Description
技术领域
本发明涉及一种空腔复合构件，该构件至少由单件或多件由金属或塑料制成的空心型件和需要时空心型件内部的单件或多件由金属或塑料制成的支承部件组成，其中该支承部件与空心型件和/或空心型件部件相互之间用热塑性塑料形状相合地加以连接。此外本发明还涉及制备这种空腔复合构件的方法。
背景技术
如由DE-A 19848516己知这种空腔复合构件。为将半壳件与盖板或盖壳连接使用了注入的热塑性塑料。为此该半壳件和盖板例如具有围缘，该围缘设有通孔，在该通孔中可实现由例如注入的塑料形成的铆接。可供选择地或附加地还可提供卷边，在该卷边上也可由注入的塑料形成抗剪切的形状相合的连接。此外由DE-A 19848516还己知其它用于连接两个或多个模制件的方法如焊接、粘合、卷边、紧钳、铆接，其可单独用于或组合用于模制件的连接。
可承受高机械应力的空腔-轻型构件可用作例如飞机制造中。
发明内容
本发明的目的在于提供一种空腔复合构件，其模制件以高的接合准确性相互连接。该空腔复合构件应能以尽可能简单的方法制备。
本发明的主题是一种空腔复合构件，该构件至少由单件或多件由金属或塑料制成的空心型件和需要时在该空心型件内部的单件或多件由金属或塑料制成的支承部件组成，其中该支承部件与空心型件和/或空心型件部件相互之间用热塑性塑料形状相合地加以连接，其特征在于，该支承部件与空心型件和/或空心型件的部件通过在注入热塑性塑料时至少一个空心型件部件的塑性变形实现连接。
本发明的空腔复合构件具有单件或多件由金属或塑料制成的空心型件。该空心型件可能是开口的如半壳件或辊压型件，或可能是闭合的如具有任意横截面如圆形或四边形横截面的管。单件空心型件例如可以是管。多件空心型件例如由两个半壳或由一个半壳和一个盖板组成。空心型件可呈任意的三维形状。此外，多个空心型件可相互连接并形成复杂的三维空腔如具有支路。如果该空心型件由多件组成，则该各空心型件部件如两个半壳件由注入的热塑性塑料形状相合地进行相互连接。
在本发明的空心型件的内部需要时可存在至少一个由金属或塑料制成的支承部件。该支承部件经注入的热塑性塑料与空心型件形状相合地相连接。该支承部件可以是单件或多件。此外该支承部件还可以制成实心的或带有空腔、通道等。在该支承部件的相应几何形状如交叉形横截面下，该支承部件可将空心型件再分成多个通道，这些通道例如用作电缆通道或空气通道。该支承部件可部分或完全安装在空心型件的内壁上。例如可于作支承空心型件耐受注入塑料的喷注压力，因为在喷注其它模制件或空心型件过量喷注时会遇到不希望有的塑性变形。在此情况下该支承部件优选仅安装在内壁上的区域，在此区域中该空心型件的外部喷注有其它模制件或对空心型件进行喷注包封。该支承部件的几何形状的选择要使其在空心型件中起到耐受塑料喷注压力的支承功能。该支承部件也可用以改进空心型件的刚性和强度。
按本发明，该支承部件与空心型件和/或该各空心型件部件相互间的形状相合的抗剪切连接是通过在注入热塑性塑料时至少一个空心型件部件的塑性变形实现的。如果该空心型件是多件的并例如由两个半壳件或一个半壳件和一个盖板组成，则该空心型件部件例如在两型件部件叠置或对置的边缘区相互连接。这时该型件部件之一在其边缘区有被另一型件部件所遮盖的通孔和/或卷边。同样一个或另一个型件部件可交替地具有分别被另一型件部件遮盖的通孔和/或卷边。通过在注入热塑性塑料时的喷注压力，在通孔区中该遮盖通孔的型件部件经塑性变形，由此被压入通孔中。该塑料的喷注压力很大，使得由金属或塑料制成的型件部件在喷注点区域发生变形。为此该注塑模具的模腔在通孔区具有所注入的塑料不可进入的空腔。通过塑性变形产生该两型件部件的形状相合的耐剪切连接。
