Aya mameseji haasi ekupa michina, mapepa ebvunzo kana sevhisi zvinyorwa zveSavo Kusić. Ikozvino kupihwa kwakanangana nemahwindo, magonhi uye anosanganisirwa mhinduro.
Chinangwa uye marudzi ematenderedzwa masaha
Michina yemasaha edenderedzwa inoshandiswa kucheka matanda akachinjika kuita mapuranga nematanda, kurebesa, kuchinjika kana diagonal kucheka kwemapuranga zvichienderana nehukuru hwakatarwa. Michina yedenderedzwa yesaha inoshandiswa kucheka matanda kwakachinjika kuita mapuranga nematanda, kureba, kuchinjika kana kucheka kwediagonal kwemapuranga zvichienderana nekukura kwakatarwa.
Maererano neizvi, denderedzwa saw machines inogona kukamurwa kuva mapoka makuru anotevera: circular saw machines yekucheka matanda; michina ine denderedzwa saw ye longitudinal kucheka kwemapuranga; michina ine denderedzwa saha yekucheka mapuranga makobvu kuita matete: michina ine denderedzwa saha yekucheka yakachinjika; michina ine denderedzwa saha yelongitudinal, transverse uye diagonal yekucheka (universal).
Zvinhu zvinochekwa zvinogona kudyiswa mumushini nemawoko kana nemuchina. Michina yekuisa mumushini inogona kunge ine rollers, ine rollers uye discs, uye inoteverwa. Kuteedzerwa kuisirwa ndiyo yakanyanya kukwana, sezvo ichiva nechokwadi chekucheka kwakaringana, chengetedzo uye nzira dzekuchengetedza dzekushanda pamichina (fig.1)

Michina ine denderedzwa masaha inogona kuva nesaha rimwe, maviri kana kudarika.
Iyo yehunyanzvi hunhu hwemhando dzakajairika dzemakina ane denderedzwa saw anopiwa patafura 1. Pakuyambuka kucheka kwemapuranga mumamiriro ekuvaka ekumaruwa, denderedzwa pendulum saw yemhando 4 - KM, iyo inoratidzwa mufig. 2. Zviri nyore kubata, kugadzira zvakanyanya uye inopa kunaka kwekucheka.

Nhoroondo kuverenga kwekubudirira
Kugadzirwa kwependulum saw kune imwe shanduko muzvidimbu zvezvinhu zvakagadzirwa zvinogona kutsanangurwa neformula P =480 Kg(n - m), apo P ndiyo nhamba ye steaks yeimwe shift; n - nhamba yekucheka paminiti; m - kucheka kwekuwedzera kwekuyera huma uye kucheka nzvimbo dzakakanganisika. Kana nhamba yekucheka yasvika7paminiti, m inotorwa kuve yakaenzana1-2, uye kana nhamba yekucheka inobva8-12paminiti, m inotorwa seyakaenzana2ku8; Kg - Coefficient yekushandiswa kwezuva rekushanda, iyo inofunga kukanganisa mukushanda kwemuchina, nguva yekuti vashandi vazorore, nguva yekugadzirisa muchina, nezvimwewo. Pamichina ine chikafu chemaoko, Kg inotorwa ingangoita.0,93.
Kugadzirwa kwemuchina une denderedzwa saw muzvidimbu zvezvinhu zvakagadzirwa mukuchinja kunogona kutariswa zvinoenderana neformula: P =480uye Kd Kst/ Lm, uko P - kugadzirwa muzvidimbu zvezvinhu zvakagadzirwa panguva imwe chete; i - displacement speed; Kd - iyo coefficient yekushandiswa kwezuva rimwe yakaenzana0,9; Kst - coefficient yekushandiswa kwemuchina, iyo yakaenzana ne0,6; L - kureba kwezvinhu, m; m - avhareji nhamba yekucheka kwechimwe chinhu.
Sheets uye mazino profiles
Mablades emasaha edenderedzwa akakamurwa kuita flat, double-cone, right-cone, left-cone uye planing saw maererano nekuvaka kwavo.
Circular flat saw blades anonyanya kushandiswa kureba uye transverse kucheka kwehuni. Zviyero zvavo zvinopihwa mutafura.2.
Tafura2: Dimensions of flat circular saw blades for longitudinal and transverse cut of wood
Madhayamita egomba resaha ndeaya: 20, 80, 40, 50, 75 uye 85 mm. Saw blades akagadzirwa ne 89 brand simbi. Maprofiles uye zviyero zvemeno emazino emashizha e-flat circular saw for longitudinal uye transverse yekucheka kwehuni inopiwa mufig. 4. Mutafura. 3 ndiwo saizi yemakona emablades emazino akati sandara emasaha akatenderedzwa. Kureba kwezino rezino uye radius yekutenderera kwekona yemukati inotarirwa kubva kune zvinotevera zviyero: Muchiitiko chekucheka, longitudinal cutting h = (0,4 / 0,5)t; Muchinjika-kucheka saw h = (0,6 / 0,9)t; Kumasaha ekucheka kwenguva refu uye kuchinjika h = (0,1 / 0,15)t.

