Metal Sheet Glazed Tile Roll Forming Machine
The Metal Sheet Glazed Tile Roll Forming Machine is a highly automated, continuous production specialized equipment. Its primary function is to process metal coils (such as aluminum-zinc alloy coated steel, color-coated steel, aluminum alloy sheets, etc.) into metal roofing tiles with the shape and decorative effect of traditional glazed tiles, using the cold roll forming process.
Here is a detailed introduction to this equipment:
1. Core Principle (Roll Forming):
The technology is based on the cold roll forming process.
The metal coil is uncoiled, leveled, and then continuously fed into the forming mainframe.
The forming mainframe consists of multiple pairs (often a dozen or more) of precisely designed forming rolls arranged in sequence. Each pair of rolls imparts a specific bending action on the passing metal sheet.
The metal sheet progressively passes through these roll sets, undergoing step-by-step, continuous bending deformation, ultimately forming the precise cross-sectional shape of a glazed tile (including structures like corrugations, peaks, valleys, drip edges, and overlapping edges).
2. Main Equipment Components:
Uncoiler (Pay-off Reel): Holds the metal coil and controls stable unwinding and tension.
Feed Guide Device: Guides the coil smoothly into subsequent equipment.
Leveling Machine: Eliminates the coil's inherent internal stress, curl, and warpage, ensuring flat material enters the forming machine, which is crucial for final forming quality.
Forming Mainframe (Core Component):
Contains multiple sets of precision-machined forming rolls (roll wheels).
Each roll set completes one or more specific bending steps.
Rolls are typically made of high-strength alloy steel (e.g., Cr12MoV), heat-treated and precision-ground for high hardness, wear resistance, and surface finish.
Roll sets are mounted on a high-rigidity, high-precision frame to ensure stable forming.
Cutting Device: Precisely cuts the continuously formed tile to the set length after forming. Common methods include hydraulic shearing, flying cut-off saws, or servo tracking cut-off.
Outlet Conveyor/Receiving Table: Receives the cut finished tiles and stacks them neatly or conveys them to a designated location.
Electrical Control System: Typically uses a PLC (Programmable Logic Controller) and touchscreen HMI (Human-Machine Interface) to control the speed, length, cutting action, tension, etc., of the entire production line, enabling automated operation and parameter setting. Advanced equipment may feature servo systems for more precise control.
(Optional) Online Embossing Unit: Rolls decorative patterns (like antique textures, wood grain, stone grain) onto the tile surface during or after forming, enhancing aesthetics and the antique effect.
(Optional) Automatic Stacking System: Automatically stacks finished tiles neatly and bundles them.
3. Processable Materials:
Aluminum-Zinc Alloy Coated Steel (AZ, Galvalume): Most commonly used, excellent corrosion resistance.
Color Coated Steel (PPGI, PPGL) Coated with colored organic coatings (polyester, siliconized polyester, PVDF, etc.) on a galvanized or galvalume substrate, offering rich color choices and additional corrosion/weather resistance.
Galvanized Steel (GI): Economical and practical.
Aluminum Alloy Sheet: Lightweight, corrosion-resistant, often used for special requirements.
Stainless Steel Sheet: High corrosion resistance, higher cost.
Common Thickness: Usually 0.3mm - 0.8mm.
