F418 Gas springs find increasing use in large press tools - in the sole role of aiding theier storage and production preparation. The springs are bolted to either the upper or lower bolsters. They are activated only when the tool is being taken out of the press. Application examples 1 and 2 show that special spacer caps are inserted prior to the tool being let down onto the gas springs – this being done whilst still in the press. During removal from the press and subsequent storage, the springs will keep the top tool elevated. Storage stop pins are provided next to the springs; when tools are stacked one on top of the other, the increasing mass will force the springs to recade – and the tops will eventually abut against the storage pins. Once the stack is removed, the springs take over adain and push the top tool up. With the usage of 4 gas springs, for example upper die parts with a weight up to 20 tons can be held high. Upon being prepared for production, the springs facilitate access to the tool. Once back in the press, the spacer caps are removed and the storage springs remain inactive during the production run. It is recommended to affix warning signs to the tools in a prominent position: the presence of gas springs in the tool often cannot be seen from the outside. Gas springs facilitate tools storage and tools preparation for production APPLICATION EXAMPLES
