High-speed stamping die cleaning process, die oil cleaning
I. Common Types of Dirt on Stamping Dies
1. Oil stains and lubricating residue: Residues of lubricating oil, release agents, etc., used during stamping.
2. Metal debris: Small particles such as aluminum chips and iron chips generated during stamping.
3. Oxide layer and corrosion: Oxide layer formed on the surface of the die after long-term storage or use.
4. Adhesive residue: Residues of sealants or adhesives used in some processes.
II. Cleaning Process Flow (Detailed Step-by-Step Explanation)
1. Pre-treatment stage: Initial manual cleaning: Use soft brushes, air guns, or vacuum equipment to remove large debris and loose dirt from the surface of the die.
Degreasing treatment: Spray environmentally friendly degreasing agents on areas with serious oil stains to soften stubborn oil stains.
2. Main cleaning stage
High-pressure water cleaning
Equipment: Industrial-grade high-pressure cleaning machine (pressure range 50-150 MPa, adjustable temperature).
Process: Use a fan-shaped nozzle to rinse the die grooves, holes, and other complex structures with 60°-80℃ hot water and neutral cleaning agent.
Advantages: Efficiently removes oil stains and debris, avoiding damage to the die surface.
Ultrasonic cleaning (optional)
Applicable scenarios: Precision dies or deep hole/blind hole structures.
Process: Immerse the die in an ultrasonic tank to peel off micron-level residues through high-frequency vibration, and use special cleaning agents to improve the effect.
3. Post-treatment stage
Rinsing and drying
- Rinse the surface of the die with deionized water or pure water to avoid scale residue.
- Dry with compressed air or low-temperature drying oven (temperature ≤ 80℃) to ensure the die is completely dry.
Rust prevention treatment
- Spray water-based rust inhibitors or perform short-term oil sealing to prevent oxidation during storage.
III. Cleaning Quality Inspection Standards
1. Visual inspection: No visible oil stains, debris, or water stains on the surface of the die.
2. White glove test: Wipe the surface of the die with a clean white cloth, no black stains.
3. Functionality verification: After cleaning, assemble the die for test stamping to ensure that the stamped parts have no scratches, indentations, or other defects.
IV. Safety and Environmental Protection Requirements
1. Operational safety
- Wear protective equipment (goggles, gloves) for high-pressure equipment.
- Set warning signs during high-temperature cleaning to avoid burns.
2. Environmental protection measures
- Cleaning wastewater needs professional treatment to meet discharge standards.
- Prioritize biodegradable cleaning agents to reduce environmental pollution.
V. Equipment Recommendations and Process Optimization Suggestions
1. Adaptable equipment
- High-pressure cleaning machine (recommended pressure 100 MPa or higher, with heating function).
- Multi-tank ultrasonic cleaning line (for small and precise dies).
2. Process optimization
- Adjust the pH value of the cleaning agent according to the die material (such as steel, aluminum) to avoid corrosion.
- Regularly maintain cleaning equipment to ensure pressure and temperature stability.
