Description

Technical Field

[0001] The utility model relates to the technical field of rolling mill equipment, in particular to a flat head cover disassembly and assembly device. Background Art

[0002] The four-roll mill can be used to process various metals, such as steel, copper, aluminum and other materials. Its advantage is that it can effectively change the form of the metal, such as changing its thickness, width, length and shape. Therefore, it is widely used in various fields such as automobiles, ships, food, and construction. The four-roll mill is mainly composed of upper and lower working rolls, roll stands, transmission mechanisms, hydraulic systems, and electrical systems. Among them, the upper and lower rolls are called working rolls, and there is a set of corresponding support rolls on both sides. They are connected by roll stands and transmission mechanisms, which play a role in deforming the metal when processing the metal. In order to make the metal deform better during the rolling process, the four-roll mill usually uses a flat head cover. The flat head cover consists of four flat heads with different radii. Among them, the two flat heads located on the working roll are called main flat heads, which are used to directly press the metal, and the two flat heads located on the support rolls are called side flat heads, which are used to prevent the metal from lateral deviation during the rolling process and affect the rolling effect.

[0003] Since the flat head cover is easily worn during use, it needs to be replaced frequently. However, the flat head cover is tightly connected to the working roller and has a large size, which makes it difficult to replace the flat head cover.

[0004] In the prior art, Chinese patent CN 115847350 A discloses a plate rolling mill flat head cover quick replacement device and a replacement method thereof, and specifically discloses that the quick replacement device includes a bracket, two upper support plates are symmetrically arranged on the upper part of the bracket, two lower support concave plates are symmetrically arranged on the lower part of the bracket, an upper support mechanism for supporting the upper flat head cover is arranged on the upper support plate, and a first lifting mechanism for driving the upper support plate to rise and fall and a second lifting mechanism for driving the lower support concave plate to rise and fall are arranged on the bracket. When in use, the quick replacement device is placed under the flat head cover to be replaced, the upper flat head cover is placed on the support seat of the upper support plate, and is limited by the upper stop plate; the lower flat head cover is placed on the lower support concave plate, and is limited by the lower stop plate; then the upper support plate is lifted by the lifting cylinder, thereby lifting the upper flat head cover, so that the upper flat head cover is concentric with the roller, providing objective conditions for quick replacement of the flat head cover; and the flat head cover can be automatically limited by the upper and lower stop plates, which is safer and more reliable. The shortcoming of this technical solution is that the existence of the support plate and the stop plate limits the size of the flat head cover, and it can only be used when the model of the flat head cover is fixed, which has limitations.

DETAILED DESCRIPTION

[0022] In order to enhance the understanding of the present invention, the present invention will be described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0023] like Figure 1 and Figure 4The figure shows a flat head cover disassembly and assembly equipment, which specifically includes a support workbench 1 and a disassembly and assembly mechanism. The support workbench 1 is used to place the rollers that need to disassemble or install the flat head cover, and the support seat assembly 11 is placed thereon to support the rollers. The support seat assembly 11 can be two groups, respectively located at the two ends of the support workbench 1, or multiple groups, which can be evenly arranged on the support workbench 1. The support seat assembly 11 is composed of a plurality of V-shaped brackets 12. This V-shaped bracket 12 can not only make the placement of the roller more stable, but also can place rollers of different models, and has a wider range of uses.

[0024] The disassembly and assembly mechanism is located on one side of the supporting workbench, and specifically includes a disassembly and assembly trolley 2 and a trolley driving assembly. A lifting assembly 3 is arranged on the upper part of the disassembly and assembly trolley 2, and the lifting assembly 3 is driven by a hydraulic cylinder to realize up and down movement. A lifting table 31 is arranged on the upper surface of the lifting assembly 3, and a roller rotating device 4 is installed on the upper surface of the lifting table 31, and the roller rotating device 4 is used to support the flat head cover and rotate it.

[0025] like Figure 2 As shown, specifically, the roller rotation device 4 includes two groups of rollers 41 arranged opposite to each other, one group of rollers 41 is provided with a connecting shaft 42 in front and is driven to rotate by a driving device 43, this group of rollers 41 is an active roller, and the other group is a driven roller. When the flat head cover is placed on the roller, the driving device 43 drives the active roller to rotate, and the active roller brings a rotational force to the flat head cover, and the rotation of the flat head cover drives the driven roller to rotate, thereby adjusting the center position of the flat head cover so that it is on a horizontal line with the center position of the roller.

