气流冲击实砂是近期国外发展起来的一种新型实砂工艺,已引起国内外铸造界极大重视。我国自行设计的气冲造型机也即将问世。由于气冲实砂过程中砂箱要承受气压与砂压,根据压力容器安全监察规程总则第三条所述,气冲造型所用砂箱实际上已是一种压力容器,因而它不能简单地延用一般砂箱。气冲造型机砂箱设计已成为急待解决的问题。本文通过对砂箱受力分析及力学计算,提出了较为合理的
Impact of the impact of real sand is a recent development of a new type of real sand technology, casting industry has attracted great attention at home and abroad. China’s own air-blow molding machine is also about to come out. Since the sandbox is subjected to air pressure and sand pressure during the gas flushing of solid sand, according to Article 3 of the General Rules for the Safety Supervision of Pressure Vessels, the sandbox used for gas flushing modeling is actually a pressure vessel so it can not simply be extended With a sand box. Air-impact molding machine flask design has become an urgent problem to be solved. In this paper, through the analysis of the force of the flask and the mechanical calculation, it is more reasonable
