Решение

Ниже приводится краткое изложение решений общих проблем лазерной резки, организованное в сочетании с несколькими техническими документами и отраслевым практическим опытом, охватывающим механические, оптические, электрические и эксплуатационно-техническое обслуживание и другие аспекты:

1. Проблемы качества резки

1. Непрерывная резка или грубый разрез

Проверьте, не является ли настройка мощности лазера слишком низкой, отрегулируйте потенциометр или параметры мощности программного обеспечения.

Очистите или замените загрязненные / изношенные фокусирующие линзы и светоотражающие линзы, чтобы гарантировать, что путь света не смещается.

Настройте фокусное расстояние в наилучшее положение и используйте инструмент для проверки положения фокуса для калибровки.

Проверьте чистоту вспомогательного газа (например, азота или кислорода). Если давление недостаточно, его необходимо отрегулировать до рекомендуемого значения.

2. Отклонение размера выреза или графическая деформация

Калибруйте импульсный эквивалент системы числового управления и отрегулируйте пошаговые параметры программного обеспечения.

Проверьте, не ослаблен ли винт синхронного колеса, подходит ли натяжение ремня, и затяните механические части.

Если происходит потеря шага при динамической резке, необходимо снизить скорость обработки или проверить устойчивость двигателя водителя.

3. Бурр или ненормальная искра

Замените потерянное сопло и оптимизируйте давление газа (например, резка нержавеющей стали для использования азота).

Проверьте смещение положения фокуса лазера и откалибруйте оптический путь.

Для материалов с высокой отражающей способностью (таких как алюминий и медь) используйте технологию импульсной перфорации или добавьте антибликовое покрытие.

Во-вторых, механический и электрический отказ

1. Аномальное движение машины (случайное блуждание, карта)

Проверьте заземление соединения для устранения статических помех.

Проверьте, не поврежден ли вал двигателя, не поврежден ли подшипник синхронного колеса, и своевременно замените поврежденные детали.

Проверьте напряжение источника питания водителя (обычно 24-60 В постоянного тока) и используйте мультиметр для проверки стабильности импульсного источника питания.

2. Лазер не производит свет или ослабление мощности

Проверьте, является ли система циркуляции воды нормальной. Если температура воды превышает 40 ° C, охлаждающую воду необходимо заменить.

Проверка сигнала AIN и + 5V короткого подключения лазерного источника питания. Если свет выходит, это отказ потенциометра.

Замените стареющую лазерную трубку (если затухание света превышает 20%) или зажигательную часть высоковольтной линии. Большинство неисправностей можно устранить путем простого устранения неполадок (например, очистки объектива, проверки источника питания). Сложные проблемы необходимо сочетать с руководствами по оборудованию и профессиональной поддержкой. Регулярное техническое обслуживание может уменьшить внезапные сбои на 80%. Пользователям корпоративного уровня рекомендуется обратить внимание на тенденцию интеллектуального обновления оборудования для повышения долгосрочной конкурентоспособности.
