. Generally, the springback angle of the free bending die on the new bending machine is s2, and the bending radis is equa to 0.156 times the opening distance of the die. For the bending of bottomed concave molds, the mold angle is generally 86 ~ 90°. At the bottom of the stroke, there should be a gap slightly larger than the thickness of the material between the male and female molds. The forming angle is improved because the bottomed die has a larger bending tonnage (about 4 times that of free bending), which reduces the stress that usually causes springback in the bending radius.
The experts of the world machinery have been dealing with the numerical simulation of forming processes in straightening machines for many years. For this reason, powerful simulation orogrammes are available today with which optimal configurations can be determined for the respective applications. The software has been validated by means of extensive experimental investigations so that the optimum straightening roll diameters can be determined for a specific area of application.
