Forging method of marine main bearing cover

According to the forging method of the marine main bearing cover, on free forging equipment, through comprehensive analysis of the structure, the material performance and the forging mechanism of the main bearing cover, on the basis of designed sizing blocks and forming dies, technological parameters are adjusted, the problem that the forging difficulty is large when a small amount of main bearing covers are produced is solved, and the production efficiency is improved. All parts of the blank are fully filled, the design requirement of the blank is met, the production cost is reduced, the production period is greatly shortened, the forging process design thought is widened, and the method is particularly suitable for the small-batch production requirement of the main bearing cover. 提供一种船用主轴承盖的锻造方法，在自由锻设备上，通过对主轴承盖的结构、材料的性能、锻造的机理进行综合分析，在设计的垫铁和成型模具的基础上，调整工艺参数，解决了少量生产主轴承盖时锻造锻造难度大的问题，使得毛坯各部分充填饱满，满足毛坯的设计要求，降低了生产成本，大大缩短了生产周期，开阔了锻造工艺设计思路，特别适用于主轴承盖小批量生产要求。
