    采访:塔塔汽车公司,Dileep Naik

    2015-01-07T10:39:07Z

    汽车项目与生产工程总监谈论了有关商用车制造,公司在马哈拉斯特拉工厂制造商用车与动力系统的情况,以及国内生产工程能力等情AMS: 你们目前在宾布里生产什么汽车?Dileep Naik(DN):我们在这里生产商用车(CV)和乘用车。商用车包括轻型商用车(LCV)、中级商务车(ICV)和多用途汽车(MUV)。重型商用车和公交车是在另一个地方生产。在宾布里的乘用车包括斜背式和轿车款车型。 除此之外,我们在这里还有一个发动机部门,生产发动机和变速器;一个生产模具的生产工程部门;以及一个为冲压件、模制件和钻模制造模具的部门。AMS: 印度的经济增长已经放缓,并影响到汽车销售。这对宾布里的生产量有什么影响吗?DN:小汽车和商用车市场都受到经济停滞的影响。这就意味着要对小汽车和商用车进行20-30%的减产。但是,新政府已经承诺要实施一些积极的措施来促进经济,因此未来发展还是很乐观的。 AMS: 你们是如何调整生产运营,以适应目前的需求水平的?DN:设备利用是根据车段和车型范围决定的,但是我们的生产很灵活,能够应付这些需求方面的动荡。  AMS: 你们的LCV,MUV和皮卡车系列共性有多少,能公用多少平台呢?DN:这些车型的共性大约在85%左右,能公用装配线。还有,喷漆厂经过设计,也能够综合处理这些车型和平台。当然大型卡车就很难共享这些了,大小和重量上的差别是无法共享平台和组件的。 AMS: 有没有计划要在宾布里增加新的车型,或者扩建工厂?DN:到目前是没有,但是在发展过程中还会对生产战略进行修改。很显然,还需在市场恢复之后才能增加额外生产。 简介:Dileep Naik, 汽车企划与生产工程总监·Naik于1979年毕业与普纳工学院(COEP)机械工程系。·他于1981年加入塔塔汽车公司汽车企划部门·他的工作是负责BIW(白车身)策划执行活动,以及所有车辆和轮轴类型的TCF文件·Naik有2年的时间在韩国塔塔大宇商用车(TDCV)公司,担任新产品引进(NPI)部门的领导职务·他已经在塔塔汽车接手了4个绿地项目AMS: 这家工厂是什么时候建立的?DN:我想应该是从1977年开始生产的。 AMS: 关于CV生产自动化水平方面,你们有什么战略吗?DN:我们正在生产量和人力成本之间调节平衡。这是很重要的因素,但是对某些方面来说,目前自动化是最佳选择,比如喷漆车间。目前汽车车体修理厂的人力操作成分相对较高。很多事情还要看将来的产量。如果产量上来了,那么自动化的成本效益就更高。 AMS: 这里的经营有什么新的进展吗,比如与制造工程相关的什么?DN:我们为许多不同的客户制造模具,比如钻模、冲模、钣金等夹具,还有就是我们自己的生产作业。这里涵盖了从设计、开发到工具制造的所有过程。在如何做事上还是有一些开发的,但是这都是循序渐进的,并不是大的变化。 AMS: 你们开发这个厂内生产工程的原因是什么?DN:这样我们就可以将产品很快地投放到市场中。在这里开发任何新的工具或做的任何改变都可以节省很多时间,而这对我们是非常重要的。 AMS: 在塔塔汽车制造生产中,达到多少标准化呢?DN:在小汽车和商用车生产方面达成很好的协同增效。参观宾布里塔塔工厂除了生产商用车,乘用车和动力系统之外,马哈拉斯特拉的宾布里塔塔工厂还是生产工程部门的老家,这为汽车的快速设计、开发制造提供方便 宾布里塔塔工厂纵向一体化水平很好,生产工程部门的构成也是如此。这里就是开发和制造汽车生产工具的地方,囊括从夹具及固定装置到板材冲压的所有一切。这里生产公司66%的钣金模具,真是令人印象深刻;设备包括70个CAD站和14个大型CNC。这里每年制造大约290个模具。这些模具和夹具还为公司以外的客户生产,比如福特、丰田、本田和捷豹路虎。 制造完美组合设计和制造这些模具需要结合重型工程、高科技、电脑控制机械加工,以及仿真设计系统。对于模具来说,大块的高强钢要首先锻造称两块完全吻合的平面;虽然这些大型工具的重量达到好几吨,但是在整个阶段都需要保证高度的精确性,才能生产精确耐用的模型。制模车间采用3轴和5轴加工中心,前者用于执行最初简单一些的切削操作,而后者用于执行复杂的任务。一旦平面完成,板块就可以精确地分为两半。CAD系统就为加工中心编程,生产想要的车身板件外形。 这个过程需要在加工中心进行大量的转移,最后要进行3次周转才最终完工。这个过程非常重要,因为模具外形要一点瑕疵都没有才能制造A-级板材。 然后模具要送到Shuler压力机那里进行性能检测。在达成想要的冲压质量和精确度之前,要经过大量的调整阶段。在这个过程中,有个叫做“定位”的操作过程。这个过程要对模具的两半进行精密调整,使用手动工具。只有这样,模具才能反复制造出完美的板材。 夹具的生产要根据应用,综合铸造、机械加工和装配等工艺。为了铸造更加复杂的形状,苯乙烯模具应运而生,并送到一个专门的铸造公司。

