Abstract

本发明在最广义上可被定义为一种生产具有由片材制成的曲折起皱芯(2)的夹板的方法，这种方法被用于飞机建造、造船和其他行业。其目的在于提高产品质量，并且通过在芯片坯件中、在突部和凹部的褶皱曲折线(4)的位置处冲一些孔，使得芯片坯件容易折叠成三维起伏结构，所冲的这些孔的直径不小于芯片坯件的弯曲半径。

Description

生产具有曲折起皱芯的夹板的方法
技术领域
本发明在最广义上可被定义为一种生产具有由片材制成的曲折起皱芯的夹板的方法，这种方法被用于飞机建造、造船和其他行业。
背景技术
用于生产具有曲折起皱芯的夹板的方法包括分别形成芯层和外皮，其中，通过把板片坯件沿着所划出的突部和凹部曲折线进行弯曲来制造所述芯，这种方法被当作原型(SU发明证书No.1,830,326A1，具有曲折起皱芯的曲线状夹板的制造方法，国际分类号为B23K20/00，93年7月30日的公告第28条)。
这里所描述的方法的主要缺点在于，由于在节区中的延展效应，因而增加了材料。当起皱芯在其节区中成形时，就出现了这种效应，所述的节区是指折叠结构的至少四个突脊会聚处和同时在两个平面中发生弯曲处。由于芯与外皮之间的点接触，因而这种效应导致了夹板强度的降低，所述的点接触是由于它们仅在节区中互相连接，而不是沿着突部和凹部线互相连接的缘故。此外，由于必需施加相当大的作用力来使坯件成形，因而坯件材料变形的条件很不利；这导致了在这个区处的压力集中，并且不利地影响了芯-外皮的连接强度。
发明内容
本发明由于消除了两个平面中的弯曲区，从而改善了芯的成形条件，并且加强了芯-外皮的连接强度，这就是本发明的目的。
我们的发明所获得的技术效果是提高了具有折叠结构芯的夹板的产品质量。
这里所述的技术效果是通过一种用于生产具有曲折起皱芯的夹板的方法来获得的，这种方法包括分别形成外皮和芯，然后在获得所规定的褶皱轮廓时把所形成的外皮和芯连接起来，所述的褶皱轮廓是通过使芯片坯件沿着在展开的芯上所划出的曲折线进行弯曲来获得的，-根据这个技术方案：在曲折起皱芯展开的芯片坯件中、在弯曲线的相交处冲出一些孔，这些孔的直径为dh≥Rb，其中，Rb是芯片坯件的最大弯曲半径。
申请人通过对现有技术的分析，表明现有技术中没有与本发明中的特征组合相类似的特征组合。因此，所要求保护的技术方案满足专利性中的“新颖性”条件。
通过在给定领域检索与所要求保护的技术方案的特征部分相同的技术特征，检索结果表明所要求保护的技术方案的特征部分的技术特征并不是来自于现有技术。从申请人尽力揭露的现有技术来看，所确定的必要技术特征对所声称的技术效果没有影响。因此，本发明所要求保护的技术方案满足专利性中的“创造性”条件。
附图说明
图1-4表示出了本发明的要素。
图1是具有曲折芯的夹板的总体示意图(图中未表示出上部外皮)；
图2表示带有一些孔的芯的扁平坯件，所述的一些孔位于突部和凹部的褶皱曲折线的点处；
图3是图1的A-A剖面图；
图4是图1的A-A剖面图的按比例放大示意图I。
图1-4表示出了下列位置：
1是下部和上部(图中未示)外皮；2是起皱的芯；3是褶皱突部的曲折线；4是褶皱凹部的曲折线；5是锯齿状线；6是芯片坯件；7是位于曲折线和锯齿状线的位置处的一些孔；8是具有粘附性能的复合材料。
具体实施方式
所要求保护的方法能以下列方式来实现：
1)制造出夹板的外皮和内皮1；
2)在芯片坯件6上划出弯曲线3、4、5，所述的芯片坯件6具有平面状态下的芯2的尺寸大小；弯曲线3、4、5的参数和相对位置与已制造好的芯2的设计参数有关：
Ld＝f(H，L)；Vd＝f(V，Ld)；Sd＝f(V，S，H，L)，
其中，H是曲折褶皱的高度，V是曲折线的幅度，2S是曲折线之间的步距，2L是芯的锯齿状线之间的步距，2Sd是曲折线之间的步距，Ld是曲折线之间的距离，Vd是展开的芯上的曲折线的幅度；
3)在坯件中、在锯齿状线5和曲折线3、4的交点处冲一些孔7；这些孔7的直径为dh≥Rb，其中，Rb是在已制造好的芯2中的锯齿状线5和曲折线3、4交点处的芯片坯件的弯曲半径；
4)使芯片坯件6成形，直到形成芯的三维起伏结构；
5)把所获得的芯的折叠结构与外皮和内皮1连接起来，例如，利用具有粘附性能的复合材料8来连接。
工业实用性
所要求保护的用于生产具有曲折起皱芯的夹板的方法能被用于飞机夹板的工业生产。基于所要求保护的方法制造出的设备提高了曲折起皱芯的产品质量并且增加了夹板的强度。
