Definitions
- the invention relates to methods for producing helically wound spiral bodies according to the preamble of claim 1 or claim 2.
- Es are either incandescent in the sense of simple or also double coiled filament for incandescent lamps according to the generic term of claim 1 or for coils for pin electrodes of high-pressure discharge lamps according to the preamble of claim 2.
- EP-A 149 282 already discloses a process for producing helically wound Incandescent known.
- the filament (coil) is then wound onto the core wire heated to approx. 1900 to 2200 ° C to reduce tensions, for example by means of laser, high frequency or resistance heating of the core wire.
- the glow wire is held on the core wire.
- This cumbersome Procedure is necessary because of the inside diameter of the coil is adapted to the outside diameter of the cored wire and therefore not too avoid that the coil sticks to the core wire.
- a similar process involving heat treatment of the filament for removal the voltages and then triggering the core wire the spiral is also known from DE-OS 34 35 323 and JP-OS 49-67 481.
- the latter used as a means of heating the coil to a temperature a lamp between 600 and 900 ° C.
- a method according to the invention for producing helically wound incandescent bodies uses the technique which is known per se, in which a glow wire made of high-melting material, usually tungsten, is wound onto a core wire and is thermally treated, and is then separated and the core wire is detached.
- a glow wire made of high-melting material usually tungsten
- the new process is based on the idea of winding wire material to influence thermally already during the winding process. Across from conventional methods, in which you also put the filament on one Endloskem winds, you save the subsequent operation of the Relaxation annealing on the core wire in the pulling process. In particular it must be ensured that the radius of curvature of the Coil on which the glow wire subsequently acts after exposure to temperature is wound, is small compared to the axial length of those to be produced from it Mantles. In a particularly preferred embodiment the spiral is separated immediately after winding, so that on a winding can be dispensed with.
- the winding material is additional through the winding process elastic deformation up to the yield point of the wrapping material forced the so-called torsional stress.
- the first method step according to the invention is that the filament is thermally treated.
- the filament In the case of the manufacture of incandescent bodies, the filament must be on a Temperature brought close to the recrystallization temperature of the material become. A temperature in the range between is preferably suitable for this 60 and 90% of the recrystallization temperature. In the case of tungsten this means that the filament reaches a temperature of more than 1200 ° C, preferably more than 1400 ° C is brought. The recrystallization temperature the tungsten is around 1800 C.
- the heated filament is used in both embodiments or coil body wound on the core.
- a noticeable cooling to prevent the spiral produced in this way from heating up of the spiral takes place close to the core.
- Core here includes both core wires and solid core pins.
- the spiral is still hot, but has already cooled slightly sporadically. If the spiral is still too hot before separating, it runs it is colored or oxidation can occur. In the worst case the spiral opens too little or not at all. It also hangs the so-called life of the core.
- the finished spiral has the Separate a residual voltage that occurs immediately after the separation translates into an increase in the inside diameter of the helix, so that the coil loses intimate contact with the core wire. It is sitting only loosely on the core wire.
- the thermal treatment is preferably carried out for both embodiments the winding wire by means of a plasma torch.
- a plasma torch The principle of such Plasma torches are described in more detail, for example, in NL-A 71 12 767.
- Plasma can be, for example, argon, helium, hydrogen, nitrogen and use their mixtures.
- the plasma is burnt in the free gas stream, in particular argon, an argon / nitrogen mixture or an argon / hydrogen mixture is used becomes.
- nitrogen can also be used as a protective gas cone become.
- Both the anode and the cathode are advantageously located of the plasma torch in the burner housing.
- the filament should advantageously have a temperature of more before winding reach than 1200 ° C.
- An interchangeable core is particularly well suited for the production of the glow wire (Machine core) as the core, since this stabilizes the winding process and Tolerances in the winding process minimized. It is recommended that the machine core made of thermally resilient (in the temperature range around 1800 ° C) Material such as Spring steel or tungsten. The machine core should tolerate temperatures up to more than 1800 ° C.
- the material of the winding wire is typical Tungsten, possibly with additives such as potassium, silicon, aluminum and / or thorium can be doped.
- the new method of the first embodiment is used in manufacturing achieved by incandescent bodies that by the winding process in the Helix introduced tension due to the previously made thermal treatment is influenced so that the spiral after able to separate due to the stored mechanical energy is to jump open radially.
- the radial jump is exactly that above described elastic residual stress component. Because of this, this resolves Spiral automatically from the core wire, in contrast to the prior art, where this step is the biggest problem.
- the surprising property that the spiral is particularly advantageous remains almost dimensionally stable in the axial direction.
- the axial opening is analog to turn a spring also elastic and is reflected in the reduction of the wound turns in compliance with the given Winding length.
- the small axial is expressed Residual voltage in that they have only a slight spread of Total length of the helically wound filament causes.
