Hydraulic Hose Crimping Machine Operating Guide

I. Pre-Operation Preparation

1. Equipment Inspection

- Hydraulic System: Check the hydraulic oil level (should be above the centerline of the oil window) and ensure the oil is clean and free of impurities.

- Power/Air Source: Ensure the power supply voltage is stable (e.g., 380V/220V). For pneumatic equipment, check that the air pressure meets the standard (usually 0.6-0.8MPa).

- Die Inspection: Select a die that matches the hose and fitting. Check that the die is free of wear and cracks and securely installed.

2. Hose and Fitting Compatibility

- Specification Verification: Confirm the hose model (e.g., 2SN, 4SP), fitting type (e.g., 24° cone, flat seal), and crimping dimensions (refer to the machine's crimping parameter table).

- Cleaning: The hose cut should be smooth and free of burrs, and the connector and hose inner wall should be free of oil, dirt, and impurities.

3. Safety Precautions

- Operators should wear protective gloves and goggles to avoid injury from high-pressure oil splashes or metal debris.

- Ensure the work surface is clean and free of clutter.

II. Operation Procedure

1. Clamping the Hose and Connector

- Insert the hose into the connector, ensuring the insertion depth meets the standard (the connector usually has a positioning step or marking).

- Place the assembled hose connector into the center of the crimping machine die, ensuring alignment without deviation.

2. Setting the Crimping Parameters

- Adjusting the die stroke: Set the crimping distance according to the hose specifications (e.g., a Φ10mm hose has a crimped diameter of approximately 9.2mm).

- Setting the pressure: Refer to the equipment manual or crimping parameter table (e.g., approximately 50-100 MPa for low-pressure hoses and 100-200 MPa for high-pressure hoses).

3. Start the crimping process

- Press the start button (or foot switch) with both hands and observe the crimping process:

- The pressure gauge should rise steadily without drastic fluctuations.

- After crimping is complete, the mold will automatically return to its original position.

4. Check the crimping quality

- Visual inspection: The crimped joint should be even and free of cracks, and the connector and hose should not be loose.

- Dissection (random inspection): Open a sample to check whether the core tube is deformed evenly and the wire layer is compacted.

- Pressure test: If necessary, perform a pressure test at 1.5 times the working pressure to confirm there are no leaks.

III. Operating Precautions

1. Do not over-pressurize: Excessive crimping pressure can damage the hose, while insufficient pressure can cause leakage.

2. Do not use air compressors: Do not crimp without a hose in the mold to avoid damage.

3. Troubleshooting:

- If the equipment makes unusual noises or the oil temperature is too high, stop the machine immediately for inspection.

- If the hose is loose or leaking after crimping, adjust the mold or replace the connector.

4. Collaboration: Dedicated personnel are required to operate the machine to avoid accidental activation of switches.

IV. Equipment Maintenance and Care

1. Daily Maintenance

- Clean mold debris and wipe off oil stains daily.

- Check the hydraulic oil level and replace it regularly (recommended every 6 months or 2000 hours).

2. Long-Term Out of Service

- Release the hydraulic system pressure and apply anti-rust oil to the mold.

3. Regular Inspection

- Check the oil pipes and seals for aging and the electrical wiring for integrity.

Summary

- Strictly follow the specifications for tightening and pressing, and avoid operating based on experience.

- Perform regular maintenance to ensure long-term stable operation.

- Operators must be trained and familiar with emergency response procedures.
