Maupangiri Okwanira pa Zogwiritsira Ntchito Zida Zowotcha: Kuchokera ku Mfundo za Thermodynamic mpaka Kukonza Zolondola za Sub-millimeter (2025 Practical Guide)
Kuwulula Chinsinsi cha 0.02mm Runout Precision: Malamulo Khumi Ogwiritsa Ntchito Makina Ochepetsa Kutentha ndi Njira Zowirikiza Moyo Wawo.
Ndemanga ya Nkhani:
I. Thermodynamic fundamental theory yomwe imakhudzidwa ndi makina ochepetsera kutentha: Kugwiritsa ntchito mfundo yokulitsa matenthedwe ndi kutsika pakuchepetsa kwa zida.
1.Key Data mu Sayansi Yazinthu:
Alloy thermal expansion coefficient of thermo:
Chitsulo chochepetsera kutentha kwachitsulo chogwirira ntchito: α ≈ 11 × 10⁻⁶ / ℃ (chimakula ndi 0.33mm kutentha kumakwera ndi 300℃)
Chogwiritsira ntchito: α ≈ 5 × 10⁻⁶ / ℃
Kusokoneza koyenera kupanga:
ΔD=D0 . α. ΔT
Chitsanzo: Chitsulo cha φ10mm chimatenthedwa mpaka 300 ℃ → Bowolo limakula ndi 0.033mm → Mukazizira
Pezani chilolezo choyenera cha 0.01 - 0.03mm
2.Kufanizira Ubwino Waukadaulo Wa Makina Otsitsa Kutentha:
| Clamping Njira | Diameter Runout | Kutumiza kwa Torque | Kuchuluka kwa Ntchito |
| Shrink Fit Holder | ≤3 | ≥100 | 50,000+ |
| Hydraulic Tool Holder | ≤5 | 400-600 | 35,000 |
| ER Spring Collect | ≤10 | 100-200 | 25,000 |
II. Njira yokhazikika yogwiritsira ntchito makina ochepetsa kutentha
Gawo 1: Kutentha kwa makina ochepetsera kutentha
1.Parameter kukhazikitsa ndondomeko yagolide: Tset = α. D0ΔDtarget +25℃
Zindikirani: 25 ℃ imayimira malire achitetezo (kupewa kubwezeredwa kwa zinthu)
Mwachitsanzo: H6 kalasi kusokoneza kokwanira 0.015mm → Set kutentha ≈ 280 ℃
2.Masitepe ogwiritsira ntchito makina ocheperako
Ikani chida → Lowetsani chosungira mu makina ochepetsa kutentha
↓
Khazikitsani kutentha/nthawi
↓
Sankhani mtundu wa chosungira mu makina ocheperako
↓
Ngati chofukizira chapangidwa ndi chitsulo, kusankha kuli motere: 280 - 320 ℃ / 8 - 12 masekondi.
Ngati ntchito aloyi zitsulo chogwirira: 380 - 420 ℃ / 5 - 8 masekondi
↓
Chenjezo la Shrink Fit Machine buzzer → Chotsani chosungira
↓
Woziziritsidwa ndi mpweya / Woziziritsidwa ndi madzi pansi pa 80 ℃ (Awa ndi makina athu ochepetsa kutentha kwa mpweya:Shrink Fit Machine, makina otenthetsera kutentha kwamadzi oziziritsa ndi madzi kupanga ndi kuyesa kukuchitika mufakitale.)
↓
Opaleshoni pamakina ocheperako ikamalizidwa, chizindikiro choyimba chingagwiritsidwe ntchito kuyeza kugwedezeka.
Gawo 2: Kugwiritsa Ntchito Mwadzidzidzi kwa Makina Ocheperako
Alamu yotentha mopitirira muyeso: Kuthimitsa magetsi nthawi yomweyo → Chotengera chida chimamizidwa m'chipinda cha gasi kuti chizizire
Kumatira kwa zida: Kutenthetsanso mpaka 150 ℃ kenako gwiritsani ntchito chochotsera chida chapadera kuti mukankhire kunja kwa axially.
