Abstract
A push-bending forming device for titanium alloy tubes is provided, which includes a die main body, a plurality of filling balls, a differential temperature assembly and a punch. The filling balls are configured to be filled in a tube blank, and are made of a metal material, with a heat-resistance temperature over 500° C. A diameter of the filling ball is less than an inner diameter of the tube blank. The punch includes a first pushing part and a second pushing part. A push-bending forming method using such device is also provided.
