皮带松砂机是一种比较常见的松砂设备。移动式皮带松砂机比较灵活,特别适用于生产场地分散的铸造车间。目前国内生产的皮带松砂机型号很少,而且存在不少问题。尽管有些单位对现有皮带松砂机进行了一些改进,但是在松砂效果、松砂机参数选择等方面,还缺乏实验数据。为了合理地选择皮带松砂机的参数,克服现有皮带松砂机的缺点,寻求一种新型皮带松砂机,我们做了一些试验,并在此基础上设计制造了一台双级松砂机。经工厂使用,效果很好。一、皮带松砂机参数选择试验试验是在生产用的松砂机上进行的。主要进行了以下试验:不同倾角对抛射距离的影响;前置调距板倾角对抛射距离的影响;不同转速 Sling loose belt is a more common loose sand equipment. Mobile belt sanding machine more flexible, especially for the production site scattered foundry. At present, the domestic production of loose belt sands model is small, but there are many problems. Although some units have made some improvements to the existing belt sanding machines, there is a lack of experimental data on the effect of sanding and the parameters of sanding machine selection. In order to select the parameters of belt sanding machine rationally and to overcome the shortcomings of the existing belt sanding machine and to find a new type of belt sanding machine, we did some experiments and based on this, designed and manufactured a two-stage sanding sand machine. Used by the factory, the effect is very good. First, the parameters of the belt loose sand machine test is selected in the production of loose sand machine carried out. Mainly carried out the following tests: different tilt angle on the impact of the projectile distance; pitch tilt effect on the projectile distance; different speeds
