Processing Specifications and Precision
Processing Dimensions Range
Sheet Length: 700–4000 mm
Sheet Width: 520 mm, 480 mm (corresponding to two pairs of roll specifications)
Precision Requirements
Center Distance Error: ≤±0.5 mm
Diagonal Error: ≤2 mm
Geometric Tolerance: The workpiece shall have no obvious bending after rolling and must be straightened by a straightening machine.
Production Capacity and Power Configuration
Production Efficiency
Adjustable speed, with a maximum capacity of 180 sheets/hour (when the center distance = 2000 mm).
Drive System
Servo Motor Power
7.5 kW
Roll Drive
AC servo motor, speed range 150–1500 revolutions/minute
Lower Roll Control
Hydraulic cylinder lifting or lowering for hydraulic drive.
Equipment Structure and Functions
Rolling Machine Structure
Roll Configuration: One pair of feeding rolls + two pairs of rolling rolls (520 mm and 480 mm specifications, detachable design for easy replacement with other specifications).
Inlet Device: Equipped with rollers and a positioning device, with adjustable positioning width and left-right symmetry to ensure precise feeding.
Automated Control
Control System: Programmable Logic Controller (PLC) + encoder
PLC controls equipment actions, presses, and uncoilers. Processing specifications (sheet length, width, quantity) are input via a touchscreen, supporting multi-specification sequential processing (automatic switching by list).
Encoders precisely control the process length of each part of the workpiece.
Automatic production process: Input parameters → automatic production → automatic shutdown after reaching the specified quantity, requiring no manual intervention.
Material Handling
Post-rolling Treatment: The workpiece is first straightened by a straightening machine, then conveyed by a conveyor to a press, and finally transported to an automatic laminator.
Equipment Features and Advantages
Flexibility
Detachable roll design supports quick switching between producing fins of specifications like 520 mm and 480 mm, adapting to multi-variety needs.
High Precision
The combination of servo motors and encoders ensures critical dimensional accuracy (e.g., center distance, diagonal), meeting precision processing requirements.
High Automation Level
Full-process PLC control supports batch production and multi-specification queued processing, reducing manual operations and improving production efficiency.
Stability
The integration of hydraulic-driven rolls and servo motors ensures smooth operation and reliable workpiece forming quality.
