Capacitor Discharge Energy Storage Spot Projection Welding Machine
The principle of the capacitive energy storage type spot welding machine is to charge and store a group of high-capacity capacitors through a small transformer in advance, and then discharge and weld the welding parts through a high-power welding resistance transformer. The outstanding features of the energy storage spot projection welding machine are short discharge time and large instantaneous current, so the thermal influence after welding, such as deformation and discoloration, is extremely small. The low-power energy storage welding machine is suitable for welding precision parts, and the high-power energy storage welding machine is suitable for multi-point projection welding, ring projection welding, and sealing projection welding.
The main features are as follows:
1. Low requirements on the power grid and will not affect the power grid
Since the principle of the energy storage welding machine is to first charge the capacitor through a small-power transformer and then discharge the workpiece through a high-power welding resistance transformer, it is not easily affected by the fluctuation of the power grid, and because the charging power is small, the power grid Compared with AC spot welders and secondary rectifier spot welders with the same welding capacity, the impact is much smaller.
2. The discharge time is short and the thermal influence is small
Since the discharge time is less than 20ms, the resistance heat generated by the parts is still conducted and diffused, and the welding process has been completed and cooling begins, so the deformation and discoloration of the welded parts can be minimized.
3. Stable welding energy
Since each time the charging voltage reaches the set value, it will stop charging and switch to discharge welding, so the fluctuation of welding energy is extremely small, which ensures the stability of welding quality.
4. Extra large current, suitable for multi-point annular convex welding, pressure-resistant sealed convex welding process.
5. No need for water cooling, saving energy consumption.
Due to the extremely short discharge time, there will be no overheating when used for a long time, and the discharge transformer and some secondary circuits of the energy storage welding machine hardly need water cooling.
