Abstract

The invention discloses an energy-saving lamp annealing process which comprises the following steps: a quick heating segment: rising a temperature of an energy-saving lamp tube to 10-30 DEG C, being lower than an annealing temperature; a slow heating segment: rising the temperature to the annealing temperature; a first heat preservation segment: preserving heat at the annealing temperature; a slow cooling segment: cooling to the temperature being lower than the annealing temperature by 50-100 DEG C; a quick cooling segment: cooling to the temperature being lower than the annealing temperature by 200-300 DEG C; and a second heat preservation segment: preserving the heat at the temperature after the quick cooling step is finished. According to the energy-saving lamp annealing process, by innovatively configuring details of temperature rising and cooling links, temporary stress or permanent stress generated on the lamp tube can be effectively eliminated through heat preservation treatment for 6-8min, so that the explosion phenomenon of the lamp tube in the annealing process is prevented from occurring.

Description

technical field [0001] The invention relates to the field of energy-saving lamp processing, in particular to an annealing process for an energy-saving lamp. Background technique [0002] Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to lighting equipment that combines fluorescent lamps and ballasts (ballasts) into a whole. [0003] The annealing process in the production of energy-saving lamps is often overlooked because of its simplicity. However, the actual annealing process has an important impact on the production of energy-saving lamps, and if it is not handled properly, it will cause bursting problems. The reason for the bursting is that the temporary stress or permanent stress on the lamp tube exceeds the ultimate tensile strength that the lamp glass material can withstand during the processing of the lamp tube. The cracking phenomenon in the annealing process generally occ...
