ABSTRACT:
A method of assembling electric lamp prongs and an installation for realization thereof relate to the equipment for making electric vacuum devices, e.g., incandescent and fluorescent lamps.
According to this method the prong parts, i.e., flanges and exhaust tubes held in the clamps of a chain conveyor are heated before fitting them with electrodes. In the installation for the realization of said method the burners for heating the flanges and the exhaust tubes are installed in the order of prong assembly before the electrode-loading device, the actuating mechanisms of the electrode-loading device, the prong-stamping mechanism and the exhaust tube hole-blowing mechanism being located on one of the conveyor sprockets. This rules out the burning up of electrodes during heating of the prong parts, reduces considerably the time required for heating the parts, steps up the output and simplifies the design of the installation.
