Description

Technical Field

[0001] The utility model relates to the technical field of cold foil rolling mills, in particular to a wrap angle adjustment device for plate-shaped rolled materials. Background Art

[0002] Cold rolling mills and foil rolling mills are equipment that realize the rolling process of electronic aluminum foil. During the rolling process of aluminum foil rolling mills, the quality of the rolled plate is directly related to the wrap angle of the flattening rolls on the rolling mill.

[0003] The front-end device of the current aluminum foil rolling mill is basically finalized. It includes a scraper straight head, pinch rollers, and flattening rollers (the flattening rollers are divided into four rollers or three rollers) arranged in sequence along the rolling direction. In actual production, operators can smoothly use the front-end device to guide the strip head into the rolling mill, but the front-end device generally cannot reasonably adjust the overlap of the flattening rollers for different strip thicknesses. When the flattening rollers are set as three rollers, the rollers on both sides are fixed rollers and the middle roller is a movable roller. Usually, the desired wrap angle (the angle formed by the plate-shaped rolled material and the roller surface) is achieved mainly by adjusting the height of the middle roller, thereby achieving straightening of the plate-shaped rolled material.

[0004] The existing method of raising and lowering the center roller can only be achieved by adding shims to adjust the roller's height, but this barely changes the range of the wrap angle adjustment. Furthermore, adjusting the roller's height by adding shims to the lower portion of the center roller's bearing seat is cumbersome and difficult to implement. Disassembly is complex and presents potential risks. Each adjustment after production is time-consuming, disrupting the smooth progress of production. Therefore, a wrap angle adjustment device for plate-shaped rolled products is urgently needed to address these issues. Utility Model Content

[0005] In order to solve the technical problem that the front-end device of the rolling mill cannot generally reasonably adjust the overlapping amount of the flattening rollers according to different strip thicknesses, the utility model provides a wrap angle adjustment device for plate-shaped rolled materials. The horizontal height of the movable roller can be adjusted by using a cylinder and a pad to meet the wrap angle requirements of different plate-shaped rolled materials.

[0006] The utility model provides an angle adjustment device for plate-shaped rolled materials, comprising a frame and a movable roller and two fixed rollers rotatably arranged on the frame, the movable roller is located between the two fixed rollers, and the movable roller can move up and down relative to the frame, the angle adjustment device also includes an adjustment component, the adjustment component includes an oil cylinder fixedly arranged on the frame and a movable crossbeam slidably arranged on the frame, the telescopic rod of the oil cylinder is fixedly connected to the movable crossbeam and can drive it to move up and down, both ends of the movable roller are rotatably connected to the first bearing seat, each of the first bearing seats is fixedly connected to a connecting plate, one end of each connecting plate is fixedly connected to the movable crossbeam, and a pad is placed between the other end of each connecting plate and the frame, and the pad is located on the outside of the first bearing seat.

[0007] Furthermore, the frame includes at least two support columns, each of which is located on either side of the movable roller. An upper crossbeam is fixed to the top of each support column, and the support column and the upper crossbeam form a "T" shape. The movable roller is located in the middle of the upper crossbeam. The same end of the two fixed rollers is fixed to the upper surface of both ends of the upper crossbeam, and the other end of the two fixed rollers is fixed to the upper surface of both ends of the other upper crossbeam. A fixing groove is provided in the middle of the upper surface of each upper crossbeam, and a pad is placed in the fixing groove. Each connecting plate has an L-shaped structure. The horizontal plate of each connecting plate is fixedly connected to the bottom of the first bearing seat, and the vertical plate of each connecting plate contacts the pad. The thickness of the pad is adjusted to adjust the horizontal height of the movable roller on the frame.

[0008] Furthermore, two protruding blocks are provided on the top of the movable crossbeam, and the two protruding blocks are respectively fixedly connected to the side of the cross plates of the two connecting plates away from the first bearing seat.

