[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 and Figures 3-5As shown, to achieve the above objectives, this utility model provides the following technical solution: A large billet rolling fixture, comprising a fixture support frame 1 and a pre-rolling die 2. Support seats 15 are installed on the top and bottom of the front and rear surfaces of one side of the fixture support frame 1. Side seats 5 are installed on the top of the support seats 15 via dovetail grooves 18. A pre-rolling positioning roller A3 is installed in the middle of the side seats 5 on the front surface of the fixture support frame 1, and a pre-rolling positioning roller B4 is installed in the middle of the side seats 5 on the rear surface of the fixture support frame 1. A positioning post 21 is installed at one end of the pre-rolling positioning roller A3, and a pre-rolling die 2 is installed on the outer surface of the positioning post 21. The pre-stamping roller mold 2 has a pre-stamping groove 19 in the middle of its outer surface. One end of the pre-stamping positioning roller B4 is located at the position of the positioning post 21 and has a positioning groove 20. The positioning post 21 is fitted into the positioning groove 20. The positioning post 21 is hexagonal. The positioning post 21 drives the pre-stamping roller mold 2 to rotate. The side seat 5 is equipped with an equipment frame 17 near the dovetail groove 18. An electric telescopic device A16 is installed on one side of the equipment frame 17. The output shaft of the electric telescopic device A16 is connected to one side of the side seat 5 to facilitate the adjustment of the side seat 5, thereby separating the positioning post 21 and the positioning groove 20.

[0028] like Figure 1 and Figure 2 As shown, the tooling support frame 1 has grooves 11 on the top and bottom of the front and rear surfaces in the middle. A slider 10 is installed inside the groove 11. A top seat 12 is installed at the top and bottom of the tooling support frame 1 at the position of the groove 11 by fixing bolts. A secondary roller 7 is installed in the middle of the sliders 10 on both sides. A secondary roller groove 6 is provided in the middle of the outer surface of the secondary roller 7. A hydraulic expansion joint 13 is installed in the middle of the top of the top seat 12. The output shaft of the hydraulic expansion joint 13 is connected to the top of the slider 10. An infrared distance sensor 14 is installed on one side of the top of the slider 10. The position of the slider 10 is sensed by the infrared distance sensor 14, thereby adjusting the gap of the secondary roller 7.

[0029] The working principle of a large billet rolling fixture based on Embodiment 1 is as follows: After the fixture is installed, the heated large billet is moved to the center of the pre-rolling die 2. The pre-rolling die 2 is rotated by the drive mechanism, and the large billet is pre-rolled by the pre-rolling die 2. When maintenance of the pre-rolling die 2 is required, the electric telescopic device A16 is activated. The electric telescopic device A16 drives the side seat 5 to move laterally, thereby separating the positioning column 21 and the positioning groove 20. The pre-rolling die 2 can then be removed from the positioning column 21 for replacement. After the initial rolling is completed, the secondary rolling roller 7 is driven to rotate by the drive mechanism. The large billet is rolled a second time through the secondary rolling groove 6 in the middle of the secondary rolling roller 7. When it is necessary to adjust the gap of the secondary rolling roller 7 and adjust the outer diameter of the large billet, the hydraulic expansion joint 13 is activated. The hydraulic expansion joint 13 drives the slider 10 to move laterally, and the slider 10 drives the secondary rolling roller 7 to move. The position of the slider 10 is sensed by the infrared distance sensor 14. After completion, the material can be rolled a second time by the secondary rolling roller 7. At this point, the working process of this equipment is completed.

[0030] Example 2

[0031] like Figure 6 and Figure 7 As shown, the present invention proposes a large billet rolling fixture. Compared with Embodiment 1, this embodiment further includes: an electric telescopic device B26 is installed on the front surface of one side of the fixture support frame 1 near the top and near the bottom; a movable bearing 25 is installed on the output shaft of the electric telescopic device B26; a fixed column 24 is installed on the inner surface of the movable bearing 25; a drive shaft 23 is installed on the rear surface of one side of the fixture support frame 1 near the top and near the bottom; a forming roller 9 is clamped on the side adjacent to the fixed column 24; a forming groove 8 is provided in the middle of the outer surface of the forming roller 9; a slot 22 is provided in the middle of both sides of the forming roller 9; the fixed column 24 and the drive shaft 23 are clamped in the slot 22; and the end of the fixed column 24 and the drive shaft 23 is hexagonal.

[0032] In this embodiment, the wire after secondary rolling is moved to the position of the forming roller 9. The drive mechanism drives the drive shaft 23 to rotate, and the drive shaft 23 drives the forming roller 9 to rotate. The forming roller 9 and the forming groove 8 roll the material to form it. When the forming roller 9 needs to be replaced or maintained, the electric telescopic device B26 is activated. The electric telescopic device B26 drives the fixed column 24 to move laterally, thereby separating the fixed column 24 and the forming roller 9, so that the forming roller 9 can be removed for maintenance.

[0033] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
