Nzira yekucheka simbi?

Danho rekutanga mukugadzira simbi kucheka, uko kunosanganisira kungocheka zvinhu zvisina kubikwa kana kuzvipatsanura kuita maumbirwo kuti vawane maburi. Nzira dzakajairwa dzekucheka simbi dzinosanganisira: kucheka mavhiri, kucheka kucheka, kucheka murazvo, kucheka plasma, laser kucheka, uye waterjet kucheka.
Kukuya vhiri rekucheka
Iyi nzira inoshandisa vhiri rekukuya rinotenderera nekumhanya kucheka simbi. Inoshandiswa zvakanyanya nzira yekucheka. Mavhiri ekucheka mavhiri akareruka, anochinjika, ari nyore, uye ari nyore kushandisa, zvichiita kuti agamuchirwe zvakanyanya munzvimbo dzakasiyana siyana, kunyanya panzvimbo dzekuvaka uye mumapurojekiti ekushongedza kwemukati. Iwo anonyanya kushandiswa kucheka madiki-diameter sikweya machubhu, akatenderera machubhu, uye asina kurongeka-akaumbwa machubhu.

Saw yekucheka
Saw cutting (Saw cutting) zvinoreva nzira yekukamura maworkpieces kana zvinhu nekucheka mitsetse yakamanikana uchishandisa saha (saw disc). Saw kuchekwa kunoitwa uchishandisa simbi bhendi saha muchina. Kucheka zvinhu ndechimwe chezvinhu zvinonyanya kukosha mukugadzirwa kwesimbi, saka saw michina midziyo yakajairwa muindasitiri yekugadzira. Munguva yekucheka, iyo yakakodzera saw blade inofanira kusarudzwa zvichienderana nekuoma kwezvinhu, uye iyo yakakwana yekucheka kumhanya inofanira kugadziridzwa.

Kucheka Moto (Oxy-fuel Cutting)
Kucheka kwemurazvo kunosanganisira kudziyisa simbi kuburikidza nemakemikari anoita pakati peokisijeni nesimbi yakanyungudutswa, kuinyorovesa, uye pakupedzisira kuinyungudutsa. Iko kupisa gasi rinowanzoita acetylene kana gasi rechisikigo.
Murazvo wekucheka unokodzera chete mahwendefa e-carbon steel uye haushandi kune mamwe marudzi esimbi, akadai sesimbi isina tsvina kana mhangura / aluminium alloys. Zvakanakira zvaro zvinosanganisira mutengo wakaderera uye kugona kucheka zvinhu kusvika pamamita maviri gobvu. Izvo zvisingabatsiri zvinosanganisira nzvimbo yakakura yekupisa-inopisa uye deformation inopisa, ine rough cross-sections uye inowanzosara slag.

Plasma Kucheka
Kucheka kweplasma kunoshandisa kupisa kwepamusoro-tembiricha yeplasma arc kunyungudika munharaunda (uye kunyungudutsa) simbi iri pamucheto wekucheka kwechishandiso, uye inobvisa simbi yakanyungudutswa uchishandisa simba repamusoro-speed plasma kugadzira kucheka. Inowanzo shandiswa kucheka zvinhu nehupamhi hunosvika 100 mm. Kusiyana nekucheka murazvo, kucheka kweplasma kunokurumidza, kunyanya kana uchicheka mapepa akatetepa eakajairwa kabhoni simbi, uye nzvimbo yakachekwa yakatsetseka.

  

Laser kucheka

Laser yekucheka inoshandisa high-energy laser danda kupisa, kunyunguduka munharaunda, uye kunyungudutsa simbi kuti iwane kucheka zvinhu, zvinowanzo shandiswa kucheka kwakanaka uye kwakanyatso kucheka kwemarata esimbi matete (<30 mm).Laser yekucheka mhando yakanakisa, ine ese ari maviri akakwira kucheka kumhanya uye dimensional kurongeka.

 

Waterjet Kucheka
Waterjet yekucheka inzira yekugadzira inoshandisa yakakwira-kudzvanya majeti emvura kutema simbi, inokwanisa kuita imwe-nguva yekucheka chero chinhu pamwe chete nema curves. Sezvo svikiro iri mvura, mukana mukuru wekucheka kwemvura ndewekuti kupisa kunogadzirwa panguva yekucheka kunokurumidza kutakurwa nejet yemvura inomhanya-mhanya, kubvisa mhedzisiro yekupisa.
