在铸造生产中,抛丸器是进行铸件表面清理的高效率设备。一些工厂还用于铸件清砂(即除芯)甚至落砂。随着我国铸造机械化的迅速发展,它的应用日益广泛。设计新的抛丸器和改进现有的抛丸器是铸造机械化的重要课题之一。要解决这一课题,必须首先选择和确定合理的技术参数,诸如抛丸轮直径、转速以及抛丸率、功率等。而这些参数是在弹丸的运动学和动力学分析基础上(经过实践验证)提出来的。关于抛丸器运动学参数的计算方法,Π.H. 阿克肖诺夫曾提出过。稍后,M.M. 萨维林也进行了较详细的探讨。我们认为,
In casting production, the shot blasting machine is a highly efficient device for cleaning the surface of castings. Some factories are also used for sand casting (ie, core removal) and even sand removal. With the rapid development of casting mechanization in our country, its application is increasingly widespread. Designing a new shot blasting machine and improving the existing shot blasting machine is one of the important topics in casting mechanization. To solve this problem, we must first select and determine reasonable technical parameters, such as wheel diameter, speed and shot blasting rate, power and so on. These parameters are based on the projectile kinematics and dynamics analysis (proven) put forward. On the blasting machine kinematics parameters of the calculation method, Π.H.Akashonov has been proposed. Later, M.M. Saverin also conducted a more detailed discussion. We believe,
