螺旋缝风管轧制机是将带钢卷制成螺旋缝圆风管的专用机械。它由四部分组成①送料及咬口成型机构;②螺旋角微调机构;③圈圆成型机构;④自动切割跟踪机构。每一部分单独有一电机作动力。另外还有带钢支架及管道支架。铁皮带钢由送料机送入,卷成螺旋形咬口的风管后输出。螺旋形圆风管的特点是有很高的结构强度和刚度,因此同通常的直缝圆风管相比,用的钢板厚
Spiral seam duct rolling machine is a special machine that uses steel coils to make spiral seam circular ducts. It consists of four parts 1 feed and bite mouth forming mechanism; 2 spiral angle fine-tuning mechanism; 3 circle round molding mechanism; 4 automatic cutting tracking mechanism. Each part has a separate motor for power. There are also strip brackets and pipe brackets. The iron belt steel is fed by the feeder, and is output after being wound into a spiral ducted air duct. The spiral round duct is characterized by a high structural strength and rigidity, so the steel thickness used is greater than that of a normal straight seam circular duct.
