Abstract
The present invention relates to a method for connecting a refrigerating coil of an inner casing with a capillary tube, which comprises the following steps: a coil head of a refrigerating coil of an inner casing is pressed into a tube joint, the middle of the tube joint is provided with holes, and both sides of the tube joint are flat; then, the tube joint is inserted in a capillary tube; finally, formation by welding is carried out. The welded structure of new coils and the capillary tube is that the coil head of the refrigerating coil of the inner casing is formed into a duckbill-shaped tube joint by a forming mold, the middle of the duckbill-shaped tube joint is provided with holes, and both sides of the duckbill-shaped tube joint are flat; then, the duckbill-shaped tube joint is changed to a production line, inserted into the capillary tube and welded. Thereby, the present invention ensures the welding quality, the welding efficiency and the uniformity of assembly 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 refrigerator of family expenses and commercialization.
Background technique
Common refrigerator pipeline welding is after adopting pipeline one end reaming, the 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 tube then, last welding fabrication.
The diameter of the intermediate hole of described pipe joint is 2mm-4mm.
New inner casing refrigerating coil and welded structure capillaceous are with holes two flat-sided real duckbill pipe joints in the middle of with forming die 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 tube welding, adopt method of the present invention can guarantee the conformity of welding quality and welding efficiency and assembling, welding.
Description of drawings
Fig. 1 is than the sectional view behind the mould-forming 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.
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 tube then, last welding fabrication, wherein the intermediate hole of pipe joint is 3mm.During concrete enforcement, the design shaping die, with diameter is in the drift insertion extra heavy pipe of 3mm, utilization be contained on the equipment shaping die with extra heavy pipe 3 with holes in the middle of being squeezed into be that intermediate 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-forming after, capillary tube 4 is inserted be welded into as shown in Figure 4 then, so promptly may guarantee the quality of welding, can guarantee the conformity 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 tube then, last welding fabrication.
2, method according to claim 1 is characterized in that: the diameter of the intermediate hole of described pipe joint is 2mm-4mm.
