Abstract
本发明的主题是一种用于将陶瓷功能体(1)插入管形的金属外壳(3)中的方法。在对功能体(1)测量之后用一种轴承垫(2)缠绕这个功能体,并且插入到所述外壳(3)中。然后对整个外壳(3)进行加热。然后在这种状态中外壳(3)减小到尺寸(D’),该尺寸在热状态中由陶瓷功能体(1)的实际尺寸(d)加上所力求的间隙尺寸得出。在冷却时外壳(3)收缩以及功能体(1)和轴承垫(2)准确地位于外壳(3)中。
Description
技术领域
本发明涉及一种按照权利要求1的前序部分所述的将陶瓷功能体插入管形金属外壳的方法。此外,本发明还涉及一种如此制成的装置。
背景技术
陶瓷功能体在使用内燃机的汽车的排气装置中用作催化器以及用作柴油碳黑颗粒过滤器。陶瓷功能体设置在一个金属外壳中,该金属外壳具有一个板状外罩、一个输入锥体和一个输出锥体。为了能平衡金属和陶瓷的不同的热膨胀系数,用一种合适的轴承垫缠绕陶瓷体,并且将其插入到该壳体中。当环境温度例如下降到-30℃,或者当排气温度最高达900℃,为了将陶瓷功能体的支承保持在金属外壳中,金属外壳、轴承垫和陶瓷功能体的尺寸必须彼此准确地协调。
遗憾的是由于制造方法的原因陶瓷功能体具有很大的直径公差。因此需要对每个陶瓷体进行测量,为的是能够确定合适的金属外壳。这就相当费事。
曾有人建议使用具有超尺寸的金属外壳,并且在用轴承垫缠绕的陶瓷体插入后对金属外壳进行校准。US 5 055 274公开了一种这样的校准方法,其中使用具有校准钳的校准工具。EP 0 768 451 A公开了一种方法,在该方法中借助压紧辊校准金属外壳。
因为外壳的金属板具有在校准之后,也就是在减小直径以后又重新回弹的特性,所以必须先将直径减小得多一点。在此就存在损害陶瓷功能体的危险。因为外壳已经封闭,这种损伤不再能看得出来。此外,由于短时间的过挤压使轴承垫的功能受到很大的损害。因此在上述两文献中所述随后校准金属外壳的方法无法付诸实施。
发明内容
本发明的任务是提供一种方法,借助该方法可无损坏陶瓷功能体或者轴承垫危险地进行外壳的随后校准。
该任务通过具有权利要求1特征的方法得以完成。
由于在减小直径前对外壳加热得到两个优点:一方面是花费比较小的力可使已加热并因此变软的板材变形,并且仅具有最小的反弹倾向。另一方面只需将外壳的直径减小到在最高加热运行时外壳所具有的最大直径值,通过这一措施对轴承垫和陶瓷体仅施加最小的力,从而就排除了损坏。只要将外壳冷却到环境温度,陶瓷功能体就准确地位于外壳之中。
优选地借助感应加热对外壳进行加热。替代地或者补充地也可借助火焰加热。
优选地将外壳加热到赤热,直到白热,相当于最高900℃的温度。
被加热的外壳可如已公开的那样借助校准钳,也可借助压紧辊进行校准。
此外,用于再处理内燃机废气的按照本发明方法制造的的装置也是本发明的主题。在这种情况中所涉及的是具有陶瓷功能体的催化器或者碳黑颗粒过滤器。为了使陶瓷的机械载荷保持尽可能地小,在校准过程中将外壳加热到900℃并且校准到由功能体的直径和轴承垫的厚度计算出来的尺寸。
附图说明
借助附图以实施例的形式对本发明进行更详细的说明。这些图分别完全示意地示出。
图1:一个用轴承垫缠绕的陶瓷功能体插入到一个管形的金属外壳中,
图2:对外壳加热,
图3:借助校准钳将已加热的外壳校准到与陶瓷功能体相对应的直径尺寸,
图4:借助压紧辊校准。
具体实施方式
借助图1到图4完全示意地对根据本发明的方法过程进行说明。
首先测量陶瓷功能体1,例如催化器或者柴油碳黑颗粒过滤器。在此特别是测出直径d。当功能体为椭圆形时测量多个直径。
然后用轴承垫2缠绕陶瓷功能体1。
在图1中借助漏斗11将已缠绕的功能体1、2插入到一个管形的外壳3中。该外壳3有明显的过量尺寸D。这样轴承垫2实际不被挤压。它没有经受剪切力。陶瓷体1和轴承垫2可以在外壳3中精确地定位。轴承垫2保持它的位置,陶瓷体1不会歪斜。
在缠绕的陶瓷体1、2插入之后,如图2所示将外壳3在约五秒钟内加热到赤热,直到白热。在这种情况中优选地采用一种感应回线5.2。补充地或者替代地也可借助火焰5.1加热。外壳3的端部4不必加热。
图3示出如何借助校准钳6.1、6.2对已加热的外壳3进行校准的。在这种情况中,按照在图1中将处于热状态中壳体的直径D’校准到所测得的直径尺寸d加上收缩量。
图4示出如何借助一个压紧辊7将已加热的外壳3校准到尺寸D’。
在随后冷却中外壳3收缩到所力求的最终尺寸,其中,轴承垫2以最保护的方式压缩到所希望的数值。在此,无论是陶瓷体1还是轴承垫2都不会受损。陶瓷功能体1在所有运行状态中都将它的位置保持在外壳3的内部。
