Abstract
The present invention relates to the manufacture method of the common bulb stem stem below 100 watts, be characterized in adopting white material or plumbous material to make glass-tube or glass stalk after, the stem stem of making inflation bubble or vacuum bubbles or inflation bubble and vacuum bubbles is flattened in hybrid combining.The stem stem of producing with this method surpasses ministry standard useful life, and percent defective is lower than the percent defective of plumbous material stem stem, and production cost reduces greatly, is a kind of manufacture method of comparatively desirable common bulb stem stem, is applicable to that bulb manufactory applies.
Description
The present invention relates to the manufacture method of the common bulb stem stem below 100 watts.
The common bulb stem stem is made up of loudspeaker bar (1), blast pipe (2), real core stalk (3), glass knot (4), molybdenum wire hook (5), lead (7).Usually loudspeaker bar (1), blast pipe (2), real core stalk (3) all adopt plumbous material (red lead material) material to make.Because plumbous material price height, the low plumbous material of Chinese market is general 3000 yuan/ton at present.In order to reduce cost, people seek cheap material, adopt white material (white clouds building stones), its price is 1400-1500 unit/ton, make loudspeaker bars (1) and blast pipe (2) and real core stalk (3) with it, its result 1, the fried loudspeaker bar (1) of normal appearance, disconnected blast pipe (2) and real core stalk (3) phenomenon cause the stem stem percent defective up to more than 3%.2, bulb life is short.Because with the inflation bubble that it is produced, because of the temperature height, potential difference is big at glass knot place, and electrolysis easily takes place, and causes " thermal breakdown ", produces to jump electricity, thereby burns out filament (6).When producing inflation bubble and vacuum bubbles with it, vacation takes place and grills thoroughly phenomenon in difficult control easily when making stem stem accent fire, causes bulb gas leakage.
The objective of the invention is to overcome above-mentioned weak point, the novel manufacturing method of producing the inexpensive general bubble stem stem below 100 watts is provided.
It is as follows to be described in detail technical scheme of the present invention in conjunction with the accompanying drawings:
Accompanying drawing: common bulb structural representation.
Characteristics of the present invention are after adopting white material (white clouds building stones) or plumbous material (red lead material) to make glass-tube and glass stalk to be loudspeaker bar (1) and blast pipe (2) and real core stalk (3), and hybrid combining is flattened and made that inflation bubble or vacuum bubbles or inflation steep and the stem stem of vacuum bubbles.Its combining form and process conditions are as follows: 1, the stem stem of inflation bubble and vacuum bubbles is to flatten and make with white material loudspeaker bars (1), plumbous material blast pipe (2), the plumbous real core stalk of material (3) combination.2, the stem stem of inflation bubble is with expecting loudspeaker bars (1) in vain, expecting that blast pipe (2), the plumbous real core stalk of material (3) make up flattening and make in vain.3, the stem stem of vacuum bubbles is with white material loudspeaker bars (1), expects that real core obstructs (3), plumbous material blast pipe (2) combination is flattened and made in vain.White material loudspeaker bars (1) adopt light-wall pipe, and its caliber is controlled to be φ 12.2-13.0mm, and tube wall is 0.86-1.0mm.Faster because of white material than the cooling of lead material, if wall thickness is too thick, be easy to generate internal stress, cause fried loudspeaker and " opening five " phenomenon to take place.The angle of loudspeaker is 65 ° ± 5 °, and the diameter at butt end of loudspeaker is controlled to be φ 20-22mm.The loudspeaker angle [alpha] becomes 65 ° ± 5 ° by original 90 °, the enlarging face that can make loudspeaker is near with the distance of glass bulb neck, loudspeaker with the glass bulb neck when bonding, the loudspeaker internal-external temperature difference reduces, internal stress also reduces simultaneously, thereby the phenomenon of fried loudspeaker greatly reduces.White material blast pipe (2) caliber is controlled to be φ 3.5-3.8mm, and wall thickness is 0.58-0.66mm.The white real core stalk of material (3) is by the requirement of former lead material manufacturing technology.
