The maintenance and care of stamping dies mainly includes the following aspects:
Regular Cleaning: After each use, oil, metal shavings, and dust must be removed from the die surface. Special cleaning agents or compressed air can be used for cleaning; avoid using highly corrosive chemicals. After cleaning, apply rust-preventive oil to prevent rusting.
Lubrication Maintenance: Sliding parts of the die (such as guide pillars and guide sleeves) need to be lubricated regularly. High-temperature grease is recommended, with a frequency of every 5000 stamping cycles or once a week. Insufficient lubrication will lead to accelerated wear and affect the die's lifespan.
Wear Inspection: Regularly inspect the wear of critical parts of the die, such as the cutting edges, punches, and dies. If dulling or cracks are found on the cutting edges, they should be sharpened or replaced promptly. A comprehensive inspection is recommended after every 10,000 stamping cycles.
Storage Environment: Dies should be stored in a dry, ventilated environment, avoiding moisture and high temperatures. Dies not used for extended periods should be coated with rust-preventive oil and covered with a dust cover.
Avoid overloading: Strictly adhere to the mold's design load during operation to prevent overloading, which can easily lead to mold deformation or cracking.
Regular calibration: Mold components such as locating pins and guide pillars require regular calibration to ensure accuracy. Professional calibration is recommended every 3 months.
Maintenance log: Record the date, content, and any issues discovered after each maintenance session to facilitate tracking of mold status and predicting its lifespan.
