راه حل

در زیر خلاصه ای از راه حل های مشکلات رایج ماشین های برش لیزری ، همراه با تعدادی از اسناد فنی و تجربه عملی صنعت ، شامل جنبه های مکانیکی ، نوری ، الکتریکی و بهره برداری و نگهداری و سایر جنبه ها آمده است:

1. مشکلات کیفیت برش

1. برش مداوم یا برش خشن

بررسی کنید که آیا تنظیم توان لیزر خیلی کم است و پارامترهای توان پتانسیومتر یا نرم افزار را تنظیم کنید.

لنزهای فوکوس آلوده / فرسوده و لنزهای بازتابنده را تمیز یا جایگزین کنید تا مطمئن شوید که مسیر نور عاری از انحراف است.

فاصله کانونی را در موقعیت بهینه تنظیم کنید و از ابزار تست موقعیت فوکوس برای کالیبره کردن استفاده کنید.

خلوص گاز کمکی (مانند نیتروژن یا اکسیژن) را بررسی کنید و فشار را به مقدار توصیه شده تنظیم کنید.

2. انحراف اندازه برش یا تغییر شکل الگو

معادل پالس سیستم کنترل عددی را کالیبره کنید و پارامترهای مرحله را در نرم افزار تنظیم کنید.

بررسی کنید که آیا پیچ چرخ همگام سازی شل است ، آیا کشش تسمه مناسب است یا خیر ، و قطعات مکانیکی را سفت کنید.

اگر افت پله در حین برش دینامیکی رخ دهد ، لازم است سرعت پردازش کاهش یابد یا پایداری درایور موتور بررسی شود.

3. سوراخ یا جرقه غیر طبیعی

نازل های فرسوده را تعویض کنید و فشار گاز را بهینه کنید (به عنوان مثال ، برای برش فولاد ضد زنگ به نیتروژن تغییر دهید).

افست موقعیت فوکوس لیزر را بررسی کنید و مسیر نوری را دوباره کالیبره کنید.

برای مواد بسیار بازتابنده (مانند آلومینیوم ، مس) ، از فناوری سوراخ کردن پالس استفاده کنید یا پوشش های ضد انعکاس اضافه کنید.

خطاهای مکانیکی و الکتریکی

1. حرکت غیر طبیعی ماشین (راه رفتن تصادفی ، گیر کرده)

اتصال زمین را برای از بین بردن تداخل استاتیک بررسی کنید.

تست کنید که آیا شفت موتور شکسته است ، آیا یاتاقان چرخ سنکرون آسیب دیده است یا خیر ، و قطعات آسیب دیده را به موقع تعویض کنید.

ولتاژ منبع تغذیه درایور (معمولاً 24-60 ولت DC) را بررسی کنید و از یک مولتی متر برای بررسی پایداری منبع تغذیه سوئیچینگ استفاده کنید.

2. خرابی لیزر یا کاهش توان

بررسی کنید که آیا سیستم گردش آب نرمال است یا خیر و اگر دمای آب از 40 درجه سانتیگراد بیشتر شد ، آب خنک کننده را تعویض کنید.

تست سیگنال AIN و + 5 ولت منبع تغذیه لیزر را اتصال کوتاه کنید ، اگر نور خارج شود ، خرابی پتانسیومتر است.

لوله لیزر قدیمی (اگر تضعیف نور بیش از 20 ٪ باشد) یا قسمت احتراق خط فشار قوی را تعویض کنید. اکثر خطاها را می توان با عیب یابی اولیه (مانند تمیز کردن لنز ، بررسی منبع تغذیه) حل کرد. مشکلات پیچیده باید با کتابچه راهنمای تجهیزات و پشتیبانی حرفه ای ترکیب شوند. تعمیر و نگهداری منظم می تواند خرابی های ناگهانی را تا 80 ٪ کاهش دهد. برای کاربران در سطح سازمانی ، توصیه می شود به روند ارتقاء تجهیزات هوشمند برای افزایش رقابت طولانی مدت توجه کنند. برای موارد دقیق تر ، لطفاً به کتابخانه خطای شبکه بین المللی پردازش فلز مراجعه کنید.
