Description
Technical field
The present invention relates to a kind of processing molding method of threeway, in particular to a kind of forming method of pure nickel threeway.
Background technique
Pure nickel has excellent corrosion resistance, especially resistance to alkali corrosion, therefore is widely used in alkali chemical plant installations；But it is pure
Nickel hardness is very low.
Traditional hydroforming is will to inject liquid in the pipe equal with threeway diameter, passes through two levels of hydraulic press
Side cylinder synchronous centering moves extrusion tube blank, and volume becomes smaller after pipe is squeezed, and the liquid in pipe becomes smaller with pipe volume and pressed
Power increase, when reaching pressure required for tee branch expansion, metal material in side cylinder and pipe fluid pressure it is dual
It is flowed and expansion branch pipe under effect along mold inner-cavity.
Pressure conduction medium therein is hydraulic oil, using hydraulic oil as pressure conduction medium, in forming process very
Corrugation is easy to appear so as to cause scrap of the product, product cost is greatly improved, extends the product delivery cycle.
Summary of the invention
It prevents corrugation when molding in view of the deficiencies of the prior art, the present invention provides a kind of, improve product quality
The forming method of pure nickel threeway.
To achieve the above object, the present invention provides the following technical scheme that a kind of pure nickel threeway
Forming method, which is characterized in that steps are as follows: a, selecting raw material, is greater than the jumping-up hole depth and diameter using length
Tubular blank identical with the jumping-up hole is as raw material；It b, can consolidating with pressure distortion by injection in the tubular blank of step a
State particle；C, the rodlike blank that river sand is injected in step b is put into molding die implements upset, i.e., tubular blank is upset place
Diameter increase, promote the cross section of tubular blank in T-shaped；D, upset tubular blank will be completed in step c to be put into
The intracavitary implementation sizing of the type of pattern tool, forms tee tube.
By adopting the above technical scheme, by the raw material (tubular blank) addition for pressure conduction can be with pressure distortion
Solid granulates, the solid granulates on the one hand pressure needed for deformation of products when can reach molding, on the other hand in extrusion process
It can play a supporting role to tubular blank, to guarantee that tee tube will not wrinkle in processing, ensure that the processing matter of tee tube
Amount, prevents waste product from generating, not only increases processing efficiency, and also avoid generating waste product and the production of production cost that occurs
It is raw.
The present invention is further arranged to: solid granulates are river sand.
By adopting the above technical scheme, river sand easily collecting, and it is cheap, and it is in tubular blank with preferable
Mobility and supportive.
The present invention is further set to: can be coated with anti oxidation layer in threeway pipe surface after the completion of step d.
Wherein, anti oxidation layer is boron oxide layer.
By adopting the above technical scheme, setting can extend the service life of tee tube in this way, further play it is anti-oxidant,
Corrosion resistant effect.
Specific embodiment
The present invention provides a kind of forming methods of pure nickel threeway, and steps are as follows: a, choosing
With raw material, the jumping-up hole depth and diameter tubular blank identical with the jumping-up hole are greater than as former using length
Material；It b, can be with the solid granulates of pressure distortion by injection in the tubular blank of step a；C, the rodlike of river sand will be injected in step b
Blank be put into molding die implement it is upset, i.e., tubular blank be upset place diameter increase, promote the cross section of tubular blank
In T-shaped；D, the intracavitary implementation of type for completing upset tubular blank in step c and being put into molding die is formed, forms threeway
Pipe.By in the raw material (tubular blank) addition for pressure conduction can be with the solid granulates of pressure distortion, the solid granulates
On the other hand pressure needed for deformation of products when on the one hand can reach molding can play support to tubular blank in extrusion process and make
With, thus guarantee tee tube processing when will not wrinkle, ensure that the processing quality of tee tube, prevent waste product from generating, not only mention
High processing efficiency, and also avoid generating waste product and the generation of production cost that occurs.The preferred river of solid granulates therein
Sand, preferably river sand be due to its easily collecting, it is and cheap, and it is in tubular blank and has preferable mobility and prop up
Support property.
In order to further improve inoxidizability and corrosion resistance of the invention, threeway pipe surface is coated with anti oxidation layer.It should
Anti oxidation layer is preferably boron oxide layer.
