Product catalog summary
General Overview
The HOERBIGER AKB hydraulic system is engineered for CNC-controlled press brakes, supporting pressing forces up to 2,000 kN. It features a compact control block integrating all necessary valves, excluding suction valves. The system is available with or without a load-sensing module, which improves energy efficiency and minimizes oil heating. The maximum allowable horizontal distance between pressing cylinders is 3,500 mm.
Basic System
The system's core includes a compact block combining control, high retaining, and proportional pressure control valves. Suction valves are located at the cylinder bottom and managed via a 4/2-way spool valve. The system can be equipped with or without a load-sensing regulator.
Options
Optional modules include tool clamping with or without pressure regulation and proportional hydraulic crowning, which can be integrated through the system's interfaces.
Circuit Diagram and Parts List
The document includes a detailed circuit diagram and parts list, highlighting essential components such as proportional pressure control valves, check valves, and pressure switches.
Operating Sequence Diagram
The operating sequence diagram details the hydraulic system's functional flow, ensuring precise positioning and optimal synchronous operation when used with CNC control and a displacement measuring system.
Certification and Compliance
The SAKB hydraulic system adheres to current accident prevention regulations and holds design test certificate No. 98325. Adherence to all installation and operating instructions is necessary for maintaining the certificate's validity.
Additional Information
HOERBIGER provides other hydraulic systems for press brakes, including the IPA, AVB, AMB, and PVM systems. Additional details and a hydraulic system dimensioning calculation program are available on their website.
Important Note
Strict adherence to the assembly instructions and safety precautions provided with the hydraulic press brake systems is essential.
