离心铸管机浇注、冷凝后的拨管是非常重要的工序,常需采用专门的拨管器来完成。因此,拔管器的工作性能(尤其是拔管力)和结构设计的合理性对机器的工作效率有很大影响。拔管力太大会涨破管壁,太小则拔不出管子。哈尔滨工业大学铸造教研室和校办工厂联 Centrifugal casting machine pouring, after the condensation of the dial is a very important process, often need to use a dedicated remote control to complete. Therefore, the working performance of the pipe puller (especially the extubation force) and the structural design rationality have a great impact on the work efficiency of the machine. Extubation will break the wall too much, you can not pull the pipe too small. Harbin Institute of Technology foundry teaching and school-run factory
