The roll adjustment mechanism of the strip in-plane bending forming device as claimed in claim 4, characterized in that there is a boss at one end of the shaft sleeve (22) of the tapered roller sliding fixing mechanism (8); the inner diameter of the boss is The inner diameter of the shaft sleeve (22) is the same, and the shape transitions from a circular arc with the same diameter and curvature as the shaft sleeve (22) to a convex edge that is larger than the outer diameter of the shaft sleeve (22) and the side is a hypotenuse, and The slope of the convex edge is the same as the angle of the tapered roller shaft 4, and is used to cooperate with the gap adjuster (9); there is a groove on the circumference of the outer surface of the shaft sleeve (22); a surface of the upper limit block (21) has a cylinder shaped boss, the other surface is a penetrating semicircle, and the axis of the semicircle is perpendicular to the axis of the cylindrical boss; there is a protruding cylinder in the center of the inner cavity of the upper limit block (21), and the diameter of the cylinder is It is equal to the groove on the outer surface circumference of the axle sleeve (22); the lower limit block (23) is the same as the upper limit block (21) in external dimensions, but there is no protruding cylinder in the inner cavity; the upper limit block (21) and the lower limit block The two semicircular surfaces of the block (23) are combined to form an inner hole that cooperates with the axle sleeve (22); the profile of the positioning block (20) is the same as that of the upper block (21) and the lower block (23), and its center There is a through hole with the same inner diameter of the outer diameter of the surface of the limiting block, and there are mounting holes in the periphery; the shape of the spacer (15) is the same as the upper limiting block (21) and the lower limiting block (23), and there are mounting holes in the periphery.

6. An adjustment method of the roll adjustment mechanism of the in-plane bending forming device of the strip as claimed in claim 1, wherein the adjustment process is:

The first working step: adjust the gap adjusting bolt (24) on the gap adjuster (9), so that the gap adjuster (9) is separated from the two tapered roller shafts (4);

The second step: adjust the protrusion of the slider coupling in the slider coupling to adjust the protrusion of the two tapered rollers;

The third working step: adjust the bolt on the wedge angle adjuster (7) to realize the adjustment of the included angle of the two tapered roller shafts (4);

The fourth working step: by adjusting the bolt on the gap adjuster (9), the gap adjuster (9) is contacted with the two tapered roller shafts (4) and the width of the wedge-shaped roll gap formed by the two tapered roller shafts 4 is changed. the
