The shot blasting machine accelerates the steel shot to the specified speed by rotating the impeller, hits the surface of the part to be strengthened, and achieves the specified strengthening value. The compressed air is used to pull out the steel shot in the hopper through the suction nozzle, and the steel shot is input to the steel shot classifier through the pneumatic conveying device. The air and dust are discharged by the ventilation device, and the steel shot enters the high-speed rotating rotor to be accelerated, and the steel shot reaching the predetermined striking speed is shot from the nozzle to the workpiece to complete the strengthening of the surface of the part. How to strengthen the surface of the catenary shot blasting machine?
The workpiece is mounted on the fixture and slowly rotated so that all surfaces of the workpiece are strengthened. After the steel shot hits the parts, it returns to the hopper through the silo wall, and the strengthening work of a batch of workpieces is completed after reaching the strengthening time specified in the process. Catenary shot blasting machine is composed of shell, rotor, steel shot conveying, steel shot sorting, power and control. The shell is mounted on the base, and a rotor is installed in the shell. The upper part of the shell is provided with a steel shot separator, a transmission part and a steel shot conveying device. The control cabinet is fixed to the bench pedal. The separator is composed of an outer cylinder, an inner cylinder and a spiral channel. The mixed flow of compressed air and steel shot enters the steel shot separator along the conveying channel of the pneumatic conveying device, and the qualified steel shot flows to the outer cylinder and falls to its bottom due to the action of centrifugal force.
Air enters the ventilation system along the inner cylinder, and the unqualified steel pellets are separated. The bottom of the separator is provided with a filter screen and a cone body, through which qualified steel pellets are transported to the exit of the separator. The outer cylinder wall of the separator is provided with an observation window for observing the condition of the steel pellets in the separator and removing the waste pellets. The rotor is rotated by a motor. The shell of the rotor is equipped with a blade, and the steel shot enters the blade from the center of the rotor and is accelerated by the rotating blade. Under the combined action of centrifugal force and circular motion, the steel shot is thrown out from the ejection port outside the blade. The hollow shaft is used to drive the rotation of the machined part. The hollow shaft transmits the rotating power by the gear, and eight hollow shafts rotate at the same speed at the same time through the gear meshing. The lower part of the hollow shaft is provided with a mechanical seal and a packing seal device to prevent steel pellets from entering the bearing. Such catenary shot blasting machines are constantly changing.
