[0002] CNC bending machine is a high-precision, high-efficiency automated mechanical equipment that uses CNC technology to bend metal sheets. However, it still has some shortcomings in actual use. For example, when using existing CNC bending machines, it is often necessary to replace bending molds of different shapes according to the design requirements of the sheet. However, the molds are usually directly fixed to the upper and lower workbenches of the machine body with bolts. Although the stability of the mold after installation can be guaranteed, it takes a lot of time to remove the bolts one by one when replacing the mold, which makes the mold replacement process more cumbersome, affecting the sheet processing efficiency to a certain extent.
