Abstract
The utility model provides a liquid-droplet welding-brazing device and belongs to the technical field of welding and brazing. By means of the device, the problem that the heat source temperature and the heat input amount are difficult to match with matrixes of brazing is solved. The welding-brazing device is based on a liquid droplet control theory, metal in a graphite crucible is heated through a high-frequency induction coil, and the constant temperature in the graphite crucible is achieved through tempered glass and thermal-insulation cotton. Supersonic vibration drives the piston to move to act on an air cylinder to generate the liquid droplet transition drive force. The liquid droplet dropping drive force is controlled through the adjustment of the air cylinder pressure, and accordingly, the liquid droplet size during dropping is controlled. Filling materials are replaced by liquid droplets, so that the strict requirements of the welding-brazing process for the heat source temperature and the heat input flow are reduced, and the filling material wetting spreading capacity is enhanced. According to the device, the applicability and the application prospect of welding and brazing are improved to a large extent, and the device is mainly used for welding-brazing construction.
