冲压复合模具托辊轴承座的理论计算及设计研究

Theoretical Calculation and Design Research on the Supporting Roller Bearing Seat of Stamping Composite Mold

工件生产制造当中,由于传统单模具的生产效率低下且加工精度有所不足,因而逐步诞生了复合模具结构,用此结构替代单模具能够提高加工效率,可以节约人力物力损耗,同时也能防止多次定位导致的误差,对于提高零件加工精度具有重要作用。为此,文章以托辊轴承座为研究对象,设计了一种冲孔与切边一体化的复合模具,首先进行了冲压复合模具托辊轴承座的理论计算,得出了毛坯直径、切边模刃口尺寸以及冲边模刃口尺寸,还分别求出了凸模与凹模各自的外形尺寸,计算出了冲裁力值。然后对复合模具进行了设计优化,提出了各个结构件的设计方法,旨在为工件生产加工中托辊轴承座模具的科学设计提供参考。

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.
