由於利用模锻来获得零件毛坯的方法具有许多优点,因此,目前在我国应用得愈来愈广了。 用来锻出零件毛坯的锻模的质量以及使用寿命的长短不仅决定於材料的原始组织、锻模设计的好坏及机械加工,很大程度坯决定於热处理的质量和锻模的正确使用、维护等。 锻模是用来使金属变形的工 Since the use of forging to obtain parts blank has many advantages, therefore, it has been applied more and more in our country at present. The quality and service life of the forging die used for forging the blank of the part is determined not only by the original structure of the material but also by the design of the forging die and the machining process. For the most part, the quality of the heat treatment and the correct use of the die are determined, Maintenance and so on. Forging dies are used to deform the metal
