More Information
Summary:The utility model discloses a novel die for machining a magnetic material. The novel die comprises a female die and a pressure head, wherein the upper surface and the lower surface of the pressure head are radian surfaces which project outwards; the heights of the middles of the upper and lower surfaces are 1.2-1.5 millimeters greater than the heights of the two ends; a platform of 20-30 millimeters is arranged between the upper and lower surfaces; a groove part which adapts to the pressure head in shape is formed in the middle of the female die; the contraction ratio of a magnetic material inside the groove is 0.67-0.68. The novel die has the characteristics of simple structure, high surface flatness, saving of materials, saving of time and labor force, high production efficiency, and the like.
