Abstract

The invention discloses a method for cleaning a pipe fitting before electroplating, and belongs to the technical field of machining. The cleaning method comprises the steps that the pipe fitting is heated; after the pipe fitting is cooled, the pipe fitting is subjected to acid pickling; the pipe fitting obtained after acid pickling is subjected to first-time washing; the pipe fitting obtained after first-time washing is subjected to neutralizing treatment; the pipe fitting obtained after neutralizing treatment is subjected to second-time washing; and the pipe fitting is blown dry. By means ofthe method, the pipe fitting is cleaned before electroplating under the situation that the quality of the pipe fitting is not influenced.

Description

technical field [0001] The invention belongs to the technical field of processing, in particular to a method for cleaning pipe fittings before plating. Background technique [0002] Before electroplating metal pipe fittings, it is necessary to clean the pipe fittings before plating to remove various impurities and oil stains on the surface of the pipe fittings. [0003] Generally speaking, before the pipe fittings are stored in the warehouse, the surface of the pipe fittings needs to be coated with anti-rust oil. If the pipe fittings are stored in the warehouse for a long time, the anti-rust oil will form a chelate on the surface of the pipe fittings. The chelate is very difficult to clean, and usually needs to be cleaned by means of polishing, sandblasting, etc. to polish the surface of the pipe fittings, which not only takes a long treatment period, but also damages the pipe fittings, resulting in a decline in the quality of the pipe fittings.
