The second motor 339 is controlled to be turned on to drive the drill rod 338 to rotate, and the drilling part of the end of the frame-shaped raw material 7 is synchronously and automatically drilled through the drill rod 338; When the frame-shaped material 7 is cut and drilled synchronously and automatically, the frame-shaped material 7 is continuously transferred, and the next frame-shaped material 7 is moved below the two cutting and drilling mechanisms 33, and the lowering processing mechanism 3 continues to cut and drill the next frame-shaped material 7 synchronously and automatically; At the same time, the frame-shaped material 7 after the previous cutting and drilling is moved to the position of the bending mechanism 34, and while descending, the frame-shaped material 7 is stuck between the two bending rollers 3431, and then the fourth motor 322 is controlled to drive the second double-headed screw 321 to rotate, driving the bending mechanisms 34 on both sides to slide towards each other, and conversely, the second double-headed screw 321 is controlled to rotate in the opposite direction, driving the bending mechanisms 34 on both sides to slide back to each other, so as to flexibly adjust the spacing between the bending mechanisms 34 on both sides, so as to facilitate the bending processing of different positions of the two ends of the frame-shaped material 7; Subsequently, the fifth motor 352 is controlled to start to drive the driving clamping shaft 351 to rotate, thereby controlling the first worm 348 in the two bending mechanisms 34 to rotate synchronously, driving the first worm wheel 347 to drive the rotating cylinder 3441 to rotate, and then driving the bending frame 344 and the corresponding bending roller 3431 to rotate around the first axis 343 as the axis. Under the limiting action of the other bending roller 3431, the frame-shaped material 7 clamped between the two bending rollers 3431 is synchronously and automatically bent. After the bending process is completed, the frame-shaped material 7 continues to be transmitted for automatic material return, and the subsequent frame-shaped material 7 is automatically cut, drilled and bent, thereby effectively improving the processing efficiency of the entire office desk and chair manufacturing equipment.