[0026] The driving device 43 may be a hydraulic motor or a sprocket motor, preferably a sprocket motor.

[0027] like Figure 4 As shown, a pair of disassembly tooling brackets 10 are relatively arranged on the upper surface of the lifting platform 31. The disassembly tooling brackets 10 are located on both sides of the roller rotating device 4. A plug hole 101 is arranged at the end of the disassembly tooling bracket 10, and the plug 102 passes through the plug hole 101. Two or more plug holes 101 can be arranged on each disassembly tooling bracket 10. A limit through hole 1021 is arranged on the pin shaft of the plug 102. When the plug 102 passes through the plug hole 101, the limit block 1022 passes through the limit through hole 1021 to prevent the plug from falling. Therefore, the length of the limit block 1022 is greater than the width of the plug 102. A fastening bolt 1023 is arranged at the end of the plug 102. When the plug 102 holds the flat head cover, tightening the bolt 1023 can fix the plug 102.

[0028] The function of the disassembly tool support 10 is to prevent the flat head cover from falling off during operation and causing safety accidents. At the same time, the existence of the latch plays a role in fixing the flat head cover.

[0029] like Figure 3 As shown, the trolley driving assembly includes a fixed cover plate 7, a movable cover plate 8 and a movable cover plate track 9. The movable cover plate 8 is located at the lower side of the fixed cover plate 7, and rolls on the movable cover plate track 9 through rollers. The disassembly trolley 2 is located at the end of the movable cover plate 8, and is fixedly connected to the movable cover plate 8. The movable cover plate 8 moves in the same direction as the disassembly trolley 2. The purpose of this design is that when the trolley moves toward the supporting workbench, a concave space will be formed between the trolley and the fixed cover plate. If the space is not blocked, the operator will be in danger during the operation. The movable cover plate moves with the trolley to block the concave space, thus eliminating this danger.

[0030] A similar design is to set a front cover plate 13 between the disassembly and assembly trolley 2 and the supporting workbench 1. The front cover plate 13 is specifically set at the upper end of the end point of the trolley movement track, and the height is the same as the height of the fixed cover plate 7. This design seals the space between the end point of the disassembly and assembly trolley movement and the supporting workbench to prevent foreign objects from falling and operating risks.

[0031] like Figure 3 As shown, the trolley driving assembly also includes a trolley motion track 5 and a hydraulic cylinder 6 located on one side of the trolley motion track 5, and the disassembly trolley is pushed to move on the track by the hydraulic cylinder 6. Preferably, the trolley motion track 5 is an anti-rollover track, and a hydraulic cylinder support 61 is provided between the hydraulic cylinder 6 and the trolley motion track 5, so that the equipment can run more stably.

[0032] When removing the flat head cover, hang the roll (with bearing seat) to be removed on the V-shaped bracket supporting the workbench. Then use the flat head cover heating device to heat the flat head cover. When the flat head cover reaches the retreat temperature, the disassembly and assembly trolley quickly moves to the bottom of the flat head cover, the disassembly and assembly trolley lifting assembly rises, and the roller stops after contacting the bottom of the flat head cover. After the disassembly tool bracket on the disassembly and assembly trolley buckles the flat head, the disassembly and assembly trolley moves horizontally to separate the flat head cover from the roll.

[0033] When installing the flat head cover, hang the smooth roller on the V-shaped bracket of the flat head cover disassembly and assembly machine's support workbench, and hang the heated flat head cover on the roller of the disassembly and assembly trolley. The disassembly and assembly trolley runs to the roller, and after the axial alignment of the flat head cover and the roller is completed through the lifting and lowering of the trolley lifting assembly and the rotation of the roller, the disassembly and assembly trolley moves horizontally to assemble the flat head cover to the roller.

[0034] The embodiments disclosed in the present utility model are preferred embodiments, but are not limited thereto. Ordinary technicians in this field can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present utility model, they are all within the protection scope of the present utility model.
