PARMALASH OPERATSIYALARIDA MEXANIK ISHLOV BERISH MAROMLARI VA ISHCHI YUZALAR VAQTINI DETAL TAYYORLASH
Parmalash dastgoxlari detallarda teshib ochib ishlov berishda keng qo'lanadigan dastgohlardandir. Parmalash dastgohlarnii har xil (Gorizantal, Vertikal, Radial) modellari mavjud bo'lib vertikal bir shpindelli parmalash dastgohlari, shuningdek, maxsus ko 'p shpindelli parmalash va teshik kengaytiruvchi dastgohlar shular qatoriga kiradi.
Kalit so'zlar: RDB dastgohlar, radial parmalash, Bir shpindelli vertikal parmalash dastgohi.
Drilling machines are one of the most widely used tools for drilling in details. There are different models of drilling machines (Horizontal, Vertical, Radial), including vertical single-spindle drilling machines, as well as special multi-spindle drilling and hole-expanding machines.
Keywords: RDB lathes, radial drilling, Single-spindle vertical drilling machine.
Сверлильные станки являются одним из наиболее широко используемых инструментов для сверления деталей. Существуют различные модели сверлильных станков (горизонтальные, вертикальные, радиально-сверлильные), в том числе вертикально-сверлильные станки одношпиндельные, а также специальные многошпиндельные сверлильные и сверлильные станки.
Ключевые слова: токарные станки РДБ, радиально-сверлильный станок, одношпиндельный вертикально-сверлильный станок.
Dastlabki ishlab chiqarilgan universal teshib kengaytiruvchi dastgoxlarni bazalarida yangi yangi RDB dastgoxlarni ishlab chiqarish yo'lga qo'yilgan. Mashinasozlik ishlab chiqarish korxonalarida ko'p qo'laniladigan dastgox radial parmalash dastgoxlari bo'lib 25 mm - 100 mm bo'lgan teshiklarga ishlov berish uchun mo'ljallangan.

1-rasm. Vertikal radial parmalash dastgohidagi qismlar.
Shuningdek Universal teshik kengaytiruvchi gorizontal teshish dastgoxlari bo'lib 80-320 mm teshiklarini kengaytirishda qo'llaniladi. Aniq yuzalarga ishlov berish uchun esa kordinatali yo'nib kengaytiruvchi dastgoxlari shuningdek, RDB boshqariluvchi dastgoxlar (avtomatik ravishda16 keskichlarni almashtiruvchi) dastgoxlar ishlab chiqishda o'z samarasini bermoqda.Teshish jarayoni tahlil qilib 3 xil dastgohni qabul qilib olamiz va ularni ishlab chiqarishdagi ish unumini tahlil qilib chiqamiz. Demak birinchi taxlil qiladigan dastgoximiz 2N135 Vertikal parmalash dastgohi bo'lib bu dastgohlar mashinasozlikning ko'p sohalarida ishlatiladi ayniqsa sozlash ustaxonalarida, katta va kichik mexanik ishlov berish sexlarida ko'p qo'llaniladi, bu dastgohlar donalab ishlab chiqarish sharoitiga moslashtirilgan.
Tadqiqotlar shuni ko'rsatadiki RDB dastgohlarini iqtisodiy samaradorligi ishlab chiqarish unumdorligini oshishi, o'z yordamchi vaqt sarflanishi bilan universal dastgohlardan farq qiladi. Ammo RDB dastgohlarning tannarxini bir necha barobar universal dastgohlardan qimmatligi har xil ishlab chiqarishi sharoitlarida o'zini oqlamasligi mumkin.

Bir shpindelli vertikal parmalash dastgohi boshqarilishi qo'lda bajariladi ya'ni (rejimlami tanlanishi, teshiladigan zagatovkalarni shpindelni o'qi bo'yicha moslash, ishchi qo'lda to'g'rilab teshashi)bu albatta yordamchi vaqtni oshirishga olibkeladi,shuningdek dastgoh stoli ham harakatlanmaydi. Ammo foydali tomoni chuqur va oddiy teshiklarni tashishda parmani detalga olib borishga va chiqarishga asosiy vaqt oz sarflanadi, ammo yordamchi va asosiy vaqt yig'indisi vaqtini ko'pligi bilan boshqa ishlab chiqarish (kichik seriyalab va ko'plab ) turlarida o'zini oqlamaydi. Keyinchalik vertikal parmalash dastgoxlari bazasida, dastgoxni ish unumini oshirish maqsadida xarakatlanuvchi pozitsiyali stol qo'lanilgan . Keyingi ko'rib chiqadigan dastgoximiz 2M55 Radial - Pramalash dastgohlari bu dastgohlarda ham vertikal parmalash dastgohlaridagi kabi texnologik operatsiyalar bajariladi. Bular teshish, teshib kengaytirish, tores yuzalarini,17 ayrim hollarda yo'nib kengaytirish, konovkalarni yo'nishi, disksimon detallarni listlardan qirqib oladi va bir qator imkoniyatlar mavjud.
Vertikal parmalash dastgohdan asosiy farqi shundaki ishlash jarayonida tashiladigan detal harakatlanmaydi, faqat teshadigan keskich golovkasi yengil harakatlanib ishlov beradi: bu katta detallarga ishlov berishda samara beradi shuningdek Radial parmalash dastgohlarini shpindelini aylana bo'yicha va radius bo'yicha harakatlantirish mumkin. Shuning uchun bu dastgoh donalab, mayda seriyalab va o'rta seriyalab ishalb chiqarish sharoitida ishlatiladi.
Kamchiligi - zagatovka ishlov berishga uchun ketadigan yordamchi vaqtni kattaligi bo'lib uni qisqartirish maqsadida rodial parmalash dastgohini mexanizmlari va yordamchi qurilmalari godravlik tarzda boshqariladi. Dastgoxni yaxshi tomonlari katta detallarga koordinata bo'yicha harakatlanib ishlov berishi va katta diametrlarni teshishda pozitsiyalashga ketadigan vaqtni ozligida (ko'p teshiklarni teshishda bir teshikdan ikkinchi teshikni teshish uchun shindelni xarakatlaninishi) va tezlik qutisini imkoniyati kattaligidadir.
Yuqorida ko'rib chiqgan universal parmalash dastgohlarini ishlatish uchun asosan yuqori malakali ishchilar talab etiladi, shuningdek teshish jarayonini malakadi ishchisiz amalga oshirib bo'lmaydi, chunki zagotovka o'rnatib, teshish operatsiyasini nazorat qilish va zagotovka almashtirish ishchiga bog'liq shu muammolarni hal etish maqsadida RDB Parmalash dastgohlarini ishlab chiqarish yo'lga qo'yildi.

Hozirgi kunga kelib avtomatlashtirilgan ishlab chiqarish korxonalarida keng qo'llanib kelinayotgan RDB dastgohlari o'zini qulayligi ishni sifatli, tez va ishchi kuchi sarflanmagan holda ishlov berishligi bilan ajralib turadi.
