Céard é bolt scagán?
Is fheistniúil aonair é bolt scagán a úsáidtear i mhiotalaíochtaí móra, go háirithe i n-inneallí arda agus bulldozers. Tá sé dírithe chun na scagáin den fhréamh cáin chun chéile a shocraithe.
Bolt & nut D475 segment
Méid: M30×120mm
Cainneacht: 1.24KG
Céim: 12.9
Bainriacht: 40Cr
Uimhir chuid bolt: 198-27-32231
Is féidir go mbeadh na méid stándaire don scraibh agus donn nutt do sheasmhach a athrú de bharr an ghníomh agus an mód de sheasmhach. Iontarfhocail coitianta iad M12, M16, M20, agus M24.
Céim-1: Seiceáil ábhar uimhlean agus stóráil
Ábhar uimhleán don scraibh a shonrú leis an díghnéathaíocht bunaithe ar úsáid. Níor chóir an t-ábhar atá le baint amach a sheiceáil agus ansin cónaí stórála ceart a aimsiú chun fonn deartháireacht a chaithfheidh a shainiú agus cúmhracht cheart a thabhairt dó.
Céim-2: Bunatrú scraibe gan cruthú
Úsáidtear i gcónaí casadh agus cruthú sa chéad seo. Is féidir méthóidí eile a úsáid freisin:
1. Sínitear
2. Protaitheach (Tairbheach)
Céim-3: Machanach CNC
Tar éis go ndéantar an phríomhpáirt trí ród casadh/cruthú, cruthaítear sí ar nós is gá sin nóímhneacha de ghnáth trí mhachanach CNC.
Na rudaí a dhéanann tar éis leathnú anseo: tuarascáil, in áit, agus glúin.
Céim-4: Nua-ábhar Teamhair
Déantar nua-ábhar teamhair tar éis an máthar a dhéanamh chun na fáscairí a chur níos láidre. Iarrachtar rudaí hardening & tempering.
Ar dtús, déantar hardening mar atá an bolt ag titim go téamh 850-900°C agus ansin glacadh isteach i meán cooing.
An dara chéim, glacaítear an bolt arís chun an bolt thar a bheith láidir a chur níos blanda, chun go mbeidh an bolt níos láidre. Déantar ath-titim chun an bróntas den bolt a bhaineadh amach a d'fhéadfadh tar éis hardening.
Céim-5: Fionnú Sraith
An chéad ní os cionn sin, tá an fionnú sraith a dhéanamh. Géarfaidh síos ar an gcéim seo gur chóir an tsraith a ghlanadh go soiléire leis na spécifcáidí fionnaithe.
Céim-6: Rólach Fhiadain
Tar éis an phróiseas fionnaithe, déantar rólach fiadain le dhá díon. Tá ceann acu staighre agus ceann eile atá ag bogadh, ag cur sprioc ar na boltóga agus ag cruthú na ndráideanna.
Céim-7: Cúmhrú
Tar éis an cruthú snáithe, glanann tarraingtí agus comhbróna scruibe le haghaidh fágáil rósc agus coróinse. Is maith an exempla de chlúdach tarraingtí clúdach geomet ar tharraingtí a chuirfear isteach i SST (Salt Spray Test) de bharr idirnód phríomhshamhla mar a riaghtar.
Úsáidfear mackám FISCHERSCOPE chun tickéad clúdaithe a mhéadú faoi láthair le cúrsaí eile méaduithe tickéad mar shampla amtráid tickéad clúdaithe.
Céim-8: Seiceáil don Fhiormhún, Léiriú & Feidhm:
Tar éis gach na n-airgead a dhéanamh, féadfadh an páirt seo dul i gcás seiceála. D'fheabhsfaidh sé
1.Tástál torcaigh, SST
2.Montáil le héit
3.Forc iompaithe (Tástáil Charpy iompaithe)
4.Tástáil neamhspréadachta (%foghlaim den bholt)
5.Ceannscartacht chrua den bholt
6.Fogartha coibhthe
