Novel electrohydraulic servo follow-up material carrier used for numerical control plate bender

The utility mode provides a novel electrohydraulic servo follow-up material carrier used for a numerical control plate bender, which relates to a material carrier used for a bender. The material carrier includes a control device and a drive device; the drive device includes a drive table connected with a bender frame through linear guide rails, the linear guide rails includes a longitudinal linear guide rail enabling the drive table to move up and down and a traversal linear guide rail enabling the drive table to move back and forth, and a hydraulic drive device is arranged on the drive table and is driven by a link mechanism to rotate with a material carrier rack in contact with plates; and the drive device includes an angle sensor arranged on the material carrier rack, signals sensed by the angle sensor are processed by a controller, the controller controls the oil output through controlling the opening degree of a proportional servo valve arranged on a hydraulic oil cylinder, and the rotating angle of the material carrier rack and the rotating angle of plates are conformed. The utility model has the advantage that the material carrier rack can run along with bent plates.
