Abstract

The invention relates to a pulsed abrasive flow polishing device and method, and provides a pulse generating device which can generate four different pressure forms. Different tooth forms and tooth spacings are designed, and different mechanical structures are used for generating stable sinusoidal pressure wave, triangular pressure wave, trapezoidal pressure wave and standard sine-cosine pressurewave, so that the effect of increasing the fluid turbulent kinetic energy is achieved, the uniform machining effect is achieved, additionally, different pressure forms are selected according to different material hardness and high-temperature oxidation effects during machining, the characteristics of different kinds of pressure wave are exerted, and the machining effects of high efficiency and economy are achieved.

Description

technical field [0001] The invention belongs to the field of abrasive flow processing technology and ultra-precision processing, and specifically designs a pulsed abrasive flow polishing device and method. The abrasive flow processing technology is widely used in the fields of automobiles, aerospace and biomedicine. Pulsed abrasive flow belongs to the field of ultra-precision technology processing. Background technique [0002] Abrasive flow polishing is the removal of material produced by friction between abrasive particles near the wall and the wall surface of the workpiece under the action of pressure. Therefore, when only considering the collision between particles and the wall surface and not considering the surface oxidation caused by high temperature, The greater the particle concentration, the more the number of particles, the better the processing effect, and the laminar flow field will make the surface of the workpiece show a certain regularity, which is not allowe...
