Abstract
The invention belongs to an extrusion processing process for section materials of titanium and titanium alloy in the technical field of metal material processing, which mainly comprises the steps as follows: the material is machined; glass powder is diluted and evenly coats processing mother material, and the mother material is heated up to a processing temperature to be processed or the mother material is heated up above 900 DEG C, and then the glass powder evenly coats and is processed; the extrusion molding is performed on an extruder. After the mother material is heated, a glass lubricant at a solid state is evenly attached to the mother material in the passing form. The glass lubricant serves the functions of lubricating, preventing oxidation and protecting the surface of the metal material, can be applied to other metal materials processed through the heating of the extruder, and can be further applied to a protective layer for preventing the oxidation in the forging process of the metal material. In the invention, the titanium, the titanium alloy and other metal materials processed through the heating of the extruder is extruded and formed through the extruder, thereby greatly reducing the cost and improving the economic benefits obviously; inexpensive glass powder is adopted as the lubricant rather than the metal lubricant, so that the mother material cannot be contaminated and the surface quality of the section material can be improved.
Description
Technical field
The invention belongs to the machining of metal material processing technical field, particularly non-ferrous metal.
Background technology
In the shape mechanical processing process, forging is general means, at present titanium or titanium alloy is still adopted these conventional meanses.Have and the diverse characteristics of material such as iron and steel but titanium or titanium alloy is raw-material.Adopt to forge repeatedly to change material property, the air contact causes fragility to increase, and is bigger to the performance impact of material.
Make the titanium or titanium alloy section bar by the extruding of kiloton extruder and become preferred means.What pushed the use of titanium or titanium alloy section bar is metallic lubricant in the past, and the copper coin of bag thickness 1mm or bag corrosion resistant plate on masterbatch outer surface and inner surface to reduce the wearing and tearing of titanium material to mould, increase materials processing forming materials rate.Situations such as this way all has very big wearing and tearing to mould and rapidoprint itself, causes reduce die life, and the rapidoprint surface quality is poor, and loss increases, and processing dimension is undesirable.Take down simultaneously when remaining in surperficial copper coin or corrosion resistant plate, need pickling, caused environmental pollution.If pickling is not thorough, also can cause the pollution of masterbatch, form hidden danger.
Summary of the invention
Provide a kind of processing technology of using glass dust as the section bar special lubricant for squeezing of titanium or titanium alloy during goal of the invention of the present invention,, raise the efficiency, reduce production cost significantly to overcome metallic lubricant influence to material in process.Glass lubricant plays lubricated, and is anti-oxidation, and the effect of protective money metal surface and mould fundamentally solves the difficult problem that the rapidoprint quality does not pass a test, and has reduced processing link.
This patent can be applicable to other metal material that adds hot-working by extruder.
This patent can also be applied to the protection against oxidation layer in the metal material forging process simultaneously.
Specifically, use the production technology of glass dust as titanium or titanium alloy section bar special lubricant for squeezing, it is to implement according to following steps:
(1) stores van light;
(2) the glass dust dilution is evenly spread upon on the processing masterbatch, then masterbatch is heated to processing temperature and processes or masterbatch is heated to more than 900 ℃, then glass dust is evenly smeared processing; Or
(3) also can be after the masterbatch heating with glass lubricant with solid-state form by the form of passing evenly attached on the masterbatch.
(4) extrusion molding or forging molding on extruder.
Squeeze pressure is not less than 1000 tons in the above-mentioned steps (4).
The present invention is with titanium or titanium alloy and other is by the mach metal material of extruding, through extruder, extrusion molding, its performance obviously improves, and uses the glass lubricant production cost obviously to descend, and economic benefit significantly improves, simultaneously, the present invention adopts inexpensive glass powder as lubricant rather than use metallic lubricant, can not cause masterbatch to pollute, and has improved the section bar surface quality.
The specific embodiment
The section bar extrusion-processing technology of titanium or titanium alloy, it is to implement according to following steps:
(1) stores van light;
(2) the glass dust dilution is evenly spread upon on the processing masterbatch, then masterbatch is heated to processing temperature and processes or processing masterbatch is heated to more than 900 ℃, then glass dust is evenly smeared processing; Or
(3) also can be after the masterbatch heating with glass lubricant with solid-state form by the form of passing evenly attached on the masterbatch.
(4) extrusion molding or forging molding on extruder.Squeeze pressure is not less than 500 tons.
Among the present invention glass lubricant play lubricated, anti-oxidation, the effect of protective money metal surface.The inventive method can be applicable to other metal material that adds hot-working by extruder.Can also be applied to the protection against oxidation layer in the metal material forging process.
Claims (2)
1, the section bar extrusion-processing technology of titanium or titanium alloy is characterized in that implementing according to following steps:
(1), stores van light;
(2) the glass dust dilution is evenly spread upon on the processing masterbatch, then masterbatch is heated to processing temperature and processes or processing masterbatch is heated to more than 900 ℃, then glass dust is evenly smeared processing; Or
(3) also can be after the masterbatch heating with glass lubricant with solid-state form by the form of passing evenly attached on the masterbatch.
(4), extrusion molding or forging molding on extruder.
2, the section bar extrusion-processing technology of titanium or titanium alloy according to claim 1 is characterized in that squeeze pressure is not less than 1000 tons in the step (4).
