Xa abantu abaninzi besiva i'hupula, bacinga ibhola yomnyazi okanye amacici. Kumgca wethu womsebenzi, licandelo elinzima elithwala umthwalo, kwaye ngokungafihlisiyo, elijongelwa phantsi ngokungapheliyo. Ingcinga yokuba a ihupula yinto nje egobileyo yentsimbi kulapho iiprojekthi ezininzi ziqala ukuya emacaleni. Ndiyibonile i-specs eyiphatha njengengcinga yasemva, kuphela ukujongana neendlela zokusilela ezibuyela emva kuloo msesane ibukeka ilula. Akukho malunga nokumila; imalunga nefiziksi yelophu evaliweyo phantsi koxinzelelo, ukuhanjiswa koxinzelelo ukuba isangqa esigqibeleleyo-okanye rhoqo, i-ellipse eyenziwe ngobunjineli-ilawula. Ukuyenza ingalunganga kuthetha ukuba yonke into ebambiseneyo ayiphumelelanga.

Ijometri yoMnyanzelo

Iqala ngekhoyili. I-high-carbon steel wire, yondliwe, iqondiswe, inqunyulwe. Ukubunjwa kubonakala kuthe ngqo: gobela kwisangqa kwaye weld iziphelo. Kodwa ingxaki yokuqala ikhona. Ukuvalwa okugqibeleleyo kwe-360-degree kunye ne-butt weld kudala ukunyuka koxinzelelo olugxininisiweyo kwindawo ye-weld. Kwizicelo zomthwalo oguqukayo-cinga ngokukhusela iitarps ezinzima kwisixhobo sokomba okanye amaqhina olwakhiwo kucingo lwexeshana-leyo yimvelaphi yokuqhekeka kokudinwa. Oku sikufunde ngeembuyekezo, hayi ithiyori. Umthengi ekwarini wayelahlekelwa ihupula iziqhoboshi kumnatha wesikrini zigubungela inyanga nenyanga. Uhlalutyo lokungaphumeleli luhlala lubonisa ukuqhekeka okusasazeka kwi-weld.

Ukulungiswa bekungeyo-weld engcono, kodwa ukugqithelana okwahlukileyo. Ukutshintshela kwi-lap joint design, apho iziphelo ziwelana ngobubanzi bobubanzi phambi kwe-welding, isasaza umthwalo. Kubonakala ngathi yinkcukacha encinci, kodwa iyayitshintsha imo yokungaphumeleli ukusuka kwi-fracture ye-brittle ngokukhawuleza ukuya kwi-deformation ehambayo, ebonakalayo. Olu luhlobo lwenuance ongayifumaniyo kwincwadana yemigaqo. Ivela ekudilizeni iindawo ezingaphumelelanga kunye nokubona ibali kwingqolowa yentsimbi. Iinkampani ezisebenza ngokukhethekileyo kwimveliso yevolumu, njenge-Handan Zitai Fastener Manufacturing Co., Ltd., ziyakufumana oku.
