Hydraulic/Pneumatic Actuator for Electrode Holding

Product Specifications

Technical details and manufacturing context for Hydraulic/Pneumatic Actuator

Definition

This hydraulic/pneumatic actuator is a component used in electrode holding mechanisms within machinery and equipment manufacturing. It converts fluid pressure—either hydraulic oil or compressed air—into controlled mechanical force and motion, enabling precise positioning, clamping, and adjustment of electrodes during production processes. The actuator ensures accurate electrode alignment and secure holding, contributing to consistent manufacturing quality. Operating pressure ranges from 1.0 to 1.6 MPa, with a note that Stroke length is available from 50 to 500 mm, with custom lengths on request. Thrust force at rated pressure spans 500 to 5000 N. Positioning accuracy is ±0.05 mm with closed-loop control. Operating temperature for standard seals is -20 to 80 °C. Ingress protection is rated IP65 to IP68 (IEC 60529), with IP68 suitable for submersion. Supply voltage for positioner/feedback is 24 V DC ±10%. Body material is 316L stainless steel (ASTM A240), corrosion resistant. Weight ranges from 5 to 50 kg, depending on size. Materials used include stainless steel, aluminum alloy, engineering plastics, and sealing elastomers. The actuator is designed for integration into electrode holding systems, where it provides the necessary force and movement for reliable operation. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before procurement, as the listed parameters are reference ranges and may vary by configuration. The actuator is not a standalone product but a component that requires proper selection based on application requirements, including pressure, stroke, force, and environmental conditions.

Working Principle

The actuator operates by converting fluid pressure into mechanical force. Hydraulic oil or compressed air enters a chamber, acting on a piston, diaphragm, or rotary mechanism. This pressure creates linear or rotary motion, which is transmitted to electrode holding components. The motion enables precise positioning and clamping force, ensuring electrodes are correctly aligned and securely held during manufacturing. The actuator's design allows for controlled movement, with pressure regulation providing variable force and speed. Closed-loop control can enhance positioning accuracy to ±0.05 mm. The mechanical output is directly proportional to the applied pressure, allowing for predictable and repeatable operation.
