Abstract
The invention discloses a pure titanium pipe extrusion process using a novel lubricating manner. The pure titanium pipe extrusion process comprises preprocessing a pipe blank, spraying glass powder, heating and extruding. The pure titanium pipe extrusion process using the glass powder lubricating manner has the advantages that the process is simple, environment pollution caused by the subsequent copper sheet pickling in a method using copper sheathing for lubricating is avoided, special equipment is not needed, low production cost is achieved, yield can be increased by about 6%, industrial production can be achieved easily, and a produced pipe is good in surface quality.
Description
Technical field
The invention belongs to metal pipe material pressure processing technology field is and in particular to arrive a kind of the pure of use novel lubricating mode
Titanium tube extrusion process.
Background technology
Because titanium or titanium alloy has low-density, Gao Biqiang, high temperature resistant, corrosion-resistant, no excellent comprehensive such as magnetic, bio-compatible
Close performance, enjoy the favor of every profession and trade, the particularly industry such as Aero-Space, ship ocean and chemical industry metallurgical, be applied to titanium width
Pipe, for manufacturing housing, pipeline, heat exchanger etc..
At present, the processing of titanium or titanium alloy seamless pipe is all using cold rolling vacuum annealing process.Generally pipe preparation is using brill
Hole extruding, plate (carrying) welding and three kinds of techniques of roll piercing, the unsuitable production specification of plate (carrying) welding production mode is many and batch is few
Product, weld seam is the weak place of comparison, relatively difficult during weld cleaning, and the method has that production efficiency is high, cost simultaneously
The advantages of low, wall thickness is more uniform, inner surface quality is good, the equipment of tubing that is can producing major diameter, input is simple.
The roll piercing mode of production is not very flexible, and product is more single, nor prepares the thin pipe of wall, the pipe obtaining
Base is not also oversize, but the method metal consumption is little, and equipment investment is few, without jacket and lubrication, free from environmental pollution, mould consumption
Few, high yield rate, processing cost low so as to be applied in titanium alloy pipe produces.
And the deflection of pressing method of holing is big, crystal grain is little, pipe uniform wall thickness, can be used for preparing the relatively thin pipe of wall thickness
Base.Extrude and generally adopt jacket lubrication, jacket lubrication can obtain preferable pipe surface, but sheath material consumption is larger,
More for removing jacket consumption acid ratio, also easily cause environmental pollution, its aided process is relatively more, and workload is big.
Content of the invention
For above-mentioned the deficiencies in the prior art, the present invention provides a kind of environmental pollution little, and lumber recovery is high, and manufacture method is simple
Pure titanium tube extrusion process.
The technical solution used in the present invention is:
A kind of pure titanium tube extrusion process of use novel lubricating mode, comprises the steps:
Step one, surface defect and the pre-heat treatment are carried out to titanium pipe blank；
Step 2, glass dust is sprayed into the inner surface of pipe described in step one, until surface is all capped, extruding
Pin, recipient and mould similarly sprayed glass powder；
Step 3, heated using Frequency Induction Heating mode, heating-up temperature is 850～900 DEG C, heat time heating time 8～
10min；
Step 4, enter eleven punch 11 with 36mn extruder, extrusion speed 80～120m/s, extruding force is 20～25mn.
Above-mentioned steps one pipe is preheated to 100～200 DEG C.
Above-mentioned internal diameter of the container is 165mm, a diameter of 33mm of squeezing needle.
Compared with prior art, beneficial effects of the present invention:
Present invention glass dust lubricating system, not only simple production process, and overcome pure titanium extruding at present and use
The follow-up copper sheet pickling pollution on the environment that copper-clad mode is lubricated and leads to.
The present invention does not need special installation, low cost of manufacture, can improve lumber recovery 6% about, easily realize industrialized production,
The tube surfaces quality producing is good, and plasticity is high, size uniform.
Specific embodiment
A kind of pure titanium tube extrusion process of use novel lubricating mode, comprises the steps:
Step one, surface defect process is carried out to titanium pipe blank, pipe is preheated to 100～200 DEG C；
Step 2, glass dust is sprayed into the inner surface of pipe described in step one, until surface is all capped, spraying
2～3 times；Squeezing needle, recipient and mould similarly sprayed glass powder；
Step 3, heated using Frequency Induction Heating mode, heating-up temperature is 850～900 DEG C, heat time heating time 8～
10min；
Step 4, enter eleven punch 11, internal diameter of the container 165mm with 36mn extruder, material is hot die steel
4cr5mosiv1.Squeezing needle diameter 33mm, material is hot die steel 3cr2w8v；Extrusion speed 80～120m/s, extruding force is
20～25mn；Macro-size: φ 45*6, wall thickness dimension 5.8-6.3mm, external diameter 44.8-45.4mm.
The titanium tube of the present embodiment processing, through appearance quality detection, size detection, room temperature tensile, enlarging, is flattened, Yi Jichao
The performance detections such as sonic flaw detection, tensile strength, yield strength and elongation percentage all reach the requirement of astmb 338 standard, Ke Yiman
The demand of the industrial circle pipe such as sufficient pressure vessel, condenser and heat exchanger.
The above, be only presently preferred embodiments of the present invention, and not the present invention is done with any restriction, every according to invention skill
Any simple modification, change and equivalent structure change that art is substantially made to above example, all still fall within the technology of the present invention
In the protection domain of scheme.
