company news about What is the method of making seat holes for steel wheel spoke nuts?

The company has developed a method for making seat holes of steel wheel spoke nuts, which makes the nut seat holes not tilted and has high strength. Fix the inner side of the wheel spoke on the upper surface of the lower template horizontally arranged. Firstly, punch the nut seat stud stage holes on the wheel spokes, then punch the conical stage holes on the upper port of the nut seat stud stage holes, then punch the nut seat hemispherical stage holes in the conical stage holes on the nut seat, and then press the inner sleeve of the cylindrical stage die onto the positioning cam pillar and down to press down the convex edge of the upper port of the nut seat hemispherical stage holes. Stop pressing down the cylinder stage die when the lower end of the cylinder stage die is extruded. The result of pressing down the positioning punch column is to lower the height of the raised edge so that the raised edge height of the port on the nut seat hemisphere stage hole is equal.
