Auto Change Size C Purlin Machine

Description of roll forming machine for C profile

1. The machine base of adjustable roll forming machine is processed by planning machine and the screw locating pin connects machine stand walls. Straight panels ensure its high accuracy.
2. Hydraulic motor drives main machine’s transmission, which ensures its stability and reliability. It has correct locating and high efficient production.
3. The hydraulic interlaced cutting ensures the exact geometrical profile of formed panel. This cutting method causes no waste material.
4. This adjustable roll forming machine uses computer to measure length. This C purlin has been punched with elliptical holes on two sides and the distance between two holes can be adjusted. The bracing holes are punched in the middle of purlin.
5. Connecting holes for installation are adjustable.
6. Arranges with leveling unit of 7 rollers, which assures the levelness of c purlin.
7. Four chains for transmission and has the chain wheel expanding unit. Sprocket distance is 38.1.
8. Roller materials of adjustable roll forming machine are GCR15.
9. Crafting process of heat treatment: forging-temper-anneal-normalizing-quenching-temper.
