Embodiment Construction

[0053] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0054] According to an embodiment of the present invention, such as Figure 1-Figure 6b As shown, a method for roll forming of long profiled bars is provided.

[0055] The roll forming method for elongated profiled materials in this embodiment adopts the roll forming process, specifically: rolling metal flat strips such as coils and profiles through sequentially configured multi-pass forming rolls. When the flat metal strip is fed forward, the flat metal strip is continuously bent transversely to make a preset specific end-face profile processing method. Roll forming is a material-saving, energy-saving and efficient sheet metal forming process and new technology for ...

Abstract

The invention discloses a method for roll forming of a strip-shaped irregular sectional material. The method comprises the steps of arranging a rolling mill set and a correction tool according to the end face shape of a preset sectional material and a straight strip or arc-shaped structure; analyzing the deformation process of a to-be-rolled sectional material, determining the rolling pass number and the rolling wheel shape, and calculating the processing progress; and adopting the arranging rolling mill set and the correction tool to gradually bend the to-be-rolled sectional material into the sectional material with the needed end face according to the processing progress obtained by calculation. The method for roll forming of the strip-shaped irregular sectional material can overcome the shortcomings of small applied range, low production efficiency, poor product quality and high processing cost in the prior art and have the advantages of being wide in applied range, high in production efficiency, good in product quality and low in processing cost.

Description

technical field [0001] The invention relates to the technical field of profile processing, in particular to a roll forming method for a long profile. Background technique [0002] Section bar is an object with a certain geometric shape made of iron or steel and materials with certain strength and toughness (such as plastic, aluminum, glass fiber, etc.) through rolling, extrusion, casting and other processes. [0003] The process of producing profiles by extrusion. Extruded profiles are divided into two categories: hollow profiles and solid profiles. Hollow profile refers to a profile with one or more closed through holes on the transverse end surface. There are more than 30,000 varieties and specifications of extruded profiles, especially aluminum profiles, which amount to more than 24,000. Followed by copper profiles, magnesium profiles and steel and plastic profiles. Solid extruded profiles account for about 65% of all extruded profiles, and special-shaped end profiles...
