Tez-tez ishlatiladigan bosimli tekislash mashinalari, issiq yoki sovuq bo'lishidan qat'i nazar, inson ta'siri tufayli tekislash aniqligi 2 mm ga yetishi mumkin. Odatda, piston rodini nitridlash bilan ishlov berishdan so'ng, ba'zi mahsulotlar 0.1-0.3 mm egilish deformatsiyasiga ega, bunday kichik deformatsiyani bosimli tekislash mashinasi bilan tekislash talablarga javob bera olmaydi. Jasoratli urinishlar va amaliy tekshirish orqali biz tekislash uchun tebranishlarni egish va taqillatish usulidan foydalanamiz. Zanglamaydigan po'latdan yasalgan piston rodining ikki uchini qo'llab-quvvatlash uchun ikkita V shaklidagi dazmoldan foydalaning, o'rtasiga terish ko'rsatkichini o'rnating, piston tayog'ini qo'l bilan aylantiring, piston rodining yuqoriga va pastga sakrash qiymatini yozing va yuqori va yuqori nuqtalarni belgilang. novdadagi past nuqtalar. Bosim plastinkasi murvatini 5-10 mm pastga bosing, uni harakatsiz ushlab turing, egilish kuchlanishini barqarorlashtirish uchun milga mis novda bilan bir necha marta teging. Mis sterjenning qattiqligi 130-160HB, porshen rodning qattiqligi esa 280-300HB. Mis novda porshen rodiga qaraganda yumshoqroq bo'lgani uchun u urilayotganda uning yuzasi deformatsiyalanmaydi.
Remove the pressure plate and recheck the runout of the stainless steel piston rod. If the jump exceeds the standard, it can be straightened again until it is qualified. Good patience and experience are required during this period. A batch of piston rods were straightened by this method, and after being placed for 5>kunlarda yugurish qiymati yana tekshirildi va hech qanday rebound hodisasi topilmadi, bu esa bu tekislash usulini amalga oshirish mumkinligini ko'rsatadi.
