Nyob rau hauv cov txheej txheem ntawm precision stamping qhov chaw ua, qee zaum nws yuav pom tias qhov chaw stamping muaj qee qhov sib txawv ntawm qhov ntau thiab tsawg, uas muaj qee yam cuam tshuam rau cov khoom zoo. Yog li dab tsi yog qhov ua rau burrs hauv precision stamping qhov chaw?
A. Lub riam ntug yog blunt.
Burrs tuaj yeem tshwm sim yog tias qhov txiav ntug hnav, dulled, lossis gnawed. Cov yam ntxwv uas cuam tshuam rau dullness ntawm txiav ntug yog:
1. Cov khoom siv thiab qhov chaw kho mob ntawm cov kab mob thiab cov kab mob ntawm cov pwm tsis zoo, thiab kev hnav tsis zoo;
2. Cov qauv tuag tsis zoo thiab cov rigidity tsis zoo, ua rau raug mob gnawing;
3. Lubrication tsis raws sijhawm thaum lub sijhawm ua haujlwm, thiab hnav tau nrawm;
4. Lub txiav ntug tsis tau sharpened nyob rau hauv lub sij hawm.
B. Kev tshem tawm.
Burrs tuaj yeem tshwm sim yog tias qhov sib txawv ntawm qhov punching loj dhau, me dhau, lossis tsis sib xws. Cov hauv qab no cuam tshuam qhov sib txawv kom loj dhau, me dhau los yog tsis sib xws:
1. Pwm raug yuam kev, stamping tuag qhov chaw ua tsis ua raws li cov duab kos, qhov sib npaug ntawm cov phaj hauv qab tsis zoo, thiab lwm yam;
2. Pwm sib dhos yuam kev, qhov sib txawv loj ntawm cov lus qhia, convex thiab concave tuag sib dhos miscenter, thiab lwm yam.;
3. Qhov tseeb ntawm cov xovxwm yog qhov tsis zoo, xws li qhov sib txawv ntawm cov kev taw qhia kev tsheb ciav hlau ntawm cov xovxwm yog qhov loj heev, qhov sib npaug ntawm qhov chaw hauv qab ntawm lub slider thiab qhov chaw ntawm lub workbench tsis zoo, los yog qhov perpendicularity ntawm cov hlab ntsha. ntawm lub slider thiab lub rooj xovxwm tsis zoo, lub rigidity ntawm lub workbench yog tsis zoo, thiab lub deflection tshwm sim thaum lub sij hawm blanking, uas yuav ua rau kom qhov kev hloov ntawm qhov sib txawv;
4. Kev teeb tsa yuam kev, xws li qhov saum npoo ntawm daim hlau sab saud thiab sab hauv qab ntawm qhov tuag tsis tau so huv si thaum lub sij hawm installation los yog txoj kev fastening ntawm lub Upper tuag ntawm lub loj tuag yog tsis tsim nyog, thiab lub Upper thiab qis tuag ntawm cov tuag yog tsis ntsia nrog qhov chaw (tshwj xeeb tshaj yog cov ncej uas tsis yog phau ntawv qhia tuag) thiab qhov chaw ua haujlwm yog qaij;
5. Cov qauv ntawm cov punch yog tsis tsim nyog, qhov nruj ntawm qhov tuag thiab qhov chaw ua haujlwm tsis txaus, thiab cov punching quab yuam tsis sib npaug.
6. Lub kaum sab xis ntawm lub phaj hlau yog loj, thiab cov phaj hlau tsis sib xws.
C. Lub xeev xuas nrig ntaus tsis raug
Yog tias qhov khoob (nrog rau cov khoom nruab nrab) tsis zoo nrog cov xuas nrig ntaus lossis tuag, thaum txiav thiab xuas nrig ntaus nrog qhov siab tsis zoo nyob, qhov siab ntawm lub workpiece yuav qis dua qhov sib txheeb qhov siab ntawm qhov chaw, thiab cov duab. ntawm lub workpiece thiab cov duab ntawm lub txiav ntug yuav tsis conformed thiab burrs yuav tshwm sim thaum lub sij hawm blanking txheej txheem.
D. Tsis zoo manufacturability ntawm lub workpiece
Cov duab nyuaj, protruding los yog concave ntse ces kaum yog nquag burrs vim hnav ceev.
E. Cov khoom siv tsis ua raws li cov txheej txheem kev cai
Lub thickness ntawm cov khoom yog tawm ntawm kev kam rau siab los yog cov khoom tsis ncaj ncees lawm (xws li qib hlau tsis raug) ua rau cov txheeb ze clearance tsis tsim nyog, ua rau burrs nyob rau hauv lub workpiece.
