Abstract

The invention relates to a roll centre heating type roll bending forming method of a metal plate strip, which belongs to the field of roll bending forming technologies and equipment and is used for solving the problem of difficult forming of sheet metals, such as magnesium alloy, aluminum alloy, high tension steel, and the like due to work hardening. The roll centre heating type roll bending forming method is characterized by comprising the following steps of: heating a working roll in a protective atmosphere; carrying out roll bending forming on the sheet metal by the hot working roll after the working roll is heated to required temperature; transferring heat to the sheet metal from the working roll; heating the sheet metal; cooling the sheet metal subjected to the roll bending forming; and cutting according to a set length. Furthermore, the invention also provides a roll centre heating type roll bending forming device according to the method. The device comprises a roll bending forming machine, a computer system, a heating system, a cooling system and a gas protective cover. Compared with the traditional roll bending forming device, the invention has the advantages of less forming times and high surface quality of a product; and the sheet metal which is difficultly formed is processed more easily.

Description

technical field

[0001] The invention relates to a roll center heating type roll bending forming method and device for metal plates, which belongs to the field of roll forming technology and equipment, and is used to solve the problem of difficult forming of metal plates such as magnesium alloy, aluminum alloy and high-strength steel due to work hardening The problem. Background technique

[0002] Roll forming is to gradually bend metal strips such as coils and strips transversely through sequentially arranged multi-pass forming rolls to make profiles with specific cross-sections. Roll-bending profiles have the characteristics of reasonable section, high strength, high rigidity, light weight, and high metal utilization rate. They are economical section profiles with a wide range of uses, and are widely used in automobiles, construction, machinery, aviation and other industries.

[0003] At present, my country's national economy continues to develop rapidly, the market demand...
