[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for using a multi-ring groove combination thread rolling plate, comprising using a multi-ring groove combination thread rolling plate, wherein the core rod is guided by each guide angle of the locking groove tooth plate, the neck break groove tooth plate, the intermediate ring groove tooth plate and the tail ring groove tooth plate; during the initial processing of the core rod, the support table contacts and supports the core rod; after the initial state of the locking groove, neck break groove, intermediate ring groove and tail ring groove of the core rod is formed, it is inlaid with the thread, and then the locking groove, neck break groove, intermediate ring groove and tail ring groove on the core rod are processed simultaneously.

[0007] A multi-ring groove combined thread rolling plate, comprising: A stationary thread rolling plate assembly, and a moving thread rolling plate assembly distributed opposite to the stationary thread rolling plate assembly.

[0008] Both the static thread rolling plate assembly and the dynamic thread rolling plate assembly are composed of a pad, a locking groove plate, a neck break groove plate, an intermediate annular groove plate, and a tail annular groove plate.

[0009] The locking groove tooth plate is provided with locking threads for thread rolling of the locking groove.

[0010] The neck groove tooth plate is provided with neck grooves for neck cutting.

[0011] The intermediate annular groove tooth plate is provided with inter-annular threads for thread rolling of the intermediate annular groove.

[0012] The tail annular groove tooth plate is provided with tail annular threads for thread rolling of the tail annular groove.

[0013] The pad, locking groove plate, neck break groove plate, intermediate annular groove plate, and tail annular groove plate are all provided with guide angles.

[0014] The bottom of the tail annular groove tooth plate is provided with a support platform that contacts and supports the bottom of the support core rod to prevent it from falling down.

[0015] The beneficial effects of this invention are as follows: the core rod is guided by the locking groove plate, the neck groove plate, the intermediate annular groove plate and the tail annular groove plate at various guide angles, and obtains the support table to contact and support to complete the initial processing. This solves the problem that in the early stage of core rod processing, the groove on the core rod has not yet formed a prototype, which makes the position of the core rod easy to change.

[0017] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0018] like Figures 1 to 6 As shown.

[0019] This application discloses a multi-ring groove combined thread rolling plate, comprising: The stationary thread rolling plate assembly 7 and the moving thread rolling plate assembly 8 are distributed opposite to each other, and the stationary thread rolling plate assembly 7 and the moving thread rolling plate assembly 8 simultaneously perform thread rolling on both sides of the core rod 1. The stationary thread rolling plate assembly and the moving thread rolling plate assembly are both composed of a pad block 2, a locking groove plate 3, a neck break groove plate 4, an intermediate annular groove plate 5, and a tail annular groove plate 6.

[0020] The locking groove tooth plate 3 is provided with locking threads, which are used to perform thread rolling on the locking groove 11.

[0021] The broken neck groove plate 4 is provided with broken neck grooves, which are used to perform thread rolling on the broken neck groove 12.

[0022] The intermediate annular groove tooth plate 5 is provided with inter-annular teeth, which are used for thread rolling of the intermediate annular groove 13.

[0023] The tail annular groove tooth plate 6 is provided with tail annular threads, which are used to perform thread rolling on the tail annular groove 14.

[0024] The pad 2 is used to adjust the height.
