Mitundu ndi ntchito za macheka a band

Macheka a band amagawidwa m’mitundu yolemera yoyima komanso yopingasa podula matabwa kukhala matabwa ndi matabwa, macheka amtundu wapakatikati odulira matabwa ndi matabwa okhuthala kukhala macheka owonda komanso opepuka odulira matabwa owongoka ndi opindika ndi zinthu zina.

Mothandizidwa ndi macheka amagulu amtundu wolemera ndi wapakati, mosiyana ndi ma gutters, matabwa ndi matabwa amatha kudulidwa m’magulu, poganizira zolakwika ndi makhalidwe ena a zipika. Kuphatikiza apo, podula, amapereka m’lifupi mwake pang’ono, kotero kuti matabwa ochepa amapita mu utuchi.

Mu ntchito yothandiza ya makampani opanga zomangamanga pokonza nkhuni, makina okhala ndi macheka amtundu wa LC- amagwiritsidwa ntchito kwambiri.70ndi LC-80.

Band adawona LC-80

Technical chojambula cha ofukula band saw LC-80zokhala ndi miyeso yoyambira

Chithunzi 1 — Gulu loona LC-80.

Makinawa amakhala ndi thupi, tebulo lozungulira, mawilo awiri owonera - kalozera wapansi ndi cholumikizira chapamwamba, chipangizo cha brake ndi mota yamagetsi.

Makhalidwe aukadaulo LC-80

  • Diameter ya mawilo omwe gulu linawona likupita: 800 mm
  • Kudula m’lifupi - kudutsa: 715 mm
  • Kudula kwambiri: 570 mm
  • Band saw blade m’lifupi: mpaka 60 mm
  • Band saw blade kutalika: 3600–6000 mm
  • Table dimension:945×970 mm
  • Diameter ya gudumu lopatsira:285 mm
  • Chiwerengero cha magudumu amphindi pamphindi:620-800 mm
  • Mphamvu yamagetsi yamagetsi:3,2kW
  • Kulemera kwa makina:920 kg

Pa makina awa, matabwa wandiweyani amatha kudulidwa kukhala owonda pogwiritsa ntchito makina owonjezera. Makinawa amadula nkhuni ndi tsamba la macheka.

Masamba a Band

Technical zojambula za mbiri ya mano za ukalipentala ndi band saw blades

Chithunzi2- Mbiri ya band saw masamba.

Macheka omangira amawagawa mogwirizana ndi cholinga kukhala kalipentala, amene masamba ake ndi monga chida chodulira cha macheka a gulu la akalipentala, ndi ma scrapers, omwe mpeni wawo umagwira ntchito ngati chida chodulira macheka olemera ndi apakati. Macheka obwereza ali ndi mbiri I ndi II.

Miyeso ya mano a gulu la ukalipentala ma saw masamba amatha kutsimikiziridwa kuchokera ku chiŵerengero: phula la dzinot = (1,5 + 2,0) B, kutalika kwa dzinoh = (0,5 + 0,6) t, chili kutiBm’lifupi tsamba mu millimeters.

Utali wa masamba ndi utali wopindika

Pali kudalira pakati pa m’lifupi mwa tsamba la bandaw ndi utali wopindika wa chinthu chomwe chikudulidwa. Zimachokera ku mfundo yakuti ntchito yabwino ya macheka ndi yotheka ndi chikhalidwe chakuti m’lifupi mwake gulu la saw tsamba limayikidwa momasuka mu odulidwa. Izi zikapanda kukwaniritsidwa, zinthuzo zidzakhala zolakwika.

Zinthu za curvilinear zitha kudulidwa ndi masamba akulu ngati kukula kwake kuli kokulirapo kuwirikiza kuwirikiza kwa tsambalo. Choncho, tsamba la macheka limafalikira kotero kuti dzino limodzi lidumphidwe nthawi imodzi.

Kuwonetsa ndikukukuta mano

Band macheka masamba akhoza kufalitsa pa makina apadera basi, ntchito spreader manja kapena nyundo kuwomba mwachindunji pa dzino. Kuphatikiza pa kufalikira, kupanikizika kwa mano kumagwiritsidwanso ntchito pamakina apadera kapena kugwiritsa ntchito zipangizo zapadera.

Kukula kwa kufalikira kumayambira0,25ku0,30 mmzocheka matabwa ndi kuchokera0,40ku0,50 mmkwa scrapers pamene kudula conifers ndi chinyezi mpaka25%. Podula mitengo yolimba yokhala ndi chinyezi chochepa25%, zodzionetsera za mbali imodzi0,20-0,25 mmza ukalipentala ndi0,40-0,45 mmza jigsaws. Kwa mitundu yonse iwiri ya conifers ndi masamba otambalala, kufalikira kumawonjezeka ndikuwonjezera chinyezi chazinthu zomwe zimadulidwa.

Mitu yofananira: makina opangira matabwa ndi zida, makina ozungulira, macheka mitengo ya coniferous ndi hardwood mitengo, kumanga ndi kupanga mawindo ndi zitseko zamatabwa.
