Description

Technical Field [0001] The present invention relates to a manufacturing method of a connector spring applicable to a pipe connector,

The present invention relates to a method of manufacturing a spring, and more particularly, to a method of manufacturing a connector spring applied to a piping connector for connecting a plurality of pipes.

Pipe Pipe Pipe is to connect the two pipes which are arranged through the wall. When connecting two pipes of different diameters, the part where the diameter difference occurs is filled with packing. Such pipe pipe packing is mainly used for transporting material through a pipe pipe in a ship or a structure having a fluid facility. The material transported through the pipe can be mainly water or oil, and other liquid substances, gases, and cables for various communications. Conventional pipe pipe packing has only the purpose of transporting the material between two pipes of different diameters, so it can not cope with noise and vibration between pipes when used in a ship or a building having fluidity facilities. There is a problem that the packing and the piping pipe are damaged.

No. 10-0474250 relates to a joint pipe for preventing noise used for pipe connection. The joint pipe is formed by spacing an inner pipe and an outer pipe so as to form an air layer, a closing ring is inserted and fixed at an end of the inner pipe, And the packing has a thin thin film tube of soft material formed on the inner diameter of the insertion tube portion, and the upper end of the packing is an outer diameter- And a nut is fastened to the male screw and the pressure ring is inserted into the nut and the lower end of the pressure wheel is formed with an inner inclined surface so as to be in close contact with the outer diametric surface of the packing. When the nut is tightened, the pressure roller presses the packing. The packing is brought into close contact with the outer diameter of the pipe, The packing is not biased to one side because the packing does not turn when the nut is tightened, and the air layer formed on the coupling pipe greatly improves the noise prevention performance and improves the heat insulating effect So that condensation can be prevented. However, the present invention differs from the above-described invention in that a shape of a spring desired by a user can be freely manufactured through the shape of a mandrel and a pressure member. Further, since the first and second leg portions of the connector spring according to the manufacturing method of the present invention are formed in a twisted shape spaced apart from each other by a distance of 5-30 °, the connector spring can be easily inserted .

There is a need for a manufacturing method of a connector spring that is mounted on a piping connector for connecting a plurality of conventional piping, in which the manufacturing process is simpler and the manufacturing is easy in the shape desired by the user.

The present invention provides a method of manufacturing a connector spring that is applied to a piping connector for connecting a plurality of pipes,

I) linearly machining a material to be used as a spring;

Ii) preparing a mandrel;

Iii) winding the machined spring wire material obliquely on the mandrel;

Iv) forming the mandrel with the spring wire wound thereon by applying pressure to the mandrel with a pressure member;

V) separating the molded spring from the mandrel;

Vi) cutting said separated spring;

The present invention provides a method of manufacturing a connector spring that is applied to a piping connector.

According to the manufacturing method of the connector spring applied to the piping connector of the present invention, the manufacturing process is relatively simple as compared with the conventional spring manufacturing method, and the shape of the spring desired by the user can be freely manufactured through the shape of the mandrel and the pressure member. Also, since the first leg portion and the second leg portion of the connector spring are spaced apart from each other by a distance of 5 to 30 degrees with respect to a plane perpendicular to the mandrel center axis, There are advantages to use.
