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 resulting in residual low-melting-point alloys

Abstract

The invention discloses a device for removing low-melting-point alloy from the inner cavity of a blade. The device comprises an oil tank; the bottom of the oil tank 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 opening is formed in the side wall of the oil tank; a mounting disc which can lift and rotate is arranged above the oil tank; the mounting disc comprises a mounting ring which is connected through supporting ribs; the mounting ring is provided with a plurality of groups of mounting frames which are used for clamping blades; after the blades are clamped by the mounting frames, the overall height of the mounting ring and the blades thereon is 1 / 10 of the height of the oil tank. According to the device for removing the low-melting-point alloy from the inner cavity of the blade provided by the invention, on one hand, the low-melting-point alloy removal time is effectively shortened, and on the other hand, no residue on the inner cavity of the blade which is subjected to a removal operation is also effectively guaranteed; in addition, a low-melting-point alloy removing operation can be performed continuously in batches; the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a device for removing low-melting-point alloys from the inner cavity of a hollow guide vane 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 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 121, and the middle part of the outer edge plate 11 is provided with an outer edge cavity. 111, the middle part of the inner edge plate 13 is provided with an inner edge cavity 131, and the blade body 12 is provided with a cavity connecting the trailing edge hole 121 with the outer edge cavity 111 and the inner edge cavity 131. lumen channel, [0003] In the process of process...
