Abstract
The present invention relates to integrated process of machining the transition joint of capillary copper tube in a reaming device comprising one clamping mechanism, one reaming core and one beading core. The process includes the following steps: 1. reaming one end of capillary copper tube to designed size with several reaming cores while ensuring the wall thickness of the tube not smaller than 0.5mm and applying lubricant oil; 2. beading the reamed end with beading core to form transition joint; and 3. cutting the end of the transition joint to obtain the capillary copper tube with a transition joint. The capillary copper tube with integrated transition joint is superior to that produced through welding and has high cleanliness and no influence on the flow.

In both welding processes, not only will guarantee its fastness, avoid welding blind spot generation leakage, and the material face of solder joint can not be too thick, in case hole plug in the capillary.If existing these above-mentioned problems all to influence its refrigeration of air-conditioning exerts an influence to environment with the leakage that cold-producing medium may take place.In addition, also increased production cost in the welding process.
Summary of the invention
The integral processing method that the purpose of this invention is to provide a kind of transition interface of copper capillary tube has incorporate transition interface on the copper capillary tube by this processing method acquisition.
The present invention can be implemented by the following technical programs: a kind of integral processing method of transition interface of copper capillary tube, a Counterboring apparatus at first is provided, this Counterboring apparatus comprises clamp mechanism, reaming core print and reducing core print, described clamp mechanism is used for copper capillary tube is fixed, described reaming core print can carry out reaming to copper capillary tube, and described reducing core print can carry out reducing to the copper capillary tube after the reaming; Described processing method comprises the steps:
(1) with copper capillary tube blank clamping on the clamp mechanism of described Counterboring apparatus, utilize the reaming core print of different-diameter copper capillary tube one end to be carried out at least twice continuous reaming, make the external diameter of this end satisfy the setting requirement, guarantee that after each reaming the pipe thickness of copper capillary tube is more than or equal to 0.5mm, in addition, will be on copper capillary tube inwall or reaming core print when reaming coating lubricating oil;
(2) utilize clamp mechanism that copper capillary tube is carried out the secondary clamping, utilize described reducing core print that copper capillary tube is carried out reducing by an end of reaming, make this end form the transition interface;
(3) port part with described transition interface trims, and promptly gets the copper capillary tube with the transition interface.
Also the copper capillary tube of described band transition interface to be cleaned with cleaning agent after the described step (3).
The beneficial effect that compared with the prior art the present invention obtains is: the copper capillary tube that method of the present invention processes is the smooth rounding of its surfaces externally and internally not only, and comprehensive letter can be good.And since the transit joint that processes be integrated setting on copper capillary tube, need not welding thereby the problem that in the installation process in later stage, does not exist capillary endoporus cleannes and flow to change than prior art.
