Embodiment
[0021] In this embodiment, a riveting gun was designed and manufactured according to the schematic diagram of the riveting gun, and a power supply was manufactured according to the schematic diagram of the power supply, and a riveting test was carried out with a top iron. The riveting system power supply includes a group of pulse capacitors with a rated voltage of 450 volts and a rated capacitance of 4700 microfarads connected in parallel to form a main coil discharge capacitor bank, and the auxiliary coil capacitor bank uses several capacitors with a rated voltage of 450 volts and a rated capacity of 2200 microfarads; The two discharge circuits use high-power semiconductor switches to control the discharge of the discharge circuit; the two charging circuits use a resonant soft switch to control the charge.
[0022] In the implementation, first charge the auxiliary coil capacitor to the set voltage, then discharge to pull the mover back to the initial position; then charge the ...
