锻压加工所需的加工压力,主要决定于材料的变形抗力以及加工时的各种摩擦力。对于中温加工也不例外,而且因为材料的变形抗力具有对温度的依存性,因此更为复杂。中温锻压加工的优点是由于材料被加热而降低其变形抗力,因此,较在常温加工时显著硬化的中、高碳钢、合金钢、不锈钢等易于锻压成形。如果使用适当的润滑剂,则可得到良好的制品精度。然而,这样的优点是由于选择适当的温度而综合得到的。当选定加工温度时,不仅考虑材料对温度的依存性,同时,由于材料的温度对模具的温度上
Forging pressure required for processing, mainly depends on the material deformation resistance and processing of various friction. For medium temperature processing is no exception, but because of deformation resistance of the material has a temperature dependence, so more complicated. The advantage of medium temperature forging is that the material is heated to reduce its deformation resistance. Therefore, medium-high carbon steel, alloy steel, stainless steel and the like which are significantly hardened at normal temperature can be easily forged. Good product accuracy can be achieved with the proper lubricant. However, such an advantage is due to the selection of the appropriate temperature and synthesis. When the selected processing temperature, not only to consider the material temperature dependence, at the same time, due to the temperature of the material on the mold temperature
