在成批、大量生产的铸工车间,为了确保正常生产,混砂机除应满足工艺要求外,还应该是运转可靠,经久耐用和便于维修。过去我厂有两台S116混砂机,按设备的生产率计算是可以满足生产要求的,但由于该设备存在一些结构问题,经常停台检修,造成停产或减产。为确保生产正常进行,又增加了一台,但机械维修太频繁,实为我厂生产中的薄弱环节之一。为了减轻机修压力,我厂对S116混砂机原结构作了一些改进,经多年使用,证明效果很好,改进后的混砂机的结构见图1。
In bulk, mass production of the Casting Workshop, in order to ensure the normal production, in addition to sand mixer should meet the process requirements, but also should be reliable, durable and easy to maintain. In the past I plant two S116 sand mixer, calculated according to the production equipment to meet production requirements, but because of the structure of the device there are some problems, often stop overhaul, resulting in stop production or cut. To ensure the normal production, but also increased one, but the mechanical maintenance is too frequent, in fact, one of the weak links in the production of our plant. In order to reduce mechanical pressure, our factory makes some improvements to the original structure of S116 sand mixer. After years of use, the result is very good. The structure of the improved sand mixer is shown in Fig.1.
