トラック チェーン/リンクの鍛造プロセス

現在のところ, there are two main processes to produce excavator track chain links, 1つは鋳造で、もう1つは鍛造です.
ここ, let’s briefly introduce the forging process.
Firstly, 棒材を加熱し、NC鍛造ハンマーの金型に載せて鍛造する. 初期鍛造・精密鍛造後, it can be forged to track link for excavator ご不明な点がございましたら.

NC鍛造ハンマーのスピードが速い, and the shape variable of forged track chain assy is high, which fully changes the internal structure of excavator chain link and increases the density of forging. There will be no loose structure, coarse grain, shrinkage porosity, porosity and other problems. したがって, the forged excavator track chain link has higher hardness and stronger wear resistance.
