Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, and in particular to a stable two-roll rolling mill. Background Technology

[0002] With the development of life and the progress of technology, the development of rolling mills has brought the metal processing industry into a new field. Rolling mills are equipment that realizes the metal rolling process, and generally refer to the equipment that completes the entire process of rolling material production. There are many types of rolling mills, and two-roll rolling mills are one of them.

[0003] Two-roll mills for metal rolling are generally fixed structures with relatively simple structures. Therefore, it is difficult to adjust the gap between the rolls according to the size requirements of the rolled parts, resulting in relatively poor applicability. For example, a roll gap adjustment mechanism for a rolling mill (publication number CN213223762U) allows the distance between the two rolls to be adjusted through a mechanical structure, but it is very unstable because one end is supported by a spring. Therefore, a stable two-roll mill (publication number CN220277874U) provides rigid support at both ends of the adjustable rolls through parts to ensure the balance of the rolls, thereby ensuring the stability of the rolling mill.

[0004] However, in both of the above schemes, one roll is fixed and the other roll is adjustable. The adjustable roll is directly connected to the motor, which provides rotational torque and support force. However, the motor can only provide torque and cannot provide radial support force. Therefore, the motor in the above two schemes is prone to spindle bending, which can lead to motor failure and damage to the rolling mill. Utility Model Content

[0022] Reference Figure 1-4 A stable two-roll mill includes: a working platform 1 and fixed rolls 2. The fixed rolls 2 are mounted inside the working platform 1 via bearings. Two sets of adjusting conveyor structures are installed on the upper wall of the working platform 1. Adjusting roll structures are movably installed on the outside of the two sets of adjusting conveyor structures. Transmission structures are installed on the rear walls of the two sets of adjusting conveyor structures, and power structures are installed on the rear walls of the transmission structures. The two sets of adjusting conveyor structures include: a conveyor slide 3, a conveyor screw 4, and a driven bevel gear 5. The conveyor slide 3 is installed on the upper wall of the working platform 1. The two ends of the conveyor screw 4 are movably installed inside the conveyor slide 3 via bearings. The driven bevel gear 5 is installed on the upper wall of the conveyor screw 4. A roll motor 14 is installed on the upper wall of the working platform 1, and the drive end of the roll motor 14 is connected to the fixed rolls 2. Four support legs are installed on the lower wall of the working platform 1.

[0023] As a preferred embodiment, the adjusting roll structure further includes: two adjusting sliders 6 and an adjusting roll body 7; the two adjusting sliders 6 are respectively installed on the outside of the carrier screw 4 by means of threads, and the two ends of the adjusting roll body 7 are respectively installed inside the two adjusting sliders 6.

[0024] As a preferred embodiment, the two sets of transmission structures further include: a transmission frame 8, a transmission shaft 9, and a drive bevel gear 10; the transmission frame 8 is installed on the rear wall of the transport slide 3, the transmission shaft 9 is movably installed inside the transmission frame 8 through bearings, and the drive bevel gear 10 is installed on the front wall of the transmission shaft 9, and the drive bevel gear 10 and the driven bevel gear 5 mesh together.

[0025] As a preferred embodiment, the power structure further includes: two drive sprockets 11, a drive chain 12, and a drive motor 13; the two drive sprockets 11 are respectively mounted on the rear wall of the drive shaft 9, the drive chain 12 is mounted on the outside of the two drive sprockets 11, and the drive motor 13 is mounted on the upper wall of the transmission frame 8, with the drive end of the drive motor 13 connected to the drive sprockets 11.

[0026] Working principle: When using this utility model, the operator needs to connect an external AC power supply to this utility model to provide energy for the electrical appliances in this utility model. Then, the operator connects the controller that matches the drive motor 13 and the roll motor 14 to this utility model to provide control logic for the operation of the drive motor 13 and the roll motor 14. When working, the roll motor 14 starts to rotate, and drives the fixed roll 2 to rotate through the coupling, thereby completing the roll processing.

[0027] When it is necessary to adjust the distance between the adjusting roll body 7 and the fixed roll 2, the drive motor 13 is started to rotate, which drives the drive sprocket 11 to rotate. Driven by the drive chain 12, the two drive sprockets 11 can rotate synchronously. The two synchronously rotating drive sprockets 11 drive the driving bevel gear 10 to rotate through the drive shaft 9. Then, through the meshing between the gears, the driven bevel gear 5 is driven to rotate, thereby causing the two carrier screws 4 to rotate synchronously. Under the action of the screw, the two adjusting sliders 6 move linearly in the vertical direction synchronously, thereby driving the adjusting roll body 7 to move in the vertical direction, and thus adjusting the distance between the adjusting roll body 7 and the fixed roll 2.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
