50 Series Four-Column Hydraulic Intelligent Precision Leveling Machine

I. Product Overview

The 50 Series Four-Column Hydraulic Intelligent Precision Leveling Machine adopts a four-column body structure, integrating hydraulic drive and intelligent control technology. It is suitable for high-precision leveling of medium-thick metal sheets (0.8-5mm), efficiently correcting warping, wavy deformation, and other deformation problems after stamping and rolling, meeting the stringent flatness requirements of high-end manufacturing fields.

II. Core Advantages
The four-column structure provides high rigidity and uniform force distribution, ensuring stable and deviation-free processing.
The intelligent + hydraulic dual control system achieves a leveling accuracy of ±0.01-0.05mm, far exceeding the standards of conventional equipment.
It is suitable for various medium-thick materials, with a high degree of automation, significantly improving production efficiency.
The rational structural design facilitates convenient maintenance, extends service life, and offers outstanding overall cost-effectiveness.

III. Applicable Applications
·Metal Sheets: High-strength steel plates, alloy plates, hot-rolled plates, large stamped parts, sheet metal structural parts, etc.
·Application Scenarios: Automotive parts manufacturing, engineering machinery processing, precision sheet metal production, machine tool parts processing, ·Aerospace parts assembly, etc. IV. Equipment Performance
·Processing Plate Thickness: 5-16mm
·Number of Leveling Rollers: Multi-roller configuration (standard ≥15 rolls)
·Roller Surface Hardness: HRC62-65 (high wear resistance, impact resistance)
·Hydraulic System Pressure: 1.5-2.5Mpa
·Maximum Processing Width: ≤1800mm (custom widening supported)
·Intelligent Control Accuracy: ±0.01-0.05mm

V. Functional Features
Intelligent Parameter Matching: Automatically adapts leveling parameters according to plate material and thickness, eliminating the need for repeated manual adjustments.
Data Visualization: Equipped with a digital display screen, showing real-time processing pressure, roll gap, and other data, supporting parameter storage and retrieval.
Safety Protection: Equipped with overload protection, emergency stop, plate misalignment detection, and other safety devices.
Flexible Adaptability: Supports fine-tuning of roll gap and can switch between multiple leveling modes to adapt to different processing needs.
