Introduction to Trapezoidal Single-Layer Sheet Roll Forming Machine
The trapezoidal single-layer sheet roll forming machine is a specialized equipment used for the continuous processing of metal coils (such as steel sheets, aluminum sheets, etc.). Through multiple sets of rollers, it gradually shapes flat materials into single-layer corrugated sheets with a trapezoidal cross-section. This equipment is widely used in building roofs, wall cladding systems, and other fields. Below is a detailed introduction:
I. Equipment Overview
Function: Processes metal coils (typically 1000-1250 mm wide) into trapezoidal single-layer sheets via roll forming. Common profiles include 840-type, 900-type (numbers indicate effective coverage width in millimeters).
Features: High-efficiency continuous production, precise forming, high automation, and suitability for mass manufacturing.
II. Components and Structure
1. Uncoiler
- Holds and feeds metal coils, equipped with unwinding and alignment systems for smooth material entry.
2. Guiding and Leveling Unit
- Pre-levels coils to eliminate internal stress and prevent warping during forming.
3. Roll Forming Mainframe
- Core Component: Consists of 10-20 sets of precision rollers arranged to progressively bend materials into a trapezoidal profile.
- Rollers are made of alloy steel or surface-hardened materials for wear resistance.
- Each roller set corresponds to a deformation stage, shaping peaks and valleys.
4. Cutting Unit
- Hydraulic or pneumatic shear for automatic cutting at preset lengths (e.g., 6-12 meters).
5. Receiving Table/Stacker
- Collects finished products, often with automated stacking systems for efficiency.
6. Control System
- PLC or CNC systems regulate forming speed, cutting length, and other parameters via a human-machine interface.
III. Working Principle
1. Material Feeding: Coils are uncoiled, leveled, and fed into the roll forming unit.
2. Progressive Forming: Roller sets sequentially bend and shape the material into a trapezoidal cross-section.
3. Length Cutting**: The formed sheet is precisely cut at preset lengths.
4. Output**: Cut sheets are automatically stacked or conveyed to downstream processes.
