[0026] In the present utility model, the left combined plate, the right combined plate and the middle combined plates can be combined to form the thread rolling plate main body through the thread rolling plate fixing structure. When local thread teeth of the thread rolling plate main body formed by the left combined plate, the right combined plate and the middle combined plates are damaged, the maintenance cost of the thread rolling plate main body in the later stage can be reduced by replacing the combined plate at the corresponding position. Secondly, the length of the thread rolling plate main body can be adjusted correspondingly according to requirements by increasing or decreasing the number of the middle combined plates.

[0027] Specifically, the left combined plate 2, the right combined plate 3 and the middle combined plates 4 are all made of combined plate main bodies with the same shape and size, and the thread tooth combined parts 6 are arranged on the combined plate main bodies.

The structure of the connecting part and the notch part is adopted at the connecting position of the thread tooth combined parts, which can reduce the influence of the gap at the splicing position and make the thread teeth more integral.

[0029] Specifically, the left end of the thread combination part 6 on the left combined plate 2 is flush with the left end face of the left combined plate 2, and the right end of the thread combination part 6 on the right combined plate 3 is flush with the right end face of the right combined plate 3.

[0030] Specifically, the thread rolling plate fixing structure 7 includes a thread plate fixing plate 10 having a thread plate mounting groove 9. The combined plate body is slidably disposed in the thread plate mounting groove 9. The left side of the thread plate mounting groove 9 has an opening, and a left baffle 11 is provided on the opening side of the thread plate mounting groove 9. The combined plate body can be inserted into the thread plate mounting groove through the opening of the thread plate mounting groove. After installation, the opening of the thread plate mounting groove is blocked by the left baffle.

[0031] Preferably, a horizontal limiting structure is provided at the bottom of the thread plate mounting groove 9, and limiting pressing plate structures are further provided on both sides of the thread plate mounting groove 9. The horizontal limiting structure and the limiting pressing plate structures can limit the combined plate body to prevent the combined plate body from loosening during the thread rolling operation.

[0032] Specifically, the horizontal limiting structure includes a protruding limiting slider 12. The bottom of the combined plate body is recessed inwardly to form a limiting sliding groove 13. The cross sections of the limiting slider 12 and the limiting sliding groove 13 are T-shaped. The limiting slider with a T-shaped cross section cooperates with the limiting sliding groove to limit the combined plate body.

[0033] Specifically, the limiting pressing plate structure includes a vertical sliding groove 14 recessed inwardly at the top of the inner side wall of the thread plate mounting groove 9. A limiting pressing plate 15 is slidably disposed in the vertical sliding groove 14. Pressing plate grooves are recessed inwardly on both sides of the combined plate body. A lifting screw 16 is rotatably connected in the vertical sliding groove 14, and the lifting screw 16 is screwed with the limiting pressing plate 15. For the convenience of installing the combined plate body, there is a certain gap between the limiting slider and the limiting sliding groove. After the combined plate body is installed, the limiting pressing plate can be inserted into the pressing plate groove, and rotating the lifting screw can drive the limiting pressing plate to move downward to press the combined plate body to prevent the combined plate body from loosening during the thread rolling operation.

[0034] Preferably, a guide rod vertically disposed and slidably connected to the limiting pressing plate 15 is further provided in the vertical sliding groove 14. The guide rod can limit the limiting pressing plate.

[0035] Specifically, the left baffle 11 is detachably fixed to the thread plate fixing plate 10 by bolts.

[0036] The working principle of the present utility model is as follows: The left combined plate, the right combined plate, and the middle combined plate can be combined to form the main body of the thread rolling plate through the thread rolling plate fixing structure. When the thread teeth at a local part of the main body of the thread rolling plate formed by the left combined plate, the right combined plate, and the middle combined plate are damaged, the maintenance cost of the main body of the thread rolling plate in the later stage can be reduced by replacing the combined plate at the corresponding position. Secondly, the length of the main body of the thread rolling plate can be adjusted correspondingly according to the requirement by increasing or decreasing the number of the middle combined plates;

[0037] The structure of the connecting part and the notch part is adopted at the connecting position of the thread tooth combination part, which can reduce the influence of the gap at the splicing position and make the thread teeth more integral;

[0038] The combined plate main body can be inserted into the thread plate installation groove through the opening of the thread plate installation groove. After the installation is completed, the opening of the thread plate installation groove is blocked by the left baffle. The horizontal limiting structure and the limiting pressure plate structure can limit the combined plate main body to prevent the combined plate main body from loosening during the thread rolling operation. The limiting sliding block with a T-shaped cross-section and the limiting sliding groove can limit the combined plate main body. In order to facilitate the installation of the combined plate main body, there is a certain gap between the limiting sliding block and the limiting sliding groove. After the combined plate main body is installed, the limiting pressure plate can be inserted into the pressure plate groove. Rotating the lifting screw rod can drive the limiting pressure plate to move downward to press the combined plate main body to prevent the combined plate main body from loosening during the thread rolling operation. The guide rod can limit the limiting pressure plate.
