一、前言落砂机是铸工车间常用设备之一,但落砂效果不好是国内落砂机使用中存在的主要问题,主要原因是设计计算方法很不完善,甚至对栅床运动影响较大的因素,如负荷对栅床的冲击激振,在国内外的落砂机设计中也都未考虑,本文通过理论分析和试验测试的方法来获得达到理想落砂效果所要求的结构和工艺参数,从而得出惯性式振动落砂机的合理的设计计算方法。
First, the preface Falling sand machine is one of the commonly used equipment in the foundry workshop, but the poor effect of falling sand is the main problem in the use of the domestic falling sand machine. The main reason is that the design calculation method is very imperfect and even has a great influence on the movement of the gate bed Of the factors such as the impact of the load on the gate bed excitation, the design of the sand machine at home and abroad are also not considered, this paper through the theoretical analysis and test methods to achieve the desired results to achieve the desired effect of falling sand structure and process parameters , So as to get the reasonable design and calculation method of inertial vibrating sand drop machine.
