一般铸工车间造芯工部手工操作占很大比重,劳动强度大,其中比较大的砂芯椿砂的劳动量更大,且生产率较低,质量有时不稳定,因此造芯工作的机械化(特别对中、大芯子)是很重要的.目前机械化铸工车间已有的造芯设备大都需要压缩空气,但在很多中小厂内还没有压缩空气,为了满足一般中小厂的需要,就要求—种不以压缩空气为动力的简易造芯机,为此根据上海公私合营江南钢铁厂的经验,设计了简易振实造芯机. In general, the core part of the foundry’s workshop occupies a large proportion of manual operations, and the labor intensity is large. The labor of the larger sand core is larger and the productivity is lower and the quality is sometimes unstable. Therefore, mechanization of the core work Centering, large core) is very important.Current mechanized foundry workshop existing core equipment most need compressed air, but in many small factories there is no compressed air, in order to meet the needs of small and medium-sized factories, it requires Not compressed air-powered simple core-making machine, according to the Shanghai Public-Private Partnership Jiangnan Iron and Steel plant experience, designed a simple vibrating core machine.
