Abstract
The utility model discloses a structure of a lamellar brazing ring for brazing an aluminum alloy pipe of a household water heater. The lamellar brazing ring is formed by integrating a lamellar outer ring and a convex ring. Lamellar aluminum alloy brazing materials are once punched into the lamellar brazing ring, one side of the lamellar outer ring of which is provided with the convex ring, and the lamellar outer ring and the convex ring are concentric circles. The internal diameter of the convex ring is equal to the internal diameter of the lamellar outer ring. The lamellar brazing ring is sleeved into a port of an aluminum alloy hot water pipe from a plane side, and the convex ring and the port of the aluminum alloy hot water pipe are simultaneously inserted into an inlet and an outlet and a U-shaped pipe of an aluminum alloy heat exchanger and sent into an automatic brazing furnace for welding. The utility model has uniform heating melting, precise positioning, large welding area, resource saving and stable product quality, wherein the brazing yield reaches 98-99.5 percent.
Description
Technical field
The utility model relates to pot-type boiler aluminium-alloy pipe soldering soldering ring, particularly a kind of pot-type boiler aluminium-alloy pipe soldering sheet soldering ring.
Background technology
The heat exchanger of conventional domestic water heater inside is a copper material, and the hard tube of using because of water flowing must make it close adhesion by welding with heat exchanger shell, so hard tube and housing must adopt copper material.Copper material as the shortcoming of hot-water line is: the costing an arm and a leg of circular copper pipe and copper case material, and than great, poor processability.The hot-water line of the heat exchanger of pot-type boiler inside and heat exchanger began to adopt aluminum alloy materials in recent years, and the price of aluminum alloy materials is lower, was 1/3rd of circular copper pipe price, the aluminum alloy materials light specific gravity, processing characteristics is good, and China's bauxite resource is abundant, not influenced by import.But the welding process requirement of aluminum alloy heat water pipe and aluminum alloy heat exchanger import and export and " U " type pipe is very strict, between sealing requirements very high, withstand voltage need reach 1.5MPa.At present, the welding material shape of aluminum alloy heat water pipe and aluminum alloy heat exchanger import and export and " U " type pipe is the soldering ring of cross circular section shape.The soldering ring set of cross circular section shape is gone into the port that the aluminum alloy heat water pipe need weld, after pegging graft with aluminum alloy heat exchanger import and export and " U " type pipe, send into again in the automatic brazing stove and weld.The shortcoming of the soldering ring of cross circular section shape is that cross section is that the soldering loop mapping of toroidal is accurate inadequately, melted by heat is inhomogeneous, owing to dredge close down on the effect welding material of gravity, cause the qualification rate of aluminum alloy heat water pipe and aluminum alloy heat exchanger import and export and " U " type pipe welding to have only about 85%～87%, underproof welding product can only lean on artificial repair welding, influence product quality, the waste resource.
Summary of the invention
The purpose of this utility model is at above-mentioned shortcoming, develop a kind of pot-type boiler aluminium-alloy pipe soldering sheet soldering ring, the sheet brazing material is pressed into the sheet annulus of middle band bulge loop, this ring main feature is on the size Control of bulge loop and outer shroud, bulge loop is by punch forming, the flange height just is the diameter of traditional round shape weld-ring, bulge loop not only has spacing effect, and when going into the slice weldering, because its thin thickness, and with aluminium-alloy pipe be axial seal so capillary joint filling effect is fine, outer shroud then is the replenishing of melting welding pricker of radial seal, and weld strength is increased.This sheet soldering ring, melted by heat is even, and the location is accurate, bonding area is big, and the soldering yield rate reaches 98%～99.5%, economizes on resources constant product quality.
The purpose of this utility model is achieved in that
The soldering of pot-type boiler aluminium-alloy pipe is made up of sheet outer shroud and bulge loop one with sheet soldering ring.Is thickness the sheet soldering ring that a side that the sheet aluminium alloy brazing material of 3-6 millimeter once strikes out the sheet outer shroud is provided with bulge loop, and the external diameter of sheet outer shroud is the 15-17 millimeter, and the internal diameter of sheet outer shroud is the 10-11 millimeter.One side of sheet outer shroud is provided with bulge loop.Sheet outer shroud and bulge loop are concentric circles.The external diameter of bulge loop is the 11-13 millimeter, and the internal diameter of bulge loop is identical with the internal diameter of sheet outer shroud, and the height of bulge loop is the 1.3-1.6 millimeter.
Above-mentioned sheet soldering ring is inserted in aluminum alloy heat water pipe port from planar side, and bulge loop and aluminum alloy heat water pipe port inject aluminum alloy heat exchanger import and export and " U " type pipe simultaneously, send in the automatic brazing stove and weld.
The utility model melted by heat is even, and the location is accurate, bonding area is big, and the soldering yield rate reaches 98%～99.5%, economizes on resources constant product quality.
