TPU embossing machine.What should be paid attention to when making embossing rolls?

　　1. Blanking: The embossing roller body is made of seamless steel pipe, the shaft is made of 45 round steel, and the end plate is made of Q235 steel plate. A machining allowance of 8mm is reserved according to the drawing size for cutting.

　　2. Turning processing: Turning the mating surfaces of the embossing roller body, end plate, and shaft, and processing them according to the H9/f9 mating accuracy.

　　3. Weld the reinforcing ribs and two end shafts inside the combined embossing roller body, pay attention to correcting the coaxiality between the two end shafts and the inner sleeve, and only weld the inner end plate on the shaft.

　　4. Install the fully welded inner sleeve into the embossing roller body, and weld the joint between the inner end plate and the embossing roller body.

　　5. 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 the embossing roller body.

　　6. Anneal the blank of the embossing roller for welding combination to eliminate internal stress.

　　7. One end of the steel roller shaft of the embossing roller is turned flat and a standard center hole is drilled.

　　8. Turning processing: Roughly and finely turn the various parts of the embossing roller steel body to the dimensions required in the drawing. The working surface roughness of the embossing roller body should not exceed 1.6 μ M; The radial runout tolerance of the working surface of the embossing roller on both ends of the shaft support surface (rolling bearing installation position) is 0.025mm; The roundness of the working surface of the embossing roller body is 0.036mm; The matching circle of the bearing is processed with a precision of k6. Then frame the center frame and drill the end face to the size.

　　9. Press the pattern requirements of the flower roller steel roller to process the pattern. Then, a hard chromium layer is plated with a thickness of 0 03-0.05mm.

　　10. Correct the static balance of the embossing roller steel roller.
