冲击作用的锻压机械,在金属塑性变形设备的产品数量及产品品种方面,都占有极重要的地位。其中包括:各种形式的锻锤、摩擦压力机,以及一些实验室设备——传动落锤、带自由下落锤头的落锤。这类机器正在不断地发展和改进。例如,最近在实际中已解决了消除蒸汽——空气模锻锤基础的振动问题,从而消除了它们的一个主要缺点——对周围介质的有害的振 Impact forging machinery, plastic deformation in the metal product number and product variety, both occupy a very important position. These include: various forms of forging hammers, friction presses, and some laboratory equipment - drive drop hammers, drop hammers with free fall hammers. Such machines are constantly evolving and improving. For example, vibration problems that have eliminated the base of steam-air forging hammers have recently been solved in practice, thereby eliminating one of their major drawbacks - detrimental vibrations of the surrounding medium
