Description

Technical Field

[0001] The utility model relates to the technical field of leveling machines used for metal plate processing, in particular to a novel support roller installation structure. Background Art

[0002] Leveling machine is a commonly used equipment for leveling metal plates, which usually includes an upper row of working rollers and a lower row of working rollers. The plate to be leveled can pass between the upper and lower rows of working rollers and complete the leveling operation under the squeezing action of the upper and lower working rollers. Usually, the working rollers are of a relatively long length. In order to prevent the working rollers from bending and deforming when the plate is leveled, thereby affecting the leveling of the plate, support rollers are usually arranged above the upper working roller and below the lower working roller to improve the deformation resistance of the upper and lower working rollers. The existing installation of support rollers usually involves multiple support rollers being installed in parallel on the same fixed seat, which makes the maintenance and replacement of support rollers inconvenient and requires the support roller group to be removed as a whole. On the other hand, the whole-root setting of the support rollers has poor deformation resistance and has limitations on the supporting effect of the working rollers. Once the support rollers themselves are bent and deformed, the entire support roller needs to be replaced, increasing the replacement cost. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a novel support roller installation structure.

[0004] The technical solution of this utility model is as follows:

[0005] A novel support roller installation structure is used for supporting the working rollers of a leveling machine, the working rollers comprising an upper working roller and a lower working roller. As the core technical concept of the utility model, the above-mentioned support roller installation structure comprises an upper support group and a lower support group respectively arranged above the upper working roller and below the lower working roller. Specifically, the upper support group and the lower support group each comprise a plurality of support members arranged in a linear manner, the support members comprising two fixed seats arranged in a gap and connected to the frame of the leveling machine, a support roller member which is rotatably provided between the two fixed seats and is pressed against the working roller. This arrangement enables damaged support members to be disassembled separately when the support members are repaired or replaced, significantly reducing the difficulty of maintenance and replacement and reducing the replacement cost. At the same time, the manner in which multiple support members are arranged in a linear manner to complete the working roller support work increases the deformation resistance of a single support roller member, so that the support effect of the support members on the working rollers can be more effective.

[0006] In the novel support roller installation structure as described above, the upper support group and the upper working roller are arranged relative to each other up and down, so that the upper working roller can have a better downward pressing ability, thereby ensuring the leveling effect of the upper working roller on the plate.

[0007] Furthermore, the lower support group is provided with several groups, and a lower working roller is supported above any two adjacent lower support groups to cooperate with the upper working roller to complete the leveling of the plate, so that the support parts of the lower support group can provide the lower working roller with a supporting force perpendicular to its axial direction, thereby ensuring that the lower working roller can better support the plate, and thus the leveling machine can better complete the leveling of the plate.

[0008] A novel support roller installation structure as described above, the support roller member includes a rotating shaft and a roller, the roller is rotatably arranged on the outer ring of the rotating shaft through a bearing, and is tightly pressed against the working roller. The support roller member is arranged in a split type, so that when any part of the roller, the rotating shaft, and the bearing is damaged, they can be replaced separately, and at the same time, the operation of the roller along with the working roller can be smoother.

[0009] As a preferred embodiment, bearings are provided at both ends of the roller to improve the pressure bearing capacity of the roller and thereby ensure its supporting effect on the working roller.

[0010] As a further preference, the outer diameter of the upper support group rollers is smaller than the outer diameter of the lower support group rollers, so as to ensure the supporting effect on the lower working rollers, thereby ensuring the overall leveling effect of the leveling machine.

[0011] More preferably, the length of the upper support group rollers is smaller than the length of the lower support group rollers, which further ensures the supporting effect of the lower support rollers on the lower working rollers.

[0012] A novel support roller installation structure as described above, wherein the fixed seat includes a fixed block connected to the frame, and a clamping block detachably connected to the fixed block, and the end of the rotating shaft is fixed between the fixed block and the clamping block. Only by removing the clamping block, the disassembly and repair of the support roller can be completed, thereby further ensuring the convenience of the disassembly and repair of the support roller.

[0013] In order to ensure the service life of the bearing, sealing covers are provided at both ends of the roller.

[0014] In order to further ensure the supporting effect of the supporting member on the working roll, the rotating shaft and the roller are both made of steel.

[0015] The beneficial effects of the utility model are as follows: the utility model is a new type of support roller installation structure, the upper support group and the lower support group both include a plurality of support members arranged linearly, so that when the support members are repaired or replaced, the damaged support members can be disassembled separately, which significantly reduces the difficulty of inspection and replacement, and reduces the replacement cost. At the same time, the plurality of support members are arranged linearly to complete the working roller support work, which increases the deformation resistance of a single support roller member, so that the support effect of the support members on the working roller can be more effective.
