Kwakabva zita rechando chekucheka saw:

Metal inotonhora sawing ndiyo chidimbu chekucheka muitiro wesimbi denderedzwa masaha. Chirungu zita rakazara: Circular Cold Sawing .Mukati mekugadzirwa kwesimbi, kupisa kunogadzirwa apo blade yesaha yakaona mazino echeka workpiece inotamirwa kune sawdust kuburikidza nemazino esaha, uye workpiece yesaha uye blade inochengetwa inotonhorera, saka inonzi cold sawing.

Mhando dzemasaha anotonhora:

High speed steel saw blade (HSS) uye TCT isa alloy saw blade

Zvishandiso zve-high-speed steel saw blades zvinonyanya kusanganisira M2 neM35. Iyo general sawing kumhanya kwesaha blade iri pakati pe10-150 m / s, zvichienderana nezvinhu uye kutsanangurwa kweiyo sawing workpiece; iyo yakavharidzirwa yakakwirira-yekumhanya simbi yakaona blade, iyo yekucheka inogona kusvika Kusvika 250 m/min. Kudya kwemazino emushonga wesaha iri pakati pe 0.03-0.15 mm / zino, zvichienderana nesimba, torque uye kunaka kweiyo blade yesaha yemidziyo yekucheka.

Iyo dhayamita yekunze yesaha blade: 50-650 mm; kuoma kweshizha resaha iHRC 65; blade yesaha inogona kuvhuniwa, zvichienderana nekukura kweiyo sawing workpiece, kazhinji inogona kugadzika ka15-20. Upenyu hwemasaha emucheka wesaha ndeye 0.3-1 mativi emamita (nzvimbo yekuguma kwechiso chebasa rekucheka) uye kutsanangurwa kweiyo yakakura-yepamusoro-yekumhanya simbi saw blade; kazhinji, iyo yakakwirira-kumhanya simbi ine inopinza inoshandiswa (inowanikwawo pamusoro pe2000 mm); mazino acho anogadzirwa nesimbi yakakwirira-yepamusoro nekuisa, uye yakaona Iyo substrate yepepa ndiyo vanadium simbi kana manganese simbi.

Zvinhu zveTCT zino alloy ndeye tungsten simbi; iyo general sawing kumhanya kwesaha blade iri pakati pe60-380 m / s, zvichienderana nezvinhu uye kutsanangurwa kweiyo sawing workpiece; mazino ekudyisa mwero we tungsten steel saw blade iri pakati pe 0.04-0.08.

Saw blade tsanangudzo: 250-780 mm; kune marudzi maviri eTCT saw blades yekucheka simbi, imwe mazino maduku, jira resaha rakatetepa, kukurumidza kwekucheka kwakakwirira, hupenyu hwemasaha hurefu, anenge 15-50 square metres; iri sahwi yakaraswa Imwe mazino makuru, blade yesaha yakakora, uye kukurumidza kwesaha kwakaderera, iyo yakakodzera kucheka maworkpieces makuru; dhayamita yesaha blade inogona kusvika kupfuura 2000 mm. Hupenyu hwebasa resaha kazhinji hunenge 8 square metres, uye inogona kuvhuniwa ka5-10.

Musiyano pakati pekumhanyisa simbi inotonhora yekucheka saw uye manganese simbi inobhururuka saha:

Cold sawing yakasiyana ne friction sawing, kunyanya nenzira yekucheka:

Manganese simbi inobhururuka yesaha blade: Manganese simbi yesaha blade inotenderera nekumhanya kukuru uye inokwesha pane workpiece uye friction saw blade. Munguva yekucheka, kutonhora kweiyo friction saw uye workpiece yakakwirira kwazvo, uye kupisa kunokonzerwa nekubatana ne welded pombi kunokonzera kuti ibvise, iyo inenge yakatsva. . Kupisa kwepamusoro kunoonekwa pamusoro.

High-speed simbi inotonhora yekucheka saw: vimba ne-high-speed simbi saw blade kutenderera zvishoma nezvishoma kukuya pombi yakashongedzwa, saka inogona kunge isina burr uye isina ruzha.
