Hydraulic System
The hydraulic system consists of a hydraulic pump, valve group, and auxilizry components, using a compact design for easy maintenance and low leakage. The system features pressure regulation, synchroniaztion, and speed control.
Pressure Regulation & Protection
Pressure is adjusted by a main relief valve, with a system pressure of 19.5 MPa. Overflow valves provide pressure protection for the lower and side rolls.
Synchronized Movement
High-precision displacement sensors ensure the synchronized operation of the rolls, with pressure sensors maintaining accurate synchronization.
Compact & Efficient Design
The hydraulic station is mounted on the base, saving space and simplifying transportation for maximum operational efficiency.
Drive System
A dual-drive transmission powers the hydraulic upper roll. Two cylinders lift the lower roll, while friction-driven side rolls utilize displacement sensors to ensure high synchronization and precise control.
Main Frame
The stress-relieved welded steel frame ensures high strength and stability. This durable, anti-deformative design minimizes vibration, extending service life for demanding heavy-duty bending applications.
CNC Controller
The four-roll plate rolling machine features an upper roll and two lower rolls. The upper roll adjusts vertically for pressure application, while the lower rolls are fixed in position to provide support and drive the plate. Together, they enable precise metal bending with consistent alignment, high durability, and smooth operation, meeting diverse industrial needs.
● Two Operation Modes: The system offers both handheld and console controls for flexible operation.
● Automatic Positioning: Remembers and automatically returns to previous roll positions, improving efficiency.
● Online Parameter Modification: Users can modify parameters to meet specific needs, with easy maintenance of parts like encoders.
● Real-time Monitoring: The system monitors and limits incorrect actions, providing timely alerts to ensure safety.
● Synchronization Control: Ensures synchronized lifting, independent lifting, or simultaneous tilting for efficient bending.
● Braking System: Reduces rotational inertia and improves movement precision during frequent starts and stops.
● Comprehensive Protection: Includes overload, short circuit, under voltage, and phase loss protections to prevent system failures.
Security Fence*
The safety fence on the four-roll plate rolling machine protects operators by preventing unauthorized access to the working area. It features safety switches that automatically stop the machine if the fence is opened, ensuring worker safety during operation.

Support System*
The support system of the four-all plate rolling machine enhances stability and precision during the rolling process, especially when handing large or thin plates. It typically includes side support and upper support, each designed to address specific challenges.
Side Support →
Side supports stabilize thin plates, ensuring alignment and rolling precision.
Vertical Support →
Upper support stabilizes large plates for accurate, complex rolling.
Why HARSLE
General FAQs
Look at factors like material thickness, roll diameter, bending precision, and whether you need a 2, 3, or 4-roll machine depending on the application.
2-roll machines are ideal for lighter bending, while 3-roll and 4-roll machines provide greater control and are suitable for thicker materials and more complex shapes.
Follow the machine’s manual for setup, use proper safety gear, and ensure that hands and tools are clear of the rollers during operation. HARSLE’s machines come with built-in safety features for added protection.
