Embodiment Construction

[0028] like Figure 5 As shown, the bottom of the reservoir body 1 is provided with a liquid outlet 3, which is enlarged as Figure 6-Figure 9 As shown, there is a vertical tubular flange 6 downward along the central axis on the liquid outlet 3, and the inner iron pipe 4 is flared (see Figure 7 ) or flanging (see Figure 9 ) or maintain the original straight tubular shape (see Figure 8 ), and then the inner iron pipe 4 is pressed into the tubular flange 6 of the reservoir body 1, and the inner iron pipe 4 is flared or straight or the outer side of the flange is provided with three or four convex ribs 8 (can be set according to the inner iron pipe 4. Increase the ribs 8 to 5-8 according to the size of the diameter), so that the inner diameter of the inner iron pipe 4 and the tubular flange 6 of the liquid reservoir body 1 produces an interference fit, and leaves a welding gap 9, and then the outer copper pipe 5 Put it into the flaring or straight pipe or flanging of the in...

Abstract

The machining process of liquid pipe for gas-liquid separator includes setting liquid outlet in the bottom of the liquid storage unit, forming downward vertical turned edge, expanding the inner iron tube, pressing the inner iron tube into the turned edge, setting three or four raised ribs with upper flange in the expanded part of the inner iron tube for interference fitting between the inner irontube and the tubular turned edge of the liquid storage unit body while retaining welding interval, setting the outer copper tube inside the expanded port of the inner iron tube and final welding to form one integral. The machining process of the present invention is simple, reasonable, high in production efficiency and high welding quality.

Description

technical field [0001] The invention relates to a welding processing method, in particular to a processing method for an infusion tube of a gas-liquid separator. Background technique [0002] In the existing traditional household air-conditioning gas-liquid separator (accumulator) such as figure 1 As shown, it is welded with a copper infusion tube 2 at the bottom liquid outlet 3 of its liquid reservoir body 1 and connected with the bottom of the liquid reservoir body, its enlargement is as follows figure 2 shown. At present, this technology is widely used to achieve mass production. Because the infusion tube is made of copper, its manufacturing cost is 3 to 4 times that of iron infusion tubes, and the iron tube is used as the internal infusion tube of the gas-liquid separator (reservoir). It does not affect the performance of the gas-liquid separator, but the application of low-cost iron infusion pipes is affected because the welding technology between the liquid reservoi...
