Two Roller Type Round Black Steel Bar Straightening Machine
with High
EfficiencyAn Introduction to Straightening Machine2-roll
straightening machine is mainly used to straighten bended and
distorted metal rods or pipes with guaranteed wall thickness with
high efficiency. It can process both nonferrous metal or non-metal
rod materials. 2-roll straightening machine and peeling machine can
be combined to be a connected unit. If straightness of raw
materials is above 1.5mm/m, pre-straightening shall be used before
peeling.There are 3 structures of 2-roll straightening machine :
two-beam and four-column, pre-stressed type and frame type. After
straightening, straightness of finished products can achieve
0.25~0.4mm/m. Surface roughness is less than 1 μm. The
transportation devices have both manual and automatic
types.Strengths & MetricsOptimized straightening effect, applicable
to high strength materialsPre-set angle of straightening rolls;
Hyperbola of top and bottom uneven rolls guarantees linear friction
between straightening rolls and rodsInfinite variable speed is
adopted to adjust speed steadily.Cooling lubricating extends
working life of straightening rollsStraightening rolls are
installed vertically with greater straightening force and is in
favour of maintenanceParameter tableModelJY80ZWorkpiece
