Using said structure, it is crooked and influence leveling effect and the circular arc degree of welded tube that welded tube is avoided well.
The utility model is further arranged to, and the connecting rod is connected with barred body by pin.
Using said structure so that barred body dismounting, change, be easy to maintenance.So that the utility model is applied widely.
The beneficial effects of the utility model:Compared to existing evener, the utility model cost is low, applied widely, knot
Structure is simple, energy-conserving and environment-protective and leveling effect are good.The outer circumference surface of topping roll and bottom roll is adapted to the external peripheral surface of welded pipe
Fitting can keep the circular arc degree of welded tube, prevent welded tube from deform welded tube when flattening weld seam.The outer circumference surface of first roller and weldering
Nozzle inner wall adaptation fitting, the circular arc degree of welded tube can be kept, prevents welded tube from deform welded tube when flattening weld seam.Weldering after welding
Pipe is cooperated with topping roll by the first roller and extruded so that weld seam flattens.Can using physical mechanical principle leveling weld seam
More energy-conserving and environment-protective, the pollutants such as the gas of pollution air will not be produced.First roller is axially fixed on barred body by pin,
It can be good at preventing that the first roller is axially moved, so as to avoid the effect for destroying weld seam leveling.Connecting rod and barred body
In being detachably connected, it is applied to the different caliber of welded tube by changing different barred bodies, it is of the present utility model so as to add
The scope of application.
