Integrated production line degreasing brazing machining process for air conditioner heat exchanger

Abstract

The invention discloses an integrated production line degreasing brazing machining process for an air conditioner heat exchanger. The process comprises the steps that a), a product is manually fed from a front end of a degreasing furnace; b) the product passes through the degreasing furnace at a constant speed for automatic degreasing and drying; c) a small U-shaped pipe is manually inserted intothe product on line at the front end of a brazing furnace; d) the product enters into the brazing furnace at the constant speed so as to automatically weld the small U-shaped pipe; e) the product discharged from the brazing furnace is manually assembled and other accessories are welded; and f) the product is manually discharged from a tail end of a conveying line 3. In the invention, the machiningprocess is improved, reasonable process modes are adopted for bridging in cooperation with an equipment size height and a transition mode, production efficiency is higher, and a superior product rateof the products is increased; equipment is high in linkage performance and more stable; and a flue gas of a degreasing furnace and a brazing machine can be preheated and recycled to be used by the degreasing furnace, energy consumption of the degreasing furnace is reduced, a temperature of the flue gas of a production line is greatly reduced under an effect of a heat exchanger, and a phenomenon of deflagration of a flue gas exhaust pipeline is further avoided.

Description

technical field [0001] The present invention relates to the processing technology of degreasing and brazing of air-conditioning heat exchangers, more specifically, it relates to a degreasing drying and automatic brazing of small U tubes for evaporators, condensers, fins and long U tubes The brazing process of the integrated energy-saving and environmental protection production line. Background technique [0002] At present, the degreasing equipment and brazing equipment used in the manufacture of air-conditioning heat exchangers are basically not manufactured by the same manufacturer. The configuration of electrical components and communication methods of the two equipments are different. It is inconvenient to connect the systems, which causes a lot of inconvenience to use and maintenance, and also affects production. Efficiency, and lack of oil fume and waste heat recovery and recycling, generally high energy consumption, and lack of exhaust gas treatment system or high cos...
