Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] The surface treatment process of the engine block in the engine remanufacturing process includes the following steps implemented in sequence:

[0016] (1) Body roasting: Put the engine body into a roasting furnace for burning, so that the combustibles in the attachments on the surface of the engine body will be completely burned, and the non-combustibles will harden the nodules;

[0017] (2) Body shot blasting: Shot blasting is performed on the roasted engine body to crush the incombustibles of the engine body to achieve the purpose of cleaning the incombustibles and remove the oxide layer on the surface of the engin...

Abstract

The invention discloses a surface treatment process of an engine body in an engine refabrication process and belongs to the technical field of engine refabrication. The surface treatment process comprises the steps of firing the engine body to make combustible in attachments on the surface of the engine body burnt thoroughly and noncombustible in the attachments hardened and sintered; carrying out shot blasting treatment on the fired engine body to smash the noncombustible on the engine body, and to simultaneously remove an oxide layer on the surface of the engine body; carting out shot cleaning on the engine body; flushing the engine body by using inflaming retarding kerosene; placing the engine body in a cleaning liquid, utilizing an ultrasonic vibrator to produce ultrasonic wave for agitating water molecules and removing the inflaming retarding kerosene and greasy dirt remaining in an internal cavity of the engine body. According to the surface treatment process, the production efficiency is high, each part of the engine body can be cleaned, the process is applicable to processing on the surface of the engine body in batches, and therefore the refabrication of the engine body is facilitated.

Description

technical field [0001] The invention belongs to the technical field of engine remanufacturing, and in particular relates to a surface treatment process of an engine body in the engine remanufacturing process. Background technique [0002] Remanufacturing is an industry that implements high-tech repair and transformation of waste products. It is aimed at damaged or about to be scrapped parts. On the basis of performance failure analysis, life evaluation and other analysis, remanufacturing engineering design is carried out. Technology to restore the shape and precision of the workpiece, so that the quality of remanufactured products can reach or exceed that of new products. The engine block is one of the important parts of the engine and the most valuable part in the whole engine. The remanufacturing of airframe is of great significance to the remanufacturing of the whole engine. [0003] As a moving mechanical device, the engine requires a large amount of lubricating oil to...
