Production of embossed steel rolls which processes?

To manufacture embossed steel rod should note the following ten process:

1. Cutting: body roll seamless steel pipe, round steel shaft 45, the end plate Q235 steel, by drawing aside 8mm size allowance cut material.

2. Turning: Turning the matching portion of the roller body, end plate and shaft and other parts of the joint surface, according to H9 / f9 with precision machining.

3. The combination of roller body stiffener welding, shaft ends and other parts, pay attention to the correction shaft ends and inner sleeve coaxial, only welding the inner end plate shaft.

4. The combination of welding complete package within the roller body, in combination with the inner end plate welded junction of the roller body.

5. The outer end plate mounted on the bonding surface at the junction of the shaft ends, the outer end plate welded to the shaft and the roll body.

6. The combination of welding rolls blank annealing treatment to eliminate internal stress.

7. The end surface of one end of the car flat steel rollers, standard drilling center hole.

8. Turning: sub-rough, finishing all parts of the body to the steel roll size drawings. Surface roughness of the work roll should be less than 1.6¦Ìm; work roll face ends of the shaft support surface (Rolling installation parts) radial tolerance of 0.025mm; roundness roll body face is 0.036mm; bearing with round by k6 precision machining. Then frame center rack, facing, drilling to size.

9. Press pattern pattern steel roll processing requirements patterns. Then hard chrome plating layer thickness of 0. 03 ~ 0. 05mm.
