In order to realize the metallurgical binding of aluminium and copper, can carry out internal pressurization formula annealing in process to the aluminum-cladding copper pipe material after the drawing.
Be example now, its production process is described with production φ 9.52mm * 0.5mm, the long-pending aluminum-cladding copper pipe that accounts for the section gross area 15% of tubing section copper aspect.
The external diameter φ 9.52mm of this production tube, internal diameter φ 8.52mm, wall thickness are 0.5mm, and wherein aluminum layer thickness is 0.425mm, and copper layer thickness is 0.075mm.
The external diameter that now designs the aluminum-cladding copper pipe base is φ 11.50mm, and internal diameter is φ 9.50nn, and an ancient piece of jade, round, flat and with a hole in its centre is thick to be 1mm.Selecting thickness for use is that 0.3mm, width are that the T2 copper strips of 31.7mm and thickness are that 0.7mm, width are that the L2 aluminium strip of 37.4mm is raw material.
At first copper strips being welded into external diameter with welded tube mill by above-mentioned steps is that φ 10.10mm, internal diameter are the pipe of φ 9.50mm.
As shown in Figure 1 aluminium strip 20 and copper pipe 19 are sent in the production line of aluminum-cladding copper pipe simultaneously.At first copper pipe is aligned and the polish-brush outer surface; Aluminium strip is by slicing mould, will coat face and the both sides solder side is taken 0.05mm. off.Enter then in the cladding welder, make aluminium strip progressively be rolled into tubulose and form a longitudinal joint around copper pipe, behind alternating-current argon arc welder welding longitudinal joint, forming external diameter is that φ 11.90mm, internal diameter are the aluminum pipe of φ 10.50mm, and wherein being with external diameter is that φ 10.10mm, internal diameter are that φ 9.50mm copper pipe forms the aluminum-cladding copper pipe base.The difference of aluminum pipe internal diameter and copper pipe external diameter is about 0.4mm.
Then the aluminum-cladding copper pipe base enters in the drawing equipment, carries out the drawing of 2 passages with the tube-drawing die device that has floating core head.During first passes of drawing, the internal diameter of drawing die is φ 10.75mm, and the external diameter of floating core head is φ 9.15mm; During second passes of drawing, the internal diameter of drawing die is 10.00mm, and the external diameter of floating core head is 8.80mm.Obtain the aluminum-cladding copper pipe base that aluminium lamination and copper layer fit tightly.
After putting into a certain amount of material of getting angry (as urea) in the above-mentioned aluminum-cladding copper pipe base or charging into a certain amount of clear water, two ends is sealed.Sealing means can select to push the mode of flattening, makes the termination be in sealing state.Put into heating furnace then, be heated to about 350 ℃, be incubated 1 hour and carry out diffusion annealing.Come out of the stove after being cooled to normal temperature.Make aluminium lamination and copper layer realize metallurgical binding, and eliminated the work hardening phenomenon.In annealing process, the pressure of aluminum-cladding copper pipe inner chamber is controlled at 4MPa or 5MPa or 6MPa, promptly between 4-6MPa all can, to guarantee the metallurgical binding of aluminium and copper.
Aluminum-cladding copper pipe after the heat treatment has accurate dimensions and regular shape in order to make it, carries out a drawing again according to the suitable mould of preferred dimension that requires of finished size, and making its external diameter is φ 9.52mm, and internal diameter is φ 8.52mm, and an ancient piece of jade, round, flat and with a hole in its centre is thick to be 0.5mm.
