The utility model provides a self-priming nozzle which can be used on a metal plate quenching machine. The self-priming nozzle is installed between the upper pressing rollers of the quenching machine as an upper nozzle.
and is mounted between the lower conveying rollers of the quenching machine as a lower nozzle. Both the upper nozzle and the lower nozzle are provided with an injection port and a water-blocking roller, and the injection port is at an angle with the running direction of the metal plate.
and the water-blocking roller is pressed against the upper and lower surfaces of the workpiece to be quenched by an actuator, respectively. The upper nozzle and the lower nozzle are provided with a collecting water tank between the injection port and the water blocking roller, and excess cooling water is rushed toward the collecting water tank and discharged from both sides of the collecting water tank.
The self-priming nozzle can effectively reduce the cooling residual water on the surface of the steel plate, and also makes the contact area corresponding to the upper and lower surfaces of the quenched metal plate and the upper and lower nozzles uniformly cooled, which can increase the cooling uniformity of the quenched metal plate.
