液氮装配法在压力机生产中的实施应用

The Application of Liquid Nitrogen Assembly Method in the Manufacture of Press

压力机的导套通过采用液氮装配法,简化了工艺流程,保证了机床垂直度等性能,并最大限度地减少了导套装配对整机精度的影响。

The application of ＂Liquid nitrogen assembly method＂ in the guide sleeve on press has simplified the technical process, which ensures the characteristics of the machine such as the verticality and reduces the influence of assembly of guide sleeve to the precision of the whole machine as much as it can.
