Sheet metal bending system

The invention relates to the technical field of metal plate bending, in particular to a metal sheet bending system which comprises a carrying unit, a fixing unit, a control unit, a bending unit and a storage unit. The electromagnet of the carrying unit is electrified to attract the metal sheet; a controller in the control unit controls a telescopic rod in the bending unit to move through gear transmission; in the bending unit, a metal sheet to be bent is bent through movement of a telescopic rod and magnetic force of an electromagnet, and angle bending control is carried out under the driving action of an angle monitor and an unpowered gear. After bending is completed, the sliding block is driven under the action of the compression spring and the extension spring, the chuck is restored, and the chuck is retracted through the telescopic rod; due to the fact that the structure is simple, the manufacturing cost is low, and the spring is used for resetting the clamping head, the use cost is reduced. 本发明涉及钣金折弯技术领域
