Polyoxymethylene (POM), as an energy-saving material, is widely applied in the manufacturing field. Yet, research on the rectangular clinching process between metal and POM sheets is still lacking. In this paper, the rectangular clinching process for POM and Al5052-H32 plates was investigated. The feasibility of the metal–polymer hybrid component had been analyzed in terms of diverse forming forces and diverse joint layout angles, respectively. The mechanical characteristics were appraised by the lap-shear test. The failure modes of rectangular clinched joints produced under diverse forming conditions had also been analyzed. The results showed that the optimal forming force of rectangular clinched joints was 14 kN, in which the lap-shear strength was 1090 N. Furthermore, the rectangular clinched joints produced under the joint layout angle of 90° could withstand the maximum lap-shear load (1415 N) under the optimal forming force. The failure mode was the separation of two plates and the fracture of the bridge structures.

金属和聚甲醛板的矩形压铆工艺研究

聚甲醛（POM）作为一种节能材料，广泛应用于制造领域。然而，仍然缺乏金属和POM板之间的矩形铆接工艺的研究。本文研究了 POM 和 Al5052-H32 板的矩形铆接工艺。分别从不同的成形力和不同的接头布局角度分析了金属-聚合物混合组件的可行性。通过搭接剪切试验评价机械特性。还分析了在不同成形条件下产生的矩形压接接头的失效模式。结果表明，矩形铆接接头的最佳成形力为14 kN，其中搭接剪切强度为1090 N。此外，在90°接头布置角下产生的矩形压铆接头在最佳成形力下可承受最大搭接剪切载荷（1415 N）。破坏模式是两块板的分离和桥梁结构的断裂。
