　　What do you need to pay attention to when making embossing rollers?

　　1. Cutting: the roller body is made of seamless steel pipe, the shaft is made of 45 round steel, the end plate is made of Q235 steel plate, and 8mm processing allowance is set aside according to the drawing size.

　　2. Turning processing: The combination surface of the matching parts of the embossing-roller body, end plate and shaft is processed according to H9/f9 matching accuracy.

　　3. Weld the reinforcement bar, both ends of the shaft and other parts of the roller body, pay attention to the correction of the coaxial degree between the two ends of the shaft and the inner sleeve, and only weld the inner end plate on the shaft.

　　4. Put the integrated welded inner package into the embossing roller body, and combine the welding inner end plate with the embossing roller body.

　　5. Install the outer end plate on the two ends of the shaft and weld the junction of the outer end plate with the shaft and the embossing-roll body.

　　6. Anneal the embossed roll blank of the welding combination to eliminate the internal stress.

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

　　8. Turning process: divide the parts of the steel roller body of the rough and fine turning embossing roller to the dimensions required by the drawing. The working surface roughness of the embossing roller body should not be greater than 1.6μm; The radial runout tolerance of the working face of the roller is 0.025mm on the support surface of both ends of the shaft (the mounting part of the rolling bearing). The roundness of the working surface of the embossing roller body is 0.036mm; The bearing fit circle is machined with k6 precision. Then frame the center frame, car end face, drilling to size.

　　9. According to the pattern requirements of the embossing roller steel roller processing pattern. Then plated hard chromium layer, thickness of 0. 03~0. 05mm.

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