1. Kufunga Zvinhu
1. High-Simba Alloy simbi: Kazhinji shandisa high-carbon simbi (semuenzaniso, 4140, 42CrMo4) kana alloy simbi (semuenzaniso, 30Mn5) nokutimabhawa endegekusimba uye kupfeka kusagadzikana.
2. Kuoma & Kuoma: Kuomesa nyaya (semuenzaniso, carburizing) yekuoma kwepamusoro kunyanya mazano ekubhururuka kwendege (55-60 HRC) ine core yakaoma. Kudzima uye kupisa kuenzanisa simba uye kushanduka.
3. Abrasion Resistance: Zvinowedzerwa zvakaita sechromium kana boron zvinowedzera kupfeka kusamira pakurwisana nemarasha/dombo abrasion.
4. Corrosion Resistance: Coatings (semuenzaniso, zinc plating) kana simbi isina tsvina munzvimbo dzinoora.
5. Weldability: Low-carbon variants kana pre/post-weld kupisa mishonga kudzivirira brittleness.
2. Forging Process
1. Method: Yakavharwa-kufa kudonhedza forging for grain flow alignment, inosimudzira kuvimbika kwechimiro. Dzvanya forging kuti uwane chaiyo mune yakaoma zvimiro.
2. Kupisa: Mabhiridha anopisa kusvika 1100-1200 ° C (yesimbi) kuti ave nechokwadi chekugadzirisa.
3. Post-Forging Treatment:
4. Normalizing kubvisa kushushikana.
5. Kudzima (mafuta / mvura) uye kupisa (300-600 ° C) nokuda kwekuoma kwaunoda.
6. Machining: CNC machining kune chaiyo tolerances (± 0.1 mm).
7. Surface Enhancement: Shot blasting kuti iite compression stress uye kuderedza kuneta.
3. Kuongorora & Kuedza
1. Visual & Dimensional Checks: Ongorora kuputika / kukanganisa; shandisa calipers/CMM kune dzakakomba zviyero (ukobvu, gomba kurongeka).
2. Kuedza Kuoma: Rockwell C chiyero chepamusoro, Brinell yepakati.
3. NDT: Magnetic Particle Inspection (MPI) nokuda kwekukanganisa kwepamusoro; Ultrasonic Testing (UT) yekuremara kwemukati.
4. Kuedzwa Kwemutoro (kana zvichibvira): Shandisa 1.5x kushanda mutoro kuti usimbise kuvimbika.
5. Tensile test: necouponi kubva kune imwechete zvinhu uye forging process uye kupisa-kurapwa nemabhawa endege, zvichienderana nemuenzaniso wekuyedza uye / kana kukanganisa bvunzo.
6. Metallurgical Analysis: Microscopy kutarisa zviyo zvezviyo uye kuumbwa kwechikamu.
7. Certification: Kutevedzera ISO 9001/14001 kana ASTM zviyero.
4. Crucial Gungano Points pamwe Mining Chains & Sprockets
1. Kurongeka: Shandisa laser alignment tools kuti uone <0.5 mm / m kutsauka; kukanganisa kunokonzera kusaenzana kwe sprocket kupfeka.
2. Tensioning: Zvakakwanaround link chaintension (semuenzaniso, 1-2% elongation) kudzivirira kutsvedza kana kushushikana zvakanyanya.
3. Lubrication: Isa high-pressure girisi kuderedza friction uye kudzivirira galling.
4. Sprocket Engagement: Matchsprocketzino profile (semuenzaniso, DIN 8187/8188) kune migodhi cheni pitch; ongorora kupfeka (> 10% kuonda kwezino kunoda kutsiviwa).
5. Kusunga: Torque mabhaudhi kune vanogadzira specs (semuenzaniso, 250–300 Nm yeM20 mabhaudhi) ane shinda-kukiya makomisheni.
6. Pre-Assembly Checks: Dzorera sprockets dzakasakara / mining chain links; iva nechokwadi chekubhururuka nebhawa spacing machisa dhizaini yekufambisa.
7. Post-Assembly Testing: Mhanya pasi pemutoro (2-4 maawa) kuti utarise kudengenyeka kusina kujairika / ruzha.
8. Environmental Factors: Chisimbiso majoini kurwisa marasha guruva / unyoro ingress.
9. Monitoring: Isa maIoT sensors echokwadi-nguva yekutevera yekunetsana, tembiricha, uye kupfeka.
5. Maintenance & Training
1. Kudzidziswa kweVashandi: Simbisa kubata kwakakodzera, torque maitiro, uye nzira dzekugadzirisa.
2. Predictive Maintenance: Regular thermographic scans uye vibration kuongorora kuti preempt kukundikana.
Nekugadzirisa zvinhu izvi,mabhawa endegeinogona kuwedzera kushanda kweAFC/BSL, kuderedza nguva, uye kuwedzera hupenyu hwesevhisi munzvimbo dzinodiwa dzemigodhi.
