引言旋轉的弯曲和校正机械,广泛地被应用在机械製造工業中;特別是造船工業、鍋爐製造工業。也使用在重工業、运輸業、和農業的机器制造中。旋轉的弯曲机械种類很多,總的說來,有弯曲机与弯捲机兩种。弯曲机可分为型鋼弯曲机与管子弯曲机等,它的工作情况如[图一]。弯曲桿件一端被夾緊在一定半徑的心軸或模子上,当旋轉心軸(轉盤)或在桿件另一端加力時,桿件就会圍繞着心軸或模子弯曲。
INTRODUCTION Rotating bending and correcting machines are widely used in the machinery manufacturing industry; in particular, the shipbuilding industry, the boiler manufacturing industry. Also used in heavy industry, transportation, and agricultural machinery manufacturing. There are many kinds of rotating bending machines. Generally speaking, there are two kinds of bending machines and bending machines. Bending machine can be divided into steel bending machine and pipe bending machine, etc., its work as shown in [Figure 1]. One end of the bent rod is clamped on a mandrel or mold of a certain radius, and when the mandrel (turntable) is rotated or energized at the other end of the rod, the rod will be bent around the mandrel or mold.
