Theoretical Calculation and Design Research on the Supporting Roller Bearing Seat of Stamping Composite Mold
In the production and manufacturing of workpieces,due to the low production efficiency and insufficient machining accuracy of traditional single molds,composite mold structures have gradually emerged.Replacing single molds with this structure can improve machining efficiency,save manpower and material re sources,and also prevent errors caused by multiple positioning.It plays an important role in improving the machining accuracy of parts.Therefore,the article takes the roller bearing seat as the research object and designs a composite mold that integrates punching and trimming.Firstly,the theoretical calculation of the punching composite mold roller bearing seat is carried out,and the blank diameter,trimming die edge size,and punching die edge size are obtained.The external dimensions of the convex and concave molds are also separately calculated,and the punching force value is calculated.Then,the design optimization of the com posite mold was carried out,and the design methods for each structural component were proposed,aiming to provide reference for the scientific design of the support roller bearing seat mold in workpiece production and processing.
