A Study of the Mechanics of Closed-die Forging. Important Factors in Selection and Use of Equipment for Forging

摘要

The increasing degree of sophistication observed in the forging industry requires a sound and fundamental understanding of equipment capabilities and characteristics. The equipment behavior influences the forging process since it determines the feasibility of forging a part and it affects the rate of deformation and the temperature conditions. The load and energy requirements of a given forming process must be compatible with the load, energy, time and accuracy characteristics of a given forging machine. The report discusses the important and basic characteristics of hydraulic presses, mechanical-crank- or eccentric-type presses, screw presses and hammers. The equipment behavior is considered in relation with the forging process. (Author)