Nhoroondo yekuchengetedza maitiro uye kugadzirisa
Mashizha edenderedzwa emasaha anorodzwa pamichina yekurodza otomatiki, uko isingashanduke chimiro kana saizi yekona yekucheka, kurodza, kana kona yemukati neyekunze. Kucheka kwemazino matsva kunoitwa nemichina yakakosha yekubaya nemusoro wakakodzera. Kudzora chimiro chemazino uye ukuru hwezvinhu zvekona kunoitwa neakakosha matemplate uye protractors.
Panzvimbo yekurodza mazino egutter, denderedzwa uye bhendi saws, yekucheka longitudinal, kudzvinyirira kwavo dzimwe nguva kunoitwa, kunosanganisira kuwedzera kumucheto kwemeno. Kubatsira kwekumanikidza pamusoro pekupisa kunosanganisira kuti saizi yekupisa haichinji panguva yekushanda, simba rekucheka rinoita symmetrically pazino, uye murwi weukobvu hwakaenzana unobviswa. Pamusoro pehupamhi hwese hwekucheka, pitch yezino inogona kuwedzerwa ne30-40%, pasina kuderedza kunaka kwekucheka.
Panguva yekucheka, kuputika kwehukuru hwakasiyana uye kutungamirirwa kunoonekwa mumucheka wesaha, izvo zvinotungamirira pakusikwa kwezviputi munzvimbo dzisina simba, nezvimwewo. Pamberi pechigadziko chesaha chakaiswa pamushini wemashini, inofanira kunge iri nyore nyundo, iyo inobvisa kushushikana kwakamuka mairi. Nechinangwa ichi, chirairo, tafura yekutarisa saha, sando, vatongi, mutongi wekutarisa kurongeka, nezvimwe.
Kuparadzira mazino kunoitwa nevashambadziri. Ukuru hwekupararira mumatambudziko akawanda hunotorwa 0,6 ku 0,75 mm kune rumwe rutivi, pasinei nehupamhi hwesaha, asi uchifunga nezvemhando uye hunyoro hwehuni. Kuwanda kwehunyoro hwehuni, ndiko kukura kwe swagger yesaha. Saizi yekupararira kwemazino esaha inodzorwa neakakosha matemplate.
Kuiswa kwesaha blade pamushini shaft kunofanirwa kuitwa uchisangana nemamiriro anotevera. Nzvimbo dzekusangana dzemahwendefa eparutivi rwesaha dzinofanirwa kunge dzakanyatsoenderana neiyo shaft inotenderera. Pakati pemasaha blade inofanira kupindirana nechepakati pe shaft. Kugadziriswa kwechidzitiro chesaha nenzira yemahwendefa emativi kunofanira kunge kwakachengeteka. Banga rinotsemura rinofanirwa kunge rakamira rakanangana nesaha. Iwo madhairekitori uye anopinza mune slot yetafura anofanirwa kugadziridzwa chaizvo zvinoenderana nesaha. Mukaha unobvumidzwa pakati pesaha neshaft haufanire kunge wakakura kupfuura 0,2 mm. Kana mamiriro aya akasazadzikiswa, kucheka kwemhando yakaderera kunowanikwa uye mune dzimwe nguva, kutadza kwemuchina kunoitika.
