Abstract
The utility model discloses a male and female wearable steel ball, and relates to the technical field of wearable steel balls. The male and female wearable steel ball comprises a mother hemisphere and a son hemisphere; the mother hemisphere is provided with a trapezoidal groove; a trapezoidal lug boss is arranged on the son hemisphere; the trapezoidal lug boss is matched with the trapezoidal groove; or the trapezoidal lug boss is arranged on the mother hemisphere; the trapezoidal groove is formed in the son hemisphere; the trapezoidal groove is matched with the trapezoidal lug boss. The male and female wearable steel ball has the beneficial effects that a high-chromium wearable steel ball and a low-chromium wearable steel ball are halved and blended into one wearable steel ball, so as to form the male and female wearable steel ball, so that the overall performance of the wearable steel ball is improved, and the application range of the wearable steel ball is wider. By adopting a secondary pouring mode, a half of wire-cut steel ball is filled into an overall steel ball, so that fracture and the dislocation phenomena of the male and female wearable steel ball obtained in a mechanical connection mode or a welding combination mode in the use procedure are avoided.
