自由锻。指用简单的通用性工具,或在锻造设备的上、下砧铁之间直接对坯料施加外力,使坯料产生变形而获得所需的几何形状及内部质量的锻件的加工方法。 采用自由锻方法生产的锻件称为 自由锻件。
Free forging. It refers to the processing method of forgings directly using the external force between the upper and the lower anvil of forging equipment, so as to get the required geometry and internal quality by applying external force directly to the billet. Forgings produced by free forging are called free forgings.
在考虑锻造工艺时特别是***后一火的锻造时,应尽量避免在临界变形程度下进行,forging设备,以免得到粗大晶粒***。具体来说,高温下金属塑性好,forging厂商,变形抗力小,应采用远大于临界变形程度的较大变形量锻造;低温修正时采用低于临界变形程度的小变形量进行局部修整。
When the forging process is c***idered, especially when the last fire is forged, the critical deformation should be ***oided as far as , so as to ***oid coarse grain structure. Concretely speaking, high temperature metal has good plasticity and ***all deformation resistance. We should adopt large deformation amount forging far greater than critical deformation degree. When low temperature correction is used, ***all deformation below critical deformation degree should be used for local trimming.
在现代工业生产中,forging厂家,机器自由锻已成为锻造生产的主要方法,鞍山forging,在重型机械制造中,它具有特别重要的作用。而产生的锻件形状和尺寸主要由操作工的技术水平决定。
In modern industrial production, machine free forging has become the main method of forging production, and it plays a particularly important in he***y machinery manufacturing. The shape and size of the forgings are mainly determined by the technical level of the operator.
