High-Power Swing Clamp Hydraulic Double Action Model LHE

Product catalog summary

Overview: This document provides comprehensive technical specifications and operational guidelines for high-power pneumatic and hydraulic clamps, including swing clamps, link clamps, and pallet clamps. It covers both pneumatic and hydraulic series, detailing specifications, performance, and operational guidelines.

Specifications: The document outlines specifications for various clamp models, such as the LHE series of high-power hydraulic swing clamps. Key parameters include holding force, lever length, and hydraulic pressure, with formulas provided for calculating holding force.

Performance: Performance curves and tables illustrate the relationship between holding force and lever length at different hydraulic pressures. Maintaining holding force within rated values is emphasized to prevent deformation and ensure longevity.

Procedures and Cautions: Guidelines for manual operation stress the importance of using appropriate hydraulic pressure and lever length to avoid exceeding maximum rated holding force. The document also highlights potential displacement due to lever rigidity and the need for careful design to accommodate reaction forces.

Graphs and Tables: Several graphs and tables depict holding force curves for different models and configurations, aiding in understanding the impact of lever length and hydraulic pressure on holding force.

Recommendations: Recommendations include using meter-out flow control valves for speed adjustment of clamp levers and avoiding excessive swing speeds to prevent damage. Contacting the manufacturer for conditions not covered in the graphs is advised.

Additional Notes: Notes on the differences between holding force and clamping force emphasize considering lever rigidity and reaction forces in design and application.

Installation Procedures: Detailed steps for installing swing clamps include preparing mounting bolts and correctly inserting piping joints, emphasizing specified dimensions to prevent air leakage and ensure proper function.

Options and Accessories: Options such as the gasket option (-C) and quick change lever option (-A) are detailed, including additional components like O-rings and thread plugs.

Performance and Cautions: Performance capabilities of swing clamps, including cylinder force and clamping force, are highlighted. Cautions to prevent contamination and ensure equipment longevity include keeping air vent holes clear and using attachments to prevent coolant and chips from entering.

External Dimensions and Machining: Detailed diagrams and measurements are provided for external dimensions and machining requirements of the mounting area, including thread depths and port positioning for air and lock confirmation.

Notes: Specific installation and operational considerations include not blocking air vent holes and ensuring correct depth of mounting holes.

Overview of Sequence Valves: Detailed information on sequence valves, used to control clamping and positioning sequence of multiple actuators, is provided. The sequence valve operates by allowing pressure flow from the incoming side (P1 port) to the outgoing side (P2 port) once the set pressure is reached.

Specifications and Recommendations: Key specifications include maintaining a pressure difference of at least 1MPa between set and supplying pressures, and ensuring each set pressure differs by 1MPa or more for multiple sequence valves. Hydraulic flow rate adjustments may be necessary depending on the circuit system.

Installation and Operation: Proper hydraulic circuit design is crucial to avoid malfunctions. Air bleeding is necessary, and sequence pressure must be set using a pressure gauge and adjusted with a set screw for anti-rotation. Specific torque values are required for mounting.

Applicable Models and Dimensions: Various models of sequence valves, such as BZS0100, BZS0200, and BZS0300, are listed with corresponding dimensions and machining requirements for mounting areas.

Action Description: The sequence valve activates Actuator ① when hydraulic pressure is on, increasing pressure to the set value, then opens the valve circuit to activate Actuator ②. The process includes locking and releasing actions, with notes on pressure differences and check valve operations.

Additional Notes: Ensure no cutting chips or burrs are present in machining hole tolerance parts, and use the sequence pressure adjusting hex within the specified range to avoid disassembly of internal components.
