摘要：

大节距260 mm单齿履带板属于异形薄板类锻件，是履带式工程机械车辆行走系统的关键部位。经过对产品特点的分析，提出了大节距单齿履带板锻造过程的工艺开发，在试验后确定了模锻工艺方案。根据产品锻造过程中受力情况和金属流动规律，设计开发出“预锻制坯”的半开半闭式模具和“终锻成形”的闭式模具，完成对单齿履带板的锻造生产。检测结果表明，锻件成形效果好，尺寸达到图纸要求，质量稳定，能够满足生产使用要求。

The large pitch 260 mm single-grouser track shoe belongs to special-shaped forging sheet category, which is the key part in caterpillar engineering machinery traveling system of vehicle. After analyzing the product characteristic, the forging process development in large pitch single-grouser track shoe was put forward and the forging scheme was determined after tests. According to the force situation and metal flow law during forging, the half-closed die of pre-forging and closed die of final-forging to produce the single-grouser track shoe were designed. After the examination, the forging has good forming effect, qualified dimension and stable quality，which can meet the production requirements.
