谈气冲气推成形触头造型机的开发研制

简要阐述了我国铸造机械化的现状和旧线改造的需要.介绍了一种新发明的造型机实砂机构,它于同一工位、同一工序、用同一动力,实现了气冲紧实与成形触头冲击紧实同时并举.大量实验研究表明:气冲气推成形触头造型机的实砂效果十分理想,砂型紧实度高而且均匀,完全克服了目前单纯气冲造型技术中存在的弊端,拓宽了气冲造型机的适用范围.这是一种机构简单、投资少、高速、高效、低能耗的湿型粘土砂造型实砂机构,渴望开发这一机种为我国铸造旧线改造做贡献.

Development of Air Impact Molding Machine Combined With an Air-pushed Contour Squeeze Head

The present status of China foundry mechanization and the need for old production - line reform are summarized. A kind of new molding machine, which was recently invented, is demonstrated. For the machine, air impact compaction and impact compaction of the air-pushed contour squeeze head are simultaneously carried out, and these two types of compaction are performed at the same working place, in the same working procedure, and with the same compressed air power. The experimental results indicate that the sand compaction effects of this new type of air impact molding machine are ideally perfect, high and uniform mold compactbility being obtained. This new air impact molding machine completely overcomes the disadvantages of the present single air impact molding machines, and greatly extends the application scopes of air impact molding technology. And it is a new molding machine of simple design, high speed, excellent efficiency, lower energy consumption and smaller investment The author thirsts to develop this kind of foundry machine to make contributions to China foundry old production-line reform.
