Abstract
The utility model relates to a core column processing device, in particular to a flat-clamping splint for pressing a core column. The flat-clamping splint is characterized in that: bulges which are mutually inosculated in a staggered manner are arranged at the inner side of the flat-clamping splint; furthermore, the bulges are straight stripes which are transversely arrayed. The two flat-clamping splints with transversely-arrayed concave-convex stripes which are mutually inosculated in a staggered manner can exert a strong positive pressure on the core column and lead the core column to be compacted with a guide wire; by employing the above core column pressing method, the rate of finished products can be improved by 30%.
Description
Technical field
The utility model relates to a kind of processing unit (plant) of stem stem, especially a kind of flat clamping plate of folder of suppressing stem stem.
Background technology
Deuterium lamp belongs to a kind of light source of arc discharge type in the gaseous discharge lamp.Can give off 160nm ~ 400nm continuous distribution ultraviolet spectra from optical window during its work.So it is that present ultraviolet specrophotometer is as desirable ultraviolet source.But different company useful life of deuterium lamp differ bigger, do not wait from 500 ~ 4000 hours, this mainly is relevant with the packaging technology of the stem stem of deuterium lamp, stem stem be the pillar (shell of tube core, negative electrode, anode) is outer contact with lamp again, function with lead-out wire, its compacting sealing-in quality has a direct impact for rate of finished products that improves deuterium lamp and maintenance vacuum degree reliably and with long-term, entering air in the deuterium lamp causes deuterium lamp to lose efficacy easily, traditional stem stem processing method is because clamping plate are provided with circular hole, can stay salient point in the above on the compacting stem stem, be unfavorable for that the folder of stem stem is real.
Summary of the invention
For the press process technology that overcomes traditional stem stem easily causes the deficiency of chronic leakage, the purpose of this utility model provides a kind of flat clamping plate of folder of suppressing stem stem.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of flat clamping plate of folder of suppressing stem stem, its inboard has the identical burr that staggers mutually.
Further, above-mentioned burr is transversely arranged vertical bar line.
The invention has the beneficial effects as follows: such two have transversely arranged concave and convex stripe and their the concave and convex stripe flat clamping plate of identical folder that stagger mutually and can produce stronger positive pressure to stem stem, with stem stem and seal wire compacting, adopt this stem stem drawing method rate of finished products can be improved 30%.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the flat clamping plate of folder.
Fig. 2 is the process schematic representation that utilizes the flat clamping plate compacting of folder of the present utility model stem stem.
Fig. 3 is the structural representation of the stem stem after pressing from both sides in fact.
Among the figure: 1. press from both sides flat clamping plate, 2. horn mouth, 3. burr, 4. seal wire.
Embodiment
The flat clamping plate of folder of compacting stem stem are used for the deuterium lamp stem stem, as shown in Figure 2 the physical dimension flange flue of an end of deuterium lamp core glass column, so that assembling stem stem and deuterium lamp glass-tube seal the assurance air-tightness by designing requirement.The glass that stem stem is pressed from both sides flat place burns ripe grilling thoroughly, and makes glass and the combining together of seal wire 4 natures is made up of molybdenum rod, molybdenum sheet, the flat clamping plate 1 of folder are arranged on the horn mouth 2 of stem stem Founder pressure.The structure of pressing from both sides flat clamping plate 1 as shown in Figure 1, its inboard has the identical burr 3 that staggers mutually, burr 3 is transversely arranged vertical bar line.Utilize these the two flat clamping plate 1 of folder that glass and seal wire 4 folders that stem stem presss from both sides flat place are real, the structural representation of the stem stem after folder is real as shown in Figure 3.
Claims (2)
1, a kind of flat clamping plate of folder of suppressing stem stem, it is characterized in that: its inboard has the identical burr (3) that staggers mutually.
2, the flat clamping plate of the folder of compacting stem stem according to claim 1 is characterized in that: described burr (3) is transversely arranged vertical bar line.
