With the change of building structure, three Air duct production line and five Air duct production lineare the equipment that can be lacked in large buildings now. Whether it is large factory or kitchen ventilation, or central air conditioning installation, these equipment can not be separated from air ducts in the installation process. We also often see some terms including five lines of the production duct production line, three lines of the duct production line and so on…. So what is the five lines and three lines of air duct production? What do different types of production lines mean? Today, Fengli machinery and you say about the small knowledge of the air duct production line.
The types of air duct production lines on the market mainly include first line, second line, third line, fourth line, fifth line and so on. The overall difference between these five production lines is not very great, only in the details. Before we talk about the differences between the five production lines, we need to know how a complete air duct production line works first, so that we can better understand the differences between the types of production lines.
A complete duct production line should achieve the following functions.
1. Rolling material selection and blanking function: 2-6 kinds of rolling material with different thickness or material can be selected;
2. Pressing and flattening function: This function is to adjust the process before the processing of roll material to prevent waste;
3. Punching, chamfering, grooving functions: This function can complete the production of air duct installation holes, avoid the inconvenience caused by later punching;
4. Cut off function: This function will be removed from the sheet material, the next step of processing;
5. Transmission function; Convenient winding material automatic processing of the next process;
6. Bite: This function can realize the pressing operation of sheet material and make joint Angle;
7. Common plate flange forming; This function is the key step of making double-sided common plate flange;
8. Bending molding: This is the last procedure, and the air duct has been formed after this procedure.
After understanding the production steps of the air duct, we began to understand the differences between five production lines, mainly as follows: the production line of the air duct, the biggest difference is that there is no punching tip and punching square mouth oil press; Second line of air duct production, mainly can not be folded into shape, the last process is shear cutting; The last process of the three lines of air duct production is rectangular duct folding, without common plate flange; Four lines of air duct production, common plate flange molding, but not common plate flange air duct folding square shape; Five lines of air duct production, common plate flange air duct molding, a high degree of automation.
