Description

Technical Field

[0001] The present invention belongs to the technical field of cold rolling mill rolling production, and particularly relates to a non-driven roll mounting support and a using method thereof. Background Art

[0002] In cold rolling mill equipment, there are some non-driven rolls running online, such as degreasing rolls, turning rolls, etc. During the production of modern high-speed rolling mills, the inspection and replacement frequencies of such rolls are also increasing day by day.

[0003] In traditional cold rolling mills, such rolls generally use bolts to fasten the roll bearing seat to the rolling mill. When inspecting and replacing the rolls, the bolts need to be removed and then the rolls are removed. When the rolls are reset, the rolls are first positioned and then bolted to the rolling mill. The entire roll changing process is time-consuming and laborious, and the efficiency is extremely low. Summary of the Invention

[0004] The purpose of the present invention is to provide a non-driven roll mounting support to overcome the technical problems existing in the prior art.

[0005] Another purpose of the present invention is to provide a using method of the non-driven roll mounting support, which can quickly and efficiently remove and reset the roll from the rolling mill.

[0006] Therefore, the technical solution provided by the present invention is as follows:

[0007] A non-driven roll mounting support includes a limit block, a base with a track, a roll frame, a roll, and a pushing device. The roll, the roll frame, and the base with a track are connected in sequence from top to bottom. The roll is fixedly connected to the roll frame. The roll frame is slidably connected to the base with a track. The pushing device is located at one end of the roll frame. The other end of the roll frame is axially limited by the cooperation of the limit block and the base with a track.

[0008] One end of the base with a track is provided with a limit groove. The pushing device is installed at the other end of the base with a track. The limit groove cooperates with the limit block.

[0009] The roll frame includes a roll frame body, vertical roller wheels, and side roller wheels. The roll frame body includes a flat plate and a vertical plate. The cross-section of the flat plate and the vertical plate after connection is a T-shaped structure. The vertical roller wheels and the side roller wheels are both in multiple groups and symmetrically arranged on both sides of the vertical plate. The distances between adjacent two vertical roller wheels on the same side of the vertical plate are all unequal.

[0010] The cross-section of the base with a track is a U-shaped structure. The base with a track includes a long groove and a positioning surface. The long groove is arranged inside the base with a track. The positioning surface is located at the top of the long groove. The two side surfaces of the long groove are guiding surfaces. The lower surface of the long groove is a roll changing track. The roll changing track is provided with U-shaped grooves with unequal distances. The U-shaped grooves match and correspond to the vertical roller wheels one by one;

[0011] The positioning surface is in contact with the lower surface of the flat plate. The vertical roller wheels are slidably connected to the roll-changing track, and the side roller wheels are slidably connected to the guiding surface.

[0012] Bearings are provided on both sides of the roller. The bearings are fixedly connected to the upper surface of the flat plate of the roller frame, and a handle is provided on one of the bearings.

[0013] The pushing device is a cylinder or an oil cylinder, and a push block is installed on the piston rod of the pushing device.

[0014] A first shaft hole and a convex block are provided on the vertical plate. The convex blocks correspond to the side roller wheels one by one. A set of vertical roller wheels is symmetrically arranged on both sides of the vertical plate through the wheel shaft passing through the first shaft hole.

[0015] The convex blocks are symmetrically arranged on both sides of the vertical plate. Grooves and second shaft holes are provided on the convex blocks. The side roller wheels are arranged in the grooves. The second shaft holes penetrate the upper and lower ends of the grooves. The axial directions of the vertical roller wheels and the side roller wheels are perpendicular.

[0016] The widths of the two side surfaces of the long groove are equal to the widths of the outer tangent surfaces of the two side roller wheels, and the height of the long groove is greater than the roller diameter of the vertical roller wheel.

