Detailed Description

The invention is further described below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1, the damping device for the tail of the cold-rolled steel strip comprises a frame, a damper 5 and a guide plate 6, wherein the damper 5 comprises a fixed rod 502, a flat roller 504 and a damping spring 503.

The frame consists of a straight section frame 4 and a curved section frame 3, the straight section frame 4 is a box-shaped frame structure (shown in figure 4) consisting of angle steel 401 and flat steel II 402, two groups of guide plates 6 are arranged inside the straight section frame 4, as shown in figure 3, the inner side of each guide plate 6 is respectively provided with a rubber layer 601, each group is provided with two guide plates 6, the sections of the two guide plates 6 form a Y-shaped structure, the outer side of each guide plate 6 is respectively provided with two connecting rods 602, and each connecting rod 602 is welded with the corresponding flat steel II 402; a gap is arranged between the two guide plates 6 in the same group, and the cold-rolled steel strip 2 can pass through the gap between the guide plates 6.

As shown in fig. 2, two sets of dampers 5 are disposed between two sets of guide plates 6, the flat rollers 504 of the two dampers 5 in the same set are disposed opposite to each other, a rubber sleeve 505 is sleeved outside each flat roller 504, fixing holes 506 are respectively disposed at two ends of a central shaft 501 of each flat roller 504, one end of a fixing rod 502 penetrates through the fixing holes 506, is sleeved with a damping spring 503 and is welded with an angle iron 401 at one corresponding side, and the other end is clamped on the central shaft 501 and is movably connected with the central shaft 501.

The curved section frame 3 is a sector ring type frame structure consisting of a short arc plate 301, a long arc plate 302 and flat steel I303, the short arc plate 301 and the long arc plate 302 are respectively made of arc-shaped angle steel, and the curved section frame 3 is directly welded at the lower part of the straight section frame 4; a group of dampers 5 are arranged between the short arc plate 301 and the long arc plate 302, as shown in fig. 2, the flat roller 504 of each damper 5 is arranged along the wide side of the curved section frame 3, a rubber sleeve 505 is sleeved outside each flat roller 504, two ends of the central shaft 501 of each flat roller 504 are respectively provided with a fixing hole 506, one end of a fixing rod 502 penetrates through the fixing hole 506 and then is sleeved with a damping spring 503 and then is welded with the corresponding arc plate into a whole, and the other end of the fixing rod 502 is clamped on the central shaft 501 and is movably connected with the central shaft 501. The cold-rolled steel strip 2 passes through between the two flat rollers 504, and the strip tail of the cold-rolled steel strip 2 is ensured not to be contacted with the rubber sleeves 505 on the two sides, so that impurities on the rubber sleeves 505 are prevented from being adhered to the cold-rolled steel strip 2.
