Abstract
The utility model belongs to metal material processing field, more particularly to a kind of seamless aluminium tubing manufacturing device of core rod, a kind of seamless aluminium tubing manufacturing device of core rod, with extrusion die, it is equipped with extrusion die cavity in extrusion die, the extrusion die cavity side is connected with feed channel, the other side is equipped with extrusion chamber, plug channel is set below the extrusion chamber, high pressure stomata is equipped between the extrusion chamber and plug channel, one end of high pressure stomata is connected with inlet channel.The utility model will not damage the plug in aluminum pipe while completing the manufacture of seamless aluminium tubing, so that the application range of seamless aluminium tubing is wider, more have diversity.
Description
Technical field
The utility model belongs to metal material processing field, and in particular to a kind of seamless aluminium tubing manufacture dress of core rod
It sets.
Background technique
For seamless aluminium tubing due to being one-pass molding, tensile strength and elasticity modulus are much higher than conventional single-stage aluminum pipe, and are spreading
If when pipeline, conventional single-stage aluminum pipe since length is not enough so need to weld the common aluminum pipe of multistage, and weld due to
Use for a long time will lead to corrosion leakage, cause tremendous influence to the health of environment and people.And under different occasions, seamless aluminium tubing
It is inside frequently necessary to fill some other materials to make its rigidity or other performances touch the mark or generate some other functions
Effect, to expand its use scope.The molding mode of seamless aluminium tubing injects mandrel material using rigid hot extrusion molding
When, often due to plug bears not living high temperature and cause to influence plug reduced performance or even damage plug.
Utility model content
Technical problem to be solved by the utility model is: in view of the foregoing drawbacks, providing one kind at the time of molding will not be because of high temperature
And damage the seamless aluminium tubing manufacturing device of plug.
The utility model solves its technical problem the technical solution adopted is as follows: a kind of seamless aluminium tubing of core rod manufactures
Device has extrusion die, is equipped with extrusion die cavity in extrusion die, the extrusion die cavity side is connected with feed channel, and the other side is equipped with
Extrusion chamber, the extrusion chamber lower section are arranged plug channel, high pressure stomata, high pressure gas are equipped between the extrusion chamber and plug channel
The one end in hole is connected with inlet channel.Rigid hot aluminium is come out after squeezing from extrusion chamber, plug by being squeezed into extrusion die cavity
Injection, and formed together with aluminum pipe after extruding.High pressure stomata blows out high pressure gas, the shape between extrusion chamber exit and plug
The aluminium of higher temperature, is cooled to the temperature that will not damage plug by tapered high pressure air cavity.
It is further improved as the utility model, cooling chamber, cooling chamber and cooling water is equipped on the outside of the aluminium type chamber
Water filling port and cooling air gas injection port communicate.The design of cooling chamber is so that aluminium more fast cooling forms, to temperature requirement difference
When can freely select water cooling molding or air cooling molding.
The beneficial effects of the utility model are: will not be damaged in aluminum pipe while completing the manufacture of seamless aluminium tubing
Plug more has diversity so that the application range of seamless aluminium tubing is wider.
Detailed description of the invention
Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will
It becomes apparent.
Fig. 1 is the diagrammatic cross-section of the utility model；
Fig. 2 is the face the utility model C partial enlarged view.
Wherein: 1. extrusion dies, 2. extrusion die cavities, 3. feed channels, 4. extrusion chambers, 5. plug channels, 6. aluminum pipes, 7. high pressure gas
Hole, 8. high pressure air cavitys, 9. inlet channels, 10. cooling chambers, 11. cooling water water filling ports, 12. cooling air gas injection ports, 13. plugs.
Specific embodiment
It is enlightenment based on the following the desirable embodiment of the utility model, passes through following description, relevant staff
Completely various changes and amendments can be carried out in the range of without departing from this item utility model technical idea.This item is practical
Novel technical scope is not limited to the contents of the specification, it is necessary to determine that its is technical according to scope of the claims
Range.
The utility model is further detailed with reference to Fig. 1: a kind of seamless aluminium tubing manufacturing device of core rod, tool
There is extrusion die 1, be equipped with extrusion die cavity 2 in extrusion die 1,2 side of extrusion die cavity is connected with feed channel 3, and the other side, which is equipped with, to be squeezed
Chamber 4 is pressed, is inserted into plug channel 5 below the extrusion chamber.High pressure stomata 7 is equipped between the extrusion chamber 4 and plug channel 5, it is high
The calm the anger one end in hole 7 is connected with inlet channel 9.5 side of plug channel is equipped with cooling chamber 10, the cooling chamber 10 and cooling
Water water filling port 11 and cooling air gas injection port 12 communicate.
Rigid hot aluminium is come out after squeezing from extrusion chamber 4 by being squeezed into extrusion die cavity 2, and plug passes through plug channel 5
Injection, and formed together with aluminum pipe 6 after extruding, aluminum pipe 6 envelopes plug 5.High pressure stomata 7 blows out high pressure gas, is squeezing
Taper high pressure air cavity is formed between 4 exit of mould and plug 5, and the aluminium of higher temperature is cooled to the temperature that will not damage plug 5
Degree.Cooling water injects in cooling chamber 10 from cooling water water filling port 11, and aluminium more fast cooling is helped to form.
