Dynamic and intelligent continuous operation control method and production line for aluminum welded pipes

Abstract

The invention discloses a dynamic and intelligent continuous operation control method for aluminum welded pipes. The method includes the following steps that (1) an aluminum welded pipe production line is arranged; (2) a dynamic and intelligent control device is arranged; (3) a tension sensor is used for sampling strip tension, a photoelectric detection sensor is used for sampling the conveying speed, a position sensor is used for sampling roller positions, and respective sampled data are transmitted to a control unit; and (4) aluminum welded pipe continuous operation is achieved through dynamic and intelligent control over an aluminum strip tension device, a pinch roller device and a forming device used for ultra-thin-wall aluminum strips on the aluminum welded pipe production line. The invention further discloses the production line adopting the control method. A strip unwinding closed-loop control system comprises a strip unwinding closed-loop control system body, a pinch roller closed-loop control system and a regulation adjusting closed-loop control system, the tension, the conveying speed and roller positions are sampled correspondingly, and through comparison with parameters set in advance through an HMI, dynamic and intelligent control over the aluminum welded pipes is achieved.

Description

technical field [0001] The invention relates to the technical field of processing equipment for aluminum radiating pipes, in particular to a method and production line for dynamic intelligent control of continuous operation of aluminum welded pipes. Background technique [0002] Ultra-thin-walled (0.15-0.50mm) aluminum and aluminum alloy composite pipes are widely used and indispensable materials in equipment powered by internal combustion engines such as automobiles, air conditioners, locomotives, engineering machinery, and ships. According to the different requirements of the product, the selection of the specific material and structure of the pipe is different, but the most representative of the selection of the manufacturing process is the high-frequency welding process. [0003] The market capacity of aluminum alloy ultra-thin-walled pipes is huge, and the annual demand of the domestic automotive switch industry alone is nearly 3 billion yuan. At present, the advanced ...

AI Technical Summary

Problems solved by technology

At present, the advanced production technology of ultra-thin-walled aluminum welded pipes for heat exchangers is mainly mastered by the United States, Japan, Germany and other countries, while the domestic production of ultra-thin-walled aluminum welded pipes is relatively low in intelligence, and the proficiency of equipment debugging and on-site operators The dependence is high, and it cannot effectively guarantee the stability of the high-frequency welding quality of aluminum alloy ultra-thin-walled tubes
