Embodiment 1

[0026] Adopt the variable cross-section hat-shaped profile roll forming device of the present invention, the section of formed profile is as follows Figure 5 shown. The metal sheet used is 446 ferritic stainless steel with a forming thickness of about 1.5mm. The forming speed can be set to 300mm / s according to the characteristics of the plate material to be processed, and the rolling speed of the roll can be set by the forming speed. After roll forming, the Figure 5 Variable-section hat profiles of the cross-sectional shape shown.

[0027] To sum up, the rolling forming device for variable-section hat-shaped profiles according to the present invention is easy to assemble and debug, and has high production efficiency and low cost for mass production of hat-shaped variable-section profiles.

Abstract

The invention relates to a roll bending forming method and device of a cap-shaped sectional material with a variable cross section, which belongs to the field of roll bending forming technology and equipment, and solves the problem that the cap-shaped sectional material with the variable cross section is difficult to process. The method comprises the following steps: after a metal plate to be processed is rolled and flattened, conveying the metal plate to a variable-cross-section roll bending forming roller group through a plate belt guide device, and then rolling into the required cap-shaped sectional material; conveying the cap-shaped sectional material after being molded outside the roller group through a sectional material guide device; conveying the cap-shaped sectional material to a cutting device, and implementing the follow-up steps, such as blanking and cutting; and conveying the final products outside the production line through a discharge table, and stacking the final products. The process of producing the cap-shaped sectional material on the whole production line does not need to be monitored, the production efficiency is high, and the product quality is convenient to control.

Description

technical field [0001] The invention relates to a roll forming method and device for a hat-shaped profile with variable cross-section, which belongs to the field of roll-forming technology and equipment, and is used to solve the problem that the hat-shaped profile with variable cross-section is difficult to process. Background technique [0002] In recent years, roll forming, as an efficient and advanced sheet metal forming process technology, has developed rapidly. Roll forming uses sequentially arranged multi-pass forming rolls to continuously bend metal strips such as coils and strips transversely to produce profiles with specific cross-sections. The products produced by the roll forming process are called roll bending profiles. [0003] The traditional roll forming method can only produce profiles with fixed cross-section shapes, but cannot produce variable-section profiles like variable-section hat profiles. In order to meet the production needs of roll-bending profil...
