Abstract
The invention relates to a technological process of production, in particular to a production technology of copper tubes for air conditioners. The production technology of the copper tubes for the air conditioners comprises the following steps of casting, face milling, planetary rolling, tri-connection drawing, bull block drawing, finishing, annealing and packaging and storing. The technological process of the method is simple, the automation degree is high, the production efficiency is also high, the produced copper tubes are slender, walls of the produced copper tubes are thin, the surface quality is high, the content of impurities is low, the yield is high, and the production technology of the copper tubes for the air conditioners is high in efficiency and excellent in performance.
Description
Technical field
The present invention relates to a kind of technological process of production, especially a kind of production technology of idle call copper pipe.
Background technology
Along with social progress, improving constantly of people's income level, the use of air-conditioning is more and more universal.Due to the heat conductivility that copper-base is good, good mechanical performance, make copper pipe as the critical piece of air-conditioning refrigeration system, its production and processing requires more and more higher.But due to the restriction of production technology, the thermal conductivity of existing copper pipe, quality, yield rate, qualification rate and production efficiency need further raising.
Summary of the invention
The present invention is intended to the manufacturing process studying copper pipe, and provide the production technology of an idle call copper pipe, its automaticity is high, qualification rate is high, and its technical scheme adopted is as follows:
A production technology for idle call copper pipe, is characterized in that, the step of the described technological process of production is followed successively by:
A) founding: by raw material be more than 99.97% Cu-CATH-1 plate add in foundry furnace, by high-frequency electromagnetic heating copper coin is melted, add phosphor-copper by proportioning when being warming up to 1030-1045 DEG C; Cast continuously when being warming up to 1075 ± 5 DEG C, in casting process, keep charcoal to cover, prepare the copper tube billet of Φ 92 × 8000mm;
B) milling face: by the oxide skin mill off on copper tube billet surface;
C) planetary rolling: penetrate fixing core print to copper tube billet, pushes in four roller planetary rollings and is rolled, mill speed 45-60 rev/min, feed 3-5mm/ time, prepare the copper pipe of Φ 30 × 2.5mm;
D) three draw: to the copper pipe head rolled out, then with clamp clamping, carry out three and draw, drawing goes out the copper pipe of Φ 25.4 × 1.8mm;
E) dish draws: will join trombone slide head, loads floating core head, adds drawing oil, plate drawing machine carries out high-speed stretch, and point multi-pass stretches, and produces the copper pipe of certain size;
F) finishing: dish is drawn copper pipe to align on finishing machine, cleaned, coiling disc forming;
G) anneal: send into becoming rosette copper pipe in the annealing furnace of nitrogen protection and anneal, purge in coil pipe before annealing;
H) packaging warehouse-in: after the examination and test of products is qualified, carry out on request packing, putting in storage.
Tool of the present invention has the following advantages: technological process is simple, automaticity is high, production efficiency is high, and the thin wall of copper pipe pipe produced is thin, surface quality good, impurity content is low, qualification rate is high, is a kind of production technology of idle call copper pipe of efficient, function admirable.

D) three draw: to the copper pipe head rolled out, then with clamp clamping, carry out three and draw, drawing goes out the copper pipe of Φ 25.4 × 1.8mm;
E) dish draws: will join trombone slide head, loads floating core head, adds drawing oil, plate drawing machine carries out high-speed stretch, and point multi-pass stretches, and produces the copper pipe of certain size;
F) finishing: dish is drawn copper pipe to align on finishing machine, cleaned, coiling disc forming;
G) anneal: send into becoming rosette copper pipe in the annealing furnace of nitrogen protection and anneal, purge in coil pipe before annealing;
H) packaging warehouse-in: after the examination and test of products is qualified, carry out on request packing, putting in storage.
Describe the present invention by way of example above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
