Description

Adapter manufacturing method for pipe connection {METHOD FOR MANUFACTURING ADAPTOR FOR CONNECTING PIPE}

The present invention relates to a method for manufacturing an adapter for pipe connection, and more particularly, the outer diameter of the outward flange is larger than the inner diameter of the inward flange in a state in which the outward flange is put into the inward flange and the main and nut connectors are assembled. The present invention relates to an adapter manufacturing method for pipe connection that can extend the plumbing pipe so that the inward flange can be easily spread on the outward flange so that the nut connector is not detached from the main connector and maximize the productivity and assembly.

In general, the pipe connection adapter is a part connecting the main pipe (P1) and the sub-pipe (P2) so that the fluid or gas flow from the main pipe (P1) to the sub pipe (P2).

1 is a perspective view showing a pipe connection adapter according to the prior art, Figure 2 is an exploded perspective view showing a pipe connection adapter according to the prior art, Figure 3 is a cross-sectional view showing a pipe connection adapter according to the prior art.

Adapter for pipe connection according to the prior art is composed of the main connector 10 and the nut connector 20 as shown in Figs.

The main connection body 10 is formed with one side body 11 having a main screw groove 11a for receiving and screwing the main pipe P1 and integrally extending from the one side body 11 to form an outward flange 12a. At the same time, the other side body 12 is provided with a pipe 12b.

The nut connector 20 has an inward flange 21 having an inner diameter larger than the outer diameter of the outward flange 12a of the main connector 10 and at the same time receives a sub pipe P2 to screw the sub screw groove. (22) is provided.

Adapter manufacturing method for a pipe connection according to the prior art is to put the outward flange (12a) into the inward flange (21) to assemble so that the nut connector 20 is fitted into the main connector (10) from the outward flange (12a) The ring spring 30 is elastically pushed under the outward flange 12a by pushing the ring spring 30 between the outer diameter of the outward flange 12a and the inner diameter of the nut connector 20 so that the inward flange 21 does not come out. It will go through a process to be seated.

The ring spring 30 has a smaller inner diameter than the outer diameter of the other body 12 and is larger than the thickness of the outward flange 12a so that the ring spring 30 is elastically seated directly under the outward flange 12a. While tightly adhered to the outer circumference of the) it is possible to take an outer diameter larger than the inner diameter of the inward flange 21 of the nut connector 20 consequently the inward flange 21 of the nut connector 20 is a ring-shaped spring ( 30) to avoid getting caught.

By the way, the adapter for the pipe connection according to the prior art, but the ring-type spring 30 should be elastically seated directly under the outward flange 12a, but between the outer diameter of the outward flange 12a and the inner diameter of the nut connector 20. When the ring-type spring 30 is pushed into the invisible space of the cylinder, the ring-type spring 30 cannot be precisely positioned, and thus the tightening of the nut connector 20 which is screwed with the sub-pipe P2 is not secured. There is a problem that causes leakage of gas.

In addition, the ring-shaped spring 30 must be separately provided in addition to the main connector 10 and the nut connector 20, which greatly reduces productivity and assembly.

It is an object of the present invention to extend the plumbing pipe so that the outer diameter of the outward flange is larger than the inner diameter of the inward flange while putting the outward flange into the inward flange and assembling the main connector and the nut connector. The present invention provides a method for manufacturing an adapter for pipe connection that can not only prevent the nut connector from being separated from the main connector, but also maximize productivity and assembly.

Adapter manufacturing method for pipe connection according to the present invention for achieving the above object,

Providing a main body having one side body having a main screw groove for receiving and screwing the main pipe together with a main body having an outward flange while being integrally formed from the one side body, and having the other side body with a pipe hole;

Providing a nut connecting body having an inward flange having an inner diameter larger than an outer diameter of the outward flange and having a sub screw groove for receiving and screwing the sub pipes;

Inserting the outward flange into the inward flange and fitting the nut connector to the main connector;

And extending the plumbing hole such that the outer diameter of the outward flange is larger than the inner diameter of the inward flange.

The present invention simply puts the outward flange into the inward flange by expanding the plumbing pipe so that the outer diameter of the outward flange is larger than the inner diameter of the inward flange while the main connector and the nut connector are assembled. It is possible to prevent the nut from being separated from the main connector as well as to maximize the productivity and assembly is effective.

The present invention has the effect that can be produced more quickly according to the automated process by expanding the pipe is pushed into the tapered expansion rod connected to the piston of the hydraulic cylinder.

The present invention has an effect that can be expanded more easily and quickly by allowing the plumber to expand in the heated state.

A preferred embodiment of the adapter for pipe connection according to the present invention will be described with reference to the drawings, there may be a plurality of such embodiments, through the embodiments further objects, features and advantages of the present invention I can understand well.

4A to 4D are process diagrams illustrating a method for manufacturing a pipe connection adapter according to the present invention, and FIG. 5 is a cross-sectional view showing a pipe connection adapter according to the present invention.

Adapter manufacturing method for pipe connection according to the invention from the one side body 11 and the one side body 11 having a main screw groove (11a) for receiving and screwing the main pipe (P1) as shown in Figure 4a The main connection body 10 having the other side body 12 having the outward flange 12a and having the pipe hole 12b bored at the same time is formed integrally extending.

And, as shown in Figure 4b has an inward flange 21 having an inner diameter larger than the outer diameter of the outward flange 12a and at the same time has a sub-screw groove 22 for receiving and screwing the sub pipe (P2). One nut connector 20 is provided.

Subsequently, as shown in FIG. 4C, the outward flange 12a is inserted into the inward flange 21 to assemble the nut connector 20 to the main connector 10.

Next, as shown in FIG. 4D, the pipe 12b is expanded so that the outer diameter of the outward flange 12a is larger than the inner diameter of the inward flange 21.

As described above, in the method of manufacturing an adapter for pipe connection according to the present invention, the outward flange 12a is inserted into the inward flange 21 and the main connector 10 and the nut connector 20 are assembled together. By extending the piping hole 12b so that the outer diameter of the inner diameter is larger than the inner diameter of the inward flange 21, the inward flange 21 can be simply caught on the outward flange 12a so that the nut connection from the main connector 10 can be made. Not only can the sieve 20 be detached but also maximizes productivity and assembly.

Preferably, the pipe 12b is pushed into the tapered expansion rod (B) connected to the piston (P) of the hydraulic cylinder (S) to be expanded to enable faster production according to the automated process.

In addition, the piping 12b is to be expanded in a heated state to realize a quick expansion state, and furthermore, the heating temperature is 50 ~ 80 ℃ in consideration of the overall deformation in the case of synthetic resin and in the case of metal material considering the speed of work To 200-300 ° C.

The present invention can be used in the industrial field connecting the main pipe and the sub pipe so that the fluid or gas flow from the main pipe to the sub pipe.
