TPU solding machine wholesaler.How is the embossing roller made

　　1. Blanking: The roller body is made of seamless steel pipe, and the shaft head is made of 45 # round steel and flange plates at both ends

　　2. Turning processing: Turning the mating surfaces of roller bodies, end plates, and shaft heads,

　　3. Welding processing: (According to the drawing, if there are oil or water structures inside the roller body, the inner tube welding processing needs to be carried out in advance)

　　Welding of the inner tube of the roller: Correct the coaxiality between the two ends of the shaft and the inner sleeve, and only weld the inner end plate on the shaft head.

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

　　Install the outer end plate on both ends of the shaft and weld the junction surface between the outer end plate and the shaft and roller body.

　　4. Perform annealing treatment on the roller blank to eliminate internal stress.

　　5. One end of the steel roller shaft is turned flat on the end face and a standard center hole is drilled.

　　6. Turning processing: Roughly and finely turn each part of the steel roller body to the size required in the drawing, then frame the center frame, turn the end face, and drill to the size.

　　7. Process patterns on the surface of the roller according to customer pattern requirements. This is a crucial part of the embossing roller production process, requiring the embossing roller production personnel to have rich experience and develop production processes based on customer pattern requirements. In the production process, the embosser should be careful, meticulous, and meticulous, and the patterns produced should have clear patterns, rich layers, and strong three-dimensional sense.

　　8. After the pattern is completed, the surface of the roller body is plated with a hard chromium layer or sprayed with other materials (depending on the purpose of the customer's embossing roller)

　　9. Correct the static balance of the steel roller
