Background

The metal bent wire product is an important component of an automobile seat frame, a backrest frame and the like, and the metal strip of the metal bent wire product has small diameter, complex shape and easy deformation. For a long time, in order to improve the production efficiency of steel wire products, reduce the labor cost, and the like, various enterprises are actively researching how to improve the automation level of bent wire production.

The existing wire bending machine comprises a straightening mechanism, a wire feeding mechanism, a bending mechanism and a shearing mechanism, wherein wires are straightened into a straight line shape through the straightening mechanism, are fed to the bending mechanism through the wire feeding mechanism for forming, and are sheared through reversing the wires. In general, the bending mechanism is composed of an inner mold core and an outer mold core, the metal wire enters between the inner mold core and the outer mold core, and then the inner mold core and the outer mold core are rotated to generate relative movement, so that the metal wire can be bent.
