Detailed Manufacturing Process of the Machine Itself

The construction of a **Full Auto C Z purlin Roll forming machine** is a testament to precision engineering. The quality and lifespan of the machine are heavily dependent on the materials and manufacturing processes employed:

1. Frame Construction: The machine base and frame are typically constructed from high-strength structural steel, often welded using advanced techniques to ensure rigidity and stability, crucial for vibration reduction and maintaining alignment during high-speed operation.
2. Roller Manufacturing (Critical Component):
   • Material Selection: Rollers, which are the heart of the forming process, are usually made from premium tool steels such as Cr12MoV or GCr15 (equivalent to AISI D2 or 52100 bearing steel). These materials are chosen for their exceptional wear resistance and toughness.
   • Precision Machining: The profiles of the rollers are precisely machined using high-accuracy CNC machining centers. This ensures that each roller profile matches the exact design specifications, allowing for a smooth and accurate forming process. Tolerances are often within microns (e.001mm) to guarantee seamless material flow and consistent purlin quality.
   • Heat Treatment: Post-machining, the rollers undergo rigorous heat treatment processes, including quenching and tempering. This process hardens the steel to achieve a surface hardness of HRC 58-62, significantly extending the rollers' operational life and preventing premature wear, even under continuous heavy loads.
   • Surface Finishing: Some rollers may undergo additional surface treatments like hard chrome plating or nitriding to further enhance wear resistance and reduce friction, improving both the quality of the formed purlin and the efficiency of the machine.
3. Shaft and Bearing Assembly: The shafts supporting the rollers are typically made from high-grade 45# carbon steel (equivalent to AISI 1045), precision ground and heat-treated for optimal strength and concentricity. High-quality bearings (e.g., SKF, FAG equivalents) are used to ensure smooth rotation and minimize friction, contributing to energy efficiency and machine longevity.
4. Cutting Die Manufacturing: The hydraulic cutting dies, responsible for shearing the formed purlins to length, are also made from high-strength, wear-resistant tool steel. They are precisely ground and heat-treated to ensure clean, burr-free cuts and extended service life.
5. Assembly and Alignment: The entire machine is assembled in a controlled environment. Critical alignment checks are performed using laser alignment tools and precision gauges to ensure that all forming stations are perfectly aligned, which is vital for producing straight and accurate purlin profiles.
6. Electrical and Control System Integration: High-quality electrical components from reputable brands (e.g., Siemens, Schneider Electric, Panasonic) are integrated. The PLC is programmed with sophisticated algorithms to manage the entire process, from decoiling speed to cutting length and automatic profile changes.

Process Flow of Purlin Production

The manufacturing process of C and Z purlins using a **Full Auto C Z purlin Roll forming machine** follows a streamlined, highly automated sequence:

1. Decoiling: The process begins with loading a large coil of steel (typically galvanized or pre-painted) onto an uncoiler (decoiler). The uncoiler feeds the flat steel strip into the machine. Modern decoilers are often hydraulic, with automatic tension control to ensure smooth and consistent material flow.
2. Guiding and Leveling: Before forming, the steel strip passes through a guiding mechanism and sometimes a leveling device to ensure it enters the roll former straight and flat, removing any coil set or minor imperfections.
3. Punching/Pre-punching (Optional): If required, holes for bolts or fasteners are pre-punched into the flat strip before forming. This is often done by a hydraulic punching unit integrated into the line. Pre-punching ensures precise hole placement regardless of the final purlin length and avoids deformation that can occur with post-punching on a formed profile.
4. Roll Forming: This is the core of the process. The flat steel strip is progressively shaped by passing through a series of precisely designed roller dies. Each station incrementally bends the metal closer to the desired C or Z profile. The number of stations (typically 16-20) ensures a gradual forming process, minimizing stress on the material and preserving its structural integrity and surface finish.
5. Automatic Size and Profile Change (Key Automation Feature): A distinguishing feature of a **Full Auto C Z purlin Roll forming machine** is its ability to automatically change between C and Z profiles and adjust dimensions (web height, flange width, lip height) without manual intervention. This is achieved through a sophisticated hydraulic and servo-motor system controlled by the PLC, which adjusts the position of the roller shafts and forming tools in minutes, significantly reducing downtime compared to older, manual adjustment machines.
6. Cutting: Once the purlin reaches the desired length, it is automatically cut by a hydraulic shearing device. For high-speed production, a "flying shear" mechanism is used, which cuts the purlin while it is still moving, ensuring continuous production without stopping the roll former.
7. Output and Stacking: The finished purlins are then conveyed to an output table or an automatic stacking system, ready for packaging, storage, or immediate use.
