Uthini umahluko phakathi kokuphosa kunye nokwenza?

Zininzi iinkqubo ezinamagama afanayo kwishishini, kodwa kukho umahluko omkhulu phakathi kwazo, njengokuphosa kunye nokwenza.

Intshayelelo yokuphosa kunye nokukhwabanisa

Ukuphosa: isinyithi esinyibilikisiweyo solwelo sigcwalisa umngxuma wokungunda ukuze uphole, kwaye imingxuma yomoya iyenzeka ngokulula embindini waloo malungu; Fudumeza kwaye unyibilikise isinyithi kwaye ugalele kwi-mold yesanti okanye i-mold. Emva kokupholisa, kuya kuqina kwisitya.
Ukuqulunqa: Ikakhulu yenziwa yi-extrusion kwiqondo lokushisa eliphezulu, elinokuthi licokise iinkozo kwiindawo. Izinto zetsimbi kwimeko yeplastiki zinokuguqulwa zibe ngumsebenzi onomlo othile kunye nobukhulu ngokubethelwa kunye nezinye iindlela, kunye neempawu zayo ezibonakalayo zingatshintshwa.

Umahluko phakathi kokuphosa kunye nokwenza

1. Iinkqubo ezahlukeneyo zokuvelisa

Ukusasa kukwenza kanye. Emva kokuba isinyithi inyibilika ibe yi-liquid, igalelwe kwi-cavity ye-casting ehambelana nesimo senxalenye, kwaye emva koko ipholile, iqiniswe kwaye ihlambuluke, ukuze ifumane indlela yokucubungula yamacandelo okanye i-burrs. I-specialty casting igxile kwinkqubo yokunyibilika kwesinyithi kunye nolawulo lwenkqubo kwinkqubo yokuphosa.
Ukubunjwa kucotha ukwenza. Umatshini wokubumba usetyenziselwa ukufaka uxinzelelo kwintsimbi yentsimbi, ukukhama, isando kunye nezinye iindlela zokwenza izinto zetsimbi kwimeko yeplastiki ibe yindlela yokucubungula kunye nesimo esithile kunye nobukhulu bomsebenzi. Ukuqulunqa yiplastiki eyenza phantsi kwemeko eqinileyo, enokuthi yohlulwe ibe yinkqubo eshushu kunye nokusebenza okubandayo, okufana nomzobo we-extrusion, i-pier roughening, i-punching, njl.

2. Ukusetyenziswa okwahlukeneyo

Ukubumba ngokuqhelekileyo kusetyenziselwa ukusetyenzwa kwe-forgings kunye nemilo ethile kunye nobukhulu. Ukusasa yindlela yoqoqosho ngokwentelekiso yokwenza iziphene ezirhabaxa, kwaye isetyenziswa ngokubanzi kwiindawo ezinemilo entsonkothileyo.

3. Iingenelo ezahlukeneyo

Izibonelelo zokwenziwa:

Ukuqulunqa kunokuphelisa iziphene ezifana ne-porosity-cast eveliswa kwinkqubo yokunyibilikisa kwesinyithi, kwandisa i-microstructure. Ngexesha elifanayo, ngenxa yokuba umgca wokuhamba kwesinyithi opheleleyo ugciniwe, iipropati ze-mechanical ofgings ngokuqhelekileyo zingcono kunezo zokuphoswa kwezinto ezifanayo. Kwiindawo ezibalulekileyo ezinomthwalo ophezulu kunye neemeko zokusebenza ezinzima kumatshini ochaphazelekayo, iifogi zisetyenziswa kakhulu ngaphandle kweepleyiti, iiprofayili okanye ii-weldments ezinemilo elula enokuthi ifakwe.
Ukusasaza okuluncedo:

1. Inokuvelisa iinxalenye ezinemilo enzima, ngakumbi iindawo ezingenanto ezinemingxuma yangaphakathi enzima.

2. Ukuguquguquka okubanzi. Izinto zetsimbi ezisetyenziswa ngokuqhelekileyo kwishishini zingaphoswa, ukusuka kwiigram ezimbalwa ukuya kumakhulu eetoni.

3. Umthombo obanzi wezinto eziluhlaza kunye nexabiso eliphantsi, njengentsimbi ye-scrap, iinxalenye ze-scrap, ii-chips, njl.

4. Ubume kunye nobukhulu bokubunjwa busondele kakhulu kumacandelo, okunciphisa inani lokusika kwaye lilungu le-processing non-cutting process.

5. Isetyenziswa ngokubanzi. I-40% ~ 70% yoomatshini bezolimo kunye ne-70% ~ 80% yezixhobo zoomatshini zi-castings.

4. Izinto ezingeloncedo zahlukile

Forging defect: Kwimveliso yokwenziwa, kulula ukubangela iingozi zokwenzakala
Ukuphosa iziphene:

1. Iimpawu zoomatshini zingaphantsi kwi-forgings, njengesakhiwo esinqabileyo kunye neziphene ezininzi.

2. Kwisanti yokuphosa, isiqwenga esinye, imveliso yebhetshi encinci kunye noxinzelelo olukhulu lwabasebenzi.

3. Umgangatho wokuphosa awuzinzile, kukho iinkqubo ezininzi, izinto ezichaphazelayo zinzima, kwaye ezininzi iziphene ziyenzeka ngokulula.
