Industrial CZ Purlin Making Machine with Pre Punching & Flying Shear Fully Automatic 80-300mm Standard

Product Overview

The Fully Automatic 80-300mm CZ Purlin Roll Forming Machine is an industrial-grade production line engineered for modern steel structure construction. Equipped with high-speed hydraulic pre-punching and continuous flying shearing technologies, this production line enables automatic size changeover and seamless profile switching between C-purlin and Z-purlin profiles directly via the intelligent PLC touch control system without requiring roller disassembly.

Key Engineering Highlights

• Full Automatic C/Z Profile Changeover: Switch between C-purlin and Z-purlin specifications (80mm to 300mm width) within minutes via PLC touch screen input, completely eliminating tedious manual spacer adjustments.
• High-Speed Flying Cut-off System: Servo-driven flying shear mechanism executes uninterrupted high-precision cutting on the fly, delivering continuous production speeds up to 30 m/min.
• Integrated Hydraulic Pre-Punching: Flexible multi-hole hydraulic pre-punching unit allows programmable punching of web holes and flange holes prior to forming, ensuring burr-free edge precision.
• Heavy-Duty Cr12 Tooling: 20 precision forming stations utilizing vacuum-quenched Cr12 mold steel rollers paired with 45# quenched and tempered solid steel shafts for maximum wear resistance and long-term dimensional stability.
• Intelligent Multi-Voltage Control: Equipped with premium imported PLC and frequency converter, supporting industrial working voltages including 220V, 380V, and 440V.

Technical Specifications

Machine Structure & Production Workflow

The automated CZ purlin manufacturing process follows a streamlined industrial flow designed for high rigidity and continuous material throughput:

• 1. De-coiling & Guiding: Strip steel coil is fed smoothly through adjustable side guide rollers into the entry leveling unit.
• 2. Precision Pre-punching: High-tonnage hydraulic stations punch accurate connection holes and mounting slots according to programmed CAD coordinates.
• 3. Progressive Roll Forming: 20 calibrated roller stations progressively form the web, flanges, and lips into the targeted C or Z cross-section.
• 4. Post-straightening: Dedicated multi-axis straightening rollers eliminate camber, bow, and twisting deviations.
• 5. Synchronized Flying Shearing: High-speed servo tracking cutter sections the purlins precisely without halting the rolling line.
• 6. Automatic Run-out: Finished purlins are received onto heavy-duty discharge racks for bundling.

Applications & Purlin Profiles

Frequently Asked Questions

Q1: How long does it take to switch between C and Z profiles or change sizes?

A: The equipment features an automated motorized size adjustment system controlled via the PLC touchscreen. Profile switching or size adjustments between 80mm and 300mm can be completed automatically within minutes without replacing rollers.

Q2: What is the main advantage of the flying shearing system?

A: Flying shearing cuts the formed purlin synchronously while the material is moving at high speed, avoiding the stop-and-cut cycle of conventional machines, boosting production speed up to 30 m/min and preventing surface marks.

Q3: Can the working voltage be tailored for local industrial power grids?

A: Yes. The drive system and electrical components can be customized to match 220V, 380V, 415V, or 440V, 50Hz/60Hz, 3-phase power according to destination standards.

Q4: What technical support and warranty are provided?

A: The machine is backed by more than 5 years warranty on core components, pre-shipment video outgoing inspection, official machinery test reports, and global remote or on-site engineering support.
