The choice of tools for daily maintenance of stamping dies directly affects maintenance efficiency and die life. A proper tool configuration can improve maintenance accuracy and reduce human-caused damage. The following are recommendations for practical and easy-to-use maintenance tools for industrial scenarios:
Basic Cleaning and Protection Tools
Keeping the die clean is the first step in maintenance, especially after shutdown, removing metal filings and oil stains is crucial:
High-Pressure Air Gun: Used to blow away fine metal filings and dust from hard-to-reach areas such as cavities and guide pillars, preventing scratches from hard objects.
Lime-Free Cloth/Cotton Cloth: Used with alcohol or detergent to wipe the die surface, ensuring no fiber residue remains.
Toothbrush (Soft Bristle): Used to clean small grooves, vent holes, and threaded holes, especially suitable for the cutting edge area of trimming dies.
Work Gloves and Sleeves: Prevent hand sweat from corroding the die surface and protect operator safety.
Lubrication and Rust Prevention Materials
Insufficient lubrication is a major cause of guide post jamming and accelerated wear. Specialized lubrication products are required:
Specialized Lubricating Oil: Used for sliding parts such as guide posts, guide sleeves, and return pins. It is recommended to use a synthetic oil with high temperature resistance and strong oxidation resistance.
Rust Inhibitor/Rust Agent: Apply a thin protective coating to the cavity and mold surface after production to form a 5-10μm protective film, providing effective rust prevention for up to 72 hours.
Molybdenum Disulfide Containing Gear Oil: Suitable for worm gear transmission mechanisms, reducing gear meshing wear by more than 40%.
Note: Do not apply oil to the parting surface, ejector pin heads, or other molding areas to avoid affecting the surface quality of the parts.
Inspection and Adjustment Tools
To ensure stable mold accuracy, regular dimensional and condition checks are necessary:
Micrometer/Vernier Caliper: Used to measure the clearance between the punch and die and the wear of the cutting edges. Zeroing is required before use.
Torque Wrench: Used to check the tightness of bolts to prevent misalignment or safety accidents caused by loosening. Ultrasonic Cleaner: Suitable for deep cleaning of high-precision molds, removing stubborn oil stains without damaging the surface.
Triaxial Accelerometer (Optional): Used for abnormal vibration identification, combined with FFT spectrum analysis to determine guide sleeve wear or loose bolts.
