Mashizha esimbi asina simbi anoshandiswa zvakanyanya mumaindasitiri mazhinji nekuda kwekugara kwawo, corrosion resistance uye kupera kwepamusoro. Nekudaro, nekuda kwehukobvu hwawo hwakasiyana, simbi isina simbi mashizha anofanirwa kupfuura nematanho akawanda mukuvaka, uye maitiro aya anogona kusiyana kubva kupurojekiti kuenda kune purojekiti.

Kucheka mashizha esimbi asina tsvina kunoda kusarudza nzira yakarurama yekucheka zvichienderana nehupamhi hwemashizha, kunyatsoita zvinodiwa uye zvishandiso zviripo. Heino gwara rakarongeka:

1. Zvinhu zvekufunga nezvazvo pakucheka simbi isina tsvina

Simbi isina tsvina inonetsa kutema nekuda kwehunhu hwayo, iyo inokanganisa kucheka mashandiro. Nyaya dzakaita sekudzikiswa kuomarara kwechinhu, kuramba kwayo kupisa uye maturusi anoshandiswa kucheka zvinouya pamberi:

Material properties

Simbi isina tsvina yakaoma uye inodzivirira kemikari, ichiita kuti ive yakakodzera kune akawanda maapplication, asi yakaoma kugadzira. Kupisa kwakanyanya panguva yekucheka kunogona kuita kuti iparare, nepo kuoma kwayo kuchikonzera kupera nekukurumidza kwechishandiso.

Sheet ukobvu

Mamiriro ebasa anoenderana nekukora kwezvinhu, mashizha matete anogona kutemwa nemaoko kana nemichina midiki, nepo mashizha akakora achida michina mikuru sekucheka plasma kana kucheka jeti yemvura. Kutarisira kupisa kwakakosha.

Kucheka chishandiso kusimba

Nekuda kwehunhu hwesimbi isina tsvina, maturusi akakosha senge carbide kana maindasitiri laser maturusi anodiwa pakucheka. Izvo zvakakosha kuti aya maturusi akakosha anogona kucheka zvakasununguka pasina kukonzeresa chero kukuvadzwa kwesimbi isina tsvina panguva yekucheka.

Thermal management

Sezvo izvi zvakaoma, maturusi akakodzera senge carbide maturusi uye maindasitiri lasers anodiwa. Ivo vanoshandisa yakakosha yekucheka michina kuti vawane mhedzisiro iri nani vachidzivirira kukuvadzwa kwemidziyo panguva yekucheka.

Kururama zvinodiwa

Zvichienderana nezvinodiwa zveprojekiti, iyo yakanyanya kurongeka inotsanangura maturusi ekucheka uye matekiniki. Laser kana mvura jet cutters inogona kuita macheki akanaka, nepo kune kucheka kuri nyore, maturusi akareruka semashears kana chigero anoshandiswa kucheka mapepa matete.

2. Kusarudzwa kwechishandiso uye ukobvu hunoshanda

Mashizha matete (≤1.2mm, senge pazasi 18 geji)

Zvishandiso zvemaoko

Aviation shears (matin shears): inokodzera kucheka kwakatwasuka kana kwakakombama, kuchinjika asi kushanda nesimba, inoda kucheka muzvikamu zvidiki kuderedza deformation; akakodzera mapurojekiti madiki.

Magetsi emagetsi (Nibbler): kuchekwa nekurova zvimedu zvidiki zvezvinhu, zvinokodzera maumbirwo akaomarara, dzikisa pepa warping uye deformation.

Laser kucheka: yakakwira chaiyo, isina burr-isina, yakakodzera kune zvinodiwa zvemaindasitiri, asi inoda tsigiro yemidziyo yehunyanzvi.

Maitiro akanaka

›› Deredza kupisa
Kazhinji, simbi yakaonda isina tsvina inobatwa nekupisa, zvichikonzera warping kana discoloration. Kana iwe ukashandisa chaiyo chishandiso kumhanya uye, kana zvichidikanwa, zvinotonhorera sekucheka mvura uye jets remvura, unogona kukwanisa kudzivirira izvi.

››Gadzirisa bepa
Ita shuwa kuti yakanyatso kugadzika kumusoro kuti ichekwe uye uone kuti haifambi ichiri kushanda. Izvi zvinodzivirira kupinda munzvimbo dzisina kufanira uye zvichikonzera mamwe mavanga papepa; zvichiita kuti zvive nani, zvakachena, uye zvakatemwa zvakanyanya.

›› Debur kumucheto
Kupinza (Sharpness) zvinoreva mukana wekupinza kana kukasharara pazviyo nepazasi penzvimbo mushure mekucheka. Zvinokurudzirwa kushandisa mudziyo wekubvisa kana sandpaper kuitira kuti iwe ugone kucheka zvakachengeteka uye uwane chitarisiko chaunoda.

Mahwendefa epakati uye akakora (1.2-3mm, akadai seasingasviki 1/8 inch)

Zvishandiso zvemagetsi

Jig saw (ine bimetallic saw blade): Shandisa 18-24 TPI yakanatswa-mazino blade, cheka nekumhanya kwakaderera uye shandisa inotonhorera kutonhora pasi kudzivirira kupisa nekuomesa.

Circular saw (carbide blade): Inoda kushandisa inotungamira mutongi kuve nechokwadi chekucheka kwakatwasuka, kupfapfaidza kucheka mafuta kuderedza kukwesha.

Plasma kucheka: Inokodzera kukurumidza kucheka mahwendefa akakora, asi inoda mhepo compressor uye yekudzivirira michina, uye kucheka kungangoda kukwenenzverwa.

