    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 Bielefeld工厂经理Lutz Huxholl称,冲压机目前能够成功制造“主要底盘”零部件,提供给高前杠用户。这些零部件包括“弹簧连杆和下控制臂”。 对安装规模而言,Huxholl称这与立即解决制造任务是两回事。Gestamp还认为,这个技术在未来很有前途,并且能够加强市场公信力。他说,“经过这次投资,Gestamp Bielefeld工厂正在向未来大踏步前进,同时还能保证目前的竞争力。这个伺服冲压机为我们提供新的制造选项。对汽车供应商来说,配有现代化生产设别非常重要。而且,这种伺服多工位压力机能够提供独一无二的卖点。” 改进能源管理 但伺服冲压技术对大西洋另一侧的行业却造成了巨大的打击。这里的主要技术供应商是Komatsu North America。产品经理George Schreck认为,精确控制滑板移动时该技术的关键。他还说,与飞轮压力机相比,这能够代表“能源管理”的特点优势。飞轮压力机的局限性在于,它在快速旋转的过程中,只能将能量转移到画板上,则就要求滑板的速度也要很快。但该技术从本质上具有更高的能源效率。 在这一点上Schreck认为,Komatsu与第三方机构合作进行测试的结果显示,“在物理工作中,伺服压力机要比飞轮压力机的能源效率要高出30-40%。”他说,与液压机相比的话,能源效率差异会更加明显。 这并不是说液压机和飞轮压力机在很和情况下都不适合使用。Schreck认为,器拿着具有“深拉”能力,而后者可以在高单速滑板移动中更有利,而且不需要先进的控制技术。尽管如此,Schreck肯定地说,市场对伺服冲压技术的青睐越来越大。在Komatsu North ...
