The Canadian company 'Egar Tool & Die Ltd.', installed a servo transfer system to a 1200-ton Blow press, enabling the stamper to do a mix of progressive- and transfer-die jobs for the automotive industry. The LTS-2000 transfer unit at Egar mounts on the front and rear of the press, navigating parts through a 180 by 84 in. press bed. It features servo-motor control of all axes, allowing for high transfer speed and accuracy and retracts up and out of the way for simple access for die changeover and tool adjustment. Also included in the transfer-system package are a touchscreen control, a master encoder feedback and a programmable part detection. Computerized tool-recipe storage allows to change out transfer jobs quickly, important considering that the typical job run is about 5000 pieces. Egar runs automotive parts exclusively on the transfer setup, including a new job that entails 400,000 pairs of spring-hangar parts annually. Material thickness typically runs 3 to 4 mm with some below 1 mm. Stampings consist more and more of high-strength low-alloy steels. But also 50-ksi material, and a crossmember from 80-ksi material are used.
