在锤模锻生产条件下如何减少加工余量、模锻斜度和余块以精化锻件,使模锻件的形状和尺寸更接近成品零件,从而提高材料利用率和减少机加工劳动量,是我国近期内模锻生产发展的重要课题。复合工艺是精化锻件的重要手段之一。复合工艺已在生产中应用几十年了,它逐步发展成熟并显示了优越性,令人瞩目。复合工艺就是利用复合模具在压力机一次行程中对已模锻过的半成品锻件进行切边、冲 How to reduce the machining allowance in the die forging production conditions, the die forging slope and the remaining pieces to refine the forging, make the die forgings shape and size closer to the finished parts, thereby improving material utilization and reduce the amount of machining work is China’s recent die forging production and development of an important issue. Composite technology is an important means of precision forgings. Composite technology has been used in production for decades, it gradually developed and showed the superiority, attracting people’s attention. Composite technology is the use of composite mold in the press during the trip has been forged semi-finished forging trimming, red
