Ubona i-HT250 emdwebeni, futhi kulula ukucabanga ukuthi enye nje insimbi empunga. Izinto ezijwayelekile. Kodwa yilapho izinkinga eziningi ziqala khona—kucatshangwa ukuthi yimpahla. Eminyakeni yami ngisebenzelana nokusakazwa, kusukela ekutholeni izinto kuye ekwenzeni imishini yokugcina, ngithole ukuthi i-HT250 iwumsebenzi ochazwa inqubo yayo njengokwakheka kwayo. I-'HT' imele i-grey cast iron, futhi i-'250' ingamandla amancane okudonsa ku-MPa. Kuzwakala kuqondile, kodwa ukushaya lokho okungu-250 ngokungaguquki, ingxenye nengxenye, ikakhulukazi kumajiyometri ayinkimbinkimbi noma izingxenye ezinezindonga ezincane, yilapho ikhono lomsunguli lihlukana khona nalo lonke. Akukhona nje ngokuncibilikisa insimbi; imayelana nokulawula ukwakheka kwe-graphite flake, amazinga okupholisa, nokulawula ukucindezeleka okungokwemvelo. Ngibone amaphrojekthi amaningi kakhulu ekhubeka ngoba othile uphathe i-spec njengento elula ye-oda lokuthenga ngaphandle kokuqonda ukuthi yini engemuva kwayo.
I-Foundry Floor Reality
Uma sikhuluma nge-HT250 nge-Foundry efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ingxoxo iqala ukusebenza ngokushesha. Iminyaka yabo engamashumi amathathu kugobolondo kanye nokutshala imali kusho ukuthi bathele insimbi eningi. Into yokuqala abazoyibuza akukhona nje mayelana nebanga; imayelana nomsebenzi wengxenye, ukuhluka kokuqina kodonga, nalapho izindawo ezinokucindezeleka okukhulu zikhona. Isibonelo, umzimba we-valve kanye nendlu yegiya kungase kubize kokubili HT250, kodwa isistimu yokugenca kanye nomklamo wesikhuphukeli kungase kwehluke ngokuphelele ukuze kuqinisekiswe ukuzwakala ezindaweni ezibucayi. Ngokusakazwa kwesikhunta segobolondo, i-QSY egxile kukho, uthola ukuqedwa okungcono kwendawo kanye nokunemba kobukhulu uma kuqhathaniswa nesihlabathi esiluhlaza, kodwa futhi siqina ngokushesha. Lokho kuyinkemba esika nhlangothi zombili HT250—ingacwengisa ukwakheka kwe-graphite, elungele amandla, kodwa uma ingalawulwa, ingakhuthaza ukugodola (ukwenza insimbi emhlophe, ephukayo) ezingxenyeni ezincane noma emakhoneni acijile.
Ngikhumbula inqwaba yabakaki bepompo esasiyenzile eminyakeni embalwa edlule. Umdwebo ucacisiwe HT250, futhi amasampula aphumelele ukuhlolwa kwe-tensile. Kodwa ensimini, amayunithi amaningana ahlakulela imifantu eduze nezimbobo ezikhulayo. Ukuhlaziywa kokwehluleka kukhomba izindawo ezenziwe zasendaweni zokuqukethwe okuphezulu kwe-carbide—empeleni, amachashaza ensimbi ebandayo—lapho kwaklanywa khona ikhona elicijile langaphakathi. I-Foundry yayiphuthelwe ngenxa yokuthi ikhuphoni lokuhlola elivela ohlelweni lomgijimi libonise izakhiwo eziphelele. Siyini isifundo? Impahla yempahla iyisilinganiso; ukwehluleka kwenzeka endaweni ebuthakathaka kakhulu. Kwakudingeka sisebenze ne-Foundry ukuze siguqule umklamo nge-fillet enkulu futhi silungise ukunamathela kwesikhunta ukuze sibambezele ukupholisa kuleyo ndawo ethile. Kwakungelona ushintsho ebangeni lezinto ezibonakalayo; bekuwushintsho endleleni esifinyelele ngayo kuleyo geometry ethile.
Kulapho okuhlangenwe nakho kozakwethu kubonisa khona. Isikhungo esisanda kugcwalisa i-oda ngabe sisola umklamo wethu. I-technical foundry ibandakanyeka enkingeni. Uma ubheka iphothifoliyo ye-QSY ku-tsingtaocnc.com, ungabona baphatha ububanzi ukusuka kokulula kuya kokulingisa okuyinkimbinkimbi.
