Pnömatik Tahrikli Çekme Yayı Yorulma Makinesi Tasarım ve İmalatı

Öz

Bu çalışmada, bir çekme yayı yorulma makinesi tasarımı ve üretimi yapılmıştır. Çekme çeneleri pnömatik bir piston ile tahrik edilmektedir. Tasarlanan çalışma basıncı lokal pnömatik şebeke basıncı olan 6 bar’dır. En yüksek tahrik kuvveti 12 kN olarak tasarlanmıştır. Bu sayede, birçok yayı aynı anda test edilebilmektedir. Uygulanan kuvvet pnömatik hava basıncı ayarlayıcısı ile ayarlanabilmektedir. Yorulma döngüleri elektronik bir devre ile kontrol edilmektedir. Yorulma makinesi aynı zamanda belirlenen döngü sayısını tamamlaması için tasarlanmıştır. Bu nedenle, bir sayıcı kontrolcüye eklenmiştir. Makinenin her bir elementinin üretimi ve toleransları detaylı bir biçimde açıklanmıştır.

Design and Manufacturing of Pneumatic Driven Extension Spring Fatigue Machine

Öz

In this study, a tension extension spring fatigue machine was designed and manufactured. The force applied by jaws were driven by pneumatic piston. The air pressure is 6 bar that acquired from local pneumatic network. The maximum force was designed to meet at least 12 kN. Thereby, multiple quantity of extension springs can be tested simultaneously. The applied force can be adjusted pneumatic air pressure adjuster. The fatigue cycles were controlled by an electronic circuit. The machine is also designed to complement desired number of fatigue cycles. For this reason, a counter was also added to controller. Manufacturing of the machine elements and its tolerances were also described in detail.
