Cold akakungurusa simbi: hunhu, features, kushanda

Cold akakungurusa simbi (s / a) - mumwe zvikuru nevanhu mhando ano simbi-roll. Uwandu kugadzirwa simbi pepa iri akaramba achiwedzera vhoriyamu. Anogadzirwa sezvo zita rinoreva, nzira chando rinopfungaira. Ductile simbi inokurukurwa pedyo kumanikidzwa chinokosha pasina preheating. Inowanika maviri siyana - a Pepa chando-akakungurutsirwa uye mabhanzi. Finished zvigadzirwa anogona kunosiyana paurefu uye hukuru, pamwe akavezwa unopinza pamwe compression.

Zvinoitwa chando-anokungurutsirwa simbi

Kuwedzera Kudiwa chando-anokungurutsirwa simbi nokuda dzakakwirira unhu unhu kupfuura inopisa yakanyikwa chigadzirwa. Uyezve, jira simbi Ukobvu 1 mm uye zvishoma zvemari noitika chete chando muitiro. Cold rinopfungaira iri pasi kwakajairika kabhoni, yepamusoro kabhoni, yakapambadzirwa uye mukuru-chiwanikwa steels, ngura nemishonga, kupisa nemishonga uye nokupisa nemishonga alloys. Makemikari anoumba kubatwa simbi inosarudza ehupfumi ari simbi uye kusvika pamwero kwayo dzose. Saka, nokuti kunzwisisa kuumbwa nyaya vaishandisa pasi kabhoni simbi machira, kutonhora anokungurutsirwa, GOST 19904-90. chicherwa microstructure Pashure pokukungurutsira zvikuru anosarudza plasticity kwayo, ceteris paribus.

Cold akakungurusa hwendarira anogadzirwa 0.25-5.0 mm gobvu uye rinowanika machira ane dzakasiyana makuriro - kubva 510h710 mm kusvika 1250h2500 mm. Steel 0.25-2 mm gobvu kwakakurudzira zvinogona kusvitsa. Cold-akakungurusa simbi jira transformer kubudisa 0,28-0,5 mm gobvu papepa kukura 750-1000 mm. By transformer simbi inokosha zvinoda kuisa mberi, zvinoti - kukosha rinobva nekubudisa arambe achirema uye watt kurasikirwa resolution. Uye kubereka Pepa chando anokungurutsirwa simbi rwakapetwa STRUCTURAL steels, mukuru chiwanikwa STRUCTURAL steels inokosha chinangwa zvemagetsi pasi kabhoni nesilicon steels. Yakabudiswa chando harikunguruswi ubvise muchirimo, chombo, nokuti rinobva matunhu.

Zvakakurukurwa kutonhora yakanyikwa jira

mukuru-chinangwa inotonhorera-akakungurutsa jira anobudiswa kubva steels vane makemikari anoumba rinorondedzera GOST 1050-88: 08ps, 08kp, 10PP, 10ps, 15 Pis, 15kp, 20ps, 20kp, 25, 30, 35, 40, 45. Kuti chando rinopfungaira iri pasi punching mhando simbi mamakisi 08U, 08kp uye 08ps. Cold akakungurusa simbi pamusoro unotedza uye kunyatsoenderana geometric zvitarisiko.

Kusiyana zita raro, kutonhora akakungurutsa simbi hakurevi kunzvenga kupisa kurapwa. Chero inotonhorera-anokungurutsirwa simbi rinobudiswa kubva inopisa anokungurutsirwa billet.

chando akakungurusa simbi kugadzirwa

Jira inotonhorera-yakanyikwa zvinoitwa nenzira mbiri: rimwe jira kana roll. Pepa-nzira yakabereka hot-harikunguruswi simbi pashure chando rinopfungaira unotemwa kupinda machira, zvavakazviitira wakaparadzaniswa akatuma zvimwe kubudiswa (annealing, kuswatura and unto.).

Mumazuva ano kugadzirwa muitiro kuti rwakapetwa aanoda. Panyaya iyi, vose kugadzira zvokukura X / K simbi mabhanzi uye ari kuitwa vakagadzirira akagadzirwa zvigadzirwa kubudikidza Chinyorwa kana otomatiki racherwa machira. Round nzira inoita zvoga hombe kubudiswa kushandiswa, anowedzera zvibereko rakapedzwa chigadzirwa, anovandudza ehupfumi ari simbi uye chimiro kugadzikana nokuda mukugadzira muitiro. With nzira iyi kuwedzera goho ose apera zvigadzirwa runobvira pamusoro chete munzvimbo. Mune zvimwe zviitiko inotonhora-anokungurutsirwa hwendarira yaipiwa mu mabhanzi. Zvichienderana kugadzira muitiro vamwe muchina-kuvaka emakambani, zvinobatsira kuderedza uwandu tsvina. In pagadzirwe chando anokungurutsirwa simbi rokumanikidzirwa akavhiyiwa vari kuchenesa descaled hot-anokungurutsirwa ubvise achifinyamisa zvigayo kuti (reversible kana kuramba), kupisa kurapwa, nokuveza, kuswatura.

Kusiyanisa zviri hot-yakanyikwa uye chando-akakungurusa

Hot simbi iri nyore ribude. Nokuti nyaya zvinoitwa inopisa rinopfungaira rinoshandiswa zvikuru yakaderera-giredhi, rezasi mari simbi. Finished zvigadzirwa kazhinji yakafukidzwa pamwero uye inoda okuwedzera kurapwa. Sezvo hazvibviri kuverenga simbi deformation miganhu panguva kutonhora inopisa anokungurutsirwa simbi geometry rwakasiyana nekuomarara (gogonera ukobvu, hadzina kufambiswa zvakanaka pamusoro kumicheto uye makona).

Cold-rinopfungaira nzira runoita kuti tirambe chaiyo yaidiwa miganhu zvigadzirwa. Pose yakadaro anokungurutsirwa mvere, dzakafanana ukobvu, saka yokupedzisira chigadzirwa kurapwa kuri kushoma, uye dzimwe nguva kunyange kuzvireva. Nokuda homogeneous mamiriro, kutonhora akakungurutsa simbi Kunogara uye ane unhu nani panguva yokumbozorora, vachikotama, achitambanudza. Kugadzira simbi yacho mamakisi.

Kushandisa chando-anokungurutsirwa simbi

Cold-akakungurusa simbi inoshandiswa sectors zhinji: mune motokari bodywork, michina kuti zvivako, maindasitiri midziyo, muchina zvikamu, kuvakwa, kubudiswa maindasitiri, kugadzirwa weimba midziyo yemagetsi.

3 akauraya simbi chando - rimwe mutengo kupfuura zvinodhura. Minimum okisijeni kugutsikana runogonesa kuti homogeneity mamiriro, plasticity uye ngura nemishonga. Rinoshandiswa kuti zvakaoma simbi zvivako uye akatakura mutoro-zvinhu, STRUCTURAL zvitarisiko, zvidimbu nyere Fittings. Cold-akakungurusa simbi inoshandiswa kugadzirwa yenhengo vachibatwa chafariz uye nemakemikari kurwisa.
