The bending process of Cnc Bending Machine is a precise and efficient operation, which combines advanced CNC technology and mechanical design to achieve high-precision bending of metal sheets. The following is a detailed explanation of the bending process of Cnc Bending Machine:
Preparation stage:
Place the metal sheet on the workbench of Cnc Bending Machine and fix it to ensure that the sheet is in close contact with the lower die without looseness or misalignment.
According to the processing requirements, select the appropriate bending die and install it on the bending machine. The choice of die is usually determined by the thickness of the sheet and the required bending radius.
Pre-bending (back bending):
On the lower die, a V-groove is usually provided. This V-groove cooperates with the upper die to make the metal sheet produce a certain degree of pre-bending before the formal bending. The purpose of pre-bending is to reduce the ups and downs that may occur during the formal bending process and improve the bending accuracy.
Formal bending:
The CNC system controls the relative movement of the upper die and the lower die according to the preset processing parameters. In this process, the upper die moves downward and clamps and bends the metal sheet together with the lower die.
The CNC device and the servo system work together to ensure that the slider moves according to the predetermined path and speed. This allows the angle and shape of the bend to be precisely controlled to meet the processing requirements.
Depending on the processing requirements, multiple bending operations may be required, and each bending will be precisely controlled according to the preset program.
Springback processing:
After the bending is completed, due to the elasticity of the metal sheet, a certain rebound phenomenon may occur. Cnc Bending Machine usually has the function of continuous tightening of pressure to reduce the rebound effect and obtain a more precise bending effect.
Completion and inspection:
After the bending is completed, the Cnc Bending Machine will automatically stop working. At this time, the operator can remove the processed metal sheet and conduct a quality inspection.
If it is found that the bending angle or shape does not meet the requirements, it can be corrected by adjusting the CNC parameters or changing the mold.
In summary, the bending process of the Cnc Bending Machine is a highly automated and precisely controlled process. Through advanced CNC technology and precise mold design, high-precision bending processing of metal sheets can be achieved.
