Pre Punched Purlin Roll Forming Machine
1. Production Line Overview
This CZ purlin roll forming line is ideal for construction firms and steel structure manufacturers, offering fully automatic CZ profile switching without manual adjustments. It supports 1.5-3mm steel thickness and features flexible pre-punching, allowing precise hole positioning. The line enhances production efficiency, reduces downtime, and ensures high-precision outputs.
2. Profile Description
Profile shape | CZ purlin |
Profile size | Width 80-300mm/Flange 50-100mm |
Profile characteristics | Punching connection holes on the web or flange |
Material type | Galvanized steel |
Material thickness | 1.5-3mm |
CZ purlins are made from galvanized or hot-rolled steel, typically 1.5-3mm thick. They are widely used in steel structure buildings, warehouses, and industrial facilities as roofing and wall supports. These profiles are commonly produced using high-precision roll forming machines with hydraulic punching and cutting systems.
3. Production Process
Decoiler-Guiding & Feeding-Leveler-Pre punch-Roll former-Hydraulic cutting-Out table
A 3T manual decoiler feeds the steel into the guide and leveling unit (integrated with the roll former). The hydraulic pre-punching unit (also integrated) enables adjustable hole positioning before forming. The automatic CZ profile switching system changes the shape and size instantly. Finally, a hydraulic stop-to-cut system ensures precise cutting.
4. Technical Parameters
Decoiler | Power type | Manual, no power. |
Weight capacity | 3 Ton | |
Function | Holds and unwinds the steel coil, supplying material for the forming process. | |
Benefits | Cost-effective, easy to operate, and suitable for small to medium production volumes. | |
Optional type | Hydraulic or electrical decoiler | |
Guiding unit | Type | Guiding rollers |
Function | Aligns the steel strip before entering the forming section, ensuring precise positioning. | |
Design | Adjustable guiding rollers for accommodating different coil widths. | |
Leveler | Type | Integrated Leveler: Built into the roll forming machine instead of being an independent unit. |
Function | Removes coil set and corrects material flatness before forming, ensuring high-precision shaping and uniform hole punching. | |
Necessity | Essential for processing thicker materials (1.5-3mm) to prevent defects like bending, twisting, or misalignment in the final purlin. | |
Hole punching | Position | Pre punch before roll forming |
Power Type | Hydraulic system for stable, high-force punching. | |
Design | Integrated with the forming machine, reducing footprint and enhancing production efficiency. | |
Programmable for adjustable hole distance, adapting to different structural requirements. | ||
Roll former | Speed | 20m/min |
Main power | 15 Kw | |
No. of stations | 14 forming rollers+7 angle rollers | |
Driving system | Chain | |
Frame structure | Cast-iron | |
Shaft diameter | 70-90mm | |
Shaft material | #45 steel quenched 58-62℃ | |
Roller material | High grade #45 steel , surface with hard chrome | |
Function | Gradually shapes the steel strip into the required CZ purlin profile through a series of roller stations. | |
Type | Multi-size adjustable: Supports different purlin dimensions without tool changes. | |
CZ interchangeable: Switches between C and Z purlins automatically without manual | ||
Auto-size change: Adjusts width and flange height through an automated system, improving efficiency and reducing downtime. | ||
Equipment color | Normally blue, customizable | |
Safety cover | Mesh/Enclosed, optional. | |
Cutting unit | Power type | Hydraulic |
Continuity | The roll former stops when cutting. | |
Cutting blade material | Cr12Mov, quenching 58-62℃ | |
Tolerance | ±1mm | |
Control technique | Type | Floor-standing electric control box |
PLC | Siemens | |
Inverter | Yaskawa | |
Frequency changer | Yaskawa | |
Encoder | Yaskawa/OMRON | |
Touch screen | MCGS | |
Electrical parts | Shneider | |
Display language | English/Spanish/Russian/French,etc, customizable | |
Out table | Type | With no power rollers, manual. |
Function | It offers a sturdy support platform. | |
Benefits | Simple structure: The non-powered out table lacks electric or hydraulic systems, reducing complexity and maintenance costs. | |
Lower cost: Without the need for electric drives or additional equipment, the overall cost is lower. | ||
Suitable for small batch production: Ideal when fast, efficient material handling is not required. | ||
Energy-saving: No power system consumption, making it energy-efficient and environmentally friendly. | ||
Optional type | Auto stacker,helping saving labor cost. |
