Product Description

Product Description

 

An industrial straightening machine is a metal processing equipment that uses multiple sets of rollers to apply a controlled repetitive bending force to bent and deformed metal materials (plates, bars, tubes, profiles, etc.) to restore them to a flat or straight state to meet accuracy standards.

1. Product Definition and Core Value
Essential Positioning

"Industrial straightening machine is a precision equipment used to eliminate plastic deformation such as bending and twisting of metal materials (plates, bars, pipes, wires, profiles) during rolling, cutting or heat treatment. It improves the straightness/flatness of the material through mechanical correction to meet the dimensional accuracy requirements of subsequent processing or finished products."

Key value: improve product quality, reduce scrap rate, and ensure the continuity of the production line.

2. Core working principle
Mechanical correction principle

"Using a multi-roll staggered arrangement structure, the material is subjected to controllable reverse bending stress by adjusting the roller gap, so that the internal stress distribution of the material exceeds the yield limit, and plastic deformation correction is achieved."
Process: feeding → repeated bending of multi-stage roller system → stress release → straight output.
Roller straightening (mainstream): suitable for plates/strips/bars.
Rotary straightening: dedicated to roundness correction of tubes/round bars.
Stretch straightening: for thin strips or high-precision profiles.

Precision and efficiency

Using finite element analysis (FEA) to optimize the roller layout, the correction accuracy is improved by 40%

Variable frequency speed regulation + fast roller change design, material switching time <15 minutes

Durability design

Working roller surface laser quenching (hardness HRC60+), life span exceeds 100,000 hours

Modular structure design, key components can be quickly replaced

Intelligent innovation

AI algorithm predicts material rebound and automatically compensates roll gap parameters

Remote diagnosis system predicts faults and reduces downtime losses

Core structure and subsystems

Roll system: working roll/support roll (7~29 rolls)
Drive system: variable frequency motor + reducer + gearbox

Drive system: PLC + touch screen + sensor closed loop
Auxiliary system: lubrication cooling/hydraulic station/safety protection
