Double-Linkage Press Brake: Affordable and Flexible Alternative to Large-Tonnage Machines

Companies often face high cost pressures when purchasing sheet metal bending machines. The initial price of a single large-tonnage bending machine is extremely high, along with high transportation costs and complex installation requirements. These large machines often need special infrastructure, such as excavating the base, which further increases costs.

The double linkage bending machine system offers a cost-effective solution. Two standard bending machines work together to achieve the same bending capabilities as a single large-tonnage machine, significantly reducing procurement and installation costs for companies.

Double Machine Linkage Technology: High-precision Tandem Press Brake

Optimized For Bending Extra-long Workpieces – High Speed And Strong Output Force – Intelligent Control

In order to improve the processing efficiency of extra-long workpieces, ERSM proudly launches the EHP series of double machine linkage hybrid servo bending machines. A single bending can complete the forming of large-sized sheet metal parts, reducing secondary operations and improving production cycles.

Why Choose a Double-Linkage Press Brake System Over a Single Large-Tonnage Machine?

Cost Savings: Two standard machines are far more affordable than one large press brake, helping businesses reduce their initial investment.

Flexibility: The two machines can be operated separately or linked together for high-tonnage jobs, offering versatility based on production needs.

Lower Transportation Costs: Standard press brakes are easier and cheaper to transport, unlike large-tonnage machines that require special handling and larger logistics.

Reduced Installation Costs: Unlike heavy-duty machines that require custom foundations, standard press brakes can be installed on conventional flooring, eliminating the need for costly ground preparation.

Increased Efficiency: You can optimize production by using one machine for smaller tasks and both machines in unison for large, complex bending projects.

Free connection in series, flexible combination, and infinite bending possibilities!

Includes the Following Features and Configurations

High Rigidity Frame

The machine bed and moving tool holder and other key parts are welded with steel plates, which have good rigidity, high strength and good anti-distortion and deformation ability.
The frame and upper working slide are processed by imported large-scale CNC floor boring and milling precision mother machines, ensuring the position requirements of each installation surface.
In order to ensure the overall accuracy of the machine tool is long-lasting and stable, the bed is eliminated through high-temperature annealing, surface shot peening and other processes to eliminate internal stress.

Cantilever Operating System

The cantilever operating system follows the ergonomic design, making operation easier and more convenient, effectively improving work efficiency.
Equipped with a movable foot control switch to further enhance the safety and reliability of operation.
The electrical wiring of the equipment has been scientifically optimized to facilitate maintenance and fault diagnosis, ensuring stable operation of the equipment and long-lasting and reliable performance.

Controller

The CybTouch 12/15PS CNC system uses advanced bending algorithms and industrial-grade chips that automatically calculate bending angles, main pressure and deflection compensation, has an “EasyBend” easy bending function and a user-friendly human-machine interface.
Its advanced design includes a 15-inch LCD touch screen that provides an intuitive interface and can be used while wearing gloves.
Fully efficient bending programming meets the needs of mass production processing, achieving efficient processing and simplifying operations processing.

Synchronous Control Device

The spindle power box uses heavy-duty ball screws and bearings for durability, with sealed protection to prevent dust damage.
A dual grating ruler system enhances synchronization and stability, while feedback control ensures precise positioning, improving accuracy and reliability.

Backgauge

The back gauge adopts the latest Belgian design, precise and stable back gauge, and the servo motor drives the ball screw, which has the characteristics of fast speed and high positioning accuracy.
The novel and unique double linear guide structure ensures excellent positioning accuracy.
Multi-stage gear design, increased positioning range, value for money.
Modular design, the number of control axes can be selected from single axis X to multiple axes.
During the bending process, the back gauge automatically avoids collision with the workpiece.

Fast Clamp

The upper die is installed on the slide and fixed by a heavy-duty clamping device. The lower die adopts a square die form, which is convenient and quick to change the die, reduces labor intensity and improves production efficiency.
The bending tool is fully quenched, durable, high precision, and reduces the correction steps and processing costs. The fully quenched die has higher durability than the standard die.

The dual servo oil-electric hybrid system, developed with Ruitie’s patented control, manages the rapid descent, bending, and return of Y1 and Y2 using servo motors and pumps on both sides. This results in fast, stable action, with response speeds significantly faster than proportional valve control.
The throat deformation compensation device features grating rulers on both sides of the machine tool. These rulers, connected to the workbench via a C-type frame, effectively minimize the impact of throat deformation on the slider’s position.
The UBB large-tonnage system CNC bending machine utilizes a CNC mechanical convex wedge deflection compensation workbench. Multiple sets of inclined convex wedges within the workbench move relative to one another, ensuring superior bending accuracy.
A floating spherical support hinge structure is used for the cylinder piston rod and slider. This allows the slider to tilt up to 2.5 degrees without affecting machine accuracy.
The connection between the cylinder and the frame employs a stepped surface force, ensuring that the wedge iron eliminates gaps between force-bearing surfaces. The bolts are tightened to handle tension, not shear force.
The rack side panels are connected by stepped surface support and bolts, ensuring high safety as the bolts only handle tension, not shear force.
