Description

Technical Field

[0001] This utility model relates to the field of aluminum foil rolling mill technology, specifically to a quick roll changing device for a rolling mill. Background Technology

[0002] Aluminum foil rolling mills can roll aluminum foil blanks into aluminum foil rolls of different thicknesses and widths through multiple rolling passes, thereby meeting the needs of different applications. The flattening rolls of the aluminum foil rolling mill can ensure that the aluminum foil can be rolled flat during the rolling process. By pressing the aluminum foil rolled on the sleeve, it is rolled flat under constant pressure, thereby expelling the air between the foil layers and obtaining aluminum foil rolls with appropriate tightness and neat end faces. The flattening rolls are mounted on the flattening roll frame of the rolling mill through bearing seats at both ends.

[0003] After prolonged use, the ironing rolls of aluminum foil rolling mills need to be replaced periodically to ensure the production quality of aluminum foil rolls. Current technology typically involves replacing the ironing rolls using a crane. This requires removing the old roll from above the ironing roll frame and lowering it down using a crane. However, this method necessitates disassembling the aluminum foil rolling mill's outlet fume hood, making ironing roll replacement inconvenient. The disassembly and lifting process is time-consuming and labor-intensive, significantly impacting the mill's start-up time. Summary of the Invention

[0004] This invention addresses the problem of inconvenient replacement of ironing rolls in existing aluminum foil rolling mills by providing a quick roll changing device. This device facilitates the replacement of ironing rolls in aluminum foil rolling mills without the need to disassemble the outlet fume hood. The process of disassembling the ironing rolls is time-saving and labor-saving, reducing the time required to replace the ironing rolls and thus shortening the downtime of the aluminum foil rolling mill and improving its operating efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is: a rolling mill quick roll changing device, including a rolling mill trolley body and trolley side plates arranged on both sides of the rolling mill trolley body. The trolley side plates are provided with openings, and a lifting cylinder is fixedly installed in the openings. The telescopic end of the lifting cylinder is connected to the lifting side plate, and the lifting cylinder is used to drive the lifting side plate to perform lifting and lowering movements.

[0006] Both of the lifting side plates are equipped with a support mechanism at their upper ends. The support mechanism includes a mounting base and a support component connected to the mounting base. The mounting base is sleeved on the upper end of the lifting side plate. The support component includes a support frame, a support block, and a baffle. The upper and lower ends of the support frame are connected to the support block and the mounting base, respectively. The top of the support block has an arc-shaped groove, and the baffle is provided at both ends of the support block. When the lifting side plate moves up and down, the support component can be driven to move up and down through the action of the mounting base, so as to achieve the purpose of moving the support frame and the support block of the support component up and down. When the support component moves up, it can push the bearing seat at the end of the ironing roll out of the mill ironing roll frame, so as to achieve the effect of disassembling the ironing roll. When the support component moves down, it can lower the bearing seat at the end of the ironing roll into the mill ironing roll frame, so as to achieve the effect of installing the ironing roll.

[0007] Furthermore, two L-shaped plates are fixedly installed on the outer side of the trolley side plate, and the two L-shaped plates are arranged opposite to each other; a guide side plate is fixedly installed on the outer side of the lifting side plate and connected to the telescopic end of the lifting cylinder. The two ends of the guide side plate are slidably connected to the two L-shaped plates respectively. The guide side plate cooperates with the L-shaped plates to guide the lifting movement of the lifting side plate.

[0008] Furthermore, the mounting base includes a U-shaped plate, a top clamping plate, and a square sleeve. The U-shaped plate is sleeved on the upper end of the lifting side plate. The top clamping plate and the square sleeve are symmetrically arranged on both sides of the U-shaped plate. A fixing plate connected to the square sleeve is fixedly installed on the top of the U-shaped plate.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1-6 As shown, a quick roll changing device for a rolling mill includes a rolling mill trolley body 1 and trolley side plates 2 disposed on both sides of the rolling mill trolley body 1. The trolley side plates 2 have openings, and a lifting cylinder 4 is fixedly installed within each opening. The telescopic end of the lifting cylinder 4 is connected to a lifting side plate 5. In this embodiment, the openings provide an installation position for the lifting cylinder 4, so that the telescopic end of the lifting cylinder 4 can drive the lifting side plate 5 to move up and down. Support plates are installed on both sides of the rolling mill trolley body 1, and the lifting cylinder 4 is bolted to the support plates.

