When selecting a purlin roll forming machine, what should be done to identify the quality of the machine? This may be a headache for many beginners. But it is also an important one.
If you do not consider carefully when buying a purlin roll forming machine, many troubles will occur in future production, causing loss of money or, worse, forcing the project to stop.
Don't worry, this blog will guide you step by step on how to identify the quality of a CZ purlin roll forming machine like an expert.
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.
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.
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 .
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.
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.
