Product Description Leveling and Cutting Machine Introduction A leveling and cutting machine is an integrated automated system that combines **metal sheet leveling (straightening)** and **fixed-length cutting**. It primarily processes defects in uncoiled metal strips (e.g., steel/aluminum coils), such as edge waves, warping, and camber, then cuts them into flat sheets of precise lengths. Core Functions & Working Principles: 1. Leveling (Straightening): Purpose:Eliminates internal stresses from rolling/coiling/uncoiling processes. Principle: Sheets pass through staggered upper/lower leveling rollers. These rollers apply reverse bending stress (like flattening crumpled paper), inducing plastic deformation to permanently remove stress irregularities. Key: Effectiveness depends on roller count, diameter, arrangement, and pressure. Thin sheets (≤3mm) require more rollers (17+); thick sheets (≥3mm) use fewer rollers (9-11) with higher pressure. 2. Cutting: Purpose: Precisely cuts leveled sheets to preset lengths. Principle: Servo-driven feed rollers with encoders advance sheets. Cutting activates when reaching target length. Cutting Methods: Hydraulic Shear: For thick plates (≥2mm)/high-strength steel. High cutting force, stable. Pneumatic Punching: For thin sheets (≤3mm)/high-speed lines. Burr-free cuts, efficient. Laser Cutting (Optional): For complex contours/high precision. No tooling changes. Key Components: Uncoiler (Optional): Holds/unwinds metal coils. Feeding Guide: Directs sheets into leveling section. Leveling Unit: Core assembly with hardened alloy-steel rollers. Adjustable upper/lower rollers adapt to sheet thickness. Feeding Mechanism: Servo-driven feed rollers + encoder for micron-level accuracy. Cutting Unit: Hydraulic/pneumatic/laser cutter with material clamps. Discharge Table: Collects finished sheets. Control System: PLC + HMI touchscreen. Stores cutting parameters (length/quantity), enables auto-operation, and diagnostics. Advantages & Applications: Advantages: Integrated process → Saves space/costs, boosts efficiency. High precision: Cutting tolerance ±0.3mm; flatness ≤0.5mm/m2. Quality assurance: Eliminates defects for downstream processes (e.g., roll forming). Automation: Reduces labor, enables continuous production. Material savings: Precise cuts minimize waste. Applications: Roll forming lines (U/C channels, roofing panels). Sheet metal fabrication (cabinets, ducts). Construction (wall/roof base sheets). Automotive/appliance component preprocessing.
