Abstract

The invention discloses a method for electroplating an elbow bend and a method for preparing a large-curvature multi-dimensional complicated metal pipe, relates to an electroplating method and a method for preparing a large-curvature metal pipe, and aims to solve the problems that a large-curvature elbow bend plated part cannot be electroplated by the conventional electroplating method and the large-curvature metal pipe cannot be prepared. The method for electroplating the elbow bend comprises the following steps of: electroplating the inner side of the elbow bend of a module to be plated by using an anode electroplating plate of which the tip is a sharp corner and the tail end is parallel to the module to be plated, and electroplating other surfaces, wherein the angle of the formed sharp corner is smaller than an included angle of the elbow bend of the module to be plated. The method for preparing the large-curvature multi-dimensional complicated metal pipe comprises the following steps of: preparing an electroplating rod, performing surface chemical treatment, electroplating by the method for electroplating the elbow bend to obtain the electroplating rod with a copper-plated surface, and removing the internal electroplating rod to obtain the large-curvature multi-dimensional complicated metal pipe. The invention is mainly used for electroplating the elbow bend and preparing the large-curvature multi-dimensional complicated metal pipe.

Description

Technical field [0001] The invention relates to a method for electroplating and a method for preparing a metal tube with large curvature. Background technique [0002] In order to reduce fuel consumption and carbon dioxide emissions, the integration and lightweight of automobiles and aerospace vehicles have become one of the focuses of attention. Studies have shown that for every 100kg reduction in vehicle kerb weight, fuel consumption per 100 kilometers can be reduced by 0.3 to 0.6L. In addition, with the continuous improvement of high-speed and high-maneuverability requirements of modern aircraft, aero engines must meet the needs of new generation aircraft with high thrust-to-weight ratio, ultra-high speed, high altitude, long endurance, and ultra-long range. Airborne equipment is very demanding on its structural weight, and the structure of aero engines is becoming more and more complex, and the requirements for accuracy are getting higher and higher. The structural design i...
