Unveiling the Secret of 0.02mm Runout Precision: Kaum Txoj Cai rau Kev Ua Haujlwm Thaum tshav kub kub Shrink tshuab thiab cov tswv yim rau ob npaug rau lawv lub neej
Nqe lus piav qhia:
I. Thermodynamic fundamental theory muab kev koom tes nyob rau hauv lub tshav kub shrink tshuab: daim ntawv thov ntawm lub hauv paus ntsiab lus ntawm thermal expansion thiab contraction nyob rau hauv lub cuab tam clamping
1. Cov ntaub ntawv tseem ceeb hauv Materials Science:
Alloy thermal expansion coefficient ntawm tus tuav:
Steel tshav kub shrinkable cuab tam kov: α ≈ 11 × 10⁻⁶ / ℃ (exands 0.33mm thaum kub nce los ntawm 300 ℃)
Hard alloy toolholder: α≈ 5 × 10⁻⁶ / ℃
Interference haum tsim:
ΔD = 0. α. Δ T
Piv txwv: Lub φ10mm lub cuab tam kov yog rhuab mus rau 300 ℃ → Lub qhov taub expands los ntawm 0.033mm → Tom qab txias
Ua kom haum haum ntawm 0.01 - 0.03mm
2.Kev sib piv ntawm qhov zoo ntawm tshav kub Shrinking Tshuab Technology:
| Txoj Kev Clamping | Txoj kab uas hla Runout | Torque Transmission | Daim ntawv thov zaus |
| Shrink Fit Holder | ≤ 3 | ≥100 | 50,000+ |
| Hydraulic Tool Holder | ≤ 5 | 400-600 | 35,000 ib |
| ER Caij nplooj ntoos hlav sau | ≤10 | 100-200 | 25,000 ib |
II. Standardized txheej txheem kev khiav hauj lwm rau lub tshav kub shrink tshuab
Theem 1: Preheating ntawm lub tshav kub shrink tshuab
1.Parameter teeb golden formula: Tset = α. D0 Δ Lub hom phiaj + 25 ℃
Lus Cim: 25 ℃ sawv cev rau cov npoo kev nyab xeeb (kom tiv thaiv cov khoom rov qab)
Piv txwv li: H6 qib cuam tshuam haum 0.015mm → Teem kub ≈ 280 ℃
2.Operating cov kauj ruam ntawm lub shrink haum tshuab
Txhim kho lub cuab yeej → Ntxig tus tuav rau hauv lub tshuab ua kom sov
↓
Teem kub / sijhawm
↓
Xaiv hom tuav hauv lub shrink haum tshuab
↓
Yog tias tus tuav yog ua los ntawm cov hlau, kev xaiv yog raws li nram no: 280 - 320 ℃ / 8 - 12 vib nas this
Yog tias siv cov hlau alloy steel kov: 380 - 420 ℃ / 5 - 8 vib nas this
↓
Shrink Fit Tshuab buzzer ceeb toom → Tshem tawm tus tuav
↓
Cua txias / Dej txias hauv qab 80 ℃ (Qhov no yog peb lub tshuab cua txias cua txias:Shrink Fit Tshuab, dej-txias cua sov shrink tshuab kev tsim khoom thiab kev sim yog tab tom ua hauv lub hoobkas.)
↓
Tom qab kev ua haujlwm ntawm lub tshuab shrink haum ua tiav, lub ntsuas ntsuas tuaj yeem siv los ntsuas qhov kev vibration.
Theem 2: Kev Kho Thaum Muaj Xwm Ceev ntawm shrink haum Machine
Tshaj-kub tswb: Tam sim ntawd txiav tawm fais fab mov → Lub cuab tam tuav yog immersed nyob rau hauv lub inert gas chamber kom txias.
Cov cuab yeej adhesion: Kub nws dua rau 150 ℃ thiab tom qab ntawd siv cov cuab yeej tshwj xeeb tshem tawm kom thawb nws tawm axially.
III. Deep Maintenance Guide for Thermal Shrinking Machines: Los ntawm Kev Kho Txhua Hnub ntawm Cov Tshuab Shrink Fit rau Kev Ua Phem
1.Maintenance Schedule rau Core Cheebtsam ntawm Shrink haum tshuab
| Shrink Fit Tshuab Cheebtsam | Kev tu txhua hnub | Kev tiv thaiv heev | Kev Txhim Kho Txhua Xyoo |
| Cua sov Coil | Tshem tawm cov nplai oxide | Kev ntsuas tus nqi tiv thaiv (kev sib txawv tsawg dua lossis sib npaug li 5%) | Hloov lub tes tsho ceramic insulation |
| Kub sensor | Kev txheeb xyuas pom qhov yuam kev (± 3 ℃) | Calibration ntawm thermocouple | Txhim kho qhov ntsuas kub infrared module |
| Txias System | Xyuas tias cov roj kab siab yog ≥0.6MPa | Ntxuav cov cua kub dissipation fins | Hloov lub eddy tam sim no raj ntawm lub shrink haum tshuab |
2.Strategy rau ncua lub neej ntawm shrink haum tuav tuav
Kev soj ntsuam ntawm tus naj npawb ntawm thermal cycles:
Mewha shrink haum cov cuab yeej tuav lub neej: ≤ 300 cycles → Tom qab dhau qhov kev txwv no, lub hardness txo mus rau HRC5. Shrink haum tuav daim ntawv template: Kov ID | Hnub tim | Kub | Suav suav
Shrink haum tuav txoj kev kho kev ntxhov siab:
Tom qab txhua 50 cycles → tuav ntawm 250 ℃ rau 1 teev rau qhov kub thiab txias annealing → tshem tawm microcracks
IV. Kev nyab xeeb Specifications rau cua sov Shrinking tshuab thiab tuag yuam kev Case
1.Top Four Do's and Don'ts for Operating a Shrink Fit Machine:
Tshem tawm ntawm tes (yuav tsum muaj cov pliers kub-resistant)
Dej txias quenching (tsuas yog tso cai kom txias)
Cua sov ntawm tshaj 400 ℃ kom tawv tawv (ua rau nplej coarsening thiab hniav tawg)
2. Kev soj ntsuam ntawm kev ua haujlwm yuam kev ntawm lub tshuab Shrink Fit:
Ib qho xwm txheej tawg ntawm lub tuam txhab tsheb:
Yog vim li cas: Cov kua dej seem seem ntawm lub shrink haum cov cuab yeej → Cua sov ua rau vaporization thiab tawg
Kev ntsuas: Ntxiv ib qho chaw ua haujlwm tu ua ntej rau lub thawv ntim khoom ntim + lub ntsuas dej noo
V. Daim ntawv thov Scenarios thiab xaiv cov lus qhia rau Shrink Fit Machine:
| Hom txheej txheem | Pom zoo Holder Hom | Shrink Fit Machine Configuration |
| Aerospace titanium alloy | Ntev thiab slender carbide cuab yeej tuav | High-Frequency thermal induction cua sov (siab tshaj 400 ℃) |
| High-speed precision engraving ntawm pwm | Short conical steel tuav | Infrared cua sov (320 ℃) |
| Overload roughing | Muaj zog steel tuav (BT50) | Electromagnetic induction + Dej txias system |
