Abstract

The invention relates to a method and a device for improving the quality of casting holes of a main oil pipeline of a machine body. The method comprises the following steps: by adopting a film-coating sand core as the sand core of the main oil pipeline of the machine body, brushing alcohol coating on the surface, and igniting the alcohol coating on the surface of the sand core of the main oil pipeline of the machine body; fixing a core at the driving end, rotating a rotary wheel at the driving end to enable the sand core of the main oil pipeline of the machine body to rotate, and winding the sand core of the main oil pipeline of the machine body by a high-temperature-resistant adhesive tape; putting the sand core of the main oil pipeline of the machine body on core seats at the two ends, measuring the wall thickness around the sand core of the main oil pipeline of the machine body, putting two four-layered first casting iron core supports at the lower part of the sand core of the main oil pipeline of the machine body and putting three four-layered second casting-iron core supports at the upper part of the sand core of the main oil pipeline of the machine body; guiding a gas discharging rope of the sand core of the main oil pipeline of the machine body out of a sand mold by a preserved cavity, covering the cavity by using resin, and enabling a great amount of gas generated by the sand core of the main oil pipeline of the machine body in casting to be discharged smoothly by the gas discharging rope.

Description

technical field [0001] The invention relates to the field of casting quality control, in particular to a method and a device for improving the casting hole quality of a main oil channel of a machine body. Background technique [0002] At present, the quality of the main oil passage of the airframe directly affects the performance of the airframe, and the main oil passages of many large airframes are formed by casting holes. Defects such as trachoma, blowhole, iron-clad sand, and bending of the main oil passage are prone to appear in the casting hole of the main oil passage, which makes cleaning difficult, directly affects the quality of the main oil passage, and even causes the machine body to be scrapped if the defect is serious. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating in order to create a method and device for improving the quality of the casting hole of the main oil channel of the body with a new structure, so t...
