Sigma purline roll forming machine

-
Sigma purline sections are manufactured by cold roll forming pre-hot dipped galvanised steel, grade S450, having a minimum yield stress of 450N/mm2. The top flange of the purlin must have adequate restraint provided by robust steel sheeting (or similar) fixed directly to the top flange.The steel has an external galvanised coating Z275, giving an approximate coating thickness of 20 microns each side. Based on the charactgers of sigma purline, now it is quite popular used in roofing and house building construction area.

Based on the market demand, our factroy developed roll forming machines of making sigma purline. By the roll forming machine, the production could be enhanced greatly.

By the following drawing profile, let us now check what is Sigma purline section?

How the Sigma purline roll forming machine works and how composed?



Working process of Sigma purline roll forming machine:

Decoiling---feeding---leveling---forming---punching---cutting---production

The Sigma purline is composed by the following elemetents:

hydraulic or electrical), leveling system, main roll forming machine, shearing system, PLC control system, hydraulic system and runou table.

Here are some main rolls forming machine parameters:

1).Number of forming steps: 2 steps feeding rollers, 5 steps leveling rollers, 12steps forming rollers,
2).Shaft material: 45# steel, roller material: bearing steel, outer diameter: 80mm 
3).Transport: by chain 
4).Forming speed: 5-12m/min 
5).Motor:18.5kw 
6).Voltage:380v, 50Hz, 3 phases (customized)

Feartures of Sigma purline roll forming machine:

1.It allows you to make range of sigma purline by adjusting spacer by one machine.
2.It either could be pillar type or middle plate. 
3.Best element like PLC, motor to make sure machine could be use long time. 
4.Specail tech knoeledge to make sure accuracy and save electicty energy.
5.Whole life maintance.

Why Sigma purline is used?

Sigma purline could be used either as roofing or house frame, factory building. Here are some pictures for your reference:

Solid Steel Shutter Machine of Rolling Forming for UK-Mode ZTAC11 is specailly designed for the UK market. Steel shutters are used to help prevent unauthorized access and vandalism to premises by adding an extra barrier between "outside" and whatever entrances they may be protecting. When open, the shutters provide an almost unobstructed aperture as the shutter and mechanism store above the doorway and out of the way. Furthermore, the doors are tough and have a long life with little maintenance required.  For the UK-Mode ZTAC11 drawing profile here for your reference:   For the Solid Steel Shutter matched elements like U channel guardrail, and the bottom slat, we also can make for you; in next ariticle I will share more information. Here mainly for the Solid Steel Shutter Machine of Rolling Forming for UK-Mode ZTAC11: Solid Steel Shutter Machine Introduction: 1.Gcr12 Mov roller material, equal to SKD11. Very hard, long time to use.  2.Hydraulic shearing with the ser

Slotted angle machine allows you to make the slotted angle in batch by rolling forming principle. Slotted angle (also sometimes referred to as slotted angle iron) is a system of reusable metal strips used to construct shelving, frames, work benches, equipment stands and other structures. The name derives, first, from the use of elongated slots punched into the metal at uniform intervals to enable assembly of structures fixed with nuts and bolts, and second, from the longitudinal folding of the metal strips to form a right angle. Here are some drawing profile and finished product pictures for your reference: Sample in real: Slotted angle rolling forming machine design: The machine is composed by the following elements: Slotted angle usage: To construct items from slotted angle, items can be cut to size (some versions are marked to show the optimum points at which to cut the metal) using special slotted angle cutters or shears, and then fixed with nuts and bolts. Tension
