Description

Technical Field

[0001] This utility model relates to the field of bearing installation technology, specifically a BD rolling mill support adjustment structure. Background Technology

[0002] A BD rolling mill is a device used for cold-rolling steel sheets. It has a dual-roll structure, with one roll being the drive roll and the other the support roll. The drive roll, driven by a motor, feeds the steel sheet into the mill and applies pressure, causing the sheet to undergo stretching and bending between the two rolls, thus thinning the sheet to form the desired shape and size. BD rolling mills are commonly used to manufacture industrial products such as thin plates, strips, and steel pipes.

[0003] The BD rolling mill has a twin-roll structure. When installing the roll bearings, a support base is required. The original support base was fastened by direct screws, which required workers to exert great effort to press the bearing into place before they could tighten the screws. This caused workers to become exhausted and fatigued, resulting in low efficiency and an inability to complete the installation quickly. When installing bearings of different diameters, the support base needs to be moved to adjust its height. To reduce wear caused by friction during movement and to ensure smooth movement, workers need to manually add lubricant regularly. This manual lubrication increases the maintenance burden and carries the risk of untimely or missed lubrication.

[0004] The purpose of this invention is to provide an adjustable support structure for a BD rolling mill to solve the problems mentioned in the background art. Utility Model Content

[0005] Therefore, those skilled in the art have provided a BD mill support adjustment structure to solve the problem mentioned in the background art that the original support fastening method is direct screw fastening, which requires workers to exert great effort to press the bearing into place before they can perform the screw fixing operation, resulting in workers being exhausted and fatigued, and the installation process being inefficient and unable to be completed quickly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A BD mill support adjustment structure, comprising: The frame has a sliding groove fixedly opened inside its rear end, and a solid lubricant is fixedly installed inside the sliding groove.

A hydraulic rod is installed inside the fixing plate, an installation sleeve is inserted and connected inside the insertion hole, and a fastening piece is fixedly connected to the upper end of the installation sleeve. A screw rod is fixedly connected to the upper end of the fastening piece. A sliding block is fixedly installed at the rear end of the second mounting ring, and rollers are rotatably connected to both sides of the upper end of the sliding block.

[0009] As a further solution of the present utility model: A mounting plate, the mounting plate is fixedly installed on the upper end of the second mounting ring, a lifting rod is fixedly installed on the upper end of the mounting plate, and spring rods are fixedly installed on both sides of the lifting rod.

[0010] As a further solution of the present utility model: The frame is in a U-shaped structure. The first mounting holes are symmetrically installed on the left and right sides of the first mounting holes with the lower part of the frame as the central reference. The second connecting holes are symmetrically installed on the front and rear sides of the second connecting holes with the first connecting holes as the central reference. The protective plate forms a flange connection between the fixing holes one and the third mounting holes on the front side of the frame.

[0011] As a further solution of the present utility model: The support is flange-connected to the first mounting holes through the connection holes, and the first mounting ring and the second mounting ring have the same structure.

[0012] As a further solution of the present utility model: The fixing plate is of a double-plate structure.

The sliding block is slidably connected to the sliding groove. The rollers are symmetrically installed on the left and right sides of the sliding block with the sliding block as the central reference.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: In this invention, a sliding groove is opened in the long plate of the C-shaped frame, and solid lubricant is added to both sides inside the sliding groove.

[0026] Please see Figure 5 This embodiment provides a technical solution based on Embodiment 1: The second mounting ring 15 is fixedly connected to the upper end of the first mounting ring 14. A limiting plate 16 is fixedly installed at the bottom end of the second mounting ring 15. A fixing plate 17 is fixedly installed at the front of the upper end of the second mounting ring 15, and an insertion hole 18 is fixedly opened inside the fixing plate 17. A hydraulic rod 19 is installed inside the fixing plate 17. A mounting sleeve 20 is inserted and connected inside the insertion hole 18. A fastening piece 21 is fixedly connected to the upper end of the mounting sleeve 20. A screw 22 is fixedly connected to the upper end of the fastening piece 21. A sliding block 23 is fixedly installed at the rear end of the second mounting ring 15, and rollers 24 are rotatably connected to both sides of the upper end of the sliding block 23.

[0027] Mounting plate 25 is fixedly installed on the upper end of the second mounting ring 15. A lifting rod 26 is fixedly installed on the upper end of the mounting plate 25, and spring rods 27 are fixedly installed on both sides of the lifting rod 26.

