Abstract

The invention relates to a soft abrasive particle flow processing method loaded with ultrasonic excitation. A soft abrasive particle flow processing device comprises a constraint runner base and a constraint module. The inlet of a constraint runner is connected with an outlet of a hydraulic pump. The constraint module is provided with a vibrating part connected with an ultrasonic generator. The constraint module is provided with a vibrating sensor for monitoring a vibrating signal value. Pressure sensors are respectively arranged at inlet and outlet of the constraint runner. A flowmeter is arranged at the outlet. The processing method comprises the steps of: monitoring a vibrating signal, a pressure signal and a flow signal in real time, and inputting the signals collected to a flow control equation under a Cartesian coordinate system; controlling the flow state of the soft abrasive particle flow in real time by controlling the input speed of the pump and frequency of the ultrasonic generator so as to control the whole polishing process. The invention further provides a soft abrasive particle flow processing method. According to the soft abrasive particle flow processing method loaded with ultrasonic excitation and the device thereof provided by the invention, the turbulence intensity is increased, the processing efficiency is improved and the energy consumption is reduced, and the method and the device are suitable for processing complex workpieces and the processing dead angle is effectively eliminated.

Description

technical field [0001] The invention relates to the field of soft abrasive flow precision machining, in particular to a soft abrasive flow processing method and a device thereof. Background technique [0002] Nowadays, with the development of fast fashion in the manufacturing industry, people have higher and higher requirements for the precision of the surface of the parts. The precision machining of the free-form surface of the parts can be applied to new technologies such as airbag polishing. The structure of the parts processed now is complicated, and the structured surfaces such as grooves, grooves, hollows, prisms, pyramids, and narrow slits involved in mold manufacturing are increasing, but the research on the precision finishing technology of these surfaces is relatively weak. Liquid-solid two-phase soft abrasive flow processing is the application of soft abrasive flow to form turbulent flow on the structured surface of the workpiece to be processed, coupled with a co...
