Components description of roof sheet roll forming machine

Machine body parts

1.High Accuracy Shafts

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.


2.Rollers of machine

Each forming roller use CNC machine to polish and machining into designed rollers shape,it can improve rollers accuracy.And planted 0.03-0.05mm hard chrome to make sure machine running more than 15years+ for you.


3.Main machine body

Machine frame made from H350 type steel by welding,planned on surface to guarantee precision.

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. Side wall thickness: 40mm

4.Automatic Cutting system

Adopts post cutting, Stop to cut;

2)  The cutting blade material is Cr12mov with quenched treatment.

2)  Adopts welded frame for good rigidity.

4)  Cutting frame has been heat treatment to avoid final product deformation. cutting length tolerance ±1.5mm.

5)  The power of cutting is provided by electrical power. 3KW.

6)  The final product can be cut as per set length in PLC controller, and the length is automatically measured by encoder. When final product reaches the set length, machine will stop to cut the product automatically. Finish this action, machine will run again continuously.

5.PLC Control System:

1) This system uses Mitsubishi PLC to control the all working actions. Production quantity and each piece length will be automatically measured. It is convenient to control the roll forming machine.

2) Mitsubishi converter adjusts speed technology, realize the automatic production.

3)  Touch screen is input and canceled the working data.

4)  Friendly man-machine interface system can be set batches to the workpiece, length, quantity, etc.

5)  Encoder count, having function of count and measuring length.

6)  Suitable power voltage: 380V/50HZ/3Phase (can be custom by client’s requirement).