[0028] The fixing plate 17 has a double plate structure. The mounting sleeve 20 and the screw 22 are rotatably connected through the internal insertion hole 18 of the fixing plate 17. The fastening plate 21 is sleeved on the outer end of the screw 22. The sliding block 23 is slidably connected to the sliding groove 2. The roller 24 is symmetrically installed on the left and right sides of the sliding block 23 with the sliding block 23 as the center reference.

[0029] In this embodiment, the bearing is pre-installed by passing it through the second mounting ring 15. The second mounting ring 15 has an open structure and requires subsequent tightening. Two fixing plates 17 are installed at the front end of the second mounting ring 15, located on both sides of the opening. Each fixing plate 17 has an insertion hole 18. The mounting sleeve 20 is inserted into the insertion hole 18 of the lower fixing plate 17. The screw 22 is passed through the insertion hole 18 of the upper fixing plate 17 and screwed into the lower mounting sleeve 20 for initial positioning. A fastening piece 21 is pre-fitted onto the screw 22 (located at the end outside the upper fixing plate 17). A hydraulic rod 19 is installed between the two fixing plates 17. The hydraulic rod 19 is operated to extend. The two fixing plates 17 are pushed to move towards each other, thereby initially pressing the opening of the second mounting ring 15 and making it grip the outer ring of the bearing. While the hydraulic rod 19 is kept in a pressed state, the screw 22 is rotated with a tool. The rotation of the screw 22 will drive the fastening plate 21 to rotate downward. The fastening plate 21 will press the upper fixing plate 17 and form a rigid connection with the lower fixing plate 17 through the mounting sleeve 20 and the screw 22, thereby finally locking the two fixing plates 17, ensuring that the opening of the second mounting ring 15 is firmly closed, fixing the bearing in place. The hydraulic rod 19 can be held or released. At this time, the bearing is reliably fixed by the fastening mechanism formed by the fixing plates 17 of the second mounting ring 15.

[0030] The working principle of this utility model is as follows: A U-shaped frame 1 is installed on both sides of the rolling mill to support the roll bearing mounting structure. The support 12 at the lower end of the first mounting ring 14 is placed on the lower short side of the frame 1, aligning the connecting holes 13 on both sides of the support 12 with the mounting holes 4 on the lower short side of the frame 1. The support 12 is fixed to the lower short side of the frame 1 via a flange connection. The lifting rod 26 is installed by passing it through the connecting hole 6 on the upper short side of the frame 1. An mounting plate 25 is installed at the top of the second mounting ring 15, and the mounting plate 25 is connected to the lower drive end of the lifting rod 26. The sliding block 23 at the side end is embedded in the sliding groove 2 on the long side of the frame 1. Rollers 24 are installed on both sides of the sliding block 23. Solid lubricant 3 is installed on both sides inside the sliding groove 2 to ensure effective lubrication of the rollers 24 when they slide in the groove, significantly reducing friction and wear, and eliminating the need for manual lubrication. Spring rods 27 are installed on both sides of the lifting rod 26 to serve as a connection and buffer. The bearing is inserted into the opening of the second mounting ring 15. Two fixing plates 17 are installed at the opening of the second mounting ring 15 on both sides of the opening. The hydraulic rod 19 installed between the two fixing plates 17 is activated. The pressure rod 19 pushes the fixing plate 17 inward, thereby initially pressing the opening of the second mounting ring 15 to grip the outer ring of the bearing. Under hydraulic preload retention, the following operations are performed: Insert the mounting sleeve 20 into the through hole 18 of the lower fixing plate 17; pass the screw 22 through the through hole 18 of the upper fixing plate 17 and screw it into the lower mounting sleeve 20; fit the fastening piece 21 and lock the nut on the end of the screw 22 (located on the outer side of the upper fixing plate 17); tighten the screw 22 with a tool, so that the fastening piece 21 presses against the upper fixing plate 17, and the screw 22 and mounting sleeve 20 are then engaged. The connection of the two fixing plates 17 is used to finally rigidly press and lock them, ensuring that the second mounting ring 15 is firmly closed and fixed to the bearing. When it is necessary to install bearings of different diameters or adjust the position, the lifting rod 26 is activated. The lifting rod 26 drives the mounting plate 25, which in turn drives the second mounting ring 15 to adjust its vertical height. During the adjustment process, the second mounting ring 15 slides smoothly along the sliding groove 2 on the frame 1 through its sliding block 23 and roller 24. The solid lubricant 3 in the sliding groove 2 continuously provides lubrication to reduce friction, and the spring rods 27 on both sides provide buffering and stabilize the movement.

[0031] 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.