- the temperature during the thermal pretreatment is the first Embodiment just chosen so that the desired final The inner diameter of the helix automatically due to the radial opening after separating.
- the exact one depends on the specific individual case Dimensioning essentially of the diameter of the core and winding material, on the temperature and also on the winding speed.
- the increase in the inside diameter of the spiral caused by radial opening is type-specific and moves in one area from 2 to 30%.
- the desired dimensions can be of the spiral with a compared to the prior art achieve smaller core wire.
- the procedure In the case of the double-coiled filament, the procedure must be modified by using a conventionally made endless primary helix, that is still wound on a core wire, as core wire is used for a secondary helix. The procedure described above is then used to make the secondary helix. After that Then the further processing steps or the triggering directly of the primary nucleus.
- the method is suitable for all known diameters of the core wire or glow wire and is applicable to all known gradients.
- Diameter of the glow wire and core wire is due increasing surface adhesion a tendency to glue the glow wire observed with the core wire.
- This so-called revolver technique enables a longer period of use (Service life) of a machine core.
- Revolver technology means one automatic feeding of a material before the n + 1-th process step, however after completion of the previous nth process step. With a revolver, this corresponds to the automatic feeding of the next one Cartridge chamber and contents after firing a shot.
- a second area of application is pin electrodes for discharge lamps with spirals attached.
- Such electrodes are made of, for example US-A 3 067 357 known.
- such electrodes can be produced by particularly high in the thermal heat treatment of the winding wire Temperatures in the range of the recrystallization temperature used Materials are used. In the case of tungsten temperatures preferably around or just above 1800 ° C. This will the elastic residual tensions which cause the helix to spring open, prevented. In this way, the winding wire on the core pin or "Burn" the electrode shaft.
- the impressed tensions are nothing more than one forced minimal change in the crystal lattice of a grain or Crystallites that also differ in bond lengths, angles and bond forces reflect. Smeared with every temperature increase of a material the position of the atoms in the crystal lattice more, i.e. their location will be for a special structure is becoming ever more unfavorable in energy terms and even a reversible one Phase transformation (e.g. conversion of the ⁇ phase of a crystal into the ⁇ phase), being above a certain temperature for the prevailing Taken a different, energetically more favorable structure becomes. The sum of the microscopic lattice distortions gives the macroscopic Residual stresses.
- the press fit is the reverse of the winding technique of incandescent bodies. This is because an elastic electrode coil becomes retrofitted provided with a core pin, the outer diameter of which is larger than the inside diameter of the electrode coil. The electrode coil is expanded. The elastic deformation generated by the Feeding the pen a resilient force. Thus the pen is by means of Friction of the individual turns recorded.
- the coil is normally slid on and then welded to the core pin or the core pin is added later inserted into the helix (press fit).
- the process does not require welding or pressing, since the Helps hold the core well on its own.
- one is Damage to the electrode (embrittlement), as occurs during the welding process unavoidable would no longer be possible.
- a displaceable machine core 1 made of spring steel is on one End in a holder 2a and at the other end in a counter holder 2b guided by means of a radial forming and clamping device 15. It can be withdrawn or pushed out in the holder 2a become.
- a stationary machine core can also be used and a moving wire feed unit can be used.
- a glow wire 3 is coming as a winding material from a supply coil 6, whose axis 8 is arranged parallel to the machine core 1, by means of a wire feed (not shown) on the machine core 1 to one Coil 13 wound in compliance with a predetermined slope, the is set by means of a pitch drive 9.
- a section of the glow wire 3 hits the machine core 1, it is thermally treated by means of a plasma torch 4.
- the plasma heating takes place in the free gas stream by means of an argon plasma 5
- Plasma torch is only in operation, while a winding drive 12 and Incline drive 9 are active. If the intended length of a filament is wound, a wire cutter 7 comes into action and lengthens the Illuminant off. The coil jumps up and can be easily stripped off, while the machine core 1 is retracted. Immidiatly after the wire feeder starts again and the plasma torch enters again Action.
- a suitable machine control with appropriate drives ensures the combination of winding process and at the same time thermal treatment of the winding material depending on the speed.
- a simply coiled filament 10 for festoon lamps 20 (Halogen incandescent lamps) with four luminous segments (each about 70 narrow Turns) and three interruptions (five each wide turns) and two ends (eight wide turns each).
- the machine core consists of spring steel with a diameter of 1.4 mm.
- the total clamping length is more than 50 mm.
- the diameter of the filament is about 120 microns.
- Fig. 3 shows schematically a double-coiled filament 11, the Secondary helix is produced by the method according to the invention.
- the filament consists of tungsten.
- an electrode 14 which consists of a core pin or electrode shaft 18 and a coil 19 wound thereon.
- the spiral 19 is burned onto the core pin 18.
