Abstract
The utility model discloses a winding tool of gold based filiform brazing alloy. The winding tool of the gold based filiform brazing alloy comprises a forming mandrel, a rocker and a support, wherein the forming mandrel comprises two sections of step type mandrels with different diameters; the diameter of one section is equal to the diameter of a part to be welded and the diameter of the other section is 0.6 to 0.8 time of the diameter of the part to be welded; small holes which are used for fixing the filiform brazing alloy in the winding process are formed at two ends of the forming mandrel; the two ends of the forming mandrel are supported by the support through a bearing; and the rocker is connected with one end of the forming mandrel to provide rotary torsion of the forming mandrel. The winding tool of the gold based filiform brazing alloy has the advantages of enabling wound annular-shaped brazing alloy to match with parts by utilizing self-elasticity without needing other locating methods, guaranteeing stable welding quality of parts, being consistent in use amount of the brazing alloy, avoiding wastes caused by unreasonable use amount of the brazing alloy and being applicable to produce in quantity.
Description
Technical field
The utility model relates to solder winding technology field, is specially a kind of auri brazing wire coiling instrument.
Background technology
China uses auri solder HBAu82Ni to weld by vacuum brazing technique in the manufacturing welding of a plurality of machine aero-engine fuel nozzles.Because fuel nozzle welding point quantity is many, and size differs, the required solder amount of vacuum brazing is differed larger, the HBAu82Ni solder is expensive simultaneously, how to control the solder consumption well to save production cost when guaranteeing brazing quality, be the problem of solution that needs in the aero-engine production process.
Summary of the invention
The technical problem that solves
The purpose of this utility model is to provide a kind of thread auri solder that can the coiling different-diameter, and accurately controls the coiling instrument of auri solder use amount.
Technical scheme
The technical solution of the utility model is:
Described a kind of auri brazing wire coiling instrument is characterized in that: be comprised of forming core rod, rocking bar and bearing; Wherein forming core rod is two sections step plugs that diameter is different, wherein one section diameter equals the diameter of part to be welded, another section diameter equals 0.6～0.8 times of diameter of part to be welded, and there is aperture at forming core rod two ends, is used for fixedly brazing wire of winding process; The forming core rod two ends are arranged on bearing by bearing; Rocking bar is connected with forming core rod one end, and the driving torque of forming core rod is provided.
Beneficial effect
In this instrument, forming core rod is divided into two sections, wherein one section is used for the solder ring that coiling is consistent with part, after determining required solder ring size, recycle another the section with solder around making the assembling required diameter, because thread auri solder has good elasticity, solder around after making certain diameter, just can be utilized the elasticity of solder ring self, realize with part between tightness coordinate, save unnecessary and some positioning process that in particular cases can't realize.So being ring-type solder that on the one hand coiling goes out, the advantage of this instrument utilize self elasticity to coordinate with part, need not rely on other localization method, solder use amount high conformity on the other hand, guaranteed to guarantee the stay-in-grade while of weld parts, avoid the unreasonable waste that causes of solder consumption, be applicable to batch production.
Description of drawings
Fig. 1: structural representation of the present utility model;
Wherein, 1, bearing; 2, forming core rod; 3, rocking bar.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described:
With reference to accompanying drawing 1, the auri brazing wire coiling instrument in the present embodiment is comprised of forming core rod 2, rocking bar 3 and bearing 1. and wherein forming core rod is A, the different step plug of two sections diameters of B, and forming core rod two ends are arranged on bearing by bearing.Plug A section diameter is identical with diameter of part to be welded, is used for the solder ring of coiling part required diameter; Plug B section diameter is according to the experience that sums up in a large amount of practical operations, get the diameter of part to be welded of 0.6～0.8 times, be that accessory size is when being Φ D, the diameter of mandrel of B section is 0.6 Φ D～0.8 Φ D, the solder ring that goes out according to this diameter coiling, both guaranteed that the solder ring can utilize the elasticity of self to coordinate with part, guaranteed again that curvature between the two differed not too large, and made the solder ring be wrapped on part and whole the applying well.The diameter of mandrel of getting the B section in the present embodiment is 0.6 Φ D.The forming core rod two ends are drilled with the aperture than brazing wire slightly larger in diameter, are used for fixedly brazing wire of winding process.The bearing Main Function is fixed-type plug, is positioned on workbench as required in use to get final product.Rocking bar is welded on forming core rod one end, can guarantee to provide in use procedure enough moments of torsion and not loosening.
Use step of the present utility model is: the first step, brazing wire is wrapped on plug A section, and be wound around tightness and guarantee that brazing wire and plug are fully sturdy; Second step under brazing wire tightly is wrapped in state on plug, prolongs axially with scriber and draws a straight line on solder, determines the size of single solder ring with this, after determining that line is clear, unclamps brazing wire; The 3rd step, with plug B section, brazing wire is carried out the secondary coiling, require identically with the first step, need assurance winding tightness guarantee that brazing wire and plug are fully sturdy.The solder that uses the coiling of B section plug to complete, the indentation that stays to the layout line is cut into single solder ring with solder and gets final product.
