AUTOMOTIVE CROWN WHEELS BLASTED
Components are robotically loaded in automated cell process
A Guyson Multiblast® RXS 900 blast system has been installed by one of the world's leading manufacturers of powertrain technology to accurately blast etch two sizes of case hardened automotive crown wheel components after phosphating. The original installation was manually loaded and unloaded and, after an initial proving period, it successfully progressed to a totally automated cell, where it is robotically loaded and unloaded.
The Guyson RXS 900 blast cabinet is fitted with an indexing rotating turntable with six evenly spaced revolving work spindles which index through the process area, presenting the components accurately and for a precise length of time in front of the blast guns. Blasting takes place at two of the six spindles, which are positively driven by a toothed belt to ensure an even blast coverage during rotation of the component. The machine is equipped with three model 900 and three model 400 blast guns (although not all guns are used all of the time), mounted on fully adjustable arms.
The components are loaded onto the first spindle when the vertically sliding pneumatic door opens. The turntable then indexes twice round to the first blast station where a model 900 gun lightly blasts the internal bore of the component with glass bead media at low pressure to remove light oxidation.
The turntable then moves further round to the next blast station where a pneumatically operated rotating bore mask descends and seals off the internal bore to prevent it from being over-blasted, whilst allowing the flat top of the gear to be blasted with two model 400 guns to remove a further ring of oxidation. The component then indexes around into an air-wash compartment, where any residue blast media is removed, and finally reaches the unload position.
The system is completed with a model CY600-16 Cyclone Reclamator, connected to the cabinet with rigid polyurethane ducting, and a GC20-K5 reverse jet pulse cleaning dust collection unit, supplied with secondary filter and pressure differential control on the secondary filter. The dust collection bin incorporates a wheeled waste media unit designed for ease of moving and lifting with a fork lift.
