Mounting & Dimensional Specifications

Mounting Interface

Flange Diameter: 20.36 inches - defines the overall width of the sealing and contact surface.
Bolt Pattern (Bolt Circle Diameter): 19.00 inches - specifies the circular arrangement of the mounting bolts for alignment.
Bolting Configuration: 24 units of 3/8-24 UNF threaded fasteners - indicates the quantity and standard thread type for secure attachment.

Envelope & Operational Range

Maximum Housing Diameter: 22.7 inches - the greatest outer width, important for spatial clearance during installation.
Nominal Installed Height: 9.5 inches - the reference height under standard assembly conditions.
Usable Stroke Range: 3.3 to 13.0 inches - the approved vertical displacement between fully compressed and fully extended positions.

Installation Procedure

Step	Key Operation	Technical Points & Illustration Notes
1. Positioning	Place the air spring between the upper die holder and the press frame top plate at the designated mounting location.	Alignment Requirement: The central axis of the spring must align with the press ram centerline, with a permissible deviation ≤ 0.2°. Diagram should indicate measurement points.
2. Bolt Pre-tightening	Insert bolts (e.g., 24 pieces of Grade 8.8 or higher) through the spring flange holes (e.g., 24×φ9.5mm) and into the frame's threaded holes. Tighten in stages.	Tightening Sequence: Follow a cross-diagonal pattern in two stages (first 50% torque, then 100% final torque). Torque value must comply with bolt specification (e.g., for 3/8-24 UNF, suggested torque is 28-32 N*m).
3. Pneumatic Connection	Connect the factory air supply line to the spring's inlet port via a filter regulator. Recommend using PT thread sealing.	Pressure Setting: Initial pressure should be set at 50% of the nominal working pressure (e.g., if working pressure is 8 bar, start at 4 bar), then fine-tune according to load.
4. Stroke Calibration	Jog the press manually and measure the actual extension/compression range of the spring.	Stroke Protection: Ensure the spring's stroke always remains within the specified range (e.g., 3.3-13 inches). This can be achieved by adjusting the frame's limit bolts.
5. Seal Verification	Pressurize the spring to 1.2 times the working pressure and hold for 15 minutes.	Leak Test Method: Apply soap solution to the flange mating surface. Check for continuous bubble formation. Allowable pressure drop ≤ 0.1 bar/minute.
6. Load Testing	Perform continuous stamping using standard test plates and monitor the spring's dynamic response.	Performance Criterion: The spring should maintain linear compression during operation without abnormal vibration or deviation. A laser displacement sensor can be used for monitoring.
