Li-blades tsa Carbide li atisa ho sebelisoa lisebelisoa tsa ho itšeha bakeng sa ho lokisa sehlahisoa sa lehong. Boleng ba li-blades tsa carbide bo amana haufi-ufi le boleng ba lihlahisoa tse entsoeng. Khetho e nepahetseng le e utloahalang ea li-blades tsa carbide e bohlokoa haholo ho ntlafatsa boleng ba sehlahisoa, ho khutsufatsa nako ea ho sebetsa, le ho fokotsa litšenyehelo tsa ho sebetsa.
1. Khetho ea li-blades tsa carbide
Li-blades tsa Carbide li kenyelletsa li-parameter tse ngata tse kang mofuta oa hlooho ea alloy cutter, thepa ea matrix, bophara, palo ea meno, botenya, sebōpeho sa leino, angle, aperture, joalo-joalo. . Ha u khetha lehare la sakha, u tlameha ho khetha lehare le nepahetseng la sakha ho latela mofuta, botenya, lebelo la ho sakha, tsela ea ho sakha, lebelo la ho fepa, le bophara ba tsela ea ho seha ea thepa e sehiloeng.
(1) Khetho ea mefuta ea carbide e entsoeng ka samente
Mefuta e sebelisoang hangata ea carbide e entsoeng ka samente ke tungsten-cobalt (code YG) le tungsten-titanium (code YT). Hobane tungsten-cobalt carbide e na le matla a ho hanyetsa, e sebelisoa haholo indastering ea ho lokisa lehong. Mehlala e sebelisoang hangata ha ho etsoa lehong ke YG8-YG15. Nomoro ka mor'a YG e bontša peresente ea cobalt content. Ha litaba tsa cobalt li ntse li eketseha, matla a ts'usumetso le matla a ho kobeha a alloy a eketseha, empa ho thatafala le ho hanyetsa hoa ho fokotseha. Hoa hlokahala ho Khetha ho ea ka boemo ba sebele.
(2) Khetho ea 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. Tšebeliso ea tšepe ea carbon e na le k'habone e phahameng le conductivity e phahameng ea mocheso, empa ho thatafala ha eona le ho roala ho hanyetsa ho theoha haholo ha ho pepesehile mocheso oa 200 ° C-250 ° C. E na le deformation e kholo ea kalafo ea mocheso, ha e thatafallehe hantle, 'me e tloaetse ho phatloha ka mor'a nako e telele ea ho halefa. Etsa lisebelisoa tsa moruo bakeng sa lisebelisoa tsa ho itšeha tse kang T8A, T10A, T12A, joalo-joalo.
3. Ha ho bapisoa le tšepe ea tšepe ea carbon, alloy tool steel e na le mocheso o motle oa ho hanyetsa, ho hanyetsa ho apara le ho sebetsa hantle. Thempereichara e thibelang mocheso ke 300 ℃-400 ℃, e loketseng ho etsa li-blade tsa boleng bo holimo tsa alloy circular saw.
4. Lisebelisoa tsa tšepe tse lebelo le phahameng li na le boima bo botle, bo thata bo matla le bo thata, le ho senyeha ho fokolang ha mocheso. Ke tšepe e matla haholo e nang le thermoplasticity e tsitsitseng 'me e loketse ho etsa li-blade tsa sakha tse tšesaane tse nang le boleng bo botle.