[0017] A method for using a non-driving roll mounting support. When the roll is working normally, the roller frame is located in the long groove of the base with a track. All the vertical roller wheels of the roller frame are suspended and sunk in the U-shaped groove of the roll-changing track of the long groove. The roller frame realizes the positioning in the height direction by the lower surface of the flat plate of the roller frame body closely adhering to the positioning surface, so as to ensure the flatness tolerance of the roll. At the same time, all the side roller wheels closely adhere to the guiding surface to realize the positioning of the roll in the rolling direction of the rolling mill, so as to ensure the parallelism tolerance between the roll and other rolls of the rolling mill. The axial direction of the roller frame is axially limited by the cooperation of the limiting block and the base with a track.

[0018] When the roll is taken out during the roll-changing operation, the limiting block is taken out from the base with a track. The pushing device abuts against the end face of the roller frame. The vertical roller wheels are pushed out of the U-shaped groove of the roll-changing track, so that the wheel surfaces of the vertical roller wheels fall on the roll-changing track. At this time, the lower surface of the flat plate of the roller frame body of the roller frame is separated from the positioning surface of the base with a track, and then the whole roller frame and the roll are pulled out of the rolling mill and lifted away by the workshop overhead crane.

[0019] When the replaced roll is reset, the workshop overhead crane is used to lift the roller frame and the roll as a whole to the side of the base with a track. The vertical plate of the roller frame is aligned with the long groove, the roll is pushed into the reset position, and then the axial limit is carried out through the limiting block to complete the roll change.

[0020] The beneficial effects of the present invention are:

[0021] For the non-driving roll mounting support provided by the present invention, when the roll is working normally, the roll frame is located in the long groove of the base with a track. All the vertical roller wheels of the roll frame are suspended and sunk in the U-shaped groove on the roll-changing track surface of the base with a track. At this time, the roll frame is positioned in the height direction by the lower surface of the flat plate of the roll frame body closely adhering to the upper surface of the base with a track, so as to ensure the flatness tolerance of the roll. All the side roller wheels on both sides of the roll frame closely adhere to the guiding surfaces on both sides of the long groove, realizing the positioning of the roll in the rolling direction of the rolling mill, so as to ensure the parallelism tolerance between the roll and other rolls of the rolling mill.

[0022] The present invention axially locks the roll frame by inserting the limit block into the limit groove of the base with a track, realizing the axial positioning of the roll.

[0023] By arranging U-shaped grooves with unequal intervals on the roll-changing track, it can be ensured that at least two pairs of vertical roller wheels fall on the roll-changing track of the base with a track during the process of moving the roll frame and the roll out of the rolling mill. This enables the operator to easily pull the entire roll frame and the roll out of the rolling mill through the handle on the roll bearing seat.

[0024] The entire roll-changing operation of the present invention is fast and efficient. After resetting, insert the limit block into the limit groove, and the roll can start working without adjustment.

Among them, the limit block 1 is a steel rectangular block.

[0048] Embodiment 3:

[0049] This embodiment provides a non-driving roll mounting support, including a limit block 1, a base 2 with tracks, a roller frame 3, a roller 4 and a pushing device 5.

[0061] The pushing device 5 is a gas cylinder or an oil cylinder, and a pushing block is mounted on the piston rod of the pushing device 5.

[0062] The pushing device 5 is installed on the other side of the base 22 with the track (the opposite side of the moving-out side), and is a short-stroke air cylinder or oil cylinder. A push block is installed on the piston rod of the pushing device 5. When the roller 4 is working, the push block does not contact the roller frame body 8. When the roller is changed, the piston rod of the pushing device 5 is pushed out, and the push block pushes the roller frame 3 out of a certain stroke. This stroke can ensure that the vertical roller wheel 6 is pushed out of the U-shaped groove 21 of the roller changing track 10.

[0063] Embodiment 7:

[0064] On the basis of Example 5, this embodiment provides a non-transmission roller mounting support, wherein the vertical plate 14 is provided with a first axial hole 16 and a protrusion 17, wherein the protrusion 17 corresponds to the side roller 7 one by one, and a group of vertical rollers 6 are symmetrically arranged on both sides of the vertical plate 14 through the wheel axle passing through the first axial hole 16;

[0065] The protrusions 17 are symmetrically arranged on both sides of the vertical plate 14, and the protrusions 17 are provided with a groove 18 and a second axial hole 19, the side roller 7 is arranged in the groove 18, and the second axial hole 19 passes through the upper and lower ends of the groove 18, and the axial directions of the vertical roller 6 and the side roller 7 are perpendicular. Figure 4 shown.

