Abstract
The utility model discloses a reshaping mechanism installed on a round work piece of a press machine. The reshaping mechanism comprises a concave die component and a convex die component. The concave die component comprises a base seat and an outer sleeve fixed on the base seat. An inverted cone-shaped axial-direction through hole is formed in the middle of the outer sleeve and is matched with an inner sleeve, wherein the outer surface of the inner sleeve is in an inverted cone shape. A cylindrical axial-direction through hole is formed in the middle of the inner sleeve. A stripper plate is arranged on the lower portion of the axial-direction through hole in the middle of the inner sleeve. The inner sleeve is divided into four equal members along the axial direction in a cutting mode. A plurality of corresponding holes are formed among the side end faces of the equal members. Compression springs are arranged among the corresponding holes. The convex component comprises a fixing sleeve fixed with a sliding block of the press machine. A pushing rod capable of moving vertically is arranged in the middle of the fixing sleeve. A pressing plate is fixed at the lower end of the pushing rod.
