Components description of roll forming machine
1. Guide device
Feeding material guide device, use high speed steel on both sides; its feature of
High hardness, high wear resistance and high heat resistance to guarantee long life of machine.
2. Rollers of machine
All Rollers are made from Cr12MOV.,Hardness 58-60HRC.
CNC machines can improve rollers precision.
Chromate finish on surface to add hardness of rollers.
3. High Accuracy Shafts
Solid shafts dia. 82 or 90mm for different material thickness.
All shafts are tooled twice by cylindrical grinding machine to ensure final precision.
Guarantee buyers get high accuracy deck sheet from Zhongyuan made machine.
4.Design bearings inside forming rollers
Design bearings inside the rollers to allow machine run with less loading so that rollers not easy to damage.
Ensure the same speed between all the rollers, no speed difference between rollers, improve the forming accuracy.
Bearings are helping to prolong machine life. Our made forming machines are allowed using more 15 years.
5. Main machine body
Machine frame made from H450 type steel by welding,planned on surface to guarantee precision
Side wall thickness: 45mm
Motor Driving, Worm gear driving transmission, about 15-steps stations to form
Main Motor=7.5KWx3, Frequency speed control
All the screw bolts with grade 8.8(Some other factories use low grade4.8) to ensure fix the machine structure tightly and long life during the machine long time running.
Forming speed 25-30m/min.
All processed rollers are assembled on the carpet to avoid scratching on the rollers' surface.
