Problems solved by technology

The existing cleaning solutions and treatment methods for removing the above-mentioned substances generally have defects such as complicated processes. More importantly, these cleaning solutions cannot completely remove the oxide layer with the corresponding surface treatment methods.
This seriously affects the re-use of the mold, and severe cases can lead to the complete scrapping of the mold, thus virtually increasing the cost of the production enterprise

Abstract

The invention relates to the technical field of machining, in particular to a method for processing the surface of a diesel engine fuel tank machining die. The method includes the steps that 1, degreasing cotton is used to stick ethyl acetate to wipe the surface of the die, and then the die is wiped dry through dry cloth; 2, the wiped and dried die is placed into cleaning liquid preheated to 45 DEG C to be soaked for 30 minutes; 3, the die is flushed with water after being fished out till the pH value of the flushing water returns to be neutral; 4, the surface of the die is polished, and anodizing is conducted on the polished die; 5, the die is flushed with water after being fished out till the pH value of the flushing water returns to be neutral, and drying is conducted. The surface processing method is concise in operation technology, cleaning liquid soaking is the most important step, and the formula of the cleaning liquid is reasonably designed, so that the oxidation layer on the surface of the die is rapidly and effectively eliminated, the reutilization rate of the die is increased, and the production cost of enterprises is lowered.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a surface treatment method of a diesel engine oil tank processing mold. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injectio...
