抛砂机是以高速旋转的叶片,将型砂抛入砂箱,得到紧实铸型的造型设备。它以生产率高、适应性强、直接由电动机带动,噪音小等特点而显示出它的生命力,因此得到广泛的使用。抛砂机按其抛头的进砂而分为轴向进砂抛砂机及切向进砂抛砂机两大类。在国内较为普遍地采用切向进砂的抛砂机,因此对切向抛砂机的分析与研究亦颇多注意,本文根据教学实践的经验,就切向抛砂机的抛头设计问题提出肤浅看法。全文共分三个部分,其中(一)～(六)提供了切向抛砂机抛头技术参数设计的取值资料及公式,(七)为
Sand throwing machine is a high-speed rotation of the leaves, the sand thrown into the sand box, to get tight molding equipment modeling. It is highly productive, adaptable, driven directly by the motor, noise and other characteristics of its demonstrated vitality, it is widely used. Sand throwing machine according to the first into the sand and into the axial into the sand thrown sand and tangential into the sand thrown two major categories. Therefore, the analysis and research on the tangential sand throwing machine is also paid more attention. Based on the experience of teaching practice, this paper puts forward the design of throwing head of the tangential sand throwing machine Superficial view. The full text is divided into three parts, of which (a) ~ (f) provide the tipping sand throwing machine technical parameters of the design of the value data and formulas,
