Ultrasonic derusting and polishing wire-drawing equipment

Abstract

The invention relates to ultrasonic derusting and polishing wire-drawing equipment. The problems that an existing ultrasonic derusting device is not thorough in derusting and cannot remove oxidation layers are mainly solved. The ultrasonic derusting and polishing wire-drawing equipment is characterized in that a first derusting device (5), a second derusting device (6) and a third derusting device(7) are sequentially arranged on a support (1) between a fine round steel guide compacting wheel mechanism (2) and a wire-drawing die (3), wherein included angles of every two projections of the first derusting device (5), the second derusting device (6) and the third derusting device (7) on a plane perpendicular to fine round steel are 120 degrees, and the structures of the first derusting device (5), the second derusting device (6) and the third derusting device (7) are the same. According to the ultrasonic derusting and polishing wire-drawing equipment, three sets of ultrasonic vibration heads are adopted to be matched with three sets of rolling wheels for bending the fine round steel, so that the oxidation layer on the surface of the fine round steel is broken and disengaged from thefine round steel; and then the oxidation layer and iron rust are shaken off through the ultrasonic vibration heads, the ultrasonic vibration heads and the rolling wheels are arranged outside the periphery of the fine round steel in a 120-degree interval manner, the oxidation layer can be removed, and derusting is thorough.

Description

technical field [0001] The invention relates to a thin round steel (wire rod) processing equipment, in particular to an ultrasonic derusting, polishing and wire drawing equipment. Background technique [0002] Thin round steel (wire rod) is often used as raw material for some metal workpiece processing. Thin round steel (wire rod) is also called steel bar for the construction field, and its diameter is not more than 10mm. Before the thin round steel is blanked, the thin round steel usually needs to be pretreated, generally including straightening, rust removal, wire drawing, cutting and other processes. At present, there are three common methods of derusting: 1. Shot blasting derusting; 2. Pickling derusting; 3. Ultrasonic derusting. Although shot blasting can remove the rust on the surface of the thin round steel, it will also harden the surface of the thin round steel at the same time, which is not conducive to subsequent machining. Pickling and derusting will cause dama...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the existing ultrasonic derusting device does not completely remove the rust and cannot remove the oxide layer, the present invention provides an ultrasonic derusting, polishing, and wire drawing equipment. The round steel is bent so that the oxide layer on the surface of the thin round steel is broken and separated from the thin round steel, and then the oxide layer and rust are shaken off together by the ultrasonic vibrating head. Outside the circumference of the round steel, the oxide layer can be removed, and the rust can be completely removed
