Specific embodiment
A kind of method of present invention coiling filament, it comprises the steps of：
(1), get out the molybdenum filament after checking and tungsten filament, carry out a wrapping wire, using molybdenum filament as heart yearn, by tungsten filament by throw around by way of be wound on molybdenum filament, form winding body of filament, throw and be 30,000 revs/min around motor speed；
(2) after, checking a winding body qualified, carry out secondary wrapping wire, using molybdenum filament as heart yearn, winding body of filament is turned to the secondary winding body of helical heater by spiral filament forming machine, the motor speed of spiral filament forming machine is 1410 revs/min；
(3) after, checking secondary winding body qualified, annealing in hydrogen atmosphere heat treatment is carried out to secondary winding body, secondary winding body passes sequentially through wet hydrogen hydrogen-burning stove and dry hydrogen hydrogen-burning stove, wet hydrogen hydrogen-burning stove is 1050 DEG C -1150 DEG C, the temperature of dry hydrogen hydrogen-burning stove is 1500 DEG C -1600 DEG C, and secondary winding body wire travelling speed is 2.2 ms/min -3.2 ms/min；
(4), the secondary winding body after coiling is carried out shredding operation；
(5), to secondary winding body the carrying out silk operation after shredding, dissolve molybdenum heart yearn, obtain helical tungsten filamen；
(6), filament cleaning and centrifuge dewatering；
(7), the baking oven that tungsten filament is put into 150 DEG C -200 DEG C carries out drying operation, and drying time is 30 minutes；
(8), the tungsten filament after drying is detected；
(9), the tungsten filament qualified to detection carries out packaging and storage.
Wherein, the hydrogen being passed through in described wet hydrogen hydrogen-burning stove is the hydrogen containing vapor, and the hydrogen being passed through in dry hydrogen hydrogen-burning stove is the hydrogen crossed through desiccant dryness.
When tungsten filament specification is 0.6mg/mm-1.3mg/mm, during a diameter of 0.12mm-0.15mm of molybdenum filament, in wet hydrogen hydrogen-burning stove, temperature is 1100 DEG C, and dry hydrogen annealing in hydrogen atmosphere furnace temperature is 1550 DEG C.
The present invention obtains secondary winding body by wrapping wire, a secondary wrapping wire, wet hydrogen hydrogen-burning stove plays styling to the tungsten filament in secondary winding body, dry hydrogen hydrogen-burning stove serves further consolidation effect to the sizing of tungsten filament, and the effect of recrystallizing is played to tungsten filament, to avoid producing impact because tungsten filament internal crystal structure in wet hydrogen stove changes to filament quality, by this secondary wrapping wire and secondary sizing, the filament shaping effect that coiling obtains is good, processing technology is simply effective, reduce cost, improve efficiency.