[0066] Embodiment 8:

[0067] This embodiment provides a non-transmission roller mounting support, including a limit block 1, a base 2 with a track, a roller frame 3, a roller 4 and a pushing device 5.

[0068] On both sides of the roller 4, there are bearing seats. Among them, a handle 15 is installed on the bearing seat on the removal side, which is used to push and pull the roller 4 when changing the roller. The bearing seats of the roller 4 are connected to the roller rack 3 through bolts. The roller rack 3 is composed of a roller rack body 8, vertical roller wheels 6 and side roller wheels 7. Among them, the roller rack body 8 is of a T-shaped structure. The upper surface of the flat plate 13 is fixed to the bearing seat of the roller 4 through bolts. On both sides of the vertical plate 14 at the lower part of the roller rack body 8, a number of first shaft holes 16 are machined, and there are also a number of symmetrically distributed convex blocks 17. Grooves 18 and first shaft holes 16 are machined on the convex blocks 17. The vertical roller wheels 6 are symmetrically installed on both sides of the vertical plate 14 by the axis of the wheel, and the distance between every two vertical roller wheels 6 on the same side is different. The side roller wheels 7 are symmetrically installed in the grooves 18 of the convex blocks 17 on both sides by the axis of the wheel.

[0069] The base 2 with a track is of a U-shaped structure. The lower surface of the base is fixedly connected to the rolling mill through bolts. Inside the base, there is a finely machined long groove 9. The two side surfaces of the long groove 9 are the guiding surfaces 12 of the side roller wheels 7, and the width of the two side surfaces is equal to the width of the outer tangent surfaces of the side roller wheels 7 on both sides. The height of the long groove 9 is greater than the roller diameter of the vertical roller wheels 6. The lower surface of the long groove 9 is a finely machined roll-changing track 10. At the positions corresponding to the vertical roller wheels 6 on the track surface, a number of U-shaped grooves 21 are machined, so that all the vertical roller wheels 6 are sunk in the U-shaped grooves 21 when the roller 4 is working. The U-shaped upper surface of the base 2 with a track is a finely machined positioning surface 11. When the roller 4 is working, the lower surface of the flat plate 13 of the roller rack 3 closely adheres to this positioning surface 11 to ensure the flatness tolerance of the roller 4.

[0070] The base 2 with a track has a limit groove 20 on the removal side of the roller 4. The limit block 1 can be clamped into the limit groove 20 when the roller 4 is working to axially lock the roller rack 3. The limit block 1 is a steel rectangular block.

[0071] The pushing device 5 is installed on the other side of the base 2 with a track. It is a short-stroke cylinder or oil cylinder. A push block is installed on the piston rod of the pushing device 55. When the roller 4 is working, the push block does not contact the roller rack body 8. When changing the roller and taking out the roller, the piston rod of the pushing device 5 is pushed out, and the push block pushes the roller rack 3 out for a certain stroke, and this stroke can ensure that the vertical roller wheels 6 are pushed out of the U-shaped grooves 21 of the roll-changing track 10.

[0072] The working principle is as follows:

[0073] When the roller 4 is working normally, the roller rack 3 is located in the long groove 9 of the base 2 with a track. All the vertical roller wheels 6 of the roller rack 3 are suspended and sunk in the U-shaped grooves 21 on the surface of the roll-changing track 10 of the long groove 9. At this time, the roller rack 3 realizes the positioning in the height direction by the lower surface of the flat plate 13 of the roller rack body 8 closely adhering to the upper surface of the base 2 with a track to ensure the flatness tolerance of the roller 4, as Figure 5As shown in the sectional view of the working position. All side roller wheels 7 on both sides of the roller frame 3 are closely attached to the guiding surfaces 12 on both sides of the long groove 9, so as to position the roller 4 in the rolling direction of the rolling mill, and ensure the parallelism tolerance between the roller 4 and other rollers 4 of the rolling mill. For example, Figure 2 As shown. The limiting block 1 is inserted into the limiting groove 20 of the base 2 with a track, axially locking the roller frame 3, and realizing the axial positioning of the roller 4.

