How to Choose CZ Purlin Roll Forming Machine?

The CZ Purlin Roll Forming Machine is a machine that produces purlins. Purlins are a bar or horizontal beams used in supporting structures in a building. The most known purlin machines in the market are C purlin roll forming machine, Z purlin roll forming machine and C/Z interchanging purlin machines. The purlin roll forming exercise is a metal forming exercise that deforms metal under high constraints via a sequence of unique-shaped rolls.
In steel construction, the purlin term means roof framing member spanning parallel to an eave of the building to hold the roof sheeting or decking. Since the wall or rafters hold C purlin, the pre-punched purlin is convenient to install and ideal for both uninsulated and insulated walls and roofs. The height and thickness of a purlin chosen rely on a span load and length.
Structures of Purlin Roll Machine
The main structures of the purlin roll machine work in a non-stop sequence. When the material is inserted into the machine, the machine continuously finds its way via all the stages of the operation. The end of the process produces a final and complete product. The purlin roll machine is designed with forming line, safety protection device, electronic control system, uncoiler, electrical control part, and cutting part.

The primary structure of the purlin roll machine includes:

Roll Forming Line
The roller comprises outstanding Cr12 molds to make eight sets of rollers. With an accuracy of 6 to 7, the precision CNC machine gadget also processes HRC steels amounting to 56 to 6o. With a result of 0.8 roughness, no scratches on top of the produced workpieces.

The forming line takes an integral permanent arch, a hole distance error that embraces less than o.1mm, and a side plate that embraces a 25mm steel plate. The part supporting the production line embraces a high-quality bearing, whereas the bearing embraces roller feed, which can adjust by rotating itself suitable and left, up and down.

The conveying part of the production line, known as the transition system, transmits its power to the gearbox from the motor to the driver wheel via the sprocket. The lower and upper rollers rotate synchronously due to the driving wheel transmitting the steel coil to the forming line front end.

Cutting Part
The cutting part comprises a shearing machine and a fixed-length tool. The fixed-length device controls the length via encoding. The produced C or Z purlin is cut, and the stamping is completed when the purlin reaches a specific length.

Uncoiler is a unique tool used to level line steel plates. It can perform shearing production, levelling, and uncoiling and can also be configured to perform other sheet product production lines. The uncoiler is ideal for industries like vehicles, household
appliances, machinery, metal products, decoration, and steel structure.

The uncoiler part of the purlin forming machine is the gadget responsible for providing sheet materials and storing unwinding materials. It also firmly
delivers the steel coils to the forming production line chamber.

Safety Protection
A protective cover is installed on the primary transmission tool, with many warning signs set up in different places regarding individual safety while in the production line. There are essential safety grounding for electrical equipment, promoting the protection and enhancing individual safety.

Electronic Control System
The purlin production line entirely has a top-notch electronic control system. The electrical control components of the purlin roll machine meet international specifications, and you can also specify your desired parts. The component
requirements include a transparent line number, clear markings, and reasonable parts.

Feeder and Leveling
The roller feeder and leveling structure is the component where the bending process occurs. The deformation of the out of the flat part, plate, or sheet is performed by a series of interchanging bends. The interchanging bends are made by getting the sheet, part, or plate between sets of leveling purlin rollers.

How To Identify The Quality of Purlin Roll Forming Machine?

1. Product Accuracy

When it comes to the quality of a purlin roll forming machine, product accuracy is a core factor. If the product that comes out of this machine is not qualified and lacks precision, then this equipment’s performance is not good.

Therefore, if you find that the product accuracy does not meet the requirements of the drawings, you should figure out whether the roll design is unreasonable or not properly debugged.

No matter what the reason, we should ask the manufacturer to commission the equipment. If the rolls are not designed properly, the machine will cause more trouble in the future after it arrives at your own factory, such as the machine is unstable, easy to waste material and change shape.

2. Roll Quality
In addition to the required precision, the quality of the rolls is also a very important part. If the roll quality is not good, even though product accuracy in the early stage of production can be achieved, once the machine is used for a long time, it will be seriously worn, resulting in the later product accuracy not being up to standard.

Poor quality rolls will even break directly. When a roll is broken, it needs to be reworked, and this process has to go through many processes, such as initial turning, heat treatment, finishing, plating and so on.

At present, CR12 is the best raw material for purlin machine. After heat treatment, the hardness of this material can reach HRC58-60. In Zhongyuan, we process the Cr12 rollers with CNC machine to increase the precision of the rollers. This ensures the wear quality and high precision performance of the rolls.

3. Transmission Mechanism Quality
In a purlin roll forming machine, the most easily worn parts are not only the rolls, but also the transmission mechanism. For example, gears, chains, bearings, etc. If these parts are damaged, they have to be dismantled and replaced, which is time-consuming and laborious, and the machine needs to be re-commissioned once after the replacement. Better choice for purlin machine’s transmission is gear box transmission .

4. Circuit System
The circuit system is also an important factor to note when choosing a purlin roll forming machine. If the equipment has the use of PLC, the PLC program must be backed up. When there is a problem with the PLC, it is much easier to buy the same model to re-import the program.

However, when the program can not be restored, you need to hire a programmer, to write the program and debug it on the spot. Therefore, when we purchase the equipment, we should pay attention to the quality of the circuit components.

5. After-sales Service
No matter how good the product quality is, there should be perfect after-sales service support from the manufacturer, including door-to-door service, technical consultation through network and telephone.

Therefore, when we purchase a purlin roll forming machine, we should choose a reputable manufacturer. To identify the credibility of the manufacturer, you need to check many aspects, such as the size of the factory, the number of staff, reviews on the internet, successful cases, etc.
