Tool-Life Test in Clamp Shearing of Steel Bar and Wire

  • T. Nakagawa

At present the clamp shearing method is being used almost exclusively on pure non-ferrous metals for obtaining the smooth sheared edges of the bar but it has not been adopted for steel material because of the short life of the shearing tool. Here the tool-life tests are conducted on several kinds of low-carbon steel bar and wire, using a specially designed hydraulic clamp shearing machine, and are compared with the results for copper.
