Abstract
The invention discloses a machining process of a copper pipe, comprising the following steps of: selecting copper pipe billets after being subject to series connection and drawing; putting the copper pipe billets in a plate pulling machine, injecting lubricating oil into the inner wall of the copper pipe and drawing; finishing and winding the copper pipe after the drawing is completed; annealing the copper pipe; and putting finished products in a storage. The machining process disclosed by the invention has the advantages of putting an end to the generation of washing effluents and wastes, increasing the production efficiency and realizing the efficiency, the cleanliness and the environmental protection in the process of producing the copper pipe.
Description
Technical field
The present invention relates to the copper pipe manufacture field, particularly a kind of copper pipe processing technology.
Background technology
At present, for satisfying requirement, when producing inner screw thread copper pipe material and all kinds of light face copper pipe, all need before the annealing to use metal cleaner and sponge or similar medium to clean both at home and abroad to the copper pipe inwall to copper pipe inwall cleannes.Process commonly used is to add suitable cleaning agent and sponge ball number according to copper pipe weight in copper pipe, presses nitrogen to carry out inwall in re-using and blows and clean the copper pipe inwall, cleans and anneals after qualified, and then carry out follow-up deep processing.This process makes that on the one hand process can't serialization production, has prolonged the work period, has reduced production efficiency; Cleaning process has produced a large amount of cleaning waste liquids and sponge the like waste on the other hand, can't recycle, and can cause environmental pollution after the discharging.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of copper pipe processing technology, its objective is and realize that the copper pipe back inwall that stretches no longer cleans and directly carries out following process, thereby stop waste liquid and generation of waste, enhance productivity, realize efficient, cleaning, the environmental protection of copper pipe production process.
For achieving the above object, the present invention has adopted following technical proposals:
A kind of copper pipe processing technology may further comprise the steps:
(1) chooses series connection stretched copper pipe pipe;
(2) the copper pipe pipe is put into plate drawing machine, inject lubricating oil, stretch at the copper pipe inwall;
(3) after stretching was finished, the copper pipe finishing was twined;
(4) annealing;
(5) finished product warehouse-in.
Copper pipe processing technology of the present invention also can be used for the machining internal thread copper pipe, and its method is the step that increases online annealing of copper pipe and copper pipe forming internal threads in the middle of step (2) and step (3).
Lubricating oil in the above-mentioned steps (2) consists of: cycloalkane base oil 60-80%, poly alpha olefin 10-30%, polyglycol ether 10-20%.This kind lubricating oil has higher film strength and lower flash-point, it both can satisfy needs lubricated in the copper pipe drawing process, make that the product inwall of producing is bright and clean, can in annealing process, complete cracking volatilize again, the basic noresidue of annealing back copper pipe inwall, or residual few, can ignore, the mass defect that does not influence client or following process produces.
As required, the stretching step of described step (2) can repeatedly repeat, and repeatedly stretches to meet the requirements up to the back copper pipe that stretches.
Compared with prior art, beneficial effect of the present invention is:
Because the lubricating oil that uses in the drawing process of technology of the present invention can satisfy the requirement lubricated and copper pipe inwall cleaning that stretches simultaneously, therefore the inwall of having exempted after stretching in the traditional handicraft process cleans the oil removing operation, do not need to use cleaning agent, sponge etc. to carry out inwall and clean, and can directly carry out follow-up manufacturing procedure.So not only simplify production process, shortened the production time, improved production efficiency, stopped to clean the generation of waste liquid and sponge the like waste simultaneously, realized efficient, cleaning, the environmental protection of copper pipe production process.And owing to exempted cleaning oil removing operation in the production process,, can save about 50 barrels of metal cleaner, save nitrogen 27932 m by 8000 tons of calculating of monthly output
3, this makes production cost reduce greatly.
And since technology of the present invention be simplification on existing technical process basis and improve, plant machinery etc. is not improved, therefore can directly apply in the existing production technology, simple.
The specific embodiment
For ease of the present invention is further understood, now describe the present invention in conjunction with specific embodiments.
Embodiment 1
Choose up-to-standard series connection stretched copper pipe pipe, this copper pipe pipe is put into plate drawing machine, inject lubricating oil, make the copper pipe inwall all be coated with lubricating oil to the copper pipe inwall; Machine, stretch; After stretching is finished, copper pipe is carried out finishing twine, the packing of directly annealing then promptly makes a light face copper pipe.The lubricant that uses in the above-mentioned steps consists of: cycloalkane base oil 60-80%, poly alpha olefin 10-30%, polyglycol ether 10-20%.
Embodiment 2
Choose up-to-standard series connection stretched copper pipe pipe, this copper pipe pipe is put into plate drawing machine, inject lubricating oil, make the copper pipe inwall all be coated with lubricating oil to the copper pipe inwall; Machine, stretch; After stretching was finished, copper pipe entered online annealing operation and directly anneals, and carried out forming internal threads after annealing is finished, and after twining through the internal thread finishing, the packing of annealing once more promptly makes an inner screw thread copper pipe.The lubricant that uses in the above-mentioned steps consists of: cycloalkane base oil 60-80%, poly alpha olefin 10-30%, polyglycol ether 10-20%.
Claims (3)
1. copper pipe processing technology is characterized in that may further comprise the steps:
(1) chooses series connection stretched copper pipe pipe;
(2) the copper pipe pipe is put into plate drawing machine, inject lubricating oil, stretch at the copper pipe inwall;
