Definitions
- This invention relates to spin forming of metals. More particularly it relates to the process by which pressure vessels are formed by spin forming ends and necks on tubes and to the means of carrying out the process.
- the principal object of this invention is to provide a process and apparatus which avoids the adverse effects of the heating which is incidental to the spin forming of the ends and necks on tubes intended to be used for seamless metal tanks, gas bottles, pressure vessels and the like.
- Another object of this invention is to provide a method and apparatus for producing such vessels from tubular stock, rapidly and with uniform properties.
- the present invention resides in controlling the temperature of a heat sensitive metal such as aluminum alloy 6061 during spin forming so that the physical properties of the unworked portions of the metal are unaffected by the temperature changes which occur during spin forming and so that the worked portions of the metal have desired dimensions and physical properties.
- a conventional torch is used to preheat the work and then as the work is further heated it is simultaneously cooled by a cool gas or a liquid cryogen such as carbon dioxide, nitrogen, helium, argon, or any other gas which can provide the desired cooling action without adversely affecting the surface properties of the part being spun.
- a cool gas or a liquid cryogen such as carbon dioxide, nitrogen, helium, argon, or any other gas which can provide the desired cooling action without adversely affecting the surface properties of the part being spun.
- Figure 1 shows a fragment of a tube or pipe 10 mounted in a hollow chuck 12 for rotation about its axis 14.
- Chuck 12 is provided with conventional clamping means (not shown) to grip the tube or pipe 10.
- the extent to which the tube or pipe is inserted into the chuck depends on the length of the tube or pipe, the speed at which it is to be rotated, whether it is given additional support, and other factors which may be readily ascertained by anyone practicing this process as evidenced by the patents noted above.
- the free end of the pipe 18 actually extends a considerable distance from chuck 12.
- Figure 2 shows the apparatus during the preheating step.
- a forming tool in this instance a rotating wheel 16 is shown adjacent the end 18 of pipe 10.
- Means 20 are provided for supporting wheel 16 so that it may be advanced along the axis 14 of pipe 10 and toward and away from axis 14, such means being known in the art and forming no part of the present invention.
- Preheating of the end 18 of pipe 10 is by means of one or more torches 21 directed toward the end of the pipe and disposed between the end of the pipe and chuck 12.
- the amount of preheating is monitored by an optical pyrometer 22 directed toward the portion of the pipe which is being preheated.
- Pyrometer 22 detects the temperature of the pipe and signals the result to a temperature gauge 24, which is connected to a control means 30, whereby the fuel fed to one or more torches 21 from a supply 36 by a valve 34 is controlled by controller 30 so as to produce a desired temperature in the work, for example an aluminum alloy tube 10 might be preheated to a temperature of about 350°F and from 350°F to a temperature of 650° - 750°F within an interval of 1 to 2 minutes after being placed in the chuck.
- a means for applying coolant to the pipe or tube 10 including a coolant discharge tube 38 connected to a coolant supply 46 which is controlled by a valve 42 which is actuated by a controller 32.
- An optical pyrometer 22' actuates controller 32.
- Temperature gauge 26 is provided to permit the operator to visually check on the temperatures of the workpiece adjacent to chuck 12.
- a further quenching means is shown in Figure 2, namely pipe 40 connected to coolant supply 46 through a valve 44. Valve 44 is controlled by optical pyrometer 22 and controller 30. At the stage of the process shown in Figure 2 coolant is being discharged by pipe 38 but not by pipe 40.
- Figure 3 shows the first phase of dome formation in which the end of the pipe, now at a temperature of 650° - 750°C is nosed in while rotating, by moving the spinning wheel 16 into contact with the preheated end 18 of pipe 10. This step takes about 15 seconds.
- Figure 4 shows the next phase of dome formation in which the end of tube 10 is almost closed. This step takes about 30 seconds, and is effected while the pipe temperature is maintained between 650°F and 750°F.
- Figures 5 and 6 schematically show the formation of the neck on the pipe, by suitable movement of the spin forming wheel 16 while maintaining coolant through pipe 38 and heating through torch 21, so that the tube at the chuck mouth is maintained at a temperature below about 350°F and the portion of the tube being formed into a neck is maintained at about 650°F - 750°F; the operation in Figure 5 taking about 30 seconds while that in Figure 6 talking about 15 seconds.
- FIG. 7 illustrates the rapid quenching step which follows completion of the neck formation. Torch 21 has been extinguished and coolant is now applied by both pipe 40 and pipe 38. Spin forming wheel 16 has been withdrawn from the work. Rapid quenching reduces the temperature of the work to about 350°F in from about 60-90 seconds.
- tube 10 is an aluminum tube originally supplied as an extrusion with a temper of T-6 and consisting of alloy 6061 which has a nominal analysis of 0.8/1.2 Mg, 0.4/0.8 Si, 0.15/0.35 Cr, 0.15/0.40 Cu, and the balance aluminum. Obviously for other grades of aluminum alloy and for other nonferrous or ferrous alloys such as stainless steels other parameters of temperature will apply.
- Figure 2 illustrates a preferred cooling system for insuring that the work does not lose its temper, or deteriorate physically as a result of the heating by torch and the heating due to the working incidental to the shaping of the dome on the tube.
- a coolant introduced through the chuck into the interior of the pipe 10. This would appear to be especially desirable in spin forming thicker tubes and to supplement the quenching step so that quenching can be accomplished in a minimum of time.
- the physical properties existing in the tube prior to spin forming are not adversely affected by the temperature changes which the tube experiences during spin forming and consequently the end product can be used in the construction of light weight gas cylinders for storing cryogenic gases at high pressures and low temperatures where such properties are essential.
- the cooling depends on the temperatures reached at various stages of the spin forming, and may be either continuous or intermittent. Because of the use of cryogenic coolants such as liquid C0 2 the cooling is sufficiently rapid to produce a uniform crystalline profile across the dome wall, which is not possible with relatively thick walled workpieces employing air cooling or water cooling.
- gas fired torch 21 heats a region 12-15" in width adjacent the end of tube 10 and pipe 38 applies coolant to the portion of th6 pipe extending up to about 18 inches from the chuck 12.
