缸体缸盖铸件在静压造型线上的尺寸控制

Dimensions Control of Cylinder Block and Head Produced on Static Pressure Molding Line

介绍了缸体、缸盖在静压造型线上铸件尺寸的控制方法。详细阐述了生产过程中存在的问题和解决措施,最后指出:为了避免因定位销(套)的磨损而造成铸件尺寸精度超差的情况,需要定期对工装模具的定位销(套)进行点检,随时关注工装与设备连接处的位置度及同轴度,定期对铸件的关健尺寸进行划线来监控铸件的错型情况;对有规律的错型则可采用偏心套的方式进行修正,对壁厚不足的局部区域,可采用在模样上贴补的办法来补正。

The dimension control method of the cylinder block and cylinder head produced on static pressure molding line was introduced.The problems existing in production process and their solution measures were described in detail.Finally pointed out:in order to avoid the casting dimensional accuracy exceeding standard caused by positioning pin(sleeve) abrasion,it was necessary to periodically check the positioning pin(sleeve)of the pattern toolings,pay attention to the location degree and coaxial degree of the connection between the tooling and the equipment at any time.The key dimensions of the casting were needed to be inspected by marking method to monitor the shift situation of the casting,the regular shift could be corrected by using eccentric bushing,the local areas with insufficient wall thickness could be corrected by setting pad on the pattern.
