Description
Technical field
The present invention relates to mechanical manufacturing field, swollen combined shaping method is rolled in more particularly to a kind of double branch pipe upsetting side by side.
Background technology
Double branch pipe is widely used in the pipe-line system in the fields such as air-conditioning, automobile and petrochemical industry side by side, plays and catchments, shunts
Important function.According to the Service Environment of double branch pipe side by side, it is necessary to meet uniform wall thickness, not easy to crack and branch pipe highly it is high will
Ask.At present casting, welding and bulging be double branch pipe side by side main forming and machining method, but existing defects：1) casting processing
Double branch pipe side by side, the characteristics of due to casting technique itself, easily produces the tissue such as shrinkage cavity and shrinkage porosite, coarse grains and segregation and lacks
Fall into, cause molded article quality low；2) welding forming double branch pipe side by side, branch pipe is highly unrestricted but easy in welding region
Welding slag, hole are produced, causes weld seam to be corroded, causes the problems such as leak, oil leak to occur；3) in order to obtain monoblock type double branch side by side
Pipe, carries out double branch pipe side by side using internal high pressure forming technique and shapes, increasingly receive significant attention and apply, but tubing is in shaping
During be responsible for end upsetting, influenceed by factors such as material property, frictions, material is difficult to flow to branch pipe from supervisor, branch pipe it
Between material be difficult to supply cause branch thickness of pipe wall too early be thinned and produce rupture so that branch pipe forming height is limited, simultaneously as axle
The problems such as corrugation and too early rupture is not produced at that time, easily to feeding and internal pressure processing parameter matching.Therefore, research one kind can
Improve tube wall thickness uniformity, improve double branch pipe height side by side and the method for preventing corrugation from occurring, to obtain good quality and
Arrange double branch pipe and realize that its monoblock type is formed with highly important engineering significance.
The content of the invention
It is an object of the invention to overcome shortcoming present in prior art there is provided a kind of forming quality is good, uniform wall thickness,
Swollen compound molding device is rolled in the branch pipe highly high upsetting of double branch pipe side by side.
Another object of the present invention is to provide a kind of double branch pipe upsetting side by side to roll over swollen combined shaping method.
The purpose of the present invention is achieved through the following technical solutions：
Swollen compound molding device is rolled in a kind of double branch pipe upsetting side by side, including motor 1, key 2, travelling gear 3, key 4, left axle are to punching
