Components description of double layer roll forming machine
Machine body parts
High hardness, high wear resistance and high heat resistance to guarantee long life.
2.High Accuracy Shafts
Solid shafts dia. 72 mm for 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.
3.Rollers of machine
All Rollers manufactured from 45# steel
CNC machines can improve rollers precision.
Chromate finish on surface to add hardness of rollers.
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
Side wall thickness: Q235 with thickness of 20mm
16A-1 Chain and gear move the line, motor drives, about 22-steps stations to form
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.
All processed rollers are assembled on the carpet to avoid scratching on the rollers' surface.
6.Automatic Cutting system
Post to cut, stop to cutting or no-stop cutting for option
All cutting frame are heat treatment to remove the original stress of steel, reduce deformation, improve stability
Cutting tool material: Cr12MoV,hardness can reach 58-60Hrc.
Machine can cut as buyers wanted sheet length,full automatically.
7.Automatic PLC Control System
Control The Quantity And Cutting Length Automatically
Input the production data(such as production quantity,Length,etc.)on the touch screen , machine can finish the set production plan automatically.
One time buyer can set 20 batch data in the programme.
