Length tolerance for 6m:L±3mm
punching hole on both WEB side and Height(Flange) side,tolerance: ±1mm,slot hole size:14x25mm or customized hole for similar size
Punching Holes as follows:
Ⅱ. Material:
Material Thickness: 1.5～3.2mm
Applicable material: 340 Mpa for MS or HR and Galvalume 550Mpa AZ150
Ⅲ. Machine Work Flow
Decoiler → Feeding and Leveling Device → Hydrualic Pre-Cutting&Punching Device→Rolling Forming System→Hydraulic Post Cutting →Product Support Frame
IV. Machine Components
1) Hydraulic Decoiler: one set 5 tons
2)Cold Rolling Mill:
With feeding material guide(Automatic feeding control, save labor cost) and leveling device
Body frame made from national standard 450# H type steel by welding;
Wallboard thickness: 30mm(more thicker, more stronger and stable working for long life)
Rollers manufactured from tooling steel Cr12(D3 steel, for long working life), precision machined,
Shafts manufactured from high quality 45# steel, Main Shafts Diameter=ф90mm,straightening roller shaft diameter=ф100mm,precision machined
Motor Driving, chain sprocket transmission,about 22 forming stations(19-step to form and 3 step for final shaping).
Main Motor=22KW,Frequency speed control
Size changing motor：6pcs, Automatically controlled by PLC Programing.
Forming speed approx.18-20m/min (depending on the number of punching holes)
With squareness roller setup
All the screw bolts with grade 8.8 to ensure fix the machine structure tightly and long life during the machine long time running.
3) Hydraulic Punching and Cutting device:
Pre-punching and pre-cutting, use the same hydraulic system
Hydraulic motor: 7.5kw, Hydraulic pressure range: 16Mpa
Punching and Cutting tool material: mold steel Cr12Mov(=D2 steel, with one million times punching/cutting life), Heat treatment to HRC58-62 degree
3-cylinders hole punching system for punching both on web and flange:
provide the Gear setup for UP/Down Action to act with Gear
The base of punching station are on proper lead screw for easy to take the punching stations out for punch and die change, and add the measuring scale for easy adjustment
The hydraulic system with oil filter for the oil filtration,to ensure the circulated oil is clean and lengthen the life of hydraulic system .(See the picture below)
Plus our PATENTED hydraulic UNIVERSAL post-cutting device(NO NEED TO CHANGE cutting die for different size like traditional purlin machine), which make the cut profile looks better
4) PLC Control System
Interchange between C purlin and Z purlin: manually changing with following 3 SIMPLE steps:
But from C75-300 or Z120-300, change size by PLC system automatically: changeover by just press keys on touch screen
Control the quantity and punching, cutting length automatically
Combined with: PLC, Inverter, Touch Screen (big size 7inch for easy operation, both in English and Chinese language), Encoder, etc
Cut-to-length tolerance≤±1 mm
Control Voltage 24V
5) Exit rack:
Un-powered, with rollers on it for east movement,2 units x 3m length
