(1) undergauge process is carried out to thin-wall aluminium pipe
The external diameter being installed with the pipe end of the standby thin-wall aluminium pipe to adopting by general pier is reduced, and forms one throat structure;
(2) inner support tube is set off
By the mode of manual assembly, inner support tube accurate good is in advance inserted thin-wall aluminium pipe pipe top inside to the position of reducing;
(3) processing rubber pipe thread indent and chamfering
Use the thin-wall aluminium pipe tube end maching of spinning machine outside described inner support tube position to go out rubber pipe and withhold groove, and process chamfering on the pipe top of described thin-wall aluminium pipe, described inner support tube can be fixed on inside the pipe end of thin-wall aluminium pipe by described reducing and chamfering, avoid inner support tube to be shifted and cause structural failure.
Further, described thin-wall aluminium pipe is the aluminum pipe of wall thickness 0.75 ~ 1mm.
Further, described inner support tube adopts 6063T IV type aluminium.
Optionally, the thick 0.75 ~ 1mm of 6063T IV type aluminium of employing.
Good effect of the present invention is:
(1) provide and a kind of there is the air-conditioning thin-wall aluminium pipe adding fixed end, the aluminum pipe of wall thickness 0.75 ~ 1mm can be adopted, only set off inner support tube in the inside of pipe end, form the thin and air conditioner connecting pipe that pipe end is strengthened of tube wall, comparatively existing product is structurally significantly improved.
(2) have the processing method of the air-conditioning thin-wall aluminium pipe adding fixed end described in, the technology and equipment of existing maturation can be utilized to process described air-conditioning thin-wall aluminium pipe, step is reasonable, easy and simple to handle, facilitates industrialization manufacture.
(3) structure that the present invention has an air-conditioning thin-wall aluminium pipe adding fixed end can meet rubber pipe and withhold requirement to aluminum pipe intensity, do not affect other production links again, reduce again the weight of car air-conditioner product on the whole simultaneously, reduce the cost of raw material, meet the requirement of present enterprise to car air-conditioner tubing.
