Titanium alloy wire on-line heating tension straightening device and straightening method

Abstract

The invention discloses a titanium alloy wire on-line heating tension straightening device. The device comprises a driving paying-off machine, a tension frame, an induction furnace, a tube furnace, an immersion groove circulating water cooling device, a guide unit and a driving taking-up machine which are sequentially connected, wherein the tension frame is connected to a rotary encoder and a linear potentiometer, the driving paying-off machine is connected to a paying-off frequency converter, and the driving taking-up machine is connected to a taking-up frequency converter. A straightening method includes that the driving paying-off machine, the tension frame, the guide unit and the driving taking-up machine form a constant tension and constant speed system to achieve accurate and stable straightening tension and speed needed for wire straightening, and the induction furnace and the tube furnace form a preheating constant temperature system to achieve fast and efficient wire heating and guarantee a certain temperature uniformity. The titanium alloy wire on-line heating tension straightening device solves the problems of high tension fluctuation and low heating efficiency during straightening, omits manual intervention and is high in automation degree, thereby greatly improving the quality and efficiency of straightening.

Description

technical field

[0001] The invention belongs to the technical field of metal wire straightening methods. The invention relates to an online heating tension straightening device for titanium alloy wires, and also relates to an online heating tension straightening method for titanium alloy wires. Background technique

[0002] At present, for the straightening of titanium alloy wire, most of the forms are: add a tube furnace between the take-up and pay-off machines, and adjust the speed of the take-up and pay-off machines according to experience to generate a certain tension between the two Perform heat straightening. Since the straightening tension is an empirical value, whether it is large or small, the force is small, and the purpose of straightening cannot be achieved. It is necessary to straighten the wire that has been straightened in the same way; if the force is large, the diameter of the wire will shrink. Or be broken, resulting in unsatisfactory straightening effect....
