[0002] The high-pressure thermal compression tee is mainly used for the core pipe fittings in the header of the power generation boiler, which can facilitate the use and construction of the pipe. However, the size of the tee is traditionally the same. The method of installing different diameter joints achieves the purpose of shrinking, but the shrinking tee obtained by this method has many unstable factors and the safety factor is low

Embodiment Construction
[0019] As shown in the figure, a shrinking tee processing mold includes a mold upper tire 1 and a mold lower tire 2. The cavity formed after the mold upper tire 1 and the mold lower tire 2 are combined is the main pipe 4 of the mould, and the main pipe 4 is two The inner wall of the end is respectively provided with a shrinking die 3, and the said shrinking die 3 is composed of two semicircular arc surfaces symmetrically arranged on the inner walls of the upper tire 1 of the mold and the inner wall of the lower tire 2 of the mold. The inner diameter of the arc surface gradually decreases from one end to the other end, the end with a larger inner diameter is arranged at the nozzle of the main pipe 4, and the end with a smaller inner diameter is close to the center of the main pipe 4; Heavy hole 5.
[0020] The method for processing the tee by using the described shrinking tee processing mold comprises the following steps:
[0021] Step 1. Select a forged thick-walled seamless ...

A shrinking tee processing mold, including a mold upper tire and a mold lower tire, the cavity formed after the mold upper tire and the mold lower tire are combined is the main pipe of the mould, and the inner walls of the two ends of the main pipe are respectively provided with shrinking molds. The shrinking die described above is composed of two semicircular arc surfaces symmetrically arranged on the inner walls of both ends of the mold upper tire and the mold lower tire. The inner diameter of the semicircular arc surface gradually decreases from one end to the other end, and the inner diameter is larger. One end of the pipe is arranged on the nozzle of the main pipe, and the end with a smaller inner diameter is close to the center of the main pipe. A plurality of lightening holes are arranged on the top of the upper tire of the mold. Beneficial effects of the present invention: use the processing mold of the present invention to process the shrinking tee instead of the previous technology of adding different diameter joints, reduce unstable factors, enhance the safety factor of pipe fittings, and make the connection effect more convenient, safer and more efficient. Stablize.
Description
technical field [0001] The invention relates to a tee processing mold and a processing technology, in particular to a shrinking tee processing mold and a method for processing a tee using the mold. Background technique [0002] The high-pressure thermal compression tee is mainly used for the core pipe fittings in the header of the power generation boiler, which can facilitate the use and construction of the pipe. However, the size of the tee is traditionally the same. The method of installing different-diameter joints achieves the purpose of shrinking, but the shrinking tee obtained by this method has many unstable factors and the safety factor is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shrinking tee processing mold and a method for processing the tee using the mold, which can solve the unstable factors of adding different diameter joints at present, enhance the use safety factor of pipe fittings, ...