[0074] When the roller 4 needs to be replaced, take out the limiting block 1 from the limiting groove 20, extend the piston rod of the pushing device 5, the pushing block abuts against the right end face of the roller frame 3, and the vertical roller wheels 6 are pushed out of the U-shaped groove 21 of the roll-changing track 10. In this way, the wheel surfaces of all the vertical roller wheels 6 fall on the roll-changing track 10 of the base 2 with a track, and the lower surface of the flat plate 13 of the roller frame body 8 of the roller frame 3 is separated from the upper surface of the base 2 with a track, as Figure 6 As shown in the sectional view of the roll-changing position. Since the distances between every two vertical roller wheels 6 on the same side are different, it can be ensured that at least two pairs of vertical roller wheels 6 fall on the roll-changing track 10 of the base 2 with a track during the process of moving the roller frame 3 and the roller 4 out of the rolling mill. At this time, the operator can easily pull the entire roller frame 3 and the roller 4 out of the rolling mill through the handle 15 on the bearing seat of the roller 4. When the roller 4 to be replaced needs to be reset, use the workshop overhead crane to lift the roller frame 3 and the roller 4 as a whole to the side of the base 2 with a track, align the roller frame 3 with the precision-machined long groove 9 in the base, and the operator can easily push the roller 4 into the reset position. After resetting, insert the limiting block 1 into the limiting groove 20, and without adjustment, the roller 4 can start working. The entire roll-changing operation is fast and efficient.

[0075] Embodiment 9:

[0076] This embodiment provides a method for using a non-driving roller mounting support. When the roller 4 is working normally, the roller frame 3 is located in the long groove 9 of the base 2 with a track. All the vertical roller wheels 6 of the roller frame 3 are suspended and sunk in the U-shaped groove 21 of the roll-changing track 10 of the long groove 9. The roller frame 3 realizes the positioning in the height direction by the lower surface of the flat plate 13 of the roller frame body 8 closely attaching to the positioning surface 11, so as to ensure the flatness tolerance of the roller 4. At the same time, all side roller wheels 7 closely attach to the guiding surface 12, realizing the positioning of the roller 4 in the rolling direction of the rolling mill, so as to ensure the parallelism tolerance between the roller 4 and other rollers 4 of the rolling mill, and the roller frame 3 realizes the axial limit through the cooperation of the limiting block 1 and the base 2 with a track.

[0077] Embodiment 10:

[0078] Based on Embodiment 9, this embodiment provides a method for using the mounting support of the non-driving roller. When taking out the roller during the roll change operation, the limit block 1 is taken out from the base 2 with a track, the pushing device 5 is abutted against the end face of the roller frame 3, and the vertical roller 6 is pushed out of the U-shaped groove 21 of the roll change track 10, so that the wheel surface of the vertical roller 6 falls on the roll change track 10. At this time, the lower surface of the flat plate 13 of the roller frame body 8 of the roller frame 3 is separated from the positioning surface 11 of the base 2 with a track, and then the entire roller frame 3 and the roller 4 are pulled out of the rolling mill and lifted away by the workshop overhead crane;

[0079] When the replaced roller 4 is reset, the workshop overhead crane is used to lift the roller frame 3 and the roller 4 as a whole to the side of the base 2 with a track. The vertical plate 14 of the roller frame 3 is aligned with the long groove 9, the roller 4 is pushed into the reset position, and then the axial limit is carried out through the limit block 1 to complete the roll change.

[0080] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present invention, and in practical applications, various changes can be made in form and details without departing from the spirit and scope of the present invention.
