[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-3 As shown, a thread rolling device for bolt processing includes: a thread rolling device 1; a feeding guide rail 2 fixed on the thread rolling device 1; a movable plate 3 slidably disposed on the thread rolling device 1, and the movable plate 3 reciprocates when the thread rolling device 1 is running; and two fixed plates 4, both fixed to the side of the movable plate 3, and the two fixed plates 4 are arranged facing each other.

[0036] The thread rolling device for bolt processing also includes a thread rolling structure, which is set between two fixed plates 4. The thread rolling structure includes: an opening 51, which is opened on the side of one of the fixed plates 4; a rotating shaft 52, which passes through the opening 51 and is rotatably installed in the opening 51, with one end of the rotating shaft 52 rotatably connected to the other fixed plate 4; a mounting frame 53, which is fixedly sleeved on the rotating shaft 52; and two thread rolling plates 54, which are both installed on the side of the mounting frame 53. The thread rolling plates 54 are detachably installed on the mounting frame 53. When the mounting frame 53 rotates, the two thread rolling plates 54 on it will rotate synchronously. When the mounting frame 53 rotates 180°, the two thread rolling plates 54 will switch positions, thus realizing the position swapping between the two thread rolling plates 54.

[0037] The thread rolling device for bolt processing also includes a positioning structure, which is set on one of the fixed plates 4. The positioning structure includes: a sleeve 61, which is slidably sleeved on the rotating shaft 52, with the inner surface of the sleeve 61 in contact with the outer surface of the rotating shaft 52; a spring 62, one end of which is connected to the rotating shaft 52 and the other end of which is connected to the sleeve 61; a sleeve plate 63, which is fixedly sleeved on the sleeve 61; two positioning rods 64, both fixed to the side of the sleeve plate 63; and two positioning grooves 65, both opened on the fixed plate 4 where the opening 51 is located. The size of the positioning rods 64 is adapted to the size of the positioning grooves 65. When the operator pulls the sleeve 61, the sleeve 61 slides on the rotating shaft 52. When the sleeve 61 moves, it can drive the sleeve plate 63 to move. The two positioning rods 64 on the sleeve plate 63 will also move with it. This allows the two positioning rods 64 to move out of the two positioning grooves 65. Without the restriction of the two positioning rods 64, the sleeve 61 and the rotating shaft 52 can rotate.
