Bolt lan Nut kanggo Track Shoe Segment Track Roller Cutting Edge
Ukuran standar kanggo bolt excavator lan nut bisa beda-beda gumantung saka make lan model excavator.Ukuran umum kalebu M12, M16, M20, lan M24.
Langkah-1: Inspeksi & panyimpenan bahan mentah
Bahan baku kanggo bolt diputusake dening desainer adhedhasar aplikasi.Bahan sing bakal digunakake kanggo dipriksa banjur lokasi panyimpenan sing tepat kanggo diidentifikasi supaya ora karat lan jangkoan sing tepat kudu diwenehake.
Langkah-2: Manufaktur bolt Unthreaded / Unfinished
Umume casting lan forging digunakake ing tahap iki. Cara liya uga bisa digunakake:
1. Sintering
2. Prototyping (Rapid)
Langkah-3: mesin CNC
Sawise bagean wis diprodhuksi liwat forging / casting rute, iku banjur machined kanggo dimensi dibutuhake biasane dening CNC.
Operasi sing ditindakake ing kene yaiku: nuding, madhep, grooving.
Langkah-4: Perawatan Panas
Perawatan panas rampung sawise mesin kanggo nggawe fasteners kuwat.Operasi hardening & tempering ditindakake.
Kaping pisanan, hardening ditindakake supaya bolt dipanasake nganti suhu 850-900 ° C lan banjur dipateni ing media pendinginan.
Kapindho, bolt dipanasake maneh kanggo ngasilake bolt sing hardened banget kurang alus, supaya bolt tetep kuwat.Pemanasan maneh ditindakake kanggo nyuda brittleness bolt sing kedadeyan nalika hardening.
Langkah-5: Finishing lumahing
Sabanjure yaiku proses finishing permukaan.Biasane, proses grinding ditindakake kanggo nggawe permukaan luwih alus miturut spesifikasi permukaan.
Langkah-6: Utas Rolling
Sawise proses rampung, gulungan benang ditindakake kanthi rong dies.Siji stasioner lan liyane minangka die obah sing bener-bener menehi tekanan ing bolt lan mbentuk benang.
Langkah-7: Coating
Sawise thread rolling, bolts lan screw fasteners dilapisi kanggo nyegah karat lan karat.Conto sing apik saka lapisan bolt yaiku lapisan geomet ing bolt sing bakal diuji SST (Uji Semprotan Uyah) gumantung saka jumlah jam sing wis ditemtokake.
Mesin sing diarani FISCERSCOPE digunakake kanggo nemtokake ketebalan lapisan bebarengan karo alat ukur ketebalan liyane kayata meter ketebalan lapisan.
Langkah-8: Inspeksi Formulir, Fit & Fungsi:
Sawise kabeh proses rampung, pungkasane bagean kasebut dipriksa.Iku kudu ketemu
1. Tes torsi, SST
2. Fitment karo nut
3. Impact strength (Impact charpy test)
4. Uji kekuatan tarik (%elongation of bolt)
5. inti atose bolt
6. Ketebalan coating
Inspeksi dimensi lsp.
