彎曲镦鍛法是生産大型船用曲軸的重要加工方法之一。
Upset forging(镦粗鍛造)是一種金屬塑性成形工藝,通過沿軸向壓縮金屬坯料,使其局部橫截面積增大、長度縮短,常用于制造法蘭、螺栓頭部等需局部增厚的零件。其核心原理是利用模具對加熱後的金屬坯料施加壓力,使材料在受壓區域流動并填充模腔,從而改變形狀并提升機械性能。
該工藝在工業中的應用包括:
相較于傳統鍛造,upset forging能有效提高材料利用率并減少後續加工步驟,但需精準控制溫度與壓力以避免内部缺陷。其技術參數通常遵循ASTM E8或ISO 6892-1等國際材料測試标準。
"upset forging" 是一個金屬加工領域的專業術語,其含義和用法可通過以下維度解釋:
