Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling, in particular to a combined cold rolling roller frame. Background Art

[0002] Rollers are very important production tools in the cold rolling industry. The quality of their roll surfaces determines to a certain extent the quality of cold rolled products, such as automotive sheets, home appliance sheets, color-coated sheets, and electro-galvanized sheets.

[0003] Publication (Announcement) No.: CN219599426U discloses a roller stand. The roller stand includes two mounting mechanisms arranged opposite to each other, the mounting mechanisms include a bracket and a support unit for supporting the roller head, so that the two corresponding support units on the two mounting mechanisms are respectively used to support the roller heads at both ends of the roller, and the support unit includes two rollers rotatably arranged on the bracket, the roller head can be placed between two rolling assemblies, the roller is provided with a protrusion extending from the top of the bracket, and the roller head can be supported by rolling between the protrusions of the two rollers. Therefore, when the surface of the roller is inspected, the roller can be driven to rotate by rolling the roller, so that the surface quality of the roller can be inspected 360° without dead angles, which greatly reduces the occurrence of missed inspection of roller surface defects and ensures the roller surface quality of the roller.

[0004] Although the above scheme has the advantage of reducing the occurrence of missed detection of roller surface defects, it is inconvenient to regularly provide the roller with an appropriate amount of lubricant when the roller head of the roller is worn due to long-term contact and friction with the rolling assembly. Moreover, the above scheme only places the roller between two sets of rolling assemblies, and no limiting mechanism is set to limit the roller. The roller is prone to shaking during rotation. For this reason, we propose a combined cold rolling roller stand. Utility Model Content

[0005] The main purpose of the utility model is to provide a combined cold rolling roller frame, which solves the problem of inconvenience in regularly providing the roller with an appropriate amount of lubricant when the roller head of the roller is worn out due to long-term contact and friction with the rolling assembly through a maintenance mechanism, and solves the problem of the roller being easily shaken during rotation when the roller is placed between two groups of rolling assemblies and a limiting mechanism is not provided to limit the roller.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A combined cold rolling roll stand comprises a support, a rolling assembly arranged on the top of the support, a rolling roll arranged between two adjacent groups of rolling assemblies, and further comprises:

[0008] A maintenance mechanism, wherein the maintenance mechanism is arranged on the top of the bracket;

[0009] The maintenance mechanism includes a fixing frame installed on the top of the bracket, a sliding unit arranged inside the fixing frame, and a lubrication unit arranged at the bottom of the sliding unit;

[0010] A limiting mechanism, wherein the limiting mechanism is arranged on the side of the roller;

[0011] The limiting mechanism comprises a positioning unit arranged at the end of the roller and a pushing member arranged at the side of the positioning unit.

[0012] Preferably, there are multiple rollers, and the multiple rollers are equidistantly distributed on the top of the bracket.

[0013] Preferably, the sliding unit comprises a screw rod movably arranged on the inner top surface of the fixing frame, and a sliding sleeve threadedly connected to the outer circumference of the screw rod, and a driving member is arranged at one end of the screw rod.

[0014] Preferably, the lubrication unit comprises a box body installed at the bottom of the sliding sleeve, an extraction member arranged at the bottom of the inner side of the box body, and an oil outlet pipe installed at the bottom of the box body.

[0015] Preferably, an oil inlet is provided at the top of the side wall of the box body, an oil inlet pipe is installed at the oil inlet, and a sealing plug is threadedly connected to the end of the oil inlet pipe.

[0016] Preferably, a limiting groove is provided at the end of the roller;

[0017] The positioning unit includes a limiting block arranged inside the limiting groove, a movable cylinder installed outside the limiting block, one end of a connecting rod movably connected to the outer surface of the movable cylinder, and a fixing plate installed at the other end of the connecting rod.

[0018] Preferably, there are two pushing members, and the two pushing members are arranged oppositely between the fixing plate and the bracket.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. In the utility model, the maintenance mechanism is provided to cooperate with the output shaft end of the driving member to drive the screw to rotate, so that the sleeve slides along the length direction of the screw under the action of the threaded pair. When the sleeve slides, it drives the box to move, so that the oil outlet pipe is displaced to just above the joint between the roller and the rolling assembly. The extraction member works to discharge the lubricating fluid in the box through the oil outlet pipe and drips on the joint between the roller and the rolling assembly, which is convenient for regularly providing an appropriate amount of lubricant to the roller, thereby reducing the wear of the roller and the rolling assembly.

[0021] 2. In the utility model, a limiting mechanism is provided, which cooperates with the output shaft of the pushing member to drive the fixed plate to move toward one side of the bracket, so that the connecting rod pushes the movable cylinder to move toward the side close to the rolling roller, so that the limiting block is engaged with the limiting groove, thereby limiting the two ends of the rolling roller to prevent it from shaking during operation.
