The Forming Technique for Gas-collecting Aluminum Flat Tube with High Frequency Welding in Intercooler

In order to meet the demands of high-speed and high-precision production for aluminum flat tube in modern automobile manufacture industry, a direct cold plastic forming technique of gas-collecting aluminum flat tube from aluminum strips is proposed, specifically, the problems including the modular integration of rollers, continuous forming in the deformation zone and speed match between different rollers are emphatically studied. Experimental results prove that the designed process technique and equipment are reasonable and efficient, and can fulfill the requirements of practical production as well.
