Abstract
The invention discloses a continuous hot-drawing forming method for a nickel-titanium alloy pipe. The continuous hot-drawing forming method comprises the following steps: 1, inserting a core rod into a nickel-titanium alloy pipe blank to obtain a combined body; 2, drawing the combined body by adopting a continuous hot-drawing forming device; 3, repeating the step 2; 4, heating the drawn combined body, then plastically stretching the core rod in the combined body to reduce the diameter of the core rod, and finally taking out the diameter-reduced core rod to obtain the nickel-titanium alloy pipe. According to the method, due to induction heating, the heating speed is high; continuous hot-drawing can be realized by continuous heating, so that the production efficiency is improved; furthermore, a work hardening state on the surface of the pipe can be effectively reduced in a heat treatment stage by virtue of a skin effect of current; the subsequent plastic processing of materials is facilitated. A graphite pipe is adopted as the continuous hot-drawing forming device used in the method, and can preserve the heat of the materials and realize a lubricating function; therefore, the phenomenon that the surface of the pipe is scratched during the axial stretching motion in a furnace pipe can be effectively avoided.
