The support mechanism 5 includes a hydraulic cylinder 501 arranged on the working frame 1, and a support block 502 arranged on the output end of the hydraulic cylinder 501. A control valve 6 is arranged on the output pipe 703. During the rolling process, the delivery of the coolant can be controlled by the control valve 6, which is convenient and simple. The support plate 8 is rotatably arranged on the working frame 1.

[0026] When rolling the bolt thread, the present embodiment first starts the two rolling mechanisms 2, then passes the unprocessed bolt through the support plate 8, so that the bolt abuts the support block 502, and then starts the moving mechanism 4, which drives the moving plate 3 to move, and the moving plate 3 drives the rolling mechanism 2 connected to it to approach the other rolling mechanism 2. When the rolling mechanism 2 moves to abut the bolt, the two rolling mechanisms 2 abut the bolt. At the same time, the hydraulic cylinder 501 is started, and the hydraulic cylinder 501 drives the support block 502 to move downward, releasing the support for the support block 502. The two rolling mechanisms 2 start to roll the thread on one end of the bolt. At this time, the other end of the bolt is supported by the support plate 8. The support plate 8 rotates with the bolt in the working frame 1 and moves on the sliding groove. The bolt is restricted by the support plate 8 to ensure that the bolt can be normally threaded. While rolling, the cooling mechanism 7 is started to cool the rolling process so that the rolling can proceed normally. After the rolling is completed, one set of rolling mechanisms 2 is moved, the cooling mechanism 7 stops, and then the support plate 8 is slid to pull the rolled bolt out of the support plate 8.

[0030] When rolling threads on bolts in this embodiment, the first motor 201 is started, the first motor 201 drives the rotating shaft 202 to rotate, the rotating shaft 202 drives the rolling roller 203 to rotate, and then the second motor 401 is started, the second motor 401 drives the screw rod 402 to rotate, the screw rod 402 drives the movable plate 3 to move, the movable plate 3 drives another movable plate 3 to follow the movement on the guide rail 403 through the rolling mechanism 2, so that the rolling roller 203 abuts against the bolt, and then the two rolling rollers 203 roll the bolt in the middle and start to roll threads on the bolt; after the thread rolling is completed, the movable mechanism 4 is started to remove the rolling mechanism 2 on it, the rolling of the bolt is released, and then the rolled bolt can be taken out.
