I. Daily Maintenance: Basic Upkeep

Thorough Cleaning Post-ProductionUse a soft brush or compressed air (<=0.6MPa) to remove metal chips, dust, and residual oil from the die surface, cavity, and guide pillars. Avoid sharp tools; use specialized cleaner for stubborn residues and wipe dry immediately.

Apply high-temperature resistant lubricant (for >=150℃) to guide pillars, guide sleeves, ejector pins, and sliding surfaces. Use food-grade lubricants for medical/food packaging dies (compliant with FDA/CE).

Inspect protective covers, safety interlocks, and fasteners for looseness/damage. Ensure the ejection mechanism operates smoothly. Mark and repair abnormalities promptly.

II. Regular Maintenance: Scheduled Care

(1) Weekly Maintenance: Precision Calibration

Use a coordinate measuring machine or dial indicator to check key dimensions (cavity size, punch clearance) and parallelism. Adjust/grind parts if deviation exceeds ±0.01mm.

Replace turbid oil with metal particles. Clean the oil filter to prevent clogging.

(2) Monthly Maintenance: Deep Care

Disassemble punches, dies, and springs; clean with ultrasonic equipment. Replace severely worn parts (deformed springs, blunt punches) with genuine accessories.

Apply thick anti-rust oil, wrap in moisture-proof film, and store in a dry warehouse (15-25℃, humidity <=60%).

(3) Quarterly Maintenance: Comprehensive Evaluation

Conduct test stamping with standard workpieces. Evaluate accuracy, surface finish, and ejection stability; compare data with initial performance to address potential issues.

Check hardness of high-wear parts (e.g., H13 steel punches) with a portable tester. Reheat-treat (quenching + tempering) if hardness drops below HRC58-62.

III. Special Maintenance: Environment & Working Conditions

High-Temperature/High-Humidity EnvironmentsUse high-temperature resistant materials/lubricants in hot regions; increase maintenance frequency. Add desiccants and reapply anti-rust oil every 2 weeks in humid areas.

Clean dies with neutral detergent immediately after stamping stainless steel/aluminum alloy. Apply anti-corrosion lubricant to avoid chloride ion damage.

IV. Maintenance Taboos

Do not use low-quality lubricants or substitutes.

Avoid over-tightening fasteners during assembly.

Address minor abnormalities (noise, slight deviation) promptly to prevent major failures.
