Problems solved by technology

Since the low-melting-point alloy and the hot oil will be mixed together during the melting process of the low-melting-point alloy, when the guide vane 1 is taken out, the hot oil may remain in the cavity channel of the airfoil 12, thereby lead to residual low melting point alloy

Abstract

The invention discloses a cleaning device for a low-melting-point alloy in an inner cavity of a hollow blade. The cleaning device comprises an oil barrel, and the bottom of the oil barrel is connected with a cooling tank through a pipeline with a valve; the cooling tank is connected with a heater with an oil pump through a pipeline; a spraying hole is formed in the side wall of the oil barrel; a liftable and rotatable mounting disc is arranged above the oil barrel; the mounting disc comprises a mounting ring connected by supporting ribs; the mounting ring is provided with multiple mounting racks used for clamping the blade; the mounting disc is connected with a coaxial stirring shaft capable of rotating in the reverse direction; the mounting disc and the stirring shaft are connected in a sleeving manner; the stirring shaft is provided with multiple stirring blades; and the stirring blades are below the mounting ring. According to the cleaning device for the low-melting-point alloy in the inner cavity of the hollow blade, on the one hand, the removal time for the low-melting-point alloy is effectively shortened, and besides the purpose that the blade inner cavity subjected to removal operation is free of residues can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a device for cleaning and removing low-melting-point alloys from the inner cavity of a hollow guide blade of a gas turbine engine. Background technique [0002] figure 1 It is a structural schematic diagram of a guide vane of a gas turbine engine, figure 2 for another angle figure 1 Schematic diagram of the structure of the guide vane, see Figure 1-2 As shown, the guide vane 1 is composed of three parts: an outer edge plate 11, a blade body 12, and an inner edge plate 13. The blade body 12 is provided with a trailing edge hole, and the middle part of the outer edge plate 11 is provided with an outer edge cavity. The middle part of the inner edge plate 13 is provided with an inner edge cavity, and the blade body 12 is provided with a cavity channel connecting the trailing edge hole, the outer edge cavity, and the inner edge cavity, [0003] In the process of processing the o...
