锻锤是一种最古老的锻压设备,由于它结构简单,方便灵活,在生产上应用极为广泛。但是由于它的振动、噪声以及由此带来的恶劣的工作条件,使它的应用和发展受到了一定的限制。本文仅就消除锻锤对基础的振动问题进行讨论,并在此基础上探讨建立下砧不动的新型无振锻锤的原理及其可能性。基本原理的分析我们知道,有砧锤所以有振动传给基础是由于在打击时锤头急剧的动量变化所引起的巨大冲击力P部分地传给了基础(图1—a)。基 Forging hammer is one of the oldest forging equipments. Because of its simple structure, convenient and flexible, it is widely used in production. However, due to its vibration, noise and the bad working conditions resulting from it, its application and development have been limited. This article only discusses the elimination of the problem of the vibration of the hammer on the foundation, and on this basis, discusses the principle and possibility of establishing a new type of non-vibrating forging hammer with the anvil not moving. Analysis of the basic principles We know that there is an anvil hammer so the vibration is transmitted to the foundation because the huge impact force caused by the sharp momentum change of the hammer head is partly transmitted to the foundation (Fig. 1-a). base
