Abstract
The invention relates to a machining process, in particular to a machining process of a copper pipe for an ultrathin-walled air conditioner. The machining process includes casting, surface milling, planetary rolling, combined drawing, bull block drawing, finishing, annealing and packaging. The machining process is short in operation flow, high in automation level and excellent, and produced copper pipes are thin in walls, good in surface quality, low in impurity content and high in yield.
Description
Technical field
The present invention relates to a kind of processing process, especially a kind of processing process of ultra-thin-wall idle call copper tube.
Background technology
Along with social progress, improving constantly of people's income level, the use of air-conditioning is more and more universal.And copper pipe is as the critical piece of air-conditioning refrigeration system, production and processing requires more and more higher, and especially ultra-thin-wall copper tube is with its light weight, efficient, can meet the development need of air-conditioner miniaturization, economization, high energy efficiency.Due to the restriction of production technology, the thermal conductivity of existing copper pipe, thin-walled property need further raising.
Summary of the invention
The present invention is intended to research and solve the problems referred to above, provide a kind of processing process of ultra-thin-wall idle call copper tube, the red copper tube wall that it is produced is thinner, heat dispersion better, and be the ultra-thin-wall copper tube processing process of a kind of advanced person, its technical scheme adopted is as follows:
A processing process for ultra-thin-wall idle call copper tube, is characterized in that, the step of described processing process is followed successively by:
A) founding: by raw material be more than 99.95% Cu-CATH-1 plate add in foundry furnace, by high-frequency electromagnetic heating copper coin is melted, keep charcoal to cover in casting process, add phosphor-copper by proportioning; Cast continuously, casting temperature 1075 ± 5 DEG C, prepares the copper tube billet of Φ 90 × 8000mm;
B) milling face: by clean for the oxide skin milling cutter milling on copper tube billet surface;
C) rolling: the copper tube billet of Φ 90 × 8000mm is put into core print, pushes in three-roller planetary rolling mill and be rolled, prepares the copper pipe of Φ 30 × 2.5mm;
D) associating drawing: to the copper pipe head rolled out, then with clamp clamping, carries out three and draws, prepare the copper pipe of Φ 22 × 2.0mm;
E) dish draws: will join trombone slide head, loads floating core head, adds drawing oil, plate drawing machine carries out high-speed stretch, point passage multi-drawing, and producing thickness is the copper tube that 0.18-0.20mm is thick;
F) finishing: draw copper pipe to repair on finishing machine to dish, align, clean, nondestructive inspection, coiling disc forming;
G) anneal: send into becoming rosette copper pipe in the annealing furnace of nitrogen protection and carry out bright annealing;
H) pack: pack on request after the examination and test of products is qualified.
Tool of the present invention has the following advantages: method operating process of the present invention is short, automaticity is high, the red copper tube wall produced is thin, surface quality good, impurity content is low, qualification rate is high, is a kind of processing process of preparation ultra-thin-wall idle call copper tube of excellence.
