Nayva va quvur qilish

Sep 17, 2026

Trubalar va quvurlar qismi nominal ichki diametr boʻyicha emas, balki tashqi diametr va devor qalinligi boʻyicha belgilanadi; shuningdek, egilish usuli qismning chizma asosida ishlab chiqarilishi mumkin yoki mumkin emasligini aniqlaydi. Bu sahifa trubani chizmada qanday belgilash kerakligini tushuntiradi va uning toʻgʻri belgilanganidan soʻng kesish, egish va payvandlash qanday nazorat qilinishini koʻrsatadi.

Chizmada trubani qanday belgilash kerak

Truba chizmasida nima koʻrsatilishi kerak — va bu nima uchun muhim
Parametr Koʻrsatiladigan narsalar U nima maqbul
Material va darajasi masalan: 304 martta, uglerodli poʻlat, 6061 aluminий Egilish rejalashtirilishidan oldin shakllanish qobiliyati, payvandlanish qobiliyati va korroziyaga chidamlilikni belgilaydi
Tashqi diametr Aniq tashqi diametr millimetrlarda Truba tashqi diametri boʻyicha sotiladi va egiladi; nominal ichki diametr trubani aniqlamaydi
Devor qalinligi Millimetrlarda nominal devor yoki uning standarti bilan birga o'lchov qilish Quvurning burilishda burilish radiusi minimal qiymatini, og'irligini va mustahkamligini belgilaydi
O‘rganish radiusi Markaz chizig'i radiusi yoki tashqi diametr nisbati radiusi Qattiqroq radiuslar uchun kalipda qo'shimcha qo'llab-quvvatlash talab qilinadi va ular uskunalar ishlab chiqarishdan oldin DFM tekshiruvida tasdiqlanadi
Burilish burchagi va pozitsiyalari Burchak hamda burilishning urinish nuqtalari orasidagi masofa Quvur burilishi quvurning uchlari emas, balki urinish nuqtalari orasida boshqariladi
Тохироқ усуллари Kesilgan, burilgan, kesilgan, tekislangan, delangan, teshilgan yoki rezba o'ralgan Keyingi operatsiyalarni va detalinga kerak bo'ladigan gigiyani aniqlaydi
Miqdor va bosqich Namuna, sinov ishlab chiqarish yoki seriyali ishlab chiqarish hajmi Egri chizish CNC egri chizg’ichda yoki maxsus kalipda amalga oshiriladimi yoki yo’qmi qaror qiladi

Kesish, egri chizish va payvandlash

  • Naychalar va plitali detallarning lazer bilan kesilishi; kesilgan va shakllantirilgan varaq metall ishlashda 0,1 mm atrofida aniqlik saqlanadi
  • Dastur bilan boshqariladigan egri chizish pozitsiyalari bilan CNC naycha egri chizish; shu tufayli birinchi detaldan boshlab takrorlanuvchi detallar mos keladi
  • Takrorlanuvchi geometriyani ta’minlash uchun jig’lar va fixturalarda naycha montajlarini MIG, TIG va nuqtaviy payvandlash
  • Mos kelish talab qilganda 0,01 mm atrofida aniqlikda kiritmalar, do’ppilar va oxirgi qismlarni CNC usulida ishlash
  • Qo’shimcha yakuniy ishlov berish sifatida sink bilan qoplatish, changli puxta qoplatish, passivatsiya qilish va g’ildirak bilan ishlash

20 000 dona dasturda sinab ko’rilgan

Motor tsiklida yon tomon qo’llab-quvvatlovchi qisqich loyihasida biz CNC naycha egri chizishni DFM asosida montajni qayta ishlash bilan birlashtirib 20 000 dona detallar ishlab chiqardik. Bu naycha ishlashning namunaviy sxemasi: avvalo texnik talablarni va egri chizish parametrlarini aniq belgilang, keyin hajm asosan kalip va fixtura loyihalashga bog’liq bo’ladi, qayta ishlashga emas.

Qo'rqituvchi, naycha yoki shakllantirilgan varaq — qaysi birini tanlash kerak

  • Qo'rqituvchi — ramkalar, reyka, tutqichlar va konstruktiv guruhlar uchun qattiqlik va og'irlik jihatidan samarali tanlovdir
  • Shakllantirilgan varaq — bo'sh kesim kerak bo'lmagan qopqoqlar, himoya qilgichlar, qopqoqlar va guruhlar uchun mos keladi
  • Naycha odatda suyuqlik o'tkaziladigan joylarda ishlatiladi, shu sababli ichki diametr (bore) va bosim konstruktiv qattiqlikdan ahamiyatliroqdir
  • Detalda ikkala xususiyat ham talab qilinsa, qo'rqituvchi va varaq bitta montajga payvandlanadi, ularni bitta jarayonga majbur qilish o'rniga

Tez-tez beriladigan savollar

Qo'rqituvchi ichki diametri yoki tashqi diametri bo'yicha belgilanadimi?

Konstruktiv qo'rqituvchi tashqi diametri va devor qalinligi bo'yicha belgilanadi. Nominal ichki diametr (bore) faqat naychaning taxminiy oqim hajmini ko'rsatadi va siz oladigan tashqi diametrni aniqlamaydi, shuning uchun chizmada OD (tashqi diametr) va devor qalinligini ko'rsating.

Qo'rqituvchining minimal egilish radiusi qancha?

Bu materialga, devor qalinligiga va radiusning tashqi diametrga nisbatiga bog'liq bo'ladi va uni DFM tekshiruvida taxmin qilinmaydi, balki tasdiqlanadi. Agar chizmada juda kichik radius talab qilinsa, bizga devor qalinligi va darajani dastlab aytib bering, shunda biz sizga matritsa va mandrel kerakligi haqida maslahat berishimiz mumkin.

Siz kvadrat va to'rtburchak trubalarni egasizmi?

Ha. Kvadrat va to'rtburchak kesimlar mos kesim uchun mo'ljallangan asbob-uskunalar yordamida egiladi va bir xil o'lchamdagi aylana trubaga nisbatan erishiladigan radius farq qiladi, shuning uchun kesim va radius birgalikda ko'rsatilishi kerak.

Siz faqat egilgan trubalarni emas, balki payvandlangan truba montajlarini ham yetkazib bera olasizmi?

Ha. Trubalar kesilishi, egilishi, kesilishi va qo'shimcha qismlar — qo'llab-quvvatlovchi plastinkalar, plitalar va ishlangan detallar bilan payvandlanishi mumkin, natijada yakuniy montaj tayyorlanadi va o'rnatishga tayyor holda yetkazib beriladi — bu alohida etkazib beruvchilar tomonidan ishlab chiqilgan qismlar orasidagi aniqlik muammolarini oldini oladi.

Qanday materiallar bilan ishlashingiz mumkin?

Stalga qarshilik ko'rsatuvchi po'lat, uglerodli po'lat, alyuminiy, mis va latun. Material darajasi, devor qalinligi va yuzaki qoplamasi detalinga qo'yiladigan yuk va uning ishlaydigan muhitiga mos ravishda DFM tekshiruvi davomida tasdiqlanadi.