Kutonhodza tekinoroji: Kupisa hakumbove dambudziko resimbi isina tsvina, asi kutonhora kwemaitiro panguva yekucheka kunogona kukonzera deformation kana kuneta. Zvishandiso zvakaita semvura, mhepo uye mvura yekucheka zvinogona kuderedza kupfeka pazvinhu, nekudaro zvichivandudza kusimba kweblade.

Mahwendefa akakora (≥3mm, senge 1/4 inch uye pamusoro)

Angle grinder (yakakosha vhiri rekukuya resimbi isina tsvina): yepakati kumhanya yekucheka, dzivirira kupisa kwakanyanya kukonzeresa kuoma kwezvinhu, uye pfeka zvekudzivirira.

Plasma cutter: yakakodzera nharaunda yeindasitiri, inoda mhepo compressor uye yekudzivirira yemidziyo, inobudirira kucheka mahwendefa akakora.

Laser / mvura jet yekucheka: hapana nzvimbo yakakanganiswa nekupisa, yakanyanya kurongeka, yakakodzera kune yakakwirira-chaiyo kugadzirwa kweakaomesesa maumbirwo, asi mutengo wakakwira.

Kucheka fluid uye lubrication: Hydraulic shears yakanyatsokodzera kucheka mutsara-mutsetse wetete-gauge simbi isina tsvina, kunyanya kune makobvu mahwendefa. Hydraulic shears inokwanisa kuisa dzvinyiriro huru kuti uwane akachena uye matete akachekwa munguva pfupi, saka akanakira maapplication anoda basa rakawanda.

Mazano: Kucheka mahwendefa esimbi asina tsvina, kucheka kweplasma, majeti emvura masisitimu, uye malaser emaindasitiri anofanirwa kushandiswa kuchengetedza kunaka kwezvinhu. Zvinonyatsozivikanwa kuti air conditioning uye kugadzirisa nguva dzose kunogona kuvandudza kushanda uye kusimba.

3. Unyanzvi hwekushanda hunokosha

Kudzora tembiricha

Simbi isina kusimba ine husina kunaka hwekupisa uye inoomesa nyore nyore kana kuremara nekuda kwekupisa kwakanyanya. Shandisa chinotonhodza (semafuta ekucheka) kana nzira yekuwedzera yekudyisa kuderedza tembiricha yekucheka uye kuwedzera hupenyu hwematurusi.

Dzivisa kuenderera mberi kwekucheka-kumhanya uye kumbomira kupisa kupisa panguva dzakakodzera kudzivirira kupisa kwenzvimbo.

Chishandiso uye parameter optimization

Tool zvinhu: Carbide kana cobalt-ine high-speed simbi maturusi anosarudzwa kuti zviri nani kupfeka kuramba.

Kucheka parameters: Yakaderera kumhanya uye yakakwira torque (senge pakudhirowa), ine mafuta ekuvandudza pamusoro pekupedzisira.

Feed mode: Kuwedzera kwekudya (kusiri kuenderera kucheka) kunogona kuderedza kupisa kuunganidza uye kuderedza tembiricha neinopfuura 30% zvichienzaniswa neradial feed.

Kurapa kwakatevera

Deburring: Polish iyo yakachekwa nefaira, sandpaper kana angle grinder kuti uve nechokwadi chekuchengetedza uye runako.

Pickling kuchenesa: Kana iwe uchida kubvisa oxide scale, shandisa yakasanganiswa asidhi (yakadai seHNO₃ + HF) pakunhonga, asi nguva yacho inofanira kudzorwa kuti usanyanya kuora.

4. Hunhu hwezvinhu uye nzira dzekugadzirisa

Austenitic simbi isina tsvina (yakadai se304/316): yakasimba ductility, nyore kunamatira banga, inoda yakakwirira kuomarara chishandiso uye kutonhora kwakakwana.

Molybdenum-ine simbi isina tsvina (yakadai se316): yakakwira corrosion kuramba, asi yakakwira yekucheka kuramba, zvinokurudzirwa kushandisa yakaderera kumhanya ine yakakwira lubricity inotonhorera.

Nyore-ku-kucheka mhando (yakadai se303): ine sulfur kana selenium zvinhu, izvo zvinogona kuwedzera kukurumidza kucheka, kuderedza kupfeka kwezvishandiso, uye yakakodzera kumhanyisa-kumhanya.

5. Kuchengetedza uye kuchengetedza

Kudzivirirwa pachako: magirovhosi, magirovhosi asingadzivirirwe, masikisi eguruva (kudzivisa inhalation yeguruva resimbi).

Equipment kuongorora: gara uchitsiva mashizha akasakara / mavhiri ekukuya kuti uve nechokwadi chekucheka zvakanaka uye kuchengeteka.

Kutarisira kwezvakatipoteredza: chengetedza kufefetedza kwemhepo, gara kure nezvinhu zvinobvira moto, uye chenesa tsvina dzesimbi nenguva.

Summary: Kucheka mahwendefa esimbi isina tsvina kunoda kutarisisa kwakadzama kweukobvu, zvinhu uye maturusi mamiriro, nekutanga kupihwa kudzora tembiricha uye kupfeka kwezvishandiso. Nekuda kwepamusoro-chaiyo zvinodiwa, zvinokurudzirwa kuburitsa laser / mvura jet kucheka; mukushanda kwemazuva ese, maturusi ecarbide + inotonhorera + yekuwedzera feed ndiyo inonyanya kushanda mhinduro. Iva nechokwadi chekuziva nzira dzakatetepa, dzepakati nepakati uye dzakakora, uye teerera kune dzakachena, dzakachengeteka uye dzakanyatso cheka zvidimbu kuti uone kuti kucheka kwese hakuna kukanganisa.
