Abstract

The invention discloses an ultrasonic surface cleaning process for a forged workpiece. The process flow is as follows: feeding; entering an ultrasonic coarse cleaning tank; draining; spraying and rinsing under a high pressure; draining; entering an ultrasonic rinsing tank; wind shearing; cold air drying; and discharging. Technological parameters in the coarse cleaning tank and the rinsing tank are as follows: the concentration of an acidic cleaner is 3%-15% (pH=4-5.5), and the concentration of an alkaline cleaner is 3%-15% (pH=8-11); ultrasonic cleaning is performed at the temperature of 35-70 DEG C for 5-20 minutes under the conditions of ultrasonic power of 20-60kW and ultrasonic frequency of 20-45kHz; and ultrasonic rinsing is performed at the temperature of 25-45 DEG C for 5-15 minutes under the conditions of ultrasonic power of 20-60kW and ultrasonic frequency of 20-45kHz.

Description

technical field [0001] The invention relates to a cleaning process, in particular to an ultrasonic cleaning process for the surface of a forged workpiece. Background technique [0002] Oil-based graphite lubricant is used in the forging process. The lubricant is mainly composed of lubricating oil and graphite. Ordinary cleaning and grinding processes cannot completely remove the graphite lubricant, which affects product quality. Contents of the invention [0003] The object of the present invention is to provide an ultrasonic cleaning process for the surface of a forged workpiece that can be adapted to a large-scale assembly line. The surface ultrasonic cleaning process uses the physical action of ultrasonic waves and chemical cleaning agents to clean the high-temperature graphite lubricant and oxide layer on the surface of the workpiece. [0004] The flow of an ultrasonic cleaning process for the surface of a forged workpiece in the present invention is as follows: on-li...
