ZTRFM Roofing Sheet Machine: Precision and Efficiency in Manufacturing
In the manufacturing industry, achieving high precision and operational efficiency is crucial for production success.
Precise Shearing Capabilities
- Feeding Device: Upgraded with a steel plate support and two guide wheel sets, it securely holds materials. The manual roller adjustment allows for fine-tuning, ensuring accurate positioning and reducing material waste.
- Pre-cutting Shear: Trims materials before forming, optimizing material usage and cutting costs.
- Hydraulic Cutting Shear: Controlled by four guide post cylinders, it uses hydraulic force and high-precision, thickened blades to deliver clean, burr-free cuts.
- Length Measurement System: An encoder in the shearing section, paired with a tension spring, provides accurate length data. The PLC system uses this information to control the roll former, ensuring coils are cut to the required length.
- Additional Features: The front roller shear, rear shear, and PLC system work in tandem to streamline production. A standard manual broach on the roller shear enables precise straight cutting, while rubber pinch rollers prevent slippage during feeding.
Reliable Forming Performance
The forming section is built for demanding tasks:
- Bolt Fixing: 8.8mm grade high-strength bolts secure key components, offering enhanced tensile strength and fatigue resistance. This ensures stability during operation and precision in profile formation.
- Forming Shaft: The 80 mm thick alloy steel shaft withstands significant extrusion force and torque, suitable for various materials and minimizing the risk of bending under heavy loads.
- Machine Base: Constructed from 350H steel and reinforced with diagonal braces, the base provides a robust foundation, resisting compression, bending, and vibrations during heavy-duty production.
- Surface Coating: A high-precision, fine spray painting with a thickened coating protects the machine from rust and corrosion, extending its service life and reducing maintenance needs.
