Kukarukureta Formula

Iyo yekuverenga fomura yekusarudzwa kwemuchina wekufa-uchikanda: Kufa-kukanda muchina kusungira simba (t) = 1.4 * kukanda nzvimbo inofungidzirwa * chiyero chenzvimbo inofungidzirwa yeiyo kufa kukanda-iyo zvinyorwa zvinyorwa zvinofungidzirwa nzvimbo yeakafa kukanda. * modulus (CM2).

Iko tonnage yemuchina wekufa-unokanda unoratidzwa necamping simba remuchina.

Sezvo iyo yekufa-yekukanda chiwanikwa inorohwa mu "yakakwira-kumhanya uye yakakwira-kumanikidza" nyika, kana iyo yekufa-yekukanda muchina isina kunyatso kuvharwa, zvakakomba zvinhu zvinobhururuka zvichaitika, zvichikonzera zvakavanzika njodzi dzekukuvara kwebasa, yakashata saiti uye yakashata mhando ye castings.

Iyo yekuverenga fomula yekusarudzwa kwemuchina wekufa-wekukanda zvikamu zvekufa-zvinokanda zvinotevera:

Die-ichikanda muchina kusungira simba (t) = 1.4 * kukanda nzvimbo inoratidzwa * kumanikidzwa chaiko
Kukanda zvinofungidzirwa nharaunda-orthographic inofungidzirwa nzvimbo yekufa kukanda * modulus (CM2)

Kana iwe ukasarudza iyo yekufa-yekukanda muchina zvakasiyana maererano nehuremu kana saizi

Unogona kuita izvi:

Kukura: Kazhinji nzvimbo yekukanda yechigadzirwa (kusanganisira inodurura system), iyo unit inoverengerwa mu cm, yakakamurwa ne2.5, uye nhamba yakawanikwa ndiyo shoma toni inodiwa.
Kurema: Izvo zvinodikanwa kuti uzive huwandu hwekudurura huwandu hwemuchina. Mazhinji maparameter emuchina akasiyana neicho chaicho gadziriso yemuchina wepombi yezvinhu uye muchina wesobho. Semuenzaniso, dzidziso yekudurura vhoriyamu yematani 1250 ndeye 13-25.4kg. Muchokwadi, vazhinji vanofa-vachikanda michina chete vane yakanyanya kudururwa vhoriyamu ye10kg; fekitori paramende yematani gumi nematanhatu iri 12-1600kg kudira vhoriyamu, iri chaizvo ingangoita 17-32kg (zvinoenderana neyese fekitori yekumisikidza).

The tonnage of vanofa-vachikanda muchina ndiye clamping simba of vanofa-vachikanda muchina, kwete clamping simba. Iko kukakamira simba remuchina wekufa-kukanda kunoonekwa neiye ekumanikidza simba eiyo clamping humburumbira uye yekushandura simba yekuwedzera mashandiro, kwete simba reiyo clamping humburumbira. Kana iri toni yemuchina wekufa-uchikanda, zvine hukama nenzvimbo inofungidzirwa yenzvimbo yekufa-yekukanda (inosanganisira nzvimbo inofungidzirwa yeiyo yekufa-chikamu, slag bhegi, muchinjikwa mumhanyi, sprue nekeke ), zvakanakira kuverenga iyo chaiyo inofungidzirwa nzvimbo pane kushandisa coefficient. Nekuti iyo coefficient yechigadzirwa chezvikamu zvakakura haigone kuve yakanyanya kukwirira, uye coefficient yechigadzirwa yezvikamu zvidiki yakakwira, zvinonyanya kujeka kuverenga iyo yekumanikidza simba zvichienderana nenzvimbo chaiyo inofungidzirwa yeiyo mold. Kana iri sarudzo yekukanda kumanikidza, zvinoenderana nekunetseka kwekukanda, kazhinji kubva pa500bar kusvika 800bar.

Naizvozvo, iyo yekufa-ichikanda muchina inogona kupa 160t chakuvhuvhu simba, uye iyo yekufa-yekukanda muchina inonzi 160t.

Chaiyo Kushanda Kwekuverenga Pressure Inofa Inokanda Tonnage

Chigadzirwa changu xx magiramu uye saizi yacho xx * xx mm. Saizii yemuchina yandinofanira kushandisa kuipurinda? "- - Iri idambudziko rakajairika mukusarudza michina yekufa-yekukanda.

Kusarudzwa kwekufa kwekukanda muchina kunosanganisira zvinhu zvitatu:

1. Iyo toni yemuchina wekufa-wekukanda inoenderana nekuti zvinhu zvacho zvinobhururuka
2.Mold saizi, inoenderana kana iyo chakuvhuvhu inogona kuiswa pane yekufa ichikanda muchina

Kudurura huwandu, iyo inoenderana nekuti icho chigadzirwa chinogona kuumbwa

Maitiro ekuverenga chigadzirwa chemuchina tonnage?

