Problems solved by technology

Due to the existence of the core or the complex structure of aviation blades and complex structures, the corresponding cavity structure of the shell is more complicated. Closed structure, water or alcohol can only be injected in one direction, and the flow rate is very slow, and the larger sand particles in the shell are not easy to wash away. At the same time, water or alcohol must be injected first and then flow out. The blade type with core Shells or shells with complex thin-walled structures have complex circuits and narrow areas. Liquid injection may easily cause debris such as flashes and sand to rush into the narrow cavity of the shell and be caught, and it is difficult to clean out the debris.
At the same time, water or alcohol will soak the mold shell and the core inside the mold shell, and the mold shell needs to be heated and dried twice, which is cumbersome to operate and low in production efficiency.
In addition, when clear water or alcohol is used to clean the shell containing the core, the moisture contained in the liquid may form crystal water with some components in the active core of the shell. During the pouring process of the shell, the crystal water precipitates, causing the casting Metallurgical defects such as pits

Abstract

The invention discloses a blowing-suction integrated cleaning device for an aviation blade and a complex component mold shell. The blowing-suction integrated cleaning device is composed of a vortex inlet mechanism (1), a gas loop control mechanism (2), a blowing-suction head tube (3) and a blowing-suction mouth head (4); the blowing-suction head tube (3) is provided with two parallel gas circuitswhich are the main gas circuit and the branch gas circuit; the blowing-suction mouth head (4), the tubular main gas circuit in the blowing-suction head tube (3) and the vortex inlet mechanism (1) arecoaxially and sequentially connected; and the gas loop control mechanism (2) is simultaneously connected with the branch gas circuit of the blowing-suction head tube (3) and the vortex inlet mechanism(1). The invention further discloses a blowing-suction integrated cleaning method for protecting the aviation blade and the complex component mold shell. According to the blowing-suction integrated cleaning device and method, the percent of pass of casting can be effectively improved, and the blowing-suction integrated cleaning device and method have predictable huge economic value and social value.

Description

Technical field: [0001] The invention relates to the technical field of cleaning and application of aviation blades and complex components, and in particular provides a blowing-suction integrated cleaning device and cleaning method for aviation blades and complex component shells. Background technique: [0002] In the prior art, non-metallic inclusions caused by unclean cavity cleaning account for 30%-60% of the total waste loss of aviation blades and complex structural parts castings, which is a technical problem that needs to be solved urgently. [0003] Floating ash, falling off flash and other substances in the cavity of aviation blades and complex structural parts are the main causes of non-metallic inclusion defects in castings. Due to the existence of the core or the complex structure of aviation blades and complex structures, the corresponding cavity structure of the shell is more complicated. Closed structure, water or alcohol can only be injected in one direction,...
