Technical Field

The invention relates to the technical field of lamp manufacturing, in particular to a filament lamp core column loudspeaker cooling device.

Background

The filament lamp core column is made of glass, and one end of the core column is in an outwards turned horn shape so as to be convenient for assembling a seal and ensure air tightness. The stem loudspeaker is made by stem loudspeaker forming equipment, and the existing stem loudspeaker is easy to break due to the thinner bell mouth. If the crack is early, the horn is scrapped; when the bubble shell is sealed, the seal is broken, the seal is scrapped, the bubble sealing forming of the bubble shell is directly influenced, and the integral reject ratio is 3-5%; even after the product is finished, there is a risk of breakage, which means that the overall quality and service life of the product is affected. Therefore, the quality of the stem flare is critical. In the prior art, the bell mouth is naturally cooled, the cooling time is long, and the hardness and the strength of the bell mouth are improved less. The cooling effect by using the machine is generally poor, and the rejection rate of the horn is high.

For example, the annealing device for the stem trumpet machine disclosed in the chinese patent document, whose publication number CN104045225A, includes a working table and an air supply system of the stem trumpet machine, and a station clamp corresponding to the next station for flaring, a blowpipe is provided below the station clamp, and the blowpipe is communicated with the air supply system. The blowing device is communicated with a low-pressure air supply system of the core column horn machine, a station clamp is turned above the blowing pipe after the glass pipe horn is formed, and an air outlet of the blowing pipe performs blowing annealing from bottom to top on the horn part of the workpiece in a hot state. The invention has the disadvantages that the air is blown from bottom to top, only the inner side of the horn is cooled, so that the density of the crystal structure at the inner side of the horn is inconsistent with that at the outer side, the hardness strength difference between the inner side and the outer side is large, and the horn is still easy to break; in addition, the air supply system is a low-pressure air supply system, so that the cooling time is long and the efficiency is low.

Disclosure of Invention

The invention provides a cooling device for a stem loudspeaker of a filament lamp, aiming at overcoming the problems of low overall hardness and strength, easy cracking and high rejection rate of the stem loudspeaker in the prior art.