Nezve dambudziko rekuverenga matoni emuchina wekufa, zvakaoma kutaura kuti hazvina kuoma, asi hazvisi nyore kutaura kuti zviri nyore. Chero bedzi iwe uchinzwisisa hukama, zviri nyore kuverenga muchina tonnage inodiwa yechigadzirwa.

Kutanga sarudza pfungwa yakadaro

The tonnage of vanofa-vachikanda muchina rinoreva clamping simba ari kufa-Kudzingwa muchina

Clamping simba ndiyo yekutanga paramende inoonekwa kana uchisarudza die yekukanda muchina. Basa re clamping simba ndere kunyanya kukunda bulging simba mune mhango, kukiya chakuvhuvhu, kudzivirira iyo yakanyungudutswa simbi kubva ichipaza, uye kuve neyakaenzana kurongeka kwekukanda.

Saka dzokera kumubvunzo wepakutanga, maitiro ekuverenga simba rekupwanya remuchina wekufa uchikanda muchina? Kutanga tarisa fomu inotevera:

Die-Kudzinga muchina clamping simba> chakuvhuvhu kuvhura simba F1 × 1.1

Saka, chii chiumbwa chekuvhura simba uye maitiro ekuchiverenga?

Mould kuvhura simba zvinoreva simba rinoshanda padumbu kuti chakuvhuvhu chiwedzere panguva yekufa ichikanda kugadzirwa. Iyo yekuvhura yekuvhura simba inogona kuwanikwa neinotevera fomula:

Kukanda nzvimbo × kukanda kumanikidza

Kudzinga nzvimbo

Kukanda nzvimbo A1 = a1 + a2 + a3 + a4 = keke nzvimbo + yemhanyi nharaunda + chigadzirwa nzvimbo + slag bhegi nharaunda

Nzvimbo yekufungidzira Kana iyo mold isina kunyatsogadzirwa, isu tinongoziva chete nzvimbo inofungidzirwa a3 yechigadzirwa, uye tinoifungidzira

a2 = 0.21a3
a4 = 0.12a3

Iyo nharaunda yekeke inoenderana nepunch

Mold kuvhura simba F1 = kukanda kumanikidza Pp × kukanda nzvimbo A1 + neutron chikamu simba Fc (kukarukureta chakuvhuvhu inovhura simba pamwe inotsvedza)

Kana paine inotsvedza neutron, neutron mamorekuru anoda kuverengerwa

Neutron chikamu Fc

Nyuturoni kudzoka simba Fr = chigadzirwa nzvimbo Ac × yakaverengwa kukanda kumanikidza × 75%

Neutron chikamu chinomanikidza Fc = simba rekudzosera neutron Fr × tanθ

Mold opening force F1=(a1+a2)×Pp+a3×Pp×0.75+a4×Pp×0.25+Fc

Kukanda kumanikidza kugovera:

Nekuti tembiricha yeforoma haina kukodzera uye kumanikidza kutapurirana hakuna yunifomu, kumanikidza kunoiswa pachikamu chimwe nechimwe kunosarudzwa uye kuverengerwa seinotevera:

Chigadzirwa department = rakaverengwa kurasa kumanikidza × 75%
Slag bhegi chikamu = yakaverengwa kukanda kumanikidza × 25%
Keke, mumhanyi chikamu = akaverenga kukanda kumanikidza × 100%

Kukanda kumanikidza kufungidzira:

Aluminium: Iyo inodzvinyirirwa nemhepo inowanzo kuve pamusoro pe80MPa, imwe 60MPa

Zinc: inenge 30MPa

Simba rekunamatira rinoda kuita ka1.1, XNUMX kana kupfuura simba rekuvhura chakuvhuvhu. Kana iyo yekuvhura yekuvhura simba iri yakakura kupfuura yekunamatira simba, kupenya (pfupi kupfura) uye kuwedzeredza zvingangoitika, uye chaiko kugadzirwa hakugone kuitiswa.

Mukupfupisa, yekupedzisira kuverenga kuverenga fomula yekufa muchina toni toni inogona kuwanikwa:

Clamping simba> mold kuvhura simba × 1.1 = kukanda nzvimbo × kukanda kumanikidza = (keke nzvimbo + mumhanyi nharaunda + chigadzirwa nzvimbo + slag bhegi nharaunda) × kukanda kumanikidza × 1.1

Kufa uchikanda muchina tonnage = clamping simba / 10, clamping simba unit ndiKN
