Problems solved by technology

Therefore, there may be a problem of inconsistent shot peening construction
[0007] In addition, especially when the construction part of the concave part is located on one side of the direction of gravity, since the distance between the surface of the vibrator and the surface of the construction part varies with the position of the surface of the construction part, the distance between the construction part The projectile material rebounded from the surface cannot reach the vibrator, and there may be constructions that cannot continue the shot blasting process

Embodiment Construction

[0028] Hereinafter, the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to the best form (henceforth an Example) for carrying out this invention. In addition, the constituent elements in the following examples include elements that can be easily conceived by those skilled in the art, are substantially the same, and are within the so-called equivalent range.

[0029] The present invention is suitable for shot blasting of concave or convex shapes. In addition, in this invention, the construction part of a shot blast process is not limited to a welded part. In addition, the present invention is generally applicable to, for example, the inside and outside of the inlet and outlet of steam generators used in power generation equipment, fluid piping, pressure vessels, and other parts that require shot blasting, and the applicable objects of the present invention are not particularly limited.

Abstract

A shot peening device (1) is equipped with a containment vessel (2) that stores shot material (B) used in shot peening, and performs shot peening of a worksite surface (UP) by the containment vessel (2) moving to the shot peening worksite (U). The shot peening device (1) is equipped with an oscillator (3). An oscillation means (4) that imparts kinetic energy to the shot material (B) in the container interior (2I) is mounted on the oscillator (3). The external shape of the oscillator (3) is formed into a shape matched to the shape of the worksite surface (UP) of the worksite (U).

Description

technical field [0001] The present invention relates to shot peening. Background technique [0002] The so-called shot peening is a kind of cold working. By making the iron or non-ferrous metal ball projectile material hit the metal surface at high speed, the metal surface generates compressive stress, and the fatigue strength against the load is repeatedly improved. In a pressure vessel of a chemical plant, an atomic furnace vessel, etc., for example, in order to improve the fatigue strength of the welded joint, the welded portion is subjected to shot blasting. Patent Document 1 discloses an ultrasonic shot blasting processing apparatus that performs shot blasting on the J-welded portion of the lower surface of the nuclear reactor vessel cover and the tube base, and the surface adjacent to the J-welded portion. In addition, Patent Document 2 discloses a tip tool guide device that is carried into a water chamber of a steam generator of a nuclear power plant and guides a tip...
