一、现状船厂生产设备自动化已有了一定的发展,但钢材的弯曲加工,仍然是较为薄弱的一环。究其原因,主要是这四点: (1)被加工的材料材质不均; (2)卸载时回弹规律较难掌握; (3)肋骨冷弯时前段与后段之间有塑性区重迭的影响; (4)数控装置的价格较贵,而生产对它的需要并不迫切。但是,随着造船工业的发展,钢材弯曲加工的自动化问题,必然会引起各方面的重视。在 First, the status quo Shipyard production automation equipment has been a certain degree of development, but the bending of steel processing, is still a weaker link. The reason is mainly the following four points: (1) the material being processed is of an uneven material; (2) the springback rule is unmanageable during unloading; (3) the plastic zone weight Diego effect; (4) numerical control device is more expensive, but the production of its needs is not urgent. However, with the development of the shipbuilding industry, the automation of steel bending processing will inevitably attract all aspects of attention. in
