Bolt kuyinto evamile izingxenye mechanical, evame ukusetshenziswa ezindaweni eziningi, kuba by ikhanda bese isikulufa izingxenye ezimbili iqembu fasteners, kudingeka isetshenziswe ngokuhlanganyela nati, ikakhulukazi esetshenziswa ukubophela uxhumano izingxenye ezimbili nge ngokusebenzisa izimbobo. Mhlawumbe awunakho ukuqonda kwezinto zebanga lebhawodi, lesi sihloko sizokwethula kumpahla yebhawodi, ulwazi oluhlobene nebanga, ukuze uvumele abantu abaningi bafunde ukukhomba lezi zakhiwo ezincane zebhawodi.
Amabanga nezinto zokwakha zamabhawodi zibhekisa kuphi?
Ibanga le-bolt libhekise kwibhawodi lithi 4.8grade, 8.8 grade, 10.9 grade kanye nelinye ibanga lebhawodi.
I-Material ibhekisela ku-bolt eyenziwe ngezinto ezibonakalayo, njenge-Q235, 35K, 40Cr, 45 # steel, 35CrMo steel, 304 insimbi engagqwali kanye ne-316 insimbi engagqwali nokunye.
Ibanga le-bolt nezinto ezibonakalayo ubuhlobo obuthile, insimbi emnene ingakhiqiza kuphela amabhawodi ebanga lamandla aphansi, insimbi ye-carbon ephakathi ingakhiqiza amabhawodi ebanga lamandla aphakathi, insimbi ephezulu ye-carbon, insimbi ye-alloy ingakhiqiza amabhawodi ebanga lamandla aphezulu. Ibanga elithile lebhawodi licacisa ukwakheka kwamakhemikhali okuhambisanayo kanye nezakhiwo zemishini, kodwa futhi nokunquma okokusebenza.
Nalu uhlu amamaki ezivamile bolts kungaba yini impahla. Izinga le-4.8 lingaba yi-Q235, i-Q195 nezinye izinto zensimbi ezithambile. I-5.8 level Q235 ngaphezu kwazo zonke izinto ezingaba, azidingi ukwelashwa okushisa. I-8.8 yentambo ububanzi obuyi-16MM noma ngaphansi, 35 # ukwelashwa kokushisa okushisa, 16mm noma ngaphezulu, 45 # kanye ne-low carbon alloy steel tempering. Izinga le-10.9 lensimbi ye-medium-carbon alloy tempering Ukwelashwa kokushisa 35Crmo 40Cr nokunye.
Ingabe amabhawodi anamandla angahlukaniswa namabhawodi ajwayelekile ngezinto zawo?
Ngokujwayelekile ihlukaniswe ngokwezinga lamandla.
Izinga lokusebenza kwe-Bolt 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 njalonjalo emabangeni angaphezu kwe-10, okungama-8.8 nangaphezulu amabhawodi enziwe ngensimbi ye-low-carbon alloy noma i-medium-carbon steel kanye ne-heat-treated (icime, eyaziwa ngokuthi i-high-tempered, i-tomate eyaziwa ngokuthi ngokuvamile eyaziwa ngokuthi amabhawudi ezivamile. Ukulebula kwezinga lokusebenza kwe-Bolt kunezingxenye ezimbili zokwakheka kwedijithali, ngokulandelanayo, amandla aqinile okuzisholo yenani lempahla yebhawodi kanye nenani lesilinganiso samandla aguquguqukayo.
Isibonelo, izinga lokusebenza grade 8.8 amabhawudi, incazelo ithi:
1, umshudo amandla okuzisholo okuqinile wezinga le-800MPa;
2, isilinganiso samandla we-bolt siveza amandla angu-0.8;
3, amandla okuzisholo okukhiqiza wento yebhawodi afika ku-800 × 0.8 = 640MPa izinga lamabhawodi anamandla aphezulu asetshenziswa kakhulu ezingeni le-8.8 nele-10.9, amabhawodi ajwayelekile asetshenziswa kakhulu ezingeni le-4.8.
