Door Frame Roll Forming Machine

Description

Door frame roll forming machine is designed to roll the cold rolled galvanized sheets with the thickness from 0.4 mm to 1.5 mm. This cold roll forming line consists of hydraulic uncoiler, leveler, servo feeder, punching device, roll forming unit, fly shearing, run-out table, hydraulic station and electric control cabinet. The hydraulic station of Rontech door frame roll forming machine adopts accumulator and PLC controller to generate a fast punching and shearing speed. When this cold roll forming line runs automatically, the maximum speed can reach up to 20 m/min with a stable and reliable performance. Door frame roll forming machine is equipped with a double cantilever rack that is beneficial to improve the efficiency when changing steel coils.
