Sihamba phambili ekuletheni{0}}ikhwalithi ephezulu OEM kanye ODMizixazululo zozakwethu,
inikwe amandla-ngobuchwepheshe obuphambili kanye nobungcweti bokukhiqiza obukhulayo.
Yenziwe ngensimbi-yekhabhoni ephezulu (1022 noma 1018 steel) ngokusebenzisa ukwakheka kwesihloko esibandayo, ngemicu eklanywe njengamazinyo kanxantathu abukhali noma amazinyo ohlobo A{3}}azithephayo. Ingathepha ngokuqondile izintambo kuma-substrates afana namashidi ensimbi azacile, amapulasitiki, nokhuni ngaphandle{5}}izimbobo ezibhoboziwe ngaphambili, futhi isetshenziswa kakhulu kuzinto zikagesi ezijwayelekile zaseNyakatho Melika, izinto zikagesi zasendlini, imishini enembile, nezinye izikulufu. Ukuthi ukuvikela ama-PCB emishinini kagesi, ukulungisa imicu yokuhlobisa efenisha, noma ukuhlanganisa abakaki bensimbi abancane, izici zayo zesakhiwo nokukhethwa kwezinto ezibonakalayo kungahlangabezana nezidingo ezihlukahlukene.
Yini ehlanganisa izikulufi ezifanelekayo zokuzithinta 8-32? Imingcele yekhwalithi engukhiye ingamandla aqinile namandla okugunda. Amandla aqinile asho ikhono lokumelana nokuphuka lapho ehlukaniswa, kuyilapho amandla okugunda abhekisela emandleni okumelana nokuphuka ngaphansi komthwalo ophambene. Kokubili kunquma ngokuqondile ukuthembeka kwesikulufa ngemva kokuqiniswa.
Amandla okuqina ahlobene eduze nokukhethwa kwezinto. Sisebenzisa insimbi engu-1022 ephezulu{2}yekhabhoni ekukhiqizeni izikulufu zokuzithepha 8-32. Ngemva kokucisha, ubulukhuni be-screw shaft bufinyelela ku-HRC25-32, kuzuza ibhalansi yamandla nokuqina. Amandla aqinile afinyelela ku-Greater noma alingana no-600MPa, ahlangabezana nezidingo zokubopha umthwalo wokukhanya wemishini enembayo.
Ukuze uthole amandla athuthukisiwe nokumelana nokugqwala, i-1022 high{1}carbon steel ingafakwa uthayela. Izinqubo ezijwayelekile zokufaka uthayela zihlanganisa i-electroplating kanye ne-hot-dip galvanizing, kanye ne-nickel plating kanye ne-phosphating. Ukumelana nesifutho sikasawoti Kukhulu noma kulingana namahora angu-24 (okufakwe amagalani) futhi Kukhulu noma kulingana namahora angu-48 (i-nickel-ecwetshiwe), okuyenza ifaneleke kokubili indawo yasendlini eyomile neswakeme kancane.
Intambo idlala indima ebaluleke kakhulu ekusetshenzisweni kwayo yonke i-self tapping screws 8-32. Amandla okuqiniswa okunembayo ochungechunge oluhle ahlobene eduze nezici zentambo:
Izici zochungechunge
Umklamo omuhle-onemicu engu-32 iyintshi ngayinye uphumela ku-pitch yentambo engu-0.794mm kuphela. Ngemva kokuthepha, ukusebenzelana ne-substrate kuyaqina, futhi ukusebenza{4}}okuxegayo kungcono kunezikulufu{5}}ezimahhadla (amathuba okuxega endaweni edlidlizayo anciphe ngo-40%).
Ama-substrates afanelekile
Ifaneleka ngokukhethekile amashidi ensimbi azacile (njengamapuleti ensimbi, ama-alloys e-aluminium) anogqinsi olungu-1-3mm, amapulasitiki aqinile (ABS, PC), kanye nokhuni oluminyaniswe kakhulu. Inani elincane lokusika ngesikhathi sokuthepha ligwema ukuqhekeka kwe-substrate.
Ukuqina kwe-Meshing
Kwezinye{0}izimo ezinembayo eziphezulu, kunezidingo zokunemba okuphezulu kwezikulufa zokuzithepha 8-32. Akumele zixege ngenxa yokuvunyelwa ngokweqile, noma zikhulise ithoshi yokufaka ngenxa yokuphazamiseka okukhulu. Ngakho-ke, ngesikhathi sokukhiqiza, izidingo eziqinile zokubekezelelana ziyabekwa, ngokuvamile ngokuphambuka kwe-± 0.03mm, kuyilapho kuqinisekiswa ukuzinza ngesikhathi sokusetshenziswa.
Izikulufu zokuzithepha 8-32, ezigxile "ekunembile{2}}ekucushweni okuhle nokuguquguquka okujwayelekile", iyisibopheli esijwayelekile sezimo zokubopha ukulayisha okukhanyayo ohlelweni lombuso. Ukusebenza kwayo okuzinzile kanye nokuguquguquka okubanzi kuyenza ingenakuthathelwa indawo emkhakheni wokukhiqiza okunembayo.
Amashadi ashisayo: izikulufi zokuzidonsa 8-32, izikulufa zaseChina zokuzidonsa 8-32 abakhiqizi, abahlinzeki, imboni
