PURPOSE: An auto center-aligning device is provided to automatically align centers of dies by using unbalance of force applied to each die while a wire drawing process is being carried out. CONSTITUTION: An auto center-aligning device includes a die installing section(10), two cylinders(20,30), and a flowrate adjusting section(40). A wire drawing die(11) is installed on the die installing section(10) in such a manner that the wire drawing die(11) is moved by means of force applied from a wire(12). The cylinders(20,30) are installed at both sides of the die installing section(10) and are communicated with each other such that pistons(21,31) accommodated in the cylinders(20,30) are moved according to a movement of the die installing section(10). The flowrate adjusting section(40) is positioned in a connecting path(41) formed between the cylinders(20,30) so as to control variation of fluid.
