Roller forming device for steel

The invention relates to a roller forming device for a profiled steel, in particular to an end angle of a steel which is arranged inside a steel roll table for supporting and shaping the steel to prevent deformation of the steel structure.

According to the structural steel, it is an important material that relies heavily on heavy industries such as construction. The common structural steel can be divided into C type, H type, T type, U type and square type, etc., so as to improve production efficiency in response to demand, it is large. Some manufacturers have standardized and standardized the production process through automated machinery.

For the profiled steel with end angle structure, the bending angle often has the problem of unevenness or deviation. Especially for square steel with more curved end angles, the current molding technology is mainly to set a plurality of rollers on the molding machine. In the group, the plate body of the steel plate can be bent and bent through the plurality of roller sets of the molding machine, and the open ends of the bending are butted, and the open ends are joined and fixed by welding, but the joints are horizontally aligned. Therefore, even if it is fixed by welding, the joint may be deformed due to weight or squeezing.

Therefore, in order to strengthen the joint structure, the Republic of China Announcement No. M355975 discloses a "square steel structure" which is formed by forming a right-angled bent edge inward at the two open ends of the square steel, so that the open end can be folded by both sides. While achieving mutual support, the method still needs to perform welding at the joint. However, the welding process and the technical quality are the key factors that directly affect the structural strength of the steel. Therefore, fixing the joint by welding is not only a problem of easy derivation of the welding process. The quality of the steel produced is difficult to control.

In order to solve the problem caused by the welding method fixing the interface end of the metal plate, the metal plate is rolled and bent into a shape of a predetermined shape through a roller of the molding machine, and then the two open ends are fitted to each other and then molded. The roller of the machine is gradually pressed, and the open end is tightly compacted to form a joint state, thereby replacing the welding action and reducing the defect rate caused by the welding process.

However, during the rolling process, the steel plate may be deformed by the forced pinch of the roller or the steel plate during the rolling process, which may cause distortion of the steel plate, especially after the rolling is completed. The deviation of the end angle of the fold causes the deformation of the square steel.

In view of the fact that the end angle of the conventional steel is easy to be deformed during the bending process, especially the way in which the open ends of the steel plates are fitted to each other through the pinch of the roller, it is easier to deform the end angle of the steel by forced application, so there is still improvement. Necessary.

Therefore, the object of the present invention is to ensure that the profile steel is optimally formed by providing a body in the steel roll table and setting a plurality of rolling disk sets on the seat body, thereby strengthening the end angle of the steel in the rolling process. .

Another object of the present invention is to place the guiding block on the seat body, so that the deformed steel during the rolling movement is gradually expanded back to the desired size and shape through the guiding block, and the roll forming of the steel is formed. The process is smoother.

In order to achieve the foregoing, the present invention provides a profiler roll forming device which is disposed inside a steel roll table and includes: a body which is elongated and has a plurality of recesses above the seat body.
