Radyal perçinleme işlemine basınç ve zamanın etkisi

Radyal perçinleme üretim metodu özellikle otomotiv üretim sektöründe sıkça kullanılmaktadır. Farklı veyaaynı malzemeden üretilmiş olan parçalar perçinle bağlandığında, ilgili parçalara hasar verilmeden veyabağlantı noktası tahrip edilmeden birbirlerinden ayrılmaları mümkün değildir. Perçinleme işleminin teknikolarak optimal olabilmesi için makine tarafından perçine uygulanan basıncın değeri ve uygulama süresibüyük önem taşır. Radyal perçin bağını oluşturmak için tasarlanmış yeni bir pnömatik perçinlememakinesinin süreç çıktılarını kontrol etmek amacıyla süreç parametrelerinin belirlenmesinde kullanılandeneysel yaklaşım açıklanmıştır. Parametrelerin elde edilme yöntemi ve deneysel olarak gözlenen değerler,perçinleme ile ilgili literatürde ilk kez dikkate alınmış ve değerlendirilmiştir. Yayında, tasarım ve imalatıyapılan yeni bir radyal perçin bağı oluşturma makinesinin çalışma parametrelerini belirlemek amacıylaplanlanan denemeler ve sonuçları tartışılmıştır. Tam faktöriyel deneysel tasarım yaklaşımına dayanan planlı deneyler yoluyla, optimum kafa oluşumu için gerekli perçinleme basıncı ve süre değerleri belirlenmiştir.Tespit edilen bu değerlerin doğrulaması için de doğrulama denemeleri yapılmıştır

Effects of pressure and time on radial riveting process

Radial riveting production method is frequently used especially in the automotive industry. When parts madeof different or the same materials are connected with rivets, it is not possible to separate them withoutdamaging related parts or destruction of the joint. In the optimal riveting process, the value of the rivetingpressure applied by the machine on the rivet and the duration of the application are of great importance. Within this study an experimental approach used to determine process parameters to control the processoutputs in a new designed pneumatic riveting machine. The method of obtaining these parameters and theexperimental observed values were evaluated and considered for the first time in the riveting relatedliterature. In this paper, the planned experiments and its results for a new radial riveting machine, which wasrecently designed and manufactured, were discussed. Through planned experiments based on a full factorialexperimental design approach, the riveting pressure and the duration values required for an optimal headformation were determined. Verification tests have also been conducted to validate these specified values
