Description

Technical Field

[0001] The invention belongs to the technical field of shell cleaning of metal castings, and particularly relates to a shell cleaning device for a casting with multi-directional swing and a working method thereof. Background Art

[0002] For various high-quality castings such as those in the aerospace and ship industries, there are quite high requirements for their internal metallurgical quality. Generally, inclusions and sand inclusion defects are not allowed. If substances such as sand, surface layer flakes, dust, silica sol, and ash of wax exist inside the casting shell before pouring, it is easy to entrain the molten metal during the pouring process, causing inclusions and sand inclusions in the casting. Therefore, it is very necessary to clean the casting shell before pouring.

[0003] With the continuous increase of production tasks, a large number of shells need to be cleaned. This not only increases the labor intensity of workers, but also affects the operation efficiency of continuous production. Moreover, with the increase in the number of shell transfer times, the operation safety and shell stability will also decrease to a certain extent, increasing the probability of shell breakage. Through previous research, a rotating system for the casting shell cleaning platform was invented and manufactured, with remarkable cleaning effects, meeting the cleaning requirements of most casting shells and greatly improving the production efficiency. However, for casting shells with extremely complex inner cavities, some parts of the shell cannot be effectively cleaned, and simply using this system cannot achieve the cleaning purpose. Therefore, researching continuous, safe, and efficient cleaning and inspection equipment suitable for casting shells with special structural dimensions is one of the key steps to achieve high-quality, high-stability mass production of high-quality castings with special structural dimensions.
