Pane Nzira Yekunzvenga Burr Kana Uchishandisa Laser Kucheka Machina?
Mhinduro ndihongu. Mukuita kwepepa simbi yekucheka kugadzirwa, iyo parameter kumisikidza, gasi kuchena uye kudzvanywa kwemhepo kwefiber laser yekucheka muchina kuchakanganisa kunaka kwekugadzirisa. Inoda kugadzikwa zvine mutsindo maererano neyakagadziriswa zvinhu kuti iwane yakanakisa mhedzisiro.
MaBurrs anonyanya kusara zvimedu pamusoro pezvinhu zvesimbi. Apo iyosimbi laser yekucheka muchinainogadzira iyo workpiece, iyo laser danda inovhenekera pamusoro peiyo workpiece, uye iyo inogadzirwa simba inopfungaira pamusoro peiyo workpiece kuzadzisa chinangwa chekucheka. Paunenge uchicheka, gasi rinobatsira rinoshandiswa kukurumidza kuputika slag pamusoro pesimbi, kuitira kuti chikamu chekucheka chive chakanaka uye chisina burrs. Magasi anobatsira akasiyana anoshandiswa kucheka zvinhu zvakasiyana. Kana iyo gasi isina kuchena kana kuti kudzvinyirira hakuna kukwana kukonzera kuyerera kuduku, slag haingaputirwi yakachena uye burrs ichaumbwa.
Kana iyo workpiece ine burrs, inogona kutariswa kubva pane zvinotevera zvinhu:
1. Kana kuchena kwegasi rekucheka hakuna kukwana, kana kusina kukwana, shandura iyo yakakwirira yekucheka gasi rinobatsira.
2. Kunyangwe iyo laser yekutarisa chinzvimbo chakarurama, iwe unofanirwa kuita yekutarisisa chinzvimbo bvunzo, uye uigadzirise zvinoenderana neiyo offset yekutarisa.
2.1 Kana iyo yekutarisa nzvimbo yakanyanyisa kukwira, izvi zvinowedzera kupisa kunobatwa nechepazasi pekupedzisira workpiece kuti ichekwe. Kana iyo yekucheka kumhanya uye yekubatsira mhepo yekumanikidza inoramba iripo, zvinhu zviri kutemwa uye iyo yakanyungudutswa padhuze ne slit ichava yemvura pazasi. Izvo zvinhu zvinoyerera uye zvinonyungudutswa mushure mekutonhora zvinonamatira kune yakaderera pamusoro peiyo workpiece mune spherical shape.
2.2 Kana iyo chinzvimbo ichinonoka. Kupisa kunotorwa nechepasi pekupedzisira pamusoro pezvinhu zvakachekwa kunoderedzwa, kuitira kuti zvinhu zviri mumucheka hazvigone kunyungudutswa zvachose, uye mamwe masara akapinza uye mafupi anonamatira kune yakadzika pasi pebhodhi.
3. Kana simba rekubuda relaser rakakwana, tarisa kana laser iri kushanda zvakajairika. Kana zvakajairika, tarisa kana kukosha kwekubuda kwebhatani rekudzora laser kwakaringana uye gadzirisa zvinoenderana. Kana simba racho rakakura kana kuti duku, chikamu chakanaka chekucheka hachigoni kuwanikwa.
4. Iyo yekucheka kukurumidza kwe laser cutting machine inononoka kana kuti yakakurumidza kana kuti inononoka kukanganisa maitiro ekucheka.
4.1 Mhedzisiro yekukurumidza kukurumidza laser yekucheka feed kumhanya pakucheka mhando:
Inogona kukonzera kusakwanisa kucheka uye kupisa.
Dzimwe nzvimbo dzinogona kugurwa, asi dzimwe nzvimbo hadzigone kugurwa.
Inoita kuti chikamu chose chekucheka chive chakakora, asi hapana kunyunguduka kunogadzirwa.
Kucheka kwekudya kunokurumidza kukurumidza, zvichiita kuti pepa rive risingakwanisi kutemwa munguva, chikamu chekucheka chinoratidza nzira ye oblique streak, uye kunyunguduka kunogadzirwa muhafu yepasi.
4.2 Mhedzisiro yekunonoka yakanyanyisa laser yekucheka feed kumhanya pakucheka mhando:
Itai kuti pepa rakachekwa rive rakanyunguduka, uye chikamu chekucheka chakashata.
Mushonga wekucheka uchawedzera zvichienderana, zvichiita kuti nzvimbo yose inyunguduke pamakona maduku akakomberedzwa kana akapinza, uye iyo yakanakisa yekucheka maitiro haigone kuwanikwa. Kudzika kwekucheka kwekucheka kunokanganisa kugona kwekugadzira.
4.3 Ungasarudza sei kukurumidza kucheka kwakakodzera?
Kubva pakucheka mazhenje, kukurumidza kwechikafu chekudya kunogona kutongwa: Kazhinji, mazhenje ekucheka anopararira kubva kumusoro kusvika pasi. Kana maspark akarerekera, kukurumidza kwekudya kunokurumidza;
Kana maspark asina kupararira uye madiki, uye akapfupikiswa pamwe chete, zvinoreva kuti kukurumidza kwekudya kunononoka. Rongedza kumhanya kwekucheka zvakakodzera, nzvimbo yekucheka inoratidza mutsara wakadzikama, uye hapana kunyunguduka kunyungudika pahafu yepasi.
5. Air pressure
Mune iyo laser yekucheka maitiro, iyo yekubatsira mhepo yekumanikidza inogona kuvhuvhuta kubva kune slag panguva yekucheka uye kutonhorera iyo inopisa-yakakanganiswa nzvimbo yekucheka. Magasi ekuwedzera anosanganisira okisijeni, mweya wakamanikidzwa, nitrogen, uye magasi anert. Kune zvimwe simbi uye zvisiri zvesimbi, inert gasi kana mhepo yakamanikidzwa inowanzoshandiswa, iyo inogona kudzivirira zvinhu kubva pakupisa. Zvakadai sekucheka kwealuminium alloy zvinhu. Pamusoro pezvinhu zvakawanda zvesimbi, gasi rinoshanda (zvakadai seokisijeni) rinoshandiswa, nokuti okisijeni inogona kukonzera simbi pamusoro uye kunatsiridza kucheka kushanda.
Kana mhepo yekubatsira yemhepo yakanyanyisa, eddy currents anoonekwa pamusoro pezvinhu, izvo zvinoderedza kukwanisa kubvisa zvinhu zvakanyungudutswa, izvo zvinoita kuti chidimbu chive chakafara uye nzvimbo yekucheka ive yakaoma;
Kana kudzvinyirira kwemhepo kwakanyanyisa, zvinhu zvakanyungudutswa hazvigoni kuputirwa zvachose, uye pasi pepamusoro pezvinhu zvichanamatira kune slag. Naizvozvo, iyo yekubatsira gasi kumanikidza kunofanirwa kugadziridzwa panguva yekucheka kuti uwane yakanakisa yekucheka mhando.
6. Nguva yakareba yekushanda yemuchina wemuchina inokonzera kuti muchina usagadzikana, uye unoda kuvharwa uye kutangazve kubvumira muchina kuzorora.
Nekugadzirisa zvirongwa zviri pamusoro, ndinotenda kuti unogona kuwana nyore inogutsa laser yekucheka maitiro.
