Description

Technical Field [0001] The present invention relates to a branching apparatus for branch dispensing fluid of a fluid distribution branch,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch port forming apparatus for a fluid distributing branch, and more particularly, to a branch port forming apparatus for a fluid distributing branch which is capable of performing drilling and drawing operations in one apparatus.
Generally, the branching tube for distributing the fluid serves to distribute the hot water, the cold water or the heating medium circulating the branch tube to supply the fluid to various places so that the heating or cooling can be performed.
The fluid distribution branch includes a method of welding and mounting a socket to connect a plurality of branch tubes on a circumference of a main body, a method of drawing a hole drilled in the main body to form a screw in an expanded inner diameter A method has been proposed.
Meanwhile, Korean Patent Laid-Open No. 10-2000-0073194 (hereinafter referred to as "Prior Art Document 1") discloses a method of welding a socket, which is a former method, to a branch pipe and a method of manufacturing the hot water distributor for a hot water boiler "Was proposed.
In the method of manufacturing a hot water dispenser of the prior art document 1, a cylindrical distribution pipe having a predetermined length is formed by a drawing process, one side of the circumferential surface forms a first horizontal surface of a predetermined width in the longitudinal direction, Wherein the main surface is formed by a cylinder having a second horizontal surface having a width wider than the first horizontal surface and having a surface on which the two circumferential surfaces of the opposing surfaces are flat and on the surface of the first horizontal surface and the second horizontal surface of the distribution pipe, And the inserted length is inserted to a flange portion formed on one side of the socket, and an annular type welding electrode is inserted between the inlet hole and the branch hole and the flange portion of the socket, And then heat is applied thereto so that the annular electrode is melted and welded.
The manufacturing method of the cylindrical distribution pipe fabricated as described above is that the socket is easily installed because a part of the circumferential surface is flattened and welding is performed with the annular welding rod interposed therebetween, , There is a problem that the socket mounted depending on the welded portion easily cracks during use and causes leakage.
A method for forming a hole in the inner diameter of the hole by drilling a hole in the body, which is the latter method, is disclosed in Korean Patent Laid-Open No. 10-2003-0039102 (hereinafter referred to as "Prior Art Document 2" In the "Pipe manufactured by the method of manufacturing a pipe for welding fluid without welds and the bonsai pipe and the pipe manufactured by the manufacturing method" proposed by the present invention, a technique of extending a metal ball through a hole drilled in a wave- In the "method for manufacturing a branch port of a pipe for distributing fluid" proposed in Patent Document 10-0670591 (hereinafter referred to as " Prior Art Document 3 "), a hole drilled in a pipe for distributing fluid is dilated as a tee- .
The methods disclosed in the prior art documents 2 and 3 are a method of forming a thread in an inner diameter after expanding a small hole drilled in a pipe, in which a screw is directly formed in the expanded portion, In order to form a thread on the expanded part, the thickness of the material must be thick to form the thread and the bottom of the screw. Therefore, to expose it as a ball or tee (T) drawing tool and a drill, A troublesome process requiring a fusing drilling operation to provide a firing temperature is required, and when the thickness of the distribution pipe is made thin to facilitate expansion, a tearing portion occurs in the manufacturing process, resulting in a large amount of defects, There is a problem that the raw material cost is increased.
Also, holes are drilled in order to weld the sockets to connect the branches, or to form the screw on the expanded part to connect the branch directly. The formation of the holes into which the sockets are inserted or the holes for the expansion are generally drilled one by one or simultaneously with drills. When the hole is drilled through the drilling, the thicker the material, the better the workability. However, when it is thin, the cutting part hangs on the spiral blade edge and the cutting part is bent or widened, so that the desired shape can not be obtained. Burrs are generated irrespective of the thickness of the material, and the burrs generated in the processing using the drill tool are irregular, and there is a problem that the continuous operation is difficult because it is rough enough to cause troubles in the post-work.
In the prior art, Korean Patent No. 10-1095954 (hereinafter referred to as "Prior Art Document 4") discloses a "apparatus for manufacturing a fluid distribution branching apparatus" for overcoming the disadvantages of the prior art documents 1, .
In the manufacturing apparatus proposed in the prior art document 4, the pipe main body in the form of a pipe for distributing the fluid is cut to a predetermined length, a large number of holes for inflow or discharge are formed around the main body of the pipe, And the lower end of the socket is inserted and fixed in the inner diameter of the flange after the socket is projected while expanding the inner diameter of the flange from the inside of the branch main body, A technique for manufacturing a fluid distribution branch through a process of brazing and welding a contact portion of a socket has been disclosed.
However, in the process of forming the connection port in the branch pipe for connecting the sockets in the prior art document 4, the process of perforating the hole in the branch pipe and the process of pulling the flange of the hole to the outside of the branch pipe are separately performed And most of the holes are drilled into the garden. When the holes of the garden are pulled out, the shape of the flange is shaped like an egg shape, That is, since it is formed to be curved in an egg shape, there is a problem that the weldability of the socket is poor.
The above description of the apparatus for manufacturing a fluid distribution branch and the manufacturing method thereof is described in detail in the following prior art documents, so that a detailed description thereof will be omitted.
