Abstract

洗涤滚筒的流水孔被冲拉成U形或截锥状。为仔细处理高级织物，孔边(6)的锐利的边棱尽可能没有损坏性，在冲孔后将孔边压平。

Description

一种用于洗衣机的洗涤滚筒及其制造方法
本发明涉及一种用于洗衣机的洗涤滚筒，其中洗涤滚筒的板壁上有许多用于流通象水或空气等处理介质的小孔，其周围被拉成从洗涤滚筒外侧看为U形(tulpenfarig)或截锥状，以及用于生产这种洗涤滚筒的工具，其中包括一个被引导的冲头和一个开口的，安装在装入的板壁下面的支承支架。
DE 1 756 317U和DE 6606 902U曾公布了这类的洗涤滚筒。在DE 1 756 317U给出的洗涤滚筒生产工艺中，在冲制出U形之前必须先将每一个流水孔冲制出来。显而易见(DE 1756 317U，图1和图2)，孔边是倾斜于滚筒外壳的法线的。
在专利DE 66 06 902U中，理想地表示出了一种洗涤机械洗涤滚筒的流水孔。这类的流水孔甚至现在还在经常地按图1的方式生产，其中冲每一个流水孔时，在冲压工具2中的洗涤滚筒板壁1首先通过冲头3的向下运动被压低至支架4的位置，然后才冲压出切孔面5。
但在冲头3向下运动的剪切过程中，产生了一个倾斜于洗涤滚筒板壁1的U形切面，通过该切面就在孔边缘的下边6产生了锐利的边棱，这一在滚筒外边的锐利边棱同时造成了两方面的危险：一是下边6由此边棱变得如此地锋利，由滚筒内侧工作的洗衣机在使用者用手转动滚筒时割破指尖部位；另一个是洗涤物在滚筒加速旋转时被摔出流水孔，从而某些纤维可能挂在边棱上，当滚筒减速洗涤物回到滚筒中时，这些纤维就可能被割断。
不仅原则上这样简单的生产工艺应该保留，本发明的任务还在于，通过按图1所示简单的制造工艺生产开始时所提到的一种洗涤滚筒，而最大程度消除手指尖被割破；或织物纤维挂在流水孔外边而被割断的危险。
根据本发明，这一任务将通过形成平坦的孔边来完成。在平坦成形区，冲压后的孔边将被置到支架上，在孔边回拉时，已经成形的边棱拉到反向支架上并进入孔的内面，通过回撤冲头轻微向上卷起。
发明的一个特别优选的实施方式在于，周围区域大约有一个两倍于孔径的尺寸。因此周围的圆锥形角是足够大了，使得一方面使洗涤物从可达到的范围内充分地回来，另一方面在拉伸时，工具中的孔边能被充分地拉回来。这也是另一个按照本发明的洗涤滚筒的目标，其中平坦成形的孔边缘有这样一个区域，该区域属于孔径的一部分。
以一种特别有利的方式，将用一种工具中满足按照发明的洗涤滚筒的要求，其中作为冲制U形或截锥状孔形和切出孔口的冲头将这样引入冲套中，其中冲头先于冲套置在壁板上，并且冲套有一斜的前端面，它的直径小于孔的周围区域的外径。
借助于一个在示意图中示出的例子，发明将在后面阐述。
其中：
图1按现有技术水平的在工具中的洗衣机洗涤滚筒的流水孔；
图2类似于图1也在工具中的，但按本发明的洗衣机洗涤滚筒流水孔的结构形式；和
图3图2中III区的详细放大图。
如图2和图3所示，按照本发明孔边缘7的平面形状在外侧边6也有象目前技术水平的边棱。但通过工具的特殊制造，它对洗涤物和指尖将没有危险。为此工具的上半部分8中另外安装有一个冲套9，它将随冲头3之后压在滚筒壁板上。首先冲头3将孔边7拉成了一个向外的圆锥状，直到壁板1到达支架，然后在冲套9将孔边7拉深到支架4之前，冲头3切出了孔截面5。对此将延长截锥的子午线，因为这一子午线通过冲套9拉成的形状被拉得更低了。但为此使孔边7的边缘6从冲头3中往回拉了一个约0.1~0.2mm的距离T，同时带动它的边棱11，这种边棱是通过支架的边拉成并指向孔心的。一旦冲头重新往上运动时，它的外表面与边棱11产生摩擦并将其从孔底下往回拉了一些，也是在指向孔心的方向上。由此就可以完全避免了指尖的割破。可以发现，这样冲压得到的孔底使得那些可能到达边棱11的织物纤维又从它那里排开，从而也排除了割断织物纤维的可能性。
按照本发明在洗衣机洗涤滚筒中制得作为流水的孔通常是开在洗涤滚筒(没有表示出来)外壳上的。另外这些孔也能开在洗涤滚筒的一个或两个底板上。相反，一个洗涤甩干机的滚筒中，这一类的孔只开在底板上，通过这些孔热风会被吹入洗涤滚筒中。

Claims (5)
