When installing the pipe, the two pipe connections need to be welded. In order to ensure the welding strength, especially the pressurized pipe, it must be chamfered and welded. Generally, it is blown by oxyacetylene or chamfered by a welding machine electrode, and it is also a hand-cranked chamfer by a fitter. The first two methods have poor chamfer quality and are not flush. The latter is good, but it is laborious and laborious. Special tools that are not chamfered on the market are sold. To solve this problem, a special pipe chamfer is designed.
The tool uses a 12° inner and outer cone to inflate the inner wall of the tube to fix the mandrel. The outer cone is divided into six lobes, that is, a hexagonal groove column. The column width is 3 mm. At the root of the column, that is, the concave column of the cone, a hole of 4 mm is drilled. . The use of the chamfering device is between 45 and 80 mm of the inner diameter of the tube, and the structure is shown in the drawing.
How to use: Clamp the tube that needs to be chamfered on the gantry, insert the mandrel with the inner and outer cones of the chamfer into the tube to be chamfered, and position it. The wrench is fixed to the mandrel, and the M16 screw is tightened so that the inner hole cone is inflated to the inner wall of the tube. For the two chamfering knives and screw them tightly, put the handles of the two tubes together and screw them into the handle body. 5毫米的普通管The chamfering device can be completed by rotating 3 to 4 turns.

After the chamfering is completed, the mandrel is also fixed with a wrench, the M16 nut is loosened, and the end face of the screw is tapped with a hammer to loosen the two cones of the expansion, and the mandrel can be withdrawn for the next chamfering.
If the outer angle of the different pipe diameters is reversed, the outer cone can be replaced, and the outer cone can be replaced. The newly replaced outer cone must be consistent with the original taper. The recessed column is kept 2 to 3 mm and the column width is 5 mm.