[0009] Furthermore, two chute grooves are provided on the sides of the support column, and slide plates are provided on both sides of the movable crossbeam. Each slide plate is embedded in the chute and can move up and down. When the oil cylinder is activated, it drives the movable crossbeam, the connecting plate on the movable crossbeam, the first bearing seat, and the movable roller to move up and down, and also drives the slide plates to move up and down in the chute grooves.

[0010] Furthermore, two racks are disposed opposite each other at the bottom of the movable crossbeam, and a rotating shaft is disposed on the support column, with gears rotatably disposed at both ends of the rotating shaft, each of which meshes with a rack. The coordinated use of the gears and racks makes the movable crossbeam more stable during movement and further improves the synchronization of the overall movement.

[0011] Furthermore, both ends of each fixed roller are rotatably connected to the second bearing seat, and each second bearing seat is fixedly connected to the top of the upper beam.

[0012] Furthermore, a lower cross beam is fixed between the two support columns.

[0013] Furthermore, two oil cylinders are provided, the bottoms of the two oil cylinders being fixedly connected to the lower crossbeam, and the telescopic rods of the two oil cylinders being fixedly connected to the two ends of the bottom of the movable crossbeam. The two oil cylinders are activated synchronously to drive the movable crossbeam, the connecting plate on the movable crossbeam, the first bearing seat, and the movable roller to move up and down.

[0014] Furthermore, the number of the support columns is set to six, and a support column is fixed at the bottom of the middle part and both ends of each upper cross beam.

[0015] Compared with the prior art, the present invention has the following technical effects:

[0016] 1. First, the fixed bearing seat of the movable roller in the previous design is changed to a first bearing seat that can be moved up and down for adjustment. The oil cylinder adjusts the position of the first bearing seat, thereby achieving a wide range of adjustment of the horizontal height of the movable roller, and ultimately adjusting the required wrap angle of the plate rolled material.

[0017] 2. Secondly, the previous design changed the situation where the horizontal height of the movable roller could only be adjusted by adding or removing shims at the bottom of the bearing seat. The first bearing seat is stabilized on the frame by a pad. By adjusting the thickness of the pad, the horizontal height of the movable roller can be adjusted within a small range, and ultimately the required wrap angle of the plate rolled material can be adjusted. In addition, the pad is located on the outside of the first bearing seat. Adding a pad on the outside of the first bearing seat is convenient and quick, and there is no need to disassemble the first bearing seat. This greatly shortens the time required to adjust the height of the movable roller, and ultimately achieves the required wrap angle of the plate rolled material. The horizontal height of the movable roller is adjusted by using the oil cylinder and pad in combination to meet the wrap angle requirements of different plate rolled materials.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 3As shown, a wrap angle adjustment device for plate-shaped rolled materials comprises a frame 1 and a movable roller 2 and two fixed rollers 3 rotatably arranged on the frame 1, the movable roller 2 is located between the two fixed rollers 3, and the movable roller 2 can move up and down relative to the frame 1. The wrap angle adjustment device also includes an adjustment component 4, and the adjustment component 4 includes a cylinder 41 fixedly arranged on the frame 1 and a movable beam 42 slidably arranged on the frame 1. The telescopic rod of the cylinder 41 is fixedly connected to the movable beam 42 and can drive it to move up and down. Both ends of the movable roller 2 are rotatably connected to the first bearing seat 21, and the end of the movable roller 2 is rotatably connected to the bearing in the first bearing seat 21. Each of the first bearing seats 21 is fixedly connected to a connecting plate 43, and one end of each connecting plate 43 is fixedly connected to the movable beam 42. A pad 44 is placed between the other end of each connecting plate 43 and the frame 1, and the pad 44 is located on the outside of the first bearing seat 21. The plate-shaped rolled material generally passes through the bottom of the driven roller 2 and the top of the two fixed rollers 3, so that the plate-shaped rolled material can obtain the desired wrap angle.

