在生产小批和单件异型铸件的铸造车间里,轮类和套筒类铸件约占铸件总量的30~40%,这些轮类和套筒类铸件的芯子通常是采用实样对开芯合制作的,每年需要消耗大量的木料和制造木模的工时,同时也造成芯合管理上的混乱。几年来我们采用了“常备芯合”,该芯合系由环氧树脂塑料制成,芯合共由5部分组成,如图所示。其芯合内部的尺寸如表。表中所指的是铸钢件线收
In the production of small and one-piece special-shaped castings foundry workshop, wheel and sleeve castings accounted for about 30 to 40% of the total castings, these wheel and sleeve castings are usually used to open the core Core-made production, each need to consume large amounts of wood and woodworking man-hours, but also cause the core management confusion. Over the past few years we have adopted “standing core fit”, the core is made of epoxy resin, the core consists of a total of 5 parts, as shown. Its core size with the internal table. The table refers to the cast steel line income
