Reduced risk of cracks when forming an equal-pass thin-walled tee

The problem of ruptures during the forming of equal-pass thin-walled tees is described. The influence of punch shapes and technological hole on the example of weakly stamped material is estimated. The combined technology of tees production is considered, which will help to reduce the probability of ruptures.

Keywords: cracks, equel-pass thin-walled tee, technological hole, punch shape.
