Patent publication number CN211965376U discloses a roller cold rolling mill, including a workbench, support plates are vertically installed on both sides of the upper surface of the workbench, two cold rolling rolls are installed between the support plates, and the cold rolling rolls are horizontally arranged. Two brackets are symmetrically installed at one end of the upper surface of the workbench, and a fixing bolt is vertically installed on the top of the bracket. A nut is screwed on the end of the fixing bolt, and a sleeve is vertically sleeved on the fixing bolt. A bearing is installed on one side of the sleeve through a connecting rod, and a rotating shaft is horizontally installed in the bearing. The end of the rotating shaft is connected to a guide wheel through a positioning structure, and a C-shaped frame is installed on the top of the fixing bolt. A screw hole is vertically opened at one end of the top of the C-shaped frame, and a threaded rod is vertically screwed in the screw hole. During the cold rolling process, the copper strip can enter between the cold rolling rolls along the guide wheel for processing to prevent the copper strip from deflecting and tilting during processing.

[0019] In the above embodiment, it should be noted that the left and right ends of the oil tank 401 can be installed just inside the installation frame 205, so as to ensure that the oil tank 401 is suspended and fixed.

[0020] The technical effect achieved by the above embodiment is: when the guide groove 203 is utilized, the oil body can enter the interior of the rotating groove 202, and is driven by gravity and rotation to enter the interior of the rotating groove 202 below, thereby completing the lubrication operation of the four rotating grooves 202 in sequence. There is no need for staff to perform individual lubrication operations, thereby improving the lubrication efficiency, thereby ensuring normal rotation and ensuring the support efficiency of the corresponding support parts. Example 2

[0021] like Figure 1 and Figure 4As shown, a side support device for a cold rolling mill working roll includes all the contents of Example 1. In addition, the pushing device 5 includes a central axis rod 501, and studs 502 are fixedly installed on both ends of the central axis rod 501. The thread directions of the two studs 502 are set to be opposite. The ends of the studs 502 are fixedly installed with limit blocks, and the limit blocks are rotatably installed inside the limit groove 208. One end of the stud 502 is fixedly installed with a rotating rod 505, and a push plate 503 is threadedly installed on the surface of the stud 502.

The sealing plate 504 is movably sleeved inside the square groove 207, and its size is adapted to the size of the long groove 402.

[0022] The technical effect achieved by the above embodiment is: the size of the sealing plate 504 and the size of the long groove 402 are matched to ensure that the push plate 503 seals the top of the oil tank 401 when moving, preventing the oil from seeping out from the top, and the user can judge whether the oil inside the oil tank 401 needs to be refilled based on the extended length of the sealing plate 504, thereby achieving a prompt effect, and the shielding plate 406 can be used to protect the top of the working roller 3.

[0023] Working principle: When the interior of the rotating groove 202 needs to be lubricated, the rotating rod 505 is rotated to drive the stud 502 to rotate, and the push plate 503 cooperates to squeeze the oil inside the oil tank 401 into the connecting pipe 404, and then enters the interior of the rotating groove 202 through the connecting groove 405, and then enters the interior of the rotating groove 202 at the bottom through the guide groove 203 to complete the lubrication. When the oil inside the oil tank 401 is insufficient, the rotating rod 505 is rotated to drive the push plate 503 to reset, and then the box cover 403 is opened to inject oil into the interior.