因此，在一个优选实施方案中，该空心型件是两件式的，并且该两个空心型件部件在边缘区相邻放置，其中一个空心型件部件的边缘区有通孔和/或卷边，另一空心型件部件通过注入热塑性塑料在通孔和/或卷边的区域发生塑性变形。
对本发明的复合构件在由金属或金属合金制成的空心型件部件情况下，其壁厚的数量级可达2mm。在由塑料制成的复合构件情况下壁厚甚至可达4mm数量级。此外，在数量级达2000bar的喷注压力和/或相对较薄的模制件如由厚度为0.4-1mm的薄钢板制成的模制件情况下，也可能使在边缘区叠置或相邻放置的两个模制件一块发生塑性变形，而在两个模制件之一中未提供有通孔和/或卷边。
支承部件可以类似的方式与空心型件发生连接。为此该支承部件在塑性变形区中未连在空心型件的内壁上，而是具有例如通道、空隙等形状的空腔。在从外面喷注塑料时，该空心型件在支承部件的空隙区中发生塑性变形，由此该空心型件被压进空隙等处。
本发明的带支承部件的空心型件可经部分或全部喷注包封。这样，在喷注塑料时该支承部件可支承该空心型件免于压扁或不希望的变形。
该模制件的优选金属是钢、镍、铬、铁、铜、锌、钛、铝和镁以及这些金属的合金。
适于该模制件的优选塑料是非增强的、增强的和/或经充填的热塑性塑料制成，例如聚碳酸酯(PC)、热塑性聚氨酯(PU)、聚酯特别是聚对苯二甲酸乙二醇酯(PET)、聚苯乙烯(PS)、间同聚苯乙烯、丙烯腈-丁二烯-苯乙烯(ABS)、聚环氧丙烷(PPO)、聚砜(PSO)、聚苯硫(PPS)、聚酰亚胺(PI)、聚酮(PEEK)、聚酰胺(PA)、聚对苯二甲酸丁二醇酯(PBT)、聚丙烯(PP)、聚乙烯(PE)或这些塑料的混合物。
适于模制件形状相合的相互连接的热塑性塑料特别是基于下列的非增强的、增强的和/或经充填的塑料：聚酰胺(PA)、聚酯特别是聚对苯二甲酸乙二醇酯(PET)、聚对苯二甲酸丁二醇酯(PBT)、聚苯乙烯(PS)、间同聚苯乙烯、丙烯腈-丁二烯-苯乙烯(ABS)、聚对苯二甲酸丁二醇酯(PBT)、热塑性聚氨酯(PU)、聚烯烃特别是聚丙烯(PP)、聚乙烯(PE)、聚碳酸酯(PC)、聚环氧丙烷(PPO)、聚砜(PSO)、聚苯硫(PPS)、聚酰亚胺(PI)、聚醚醚酮(PEEK)或这些塑料的混合物。
本发明的另一目的是提供一种用于制备空腔复合构件的方法，该构件至少由单件或多件由金属或塑料制成的空心型件和需要时在空心型件内部的单件或多件由金属或塑料制成的支承部件组成，其中该支承部件与空心型件和/或空心型件部件相互之间用热塑性塑料形状相合地加以连接，其特征在于，该支承部件与空心型件和/或空心型件部件在注入热塑性塑料时通过至少一个空心型件部件的塑性变形实现连接。
该支承部件与空心型件和/或空心型件部件相互间的形状相合的连接是以一步工艺步骤在空心型件上注塑一个或多个模制件而实现的。在该方法的实施方案中，形状相合的连接和其他模制件的注塑的两种工艺步骤是以一步完成的。在该空腔复合构件上可注塑的其它模制件优选由塑料例如非增强的、增强的和/或经充填的热塑性塑料如聚碳酸酯(PC)、热塑性聚氨酯(PU)、聚酯特别是聚对苯二甲酸乙二醇酯(PET)、聚苯乙烯(PS)、间同聚苯乙烯、丙烯腈-丁二烯-苯乙烯(ABS)、聚环氧丙烷(PPO)、聚砜(PSO)、聚苯硫(PPS)、聚酰亚胺(PI)、聚酮(PEEK)、聚酰胺(PA)、聚对苯二甲酸丁二醇酯(PBT)、聚丙烯(PP)、聚乙烯(PE)或这些塑料的混合物或金属如钢、镍、铬、铁、铜、锌、钛、铝和镁以及这些金属的合金组成。