    阿拉巴马: 本田的安乐窝

    2014-11-18T11:05:42Z

    该原始设备制造商在Lincon的工厂,已经以更高的自动化升级了动力系统和冲压生产线 阿拉巴马的本田制造厂(HMA),被选中制造Acura MDX车型,这是工厂里技术性最高的产品制造。HMA工厂被列入轻型车制造厂的行列,主要制造三种车型:Odyssey,Pilot和MDX。 工厂里一直为国内巨大的皮卡车市场生产Ridgeline汽车,但是为了准备推出全新皮卡车,所有生产都将停止。 工厂占地1,300英亩,厂房设施占地超过300万平方英尺,拥有4,000名员工。除了汽车生产,工厂还拥有400,000平方英尺的动力系统生产车间,每年共生产340,000部汽车和发动机。工厂最近引进自动化水平更高的程序,极大推动了V6发动机的生产。 HMA公司总裁Jeff Tomlo说,“目前的发动机生产将搬到新工厂的一个生产线上,在那里可以根据要求,比如车型变体,在第一生产新或第二生产线上进行生产。现在发动机生产的自动化水平在32-35%之间,所以算是人力密集型操作。新设施的自动化水平达到65-70%;几乎是原来的2倍。这将成为本田工厂里自动化水平最高的发动机装配线之一。” 他继续说道:“自动化可以实现进一步的质量检验和核查,而且由于发动机变得越来越复杂,而且变型也越来越多,这个生产线的增加能使我们灵活制造不同类型的发动机,而不需要做很多修改。” 工程技术实力Lincoln的制造车间包括:一个适用钢和铝的冲裁生产线;冲压;焊接;喷漆;注塑模具;铸铝;铝和亚铁加工;汽车组件和装配;发动机装配;车辆实验;和质量保证。 这个生产线反映了本田公司的垂直一体化制造工艺。虽然公司已经与外部供应商之间建立了强大的长期合作关系,但是公司将一直利用其发达的工程技术实力;现场铸铝和注塑模具(有3个模具用于保险杠和仪表板生产)就是个好例子。 本田想要在厂内保留复杂的装配工艺的意愿已经非常明显。仪表盘 — 通常是由主要供应商装配,然后运送到其他原始设备制造商的生产线上 — 是在本田Lincoln工厂装配而成,每件只需23分钟的程序。 伺服控制冲压操作是在以液压操作的两个AIDA冲压线上进行,现在又有一个额外新的伺服冲床作补充,这能在强钢成型时提供更强的控制。压力机为以4个阶段锻造class-A面板,具有自动化处理与堆叠操作的特点;冲模转换能在7至8分钟内完成。然后由转包商完成较小的子结构冲压工作。 汽车车体修理厂实现了高度自动化(80-90%),有200个机器人实行操作和焊接,每天能生产1,500个单位。在这里人工操作相对少的工作就是,将车门搬到一个旋转站,然后(由机器人)完成焊接。 与许多原始设备制造商相同,本田在Lincoln实行准时制零部件送递程序,在现场保留4小时工作量的零部件。整个车辆生产量都在送递之前进行跟踪监测(这是质量控制程序的一部分)。目前,HMA制造车辆中大约有10%是预定出口的。 HMA的大事年表 1999 — 宣布了斥资4亿美元在阿拉巴马建新厂的计划 2000 — Lincoln工厂破土动工 2001 — 第一辆Odyssey微型客车走下生产线 2002 — 宣布斥资4.2亿美元进行扩大建设;添加第3条生产线 2004 — 在Lincoln工厂的第2条生产线上进行试选车型的量产 2005 — 工厂创下生产达到500,000辆的里程碑 2006 — Lincoln工厂生产出第1百万辆汽车 2008 — Ridgeline的生产转到HMA;第2生产线上增加了Accord ...
