The pickling line equipment is provided with a phosphorus breaking machine, a leveling machine and a tension leveler, and the equipment has the effect of leveling and improving the plate shape of the medium-thickness plate high-strength steel. However, because the thickness and the strength of the medium plate strip steel are high, the ideal requirements on the strip steel head and the strip tail cannot be met, particularly, after the outlet of the production line cuts and shears, the cutting position is subjected to great downward shearing stress (the head of the front strip steel and the tail of the rear strip steel), and the head of the front strip and the tail of the rear strip are subjected to downward shearing force due to the fact that tension connection is lost, so that the situation that the strip head and the tail are upturned occurs.

The utility model is positioned at the outlet of an acid washing production line, and relates to a device for preventing coiling of a tail ring of a medium-thickness plate high-strength steel, which is macroscopically arranged as shown in figure 1 and comprises a tension straightening roller set 1, a slitting shear 4, a steering roller set 6 and a scroll 7. In this embodiment, a pinch roll 3 is further included between the tension straightening roll set 1 and the slitting shear 4, and an oiling machine 2 is further included between the tension straightening roll set 1 and the pinch roll 3. The steering roller group 6 and the scroll 7 are two groups.

The tension straightening roller set 1 establishes tension to ensure the running of strip steel; the oiling machine 2 is used for oiling the surface of the strip steel and preventing rust; the pinch roll 3 ensures the strip steel stability in the strip steel slitting process and prevents the strip steel from slipping; the slitting shears 4 are used for slitting and shearing the continuous strip steel; the steering roller set 6 comprises a steering roller and a compression roller, and when the strip steel passes through the winding shaft, the strip steel is ensured to enter the winding shaft for winding; the reel 7 winds the strip steel 5.

The tension straightening roller set 1 is used for forming tension with the winding shaft 7 of the winding unit, and as shown in fig. 2, the tension straightening roller set 1 comprises a No. I compression roller 16, a No. I tension roller 15, a No. II compression roller 12, a No. II tension roller 14, a straightening roller 13 and a hydraulic cylinder 17 which are arranged on a roller frame.

In this embodiment, the diameters phi 1250, 16 and 270 of the

tension rollers

15 and 14 and the

tension rollers

16 and 12 are described. The specific construction and control of the press roller and the pressing device are prior art and will not be described in detail here.

The I-size press roll 16 is positioned in front of the II-size tension roll 14. The strip steel 5 walks in the tension straightening roller set 1 in an inverse S shape, and specifically enters the upper part of the straightening roller 13 from the position between the No. II compression roller 12 and the No. II tension roller 14 through the position between the No. I compression roller 16 and the No. I tension roller 15, and around the No. I tension roller 15 and the No. II tension roller 14.

In normal production, the I-type press roll 16 and the II-type press roll 12 are in a lifting state, the outlet strip steel 5 runs for 40min/m before the slitting shear 4 is required to slit, and after a pressing device of the I-type press roll 16 and the II-type press roll 12 receives a pressing signal, the pressing device presses down for about 2 seconds; the purpose of the two pressing roller pressing operation is to prevent the strip steel 5 from being fixed after the strip steel is cut by the flying shears, and prevent the strip steel from sliding backwards.

The straightening roller 13 is positioned at the front lower part of the II-type tension roller 14. The hydraulic cylinder 17 is used for lifting the straightening roller 13, the hydraulic cylinder 17 can be directly connected with two ends of the straightening roller 13, or can be realized through the leverage of the connecting frame 11 in the embodiment, specifically, the middle section of the connecting frame 11 is hinged with the roller frame, the front end is used for jacking the straightening roller 13, and the rear end is connected with the lower end of the telescopic rod of the hydraulic cylinder 17.

Between the turning roll 64 and the reel 7 is a guide table 68.

The rear press roller 62 is arranged above the turning roller 64, and the pressing contact between the rear press roller 62 and the turning roller 64 is realized by a rear pressing assembly. In this embodiment, the rear pressing assembly includes a rear hydraulic rod 63 and a rear pressing beam 61, the lower end of the rear hydraulic rod 63 and the front end of the rear pressing beam 61 are respectively hinged to the steering roller frame, and the upper end of the rear hydraulic rod 63 and the rear end of the rear pressing beam 61 are hinged.

The front pressing beam 65 is used to press the front pressing roller 66 against the steering roller 64.

When the slitting scissors 4 cut the rolls, the tail of the previous roll is thrown under the action of no tension. The front press roller 66 is used when the strip steel 5 is worn, and is used for pulling the strip head to the reel 7 for coiling through the strip threading guide plate 68, and the tail is not thrown. When the production thickness is more than or equal to 4.0mm, an operator selects to throw the front press roller 66, the rear press roller 62 and the front press roller 66 are started to press down simultaneously when the strip steel of the coiling machine is thrown, and the tail strip steel 5 has a downward buckling trend when the strip steel is thrown, so that the tail strip steel can be attached to a steel coil after coiling. And the pressure of the back pressure roller 62 is optimized, the pressure is adjusted from 90MPa to 110MPa, and when the thickness of the strip steel is less than 4.0mm, the front pressure roller 66 is not used.
