Abstract
The invention relates to a processing technique of titanium and titanium alloy section material and belongs to the technology field of metallic material processing. The processing technique includes the following main steps: (1) the material is bright-turned; (2) the material is coated with a layer of copper sheet; (3) the material is heated to the temperature of over 900 DEG C; (4) extrusion molding is carried out by an extrusion machine. The infusible materials of titanium and titanium alloy are molded by extrusion in the extrusion machine so that the material properties are obviously improved, thereby reducing the process frequency and obviously improving the economical benefit.
Description
Technical field
The invention belongs to the machining of metal material processing technical field, particularly titanium or titanium alloy.
Background technology
The section bar material section bar of titanium or titanium alloy forges processing by heating the back in the past and since the metallic character of titanium or titanium alloy in heating process with after gases such as hydrogen, oxygen in the air contacts, make burning easily, the hardness raising becomes fragile.The performance and the structure of metal itself in the power effect distortion of forging process China and foreign countries, have also been influenced.
Forging repeatedly to influence material property, and is difficult to control, and the air contact causes fragility to increase.
Summary of the invention
Provide a kind of section bar processing technology of titanium or titanium alloy during goal of the invention of the present invention, to overcome heating, to forge processing to the titanium effect of material performance.
Specifically, the section bar processing technology of titanium or titanium alloy, it is to implement according to following steps:
(1), by the design truck light that needs a person with the qualifications of a general;
(2), in material outsourcing one deck copper sheet protection, reduce the air contact and also play certain lubrication;
(3), be heated to more than 900 ℃;
(4), on extruder by the design moulding of helping out;
(5) reconditioning reprocessing
(6) finished product
Squeeze pressure is not less than 1000 tons in the above-mentioned steps (4).Extruder be 1000 tons with
Oil extrusion press or hydraulic extruder, the recipient temperature is the 300-600 degree.
The present invention is with the titanium or titanium alloy material, and through extruder, high warm-extrusion forming has increased tensile strength, and plasticity.Its performance significantly improves, and has reduced the processing number of times, and economic benefit obviously improves.Can be processed into as required flat, the garden, the side, Any shape such as pipe, the working (machining) efficiency height just can become finished product through simply processing.
Advantage of the present invention is to adopt extrusion process processing titanium or titanium alloy section bar it is subjected to equipment and place less-restrictive, can make all size titanium or titanium alloy section bar as required, reduces welding or need not weld, and satisfies the designing requirement of domestic titanium or titanium alloy section bar substantially.Titanium or titanium alloy section bar matter intensity after extruding increases, and physical property improves, and does not conceal and splits the flaw detection qualification rate height.
The specific embodiment
The section bar processing technology of titanium or titanium alloy, it is to implement according to following steps:
(1), stores van light;
(2), protect the contact of minimizing air at material outsourcing one deck copper sheet; Play certain lubrication;
(3), be heated to more than 900 ℃;
(4), extrusion molding as required on extruder.Squeeze pressure is not less than 1000 tons, and the recipient temperature is the 300-600 degree;
(5) reconditioning reprocessing;
(6) finished product.
Claims (2)
1, the section bar processing technology of titanium or titanium alloy is characterized in that implementing according to following steps:
(1), stores van light;
(2), in material outsourcing one deck copper sheet protection, reduce the air contact and also play certain lubrication;
(3), be heated to more than 900 ℃;
(4), extrusion molding on extruder;
(5) reconditioning reprocessing;
(6) finished product.
2, the section bar 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).
