I. Product Overview

The Z-Purlin Roll Forming Machine is a professional cold roll forming equipment specifically designed for steel structure buildings, photovoltaic (PV) mounting systems, industrial plants, and other related applications. The equipment utilizes a multi-stand continuous roll forming process to transform metal coils (such as galvanized steel, Zn-Al-Mg coated steel, and cold-rolled steel) into high-precision, high-strength, and uniform Z-section purlins in a single pass. It offers high forming efficiency, precise dimensional control, and meets the production needs of both large-scale standardized and customized purlins.

II. Core Technologies and Structural Features

1. 1.

   High-Stiffness Frame Design

   • Constructed with a fully welded heavy-duty steel plate structure, stress-relieved to ensure vibration-free and deformation-free operation at high speeds.

   • The forming stands feature an adjustable design, facilitating rapid adjustment of roller clearances and simplifying maintenance.

   
   

2. 2.

   Precision Forming System

   • Forming rollers are forged from Cr12MoV alloy steel, undergo CNC machining, heat treatment, and hard chrome plating, achieving a hardness of HRC 58-62 for exceptional wear resistance.

   • Each roller shaft is equipped with an independent micro-adjustment device, enabling precision adjustments within ±0.1mm to ensure consistent cross-sectional dimensions.

   
   

3. 3.

   Intelligent Control System

   • Employs a PLC combined with a touchscreen HMI, supporting storage and one-touch recall of multiple parameter sets.

   • Integrated functions include automatic length measurement, fixed-length cutting, production counting, fault diagnosis, and data traceability.

   • An optional remote monitoring module enables cloud-based management of production data.

   
   

4. 4.

   High-Efficiency Drive System

   • Utilizes a gearbox with hardened helical gear transmission, paired with universal joints, achieving transmission efficiency of ≥95% and operating noise ≤75dB.

   • The main motor is equipped with a variable frequency drive, supporting stepless speed adjustment from 0-25 m/min to accommodate different material thicknesses and forming speed requirements.

   
   

5. 5.

   Modular Functional Expansion

   • Flexible options include an automatic loading and decoiling system, hydraulic or servo cut-to-length system, online punching device, and automatic stacking mechanism, enabling the configuration of a fully automated production line.
