Ultrafine metal wire continuous straightening device

Abstract

The invention discloses a metal wire straightening device; the device is simple in structure and convenient to operate; and the device consists of a fixed bracket, a metal wire traction driving wheel,a metal wire traction driven wheel, a raw material metal wire supply wheel, a straightening module fixed base plate, a straightening module fixed transverse plate, a straightening roller and a straightening roller adjusting shaft. Through replacement of straightening rollers with different parameters and adjustment of the straightening roller adjusting shaft, the adjustment of the straightening effect can be achieved, and the continuous straightening of ultrafine metal wires is finished. The device solves the problems of large size, complex structure, instable wire feeding process and unfit for small-diameter and low-hardness metal wires in a traditional metal wire straightening device. The device is suitable for straightening metal wires with diameters of smaller than 1 mm, can meet linear feeding of the metal wires, and can meet the straightening precision in the electric explosion process due to the wire terminal fluctuation range within a circle with a diameter of 2 cm when the wire feeding length is 20 cm.

Description

technical field [0001] The invention relates to an ultrafine metal wire continuous straightening device, which belongs to the field of mechanical design. Background technique [0002] The wire electric explosion method is one of the methods for preparing nano-powders with broad application prospects. The preparation principle is that the metal wire enters the explosion chamber through the straightening wire feeding device, contacts the discharge electrode plate, and after a series of complex processes such as energy transfer and transformation, the metal wire is converted into metal vapor, and then condensed to form nanoparticles. [0003] The degree of straightness of the wire and the wire diameter of the wire are two factors considered in the design of the wire straightener. The alignment degree of the metal wire in the preparation process determines the stability of the operation of the electric explosive device. The diameter of the wire determines the output of the ele...

AI Technical Summary

Problems solved by technology

The above-mentioned prior art has the function of straightening the metal wire, but there are the following deficiencies: 1. The operation of the straightening process is complicated, and the relative position of the straightening pipe needs to be adjusted manually to realize the release of stress to achieve the purpose of straightening; 2. The device only It is suitable for straightening metal wires below 0.5mm, but not for 0.5-1mm metal wires;
