为提高小型锻造厂小批量生产不同尺寸的带凸缘齿轮毛坯生产效率,提高锻件质量,介绍了压槽-展宽胎模锻造工艺和双向垫环镦挤胎模锻造工艺。这对小型锻造厂生产同类型毛坯起借鉴、指导作用。 In order to improve the production efficiency of the flanged gear blank with different sizes in small-sized forging factories and improve the quality of the forging, the slotting-expanding tire forging process and the bidirectional backing ring upsetting tire forging process are introduced. This small forging plant to produce the same type of rough from the guidance and guidance.
