鋁型材的拉伸拉彎怎么樣-?？诤Ｋ嚴瓘澪褰鹬破酚邢薰?/title> <meta name="keywords" content="?？诶瓘??？诶瓘潖S家,?？诶瓘潈r格"/> <meta name="description" content="鋁型材拉伸彎曲成形的基本原理是將拉伸彎曲模與工作臺固定，臂部拉伸型材圍繞拉伸彎曲模旋轉，在拉伸和彎曲力矩的作用下，使型材毛條發生塑性變形，并逐漸與模具配合，從而獲得e所需形狀零件。拉伸彎曲件的特點是彎曲半徑大、回彈大、彎曲伸長軸變化大。鋁型..."/> <meta name="viewport" content="width=device-width,
