[0023] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figures 1 to 8 As shown, in this embodiment, a synchronous displacement mechanism of an incoming wire guide and an outgoing wire guide of a rolling mill comprises a rolling mill arch 1, a first guide seat assembly 2, a second guide seat assembly 3, an outgoing wire guide assembly 4 and an incoming wire guide assembly 5. A working roll 6 is arranged on the rolling mill arch 1, and the first guide seat assembly 2 and the second guide seat assembly 3 are respectively mounted on both sides of the rolling mill arch 1. A first screw rod 7 is rotatably connected to the first guide seat assembly 2 in a transverse direction, a first nut 8 is fixed to the first guide seat assembly 2, and the first screw rod 7 is threadedly connected to the first nut 8. A second screw rod 9 is rotatably connected to the second guide seat assembly 3 in a transverse direction, a second nut 10 is fixed to the second guide seat assembly 3, and the second screw rod 9 is threadedly connected to the second nut 10. A bridge sprocket 11 is arranged at the rear end of the rolling mill arch 1, and a transmission sprocket 22 is mounted on the rear ends of the first screw rod 7 and the second screw rod 9, and the bridge sprocket 11 and the transmission sprocket 22 are driven by chain meshing.

[0025] The wire passes through the inlet guide wheel 16 and enters between the upper and lower working rollers 6 of the rolling mill 1. After rolling, it passes through the outlet guide wheel 17 and leaves. When the rolling position needs to be adjusted, the first screw rod 7 is rotated to make the first nut 8 rotate on the first screw rod 7, and the inlet guide assembly 5 is moved laterally. At the same time, during the rotation of the first screw rod 7, a set of bridge sprockets 11, transmission sprockets 22 and chains at the rear are driven to engage with each other, so that the second screw rod 9 also rotates accordingly. Under the action of the second nut 10, the lateral displacement distance of the outlet guide assembly 4 is consistent with the lateral displacement distance of the inlet guide assembly 5, maintaining the alignment state, and realizing synchronous control of the working position of the rollers.

[0026] A first rigid shaft guide rod 12 is laterally mounted on the first guide seat assembly 2, a first linear bearing 13 is mounted on the first guide seat assembly 2, the first linear bearing 13 slides on the first rigid shaft guide rod 12, a second rigid shaft guide rod 14 is laterally mounted on the second guide seat assembly 3, a second linear bearing 15 is mounted on the second guide seat assembly 3, the second linear bearing 15 slides on the second rigid shaft guide rod 14.

[0027] Under the action of the first rigid shaft guide rod 12, the incoming wire guide assembly 5 adjusts the position of the rolled incoming wire material laterally through the first linear bearing 13. Similarly, under the action of the second rigid shaft guide rod 14, the outgoing wire guide assembly 4 adjusts the position of the rolled outgoing wire material laterally through the second linear bearing 15 so that the front and back remain consistent.

[0028] The inlet guide assembly 5 is rotatably connected to an inlet guide wheel 16, and the outlet guide assembly 4 is rotatably connected to an outlet guide wheel 17. When the wires are in and out, the inlet guide wheel 16 and the outlet guide wheel 17 control the left and right positions of the wires.

[0029] A hand wheel 18 is fixed to the front end of the first screw rod 7. By manually rotating the hand wheel 18, the rotation of the first screw rod 7 can be controlled, thereby driving the second screw rod 9 to rotate together, thereby achieving a synchronous adjustment effect.

[0030] The front and rear ends of the first guide seat assembly 2 are both equipped with a first bearing seat, and the first screw rod 7 is connected to the ball bearing 19 on the first bearing seat. The front and rear ends of the second guide seat assembly 3 are both equipped with a second bearing seat, and the second screw rod 9 is connected to the ball bearing 19 on the second bearing seat. Under the action of the first bearing seat and the second bearing seat, the friction generated by the rotation of the first screw rod 7 on the first guide seat assembly 2 is reduced, and the friction generated by the rotation of the second screw rod 9 on the second guide seat assembly 3 is also reduced.

[0031] A tensioning plate 20 is provided on the rear end of the rolling mill arch 1. The tensioning plate 20 adjusts the position along the vertical direction. A tensioning wheel 21 is installed on the tensioning plate 20. The tensioning wheel 21 meshes with the chain for transmission to control the upper and lower positions of the tensioning plate 20, and then control the height of the tensioning wheel 21, so that the chain is kept in a tensioned state for use, and the synchronous adjustment position is more accurate.

[0032] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
