Core Components:
Uncoiler and Leveler: Uncoils the metal coil and eliminates curling stress, ensuring a smooth transition into the forming area.
Guide Feeder: Precisely guides the strip into the first set of rolls to prevent deviation.
Main Forming Unit (Core Component): Multiple sets of rolls are arranged in a sequential process sequence to gradually roll the flat sheet into the door frame cross-section.
Inline Punching Unit (Optional): Punches keyholes, hinge holes, or drainage holes simultaneously during the forming process, reducing subsequent steps.
Servo Cutting System: High-precision tracking cutting (flying saw/hydraulic shear), resulting in smooth, burr-free cuts with a length error of ≤±0.5mm.
Automatic Stacker: Stacks or conveys finished door frames, supports counting and packaging.
PLC Control System with Touchscreen Operation: Set parameters (length/speed/quantity), monitor operating status in real time, and perform fault diagnosis.
Industry Application Value:
Replacing Traditional Processes: Replacing manual bending and welding, reducing steps and costs by over 30%.
Improving Consistency: Automated production eliminates human error and ensures interchangeability of large-volume door frames.
Strengthening Structural Performance: Cold work hardening increases profile strength, extending the service life of doors and windows.
