骨架锻件是美国棉花收割机上的一个关键零件,该件空间尺寸变化大、形状复杂、检测要求严格,并且技术上要求飞边放在锻件的两侧,即分模面必须是S形分模。根据实际生产设备、零件尺寸和形状特点,对锻件进行分析,制定出合理的锻造工艺,并开发安装方便、生产效率高的锻造模具,实现骨架锻件的锻造成形,得到客户认可,实现批量生产。经生产验证,该锻造零件的精度高,成形效果好,锻件尺寸与质量的一致性好,满足锻件检测要求。
Skeleton forgings are a key part of the cotton harvester in the United States. The space varies greatly in size, complex in shape and strict in inspection requirements. It is technically required that the flash be placed on both sides of the forging, that is, the parting surface must be an S-shaped parting mold. According to the actual production equipment, the size and shape characteristics of parts, the forgings are analyzed to develop a reasonable forging process, and the development and installation of convenient and efficient production of forging dies to achieve the skeleton forgings forging forming, customer recognition, to achieve mass production. The production proved that the forged parts of high precision, forming a good effect, forgings size and quality of the consistency, to meet the requirements of forgings testing.
