Silindr piston rodini qayta ishlashning roli katta. Odatda mahsulot sifatini yaxshilash uchun o'raladi va u ham yuqori texnik talablarga ega bo'lgan harakatlanuvchi qismdir. Piston rodi pistonning ishini qo'llab-quvvatlaydigan uzluksiz qism bo'lib, asosan yog 'tsilindrining va silindrning harakatini bajarish qismlarining o'rtasida ishlatiladi. Boshqa harakatlanuvchi qismlarga nisbatan, piston rodi tez-tez harakatlanadigan va yuqori texnik talablarga ega bo'lgan harakatlanuvchi qismdir.
Silindr piston rodi silindrli barreldan, piston rodidan, silindrli novdadan, pistondan va so'nggi qopqoqdan iborat. Uning sirt pürüzlülüğü Ra0,4-0,8um ga yetishi uchun talab qilinadi va koaksiyallik va aşınma qarshilik talablari talab qilinadi. Ularning barchasi qattiqqo'l. Bundan tashqari, silindrli novdalar kabi nozik vallarni qayta ishlash har doim xodimlar uchun asosiy muammo bo'lib kelgan. Shuning uchun, ishlov berishda piston rodining texnik talablari uning juda muhim xususiyati hisoblanadi. Aytish mumkinki, ishlov berish texnologiyasining sifati mahsulot sifati va xizmat muddatiga shunchaki ta'sir qiladi.
The piston rod of the oil cylinder is an important part of the oil cylinder. It is usually made of 45 steel as a solid rod or an empty tube. The piston rod will be eroded by abrasive particles during use, which is very easy to wear. The current domestic ancient process is to hard chrome plating (coating thickness 0.030.05mm) and polishing, and its surface roughness Ra is 0.10.2μm. The plating solution is based on chromic acid and sulfuric acid as the catalyst. The advantages of the process are: the plating solution is stable, easy to operate, the quality of the surface chrome coating is relatively high, and the oil pole is bright, high hardness, and excellent wear resistance.
Piston rodining ishlov berish sifati mahsulot sifatiga ta'sir qilishi mumkin, shuning uchun tanlashda e'tibor bering, piston rodini qayta ishlash sirt eroziyaga chidamliligini yaxshilashi mumkin va piston rodi charchoq yoriqlarining paydo bo'lishini yoki kengayishini kechiktirishi mumkin, shu bilan yaxshilanadi. silindr tayog'ining charchoq kuchi. .
Rulonni shakllantirish orqali haddelenmiş yuzada sovuq ishlov berilgan qattiq qatlam hosil bo'ladi, bu silliqlash juftligining aloqa yuzasining elastik va plastik deformatsiyasini kamaytiradi, shu bilan silindr tayog'i yuzasining aşınma qarshiligini yaxshilaydi va silliqlash natijasida kelib chiqqan kuyishdan qochish. Prokatdan so'ng, sirt pürüzlülüğü qiymatini kamaytirish mos keladigan xususiyatlarni yaxshilashi mumkin. Shuni bilish kerakki, piston rodi piston rodining ichki qismida qisqa yoki uzun bo'lishi mumkin va uning ishonchliligi kompressorning ishlashiga bevosita bog'liq. Shuning uchun, piston rodining yaroqsizligi masalasi ham haqiqatdir. Xromlangan novda ishlab chiqaruvchining piston rodining yaroqsizligining sabablari ko'p, masalan, noto'g'ri ishlov berish, qoniqarsiz issiqlik bilan ishlov berish va boshqalar.
