Automatic cleaning batch seam sand burning technology for casting part main runner

Abstract

The invention belongs to the field of casting part sand removing processes, and discloses an automatic cleaning batch seam sand burning technology for a casting part main runner. According to the automatic cleaning batch seam sand burning technology for the casting part main runner, a runner cleaning tool is utilized, and the sand blasting and vibrating processes are combined. The technology comprises the following steps of conducting surface sand removing treatment, using the sand vibrating technology for shot blasting, cleaning arbors, punching a hole with an electric drill with the drill bit, chopping off the arbors with an iron chopper, clamping out the arbors with a clipper, removing main runner burrs, cleaning the bent runner arbors, blowing off one bent runner arbor with oxygen, removing black sand inside the runner, beating a casting part with an iron hammer, enabling the sand inside the runner to flow out through vibration, then conducting secondary sand vibration and shot blasting, and conducting endoscopy. The automatic cleaning batch seam sand burning technology has the advantages of being reasonable, convenient to operate, applicable to the casting part with the complex runner, good in sand removing effect and the like.

Description

technical field [0001] The invention relates to a technology for automatically cleaning and batching seam sticking sand in a casting main channel in the field of casting sand cleaning process. Background technique [0002] At present, in the foundry field, the cleaning of sand cores is a technical difficulty in the foundry industry. The cleaning of sand cores directly affects the quality of castings. Regarding the cleaning of sand cores, the current common methods are sand blasting and sand vibration. Sand blasting is heated by heating. The resin layer of the sand core is destroyed to achieve the purpose of cleaning the sand core; the vibrating sand is to destroy its adhesive force under a certain frequency of vibration, so that the sand will fall to achieve the purpose of sand cleaning, although sand blasting and vibrating Sand can clean most of the sand cores, but the traditional sand blasting and vibrating process cannot clean the sand cores and core bones in the flow...
