Abstract
A method for connecting capillary tube to inner-casing refrigerating coil is that, the end of inner-casing refrigerating coil is molded into intermediate holed and two side flatted pipe joint, then inserted with capillary tube, finally welded, the welding structure guarantees welding quality and efficiency and consistency of assembling and welding
Description
Technical field
The present invention relates to a kind of inner casing refrigerating coil and connect method capillaceous, belong to the pipeline welding technology field of the household refrigerator-freezer of family expenses and commercialization.
Background technology
Common household refrigerator-freezer pipeline welding is after adopting pipeline one end reaming, other end shrinkage cavity, insert welding mutually, such welding manner differs less pipeline to caliber, applicability is better, but even caliber is differed the pipe reaming that is connected more greatly, the requirement that shrinkage cavity can not reach technology, this adopts new technology to solve this problem with regard to requiring us.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of inner casing refrigerating coil to connect method capillaceous, to improve the pipeline welding quality.
For achieving the above object, technical program of the present invention lies in having adopted a kind of inner casing refrigerating coil to connect method capillaceous, this method is with holes two flat-sided real pipe joints in the middle of the tube head with the inner casing refrigerating coil is pressed into, and inserts capillary then, last welding fabrication.
Described pipe joint be that a hole is 2mm-4mm.
New inner casing refrigerating coil and Welding Structure capillaceous are with holes two flat-sided real duckbill pipe joints in the middle of with shaping mould the mouth of pipe of inner casing refrigerating coil being configured as earlier, forward to again on the production line and to insert the capillary welding, adopt method of the present invention can guarantee the uniformity of welding quality and welding efficiency and assembling, welding.
Description of drawings
Fig. 1 is than the sectional view behind the mould molding of extra heavy pipe road;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the overlooking surface figure of Fig. 1;
Fig. 4 connects structural representation capillaceous for the inner casing refrigerating coil than the extra heavy pipe road.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, inner casing refrigerating coil of the present invention connects method capillaceous: the tube head of inner casing refrigerating coil is pressed into middle with holes, two flat-sided real pipe joints, insert capillary then, last welding fabrication, wherein pipe joint between the hole be 3mm.During concrete enforcement, the design mould, with diameter is in the drift insertion extra heavy pipe of 3mm, utilization be contained on the equipment mould with extra heavy pipe 3 with holes in the middle of being squeezed into be that interstitial hole 2, two flat-sided realities are the Duckbill type pipe joint of flat real part 1, drift is pulled out in die sinking then, after the moulding as Fig. 1, Fig. 2, shown in Figure 3.The extra heavy pipe that is connected with mould molding after, capillary 4 is inserted be welded into as shown in Figure 4 then, so promptly may guarantee the quality of welding, can guarantee the uniformity of pipeline grafting again.
Claims (2)
1, a kind of inner casing refrigerating coil connects method capillaceous, it is characterized in that: this method is with holes two flat-sided real pipe joints in the middle of the tube head with the inner casing refrigerating coil is pressed into, and inserts capillary then, last welding fabrication.
