Nthawi zina timafunika kudula nkhuni pakhomo kapena kudula munda . Choncho, banja liyenera kukhala ndi hacksaw pamtengo.
Koma ngakhale chophweka ichi, poyamba, chida chimakhala ndi kusiyana kwakukulu, zosiyana ndi wopanga ndi mtengo, komabe ndi makhalidwe ofunikira monga kutalika kwa nsalu, kukula kwa dzino, mtundu wa chogwirira ndi chitsulo.
Kodi mungasankhe bwanji hacksaw pa nkhuni?
Choyamba, choyamba muyenera kuonetsetsa ubwino wa chingwecho - kalasi yazitsulo, njira yovuta komanso khalidwe la kugaya. Kuchokera kuzimenezi zidzadalira kuti ntchitoyi ikhale yogwirizana, komanso moyo wake wautumiki.
Mlingo wolimba wa chitsulo kwa hacksaws pa nkhuni ndi 45 HRC ndi 55 HRC kwa mano. Mtundu uwu wa hacksaw umatanthawuza kusinthasintha ndi kusagwira. Zimakhala zosavuta kuzindikira ndi mdima wandiweyani wambiri poyerekezera ndi zina zonse. Komabe, hacksaws izi sizingatheke. Sinthani ndikuwongolera mazenera okha omwe mano opangidwa ndi zitsulo zowunjika.
Malingana ndi kutalika kwa nsalu, kusankha kwake kumadalira pa zosowa zanu. Ngati mukufuna kupanga zidutswa zing'onozing'ono ndi matabwa, masentimita 30 ndi okwanira. Koma pomanga ndi kukhala ndi dacha, ndibwino kuti mupeze nsalu ndi nsalu ya 45-50 cm ndi zina zambiri.
Kawirikawiri, malingana ndi kutalika kwa tsamba la macheka, mungagwiritse ntchito njira iyi yowerengera: kutalika kwa hacksaw kuyenera kukhala wofanana ndi kutalika kwa awiri a billet wamkulu omwe mudzakhala nawo. Kuchuluka kwa chiŵerengerochi kumapangitsa kuchotsa mwachangu utuchi pa nthawi yowonera chifukwa cha kuchoka kwathunthu kwa mano omwe akugwiritsidwa ntchito. Ndipo zidzakhala zophweka kwa manja pamene kusuntha kwakukulu sikudzakhalanso.
Chotsatira chotsatira macheka a macheka pamtengo ndi kukula kwa mano ndi kuwongolera. Izi zimapangitsa kuti liwiro likhale lachangu komanso lolondola. Zing'onozing'ono dzino, ndizomwe zimadulidwa kwambiri, koma pansi mofulumira, komanso mosiyana. Kuwombera pamtengo ndi dzino lalikulu kumathandiza kuchepa pang'ono, koma kudula kudzakhala kovuta.
Ngati mukufuna chosowa chodula mitengo, chitsanzo ndi dzino laling'ono ndilosafunika, chifukwa ukhondo wadulidwe suli wovuta kwambiri, koma kuchepetsa mwamsanga ndi kuyesayesa kotayidwa ndizofunikira kwambiri. Pankhaniyi, mtunda wa 4-8 mm ndi wokwanira.
Ngati mukusowa chowoneka chowongolera, gulani mwambo wamtundu ndi mano a katatu. Mitundu yamakono yomwe imakhala ndi mano opatsirana pambuyo poti kusinthasintha kumasintha kwathunthu kapena kungokhala mbali imodzi yazitsulo. Komabe, ndi izi iwo apatsidwa mphamvu zamphamvu komanso zothazikika.
Chofunika pakusankha malo osokoneza ndi khalidwe ngati ergonomics ya chogwirira. Izi zimatsimikizira chitonthozo chanu pa ntchito.
Kupaka nkhuni zosungira nkhuni
Mtundu uwu wa hacksaw ndi wamba pakati pa alendo ndi anthu okhala mumzinda wa maofesi, pamene palibe chofunikira cha macheka aakulu, kuphatikizapo ndizosokoneza kwambiri kusunga ndi kunyamula nawo.
Masamba oyendayenda ali ndi malo ochepa kwambiri, chifukwa ndi osavuta kusunga ndi kunyamula, pambali pake palibe chifukwa chophimba, chifukwa gawo loopsya ndi mano limabisala muchithunzicho.
Khungu laling'onoting'ono kakang'ono kamatha kudulidwa ndi thunthu la mtengo wolemera masentimita 14. Choncho ndi ntchito zosavuta zowononga nkhuni kapena kututa nkhuni, zimatha kusintha.
Komanso, machenjezo oterewa sungathekekeke pokonzanso zing'onozing'ono m'nyumba, mwachitsanzo, ngati mukufuna kukonza mapangidwe a matabwa musanafike khonde komanso nthawi zina.
Kufotokozera mwachidule
Choncho, posankha phokoso pa nkhuni, muyenera kudziwa zolinga ndi momwe zimagwiritsidwira ntchito mobwerezabwereza, zomwe zidzasankha kukula kwa tsamba ndi mtunda pakati pa mano.
Mulimonsemo, sankhani mankhwala abwino, otalika komanso osagwira ntchito, kuti kugula kumakhale kosangalatsa komanso kopindulitsa.
