The frame is composed of oil tank, bracket, workbench, left and right wall panel and slide block, which ensures the structural strength of the frame. After welding, it is processed on the large floor boring and milling machine after stress removal. In particular, the slide block adopts vertical processing technology (because the working state of the slider is vertical) so as to ensure the straightness of the upper die mounting surface of the slider in the working state.
The machine has higher labor productivity and higher accuracy of bending metal plate, using different shapes of the upper and lower mold, can be bent into various shapes of the workpiece, the slider stroke can be a sheet material for a bending forming, after multiple bending can be obtained more complex shape of the workpiece, when equipped with the corresponding equipment, can also be used for punching.
