Embodiment Construction

[0020] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] Such as Figure 1 to Figure 3 As shown, the present invention provides a kind of ultrasonic shot peening strengthening equipment, which includes: ultrasonic vibration device, projectile and shot blasting chamber 1 that can accommodate projectile, projectile 4 is selected high-quality tungsten steel projectile, and the diameter of projectile 4 is 1mm-4mm . Wherein, the shot blasting chamber 1 is a cylindrical structure with a diameter of 200mm-300mm, a height of 150mm-200mm, and a wall thickness of 8-12mm. The surface of the upper port of the shot peening chamber 1 is a curved surface conforming to the surface of the fan blade 3 , and the lower end of the shot peening chamber 1 is connected with the ultrasonic vibration device 2 . The upper surface of the shot-peening chamber 1 can cooperate with the lower surface of the fan bl...

Abstract

The invention discloses an ultrasonic shot peening strengthening equipment, which comprises: an ultrasonic vibrating device, projectiles, and a shot peening chamber for containing the projectiles, wherein the shot peening chamber is a cylindrical structure, and the The vibration head of the ultrasonic vibration device is close to the lower port of the shot blasting chamber. When the ultrasonic shot peening strengthening equipment of the present invention is used for ultrasonic shot peening strengthening, fewer projectiles are used, the energy consumption is lower, and dust and noise pollution can be effectively reduced. Ultrasonic shot peening is used to strengthen the fan blade damping table, which overcomes the problem of projectile ejection and can effectively improve the efficiency of ultrasonic shot peening of the fan blade damping table.

Description

technical field [0001] The invention relates to the technical field of fan blade surface treatment equipment, in particular to ultrasonic shot peening equipment. Background technique [0002] In an aero-engine, the blade is the main component that generates power. In a turbofan engine, generally, a raised portion that is connected to each other is provided at a position where the height of the fan blade is appropriate, called a damping table, and its function is to form a ring between the blades. belt to increase blade rigidity and prevent fan blade flutter. As an important part of the fan blade, the surface quality of the damping table directly affects the fatigue life of the fan blade and the safety and reliability of the entire engine. In order to improve the fatigue strength of the damping table, in the process of manufacturing fan blades, the surface strengthening process is generally used for strengthening treatment. Among them, shot peening is the most commonly used...
