Abstract

The invention discloses a preparation method of a high-hardness silver-copper-nickel alloy conductive ring and belongs to the technical field of preparation of conductive slip rings. The preparation method of the high-hardness silver-copper-nickel alloy conductive ring comprises the following steps: (1) smelting a silver-copper-nickel alloy into an ingot, and carrying out homogenization heat treatment, forging and rolling to form an alloy plate blank; and (2) performing heat treatment and wire cutting on the alloy plate blank obtained in the step (1) to obtain the silver-copper-nickel alloy conductive ring. The high-hardness silver-copper alloy conductive ring prepared by the method does not have the phenomena of inclusions, pits, perforations, defects and the like, is uniform in texture and good in performance.

Description

technical field [0001] The invention belongs to the technical field of preparation of conductive slip rings, in particular to a method for preparing a high-hardness silver-copper-nickel alloy conductive ring. Background technique [0002] The rotating part of the radar antenna base has various driving elements, measuring elements and control elements, while the power supply and control cabinets are fixed, so a rotating connection device is required to transmit signals or power between relatively rotating parts. [0003] Conductive rings, also known as conductive slip rings, collector rings, bus rings, etc., are precision power transmission devices that realize the image, data signal and power transmission of two relative rotating mechanisms. Where there is a need to transfer power or data from a fixed location to a rotating location. The bus ring needs to transmit low-level signals, medium-high frequency signals and currents up to hundreds of amperes. Therefore, its perform...
