Embodiment approach

[0019] Preferred embodiment of the present invention is:

[0020] Using a high-power high-speed motor (19) as the power of the ultra-high-speed centrifuge, using the gearbox (20) to control the rotation speed of the vertical shaft (21), and gradually accelerating the centrifuge arm (18) to produce a centrifugal force (10g) that is more than ten times the gravity ). Rotating arm (18) long end is about 5 meters long, and metal mold (5) is installed at its end and is promptly fixed with centrifuge rotating arm (18) by bolt (17). The short end of the rotating arm (18) is about 2 meters long, and a high-frequency power supply (1) and a thermal oil temperature control box (6) are installed at its end as a counterweight, so that the rotating arm (18) is at a position where the vertical rotating shaft (21) is a fulcrum. state of horizontal balance. Vertically install the about 0.5 meter long pillar (24) below the long end of the pivoting arm (18), and the end of the pillar (24) is e...

Abstract

The invention designs a method and device for forming and casting a turbofan aviation engine blade with performance similar to that of monocrystal metal alloy materials at a time by using low-specific-gravity large-bulk non-crystal metal alloy as raw materials and simulating the work environment of an airplane engine blade ruing load operation through the adoption of the technology of integration of a high speed centrifuge, a high-frequency rapid melting furnace and a constant-temperature metal mold, and the like. The blade does not have a metal crystal structure and does not have lattice imperfection, either. The blade has the unique whole-body consistency characteristic of monocrystals. Compared with an existing alloy blade and an existing monocrystal alloy blade, the rigidity, the elasticity, the tenacity, the high-temperature resistance and the fatigue resistance are better, and one-time forming can be achieved; and the manufacturing technology is simplified, the performance is improved, and manufacturing cost is also reduced. Thus, the invention has the dual functions of new material manufacturing and new material application, belongs to the technical field of new metal materials and is suitable for producing and manufacturing various types of turbofan engines in the spaceflight and aviation field and the like.

Description

1. Technical field [0001] The present invention uses high -speed centrifugal machines, high -frequency rapid melting, constant temperature metal mold and other technologies. It has designed a low -gravity and large non -crystal metal alloy as the raw material, and the high -frequency melting is the alloy liquid.The liquid is quickly cooled to the method and equipment of the blade of the cast turbofan aviation engine in the metal mold.This method casts the leaf -based blades, although the internal metal atom arrangement of the internal metal atoms is disorderly from a micro perspective, but from a macro perspective, its internal metal atoms are evenly distributed, dense, no metal crystal structure, and there is no lattice defect., Present the consistency characteristics unique to the single crystal.Compared with existing alloy leaves and single crystal blades, this kind of alloy material -like alloy material -like alloy material has better rigidity, elasticity, toughness and high t...
