Intshayelelo yeHexagon head bolt

Ibhonti yeHexagon ibhekisa kwisibophelelo esenziwe yintloko kunye nesikrufu. Ibholithi yahlulwe yaba yibholithi yentsimbi kunye nentsimbi engatyiwayo ngokwezinto eziphathekayo, ezizezi,ibhonti yehexagon-entloko (inxalenye yomsonto)– iBanga C kunyeibhonti yehexagon-entloko (umsonto ogcweleyo)– iBanga C

Iinkqubo yokuqhubayeiibholiti zehexagonimi ngolu hlobo lulandelayo:

I-1, Sika, sebenzisa isikere esikhethekileyo ukusika izinto ezixingayo kwi-shear mold kwizithuba esizifunayo kwicala elinye.

I-2, i-punch yokuqala, eli nyathelo kukucinezela okungenanto kunye ne-punch yangasemva ngokuchasene ne-punch engenanto, kwaye emva koko utyhale okungenanto emva kokwenza ngokucothayo.

3, Ukubetha okwesibini, okufana neli nyathelo lingasentla, kukuphumeza isibini esikhulu sokufa kunye nokufa kwe-extrusion, ukuze into engenanto ibe yi-oblate emva kokucubungula.

I-4, Ukubethelwa kathathu, okwesithathu ukucubungula kunye nokubetha i-mold, isebenzisa i-hexagonal ye-punch die core ukusika. Xa intloko ene-hexagonal ye-raw material yenziwa kancinane, i-raw material ityhalwa kwi-mold okwesihlandlo sesithathu ukubethelela ukubumba. Ekugqibeleni, xa intloko ye-hexagonal inqunyulwa, imveliso igqityiwe.

Inqanaba lokusebenza

Umgangatho wokusebenza kweebholiti ezisetyenziselwa uxhulumaniso lwesakhiwo sensimbi luhlukaniswe ngaphezu kwe-10amabakala, kuquka 4.6, 4.8, 5.6, 6.8, 8.8.10.9, 12.9,njl. Phakathi kwabo,iibholithi zebanga lesi-8.8kwaye ngasentla zenziwe ngentsimbi ephantsi ye-carbon alloy okanye i-medium carbon steel kunye nokuphathwa kobushushu (ukucima kunye nobushushu), ezibizwa ngokuba yi-bolts high-power bolts, kwaye ezinye zibizwa ngokuba ziibholiti eziqhelekileyo. Amanqaku omgangatho wokusebenza webholithi aneenxalenye ezimbini zamanani, ezimele ngokulandelelanayo ixabiso lamandla okuqina kunye nomlinganiselo wamandla esivuno semathiriyeli yebholithi. Umzekelo:

Iibholithi ezinomgangatho wokusebenza we-4.6 zithetha:

1. Amandla okuzinza okubizwa ngokuba yi-bolt material afikelela kuma-400MPa;

2. Umlinganiselo wamandla esivuno sezinto zebholithi ngu-0.6;

3. Amandla emveliso yebhoti afikelela kuma-400 × 0.6=240MPa

Iibholiti eziphakamileyo ezinomgangatho wokusebenza we-10.9 zinokufikelela koku kulandelayo emva konyango lobushushu:

1. Amandla okuzinza okubizwa ngokuba yi-bolt material afikelela kwi-1000MPa;

2. Umlinganiselo wamandla esivuno sezinto zebholithi ngu-0.9;

3. Amandla emveliso yebholithi afikelela kwi-1000 × 0.9=900MPa kwinqanaba

Intsingiselo yomgangatho wokusebenza kwebholithi ngumgangatho wamazwe ngamazwe. Ukusebenza kweebholiti ezinebakala elifanayo lokusebenza kuyafana kungakhathaliseki ukuba zithini na kunye nendawo yemvelaphi. Kuphela ibakala lokusebenza elinokuthi likhethwe kuyilo.

Umzi-mveliso wethuikakhulu imvelisoiibholiti zehex ezinamandla aphezulu,hex nuts,B7 intonga enentambokunye 20 iminyaka imbali. Sihlala eNingbo, kwiphondo laseZhejiang, eTshayina.
