Description
Technical field
The present invention is the swollen building mortion of upsetting and method of a kind of increase tee branch height, belongs to increase tee branch height
The swollen building mortion of upsetting and method innovative technology.
Background technology
Traditional three-way pipe（Fig. 1）It is most of to use casting, be welded to connect shaping and the making of expansion forming technique, extensive use
The fields such as chemical industry, daily life.In above-mentioned three kinds of manufacturing process, casting is forming technology the simplest, can obtain compared with
The tee pipe fitting of complicated and higher branch pipe, but the characteristics of due to casting technique itself, its be molded three-way pipe material therefor and into
Quality of item after shape, which is limited in certain scope, to be used；The technique for being welded to connect figuration manufacture three-way pipe is first in supervisor
Upper drilling, then by branch pipe welding to supervisor, forms three-way pipe.Relative to casting three-way plumber's skill, being welded to connect shaping should
High-quality tubing can be carried out being welded to connect shaping, and the height of branch pipe does not have any limitation, but the process program shortcoming be by
In perforate is again by branch pipe welding on supervisor on supervisor, the sealing wire of so supervisor and branch pipe is exactly that a complicated space is bent
Line, just because of the presence of space sealing wire, easily produces welding slag, hole in welding region, causes weld seam to be corroded, and causes leakage
Water problems occurs；In order to overcome the shortcoming of casting and welding tee pipe, branch is formed it into using inner high voltage is subject to straight-through tubing
The method of pipe can obtain the three-way pipe of monoblock type.Because inner high voltage formation three-way pipe is obtained by the method for Plastic Forming, institute
It is good with its quality, the deficiency that casting and welding method are brought to product quality is overcome, this is also much to use three-way pipe at present
Occasion wish apply expansion forming three-way pipe the reason for one of.Therefore the method for internal high pressure forming three-way pipeline is also closed
Note and attention.However, the method for existing use internal high pressure forming three-way pipe, due to forming branch pipe by inner high voltage in straight-through tubing
During generally branch pipe wall thickness it is thinning, cause the height by direct expansion forming three-way pipe branch pipe to be restricted, this is also serious
It has impact on the use of internal high pressure forming three-way pipe.Therefore, a kind of method that can improve shaping three-way pipe branch pipe height of research and development,
It is of great significance for obtaining higher-quality three-way pipe tool.
