The working principle is as follows: when the device is used, all machining processes are automatically controlled to machine through machining programs written in the controller aiming at sheet metal workpieces 23 of various types in advance. During processing preparation, the press fit seat 203 and the bending push plate 12 with the same size and shape are replaced according to the processing requirement of the sheet metal workpiece 23 with the corresponding type, and then the sheet metal positioning device 5 matched with the sheet metal workpiece 23 is replaced, so that the size and the shape of each press fit seat 203 and the bending push plate 12 are customized according to the corresponding processing station of the corresponding sheet metal workpiece 23, and therefore the processing error can be effectively eliminated. When in use, the controller controls the jacking push rod 503 to drive the positioning rod 501 to move to a specified position, at this time, the sheet metal workpiece 23 is placed on the bottom lifting support plate 7 and positioned well with the positioning rod 501, at this time, negative pressure can be generated through the bottom negative pressure pump 15, so that the sheet metal workpiece 28 is tightly adsorbed on the bottom lifting support plate 7 by using the bottom negative pressure suction cup 28, then the positioning rod 501 retracts to a non-working state, the bottom lifting push rod 8 starts to adjust the height of the sheet metal workpiece 23 to enable the sheet metal workpiece 23 to be aligned with the upper part of the bending butt joint platform 16, meanwhile, the direction of the sheet metal workpiece 23 is adjusted by using the sheet metal direction adjusting motor 9, meanwhile, the first linear driving device 17 and the second linear driving device 6 can drive the sheet metal workpiece 23 to move back and forth and back and left and right, so that the corresponding position of the sheet, at this time, the first adjusting push rod 201 at the corresponding position drives the pressing fit seat 203 at the corresponding position to press the corresponding position of the sheet metal workpiece 23, and the bending push plate 12 corresponding to the pressed position can press the sheet metal workpiece 23 to bend the pressed position. In the bending process, firstly, the height of the lifting seat 304 is adjusted through the third adjusting push rod 305, then, the inclination angle of the bending push plate 12 is adjusted through the inclination angle adjusting motor 303, then, the bending push plate 12 can be driven by the second adjusting push rod 302 to upwards extrude the corresponding position of the sheet metal workpiece 23 to be bent to a specified angle, and the left and right positions of the press fit seat 203 can also be adjusted through the third linear driving device 25. After a processing position to be bent on the sheet metal workpiece 23 is processed, the alignment of the next processing position on the sheet metal workpiece 23 with the corresponding pressing fit seat 203 and the bending push plate 12 can be realized through the first linear driving device 17, the second linear driving device 6 and the sheet metal direction adjusting motor 9 again, so that each position to be bent on the sheet metal workpiece 3 is processed in sequence.
