The invention provides a multi-station cold extruding forming method of a sleeve barrel, comprising the following step: fracturing materials to form a cold extruding material part, and also comprising the following cold extruding processing steps after material fracturing: shaping and edging the end surface of the material part to be dug with a dug hexagonal hole; shortening a pole positioned at the rear of the material part, and forming a guide hole at the rear of the material part; digging a positioning hole on the end surface to be dug with the dug hexagonal hole; digging the hexagonal hole, and prolonging the material part; digging a middle circular hole of the sleeve barrel, and forming a guide hole on the bottom of the middle circular hole; backwards digging a square hole on the basis of the guide hole positioned on the bottom of the middle circular hole; forwards digging a square hole on the basis of the guide hole positioned on the end surface of the rear of the material part;and communicating the backwards dug square hole and the forwards dug square hole. The invention enables the sleeve barrel to be manufactured by the cold extruding method, has quick speed, high precision and production efficiency, few waste material and even no waste material, thereby greatly saving the original materials and reducing the production cost; and in addition, the cold extruding enhances the mechanical property of products and ensures the quality of the products, thus the products have more advantages on a utilization function.