Make the process conditions of stem stem:
1, it is ripe that manufacturing stem stem flame is controlled at burning, and don't burn out under the prerequisite of Dumet wire, adopts oxidizing flame when transferring fire partially firmly.
2, firer position, second road ability oxygen before flattening, its effect grills thoroughly glass on the one hand, makes on the other hand on former roads station and is reduced out filemot material, is oxidized to former material once more.Former plumbous material technology is that employing four road stations before flattening all adopt the flame enrichment oxygenation, so oxygen demand is 3 times of the present invention.
3, after the flattening, prolong the fire position on the machine, reduce stem stem to the preceding temperature difference of annealing furnace, the product internal stress reduces, and percent defective greatly reduces.
4, the flame location of stem stem annealing places on the chain with loudspeaker, and the fire door place that goes forward side by side is a standard, and both sides flame is transferred to the place that is higher than loudspeaker lower surface 3mm, and the angle between two flames is 70 °-80 °, and annealing temperature is controlled at 540-620 ℃ in stove.
5, the diameter of glass knot (5) is φ 6.5mm, strengthens the distance of molybdenum wire hook and can avoid and reduce " thermal breakdown " phenomenon, generally controls between molybdenum wire hook angle and is 45 ° and is advisable.
6, in order to make loudspeaker and cell-shell (7) reach sealing by fusing state preferably, be example with 24 automatic sealing cars below, make zero-bit direction left with the typing clamping, what time transfer fiery main points below noting during operation:
A, the 4th, 5 two station add gentle breeze from blast pipe, help automatic shelling, and the 3rd station continues to add wind, avoid loudspeaker limit and glass bulb to form too much dead glass, and the 2nd station continues to add wind, and it is principle that the air quantity size does not cave in inward with sealing-in place.
B, seal flame and be soft, fluffy big shape, cell-shell seals each later station with loudspeaker and adds ramuscule blowing simultaneously, and the aligning cell-shell first half, reduces temperature inside and outside the cell-shell with cold wind.Simultaneously: reduce the granularity of red phosphorus, increase the adhesive capacity of red phosphorus and filament.
Of the present invention compared with prior art have a following effect:
Use plumbous material to make the situation of scrapping of stem stem on the table 1:1988 1-3 month 18
| Production time | Packing sum (only) | Stem stem is scrapped situation | ||
| Fried loudspeaker | Open five | Disconnected bar | ||
| 88 years 1-3 months 18 | 374090 | 3595 | 520 | 1395 |
| Percent defective (%) | 0.96 | 0.14 | 0.37 | |
Table 2: the stem stem that uses method of the present invention to produce is scrapped situation
| Production time | Packing sum (only) | Stem stem is scrapped situation | ||
| Fried loudspeaker | Open five | Disconnected bar | ||
| The 23-9 month 15 in August, 89 | 130975 | 859 | 144 | 476 |
| Percent defective (%) | 0.66 | 0.11 | 0.36 | |
1, the stem stem scrappage is lower than plumbous material stem stem percent defective.
2, conserve oxygen: to produce 1500 ten thousand per year, can save 2500 bottles every year, be worth 20000 yuan.
3, reach 1123 hours useful life (ministry standard is 1000 hours).
4, reduced cost:
0.012 yuan/root of plumbous material oviduct, 0.0057 yuan/root of white material oviduct, annual production needs with oviduct by 10 tons, can save 120,000 yuan in 1 year, 0.007 yuan/root of the real core stalk of plumbous material is expected 0.0037 yuan/root of real core stalk in vain, and the real core stalk of the white material of per kilogram is all expected low 1.8 yuan of real core stalk than lead, annual by 9,000,000 vacuum bubbles, can save 30,000 yuan every year.
The present invention is a kind of manufacture method of comparatively desirable common bulb stem stem, is widely used in bulb producer and applies.
