一种制造金属扁管的装置和方法制造方法及图纸

一种制造金属扁管的装置及方法。该方法具体为：提供一片材，然后将片材碾压成型并焊接为圆形管材，最后将圆形管材通过拉伸模具的通孔进行拉伸，通孔为长条形状，其长度大于宽度，且长条形状的通孔的宽度小于圆形管材的直径，以将圆形管材拉伸为扁管。因此，通过上述方法及装置，将圆形管材通过拉伸模具进行拉伸为扁管，方法简单，并且模具成本低。

A device and method for making metal flat tubes

A device and method for the manufacture of a metal flat tube. The concrete method is: to provide a sheet, and the sheet rolling forming and welding for circular pipe, the circular pipe tensile drawing die through the through hole, the through hole is elongated shape, its length is greater than the width of the through hole, and the shape of the strip width is smaller than the diameter of the circular pipe, round pipe for drawing flat tube. Therefore, through the above method and device, the circular pipe is stretched into a flat tube through a drawing die. The method is simple and the cost of the die is low.
