The plate machine is different, mainly because the upper mold of the present invention can move along the direction perpendicular to the sheet material feeding direction, thereby increasing the space when the sheet material is fed in and out, thereby solving the technical problem of lowering the center of gravity of the machine tool.

Fig. 1 is a structural schematic diagram of an embodiment of the present invention. The technical solution of this embodiment is: a bending machine body 1, a guide rail 23, an upper mold 6, a roller 22, a push-pull cylinder 16 and a reinforcing rib 19, the bending machine body 1 is provided with a column 4, a support 5 and a lower mold 21, a support 5 is provided on the upper end of the column 4, and a guide rail 23 is arranged on the support 5, and the guide rail 23 is set to pass through the reinforcing rib 19 and the bending machine body 1 The upper end of the upper mold 6 is set to be arranged on the guide rail 23 through the bracket, the bracket of the upper mold 6 is set to be connected with the guide rail 23 through the roller 22, the upper mold 6 is set to correspond to the lower mold 21, and the axis of the push-pull cylinder 16 is set To be perpendicular to the feeding and discharging direction of the plate, one end of the push-pull cylinder 16 is set to be hinged to the guide rail 23, and the other end is set to be hinged to the bracket of the upper mold 6.

In this embodiment, the guide rail 23 is set to include a guide rail seat and a monorail, the cross section of the guide rail seat is set to a quadrilateral, and monorails are arranged on both sides of the guide rail seat contacting the support of the upper mold 6, and the monorail is arranged to be connected to the guide rail by bolts. seat connection.

In this embodiment, the upper die 6 is set to include a pressure head 61 and a pressure cylinder 62, and the number of the pressure head 61 and the pressure oil cylinder 62 is set to 196, and the 196 pressure heads 61 are set to be arranged in the bracket of the upper die 6, 196 A pressure head 61 is set to be arranged in a square, and one end of the pressure oil cylinder 62 is set to be hinged with the support of the upper mold 6, and the other end is set to be hinged with the pressure head 61, and the pressure oil cylinder 62 is arranged to be connected with the hydraulic controller of the pressure oil cylinder 62.
