High -Quality Precision Hlau Tuag Tsim Rau Kev Cai Stamping Tuag

I. Cov yam ntxwv thiab cov teeb meem ntawm Dynamic Loads nyob rau siab -Speed ​​​​Stamping tuag

High -Speed ​​stamping ceev yog ntau dua los yog sib npaug li 50 cycles/feeb. Cov tuag yog raug blanking quab yuam, dabtsi yog khoov quab yuam, thiab tensile quab yuam, ib txhij compounded los ntawm kev vibration thiab thermal stress coupling. Lub dynamic load hloov sai heev thiab complexly faib. Kev tswj tsis zoo tuaj yeem ua rau qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw stamped, nce elastic deformation ntawm cov tuag, thiab lub neej txo qis dua 30%. Yog li ntawd, qhov tseeb dynamic load tsom xam thiab optimization tsim yog lub hauv paus rau txoj kev loj hlob ntawm high - ceev stamping tuag.

II. Dynamic Load Optimization Design Strategies

1. Enhanced Die Structural Rigidity: Siv finite element tsom xam software los simulate dynamic stamping txheej txheem, lub hauv paus tuag thiab reinforcing rib qauv yog optimized, thiab lub thickness ntawm tseem ceeb kev nyuaj siab - bearing qhov chaw yog nce los txhim kho tag nrho rigidity thiab tswj elastic deformation nyob rau hauv 0.01mm. Cov tuag yog ua los ntawm H13 thiab SKD11 siab- lub zog alloy steel, nqus tsev quenched thiab cryogenically kho kom ua tau ib tug hardness ntawm HRC58-62, kev txhim kho load- bearing muaj peev xwm thiab hnav tsis kam, thiab txhim khu lub dynamic load-bearing muaj peev xwm.

2. Optimized Punch thiab Die Fit Tsim: Qhov kev tshem tawm ntawm cov punch thiab tuag yog teem rau ntawm 5% -8% ntawm cov khoom tuab, nrog qhov yuam kev tsawg dua lossis sib npaug ntawm 0.005mm. Kev txhim kho blanking tsim tau txais, nrog rau 0.2-0.3mm hloov lub vojvoog ntawm lub punch txiav ntug kom txo tau qhov cuam tshuam tam sim ntawd, txo qis kev vibration thiab kev poob siab yoj kis tau tus mob, ua tiav cov load nce, xyuas kom ruaj khov, thiab tiv thaiv kev tuag jamming thiab chipping.

3. Dynamic Stress Distribution Uniformity: Lub damping roj hmab ncoo nrog lub thickness ntawm 5-8mm yog ntsia nruab nrab ntawm lub hauv paus tuag thiab lub worktable, los yog ib tug elastic buffer qauv nrog ib tug tsis muaj zog stroke ntawm 1-2 hli yog ntxiv rau tus Tsov tus tw ntawm lub punch los txhim kho kev nyuaj siab concentration, txo ncov kev nyuaj siab los ntawm 20% -30%, lub sij hawm loading uniformity.

4. Kev Tshawb Fawb Kev Tshawb Fawb thiab Kev Tswj Xyuas Kev Ruaj Ntseg: Lub siab thiab kev vibration sensors tau nruab rau ntawm qhov tuag punch thiab tuag tuav los saib xyuas cov khoom siv tsis zoo thaum lub sij hawm stamping txheej txheem ntawm lub sijhawm, thiab cov ntaub ntawv tau muab tso rau hauv kev tswj xyuas ntse. Thaum thauj khoom hloov pauv ntau dua ± 5% lossis kev vibration zaus tshaj tus qauv, lub kaw lus cia li ceeb toom thiab kaw, coj cov neeg ua haujlwm los kho qhov ntsuas kom ntseeg tau tias cov pwm ua haujlwm zoo.

III. Stamping Process Stability Control Methods

1. Cov txheej txheem Parameter Optimization: Raws li cov khoom thickness thiab hardness, txiav txim siab stamping ceev mus rau 50-120 zaug / feeb, nrog stamping quab yuam yuam kev tsawg dua los yog sib npaug rau ± 5% thiab stroke positioning raug tsawg dua los yog sib npaug rau 0.01mm, ua tiav ib tug du kev hloov thaum lub sij hawm stamping txheej txheem thiab tsis txhob oversurge de ua hauj lwm. Precisely tswj lub stamping atherosclerosis, ua kom lub pwm kaw lub sij hawm ntawm 0.1-0.2 vib nas this los txhim kho cov txheej txheem repeatability.

2. Txhim kho Lubrication Conditions: Siv lub siab - stamping ceev - cov roj nplua nyeem tshwj xeeb, ua ntej cov dej qis qis - viscosity -raws li lubricants, tswj cov coefficient ntawm kev sib txhuam kom nyob rau hauv 0.1. Nruab nrog lub tshuab lubrication ntse uas tuaj yeem txau cov roj nplua nyeem raws li lub voj voog stamping, rov ua dua txhua 30-50 daim, txo cov kev sib txhuam tsis sib haum thiab cov cua sov, ua kom ruaj khov dynamic loads, tiv thaiv pwm nto, thiab xyuas kom meej tias qhov ntev ntawm qhov siab ntawm stamped qhov chaw yog tsawg dua los yog sib npaug rau ± 0.02mm uas tsis muaj ntog.

3. Cov Khoom Siv Khoom Siv Kho Kom Zoo: Kho qhov nrawm nrawm thiab qhov ntsuas siab rau cov khoom ua haujlwm ua los ntawm cov khoom sib txawv xws li siab - lub zog steel thiab aluminium alloys. Lub stamping ceev rau siab - lub zog steel yog tswj ntawm 50-80 strokes / feeb, thiab rau txhuas alloys ntawm 80-120 strokes / feeb. Ua kom zoo tshaj qhov tuag tshem tawm thiab txiav ntug tsim raws li cov khoom siv plasticity thiab elasticity kom ntseeg tau tias cov khoom sib txawv deformation thiab tsis txhob muaj kev ntxhov siab.

4. Kev Tswj Xyuas Kev Ua Haujlwm Zoo: Muab kev cob qhia cov txheej txheem tsis tu ncua rau cov neeg ua haujlwm, yuav tsum tau xeem dhau qhov kev ntsuam xyuas ua ntej tso cai rau lawv ua haujlwm, yog li txhim kho cov txheej txheem tswj thiab kev muaj peev xwm teb thaum muaj xwm txheej ceev. Tsim kom muaj cov txheej txheem stamping xyuas cov ntaub ntawv sau cov txheej txheem tsis thiab tuag xwm txheej. Ua ib qho kev kho dua tshiab ntawm cov tuag txhua 100,000 lub voj voog, hloov cov khoom hnav kom ruaj khov thiab ua haujlwm tau zoo.
