棒线步进式冷床的运动分析及局部优化设计

摘要

棒线步进式冷床结构复杂，其动静齿条的齿形及床面齐头辊道的设计直接影响到轧件的成型质量。对步进式冷床进行了主轴偏心轮、动齿条框架的合成运动分析，采取了床面齐头辊道模块化悬挂、短静齿条优化设计，降低了装配累积误差量，提高了轧件成型质量。%The bar step type cooling bed structure is complex. The design of dynamic and static rack tooth profile and bed abreast roller directly affects the forming quality of workpiece. The resultant motion of spindle eccentric wheel with the rack frame in step type cooling bed were analyzed. The optimization design is taken for the bed surface abreast modular roller suspension and short static rack, the cumulative error assembly is reduced, the forming quality of workpiece is improved.