本发明的空腔复合构件的优点在于，该模制件以高精度和可再现性相互连接，并且不需对接合部位作相互的调整。其精确性高于采用分开的接合工艺如焊接操作或铆接操作的情况。此外，本发明的用于制备空腔复合构件的方法的优点在于，型件部件的相互连接和支承部件与空心型件的连接以及其它模制件的注塑是以一步完成。因为在注入塑性包封或在注塑其它模制件时该支承部件同时支承空心型件免受不希望的塑性变形，所以无需采取其它的抗空心型件变形的预防措施如安置用于支承空心型件的实心杆，该实心杆在注塑后必须再次去除。
将依下列附图对本发明进行详述。
附图说明
图1示出本发明的由两个半壳件组成的空腔复合构件的部分横截面图，其在边缘区形状相合地相互连接。
图2示出本发明的由两个半壳件和一个支承结构组成的空腔复合构件的部分横截面图，其中支承结构和空腔型件形状相合地连接。
具体实施方式
图1示出由两个半壳件1，1’组成的空心型件10的局部图，该半壳件如由金属如钢、镍、铬、铁、铜、锌、钛、铝和镁或者这些金属的合金组成或由非增强的、增强的和/或经充填的热塑性塑料如聚碳酸酯(PC)、热塑性聚氨酯(PU)、聚酯特别是聚对苯二甲酸乙二醇酯(PET)、聚苯乙烯(PS)、间同聚苯乙烯、丙烯腈-丁二烯-苯乙烯(ABS)、聚环氧丙烷(PPO)、聚砜(PSO)、聚苯硫(PPS)、聚酰亚胺(PI)、聚酮(PEEK)、聚酰胺(PA)、聚对苯二甲酸丁二醇酯(PBT)、聚丙烯(PP)、聚乙烯(PE)或这些塑料的混合物组成。半壳件1，1’具有弯曲的边缘区2，2’。半壳件之一1’在其边缘区2’中具有通孔3。在用热塑性塑料4进行注塑和喷注包封边缘时，该半壳件1通过喷注压力压入通孔3中，并从而使卷边6发生类似的塑性变形。以此方式使两个半壳件相互形状相合地和耐剪切地连接。
在图2(相同或类似构件以相同标号表示)中，空腔复合构件10’由两个半壳件1，1’和一个在空心型件10’内部的支承部件5组成。该半壳件1，1’例如由金属如钢、镍、铬、铁、铜、锌、钛、铝和镁或者这些金属的合金组成或由非增强的、增强的和/或经充填的热塑性塑料如聚碳酸酯(PC)、热塑性聚氨酯(PU)、聚酯特别是聚对苯二甲酸乙二醇酯(PET)、聚苯乙烯(PS)、间同聚苯乙烯、丙烯腈-丁二烯-苯乙烯(ABS)、聚环氧丙烷(PPO)、聚砜(PSO)、聚苯硫(PPS)、聚酰亚胺(PI)、聚酮(PEEK)、聚酰胺(PA)、聚对苯二甲酸丁二醇酯(PBT)、聚丙烯(PP)、聚乙烯(PE)或这些塑料的混合物组成。该支承部件5例如由金属如钢、镍、铬、铁、铜、锌、钛、铝和镁或者这些金属的合金组成或由非增强的、增强的和/或经充填的热塑性塑料如聚碳酸酯(PC)、热塑性聚氨酯(PU)、聚酯特别是聚对苯二甲酸乙二醇酯(PET)、聚苯乙烯(PS)、间同聚苯乙烯、丙烯腈-丁二烯-苯乙烯(ABS)、聚环氧丙烷(PPO)、聚砜(PSO)、聚苯硫(PPS)、聚酰亚胺(PI)、聚酮(PEEK)、聚酰胺(PA)、聚对苯二甲酸丁二醇酯(PBT)、聚丙烯(PP)、聚乙烯(PE)或这些塑料的混合物组成。
支承部件5与空心型件10’通过半壳件1，1’的塑性变形9，9’形状相合和耐剪切地连接。该塑性变形9，9’在以热塑性塑料8过量注入空心型件10’中时实现。在该实施方案中，该支承部件5具有通道7。在通道7的区域中该支承部件5在从外部注入热塑性塑料8时未从内部提供对注入压力的反压力，以使在该区区域9，9’中半壳件1，1’被压进通道7中。
