Eight tonne load driven into oven
Aluminium engine blocks can develop residual stresses due to differential cooling during the casting process. This can cause the distortion of critical features during machining and make it difficult to maintain dimensional tolerances. To remove these stresses, many manufacturers heat treat their cast engine blocks prior to machining, a process that effectively relaxes the metal. It is for this purpose that the Aerotherm Group was commissioned by Ryobi Aluminium Castings in Northern Ireland to design and produce a stress relieving oven. Essential to the design of this system is the mechanism which pushes the carriage or skillet of engine blocks into the oven for heat treatment and out again at the end of the four hour cycle.
With a static load of 8 tonnes the chosen push/pull mechanism needed to be exceptionally strong and withstand high temperatures without substantially increasing the footprint of the overall system. The Framo Morat range of products was a clear front runner given these parameters, resulting in Aerotherm working with the UK distributor RA Rodriguez on the design and specification of the optimal mechanism.
Two Framo Morat products combine to provide the ideal solution for this application. They are a Framo 60PSG Linear Chain which is driven by an AG160 Compacta geared motor. A Framo Chain guide was also supplied by RA Rodriguez and shipped separately for early installation on the factory floor.
"The Linear Chain system on the stress relieving oven at Ryobi is working very well," confirms Aerotherm's Dave Taylor. "And with the help of RA Rodriguez we have also been able to retrofit a higher powered motor that enables the system to drive the 8 tonnes load at a greater speed."
