Carbide saw blade ndi zida zodulira zomwe zimagwiritsidwa ntchito kwambiri pokonza matabwa. Ubwino wa masamba a carbide umagwirizana kwambiri ndi zinthu zomwe zakonzedwa. Kusankhidwa koyenera komanso koyenera kwa macheka a carbide ndikofunikira kwambiri pakuwongolera zinthu, kufupikitsa nthawi yokonza, ndikuchepetsa mtengo wokonza.
1. Kusankha masamba a carbide saw
Carbide anawona masamba monga magawo angapo monga mtundu wa aloyi wodula mutu, zakuthupi masanjidwewo, awiri, chiwerengero cha mano, makulidwe, dzino mawonekedwe, ngodya, kabowo, etc. magawo kudziwa processing mphamvu ndi kudula ntchito macheka tsamba. . Posankha tsamba la macheka, muyenera kusankha tsamba loyenera la macheka malinga ndi mtundu, makulidwe, liwiro la macheka, njira yocheka, liwiro la kudyetsa, ndi m'lifupi mwa njira yocheka.
(1) Kusankha mitundu ya simenti ya carbide
Mitundu yomwe imagwiritsidwa ntchito kwambiri ya simenti ya carbide ndi tungsten-cobalt (code YG) ndi tungsten-titanium (code YT). Chifukwa tungsten-cobalt carbide imakhala ndi kukana bwino, imagwiritsidwa ntchito kwambiri pamakampani opanga matabwa. Mitundu yomwe imagwiritsidwa ntchito kwambiri pakukonza matabwa ndi YG8-YG15. Nambala pambuyo pa YG ikuwonetsa kuchuluka kwa cobalt. Pamene cobalt ikuchulukirachulukira, kulimba kwamphamvu komanso kupindika kwa aloyi kumawonjezeka, koma kuuma ndi kukana kuvala kumachepa. Ndikofunikira kutero Sankhani malinga ndi momwe zinthu zilili.
(2) Kusankha matrix
1. 65Mn spring steel has good elasticity and plasticity, economical material, good heat treatment hardenability, low heating temperature and easy deformation, so it can be used for saw blades with low cutting requirements.
2. Chitsulo cha chida cha kaboni chimakhala ndi mpweya wochuluka komanso kutentha kwapamwamba, koma kuuma kwake ndi kuvala kukana kumatsika kwambiri kukakhala ndi kutentha kwa 200 ° C-250 ° C. Ili ndi kupindika kwakukulu kochizira kutentha, kusalimba kolimba, ndipo imakonda kusweka pakatha nthawi yayitali. Pangani zida zachuma zodulira zida monga T8A, T10A, T12A, etc.
3. Poyerekeza ndi carbon chida zitsulo, aloyi chida zitsulo ali wabwino kukana kutentha, kuvala kukana ndi bwino processing ntchito. The kutentha zosagwira mapindikidwe kutentha ndi 300 ℃-400 ℃, amene ali oyenera kupanga apamwamba aloyi zozungulira macheka masamba.
4. Chitsulo chachitsulo chothamanga kwambiri chimakhala ndi kuuma kwabwino, kuuma kwamphamvu ndi kukhazikika, komanso kusinthika pang'ono kosagwira kutentha. Ndichitsulo cholimba kwambiri chokhala ndi thermoplasticity yokhazikika ndipo ndi yoyenera kupanga macheka owonda kwambiri komanso abwino.
