Research progress of precise shearing separation technology for high-strength metal bars
The cutting-off process of metal bars separation is the first process for forming most mechanical parts.The traditional press-shearing and band-sawing process methods are not suitable for the efficient precision cutting of high-strength metal bars with middle and large diameter due to varying degrees of drawbacks of large cutting force,inferior section quality,low production efficiency and material waste.According to the forging equipment types and loading speed of shearing cutting-off,the precision shearing separation technologies of high-strength metal bars under the research and promotion state are divided into low-speed and high-speed types.Different precision shear-ing separation technologies were discussed from the aspects of process principle,equipment type,section quality and shearing efficiency.Compared with traditional cutting-off technology,high-speed precision shearing separation technology has higher cutting efficiency and section accuracy,and the further research direction of this technology was proposed.
