本实用新型涉及一种锥形簧状钎料环，钎料环为细丝或薄窄带钎料绕制而成的轴向多环圈结构的锥形簧状钎料环，锥形簧状钎料环的锥度为1:10～1:2，且锥形簧状钎料环的小径端内径为2.0～56.0mm。本实用新型的簧状钎料环，小孔孔径可小于被焊管路的外径，以有效增加紧固力，起到良好的防滑、定位效果，有利于焊环自动化预装配的推广和应用，且本实用新型具有结构简单、生产效率高、成本低等优点，可更好应用于管路钎焊场合。

The utility model relates to a conical spring-shaped solder ring. The solder ring is a conical spring-shaped solder ring with an axial multi-ring structure wound by a thin wire or a thin strip of solder. The conical spring-shaped solder ring The taper of the material ring is 1:10 to 1:2, and the inner diameter of the small diameter end of the conical spring-shaped solder ring is 2.0 to 56.0 mm. In the spring-shaped solder ring of the utility model, the aperture of the small hole can be smaller than the outer diameter of the pipe to be welded, so as to effectively increase the fastening force, achieve good anti-skid and positioning effects, and is beneficial to the promotion and application of the automatic pre-assembly of the welding ring And the utility model has the advantages of simple structure, high production efficiency, low cost, etc., and can be better applied to pipeline brazing occasions.
