Hello Everyone.
I have a cold roll forming machine, The width of material is 530 mm with thickness on 1.2 mm mild steel and hardness of around 180 BHN. The finished size required is 520 mm. 24 nos of 6.5 mm depth groves have to be formed. We have a hydraulic arrangement to push the roller vertically down. The diameter of rollers is 252 mm made of OHNS material hardened to 32 HRC. Hydraulic pressure can go upto 150 Tons. The distance between male and female groves is 1.6 mm. Both the male and female rollers have been checked for run out and even high spots have been take care of.
The problem is, when we roll the material we are unable to get the desired depth and also there is a wrinkle formation is the sideways collar of the material.
We would like to get some solution for this problem.
