Abstract
The utility model relates to a be used for brazed stairstepping brazing filler metal of pipe fitting multilayer suit, the brazing filler metal is the annular complex ring of brazing, and the cross section of brazing filler metal is the stairstepping. The utility model discloses have little step and major progress, step cooperation between little step and conical duct, the straw, step cooperation between major progress and pipe, the conical duct. The utility model discloses have the breach, this breach can be facilitated the utility model discloses the suit is on needs welded pipe. The utility model discloses the structure is succinct, can direct suit on the tubular structure, through step structure and the cooperation of many steps, the compound brazing filler metal that is formed by brazing solder and borer agent mixture is favorable to the utility model discloses directly braze convenient and practical.
Description
Technical field
This utility model relates to a kind of stairstepping solder for pipe fitting multi-deck nested soldering, it is adaptable to ratio-frequency welding and gas brazing etc., can be widely applied in the soldering between the steel of multiple industries such as refrigeration, machinery.
Background technology
The structure of the suction nozzle soldering of original compressor as it is shown in figure 1, wherein the suction pipe 4 ' of conduit 1 ', conical pipe 3 ' and reservoir be copper material or copper facing part, cost is high.Being connected by soldering processes between conduit 1 ', conical pipe 3 ' and suction pipe 4 ', solder adopts low silver or silver-less solder.For reducing cost further, part copper pipe is replaced with steel pipe by compressor producer, and design structure is adjusted, and such as Fig. 2, causes that original method for welding cannot meet requirement, therefore the brazing material that the later stage adopts is brazing solder.
Brazing solder can be used for steel and is connected with the soldering of steel with steel, copper, excellent performance after welding, but uses and must be equipped with brazing flux use when pyrite soldering steel and steel, otherwise will cause that solder can not be sprawled at mother metal moistened surface, it is impossible to welding.And the coating of brazing flux can increase the operating time, it is unfavorable for the needs of automated production.
There is ledge structure (referring to Fig. 2 arrow indication place) in suction nozzle soldered joint simultaneously, and have two bigger gaps, the collar need to be distinguished for filling gap when using solder ring, further increase soldering time.
Summary of the invention
The purpose of this utility model is in that to overcome above shortcomings in prior art, it is provided that the solder of stairstepping many lamellar spacings soldering of a kind of new construction.
The technical scheme in the invention for solving the above technical problem is:
A kind of stairstepping solder for pipe fitting multi-deck nested soldering, in the form of a ring, the cross section of solder is stairstepping to described solder, and stairstepping is conducive to the disposable soldering of multi-step, convenient and practical.
This utility model has small stair and big step, and between small stair with conical pipe, suction pipe, step coordinates, and between big step with conduit, conical pipe, step coordinates, and is conducive to this utility model to be sleeved on tubing and directly welds.
This utility model has breach, and owing to this utility model is easily bent deformation, this breach can be sleeved on the pipe needing welding by convenient this utility model.
This utility model is simple for structure, can directly be sleeved on tubular structure, be coordinated with multi-step by ladder-type structure, and the composite soldering that brazing solder and brazing flux mix is conducive to the direct soldering of this utility model, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the suction nozzle soldering of original compressor.
Fig. 2 is this utility model embodiment soldering places cross sectional representation.
Fig. 3 is this utility model embodiment solder longitudinal section.
Detailed description of the invention
Referring to Fig. 3, this utility model embodiment is the ring-type of hollow, and its cross section is stairstepping, there is small stair 1 and big step 2, between small stair 1 with conical pipe 4 shown in Fig. 2, suction pipe 5, step coordinates, and between big step 2 with conduit 3, conical pipe 4, step coordinates, thus completing welding better.
The present embodiment, by Powdered solder and brazing flux and binding agent mixing briquetting, utilizes mould pressurizing molding final vacuum dehydration precipitation, forms composite soldering, is processed into stairstepping solder.
This composite soldering is after pyrite brazing flux and solder are made one by a certain percentage, breach brazing flux painting in conventional brazing and add the step restriction to welding efficiency, reduce brazing temperature to a certain extent simultaneously, reduce the demand that the fusing point between pyrite brazing flux and solder is poor, substantially increase soldering efficiency and quality.Brazing flux is full and uniform with solder to be mixed, and can obtain the soldered fitting that joint performance is good, has that joint surface is smooth, intensity is high, have the advantages such as good mechanical performance.Use this solder can be made directly soldering, improve and add brazing flux and carry out the operator scheme of soldering, improve production efficiency, and be highly suitable for the disposable soldering of the many lamellar spacings of stairstepping.
The present embodiment advantage
1, strength of joint is high, and after adopting irony or steel mother metal, the intensity of soldering can reach 660MPa, and the intensity of copper mother metal only has 205MPa；
2, the irony of material same with housing or the air suction inner pipe of steel and outer tube can be adopted, and the reservoir bend pipe of irony or steel, greatly reduce the material cost of copper material.Analyzing from the copper valency of the Changjiang river non-ferrous metal net, the price of steel only has the 8% of copper valency；
3, owing to the material of reservoir bend pipe can be changed into steel pipe or iron pipe by copper pipe, it is possible to the welding procedure route of reduction reservoir, the connection of bend pipe and reservoir housing can with being connected in continuous tunnel furnace a soldering and complete of upper shell and lower house；
4, compared with the prior art, do not affecting on the basis installing and guaranteeing to connect firm, stable performance, it is not necessary to adding liquid or paste soldering flux, thus reducing cost of labor and material cost；
5, artificial welding confrontation amount can be reduced during operation and produce de-stabilising effect；
6 compare with existing molectron, copper facing part soldering processes, are absent from secondary and freeze and layers of copper comes off uneven hidden danger.
