Abstract
The process of knocking out castings is considered, consisting of removing hardened and chilled to certain temperature castings from the mold, which in this case is destroyed. Shaking out of castings is carried out at various knockout installations, while the main type of equipment for knocking out castings from molds is mechanical knockout grates. In order to improve the efficiency of the knockout process, the design of the foundry knockout grate has been improved. It is proposed to use a coaxial two-rotor vibration exciter of increased power as the vibration drive of the foundry knockout grate. This allows to separately adjust the frequency and amplitude of the oscillations as well as increase the range of regulation of these parameters. It was also revealed that when using this exciter, the load on the supports decreases in comparison with the unbalanced load. The computer and experimental studies of the developed vibration drive have been carried out, and the dependencies of the oscillation parameters on the tuning modes have been determined. The design of a foundry knockout grate with two-rotor coaxial vibro-exciters has been developed.
