SCHROTSTRAHLSYSTEM UND VERFAHREN ZUM SCHROTSTRAHLEN

摘要

Consistency in shot peening is obtained by a system which uses a force sensor to sense the reaction force from a shot peening gun in combination with a magnetic densitometer sensing coil disposed at the outlet of the nozzle of the shot peening gun. A signal representative of the reaction force due to the ejected shot and a signal representative of the ferromagnetic shot within the sensing coil are used to calculate the average shot particle velocity and the mass flow rate. Additionally, alarm circuitry is provided to ensure that the system is properly operating.
