Specific embodiment
The utility model is further described with the following Examples.
A kind of pipe thermal forming device of the high tensile steel tube of the present embodiment, as shown in Figures 2 and 3, including for filling
It is heated to the shaping dies 2 of the pipe 1 of austenitizing temperature, the both ends of pipe 1 are equipped with hardening media 4, on hardening media 4
Equipped with the compression set for compressing hardening media 4.
Wherein, the shaping dies 2 include forming cavity and the compression pipe above and below forming cavity, it is described at
Type is intracavitary to be equipped with die cavity, and the compression pipe is connected with the die cavity of the forming cavity, and the pipe 1 is located in forming cavity, institute
It states hardening media 4 and compression set is respectively positioned on the compression pipe.
