| description | The invention discloses a nose cone body of a drill chuck, which uses a steel plate as a raw material to replace a solid steel bar for production. A jacket and a liner of a hollow cone are made of steel plates; the front end of the liner is fixed in the jacket, while the tail end extends out of the jacket; the liner is a hollow cavity; a snap ring is embedded between the inner side of the bottom of the jacket and the outer wall of the liner; and plastics and other filler are filled in a clearance formed between the inner wall of the jacket and the outer wall of the liner. Compared with the prior art, the nose cone reduces cost of raw materials of a unit product by 65 to 70 percent, and is only about 25 percent of the prior equipment investment with the same output, has simple operation andremarkably reduces manual manufacturing cost. Furthermore, the stability of machining accuracy of a stamping part is much stronger than that of a machining part; therefore, the nose cone can effectively improve the product q |
