Many steel structure processing plants encounter these problems when producing C/Z purlins:
✅ Changing between C and Z purlin models is cumbersome, resulting in significant downtime.
✅ Adjusting purlin width requires repeated manual disassembly and reassembly of rollers, leading to long debugging cycles.
✅ Poor roller material causes rapid wear at high speeds, resulting in frequent maintenance and reduced production capacity.
✅ Poor straightness of the production line leads to twisted and non-standard curvature in finished products, resulting in a high defect rate.
✅ Limited punching specifications cannot accommodate orders with multiple hole diameters, limiting business.
✅ Outdated control system results in poor length cutting accuracy and significant material waste.
This fully automatic C/Z interchangeable purlin cold bending forming production line specifically addresses these industry pain points:
🔹 18-unit forming frame with 180° module rotation for switching between C and Z purlins, eliminating the need for complete disassembly and reassembly.
🔹 One-button size adjustment via electronic control, eliminating the need for repeated roller disassembly and significantly reducing downtime.
🔹 The rolls are made of GCr15 bearing steel with a heat treatment hardness of HRC58-60, ensuring wear resistance and a longer service life; the main shaft is 42CrMo heat-treated for stable operation.
🔹 Multiple leveling structures ensure high flatness of the formed sheet metal, resulting in aesthetically pleasing finished products and reduced scrap.
🔹 Integrated dual-station punching mechanism, compatible with various specifications of round and elliptical holes, adaptable to diverse orders.
🔹 PLC touchscreen complete electrical control system, fixed-length hydraulic cutting, ensuring stable dimensional accuracy.
🔹 Production line speed up to 30 meters/minute, adaptable to 1.5–3.6mm steel strip, covering all specifications of 80–320mm C/Z purlins.
One-stop service from uncoiling → leveling → cold bending → punching → fixed-length cutting → discharge, one production line handles both C and Z purlins, helping factories reduce equipment investment and improve production efficiency!
