Forming Angle & Profile Mold Design Guidance
This Purlin Forming Machine adopts multi-stage progressive angle bending for C and Z sectional profiles. Instead of one-time sharp bending, the total bending angle is distributed among multiple forming passes to reduce forming stress and prevent metal cracking, flange warping and scratching of galvanized protective coating. Each roller group is precisely calibrated to adjust flange bending angles and web perpendicularity to meet the unique geometric demands of C and Z purlins. Operators can tune roller gaps and forming angles according to steel coil thickness and tensile strength, compensating for springback and eliminating common defects such as profile twisting and asymmetric flanges. Optimized smooth transition radians ensure consistent dimensional precision during mass production and guarantee smooth bolt assembly for steel buildings and PV mounting frames.
How To Install The C&Z Purlin Former
Site Layout & Foundation Preparation
Prepare a solid and level reinforced concrete foundation with enough operating space for coil loading, profile output and daily maintenance. Reserve the dedicated three-phase power source and hydraulic oil pipeline position in advance. Mark the machine centerline according to layout drawings before equipment arrival.
Unloading, Positioning and Mechanical Alignment
Use forklift or crane to unload each machine section. Place decoiler, forming host, punching station and discharge table sequentially. Adjust the base feet with level gauge to keep the whole line horizontal, align the central line of all forming passes and guide rollers, then fasten anchor bolts.
Electrical & Hydraulic Connection
Wire the control cabinet, servo motors and hydraulic units following the electric schematic diagram. Complete oil filling and pressure testing for the hydraulic system. Check grounding protection and signal communication between HMI, PLC and each drive unit to eliminate circuit faults.
Dry Run, Trial Production & Operator Training
Run the whole line without steel strip to inspect transmission movement and automatic C/Z switching function. Carry out trial forming with raw steel coil, calibrate forming angles, punching and cutting length. Our technicians guide operators to master parameter adjustment and routine troubleshooting.
Package & Delivery
The main forming host, decoiler, punching station and cutting unit will be fixed and packed separately. Key components like rollers, shafts, electrical cabinet are wrapped with waterproof plastic film and packed in wooden cases to prevent moisture and collision during sea transport. The whole machine will be loaded into standard containers. We can arrange FCL or LCL shipment based on order volume. Delivery time depends on machine configuration, normally within 30–45 working days once deposit received.
