Super mirror roller, Dongguan Fuxiong rubber roller is the first choice

Super mirror roller processing technology
One component welding
Assembly and welding of the inner plate, shaft head bushing, blocking plate, inner tube, etc., the inner tube is statically balanced
within the inner tube, the inner tube is rotated To line, weld flat steel runner.
Second vehicle assembly welding
Interference between the inner tube size and the outer tube of the vehicle
Invert the weld angle of the two plates
Grind the inner tube, clean the slag and check the inner tube size Whether it is compatible with the inner diameter of the outer pipe, the heat sleeve is in place, and after cooling and shrinkage, the whole assembly is welded.
Note
Steel is heated before welding and kept warm after welding
Three annealing, rough turning and quenching
Annealing heat treatment, process quenching and tempering, multiple stress relief, leaving a margin for rough turning, and static If the balance is greater than
, it is necessary to calculate the offset amount and use the lathe to borrow the car.
Quenching
Surface hardness requirements
No cracks on the roller surface.
Four fine turning rough grinding
Trim the pinholes of the two spindle heads, and the two spindle heads run out against the roller surface,
, process the length to the size as required in the drawing, and leave an allowance on the outer circle, br/ >. The grinding support circle is used as the bracket position, the size of the grinding roller surface is required according to the drawing,
the two shaft heads run against the roller surface
.
Five dynamic balance electroplating and fine grinding
Make dynamic balance stage
Seal the ventilation holes, do pressure test without leakage, and do water pressure smooth test. Hard chromium plating, the chromium layer on one side is uniform without pinholes, peeling and other defects. The two shaft heads are finely ground, and the two bearings block the roller surface runout
roughness
. The remaining gears of the shaft head are ground to the tolerance range.
Six frosted and finely ground mirror surfaces
Use a disc grinder to grind the roller surface and inspect the roller surface for water-free corrugated spiral patterns, needle-eye flies, and other imperfections. Go to the polishing machine and polish the roller surface until the roughness reaches
level
to achieve a super mirror surface. Hardness after polishing of chrome plating
.
