Description
Technical field
The present invention is a kind of double branch pipe internal high pressure forming device and method arranged side by side, belongs to double branch pipe internal high pressure forming dress arranged side by side
Put and method innovative technology.
Background technology
Traditional double branch pipe side by side（Fig. 1）It is most of to use casting, be welded to connect shaping and the making of expansion forming technique, extensively
Using fields such as chemical industry, daily lifes.In above-mentioned three kinds of manufacturing process, casting is forming technology the simplest, can be obtained
More complicated and higher branch pipe double branch pipe part arranged side by side, but the characteristics of due to casting technique itself, it is molded double branch pipe institute arranged side by side
It is limited in the quality of item after material and shaping in certain scope and is used；It is welded to connect figuration manufacture double branch pipe arranged side by side
Technique be first to be drilled on supervisor, then by branch pipe welding to supervisor, form double branch pipe arranged side by side.It is double side by side relative to casting
Branch pipe technology, being welded to connect shaping, this can carry out being welded to connect shaping to high-quality tubing, and the height of branch pipe does not have any limitation,
But the shortcoming of the process program is so welding of supervisor and branch pipe because perforate is again by branch pipe welding on supervisor on supervisor
Line is exactly a complicated space curve, and just because of the presence of space sealing wire, welding slag, hole are easily produced in welding region
Hole, causes weld seam to be corroded, and causes seepy question；In order to overcome casting and weld the shortcoming of double branch pipe arranged side by side, using pair
Straight-through tubing is subject to inner high voltage and forms it into the method for branch pipe that the double branch pipe arranged side by side of monoblock type can be obtained.Due to inner high voltage formation simultaneously
Row double branch pipe is obtained by the method for Plastic Forming, so its quality is good, overcomes casting and welding method to product quality
The deficiency brought, this is also the reason for much wishing double branch pipe arranged side by side using expansion forming using the occasion of double branch pipe arranged side by side at present
One of.Therefore the method in internal high pressure forming double branch pipe road arranged side by side is also attracted attention and is paid attention to.However, existing use inner high voltage into
The method of shape double branch pipe arranged side by side, because the wall thickness of the generally branch pipe during tubing is led directly to by inner high voltage formation branch pipe is thinning,
The height by direct expansion forming double branch pipe arranged side by side is caused to be restricted, this has also had a strong impact on internal high pressure forming double branch pipe arranged side by side
Use.Therefore, a kind of method that can improve shaping double branch pipe height arranged side by side of research and development, higher-quality side by side for acquisition
Double branch pipe tool is of great significance.
