EN 10346: 2015 DX52D+Z Plakaların Form-Punta Bağlantı Performansları

Bu çalışma, şekillendirme kabiliyeti nedeniyle daha çok otomotiv endüstrisinde tercih edilen çinko kaplanmış farklı kalınlıktaki EN 10346:2015 DX52D+Z kalite çelik levhaların clinching teknolojisi ile yapılan bağlantılarının bağlantı kalitesi üzerine yapılmıştır. Özellikle clinching uygulamalarında karşımıza çıkan farklı pozisyon ve farklı kalınlıktaki levha birleştirmelerindeki bağlantı problemleri ele alınmış ve bağlantı kalitesi için genel bir değerlendirme yapılmıştır. Standartlara uygun olarak gerçekleştirilen testler sonucunda birbirlerine yakın kalınlıktaki levhaların bağlantılarının nispeten iyi olduğu, kalınlık farkının arttığında, bağlantı kalitesinin azaldığı ve bazen bağlantıların gerçekleşmediği görülmüştür. Bağlantı sırasında daha ince olan plakanın alt matris tarafında olması, çok daha iyi bir bağlantı dayanımının sağlanabilmesinin bir gereği olduğu belirlenmiştir.

The Clinching Joints Strength Performance of EN 10346: 2015 DX52D + Z Sheets

This study is based on the joint quality of zinc-coated EN 10346: 2015 DX52D + Z quality steel sheetswith having different thicknesses, which are preferred in the automotive industry due to theirformability. Joining problems in clinching applications with different positions and sheets of differentthicknesses are discussed and experimental outcomes are discussed in terms of strength of joints. As aresult of the tests carried out according to the standards, it has been found that the joining of the sheetswith thickness close to each other is relatively good, as the thickness difference increases, the jointquality decreases and sometimes the joint does not form. It has been also found that if the thinnersheet is placed on the bottom die during clinching, a better joint strength is obtained.
