Products Robotics & Motion Control Pushing and pulling heavy loads
Aluminium engine blocks can develop residual stresses due to differential cooling during the casting process. To prevent this causing machining problems, manufacturers heat treat their cast engine blocks - a process that effectively relaxes the metal. It is for this purpose that the Aerotherm Group was commis- sioned by Ryobi Aluminium Castings to design and produce a stress relieving oven. Essential to the design of this system is the mechanism which pushes the skillet of engine blocks into the oven for heat treatment and pulls it out again at the end of the cycle. With a static load of eight tonnes the chosen push/pull mechanism needed to be strong and withstand high temperatures without increasing the footprint
of the overall system. Two Framo Morat products from R. A. Rodriguez combined to provide the solution for this application. They are a Framo 60PSG Linear Chain which is driven by an AG160 Compacta geared motor. The design of the precision chain links on the Linear Chain enables it to push as well as pull heavy loads. In the maga- zine the chain is stored spirally within a narrow chamber making suitable for the Ryobi application where space is lim- ited but the maximum stroke remains long at 6.5m. The device provides high position- ing accuracy, constant stroke speed and shock-free motion. For the oven loading/unload- ing mechanism the Framo Linear Chain is complemented by the Framo Compacta slip-on geared motor. Compacta’s economical dimensions are achieved through the use of a spur and worm gear transmission combined with per- formance optimising motors. R. A. Rodriguez

For Troax it is not just important that its systems meet high safety standards, but that they are also readily available in tried and tested surface treatments - particularly hot zinc, oth- erwise known as ‘hot dipped galvanised’. The company’s galvanised product range provides corrosion protection and a coating which can withstand high levels of mechanical stress. In damp environments, unheated premises, or for outdoor use, this is the most commonly used method as it provides an even and substantial coating both internally and on inaccessible surfaces, which powder coating does not.
The company’s Machine Guarding solutions have to be adaptable for all types of envi-
ronments and customer requirements, and the new galvanised products allow Troax to fur- ther meet its customers’ changing demands. Ex-stock delivery of the galvanised machine guarding is available, providing the same delivery times as the company’s standard pow- der coated materials.
The company’s latest innovations - Rapid Fix and Smart Fix - are two machine safety systems which can be combined or used individually, and which have many features -
innovative bracket combinations, interchangeable posts and much more. Neither of these two systems nor other Troax solutions are dependent upon what type of surface treatment is used - all components are interchangeable. Troax
