Bolt jeung Nut pikeun Track Shoe Bagéan Track Roller Cutting Edge
Ukuran baku pikeun baud excavator jeung nut bisa rupa-rupa gumantung kana make jeung model excavator nu.Ukuran umum kalebet M12, M16, M20, sareng M24.
Lengkah-1: inspeksi & neundeun bahan baku
Bahan baku pikeun baud diputuskeun ku desainer dumasar kana aplikasi.Bahan anu bakal dianggo pikeun dipariksa teras lokasi panyimpen anu pas kedah diidentifikasi supados ngahindarkeun formasi karat sareng sinyalna anu leres kedah disayogikeun.
Lengkah-2: Unthreaded / Unfinished baud manufaktur
Lolobana casting jeung forging dipaké dina tahap ieu. Métode séjén ogé bisa dipaké:
1. Sintering
2. Prototyping (Rapid)
Lengkah-3: CNC machining
Saatos bagian nu geus dijieun via forging / casting jalur, mangka machined kana dimensi diperlukeun biasana ku CNC.
Operasi anu dituturkeun di dieu nyaéta: nunjuk, nyanghareup, grooving.
Lengkah-4: perlakuan panas
Perlakuan panas dipigawé sanggeus machining sangkan fasteners kuat.Operasi hardening & tempering dituturkeun.
Kahiji, hardening dipigawé saperti baud dipanaskeun nepi ka suhu 850-900 ° C lajeng quenched dina media cooling.
Bréh, baud deui dipanaskeun deui pikeun mawa balik baud hardened ekstrim kirang lemes, ku kituna baud tetep kuat.Pemanasan ulang dilakukeun pikeun nurunkeun brittleness baud anu kajantenan nalika pengerasan.
Lengkah-5: Surface Finishing
Salajengna nyaéta prosés finish permukaan.Biasana, prosés grinding dilumangsungkeun sangkan permukaan smoother nurutkeun spésifikasi finish permukaan.
Lengkah-6: Thread Rolling
Sanggeus prosés rengse, rolling thread dipigawé ku dua maot.Hiji stasioner sareng anu sanésna mangrupikeun paeh anu gerak anu leres-leres masihan tekanan kana baut sareng ngabentuk benang.
Lengkah-7: palapis
Saatos thread rolling, bolts na screw fasteners anu coated guna nyegah karat sarta korosi.Conto anu hadé tina palapis baut nyaéta palapis géomet dina baut anu bakal diuji kana SST (Uji Semprot Uyah) gumantung kana jumlah jam anu ditangtukeun.
Mesin anu disebut FISCHERSCOPE dianggo pikeun nangtukeun ketebalan lapisan sareng alat ukur ketebalan anu sanés sapertos méter ketebalan lapisan.
Lengkah-8: Inspeksi pikeun Bentuk, Pas & Fungsi:
Saatos sadaya prosés parantos dilakukeun, tungtungna bagianna nuju pamariksaan.Ieu kudu papanggih
1.Uji torsi, SST
2.Fitment kalawan kacang
3. Dampak kakuatan (Impact charpy test)
4. Uji kakuatan Tensile (% elongation of bolt)
5.Core karasa baud
6. ketebalan palapis
Inspeksi dimensi jsb.
