Abstract

The invention provides a stirring head for processing modification of a stirring friction surface of a surface layer of a metal material. The stirring head mainly comprises a lower shaft shoulder (1)and an upper shaft shoulder (2), wherein the lower shaft shoulder (1) and the upper shaft shoulder (2) are connected. The stirring head is characterized in that a cavity is formed inside the lower shaft shoulder (1), and small circular holes (8) are formed in the bottom of the lower shaft shoulder (1). The upper shaft shoulder (2) and a clamping handle (3) are integrated, a sliding hole (4) is formed inside the upper shaft shoulder (2), and a control component (6), a hydraulic device (5) and steel balls (7) are installed on the top of the sliding hole (4). The hole diameter of each small circular hole (8) is smaller than the diameter of the corresponding steel ball (7). By the adoption of the stirring head, the surface modification quality of the metal surface layer can be substantially improved, the modification efficiency is improved, and the modification cost is saved.

Description

technical field [0001] The invention relates to a surface modification technology, in particular to a technology for modifying the surface of metal materials by friction stirring, in particular to a stirring head for surface modification of metal materials by friction stirring. Background technique [0002] Metal materials will be more or less affected by poor surface properties during use. In order to improve the use performance of the metal surface layer, the present invention avoids the characteristics of traditional chemical modification and pollutes the environment, and adopts the method of green processing, that is, friction stir Surface modification technology is used to modify the metal surface layer. The most critical thing for friction stir surface modification is the stirring head. The traditionally manufactured stirring head has poor modification effect due to reasons such as structure and material. The present invention is based on this reason. Develop a compreh...