[0027] Both lifting side plates 5 are equipped with support mechanisms at their upper ends. Each support mechanism includes a mounting base and a support assembly connected to the mounting base. The mounting base is fitted onto the upper end of the lifting side plate 5. The support assembly includes a support frame 14, a support block 17, and a baffle 20. The upper and lower ends of the support frame 14 are connected to the support block 17 and the mounting base, respectively. The top of the support block 17 has an arc-shaped groove, and both ends of the support block 17 are equipped with the baffle 20. In this embodiment, the support assemblies of the two support mechanisms support both ends of the ironing roller. The support frame 14 is detachably connected to the mounting base. Through the action of the mounting base, the lifting cylinder 4 drives the lifting side plate 5 to move up and down, simultaneously driving the support frame 14 to move up and down. The arc-shaped groove provides a position for the support block 17 to support the ironing roller, and also facilitates the support block 17 to lift the ironing roller upwards. The baffle 20 acts as a barrier against the ironing roller located on the support block 17, preventing the ironing roller from falling during replacement.

[0028] The rolling mill trolley body 1 is moved to a position below the flattening roll, aligning the flattening roll with the arc-shaped groove on the support block 17. Then, the lifting cylinder 4 drives the lifting side plate 5 to move upward. The lifting side plate 5, through the mounting seat, drives the support frame 14 and the support block 17 to move upward. The support block 17 pushes the bearing seat at the end of the flattening roll out of the rolling mill flattening roll frame, thus achieving the purpose of disassembling the flattening roll. When installing the flattening roll, the rolling mill trolley body 1 is moved to the rolling mill flattening roll frame. Then, the lifting cylinder 4 drives the lifting side plate 5 to move downward. The lifting side plate 5, through the mounting seat, drives the support frame 14 and the support block 17 to move downward. The support block 17 places the bearing seat at the end of the flattening roll inside the rolling mill flattening roll frame, thus achieving the purpose of installing the flattening roll.

[0029] Two L-shaped plates 3 are fixedly installed on the outer side of the trolley side plate 2, and the two L-shaped plates 3 are arranged opposite each other. A guide side plate 6 connected to the telescopic end of the lifting cylinder 4 is fixedly installed on the outer side of the lifting side plate 5, and the two ends of the guide side plate 6 are slidably connected to the two L-shaped plates 3 respectively. In this embodiment, the L-shaped plates 3 are welded and fixed to the trolley side plate 2, and the guide side plate 6 is welded and fixed to the lifting side plate 5. The cooperation between the guide side plate 6 and the L-shaped plates 3 guides the lifting movement of the lifting side plate 5.

[0030] The mounting base includes a U-shaped plate 7, a top clamping plate 8, and a square sleeve 11. The U-shaped plate 7 is sleeved on the upper end of the lifting side plate 5. The top clamping plate 8 and the square sleeve 11 are symmetrically arranged on both sides of the U-shaped plate 7. A fixing plate 13 connected to the square sleeve 11 is fixedly installed on the top of the U-shaped plate 7. In this embodiment, the top clamping plate 8 and the square sleeve 11 are both welded and fixed to the U-shaped plate 7. The fixing plate 13 is welded and fixed to the U-shaped plate 7 and the square sleeve 11. The fixing plate 13 plays a role in stabilizing and strengthening the connection between the square sleeve 11 and the U-shaped plate 7. A reinforcing tube is also installed between the two square sleeves 11, and the two ends of the reinforcing tube are welded and fixed to the two square sleeves 11 respectively. The mounting base and the lifting side plate 5 are fixed by a nesting method.

[0031] A through hole is provided at the center of the top clamping plate 8, and a fixing nut 9 is provided on the outer side of the top clamping plate 8 corresponding to the position of the through hole. A tightening bolt 10 is provided on the fixing nut 9, and one end of the tightening bolt 10 passes through the through hole and is pushed against the lifting side plate 5. A pin 12 is inserted into the upper part of the square sleeve 11. In this embodiment, the through hole facilitates the tightening bolt 10 to pass through the top clamping plate 8 and be pushed against the lifting side plate 5. The fixing nut 9 is welded and fixed to the top clamping plate 8 and is threadedly connected to the tightening bolt 10. By using the method of pushing the tightening bolt 10 against the lifting side plate 5, the stability of the connection between the mounting base and the lifting side plate 5 can be ensured. The upper part of the square sleeve 11 has a pin hole for the pin 12 to pass through.

