Mokhoa oa ho khetha lehare la carbide?

Lehare le entsoeng ka samente ea carbide le na le likarolo tse ngata tse kang mofuta oa hlooho ea alloy cutter, thepa ea motheo, bophara, palo ea meno, botenya, sebōpeho sa leino, angle, bophara ba lesoba, joalo-joalo. bokhoni ba ho sebetsa le ts'ebetso ea ho itšeha ea lehare la sakha. Ha u khetha lehare la sakha, ho hlokahala hore u khethe lehare la sakha ka nepo ho latela mofuta, botenya, lebelo la ho sakha, tataiso ea ho seha, lebelo la ho fepa le bophara ba thepa ea sawing.

(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). Ka lebaka la khanyetsano e ntle ea tungsten le cobalt carbides, li sebelisoa haholo indastering ea ho lokisa lehong. Mefuta e atisang ho sebelisoa ha ho etsoa lehong ke YG8-YG15. Nomoro ka mor'a YG e bontša peresente ea cobalt content. Ka keketseho ea dikahare tsa cobalt, matla a ts'usumetso le matla a flexural a alloy a ntlafatsoa, ​​​​empa ho thatafala le ho hanyetsa ho roala hoa fokotseha. Khetha ho latela boemo ba sebele.

(2) Khetho ea substrate

1.65Mn tšepe ea selemo e na le elasticity e ntle le polasetiki, thepa ea moruo, kalafo e ntle ea mocheso e thata-thata, mocheso o tlase o futhumatsang, deformation e bonolo, 'me e ka sebelisoa bakeng sa mahare a sakha a nang le litlhoko tse tlase tsa ho itšeha.

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 ho 200.℃-250 ℃ mocheso, mocheso pheko deformation ke e kholo, hardenability e futsanehile, 'me tempering nako e telele le bonolo ho peperana. Etsa lisebelisoa tsa moruo bakeng sa lisebelisoa tsa ho seha tse kang T8A, T10A, T12A, joalo-joalo.

3. Ha ho bapisoa le tšepe ea lisebelisoa tsa carbon, tšepe ea alloy e na le mocheso o motle oa ho hanyetsa, ho hanyetsa ho apara, le ts'ebetso e ntle ea ho tšoara.

4. Lisebelisoa tsa tšepe tsa lebelo le phahameng li na le ho thatafala ho hotle, ho thatafala ho matla le ho tiea, le ho senyeha ho fokolang mocheso. Ke tšepe e matla haholo, 'me botsitso ba eona ba thermoplastic bo loketse ho etsa li-saha tsa maemo a holimo tse tšesaane.

(3) Khetho ea bophara

Bophara ba lehare la sakha bo amana le lisebelisoa tsa ho sakha tse sebelisoang le botenya ba mosebetsi oa ho sakha. Bophara ba lehare la saw bo nyenyane, 'me lebelo la ho itšeha le batla le le tlaase; ha bophara ba lehare la sakha bo le khōloanyane, litlhoko tsa lehare la sakha le lisebelisoa tsa ho sakha li phahame, 'me mosebetsi oa ho sakha o phahame. Bophara bo ka ntle ba lehare la saw bo khethoa ho ea ka mefuta e fapaneng ea selikalikoe sa selikalikoe 'me ho sebelisoa lehare la saw le bophara bo tšoanang.

The diameter tsa likarolo tse tloaelehileng ke: 110MM (4 lisenthimithara), 150MM (6 lisenthimithara), 180MM (7 lisenthimithara), 200MM (8 lisenthimithara), 230MM (9 lisenthimithara), 250MM (10 lisenthimithara), 300MM (12 lisenthimithara), 350MM. ( lisenthimithara tse 14), 400MM ( lisenthimithara tse 16), 450MM ( lisenthimithara tse 18), 500MM ( lisenthimithara tse 20), joalo-joalo. The groove saw blades ea ho nepahala phanele saha boholo ba etselitsoe ho ba 120MM.

(4) Khetho ea palo ea meno

Ka kakaretso, ha ho na le meno a mangata, likarolo tse ngata tsa ho itšeha li ka khaoloa ka nako e le 'ngoe,' me ts'ebetso ea ho itšeha e ntlafala. Leha ho le joalo, ha palo ea ho itšeha meno e ntse e eketseha, ho hlokahala carbide e eketsehileng ea samente, 'me theko ea lehare la sakha e phahame, empa meno a teteaneng haholo. , palo ea li-chips pakeng tsa meno e fetoha e nyenyane, e leng bonolo ho etsa hore lehare la saw le futhumale; Ho phaella moo, ho na le meno a mangata haholo a saha, 'me haeba chelete ea lijo e sa tsamaisane hantle, palo ea ho itšeha ea leino le leng le le leng e nyenyane haholo, e leng ho tla mpefatsa likhohlano pakeng tsa ho itšeha le workpiece le ho ama bophelo ba tšebeletso ea ho itšeha. bohale. . Hangata karohano ea meno ke 15-25mm, 'me palo e lekaneng ea meno e lokela ho khethoa ho ea ka thepa e lokelang ho hahoa.

(5) Khetho ea botenya

Botenya ba lehare la saw Ka khopolo, re tšepa hore lehare le tšesaane la saw, le molemo, seam sa saw ha e le hantle ke mofuta oa tšebeliso. Thepa ea alloy saw blade base le ts'ebetso ea tlhahiso ea lehare la sakha li khetholla botenya ba lehare la sakha. Haeba botenya bo le bobebe haholo, lehare la saw le bonolo ho sisinyeha ha le sebetsa, le amang phello ea ho itšeha. Ha u khetha botenya ba lehare la saw, ho lokela ho nahanoa ka botsitso ba lehare la sesepa le thepa e lokelang ho etsoa. Botenya bo hlokehang bakeng sa lisebelisoa tse ling tsa morero o khethehileng le bona bo totobetse, 'me bo lokela ho sebelisoa ho ea ka litlhoko tsa thepa, joalo ka li-saha tsa slotting, li-saha tsa scribing, joalo-joalo.
