该机主要用于通风管道椭圆形风管的制作，风管经螺旋成型后，

在该椭圆风管机一次性扩张成型至客户所需的椭圆风管的标准尺

寸，具有成型好，效率高，操作简便等优点，是通风管道生产中

不可缺少的设备。

It is used for the ovalizer duct manufacturing.After

spiral duct,the ovalizer duct machine expands it into

standard size,with the character of good shape,high

efficiency,easy operation.It is indispensable for duct

manufacturing.

1、小型的椭圆螺旋风管成型机能满足大多数风管加工生产的

要求，加工成型直径在330mm到1500mm之间

1, Small compact helix ovalizer can satisfy requirements

of most ductwork.The former diameter is between 330mm

and 1500mm.

2、小型椭圆螺旋风管对生产场地的空间要求小，能加工长

3.0m，厚度达1.2mm的风管。

2, Small compact helix ovalizer has less requirement of

area.It can be processed duct with width of

3.0m,thickness of 1.2mm
