把产品做成可调参数的结,这对我们并不陌生。做成可调参数结构的机械设备屡见不鲜,微震压实造型机和其他铸造设备一样,常被人看成为粗糙的机械,因此可调参数结构的设计和研究常为人们所忽视。然而,大量的试验报告和研究论文都已表明,造型机紧砂效果的好坏、生产率的高低、经济效益的多少是和造型机特别是和震击机构的参数即进气行程、膨胀行程、余隙高度、弹簧刚度及安装高度、气垫高度、震铁重量、进排气口面积、气垫及震击进气压力、震击时间等设计、选取和组合密切相关。理论与实践均已表明,一旦某个参数偏离设计范围或参数组合的特性系数被破坏,机器的功能将明显下降甚 It is no stranger to us to make the adjustable knot for the product. It is not uncommon for micromechanical compaction molding machines to be made into rough mechanical structures, like the other foundry equipment, so the design and research of adjustable parameter structures are often overlooked. However, a large number of test reports and research papers have shown that the effect of tight sand molding machine, the level of productivity, economic benefits and the molding machine, especially the shock mechanism and the parameters that intake stroke, expansion stroke, Clearance height, spring stiffness and installation height, air cushion height, weight of seismic iron, intake and exhaust area, cushion and shock intake pressure, shock time design, selection and composition are closely related. Both theory and practice have shown that once a parameter deviates from the design range or the characteristic coefficients of the parameter combination are destroyed, the function of the machine will be significantly reduced
