Ukucaciswa okuningana kwe-ASTM kudinga ikhanda le-hex elikhulu kunekhanda elijwayelekile (eliqediwe) le-hex.Le mininingwane ifaka phakathi: A193, A320 kanye ne-A307B.Nakuba amabhawodi e-A325 kanye ne-A490 nawo edinga ikhanda le-hex elisindayo, sicela ubhekisele ku-Structural Bolts ukuze uthole ukucaciswa kobukhulu, njengoba lawa mabhawodi anobude obufushane bentambo kunamabhawodi esindayo ajwayelekile we-hex.
Isicelo seHeavy Bolts
Amabhawodi asindayo we-hex angasetshenziselwa izinhlelo zokusebenza eziningi ezahlukene ezihlanganisa ukhuni oluqinile, insimbi, nezinye izinto zokwakha zamaphrojekthi anjengamadokhi, amabhuloho, izakhiwo zomgwaqo omkhulu, nezakhiwo.Amabhawodi asindayo we-hex anamakhanda afojiwe abuye asetshenziswe ngokujwayelekile njengamabhawodi okusetshenzwa anekhanda.
Amabhawodi asindayo esakhiwo se-hex ayisisekelo sohlu lwamabhawodi we-handan haosheng, ikakhulukazi i-astm a325, a490,DIN6914 adingeka kakhulu futhi asetshenziswe kumaphrojekthi wokwakha afana nomhubhe nebhuloho, ujantshi wesitimela, uwoyela negesi, kanye nemboni yamandla omoya.
Ibholidi Yesakhiwo Sensimbi
Ibholidi yesakhiwo sensimbi iwuhlobo lwebhawodi yamandla aphezulu, futhi iwuhlobo lwezingxenye ezijwayelekile.Ukusebenza kokuqinisa kungcono, kusetshenziselwa isakhiwo sensimbi, ubunjiniyela, ukuze umphumela wokubopha.Ngokwesakhiwo sensimbi esijwayelekile, amabhawodi esakhiwo sensimbi ayadingeka ukuba abe ngaphezu kwebanga lesi-8.8, kanye nebanga le-10.9 kanye nebanga le-12.9, konke okungamabhawodi esakhiwo sensimbi anamandla aphezulu.
Ibhawodi yesakhiwo sensimbi ihlukaniswe ngohlobo lwebhawudi lokushela elinamandla aphezulu kanye nebhawodi enkulu enezinhlangothi ezine eziqinile, ibholidi enkulu ene-hexagonal high-strength ingeyezinga eliphezulu lamandla esikulufu esijwayelekile, kanye nohlobo lwe-torsional shear high-strength bolt wukuthuthukiswa kwesikulufu esikhulu. Ibhawodi elinamandla amakhulu ama-hexagonal, ukuze kwakhiwe kangcono.
Ukwakhiwa kwamabhawodi esakhiwo sensimbi kufanele kuqiniswe kuqala bese kuqiniswa, futhi amabhawodi esakhiwo sensimbi adinga ukusebenzisa isikrufu sikagesi sohlobo lomthelela noma isikrufu sikagesi esishintshayo se-torque;Futhi okokugcina kokuqina kwesakhiwo sensimbi amabhawodi anezidingo eziqinile, ukuqina kokugcina kokuqina kwesakhiwo sensimbi sokugunda amabhawodi kumele kusetshenziswe isikrufu sikagesi se-torsional shear, ukuqina kokugcina kwesakhiwo sensimbi ye-torque kufanele kusebenzise uhlobo lwe-torsional wrench kagesi.
Ibhawodi enkulu yesakhiwo esiyihexagon iqukethe ibhawudi elilodwa, inadi elilodwa, namawasha amabili.
Amabhawodi amakhulu angamahexagon esakhiwo sensimbi.
Ibholidi yesakhiwo sensimbi ye-torsional shear iqukethe ibhawodi, inati kanye newasha.
