Background

Bending is an essential process in the machining process of modern enterprises, so the importance of the bending machine is self-evident. A bending machine is a machine used to bend parts, generally parts being made of metal, but also small portions of other materials. At present, a bending machine is generally driven by a hydraulic pressure, an air pump and a motor to bend a component, and the component is taken out after being deformed so as to obtain a desired result. The technology of benders for metal parts is well established, but there are various problems that arise when parts of other materials are involved. With the advent of more and more complex materials and structures, more and more materials need to be bent directly. The bending machine for new materials or complex structures is not easy to invent because the materials or parts can be damaged if the existing bending machine is used for bending.

In actual operation, a worker only needs to put a television screen on the television screen, and the television screen wire can be prevented from being broken within a certain limit. However, the Chinese utility model adopts the special structure and material properties of the television screen wire, and has no migration capability.

At present, at home and abroad, a device which can be generally applicable and can protect a circuit board in a bending process is not available, therefore, the terminal bending machine for the circuit board is designed, the mechanism can bend a melting point on the circuit board and protect the circuit board, the bending efficiency of the circuit board is improved, the circuit board is well protected, and the terminal bending machine has practical significance and good application prospect.
