Yakakwana Nhungamiro Yekupisa Shrink Tool Holders: Kubva kuThermodynamic Misimboti kuenda kuSub-millimeter Precision Maintenance (2025 Inoshanda Inotungamira)
Kuzarura Chakavanzika che 0.02mm Runout Precision: Mitemo Gumi Yekushanda Heat Shrink Machines uye Matanho eKupeta Hupenyu Hwavo.
Tsanangudzo yeChinyorwa:
I. Thermodynamic fundamental theory inosanganisirwa muchina wekupisa kupisa: Kushandiswa kwemusimboti wekuwedzera kwekupisa nekumisikidza mukusunga chombo.
1.Kiyi Dhata muZvinhu Sainzi:
Alloy thermal yekuwedzera coefficient yemubati:
Simbi yekupisa inopfutidza chibatiso chekushandisa: α ≈ 11 × 10⁻⁶ / ℃ (inowedzera ne0.33mm kana tembiricha yakwira ne300℃)
Hard alloy toolholder: α ≈ 5 × 10⁻⁶ / ℃
Interference fit design:
ΔD=D0 . α. ΔT
Muenzaniso: Iyo φ10mm mubato wemudziyo unodziya kusvika 300℃ → Gomba dhayamita rinowedzera ne0.033mm → Mushure mekutonhodza.
Wana kukodzera kubvumidzwa kwe 0.01 - 0.03mm
2.Kuenzanisa kweZvakanakira Heat Shrinking Machine Technology:
| Clamping Method | Diameter Runout | Torque Transmission | Application Frequency |
| Shrink Fit Holder | ≤3 | ≥100 | 50,000+ |
| Hydraulic Tool Holder | ≤5 | 400-600 | 35,000 |
| ER Spring Unganidza | ≤10 | 100-200 | 25,000 |
II. Yakamisikidzwa oparesheni maitiro ekushisa shrink muchina
Chikamu chekutanga: Preheating yemuchina wekupisa kupisa
1.Parameter kuisa fomu yegoridhe: Tset = α. D0ΔDtarget +25℃
Ongorora: 25 ℃ inomiririra muganho wekuchengetedza (kudzivirira zvinhu kudzokororwa)
Eg: H6 giredhi kukanganiswa kukwana 0.015mm → Set tembiricha ≈ 280℃
2.Kushanda matanho e shrink fit machine
Isa chishandiso → Isa chibatiso mumushini wekupisa kupisa
↓
Seta tembiricha/nguva
↓
Sarudza rudzi rwechibatiso mumushini we shrink fit
↓
Kana iyo inobata yakagadzirwa nesimbi, kusarudzwa kunotevera: 280 - 320 ℃ / 8 - 12 masekondi.
Kana uchishandisa alloy simbi mubato: 380 - 420 ℃ / 5 - 8 masekondi
↓
Shrink Fit Machine buzzer yambiro → Bvisa chibatiso
↓
Mhepo-yakatonhorera / Mvura-yakatonhodzwa pazasi 80 ℃ (Uyu ndiwo mhepo-yakatonhorera kupisa shrink muchina:Shrink Fit Machine, mvura-yakatonhodzwa kupisa kupisa muchina kugadzirwa uye kuyedzwa kuri kuitika mufekitori.)
↓
Mushure mekunge kuvhiyiwa pamushini we shrink fit kwapera, chiratidzo chedhiya chinogona kushandiswa kuyera vibration.
Chikamu chechipiri: Emergency Kubata kwe shrink fit Machine
Kuwedzera-tembiricha alarm: Ibva yadzima magetsi ipapo → Chibatiso chinonyudzwa mukamuri inert gasi kuti itonhorere.
Tool adhesion: Ipise zvakare kusvika 150 ℃ uye wobva washandisa yakakosha yekubvisa chishandiso kuisundira kunze axially.
III. Yakadzama Maintenance Guide yeThermal Shrinking Machines: Kubva Kugadziriswa Kwemazuva ese kweShrink Fit Machines kuenda kuFault Prediction.
1.Maintenance Schedule yeCore Components ye Shrink Fit Machine
| Shrink Fit Machine Zvikamu | Daily Maintenance | Kunyanya Dziviriro | Year Overhaul |
| Heater Coil | Bvisa chiyero cheokisijeni | Resistance value kuyerwa (kutsauka kushoma pane kana kuenzana ne5%) | Tsiva iyo ceramic insulation sleeve |
| Tembiricha sensor | Iyo yekusimbisa inoratidza kukanganisa (± 3 ℃) | Calibration ye thermocouple | Simudzira iyo infrared tembiricha kuyerwa module |
| Kutonhodza System | Tarisa kuti gasi mutsetse wekumanikidza iri ≥0.6MPa | Chenesa zvimbi zvekubvisa kupisa | Tsiva eddy yazvino chubhu yemuchina we shrink fit muchina |
2.Strategy yekuwedzera hupenyu hwe shrink fit tool holders
Kutariswa kwehuwandu hwekupisa kwemhepo:
Mewha shrink fit tool holder lifespan: ≤ 300 cycles → Mushure mekupfuura iyi muganhu, kuoma kunodzikira kusvika HRC5. Shrink fit holder rekodhi fomu template: Bata ID | Date | Tembiricha | Cumulative Count
Shrink fit holder stress relief treatment:
Mushure mezve makumi mashanu kutenderera → bata pa 250 ℃ kweawa imwe kuti urambe uchipisa tembiricha → bvisa microcracks
IV. Zvekuchengetedza Manongedzo eKupisa Kudonha Machina uye Inouraya Mhosho Nyaya
1.Top Four Do's and Don'ts for Operating Shrink Fit Machine:
Bvisa mubato neruoko (inoda pliers inodzivirira kupisa kwepamusoro)
Mvura inotonhorera inodzima (inobvumira chete kutonhora)
Kupisa pamusoro pe400 ℃ kuomesa alloy (zvichikonzera kukora kwezviyo uye kutsemuka kweblade)
2. Ongororo yeKukanganisa Kushanda Nyaya dzeShrink Fit Machine:
Chiitiko chekuputika pafekitari yemotokari:
Chikonzero: Yakasara yekucheka mvura kubva kune shrink fit turusi inobata → Kupisa kunokonzera vaporization uye kuputika.
Matanho: Wedzera pre-yekuchenesa workstation ye shrink fit tool hold + detector yekunyorova
V. Mamiriro Ekushandisa uye Sarudzo Mazano eShrink Fit Machines:
| Process Type | Yakakurudzirwa Holder Type | Shrink Fit Machine Configuration |
| Aerospace titanium alloy | Yakareba uye mutete carbide mudziyo inobata | High-Frequency thermal induction heat (pamusoro pe400 ℃) |
| High-speed precision engraving ye molds | Short conical simbi inobata | Infrared kupisa (320 ℃) |
| Overload roughing | Yakasimbiswa simbi inobata (BT50) | Electromagnetic induction + Mvura inotonhorera system |
Kana uine zvirongwa zvekutenga shrink fit muchina, unogona kudzvanya "Shrink Fit Machine"kana"Shrink Fit Holder" kuti uise chinongedzo uye kuona rumwe ruzivo rwakadzama. Kana iwe unogona zvakare kutibata isu zvakananga.
