Abstract
The invention discloses a manufacture method of a high-conductivity and high-hardness micropore copper pipe, relating to a manufacture method of a micropore copper pipe. The manufacture method comprises the steps of firstly selecting and drawing a copper pipe with a state of Y, a grade of red copper, chromium zirconium copper, chromium bronze or copper-argentum alloy, an external diameter of 3-16mm, a hole diameter of 1.3-3.0mm and a length of 5-2500mm in a previous process and carrying out multiple times of rotary swaging molding by adopting a rotary swaging machine to obtain a copper pipe with a hole diameter of 0.08-3.0mm, wherein a steel wire with the diameter of less than that of the copper pipe is plugged into an internal hole of the copper pipe along with the rotary swaging in a rotary swaging process, the steel wire and a rotary swaging mould are replaced at each time of rotary swaging, and the diameter of the steel wire is gradually reduced.
Description
Technical field
The present invention relates to the preparation method of micropore copper pipe, relate in particular to the high-precision aperture of a kind of high conductivity high rigidity micropore copper pipe manufacture method.
Background technology
The special ultra-fine hole of high conductivity high rigidity is the energy-efficient new product that industry needs, and never solves for a long time the special ultra-fine 0.08 ~ 3.0mm of high conductivity high rigidity aperture both at home and abroad, because people can't beat to this little hole with drill bit.
Chinese patent CN101249521 discloses a kind of manufacture method of posted sides micropore copper pipe, the manufacturing field that belongs to copper tube, be M with state, the trade mark is T2, external diameter is 38-50MM, wall thickness is 5-6MM, the copper tube sky that length is not limit draws, annealing, sky draws, after the annealing in process, in centre bore, put into core rod, sky draws, changing behind little No. one core rod again, sky draws, circulation is until copper tube is drawn into state is Y successively, external diameter is below the 12MM, center-hole diameter is 0.5-1MM, it is thicker that the present invention can produce wall, centre bore is smaller, and the copper pipe of core shift not, reduced the production cost of manufacturer, although technical scheme of the present invention can prepare the copper pipe of small-bore, but still be difficult to meet the demands and make 0.1 ~ 0.5mm even the copper pipe of small-bore more, and the copper pipe that adopts technique scheme to make, yield rate has much room for improvement, and endoporus fineness is inadequate, is approximately 1.08um, can not satisfy the making requirement of some best bright finish copper pipe, have much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the present invention makes Kong Weigeng thin, and precision is higher, and the aperture is brighter and cleaner, and hardness is harder.As require the not bery high product of aperture light cleanliness, and calculate and can not wear steel wire empty receipts of swaging, reach and shrink the aperture when shrinking external diameter, a kind of any surface finish is provided, the accuracy of manufacture is high, the high conductivity high rigidity micropore copper pipe manufacture method that production efficiency is high.
The present invention is for solving the problems of the technologies described above, provide following technical scheme: a kind of high conductivity high rigidity micropore copper pipe manufacture method, it is characterized in that may further comprise the steps: at first selection mode is Y, the trade mark is red copper, chromium zirconium copper, chromium-bronze or Kufil, by front road drawing external diameter 3 ~ 16mm, aperture 1.3 ~ 3.0mm, length is the copper pipe of 5 ~ 2500mm, the moulding of repeatedly swaging makes the copper pipe that the aperture is 0.08 ~ 3.0mm through swager, fill in the steel wire less than the copper pipe diameter in the described rotary swaging process in the copper pipe endoporus while swaging, swage at every turn and change steel wire and the mould of swaging, steel wire diameter diminishes one by one.
As preferably, described steel wire grows copper pipe 2 ~ 3cm.Because want development length 20% ~ 27%(when swaging according to the variable of swaging), so when swaging, will constantly fill in synchronously follow-up to steel wire.
Beneficial effect of the present invention: the present invention is by on the basis of aperture, with a kind of rotary swaging equipment and mould, the required steel wire of aperture string carries out swaging for 1 ~ 3 time shrinking and reaches aperture 0.08 ~ 3.0mm, and advantage: yield rate is up to 98%, off-centre≤0.01mm, aperture light cleanliness 0.25um, hardness is high, copper tube, Kufil pipe HRB 〉=65, chromium-zirconium-copper tubes, chromium-bronze pipe HRB 〉=86, low cost of manufacture is convenient to safety operation.
