China Prestressed Type 2-Roll Round Steel Rod Straightening Machine

An Introduction to Straightening Machine
2-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 & Metrics
Optimized straightening effect, applicable to high strength materials
Pre-set angle of straightening rolls; Hyperbola of top and bottom uneven rolls guarantees linear friction between straightening rolls and rods
Infinite variable speed is adopted to adjust speed steadily.
Cooling lubricating extends working life of straightening rolls
Straightening rolls are installed vertically with greater straightening force and is in favour of maintenance
