Abstract
The present invention relates to an isothermal closing technology for an aluminium alloy seamless gas cylinder, which is characterized in that the technological process comprises the following steps: a mould similar to the bottleneck is heated to 400 to 480 DEG C; a seamless aluminium alloy cold cylinder is pressed in the mould once; the pressure is from 5 to 50 tons. The present invention is the isothermal reducing technology for an aluminium alloy seamless gas cylinder, which has the advantages of once closing, high rate of finished products, simple operation and less equipment investment.
Description
The present invention relates to the manufacturing process of aluminium alloy gas cylinder, the isothermal reducing method of aluminium alloy seamless gas cylinder is provided especially.
Along with the particularly development of electronics industry of industry, to various calibrating gas, the demand of normal mixture body and hyperpure gas is more and more, bring its wilderness demand of container-aluminium alloy seamless gas cylinder of splendid attire thereupon, bottling technique is a key link in the production process of aluminium alloy gas cylinder, be that necking down sleekly was to the size that needs, so that needed valve or plug are installed after Aluminum Bottle became tube.Britain Lunfer Aluminum Bottle company is maximum in the world Aluminum Bottle production company, and their bottling technique is with after the heating of cartridge openings end, once be pressed into the similar mould of bottleneck in, can reach m=l/d＞0.32, this technology is B. P., 2000 dollars of quotations in 87 years.This technology deficiency is: 1) be that the high advantage of aluminium heat-conducting property is become shortcoming, pass to cylindrical shell very soon after the heating of end, reduced the intensity of cylindrical shell, easily heap during closing in and cause waste product.2) closing in back internal surface fold strengthens, even overlaps 3) the very difficult control of temperature, operating difficulties, thereby very high to the equipment requirement, increased manufacture cost virtually.
The object of the present invention is to provide a kind of can disposablely the closing in, and finished product rate height, simple to operate, the isothermal reducing technology of the aluminium alloy seamless gas cylinder that equipment investment is few.
The invention provides a kind of isothermal reducing technology of aluminium alloy seamless gas cylinder, it is characterized in that manufacturing process is as follows:
-will be similar to bottleneck mold heated to 400～480 ℃ between;
-the cold tube of seamless aluminum alloy once is pressed in the mould 5～50 tons of pressure.
Mentality of designing of the present invention is opposite with B. P. just, promptly mold heated is arrived the closing in temperature, cold tube once is pressed in the mould similar to bottleneck, can make m=d/D＞0.32 equally, have following advantage: 1) brought into play the high characteristics of aluminium heat-conducting property, promptly cold tube contacts in a flash with mould, just the end can be heated to the closing in temperature of aluminum alloy, closing in finishes the rear cylinder body middle and upper part and still keeps cold state, can guarantee the intensity of Aluminum Bottle, 2) the back internal surface that closes up only has slight fold, zero lap, bottleneck does not have heap, yield rate is up to more than 99%, 3) die temperature is easy to control, and is simple to operate, only need mold heated equipment and common press, invest less.At present, the present invention is the optimal selection that the aluminium alloy high pressure gas cylinder closes up.Die material used in the present invention can be selected the mold heat steel for use, as 3Cr2W8V, and 5CrNiMo.5CrMnMo etc.Selected Aluminum Bottle material can be 1) Al-Si-Mg alloy, i.e. wrought aluminium: LD2, LD5, LD6, LD8, LD9 etc., perhaps Britain and U.S.'s trade mark: 6351,6082 and 6061 etc.2) the Al-Mg alloy is rustproof aluminum alloy LF3, LF4, LF5, LF11 etc.
Below by embodiment in detail the present invention is described in detail.
The bottling technique of 18 liters of Aluminum Bottles of embodiment
The Aluminum Bottle material is LD2, diameter D=φ 140mm, wall thickness S=7mm
Mold heated to 400～480 ℃;
Mould is after temperature, and the cartridge openings end is put into mould, and 50 t hydraulic press are descending, obtains Aluminum Bottle bottleneck diameter d=φ 47mm
The bottling technique of 32 liters of Aluminum Bottles of embodiment
The Aluminum Bottle material is 6061, diameter D=φ 108mm, and wall thickness S=5.5mm,
Mold heated to 400～480 ℃,
Mould is after temperature, and the cartridge openings end is put into mould, and 50 t hydraulic press are descending, obtain Aluminum Bottle, bottleneck diameter d=φ 36mm.
