Ten embossing machine embossing process affect the quality of steel rod

In their daily work, there are many people for embossing machine embossing iron bars which attention to points not know much about the production process, the following in order to manufacture embossing machine iron bars should note the following ten simple description of the process to the next :

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

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

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

Four Turning: Turning roller body parts with the end plate and the shaft member of the joint surface, according to H9 / f9 with precision machining.

V. end of the car flattened ends of steel rollers, the standard drill hole center.

VI. The outer end plate mounted at both ends of the shaft, the outer end plate welded joint surface at the junction of the shaft and the roll body.

VII. Welding combination roller blank annealing treatment to eliminate internal stress.

Eight steel roller static balance correction.

Nine Turning: sub-thick, steel roll finishing each part of the body to the required size drawings. Surface roughness of the work roll should be less than 1.6μm; 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.

X. Press pattern pattern steel roll processing requirements patterns. Then hard chrome plating layer thickness of 0.03 ~ 0.05mm.

Only in the production process in strict accordance with the relevant process operation, in order to ensure the quality of the steel roller embossing machine.
