How is the embossing roller made

　　1. Cutting: roll body with seamless steel pipe, shaft head with 45# round steel and two ends of the flange

　　2. Turning processing: turning the combination surface of the matching parts of the roller body, end plate and shaft,

　　3. Welding processing: (According to the drawings, if there is a structure such as oil or water flow inside the roller body, it is necessary to carry out internal pipe welding processing in advance)

　　Roll tube welding: correct the coaxiality between the two ends of the shaft and the inner sleeve, and only weld the inner end plate of the shaft head.

　　Insert the inner part into the roller body and weld the mating junction between the inner end plate and the roller body.

　　The outer end plate is mounted on both ends of the shaft, and the junction of the outer end plate with the shaft and the roller body is welded.

　　4, roll blank annealing treatment, eliminate internal stress.

　　5. One end of the steel roller is flat and the standard center hole is drilled.

　　6, turning processing: rough, fine steel roller body parts to the drawing requirements of the size, and then frame the center frame, the end face, drilling to the size.
