Description of Roll forming machine

The support frame (raft) is cast (is tempered) and the base frame is welded and stress relieving annealing.
The roll forming machine adopts independent raft structure, and the transmission is the universal shaft.
The guiding device use the quality carbon steel rolls.

The bottom shaft is located by the fixed round holes, the top shaft is located by the sliding way. The support frame (raft) on the transmission side is fixed and the other raft can be take off when assembling the rollers. The removable raft is located by the sliding key on the bottom of the raft, so the location of the rollers can be accurate after every changes of the rollers. All the operation is easy and quick.

The program of the roller’s design is quality and uses imported German COPRA software. It is designed by the computer and has FEA analysis. The roller adopts a combination structure, so the speed difference and roll forming resistance is very little, which can promise the product precision. The material is alloy steel, and quenches totally to increase the hardness, and has polishing treatment on the roller surface.
Material roller: D2 (Cr12MoV), quenching. HRC58-62, hard chromize plating.

The space between top and bottom rollers adjusted by screw shaft, braced by Nut.
