高速大功率柴油机的控制摇臂、排气摇臂和进气摇臂等零件,形状复杂,非加工面多,工作时处于高速运动状态,受交变载荷作用。为了达到一定的机械性能和加工质量,尽量减少切削加工面,要求模锻成形。因此,如何设计好锻模,保证质量,达到高生产率和良好的经济效果,是本文要探讨的问题。在复杂叉形锻件的锻模设计中,制坯方案的选择和制坯型槽的设计,是问题的关键。这方面,在《模锻及模具设计》(以下简称《模锻》)一书中,提供了一般的方法和准则。但是对于一些特别复杂的模锻件,如果仍然照搬《模锻》的方法和准则,往往会使工艺过程繁琐,甚至锻不出合格的锻件来。这就要求在某些
High-speed high-power diesel engine control rocker, exhaust rocker and intake rocker and other parts, complex shape, non-processing surface and more work in high-speed movement, subject to alternating load. In order to achieve a certain degree of mechanical properties and processing quality, minimize cutting surface, requiring forging forming. Therefore, how to design a forging die, to ensure the quality, to achieve high productivity and good economic results is the issue to be explored in this article. In the forging design of complex fork forgings, the choice of billet design and billet groove design is the crux of the problem. In this respect, general methods and guidelines are provided in the book “Die Forging and Die Design” (hereinafter referred to as “Die Forging”). However, for some particularly complex forgings, if still copy the “forging” methods and guidelines, often make the process cumbersome, or forging out of qualified forgings. This requires some
