Document Type and Number:
WIPO Patent Application WO/2021/036713
Kind Code:
A1
Abstract:
A relative sliding-less superfine metal or alloy wire drawing apparatus, comprising: a wire releasing system (1), the wire releasing system comprising a wire releasing wheel, a guide wheel (13), a first wire guiding wheel (14) and a speed regulating apparatus which are arranged sequentially, the speed regulating apparatus being used for controlling the wire releasing speed of the wire releasing system; a wire drawing system (2), the wire drawing system being connected to the wire releasing system, the wire drawing system comprising a heat treatment wheel (21) and a plurality of sequentially connected wire drawing units, speed regulating apparatuses also being arranged in the wire drawing units; a wire receiving system (3), the wire receiving system being connected to the wire drawing system, the wire receiving system comprising a wire receiving wheel, used for recovering drawn wire. The speed of wire drawing wheels (28) in the wire drawing units of the apparatus is adjustable, and there is no relative sliding between any wire drawing wheels. The present invention implements sliding-less drawing of superfine metal or alloy wire, eliminates wire surface defects, and has a low wire drawing die proportioning ratio accuracy, high wire drawing device versatility and low maintenance costs.
