Embodiment Construction

[0030] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] as attached figure 1 As shown in -6, the multi-needle impact head for the ultrasonic impact gun of the present invention includes an impact needle 1, an impact needle cover plate 2, and a horn end face 3. The end of the end surface of the horn is directly connected with the thread of the horn, and the end surface is provided with an impact needle, and the impact needle passes through the pinhole arranged on the impact needle cover plate, and the impact needle cover plate and the ultrasonic impact gun The gun body is fixedly connected. A moderate movable gap is reserved between the impact needle and the end face of the horn to ensure the normal vibration of the impact needle. The assembled multi-needle impact head is placed on the front end of the ultrasonic impact gun, and the workpiece to be treated...

Abstract

The invention discloses a multi-needle type impacting head for an ultrasonic impacting gun and a design method of the impacting head. The multi-needle type impacting head is composed of an amplitude-changing rod end surface, an impacting needle cover plate and impacting needles, wherein hole arrays in rows are filled in effective regions of the amplitude-changing rod end surface and an impacting needle cover. The multi-needle type impacting head and the design method thereof provided by the invention have the advantages that by virtue of the multiple impacting needles, compared with an existing impacting head, the work efficiency is improved by 300%-400%, the impact strength is improved by about 5%, and the problems that a welding structure cracks due to stress corrosion, is unstable and deforms, the fatigue service life of the welding structure is shortened and the like are effectively alleviated.

Description

[0001] This application is a divisional application of the parent application "a multi-needle impact head for an ultrasonic impact gun and its design method". The application number of the parent application is 2013102016550, and the filing date is May 27, 2013. technical field [0002] The invention relates to the technical field of metal surface nanotechnology, more specifically, to a multi-needle impact head for an ultrasonic impact (shot peening) gun and a design method thereof, which can be widely used in stress corrosion resistance, deformation correction, and residual stress elimination , metal surface nanotechnology and other fields. Background technique [0003] In the process of metal processing, metal welding is a commonly used processing method in the processing process. After the metal materials are welded according to the shape and size, due to the stress concentration of the weld toe and the residual tensile stress and other factors, the fatigue performance of ...
