Cold-formed sectional steel rolling machine for skew roller

Abstract

The invention discloses a cold-formed sectional steel rolling machine for a skew roller. The cold-formed sectional steel rolling machine for the skew roller comprises an engine base and a frame arranged on the engine base, wherein an upper roller, a lower roller and a vertical roller are arranged on the frame, the upper roller is a skew roller in a shape of a round cake, after an axis of the skew roller is inclined relative to an axis of a lower roller shaft, the skew roller is arranged on the frame, the vertical roller is arranged in a translation movable frame window arranged at the inner side of the frame and a roller surface is a conical slope, and the angle gamma of the slope is equal to 45-76 degrees. According to the cold-formed sectional steel rolling machine for the skew roller provided by the invention, after the axis of the skew roller is inclined relative to the axis of the lower roller shaft, the skew roller is arranged on the frame, so that a surface of the skew roller and the conical slope of the vertical roller form a certain inclined angle so that a cold-formed sectional steel rolling part is formed, thus the radius size and the shape of a bending round angle of a section steel product are controlled, and the quality of the product is effectively improved.

Description

technical field [0001] The invention relates to metal cold-bending forming processing equipment, in particular to a cold-bending section steel rolling mill with skewed rolls. Background technique [0002] With the wide application of cold-formed products, people have higher and higher requirements on the shape and quality of cold-formed products. Most of the commonly used cold bending mills are flat roll mills or universal rolling mills with side vertical rolls, and their roll axes are either horizontal or vertical. When the cold-bending mill forms the rounded corners of square rectangular tubes or sharp-edged square rectangular tubes, the rounded corners are obtained by extruding strip steel with flat rolls and vertical rolls. The size and shape of the rounded corners are difficult to control, which directly affects the product. quality, increased production costs, and brought greater economic losses to the enterprise. For this reason, it has been proposed to use the tech...

Problems solved by technology

Although this patent belongs to pressure processing, the rolls are placed obliquely in the rolling mill, which can change the finished radius of the rolled piece, but the structure of the invention is complicated, the roll is conical, and the roll surface contacts the outer surface of the circular rolled piece, and it is mainly used in The hot rolling of seam steel pipes, and the cross-sectional area of ​​the rolled pieces decreases continuously during the rolling process, and the length of the rolled pieces increases continuously, so this patent is essentially different from the skewed rolls produced by cold-formed steel
