Isingeniso esifushane nge-Tungsten Carbide Cold Heading Dies

1. Yini i-tungsten carbide heading die?

Ngokuqina okuphezulu namandla okugoba okuphezulu, isihloko esibandayo se-tungsten carbide siyacindezelwa futhi sifakwe i-powder metallurgy. Isetshenziswa kabanzi ekubumbeni nasezinkundleni zokwenza iziqinisi. Izikhala zesihloko se-tungsten carbide die zisetshenziswa njengengxenye eyinhloko okufanele icindezelwe ebhantshini lensimbi. Kuhlanganiswe nejacket yensimbi, i-cold heading die ikwazi ukumelana nokugqoka futhi isebenza kahle, futhi impilo yesevisi iyanda kakhulu.

2. Izimo zokusebenza

Ngaphansi kwamandla omthelela anamandla, ingcindezi yomthelela ye-punch ingafinyelela ngaphezu kuka-2500MPa, ingaphezulu le-concave liyafa kanye nendawo yokusebenza ye-punch kokubili kungaphansi kokungqubuzana okunamandla, futhi izinga lokushisa elikhiqizwa phezulu liphezulu kakhulu. 300℃. Ngenxa yobuso obungalingani bokuphela bokungenalutho, i-punch izophinde ibe ngaphansi kwengcindezi yokugoba. Isihloko esibandayo sifa ngaphansi komphumela noma izimo zokusebenza eziqinile ezingagugi, ukufana kwazo ukuthi i-carbide enosimende inomthelela omuhle wokuqina, ukuqina kokuphuka, amandla okukhathala, amandla okugoba, nokumelana okuhle nokugqokwa. Ngakho-ke izinsimbi eziningi zakhiwe ngekhanda elibandayo liyafa.

3. Izindlela zokwehluleka eziyinhloko

Ukuguga ngokweqile endaweni yokusebenza ye-convex kanye ne-concave kufa, ukulimala kwe-occlusal, ukuxebuka kwe-groove yendawo, ukucasula noma ukuphuka kwe-punch, ukuvuvukala noma ukuqhekeka kwefa, ukuwa kwemiphetho namakhona, njll.

4. Izidingo zokusebenza

Isihloko esibandayo sithwala umthwalo owenziwe yisihloko, futhi indawo yokusebenza yefasi iyadingeka ukuze ibe nobulukhuni obuphezulu nokumelana nokugqoka, futhi umgogodla unamandla anele kanye nokuqina. Uma ungqimba oluqinile lwesihloko esibandayo lufa luqinile noma lujulile kakhulu, izingxenye zesikhunta zizophulwa; ngokuphambene nalokho, indawo yokusebenza yezingxenye zesikhunta kulula ukugqoka, futhi izinto ezilukhuni zinamathela ezingxenyeni zesikhunta. Ngokuvamile, ukuqina kwe-punch kungu-60~62HRC, ukufa kungama-58~60HRC, futhi ukujula kongqimba oluqinile kufanele kulawulwe ngu-1.5~4mm. Ifa lesihloko esibandayo lingaphansi kwemithwalo enzima yokunyathela, futhi ingaphezulu lefasi lingaphansi kwengcindezi ephezulu yokucindezela. I-mold material iyadingeka ukuze ibe namandla aphezulu, ukuqina, nokumelana nokugqoka.

I-Zhuzhou Better Tungsten Carbide Company isikhiqize i-tungsten carbide eshona ngaphezu kweminyaka eyi-15. Sinezinkulungwane zamasethi esikhunta ukukhiqiza i-carbide heading ehlukene iyafa.
