Bolt va gayka Track Poyafzal segmenti Rolikli kesish uchun
Ekskavator murvatining va gaykaning standart o'lchamlari ekskavatorning markasi va modeliga qarab farq qilishi mumkin.Umumiy o'lchamlarga M12, M16, M20 va M24 kiradi.
1-qadam: Xom ashyoni tekshirish va saqlash
Bolt uchun xom ashyo dastur asosida dizayner tomonidan hal qilinadi.Tekshirish uchun ishlatiladigan material, keyin zang paydo bo'lishining oldini olish uchun to'g'ri saqlash joyini aniqlash va tegishli qoplamani ta'minlash kerak.
2-qadam: Tishlanmagan / Tugallanmagan murvat ishlab chiqarish
Bu bosqichda asosan quyma va zarbdan foydalaniladi. Boshqa usullardan ham foydalanish mumkin:
1. Sinterlash
2. Prototiplash (Tezkor)
3-qadam: CNC ishlov berish
Qism zarb / quyish yo'li orqali ishlab chiqarilgandan so'ng, u odatda CNC tomonidan kerakli o'lchamlarga ishlov beriladi.
Bu erda bajariladigan operatsiyalar: ishora qilish, qaratish, yiv ochish.
4-qadam: Issiqlik bilan ishlov berish
Mahkamlagichlarni kuchliroq qilish uchun ishlov berishdan keyin issiqlik bilan ishlov berish amalga oshiriladi.Qattiqlashtirish va chiniqtirish operatsiyalari bajariladi.
Birinchidan, murvat 850-900 ° S haroratgacha isitiladi va keyin sovutish muhitida so'ndirilishi uchun qattiqlashuv amalga oshiriladi.
Ikkinchidan, murvat kuchliroq bo'lib qolishi uchun haddan tashqari qotib qolgan murvatni yumshoqroq qaytarish uchun yana isitiladi.Qattiqlashuv paytida yuzaga kelgan murvatning mo'rtligini kamaytirish uchun qayta isitish amalga oshiriladi.
5-qadam: sirtni pardozlash
Keyingi - sirtni tugatish jarayoni.Odatda, silliqlash jarayoni sirtni tugatish spetsifikatsiyasiga muvofiq sirtni silliq qilish uchun amalga oshiriladi.
6-qadam: ipni siljitish
Jarayonni tugatgandan so'ng, iplarni o'rash ikkita matritsa bilan amalga oshiriladi.Ulardan biri statsionar, ikkinchisi esa murvatlarga bosim o'tkazib, iplarni hosil qiluvchi harakatlanuvchi matritsa.
7-qadam: qoplama
Iplarni aylantirgandan so'ng, zang va korroziyaning oldini olish uchun murvat va vintli mahkamlagichlar qoplanadi.Boltlarni qoplashning ajoyib namunasi - belgilangan soatlar soniga qarab SST (Tuz purkash testi) ga sinovdan o'tkaziladigan murvatlardagi geometrik qoplama.
FISCHERSCOPE deb nomlangan mashina qoplama qalinligini aniqlash uchun boshqa qalinlik o'lchash asboblari bilan bir qatorda qoplama qalinligi o'lchagichi kabi ishlatiladi.
8-qadam: Shakl, moslik va funktsiyani tekshirish:
Barcha jarayonlar amalga oshirilgandan so'ng, nihoyat qism tekshirishga o'tadi.U uchrashishi kerak
1.Moment sinovi, SST
2. Yong'oq bilan jihozlash
3. Ta'sir kuchi (Impact charpy testi)
4.Kuchlanish kuchi sinovi (murvatning % cho'zilishi)
5. Boltning asosiy qattiqligi
6.Qoplama qalinligi
O'lchovni tekshirish va boshqalar.
