| 20080216550 | FORGED ROLLER - A machine, method and tooling to precision cold-form roller blanks for anti-friction bearings. The machine is a multistage progressive former using floating die cavities to enable simultaneous shaping of the ends of the roller with high accuracy and without flash. The tools and staged forming create an improved roller with an advantageous grain pattern and devoid of structural defects previously attributable to the presence of sheared end face material in the radiused corners of the blank and flash at its mid-section. | 09-11-2008 |
| 20090205397 | Quick change tool for die casting metal - A quick change tool for use in die casting. The tool includes a pair of frame plates permanently bolted into a die casting machine. A first frame plate bolted to an upper platen of the machine and a second frame plate bolted to the lower platen. Each frame or plate can include a plurality of slotted rails that form a slotted rectangular periphery groove adapted to accept a standard size periphery ear attached to an existing die. This allows a die casting operation to retrofit old dies to fit the system while also making new dies to fit. The system allows for dies to be quickly slid out of a casting machine substantially reducing set up time in a die casting operation while still allowing for a precise relocation of the dies at each change over. | 08-20-2009 |
