Njira ndi zofunikira zaumisiri zopangira ma bolts amphamvu kwambiri

1. Kusankha zinthu
Chitsulo cha kaboni chili ndi makina abwino kwambiri, chimatha kukumana ndi mitundu yosiyanasiyana ya mphamvu zophatikizira, ndipo chimakhala ndi mtengo wotsika poyerekeza ndi zida zina zomangira.
The makina katundu wa carbon zitsulo ndi tcheru ku carbon content, amene nthawi zambiri pansi 1.0%. Nthawi zambiri timasiyanitsa chitsulo chochepa cha carbon (C% ≤ 0,25%), sing'anga mpweya zitsulo (0,25% 0.45%), ndi aloyi zitsulo (kuwonjezera zinthu alloying kuti mpweya zitsulo wamba) zochokera mpweya zili mu carbon zitsulo chuma.
2. Spheroidization (kufewetsa) annealing
(1) Pamene spheroidized (kufewetsa) annealed countersunk mutu zomangira ndi hexagonal cylindrical mutu mabawuti amapangidwa pogwiritsa ntchito ukadaulo wa mutu ozizira, kapangidwe koyambirira kwachitsulo kumakhudza mwachindunji luso lopanga panthawi yozizira. Pakuzizira mutu ndondomeko, mapindikidwe pulasitiki m'madera m'dera akhoza kufika 60% -80%. Chifukwa chake, ndikofunikira kuti chitsulocho chizikhala ndi pulasitiki yabwino.
(2) Pakuti sing'anga mpweya zitsulo ndi sing'anga mpweya aloyi zitsulo ndi kuchuluka kwazomangira zamphamvu kwambiri, spheroidization (kufewetsa) annealing ayenera kuchitidwa pamaso kuzizira mutu kupeza yunifolomu ndi zabwino spheroidized pearlite, kuti akwaniritse bwino ntchito zofunika kupanga.
3. Kujambula kwawaya
Tambasulani chimbalecho ndikugwiritsa ntchito mphamvu yokoka yofananirako kuti mukwaniritse ma waya omwe amafunikira (ie m'mimba mwake) popanga.
Magawo okhazikika a waya amitundu yambiri yozungulira muzitsulo zazitsulo ndi M8, M10, M12, M16, ndi zina zotero. Sangagwiritsidwe ntchito mwachindunji kupanga bawuti. Mwachitsanzo, kupanga bawuti ya 10mm yokhala ndi ulusi wokwanira kumafuna kukoka m'mimba mwake mpaka 8.78 + 0.04mm, pomwe kupanga bawuti ya 16mm kumafuna waya awiri a 14.38 + 0.02mm.
4.Kuzizira kozizira
Kupanga kwa hex bawutimutu utenga ozizira forging processing pulasitiki. Poyerekeza ndi kudula processing, zitsulo CHIKWANGWANI (zitsulo waya) mosalekeza pamodzi mankhwala mawonekedwe popanda kudula pakati, motero kuwongolera mankhwala mphamvu ndi kupeza kwambiri mawotchi katundu. Kupanga mitu yozizira kumaphatikizapo kudula ndi kupanga, single station click single, dinani kawiri mutu ozizira, ndi ma multi station automatic ozizira mutu.
6. Kukonza ulusi
Ulusi wa bolt nthawi zambiri umakonzedwa ndi kuzizira, momwe ulusi wopanda kanthu mkati mwa m'mimba mwake umatikita (kugudubuzika) ndi screw plate (kufa), ndipo ulusiwo umapangidwa ndi kukakamiza kwa screw plate (rolling die). Mtsinje wa pulasitiki wa gawo lopangidwa ndi ulusi ukhoza kupezedwa popanda kudulidwa, zomwe zimapangitsa kuti pakhale mphamvu zowonjezera, zolondola kwambiri, komanso khalidwe lofanana la mankhwala, omwe amagwiritsidwa ntchito kwambiri.
Chodziwika bwino pakugudubuza (kusisita) kukonza ulusi ndikuti kuthamanga sikuyenera kukhala kokwera kwambiri. Ngati ndipamwamba kwambiri, mphamvuyo imakhala yochepa ndipo pamwamba pa mano a ulusi amatha kupatukana kapena kusanja ulusi. M'malo mwake, ngati chiwerengero cha zosintha ndi otsika kwambiri, m'mimba mwake ulusi sachedwa kutaya roundness, ndi kukakamiza koyamba pa anagubuduza kumawonjezeka abnormal, chifukwa cha kufupikitsa nkhungu moyo.
7. Chithandizo cha kutentha
Kutentha mankhwalazomangira zamphamvu kwambiriAyenera kulandira chithandizo chozimitsira ndi kutenthetsa molingana ndi zofunikira zaukadaulo kuti apititse patsogolo mawonekedwe amakanika a zomangira ndikukwaniritsa zomwe zatchulidwa zamphamvu zamakomedwe komanso kuchuluka kwa zokolola.
Chifukwa cha kuchuluka kwakukulu kwa kupanga ndi mtengo wotsika wa mabawuti amphamvu kwambiri, komanso mawonekedwe osavuta komanso olondola a gawo lopangidwa ndi ulusi, pamafunika kuti zida zochizira kutentha ziyenera kukhala zogwirizana kwambiri ndi kupanga, kuchuluka kwa automation, komanso kutentha kwambiri kwamankhwala. Kuti mupange zomangira zamphamvu kwambiri, zida zamakono zochizira kutentha ndizofunikira kwambiri.
