1.1 Ipulasitiki
I-Plasticity yikhono lensimbi yensimbi ukukhiqiza ukuguqulwa kwepulasitiki (ukuguqulwa okuhlala njalo) ngaphansi komthwalo ngaphandle kokulimala.
1.2 Ukuqina
Ukuqina kuyinkomba yezinga lokuqina noma ukuthamba kwensimbi eyinsimbi.Indlela evame ukusetshenziswa kakhulu yokunquma ubulukhuni ekukhiqizeni indlela yobulukhuni bokungena, esebenzisa i-indenter yejiyomethri ethile ukuze icindezele ebusweni bensimbi ehloliwe ngaphansi komthwalo othile futhi inquma ubulukhuni bayo ngokwezinga lokucindezelwa. kuyo.
Izindlela ezisetshenziswa kakhulu yiBrinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) kanye nezindlela ze-Vickers hardness (HV).
1.3 Ukukhathala
Amandla, ipulasitiki nobulukhuni okuxoxwe ngakho ngaphambili konke kuyizinkomba zezakhiwo zemishini yensimbi ngaphansi komthwalo ongashintshi.Eqinisweni, izingxenye eziningi zomshini zisebenza ngaphansi kwemithwalo ye-cyclic, futhi ngaphansi kwezimo ezinjalo izingxenye zikhiqiza ukukhathala.
1.4 Ukuqina komthelela
Umthwalo osebenza engxenyeni yomshini ngesivinini esikhulu ubizwa ngokuthi i- impact load, futhi ikhono lensimbi ukumelana nomonakalo ngaphansi komthwalo womthelela kubizwa ngokuthi ukuqina komthelela.
1.5 Amandla
Amandla ukumelana kwensimbi okonakaliswa (ukuguqulwa kwepulasitiki ngokweqile noma ukuphuka) ngaphansi komthwalo omile.Njengoba isenzo somthwalo ngesimo sokushuba, ukucindezelwa, ukugoba, ukugunda, ngakho amandla nawo ahlukaniswe abe amandla aqinile, amandla okucindezela, amandla okugoba, amandla okugunda, njll. Kuvame ukuba nokuxhumana okuthile phakathi kwamandla ahlukahlukene, ukusetshenziswa kwamandla okuqina ajwayelekile njengesikhombi samandla esiyisisekelo.
Ishubhu yesikwele isetshenziswa ekwakhiweni, ukukhiqizwa kwemishini, amaphrojekthi wokwakha insimbi, ukwakhiwa kwemikhumbi, ukwesekwa kokuphehla amandla elanga, ubunjiniyela besakhiwo sensimbi, ubunjiniyela bamandla, izimboni zamandla, imishini yezolimo neyamakhemikhali, izindonga zamakhethini engilazi, i-chassis yemoto, izikhumulo zezindiza, ukwakhiwa kukabhayela, izinsimbi zomgwaqo onguthelawayeka. , ukwakhiwa kwezindlu, imikhumbi yokucindezela, amathangi okugcina uphethiloli, amabhuloho, izinto zesiteshi samandla kagesi, imishini yokuphakamisa neyokuthutha kanye nezinye izingxenye zesakhiwo ezishiselwe umthwalo omkhulu, njll.
Ukuhlukaniswa kwenqubo
Ishubhu yesikwele ihlukaniswa ngokwenqubo yokukhiqiza: ishubhu lesikwele elishisayo eligoqiwe elingenamthungo, ishubhu lesikwele elidonswa ngokubanda elingenamthungo, ishubhu lesikwele elingaphandle nekhono, ishubhu lesikwele elishiselwe.
Phakathi kwabo, ashiselwe square tube ihlukaniswe yaba
1. ngokuya ngenqubo - i-arc welding square tube, ukumelana neshubhu yesikwele (imvamisa ephezulu, imvamisa ephansi), i-gas welding square tube, ishubhu yesikwele yokushisela isithando somlilo
2. ngokusho kwe-welding seam - i-seam eqondile ipayipi yesikwele ehlanganisiwe, ipayipi yesikwele esivunguzayo.
Ukuhlukaniswa kwezinto
Ipayipi lesikwele ngezinto ezibonakalayo: ipayipi eliyisikwele le-carbon steel elingenalutho, ipayipi eliyisikwele eliyingxubevange ephansi.
1. Plain carbon steel ihlukaniswe: Q195, Q215, Q235, SS400, 20# steel, 45# steel, njll.
2. Insimbi ye-alloy ephansi ihlukaniswe: Q345, 16Mn, Q390, ST52-3, njll.
Ukuhlukaniswa okujwayelekile kokukhiqiza
Ishubhu yesikwele ngokwezindinganiso zokukhiqiza: ishubhu yesikwele esijwayelekile sikazwelonke, ishubhu yesikwele esijwayelekile saseJapan, ishubhu yesikwele sombuso, ishubhu yesikwele esijwayelekile saseMelika, ishubhu yesikwele esijwayelekile saseYurophu, ishubhu yesikwele esingajwayelekile.
Ukuhlukaniswa komumo wesigaba
Ishubhu yesikwele ngokuya ngesimo sokuhlukaniswa kwesigaba.
1. I-tube yesikwele yesigaba esilula: ithubhu yesikwele yesikwele, ishubhu yesikwele esingunxande.
2. Ishubhu yesikwele yesigaba esiyinkimbinkimbi: ishubhu lesikwele sembali, ishubhu lesikwele esivulekile, ishubhu lesikwele sikathayela, ishubhu lesikwele elimise okwesikwele.
Ukuhlukaniswa kokwelashwa kwendawo
Ishubhu yesikwele ngokuya ngokwelashwa kwendawo: ishubhu lesikwele elishisayo, ishubhu lesikwele elayisikwele se-electro galvanized, ishubhu yesikwele esigcotshwe ngamafutha, ishubhu lesikwele esifakwe emanzini anosawoti.
Sebenzisa ukuhlukanisa
Ishubhu yesikwele ngokufaka isicelo: ishubhu yesikwele yokuhlobisa, ithuluzi lomshini ishubhu yesikwele, ishubhu yesikwele yemboni yemishini, ishubhu yesikwele yamakhemikhali, isakhiwo sensimbi ishubhu yesikwele, ishubhu lesikwele sokwakha umkhumbi, ishubhu yesikwele yezimoto, ishubhu lesikwele sensimbi, ishubhu yesikwele esinjongo ekhethekile.
Ukuhlukaniswa kobukhulu bodonga
Ishubhu yesikwele ihlukaniswa ngokuqina kodonga: ishubhu lesikwele sodonga oluwugqinsi, ishubhu lesikwele sodonga oluncane kanye neshubhu lesikwele sodonga oluncane.
