1.引言 在汽车发动机气缸体上应用压边冒口工艺还不多见,究其原因是许多工艺人员认为,在气缸体铸件上应用压边冒口很不方便,且效果不会很理想。然而根据我厂多年在气缸体铸件上应用压边冒口的实践证明,压边冒口工艺在一些气缸体上应用是可行的,且应用效果良好。 2.压边冒口在气缸体上应用的条件 压边冒口不是可应用于所有气缸体铸件的,它受到气缸体结构和浇注位置等因素的限制。对于浇注位
1. INTRODUCTION The application of crimping risers to engine blocks in automobile engines is rare. The reason for this is that many process technologists find it inconvenient to apply crimping risers to cylinder block castings, and the effect is not very satisfactory. However, according to our practice on the cylinder block castings for many years, the practice of the crimping riser proves that the crimping riser process is feasible in some cylinder blocks and the application effect is good. 2. The crimping riser in the cylinder body application conditions Crimping riser is not applicable to all the cylinder block casting, it is subject to the cylinder block structure and casting position and other factors. For pouring bit
