Description
Technical Field
The invention belongs to the technical field of wiping corrosion, and particularly relates to a rotating member wiping corrosion workbench.
Background
The wipe corrosion process is widely used in the aerospace industry for localized corrosion of metal parts. The amount of single-side metal removed by wiping corrosion is about 0.0025-0.0051 mm. Meanwhile, corrosion pits and intergranular corrosion cannot be formed on the surface of the metal. Generally, the process is performed before fluorescence detection to remove substances such as oxide scale and the like which affect fluorescence detection, and fluorescence detection should be performed immediately after wiping corrosion is completed.
The wiping corrosion process is suitable for most metals, such as titanium alloy, aluminum alloy, high-temperature alloy and stainless steel. The method comprises the steps of using corrosive solutions with different formulas for different metal materials, polishing a to-be-corroded area before wiping, using deionized water to clean a corroded part after polishing, then using the deionized water to wash the part to remove the corrosive solutions, and using compressed air to blow the part dry.
The traditional wiping corrosion process involves multiple steps and requires more tools. Grinding is usually arranged in a clinch-repair section, cleaning is arranged in a surface treatment section, and finally the blow-drying process requires transferring the parts to a place where compressed air is present. Parts are repeatedly turned over in the machining process, so that the machining efficiency is low, and the parts are easily damaged by collision in the turning over process.
Disclosure of Invention
Aiming at the problems in the prior art, the method provides the special workbench for wiping corrosion of the metal parts, integrates all tools and medicines in a wiping corrosion link, and structurally comprises an operation turntable, a multidirectional adjusting lamp, a cleaning tank, an air exhaust device, a storage tank, a compressed air spray gun and a deionized water spray gun. All the processes of wiping and corroding can be finished on the workbench.
Furthermore, the workbench is made of stainless steel and polypropylene, and the surface of the stainless steel is coated with anticorrosive paint to resist the corrosion of wiping corrosive liquid to the workbench.
Furthermore, the turntable is used as an important platform for wiping corrosion, and the processes of incoming inspection, organic solvent oil removal, polishing, corrosion and inspection are all carried out on the turntable. The rotary table is designed to be embedded, so that the operating platform and the rotary table are on the same plane, and the boss is prevented from knocking and damaging parts.
Furthermore, a cleaning tank is designed in a part cleaning area, water marks of parts are prevented from splashing to the operating platform and the rotary table in the cleaning process, and meanwhile, a compressed air spray gun and a deionized water spray gun are installed on the right side of the working table, so that the parts are guaranteed to be processed in time.
Furthermore, the upper part is provided with an illuminating lamp with illumination capable of being adjusted in multiple directions, so that the sufficient illumination intensity is ensured when an operator and an inspector operate.
Furthermore, four storage lattices are arranged below the operating platform and are respectively used for storing corrosive solution, polishing and repairing tools, labor protection articles and glassware.
Furthermore, an air exhaust device is arranged above the workbench to remove volatile acid and other harmful substances in the corrosive liquid.

Detailed Description
The invention is described in detail below with reference to the following figures and examples:
example 1: the invention is used for wiping and corroding the corrosion workbench, firstly, the parts are inspected, organic solvent is used for removing oil, the surface to be treated is polished and repaired, wiping and corroding are carried out, the parts are cleaned and dried, and then inspection is carried out.
The method comprises the following specific steps:
(1) placing the part on a turntable of a workbench, and after the part is inspected, removing oil from the part by using acetone to remove oil stains on the surface of the part;
(2) taking out the sand paper from the storage lattice of the operation table to polish and repair the surface to be corroded;
(3) placing the part in a water tank, cleaning the part by using a deionized water gun, and drying the part by using compressed air after cleaning;
(4) taking out the corrosive solution, the wood bar, the clamp and the beaker from the storage lattice for work preparation;
(5) place the part on the carousel, adjust light and guarantee that the surface of treating to corrode has sufficient illumination intensity, open updraft ventilator. Pouring a small amount of corrosive liquid into a clean chemical-resistant measuring cup or vessel to serve as a working solution, clamping the wiping cotton soaked with the corrosive solution by using a wooden clamp, wherein the amount of the dipped solution is required to ensure that the wiping cotton does not flow to other surfaces in the wiping process and the surface to be corroded is sufficiently corroded. The time is carried out according to the corresponding technical schedule. The corrosion should be continuous and complete during operation;
(6) after etching, the parts are placed in a water tank to completely clean the etching area so as to remove the residual etchant: wiping off corrosive liquid on the metal surface by using clean absorbent cotton, wiping the corroded area by using paper or cloth soaked with clean water for at least three times, and drying the part by using clean compressed air;
(7) and (4) inspecting the corrosion state of the part by an inspector, and returning to perform fluorescent inspection immediately after the part is qualified.
The use of the novel corrosion workbench is cleaned, all tools and medicines involved in the corrosion are integrated together, the working time of the corrosion is shortened, the working strength of an operator is reduced, and meanwhile, the part is prevented from being repeatedly turned over to cause the collision and scratch of the part.
