Automatic ultrasonic shot blasting device and method for processing metal sheet

Abstract

The invention discloses an automatic ultrasonic shot blasting device and method for processing a metal sheet. The automatic ultrasonic shot blasting device comprises an ultrasonic shot blasting gun, a shot blasting gun fixing mechanism, a movement mechanism, a frame stabilizing mechanism and a metal sheet fixing mechanism, wherein the ultrasonic shot blasting gun is used for carrying out the shot blasting of the to-be-processed metal sheet; the shot blasting gun fixing mechanism is used for fixing the ultrasonic shot blasting gun; the movement mechanism is arranged to be capable of moving in the X-axis direction or the Y-axis direction or the Z-axis direction; the shot blasting gun fixing mechanism is arranged on the movement mechanism; the movement mechanism is used for enabling the shot blasting gun fixing mechanism to move in the X-axis direction or the Y-axis direction or the Z-axis direction, and therefore the ultrasonic shot blasting gun can move in the X-axis direction or the Y-axis direction or the Z-axis direction; the frame stabilizing mechanism is used for supporting the movement mechanism; and the metal sheet fixing mechanism is used for fixing the to-be-processed metal sheet. The automatic ultrasonic shot blasting device can realize automatic shot blasting treatment on the metal sheet.

Description

technical field [0001] The invention relates to an automatic ultrasonic shot blasting device and method for processing thin metal plates. Background technique [0002] Needle-type ultrasonic shot peening surface strengthening treatment technology is also called ultrasonic shot peening technology. Its main working principle is: the transducer in the ultrasonic shot peening gun converts electrical energy into mechanical energy, drives the array to impact the needle vibration, and impacts the surface of the component. The surface introduces residual compressive stress. Ultrasonic shot peening is mainly suitable for forming, correcting, strengthening and prolonging the life of thin plates of different sizes. Ultrasonic shot peening is used for large thin-plate structures such as aircraft skins and rocket missile shells, which are difficult to form during production. Small thin sheet materials used for scientific experiments were also ultrasonically peened to study the effect o...

AI Technical Summary

Problems solved by technology

[0003] At present, manual hand-held methods are still used to carry out ultrasonic shot peening surface strengthening treatment on small metal sheets, which cannot be processed continuously and cannot realize the automation of the processing process.

During the ultrasonic shot peening process, there will be serious noise and metal shavings splashing, and the vibration of the ultrasonic shot peening gun may cause physical discomfort and affect the health of the operator

In addition, there are still the following disadvantages in the manual hand-held ultrasonic shot peening surface strengthening treatment: the impact needle of the shot peening gun array cannot guarantee the vertical impact on the material surface, the impact amplitude cannot be locked, the impact time of the shot peening area is not uniform, the speed of the shot peening and the movement path Not precisely controllable, etc.
