Problems solved by technology

Now, in the final overall processing of the coiler, due to the processing equipment, means and manufacturing process, the coiler can only ensure that the expanded state is a true circle in the final processing, and the helix cannot be obtained by a simple method. , even if it can be processed into a helix, it can only be a pitch, which cannot meet the coiling needs of strip steel with different thicknesses
In order to eliminate the folding of the cold-rolled strip coiling jaws, the existing method is to make some improvements to the coils of the individual coilers, but the shape is still based on a true circle, with only a part of the transition section, and the length is not enough At the same time, due to the limitation of the structure, it cannot be used for large tension coiling. This kind of reel can only reduce the number of folds and ease the degree of folds, but cannot be fundamentally solved, which affects the quality of steel coils, especially stainless steel coils. quality

Embodiment 1

[0038] The coiler used in this embodiment is the coiler produced by SUNDWIG, Germany. The diameter of the reel 11 when it is expanded is Ф610mm, the circumference is 1916mm, and the width is 1400mm. The strip steel 9 coiled is OCr18Ni9 stainless steel, and the thickness is 3mm .

[0039]Referring to Fig. 2 for the coiling step of the present embodiment, the insertion end 13 of the strip steel 9 is pulled out from the guide roller 8 of the rolling mill, inserted into the jaw 12 of the reel 11, and then the elastic pad 10 is laid on the guide roller 8 and the clamp. On the strip steel 9 between the openings 12, the thin end 14 of the elastic pad 10 is next to the jaw 12, and the thick end 15 of the elastic pad 10 is on the top. In the present embodiment, the thick end 15 is close to the guide roller 8, and then starts The reel 11 of the coiler makes the reel 11 rotate counterclockwise to coil the steel strip 9, and forms an elastic lift 16 on the right side of the jaw 12 in Fig....

Embodiment 2

[0042] The coiler used in this embodiment is the coiler produced by Spain FAGOR. The diameter of the reel 11 when it is expanded is Ф610mm, the circumference is 1916mm, and the width is 1400mm. The strip steel 9 coiled is 430 stainless steel and the thickness is 2.0mm. mm.

[0043] Referring to Fig. 4 for the coiling step of this embodiment, the insertion end 13 of the strip steel 9 is pulled out from the guide roller 8, inserted into the jaw 12 of the reel 11, and then the elastic pad 25 is laid on the guide roller 8 and the jaw 12 On the strip steel 9 between, the thin end 27 of elastic liner 25 is down, is 470mm apart from jaw 12, and the thick end 26 of elastic liner 25 is on, then starts the reel 11 of coiler, makes reel 11 Rotate counterclockwise to coil the steel strip 9, (you can also start the reel 11 of the coiler to make the reel 11 rotate 90° and then pad the elastic liner 25) and form an elastic warp on the right side of the jaw 12 in Fig. 5 Start 28, when reel 1...

Embodiment 3

[0046] The coiler used in this embodiment is a coiler produced by SUNDWIG, Germany. The diameter of the reel 11 when it is expanded is Ф610mm, the circumference is 1916mm, and the width is 1400mm. The strip steel 9 coiled is OCr18Ni9 stainless steel with a thickness of 1.5 mm.

[0047] The coiling step of the present embodiment can refer to Fig. 4, and the insertion end 13 of strip steel 9 is pulled out from guide roller 8, is inserted into the jaw 12 of reel 11, and then elastic liner 25 is laid on guide roller 8 and jaw On the strip steel 9 between 12, the thin end 27 of elastic liner 25 is down, be 400mm apart from jaw 12, the thick end 26 of elastic liner 25 is on, start the reel 11 of coiler then, make reel 11 anticlockwise rotation coiling strip steel 9, and form elastic upturn 28 on the right side of jaw 12 among Fig. 6, while reel 11 coils strip steel 9, elastic liner 25 is also rolled into circle, Roll between the fan-shaped plate outer surface 17 of the reel 11 and ...

Abstract

A method for eliminating crease generated by the winding jaw from the cold-rolled steel band includes such steps as inserting one end of said steel band in the jaw of reel, arranging an elastic pad with one thick end and one thin end on the surface of steel band between guide roller and jaw, or sticking it on the reel, and winding the steel band.

Description

technical field [0001] The invention relates to a method for eliminating the fold marks of the coiling jaws of cold-rolled strip steel. Background technique [0002] In the production of cold-rolled strip steel, uncoiling and coiling are required in each unit. The side of the reel 1 of the existing cold-rolled strip coiler is a cylindrical surface, and its cross section is a true circle 5. When the strip steel is coiled Insert one end of the strip steel, that is, the insertion end 3 of the cold-rolled strip steel coil, into the jaw 2 of the coiler 1 of the cold-rolled strip steel coiler. Because the strip steel has a certain elasticity, the strip steel elastically warps outside the jaw 2 4 forms a transverse arc-shaped boss, see Fig. 1, in addition the coiler is a true circle 5 in the coiling state, and the strip steel is a helical line 7 when coiling, and the two curves are inconsistent. During coiling, when the strip steel rolls to the jaw, the thickness of the strip stee...
