Xususiyatlari va afzalliklari
Flanjli Bolt Din 6921 Cl 8.8 og'ir yuklarga mo'ljallangan ilovalarda keng qo'llaniladigan yuqori quvvatli mahkamlagichdir.Bu gardish murvatining bir turi bo'lib, u taglikdagi yuvish mashinasiga o'xshash gardish bilan ishlab chiqilgan bo'lib, u qo'shimcha yordam beradi va murvatni tebranish yoki moment tufayli bo'shashishiga yo'l qo'ymaydi.Bolt olti burchakli boshga ega, bu kalit yoki pense yordamida oson o'rnatish va olib tashlash imkonini beradi.
DIN 6921 standartiga muvofiq ishlab chiqarilgan bu gardishli murvat ipning o'lchami, uzunligi va qadami, shuningdek, material va mexanik xususiyatlar uchun maxsus talablarga javob beradi.U xrom, molibden va vanadiy kabi elementlar bilan qotishma qilingan o'rta karbonli po'latdan yasalgan bo'lib, uning mustahkamligi va chidamliligini oshiradi.Bolt shuningdek, korroziya va zang paydo bo'lishining oldini oladigan sink qoplamasi yoki galvanizatsiya kabi himoya qatlami bilan qoplangan.
Ushbu gardish murvatining 8,8 toifasi mavjud bo'lib, u kamida 800 N / mm2 valentlik kuchini va kamida 640 N / mm2 oquvchanligini ko'rsatadi.Bu uni yuqori siqish kuchi va charchoq, zarba va lateral kuchlarga qarshilik talab qiladigan ilovalarda foydalanish uchun mos qiladi.U odatda avtomobilsozlik, qurilish, mashinasozlik va sanoat uskunalarida qo'llaniladi.
Boltning uzunligi 10 mm dan 100 mm gacha yoki undan ko'p bo'lgan maxsus dastur talablariga qarab o'zgaradi.Ip o'lchami M6 dan M30 gacha yoki undan kattaroq, nozik, qo'pol va o'ta qo'pol kabi turli xil pitch turlari mavjud.Olti burchakli bosh flanesli yoki qirrali bo'lishi mumkin, shuningdek, ishlab chiqaruvchi yoki navni ko'rsatish uchun chuqurchaga yoki belgiga ega bo'lishi mumkin.
Umuman olganda, Flange Bolt Din 6921 Cl 8.8 mukammal mustahkamlik, barqarorlik va korroziyaga chidamlilikni ta'minlaydigan ishonchli va bardoshli mahkamlash yechimidir.Uning yuqori sifatli dizayni va aniq ishlab chiqarilishi turli og'ir yuklarga mo'ljallangan ilovalarda optimal ishlash va xavfsizlikni ta'minlaydi.
