Working Principle Of CZ Steel Equipment

CZ Steel EquipmentThe Core Principle Of (also Known As Purlin Machine) Is Cold Bending Forming: Galvanized/cold-rolled Steel Strip Is Continuously Produced Into C Or Z-shaped Section Profiles Through Unwinding, Leveling, Punching, Multi Pass Rolling, And Fixed Length Cutting.1、 Whole Machine Process (7 Steps)Uncoiling And Feeding: The Steel Coil Is Placed In The Uncoiler And Smoothly Unwinding Is Controlled By A Motor And Tension To Avoid Loosening Or Deviation.Leveling And Straightening: 5-9 Roller Leveling Unit Eliminates The Curling Stress Of Steel Strip And Ensures The Flatness Of The Board Surface.Guided Feeding: The Guide Roller Group Is Positioned To Feed The Steel Strip Into The Forming Machine To Prevent Deviation.Hydraulic Punching (optional): Punch Connection Holes In The Web Or Flange According To The Set Hole Spacing/quantity, And Position Them By PLC Control.Roll Forming (core):8-24 Composition Roller, Arranged According To The Principle Of "gradual Bending".Each Pair Of Rollers Bends Only At A Small Angle, Gradually Pressing The Flat Plate Into A C Or Z Section.The Roller Has Undergone Quenching Treatment, With High Hardness And Wear Resistance, Ensuring Dimensional Accuracy (± 0.5mm).Fixed Length Cutting:Flying Saw Cutting: Moves Synchronously With The Profile For Cutting, With Smooth Cutting Surface And High Precision.Hydraulic Shearing: Simple Structure, Suitable For Thin Materials.Finished Product Discharge: Finished Products Are Collected By The Discharge Rack And Packaged Manually Or By A Palletizer.2、 C/Z Exchange Principle (one Click Exchange Type)Traditional Models: Changing The Model Requires Disassembling And Replacing The Rollers, Which Takes 1-2 Hours.Integrated Machine (mainstream):Roller Position Servo Adjustable (web Height, Flange Width, Curling Edge).PLC Input Parameters (such As C100 × 50 × 20, Z150 × 60 × 20), The Motor Automatically Adjusts The Roller Spacing/angle.The Changeover Time Is ≤ 3 Minutes, And There Is No Need To Change The Roller.3、 Core Control (PLC Fully Automatic)System: PLC+touch Screen, Parameterized Settings (length, Hole Spacing, Quantity, C/Z Specifications).Transmission: The Main Motor (7.5-22kW) Synchronously Drives All Formed Frames Through A Gearbox/universal Shaft.Accuracy: Servo Controlled Feeding+encoder Speed Measurement, Cutting Accuracy ± 1mm, Forming Accuracy ± 0.5mm.4、 Key ParametersRaw Materials: Galvanized Steel Strip (1.0-3.0mm), Q235 Cold-rolled Steel Strip.Molding Speed: 15-30 Meters Per Minute (excluding Punching).Specification Range:C-shaped Steel: Belly Plate 80-300mm, Flange 40-80mm.Z-shaped Steel: Web Plate 120-300mm, Flange 35-80mm.5、 Application And AdvantagesUsage: Steel Structure Factory Purlins, Roof/wall Supports, Photovoltaic Brackets, Storage Shelves.Advantages: Continuous Production, High Efficiency; Cold Bending Process Does Not Damage The Galvanized Layer And Is Corrosion-resistant; Suitable Size, Easy On-site Assembly.
