拉深工艺的原理并不新奇,已用于生产罐类制件很多年了。各种应用系统也有稳定的发展。但是开发液压机后才为工程师们展示了一个全新的领域。特别是应用计算机程序控制这些压力机,使机床的调试快速而精确。虽然很多公司仍采用旧式机械压力机拉深各种罐件、圆筒件等,但在两次成形之间常需回火。无疑越来越多的由计算机控制的液压机将投入使用。这些压力机可大大降低生产成本。它们将完全主宰拉深压力机的未来市场。 The principle of deep drawing is not new and has been used to produce cans for many years. Various application systems also have steady development. But developing the hydraulic press showed engineers a whole new world. In particular, the use of computer programs to control these presses, the machine debugging fast and accurate. Although many companies still use the old mechanical presses deep drawing of various pieces of cans, cylinder parts, but often between the two forming tempering. No doubt more and more computer-controlled hydraulic presses will be put into use. These presses can greatly reduce production costs. They will completely dominate the future market of deep drawing presses.
