Problems solved by technology
[0003] The problems existing in this technology are: steel plate sleeve cutting; equal arc cutting (through scribing, gas cutting, grinding, tailor welding, calibration, turning and other processes) to complete, there are many processes and a large number of workpieces. It is impossible to achieve one-time molding, but to cut into small pieces by equal arcs and tailor welding. Although a little material can be saved in this way, it brings a series of disadvantages to the subsequent work, which is labor-intensive, time-consuming, and consumes more oxygen. , acetylene, grinding wheel, welding rod, etc., poor process assurance and low production efficiency

The invention provides a flange roller forming method. One-time forming is achieved through the flange roller forming method, and the production efficiency is high. According to the technical scheme, one-time forming is conducted through special roller forming equipment, and the specific forming process includes the steps of driving a pressing mold disc and clamped flat steel to rotate and enter a deformation area through a motor and a gearbox, beginning to conduct deformation, enabling the pressing mold disc and the clamped flat steel to further move into a pressing forming area, conducting forming through mutual work of a pressing forming wheel and the pressing mold disc, enabling the pressing mold disc and the clamped flat steel to enter a rolling and correcting roller set along with rotation movement to be rolled, flattened, corrected and protected, completing flange forming, and conducting unloading.
Description
technical field [0001] The invention relates to a flange forming method, in particular to a flange rolling forming method. Background technique [0002] Flanges are widely used in various industries such as: equipment manufacturing, pipeline installation, automobile manufacturing, food and engineering machinery and other machinery industries. [0003] The problems existing in this technology are: steel plate sleeve cutting; equal arc cutting (through scribing, gas cutting, grinding, tailor welding, calibration, turning and other processes) to complete, there are many processes and a large number of workpieces. It is impossible to achieve one-time molding, but to cut into small pieces by equal arcs and tailor welding. Although a little material can be saved in this way, it brings a series of disadvantages to the subsequent work, which is labor-intensive, time-consuming, and consumes more oxygen. , Acetylene, grinding wheel, welding rod, etc., poor process assurance and low p...
