The invention provides a piston for a breaking hammer and a manufacturing method thereof, and belongs to the technical field of breaking hammers. The problem that an existing piston cannot simultaneously meet the hardness and the anti-friction performance is solved. According to the piston for the breaking hammer and the manufacturing method thereof, the piston comprises a piston main body, wherein the outer peripheral surface of the piston main body is provided with an annular positioning boss, wear-resistant sleeves are arranged at the positions, on the front side or/and the rear side of thepositioning boss, of the piston main body in a sleeving mode, the wear-resistant sleeves are positioned on the piston main body, the outer diameter of the wear-resistant sleeves is larger than the outer diameter of the positioning boss, and one end surface of each wear-resistant sleeve abuts against one end surface of the positioning boss. According to the structure, the anti-loosening performance of a nut is remarkably improved. When the outer peripheral surfaces of the wear-resistant sleeves in the structure rub with the inner wall of a cylinder body of the breaking hammer, the outer peripheral surfaces of the wear-resistant sleeves are not likely to wear, and then it is ensured that the piston cannot be broken in the process of striking a drill rod and the boss also has very good friction resistance, so that the piston is not likely to wear and tear, and the service life of the piston is prolonged.
本发明提供了一种破碎锤用活塞及其制造方法，属于破碎锤技术领域。它解决了现有的活塞无法同时满足硬度和抗摩擦性能的问题。本破碎锤用活塞及其制造方法，包括活塞主体，所述活塞主体的外周面上具有均呈环状的定位凸台，所述活塞主体上位于定位凸台的前侧或/和后侧套设有耐磨套，所述耐磨套定位在活塞主体上，所述耐磨套的外径大于定位凸台的外径，所述耐磨套的一端面与定位凸台的一端面相抵靠。本结构显著提高了螺帽的防松性能。本结构耐磨套的外周面与破碎锤缸体的内壁发生摩擦时，耐磨套的外周面不易磨损，进而保证活塞在打击钎杆的过程中不发生破裂的同时凸台又具备非常好的抗摩擦性能，使得本活塞不易磨损和拉伤，延长了活塞的使用寿命。
