Components description of double layer roofing panel roll forming machine

Machine's Feature: One machine can make two kinds of profile. Client's profile available. 

1.High Accuracy Shaft

Solid shafts dia. 72mm.

Solid steel shafts are being tooling twice with grinding machine to ensure final precision. Guarantee buyer get high accuracy sheet from Zhongyuan made machine.

3.Design bearings inside forming rollers

Design bearing inside the rollers to make machine run with less loading so that rollers not easy to damage.

Ensure the same speed between the rollers, no speed difference between rollers, improve the forming accuracy.

Bearings are helping to prolong machine life.

4.Main machine body

The main frame of machine is welded separately and the outside wall is connected by screw after being rotoblasted on the surface.

Panting the oil paint to prevent it rust.

Make it smooth on the surface by planer milling machine so that can ensure all the wall plate can be installed in the same level and help to improve machine precision.

Machine frame made from H400 type steel by welding

Side wall thickness: 235Mpa

Main Motor=7.5kw

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 :30m/min. 

5.Automatic Flying Cutting
