Background
The electrodes are the core component of a high-pressure gas discharge lamp, which, under alternating voltage, have the effect of emitting electrons and receiving electrons. The electrode generally comprises a core rod and a spring sleeved outside the core rod, and the assembly modes of the core rod and the spring mainly comprise the following two modes:
1. And (3) spot welding. When the core rod and the spring are loosened, the spring is manually placed in the clamp, then the core rod penetrates into the spring, and finally the core rod and the spring are fixed together through resistance welding. In the mode, the size of the special clamp directly influences the assembly size of the electrode, so that the clamp needs to be polished regularly after being used for a period of time, and the operation complexity and the processing time are increased;
2. Punching core type. When the core rod is tightly matched with the spring, the spring is manually placed into a special grinding tool hole, and then the core rod is slowly knocked into the spring by a small hammer. The mode has higher matching requirements on the spring and the core rod, and if the interference degree is too large, the core rod cannot be successfully punched or is napped after being punched; if the interference degree is too small, the matching firmness of the core rod and the spring can be affected.
