- 伺服的曲线发展之路
被称为汽车业最大的伺服冲压机安装之后用于金属成形，这是冲压技术目前最大的进步 伺服冲压技术一直以来都在消耗汽车金属成型应用。其中的原因对汽车部门的需求来说并不算特殊，但是这番印了该技术的有点可疑应用到制造流程中。最关键的就是利用伺服冲压技术的灵活性控制；滑动可疑直接通过点击完成，并在单一操作中就完成变更 — 加速、减速或者停止 — 这根据需求来动。这种结果就是加强了零部件成型准确率，同时不会降低材料质量，也不用考虑目标零部件的几何结构。 该技术拥有两个冲压技术对手。他们是非伺服机械压力机，这种技术将电机能量通过复杂的离合器、齿轮、系统传递给刀片。另一个是飞轮和液压机在，电机会驱动一个液压泵，之后又反过来驱动活塞缸套组驱动刀片。这两种技术仍然在使用，但是没有一个能够媲美伺服冲压机的灵活性，因为这两种技术中，刀片运动在振幅和速度上都是固定的。 此外，伺服冲压技术在汽车制造部门的优点刚刚又取得了突破性的进展 — 准确地说是在最近委任所谓的最大的机械使用。该机械目前在德国Bielefeld工厂运行，这是西班牙巩固组件制造商Gestamp Automoción旗下工厂。正确的说，该机械从设计到安装，都拥有西班牙原厂产品，由来自Bielefeld和Logroño（这里是日本-西班牙设备供应商Nidec ARISA的办公室所在地）组成的团队联合完成。 Gestamp Bielefeld工厂里的伺服冲压机长37米，重1,350吨 Bielefeld的大家伙光是安装尺寸（去年12月从德国运来）就能看到它的不同。设备中体长度37米，宽20日，高10米，地下还有6米长。总重量为1,350吨，额定功率达到9MW转矩和7MW蓄能，可以通过一个补充发动机完成，所有这些特性，足以使机械在模面产生45,000KN的压力。 整个系统配有一个单一压力机，上面有两个车厢和三个支柱，可以瞄准模具的偏心载荷。该机械通过一种格式化拆包机给料，经过多个装在站，目的是为机械操作员提供人体工学效率。同时，有一个传送带系统，通过一个石油编程还贷润滑器运输材料，保证每个操作中最佳油使用。这种模具更换系统，包括拆垛机的更换，都是全自动的。 线下编程可以通过Nidec ARISA自主产品Optiservo软件运行，这个是为了考虑公司冲压机的开口曲线而特别编写的，这可以让操作员制造很多种曲线。特别要注意的是，该软件能让生产工程师模拟并优化曲线，而且不需要停止生产，同时降低启动时间，避免碰撞。 “汽车业的规格，以及不间断的快速发展需要精确而灵活的机械，这使不同材料和模具可以混合工作，提高了速度，降低了能耗” - Roberto Gonzalo, Nidec ARISA 这些细节都得到了Nidec ARISA公司项目经理Roberto Gonzalo的证实。他还说，Bielefeld安装目前这个伺服冲压机是公司目前以来最大的，他还说，“这也是串联伺服冲压机”。尽管如此，这个记录可能要马上被打破，因为Gonzalo解释说，“我们还要使用其他类似尺寸的机械”。 新的境界据Gonzalo称，在Bielefeld设计、制造并安装新的伺服冲压机项目面临一些根本性的问题，比如如何实现绩效目标。他说，“在设计过程中，我们已经解决了高抗张强度新材料的印刷工艺问题，尤其是面对第一成型站和后面之间的压力差异问题，因为这会造成多工位压力机的变形。“ 他们面临很多种方案，比如在多工位压力机之前使用个别压力机。但Gonzalo认为，这种方法不够简便。他说，“变形过程通常都是深拉成型的，需要高压。”她还解释说，这可能会在冲压过程中损坏模具负载的对称性。但是，这种系统的主要缺点在于，他会总体上降低绩效，因为它需要将零部件从一个冲压机移动到另一个冲压机上。 另一个方案就是制造一种单独的不对称压力机，这种压力机可以承受使用过程中产生的压力造成的变形，并有压力机的不对称结构进行补充。但是，这种刚发也存在问题。Gonzalo说，“这种方法在模具需要的尺寸不变的情况下是可行的，但是单一托班冲压无法制造。此外，这种冲压机会在缓慢负载模具分配的情况下造成不对称变形。” 因此Gonzalo认为，所选的技术方案需要一种单一冲压机上带有两个拖板，三个垂直的能够瞄准偏心载荷的模具，并且可以操作各种模具尺寸的工作。这种高要求还复杂了，“压力机应该是伺服驱动”才能实现一定的质量水平。它而得传递过程还能实现较高生产率。他说，“材料的高抗张强度需要非常准确的成型速度，才能制造高质量零部件。只有精确速度控制的伺服冲压机才能实现这个要求。”此外，在建造过程中还有一个困难，就是制造安装装量超过200吨的组件精确率要低于0.1mm。 要让客户满意Gonzalo补充说，这种性能等级要求尽管不是汽车业唯一，但确实目前非常典型的。他说，“这种规格，以及汽车业的快读不断的发展都要求精确而灵活的机械，能够完成不同材料和模具的工作，提高速度，降低能耗。只有伺服冲压机能够满足这些要求。” 同时，冲压机用户表示，新的机械要满足他们的预期。据Gestamp ...
