The laser engraving 3D embossing roller is used for the blanking of the roller body. The roller body is made of 45 round steel, the end plate is made of Q235 steel plate, and 8mm machining allowance is cut according to the drawing size. Turning processing: The joint surface of the joint part of the turning machine body, the end plate and the shaft is machined according to the precision of H9/f9.
The laser-engraved 3D embossing roller is welded to the ribs and the shafts at both ends of the roller. Pay attention to correcting the coaxiality between the shafts at both ends and the inner sleeve, and only the inner end plate on the shaft. The inner part of the combined welding is fitted into the roller body, and the joint end of the welded inner end plate and the roller body is combined.
The outer end plate of the laser engraved 3D embossing roll is mounted on the shafts at both ends, and the outer end plate is welded to the joint surface of the shaft and the roller body. The roll blank of the welded combination is annealed to eliminate internal stress. One end of the steel roller shaft has a flat end face and a standard center hole is drilled.
Turning of laser-engraved 3D embossing rolls: Dividing the parts of the coarse and fine steel rolls to the required dimensions of the drawings. The working surface roughness of the roller body should be no more than 1.6μm. The radial running tolerance of the roller supporting surface (rolling bearing mounting part) is 0.025mm, and the roundness of the roller working surface is 0.036mm. The circle is machined to k6 precision. Then the center frame, the end of the car, drilled to size.
