305mm C Purlin Forming Machine Component Details
1. Cantilever hydraulic expansion decoiler
The machine adopts cantilever structure. It mainly consists of frame, cantilever hydraulic axis, transmission system, hydraulic system and PLC control system, with the function of loading and unloading coils.
1) Machine frame adopts welded steel sheet with shot blasting treatment.
2) The axis is controlled by selector valve and hydraulic drive system.
2. Coil feeding device
a. Left and right guiding system can be adjusted through screw.
b. The steel sheet is manually fed to the leveling device.
3. Levelling device
3 upper rollers and 4 lower rollers are designed to send the steel strip to the cutting device flatly and straightly.
4. Pre-cutting device
a. The length can be set by the buyer through the control panel. When reaching the set length, the machine will cut the panel automatically.
b. The cutting operation is driven by the power of hydraulic station, ensuring the precision of cutting.
c. Cutter blade: Cr12 mould steel with quenching treatment.
5. Roll forming system
(1) Rollers: bare steel with heat treatment to ensure the hardness of roller reach HRC60.
(2) Roller axis: high grade No. 45 carbon steel to improve the integrated mechanical performance of the shaft.
(3) Specification adjustment: different purlins can be rolled by changing the space of rollers.
(4) Thickness adjustment: the lower rollers are fixed. To adjust the position of upper rollers, change the space of rollers manually by screw. This also applies to sheets with different thicknesses.
6. Electric system
One main motor is equipped to supply power for this C purlin roll forming equipment.
7. Hydraulic station
It supplies power to the cutting device. When it’s not cutting, the station will automatically shutoff to save power.
8. PLC control panel
(1) The electric control system of this machine consists of five parts: operating system, screen, PLC, transducer and electrical parts.
(2) The control system is imported from Mitsubishi.
(3) The system uses modular design and has reasonable and canonical wiring arrangement for easy operation and maintenance.
(4) The independent operating console facilitates the dialogue between the operator and the machine.
(5) Manual or automatic operation mode is available, bringing ease of operation.
9. Runout table
It supports the finished panels. Generally, it can support 2 pieces of 20000mm panels.