[0032] A square post 15 is fixedly installed at the lower vertical end of the support frame 14. The square post 15 is inserted into the square sleeve 11. The square post 15 is provided with a plurality of pin holes 16 that match the pins 12 at intervals. In this embodiment, there are two square posts 15, which are welded and fixed to the bottom of the vertical part of the support frame 14. Each square post 15 has 10 pin holes 16. By inserting the pins 12 into the pin holes 16 at different positions, the height of the support frame 14 and the support block 17 can be adjusted, thereby adjusting the height of the ironing roller by adjusting the support frame 14 and the support block 17, and ensuring that the bearing seat at the end of the ironing roller can be pushed out of the mill ironing roller frame.

[0033] The upper end of the vertical portion of the support frame 14 is fixedly connected to the support block 17, and a rubber pad 18 is provided at the arc-shaped groove. In this embodiment, the support block 17 is welded and fixed to the top of the vertical portion of the support frame 14, and the rubber pad 18 protects the ironing roller, effectively preventing damage to the contact area between the ironing roller and the support block 17.

[0034] Both ends of the support block 17 are horizontally provided with extension plates 19, and the baffle 20 is inclined upwardly at the end of the extension plate 19; both sides of the support frame 14 are provided with reinforcing plates 21 connected to the extension plates 19 and the baffle 20. In this embodiment, both ends of the extension plate 19 are welded and fixed to the support block 17 and the baffle 20 respectively, wherein the included angle between the baffle 20 and the horizontal part of the extension plate 19 is an obtuse angle, so that the baffle 20 can block the ironing roller on the support block 17, thereby preventing the ironing roller from falling off; the reinforcing plate 21 is welded and fixed to the vertical part of the support frame 14, the extension plate 19 and the baffle 20, and the reinforcing plate 21 plays a role in stabilizing and reinforcing the extension plate 19 and the connection between the extension plate 19 and the baffle 20.

[0035] The working principle of this utility model is as follows: Before replacing the flat ironing roll of the aluminum foil rolling mill, first adjust the height of the support frame 14 and the support block 17 of the support assembly to ensure that the support assembly can push the bearing seat at the end of the flat ironing roll out of the rolling mill flat ironing roll frame. Specifically, remove the pin 12, lift the support frame 14 upward, and the square column 15 at the lower end of the vertical part of the support frame 14 moves upward in the square sleeve 11. When the height of the support block 17 reaches the required position, the pin hole 16 on the square column 15 corresponds to the pin hole on the square sleeve 11. Then, insert the pin 12 into the pin hole and the pin hole 16 to restrict the position of the square column 15.

[0036] When replacing the flattening roll of the aluminum foil rolling mill, first move the mill trolley body 1 below the flattening roll so that the flattening roll corresponds to the arc groove on the support block 17. Then, the telescopic end of the lifting cylinder 4 drives the lifting side plate 5 to move upward. The lifting side plate 5 drives the support frame 14 and the support block 17 to move upward through the mounting seat. After the support block 17 contacts the rubber pad in the arc groove, the support blocks 17 of the two support mechanism components support both ends of the flattening roll respectively. The support blocks 17 continue to move upward, gradually lifting the flattening roll until the bearing seat at the end of the flattening roll is pushed out of the mill flattening roll frame. The mill trolley body 1 then moves again, moving the ironing roll to a location where the overhead crane can lift it. The overhead crane lifts the disassembled ironing roll off the support block 17 and then lifts the new ironing roll onto the support block 17. After that, the mill trolley body 1 is moved to the mill ironing roll frame. Then, the telescopic end of the lifting cylinder 4 drives the lifting side plate 5 to move downward. The lifting side plate 5 drives the support frame 14 and the support block 17 to move downward through the mounting seat. After the support block 17 places the bearing seat at the end of the ironing roll into the mill ironing roll frame, the new ironing roll can be installed, completing the mill ironing roll replacement operation.
