Numerical design of a new forging press drive incorporating non-circular gears:

AbstractManufacturing processes as well as products have to be improved continually to meet all the requirements of international competition. Along with economic demands, changing consumer and environmental legislation lead to increased pressure for new and advanced products and processes. Consequently, the forging industry continually tries to improve hot forging processes. Precision hot forging technology, used for the production of connecting rods, bevel gears, straight planet gears, helical gears, clutch gearing or constant velocity joints, has been improved constantly [1–3]. Precision forging is carried out with closed dies in order to guarantee the continuous quality of the workpiece and to avoid possible damage to the forged parts by clipping or piercing operations. Many variables influence the quality of the final product and the economics of the process, especially the workpiece temperature, the die temperature and the pressure dwell time. High workpiece temperatures lead to high temperatures on...
