在生产大跃进中,我厂职工破除了迷信,充分发挥了敢想敢作的精神,大胆地采用水泥和岩石制成冲模来冲压46型汽车壳体,已试制成功。这说明水泥、岩石不但能制造各种机器,且能承受一定程度的冲击力。如我厂制造的46型吉普车壳体(1.6公厘的钢板)原来使用手工敲打,现改用水泥和岩石冲模在200吨冲床上冲压,比手工操作提高20多倍。
In the process of the Great Leap Forward, our factory employees broke away from superstition and gave full play to their courage and daring spirit. They boldly used the cement and rock to make stamping 46-type automobile shell, which has been trial-produced successfully. This shows that cement, rock can not only create a variety of machines, and can withstand a certain degree of impact. For example, the 46 jeep shell (1.6mm steel plate) manufactured by our factory was originally hand-beat. Now it is punched with 200-ton punching machine by using cement and rock die, which is 20 times more than manual operation.
