The invention is characterized in that the invention selects copper material with a copper content of 99.90 to 99.97 percent, adopts surface milling, three-planetary mill rolling, combined pulling and single stretching after undercurrent continuous furnace casting a tube rough, controls the state into a y state; then cuts off the burrs at two ends through track pulling, dimension fixing and cutting off, uses a pressure gas to blow and sweep the copper foam moistened in the tube; injects a specific lubricant with a proper amount on the copper tube and sleeves the copper tube on a mandrel rod of a four-high mil, controls the feeding speed of a feeding wheel within a range of 15 to 30m/h; injects enough lubricant during a rolling process, controls the discharging speed of the four-high mill within a range of 20 to 25m/h; when a finishing mill unit rolls partial products normally, stops the machine and fetch a section to exam the outer diameter, the inner diameter and the numerical value of the wall thickness and adjusts the dimensions of a finishing wheel and a slideway according to the examination result; cleans the finishing copper tube and removes the residual oil stain inside and outside the copper tube; fixes the dimension and saws, as well as cuts off the burrs at two ends and uses a drying gas to blow and sweep the inside and the outside of the tube.
Description
Technical field
The present invention relates to a kind of technique for processing copper pipe for high-precision magnetic controlled anode barrel.
Background technology
In the prior art, the processing method of common copper pipe has two kinds, a kind of be original extruding cold-rolling process be semi-continuous casting-scale sawing-Jia hot piercing, extruding-Pilger two rollers cold rolling-associating drawing-dish draws or vertical pulling-aligning cutting.Another kind is the energy-saving processing method of short flow process of new in recent years research and development, abbreviation continuous casting and rolling method be underflow type horizontal continuous casting-blank surface mill skin-three-roller planetary rolling mill rolling-roll up heavily rolling-associating drawing-high-speed disc greatly to draw-align cutting.The gap of these two kinds of technologies just has on energy consumption, lumber recovery scarcely together, but on the precision of the general copper pipe of processing, all can satisfy its standard-required as water pipe, oil pipe, usual pressure pipe, cooling copper pipe etc., if but production high accuracy copper pipe (magnetic-control anode tube copper pipe) external diameter Φ 39 (error range is in+0.05), (error range is+0.04 for internal diameter Φ 35, in-0.01), wall thickness 2mm (deviation＜0.15 is following), flexibility does not just reach its precision during its length 1200mm below 0.8mm.Since in above two kinds of equipment process to the restriction of tube wall thickness deflection, two kinds of technologies all can't satisfy the high-precision requirement of client to this product, long-term to come domestic employed copper pipe for high-precision magnetic controlled anode barrel all be from external import, and domestic also do not have a tame copper pipe processing enterprise to develop to reach this to manage high-precision processing method and technology.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, and adopt a kind of technique for processing copper pipe for high-precision magnetic controlled anode barrel, spend the wall thickness uniformities by the copper pipe that this processing technology is produced at circumference 360, thickness of pipe wall deviation＜0.12mm scope that 2mm is thick, its flexibility is zero in the long scope of 1-5 rice, and complete straight attitude need be through aligning, thereby reduce equipment investment and save human resources, reduce energy resource consumption.
In order to achieve the above object, the present invention is achieved in that a kind of technique for processing copper pipe for high-precision magnetic controlled anode barrel, it is characterized in that:
A, to select high-quality electrolytic copper material, the content of its copper for use be 99.90-99.97%, adopt the continuous smelting furnace casting of undercurrent type pipe after, mill skin by the surface, after three-roller planetary rolling mill was rolling, associating drawing single stretched again again, state is controlled to be the y attitude; The copper pipe of making through last operation by the crawler type drawing and carry out fixed ruler cutting, excision two burr, be stained with during sawing in the pressed gas scavenging conduit into the copper foam;
B, get the Manufactured copper pipe of above-mentioned operation and inject an amount of special lube, copper pipe is inserted on the axle that is located at four-high mill, by delivery wheel copper pipe is sent in rolling the wheel, it is rolling to start mm finishing mill unit, the feed rate of delivery wheel is controlled in the 15-30m/h scope, the operation of rolling is injected sufficient lubricating oil, impels the roll cooling and makes slideway, roll obtain lubricating fully, and the discharging speed of four-high mill is controlled in the 20-50m/h scope;
C, after mm finishing mill unit normally shuts out portioned product, shut down and to get one section and detect external diameter, internal diameter, wall thickness numerical value, adjust the size of finish rolling wheel and slideway according to testing result, roundly repeatedly be as the criterion to reach satisfied result;
D, will clean through the copper pipe of finish rolling and remove inside and outside residual greasy dirt, the scale sawing is also excised the two ends burr, inside and outside the dry gas scavenging conduit;
E, through said process, obtain the high accuracy copper pipe, the external diameter error range of Φ 20-60mm in ± 0.05mm, the internal diameter error range within ± 0.04mm, the qualified products of wall thickness deviation＜0.15mm of 3-5mm.
The present invention's advantage compared with prior art is, it impels copper pipe in cold working, be equal to constant that pressure is copper under promoting progressively to be shifted to thin by thick, finally reach tubing circumference 360 degree wall thickness uniformities, thickness of pipe wall deviation＜0.15mm scope, the copper pipe of this explained hereafter its flexibility in the long scope of 1-5 rice is zero, complete straight attitude, need be through aligning, thereby reduce equipment investment and save human resources, reduction energy resource consumption, satisfied the high-precision requirement of client this product.
