Nzira dzekudzikisa Mutswe weCarbide Kucheka Tool

1. Dzora nzira yekudziya yekudzikisa chizvarwa chekutsemuka.

Kana kupisa kwekupisa kunodzorwa kunenge 30-50 ° C yakakwirira kudarika nzvimbo yakanyunguduka ye solder, nzvimbo yakanyunguduka yemutengesi yakasarudzwa inofanira kunge yakaderera kupfuura iyo inonyunguduka ye arbor ne 60 ° C. Munguva yekupisa, murazvo unofanirwa kupiswa zvakaenzana kubva pasi kusvika kumusoro uye zvishoma nezvishoma preheated for brazing. Nokudaro, groove uye carbide blade inodiwa. Iyo brazing surface inopindirana, kupisa kwenzvimbo kuchaita kuti kusiyana kwekushisa pakati peblade pachayo kana blade uye chibatiso chive chikuru, uye kushushikana kwekushisa kuchaita kuti blade iparadze. Murazvo unofanira kutamiswa nekudzoka shure uye mberi kuti upise, kuitira kudzivirira kupisa kwenzvimbo nekutsemuka kunokonzerwa nekuwanda kwekupisa.

2. Mhedzisiro ye sipe shape pakugadzira crack inozikanwa.

Chimiro che groove yebanga hachipindirani nepamusoro pebrazing yebanga shank kana ine mutsauko mukuru, kuumba yakavharwa kana semi-yakavharwa groove chimiro, iyo iri nyore kukonzera yakawandisa brazing pamusoro uye yakawandisa welding layer. Nekuda kwekusapindirana kwe shrinkage rate mushure mekuwedzera kwekupisa, zviri nyore zvakare kune carbide blade brazes kukonzera kushushikana kwakanyanya uye kuumba kuputika. Nharaunda yechiso chebrazing inofanira kuderedzwa zvakanyanya sezvinobvira pasi pemamiriro ekugutsikana kwesimba weld zvinodiwa zvekushandisa.

3. Nyarara pasi zvine hungwaru.

Kurumidza kutonhora panguva kana mushure mekubhuroka uye kushomeka kwemvura yekuyerera kunokonzeresa zviri nyore kuti carbide blade tip iparare uye kutsemuka. Nokudaro, solder inodiwa kuti ive nehutano hwakanaka hwekudzikisa mvura. Mushure mekupisa, haifanirwe kuiswa mumvura kuti ikurumidze kutonhora. Mushure mekutonhora zvishoma nezvishoma mujecha, nezvimwewo, inochengetwa pa300 ℃ kweanopfuura maawa matanhatu uye yakatonhodzwa nechoto.

4. Nyatsoteerera kukanganisa kwekukanganisa pasi pepamusoro pe sipe pakuputika.

Nzvimbo yekubatana pakati peblade nekerf haisi yakatsetseka. Kana paine makomba eganda dema uye zvikonzero zvekusaenzana kwenzvimbo, iyo brazing haigone kuumba jira rakatsetseka, izvo zvinokonzeresa kusaenzana kwekugovera solder, izvo zvisingakanganisi simba re weld chete asiwo zvinokonzeresa kushushikana kwepfungwa, uye zviri nyore Kukonzera blade kuti iparadze, saka blade inofanira kugaya nzvimbo yekubatana, uye nzvimbo yekuputika ye blade groove inofanira kucheneswa. Kana chikamu chetsigiro chemubati wechombo chakakurisa kana chikamu chetsigiro chemubati chisina kusimba, chishandiso chinoiswa pasi pesimba rekumanikidza panguva yekugadzira brazing uye kuparara kuchaitika.

5.Kuteerera kune zvinokonzerwa nekupisa kwechipiri kweblade pakugadzirwa kwekuputika.

Mushure mekunge blade yaputirwa, iyo mhangura yekuzadza simbi haizadzi zvachose gaka, uye dzimwe nguva pachava nekumwe kusungirira, uye mamwe mapanga achadonha kubva pabadza panguva yekubuda muchoto, saka inofanirwa kuve. kudziyisa kaviri. Nekudaro, iyo cobalt binder inopiswa zvakanyanya, uye zviyo zveWC zvinokura, izvo zvinogona kutungamirira zvakananga mukutsemuka kweblade.

Cemented carbide ine kuoma kwakanyanya uye brittleness. Kana iyo brazing process isina hanya, inoraswa nekuda kwekutsemuka. Nzwisisa mapoinzi ekutarisisa paunenge uchibhuroka tungsten carbide yekucheka maturusi kudzivirira kutsemuka.
