Abstract: |
Combined the actual production, this paper inturduces the life tests of mould with different materials, methods and hardness under the impact of the pulsed electromagnetic force. It analyses the factors of influencing the life of mould which used in the spring bulging, and put forward the solutions to improve the mould life. The actual results show that, under the action of the pulsed electromagnetic force, it is benefit for improving the mould life with reducing the hardness of the mould and increasing the toughness of anti-impact. |
