Guyson has developed a 7-axis robotics-blasting machine called Model RB-9, which is specifically designed to accommodate the root section of turbine blades’ metallurgical shot peening. The RB-9 shot peener houses industrial gas turbine blades that weigh over 100 pounds and measure 36" in length.
Guyson's Robotic Shot Peener
The RB-9’s enclosure measures 48x48x48" and has a bonded rubber sheeting line to reduce noise and to protect from possible warping effects of exposure to the forceful impact of the peening shot. The wall of the blasting cabinet has an opening to install an industrial robot, Fanuc M10iA, as a 6-axis peening nozzle manipulator. The robot is isolated from the severe shot-blast surroundings by using a customized laminated fabric that closes the chamber wall.
A turntable measuring 42" in diameter is synchronized as a seventh axis of robotic motion and is used to direct the turbine blade accurately across the controlled impact treatment process.
The pressure vessel with a capacity of 6.5 cubic foot is fitted with a controller and an electronic shot flow monitor. The pressure vessel displays the real-time, standardized shot flow rate in kilograms or pounds/min at the human-machine interface (HMI). A closed-loop control is optional to control the shot flow and blast air pressure at the required levels. An engineered reclaim stack-up features a spiral separator to remove non-spherical media out of circulation. Automatic media replenishment and shot supply level sensors are also provided.
