More details of major machine components for your reference:
1.Decoiler System
Usage: support steel coil and uncoil it in a turntable way.
Loading capacity: 3 t
Uncoiling width: 500 mm
Inner diameter: 450-550 mm
2.Feeding and Leveling
Make sure inputted steel sheet straight and neat and then roll forming process could be made accurate.
Feeding rollers: 1 set
Guiding rollers: 2 sets
Leveling rollers: 4 up + 5 down
Roller diameter: 80mm
Roller material: Cr15
Power supply: pulled by main transmission motor
3.Main roll forming system
Machine base frame is made of U beam weld steel. In the main roll forming machine, there are 2 buttons for urgency stop in case any accident happens. Machine stations are made of iron cast to make machine stable and strong.
Main motor power (electric motor): 18.5 kw
Table frame: 460 U beam
Roller station: 19 stations
Roller material: Cr15 quench treatment precision machining, hard chrome-plated ,HRC55-60
Shaft diameter:￠80mm
Shaft material: S45C, heat treatment HRC42
Pinching device: 2 Steps of pinching
Transmission: by chain
Roller stand: cast steel structure
Width adjust motors (electric motor): 1.5 kw*1 set, 0.75*2 sets
4.Punching system
Usage: Automatic holes punching controlled by PLC. Punching after forming to make sure the accurate punching. Totally 2 punching stations. For different profile, please change to related dies.
Power supply: hydraulic power
Punching molds: Cr12mov quench treatment Tolerance is ±2 for elements of 12mts
5.Cutting System
It employs post-cutting, hydraulic drive and automatic location to decide the dimension and cut target products, ensure stability, precision and cutting speed.
Cutting type: after forming stop cutting
Power supply: hydraulic power
Material of blade: Cr12mov quench treatment
Length measuring: automatic encoder measuring
Tolerance of length: 3000mm± 1.0mm
For cutting blade, you can manually adjust the cutter to cut different sizes of c z purlin. NO need to change new blade and this cutter is easy to operate.
6.Receiving Table
Frame: weld by angle steel and square tubes, on the top with support rollers.
Table type: no power
Diameter of rollers: 55mm
Table size: 3.0 x 1.0 x 0.9m
Quantity: 2 sets
7.Hydraulic Station
It is controlled by the gear oil pump. After filling the hydraulic oil into the hydraulic oil tank, the hydraulic pump drives the shear to work and empowers the punching operation.
Hydraulic power (electric motor): 11 kw
Hydraulic oil: 46# hydraulic oil
Component: The system consists of a set of hydraulic tanks, two sets of hydraulic pumps, six hydraulic pipes, one set of solenoid valves.
There are wind cooling system on this station.
Electric Control System
