And a small edge forming stage: passing the groove through each small edge forming roller set, utilizing the edge folding roller and the edge folding idler wheel to be matched with the two sides of the rolled groove up and down, and finally obtaining the cap-shaped steel with small edges on the two side walls of the groove by downward pressing; in the small edge forming process, the elevator is controlled to control the synchronous plate to move on the slide rail, the fixed seat is driven to move, and the positions of the folding roller wheel and the folding idler wheel are adjusted to realize the small edge forming with different waist heights;

and (3) a shearing stage: passing the cap-shaped steel through a shearing mechanism, utilizing a fixed cutter group to combine the cap-shaped steel, enabling the cap-shaped steel to pass through a conveying port, and cutting off by a lower cutter of a shearing cutter to obtain formed cap-shaped steel; in the shearing stage, the left fixed knife and the right fixed knife of the fixed knife group move on the shearing frame to adjust the distance between the left fixed knife and the right fixed knife to be matched with the cap-shaped steel.

Each forming roller set and waist height forming roller set in the section groove forming stage are sequentially arranged along the steel conveying direction, the two side rolling wheels comprise two upper forming rollers, two lower forming rollers, two upper waist rollers and two lower waist rollers which gradually shrink along the interval of the conveying direction assembly, two side walls of the steel are inwards rolled to form a groove through the two lower forming rollers and the two waist height idler wheels, two side walls of the groove are sequentially changed from an inner eight shape to a vertical parallel shape or an outer eight shape under the rolling of the two lower forming rollers and the two waist height idler wheels, and finally a section groove with two parallel side walls is obtained.

And in the small edge forming stage, small edge forming roller sets are arranged on two sides along the conveying direction, the forming profiles of the edge folding rollers and the edge folding idler wheels on the two sides on the portal frame gradually increase towards the outer sides of the two side walls of the groove, and the two side walls sequentially change from an outer eight shape to a horizontal parallel/inner eight shape to obtain the cap-shaped steel.

And in the shearing stage, the fixed cutter group adjusts the position of the left fixed cutter on the left guide rail through the left adjusting plate, the right adjusting plate adjusts the position of the right fixed cutter on the right guide rail, the left fixed cutter and the right fixed cutter are matched with the cap-shaped steel passing through the conveying port of the shearing frame, and the shearing cutter shears the profile steel to finally obtain the formed cap-shaped steel.

According to the cap-shaped steel forming process provided by the embodiment, the tapered roller sets are used for extruding the groove with the two side walls parallel to each other, the tapered small edge forming roller sets are used for setting the rolling height according to production requirements, and when cap-shaped steel with various sizes is produced, the bottom width, the waist height and the width of the small edge of the cap-shaped steel are adjusted in a stepless mode according to actual requirements, so that the production efficiency is improved.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
