A purlin roll forming machine is a kind of equipment used in the metal processing industry, especially in the production of building materials. It is mainly used to roll and form metal coils into purlins of various specifications and shapes.
Structure of Purlin Roll Forming Machine
Uncoiling Device: It is used to hold and unwind the metal coil, providing a continuous strip of metal material for the subsequent forming process.
Roll Forming Unit: This is the core part of the machine, consisting of multiple pairs of rolls. Each pair of rolls gradually shapes the metal strip into the desired purlin profile through a series of bending and deforming operations.
Cutting Device: Located at the end of the production line, it cuts the continuously formed purlin into the required lengths according to the set size.
Control System: Controls the entire production process, including the speed of the uncoiling device, the rotation speed of the roll forming unit, and the cutting time and length of the cutting device. It usually adopts a programmable logic controller (PLC) to achieve precise control and operation.
Working Principle
The metal coil is first placed on the uncoiling device. The uncoiling device releases the metal strip at a certain speed and sends it into the roll forming unit. In the roll forming unit, the metal strip passes through multiple pairs of rolls. Each pair of rolls has a specific shape and size. As the metal strip moves forward, it is gradually bent and deformed by the rolls until it reaches the final purlin shape. Finally, the cutting device cuts the formed purlin into the specified length, and the finished purlin is discharged.
Types of Purlin Roll Forming Machine
Cold Roll Forming Machine: It forms the metal strip at room temperature. This type of machine is suitable for processing various metal materials and can produce purlins with high precision and good surface quality. It is widely used in the production of light steel purlins.
Hot Roll Forming Machine: It heats the metal material to a certain temperature before forming. This is mainly used for processing some high-strength and difficult-to-form metal materials. The hot roll forming process can reduce the deformation resistance of the material and is conducive to achieving complex purlin shapes.
Applications
Building Industry: Purlins are important components in building structures, especially in steel structure buildings. They are used to support roof panels and wall panels, providing structural support and stability.
Warehouse Construction: In the construction of warehouses, purlin roll forming machines are used to produce purlins that support the large-span roofs and walls of warehouses.
Workshop Buildings: In industrial workshop buildings, purlins produced by such machines play a key role in ensuring the structural integrity of the building and bearing the weight of various components.
