Chitoliro chachitsulo chosasunthika chili ndi gawo lopanda kanthu ndipo chimagwiritsidwa ntchito mochuluka ngati payipi yonyamulira madzi, monga mapaipi otengera mafuta, gasi, gasi, madzi ndi zinthu zina zolimba.Chitoliro chachitsulo ndi zitsulo zozungulira ndi zitsulo zina zolimba, poyerekeza ndi kupindika komweku ndi mphamvu ya torsion, kulemera kwake, ndi chitsulo chapakati pazachuma, chomwe chimagwiritsidwa ntchito kwambiri popanga zigawo zamakina ndi zamakina, monga ndodo zobowola mafuta, zitsulo zamagalimoto. , mafelemu njinga ndi kumanga zitsulo scaffolding ntchito popanga mbali zitsulo chitoliro mphete, akhoza kusintha magwiritsidwe zinthu, kuphweka njira kupanga, kupulumutsa zipangizo ndi nthawi processing, wakhala ankagwiritsa ntchito popanga zitsulo chitoliro.
Zimango katundu
Chitsulo makina katundu ndi kuonetsetsa kuti zitsulo mapeto ntchito katundu (mawotchi katundu) wa zizindikiro zofunika, zimadalira mankhwala zikuchokera zitsulo ndi dongosolo kutentha mankhwala.Muyeso wazitsulo zachitsulo, malingana ndi zofunikira zosiyanasiyana zogwiritsira ntchito, tchulani mphamvu zowonongeka (mphamvu zolimbitsa thupi, mphamvu zokolola kapena zokolola, elongation) ndi kuuma, zizindikiro zolimba, pali zofunikira za wogwiritsa ntchito kutentha kwakukulu ndi kutsika, etc.
① Kulimba kwamphamvu (σb)
Chitsanzo mu kukanikizana, mphamvu yaikulu (Fb) inapirira panthawi yokoka, yogawidwa ndi kupsinjika (σ) komwe kumachokera kumalo oyambirira a gawo (So) la chitsanzo, chotchedwa tensile mphamvu (σb), unit ndi N/mm2 (MPa).Zimayimira mphamvu yochuluka yazitsulo zachitsulo kuti zisawonongeke zowonongeka.Njira yowerengera ndi
Kumeneko: Fb - mphamvu yayikulu yotsatiridwa ndi chitsanzo pamene imakoka, N (Newton);Chifukwa chake - gawo loyambirira lachitsanzo, mm2.
②Zokolola (σs)
Ndi zochitika zokolola zazitsulo zachitsulo, chitsanzo mu njira yotambasula ya mphamvu sichikuwonjezeka (kukhalabe nthawi zonse) chikhoza kupitiriza kukulitsa kupanikizika, komwe kumatchedwa zokolola.Ngati kugwa kwamphamvu kukuchitika, kusiyana kuyenera kupangidwa pakati pa zokolola zapamwamba ndi zotsika.Gawo la zokolola ndi N/mm2 (MPa).
Zokolola zapamwamba (σsu): kupsyinjika kwakukulu pamaso pa chitsanzocho chisanayambe ndipo mphamvu imayamba kugwa;zokolola zotsika (σsl): kupanikizika kochepa mu gawo lopereka pamene zotsatira zoyamba zosakhalitsa sizikuganiziridwa.
Njira yowerengera zokolola ndi: chilinganizo: Fs - mphamvu yokolola (yokhazikika) panthawi yokhazikika ya chitsanzo, N (Newton) Kotero - gawo loyambirira la gawo la chitsanzo, mm2.
③ Kutalikitsa pambuyo popuma (σ)
Pakuyesa kwamphamvu, kuchuluka kwa kuchuluka kwa utali wa chithunzicho chikakokedwa kuchokera pachizindikiro chake mpaka kutalika kwa chizindikiro choyambirira kumatchedwa elongation.Imawonetsedwa ngati σ mu%.Kuwerengeredwa monga: chilinganizo: L1 - kutalika kwa chitsanzo pambuyo pochotsa chizindikiro chake, mm;L0 - kutalika kwa chizindikiro choyambirira cha chitsanzo, mm.
④ Kuchepa kwapang'onopang'ono (ψ)
Pakuyesa kwamphamvu, kutsika kwakukulu kwa gawo la gawo lachitsanzo pakuchepa kwake pambuyo potuluka ngati gawo la gawo loyambira lomwe limatchedwa gawo locheperako.Amawonetsedwa ngati ψ mu %.Njira yowerengera ili motere
Kumene: S0 - gawo loyambirira lachitsanzo, mm2;S1 - malo ocheperako pang'onopang'ono pa shrinkage pambuyo pochotsa chitsanzocho, mm2.
⑤ Kuuma index
Kukhoza kwachitsulo kukana kulowetsa chinthu cholimba pamwamba, chotchedwa kuuma.Kutengera njira yoyesera komanso kuchuluka kwa ntchito, kuuma kumatha kugawidwa mu kuuma kwa Brinell, kulimba kwa Rockwell, kulimba kwa Vickers, kulimba kwa m'mphepete mwa nyanja, kulimba kwapang'ono komanso kuuma kwa kutentha kwambiri.Pakuti chubu nthawi zambiri amagwiritsidwa ntchito kukhala ndi Brinell, Rockwell, Vickers kuuma katatu.
Shandong Xinjie Metal Equipment Co., Ltd. ndi kampani zitsulo chitoliro kaphatikizidwe kupanga, processing ndi ntchito, makamaka chinkhoswe: chosakanizika zitsulo chitoliro (wandiweya-mipanda msokonezo chitoliro, otsika ndi sing'anga kuthamanga kukatentha chubu, aloyi zitsulo chitoliro, lalikulu mphindi chitoliro , chubu chotenthetsera chapamwamba, chitoliro chophwanyika cha petroleum, chitoliro cha feteleza, chitoliro chapadera chachitsulo), chitsulo chosapanga dzimbiri (chitoliro chosapanga chitsulo chosapanga dzimbiri, chitoliro chosapanga dzimbiri, chitoliro chosapanga dzimbiri, chitoliro chachitsulo/mbale, chitsulo chosapanga dzimbiri chozungulira, chitsulo chosapanga dzimbiri square mphindi chitoliro), zosapanga dzimbiri Mbiri (I-mtengo, zitsulo ngodya, chitsulo njira) ndi zinthu zina.