III. Upangiri Wozama Pamakina Ochepetsa Mafuta: Kuchokera Pakukonza Kwatsiku ndi Tsiku Kwa Makina Okwanira a Shrink Fit mpaka Kuneneratu Zolakwika
1.Maintenance schedule for Core Components of Shrink Fit Machine
| Shrink Fit Machine Components | Kukonza Tsiku ndi Tsiku | Zoteteza Kwambiri | Kusintha Pachaka |
| Chophimba cha Heater | Chotsani sikelo ya oxide | Muyezo wa mtengo wokana (kupatuka kochepera kapena kofanana ndi 5%) | Bwezeretsani manja a ceramic insulation |
| Sensa ya kutentha | Chitsimikizo chikuwonetsa cholakwika (± 3 ℃) | Kuwongolera kwa thermocouple | Sinthani module yoyezera kutentha kwa infrared |
| Kuzizira System | Onetsetsani kuti kuthamanga kwa gasi ndi ≥0.6MPa | Chotsani zipsepse zowononga kutentha | Bwezerani chubu chamakono cha shrink fit machine |
2.Strategy yotalikitsa moyo wa omwe ali ndi zida zocheperako
Kuyang'anira kuchuluka kwa matenthedwe:
Kutalika kwa nthawi ya chogwiritsira ntchito: ≤ 300 → Mukadutsa malire awa, kuuma kumatsika mpaka HRC5. Chidule cha fomu yolembera: Chotsani ID | Tsiku | Kutentha | Cumulative Count
Chithandizo cha Shrink fit Holder Restress:
Pambuyo pa mizungu 50 iliyonse → gwirani pa 250 ℃ kwa ola limodzi kuti muchepetse kutentha kosalekeza → chotsani ma microcracks
IV. Tsatanetsatane wa Chitetezo cha Makina Ochepetsa Kutentha ndi Milandu Yowopsa Kwambiri
1.Zochita Zapamwamba Zinayi ndi Zosachita Pogwiritsira Ntchito Shrink Fit Machine:
Chotsani chogwirira ndi dzanja (pamafunika pliers zosagwira kutentha kwambiri)
Kuzimitsa madzi kuziziritsa (kungolola kuziziritsa)
Kutenthetsa kupitirira 400 ℃ kuti aumitse aloyi (zomwe zimapangitsa kuti tirigu akhwime ndi kuthyoka kwa tsamba)
2. Kuwunika kwa Zolakwa Zogwiritsa Ntchito Makina a Shrink Fit Machine:
Chochitika chaphulika pafakitale yamagalimoto:
Chifukwa: Madzi otsalira odulira kuchokera pachosungira chida chocheperako → Kutentha kumayambitsa kuphulika ndi kuphulika
Miyezo: Onjezani malo oyeretserapo omwe ali ndi zida zocheperako + chowunikira chinyezi
V. Mawonekedwe Ogwiritsa Ntchito ndi Zosankha Zosankha Pamakina a Shrink Fit:
| Mtundu wa Njira | Mtundu Wogwirizira Wovomerezeka | Shrink Fit Machine Configuration |
| Aerospace titaniyamu alloy | Chonyamula chida cha carbide chachitali komanso chowonda | Kutentha kwapang'onopang'ono kwapang'onopang'ono (pamwamba pa 400 ℃) |
| Mkulu - liwiro mwatsatanetsatane chosema wa zisamere pachakudya | Chophimba chachifupi chachitsulo cha conical | Kutentha kwa infuraredi (320 ℃) |
| Kuchulukirachulukira | Chogwirizira Chitsulo (BT50) | Electromagnetic induction + Madzi ozizira |
Ngati mukufuna kugula makina ocheperako, mutha dinani "Shrink Fit Machine"kapena"Shrink Fit Holder" kuti mulowe ulalo ndikuwona zambiri. Kapena mutha kulumikizana nafe mwachindunji.
