DETAILED DESCRIPTION

[0024] The use method of the utility model will be further explained in combination with the drawings and specific embodiments.

[0025] As Figures 1 to 5 shown, a small stand roll lubricating device before shearing, including the front side guide plate before shearing 1, the plate blank conveying roller 2, the mounting frame 3, the small stand roll 4 and the pressing plate 5, two the front side guide plate before shearing 1 mutually symmetrical parallel arrangement, and multiple the plate blank conveying roller 2 mutually parallel arrangement between two the front side guide plate before shearing 1, multiple the mounting frame 3 is located the front side guide plate before shearing 1, and the small stand roll 4 is equipped in the mounting frame 3, the small stand roll 4 top is equipped with the pressing plate 5;

[0026] Still include lubricating mechanism 6, the lubricating mechanism 6 with small stand roll 4 synchronous rotation, through lubricating mechanism 6 in rotation for small stand roll 4 supplies oil lubrication.

[0027] The lubricating mechanism 6 includes rotating disc 61, sealing plate 62, connecting rod 63, compression spring 64, cylindrical block 65 and oil pipe 66;The rotating disc 61 is located in the pressing plate 5, the rotating disc 61 center is provided with circular hole 611, the rotating disc 61 bottom and the small stand roll 4 top are connected, the rotating disc 61 is provided with mutually symmetrical cavity 612, through hole 613 and circular groove 614 on any diameter through the center in sequence respectively, and the cavity 612, through hole 613 and circular groove 614 on both sides of the center are communicated, the inner wall of circular hole 611 and two the cavity 612 are through;

[0028] The cavity 612 is equipped with sealing plate 62, the sealing plate 62 is equipped with connecting rod 63, and the connecting rod 63 passes through the through hole 613, one end of the connecting rod 63 is connected with the sealing plate 62, and the other end is connected with the cylindrical block 65, the cylindrical block 65 is located in the circular groove 614, the compression spring 64 is sleeved on the connecting rod 63, and the compression spring 64 is located in the cavity 612, the circular hole 611 on the top of the rotating disc 61 is equipped with oil pipe 66.

[0029] It should be noted that the cylindrical block 65 is a counterweight. During the rotation of the turntable 61, the centrifugal force generated will also increase. There is a gap between the cylindrical block 65 and the circular groove 614. At the same time, air holes are also provided on the circular groove 614 to ensure that the internal gas can be discharged during the process of the cylindrical block 65 moving outward under centrifugal force, so as to ensure the normal movement of the cylindrical block 65 and thus realize the opening and closing of the sealing plate 62.

[0030] The two sealing plates 62 have a semi-circular structure, and sealing rubber is provided on the diametrical side of each of the two sealing plates 62. The two sealing plates 62 cooperate with each other to seal the circular hole 611 on the turntable 61. As the centrifugal force increases, the sealing plates 62 are opened, lubricating oil is added into the small vertical roller 4, and the small vertical roller 4 is lubricated. The lubricating oil is blocked from the outside by the contact of the sealing rubber on both sides.

[0031] The small vertical roller 4 has a rotating shaft 41 at both ends, and an oil inlet hole 42 is opened at the center of the rotating shaft 41 at either end. The oil inlet hole 42 is connected to the circular hole 611.

[0032] During rotation, the small vertical roller 4 will drive the turntable 61 to rotate, while the shafts 41 at both ends of the small vertical roller 4 will not rotate. Lubricating oil enters the interior of the small vertical roller 4 through the oil inlet holes 42 on the shafts 41 and lubricates the interior of the small vertical roller 4, thus achieving automatic lubrication of the small vertical roller 4 and preventing jamming.

[0033] The pressure plate 5 is connected to the mounting frame 3 by bolts 7. Installing the pressure plate 5 onto the mounting frame 3 with bolts 7 facilitates disassembly and maintenance during subsequent use.

[0034] The free end of the oil pipe 66 is connected to the oil pump. The oil pump is used to supply oil to the oil pipe 66. It should be noted that the oil pump will only start when the small vertical roller 4 is working, and the oil pump will always be filled with lubricating oil. As the centrifugal force increases, the sealing plate 62 opens, and the lubricating oil will enter the interior of the small vertical roller 4. Furthermore, the oil pump replenishes oil periodically, replenishing oil 3 times every hour when the small vertical roller 4 is working, 3 ml each time, to avoid the continuous entry of lubricating oil into the interior of the small vertical roller 4 while it is working.

[0035] Working process: when the guide plate enters between the two sides of the shearing front side guide plate 1, the guide plate will contact with the slab conveying roller 2 and move forward, so that the slab conveying roller 2 rotates, when the guide plate moves forward, the side of the guide plate will contact with the small vertical roller 4 and drive the small vertical roller 4 to rotate, when the small vertical roller rotates, the rotating disc 61 rotates, the cylindrical block 65 will slide in the circular groove 614 and drive the connecting rod 63 and the sealing plate 62 to move radially outward, at the same time, the compression spring 64 will be compressed, so that the round hole 611 is opened, the lubricating liquid in the oil pipe 66 will flow into the oil inlet hole 42 in the rotating shaft 41 through the round hole 611, so as to lubricate the small vertical roller 4.

[0036] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the embodiment, for the skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of the technical features, but any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