[0031] According to the requirements of the wrap angle of the plate-shaped rolled material, the oil cylinder 41 is started, driving the moving beam 42 to move up and down to a certain position. At this time, the connecting plate 43, the first bearing seat 21 and the movable roller 2 on the movable beam 42 are at a certain position, and the oil cylinder 41 no longer drives them to move; at this time, the pad 44 is placed between the other end of the connecting plate 43 and the frame 1, and the other end of the connecting plate 43 and the frame 1 can be fixedly connected (locked) by the pad 44. The locked pad 44 can further stably fix the movable roller 2 on the moving beam 42. It is worth noting that the pad 44 is placed between the connecting plate 43 and the frame 1 only when the movable roller 2 no longer moves up and down.

[0032] First, unlike the conventional design where the bearing seat of the movable roller is fixed, the first bearing seat 21 of this embodiment can be moved up and down for adjustment. By adjusting the position of the first bearing seat 21, the oil cylinder 41 can adjust the horizontal height of the movable roller 2 over a wide range, ultimately achieving the desired wrap angle adjustment for the plate rolled product.

[0033] Secondly, the previous design changed the situation in which the horizontal height of the movable roller could only be adjusted by adding or removing shims at the bottom of the bearing seat. In this embodiment, the first bearing seat 21 is stabilized on the frame 1 by a pad 44. By adjusting the thickness of the pad 44, the horizontal height of the movable roller 2 can be adjusted within a small range, and ultimately the required wrap angle of the plate rolled material can be adjusted. In addition, the pad 44 is located on the outside of the first bearing seat 21. By adding the pad 44 on the outside of the first bearing seat 21, it is convenient and quick, and there is no need to disassemble the first bearing seat 21. This greatly shortens the time required to adjust the height of the movable roller 2, and ultimately achieves the required wrap angle of the plate rolled material.

[0034] The wrap angle adjusting device for the plate-shaped rolled material of the embodiment adjusts the horizontal height of the movable roller 2 by using the oil cylinder 41 and the pad 44 in combination to meet the requirement of the wrap angle of different plate-shaped rolled materials.

[0035] As an implementable mode, the rack 1 comprises at least two support columns 13, the two support columns 13 are respectively located at two sides of the movable roller 2, and each of the support columns 13 is fixed with an upper cross beam 11 at the top, the support column 13 and the upper cross beam 11 form a “T” shape, the movable roller 2 is located at the middle of the upper cross beam 11, the same end of the two fixed rollers 3 is fixed on the upper surface of the two ends of the upper cross beam 11, the other end of the two fixed rollers 3 is fixed on the upper surface of the two ends of the other upper cross beam 11, that is, the two ends of the fixed roller 3 are fixedly connected with the two upper cross beams 11 respectively, and each of the fixed rollers 3 is located between the upper surfaces of the two ends of the two upper cross beams 11, the middle part of the upper surface of each of the upper cross beams 11 is provided with a fixed groove, and the pad 44 is arranged in the fixed groove, each of the connecting plates 43 is in an L-shaped structure, the horizontal plate of each of the connecting plates 43 is fixedly connected with the bottom of the first bearing seat 21, wherein the horizontal plate of the connecting plate 43 and the bottom of the first bearing seat 21 are also locked by a bolt and a nut, and the vertical plate of each of the connecting plates 43 is in contact with the pad 44. The fixed groove supports the pad 44 by giving way. The vertical plate of the connecting plate 43, the upper cross beam 11 and the pad 44 in the fixed groove can also be locked by a bolt and a nut, so that the movable roller 2 is further stabilized on the rack 1. The thickness of the pad 44 is adjusted to further adjust the horizontal height of the movable roller 2 on the rack 1.

[0036] As an implementable mode, the top of the moving cross beam 42 is provided with two protruding blocks 421, and the two protruding blocks 421 are fixedly connected with the horizontal plates of the two connecting plates 43 away from the first bearing seat 21 respectively.
