Nov yog peb lub ntsiab lus tseem ceeb txog kev nce qib tuag ncab tuag; peb pom zoo kom txuag qhov no!

Kev lag luam pwm suav nrog ntau yam khoom lag luam, nrog rau kev kos duab tuag yog ib qho kev xav tau tshaj plaws. Qhov nyuaj ntawm kev kos duab tuag yog nyob rau hauv ob qhov tseem ceeb: 1) tsim kev suav, thiab 2) sim molding tom qab tsim tiav.

Rau cov neeg tsim qauv, suav nrog ntau yam kev tsim qauv yog qhov tseem ceeb los tsim kom muaj cov qauv kos duab tsim nyog.

Qhov zoo ntawm qhov kos yog inextricably txuas rau cov khoom nws tus kheej, kev xaiv ntawm xovxwm, thiab lubrication.

Kev xaiv cov khoom siv kos duab: 08 steel yog thawj tus neeg sawv cev. Kev kos duab tuag feem ntau yog siv txias- dov steel series xws li 08Al, 08, 08F, 10, 15, thiab 20. Rau cov neeg tsim qauv, xaiv cov khoom tsim nyog yog ib nrab ntawm kev sib ntaus sib tua yeej.

Muab xam txiav Dimensions: Rau rotating thiab cylindrical sib sib zog nqus- kos qhov chaw, txiav qhov ntev yog xam raws li lub hauv paus ntsiab lus ntawm cov khoom ntim tas li. Txawm hais tias cov khoom thins thaum lub sij hawm kos duab, lub ntim tag nrho tseem tsis hloov.

Txoj kev suav rau txoj kev sib tw- cov khoom kos duab yog qhov nyuaj dua vim tias lawv cov duab yog nrog los ntawm kev hloov pauv ntawm cov khoom tuab. Txawm tias muaj kev pab ntawm 3D software thiab simulation tsom xam software, ua tiav cov kev txiav txim siab yog qhov nyuaj. Txhawm rau kom tau txais qhov tsim nyog blanking qhov ntev, ib qho kev sim txiav yog tsim nyog los txiav txim siab txog cov khoom siv uas xav tau. Raws li qhov no, cov qauv ntawm kev ncab tuag tuaj yeem tsim tau, thiab kev sim tsis tu ncua tuaj yeem ua tiav.

Lub stretching coefficient txiav txim seb tus naj npawb ntawm cov kauj ruam yuav tsum tau rau stretching cov khoom, thiab lub stretching qhov siab thiab qhov loj ntawm txhua kauj ruam yog xam siv lub stretching coefficient. Cov qauv sib txawv thiab cov txheej txheem sib txawv ua rau muaj qhov sib txawv ntawm cov txheej txheem stretching, yog li nws yog ib qho tsim nyog los xaiv qhov tsim nyog raws li cov khoom siv tiag tiag.

Lub ntsiab yam tseem ceeb cuam tshuam rau stretching coefficient yog:

1. Cov khoom siv kho tshuab (yield zog-elastic deformation; tensile zog- yas deformation; elongation; txo qhov chaw).

2. txheeb ze thickness ntawm cov khoom.

3. Tus naj npawb ntawm stretching hla.

4. Txoj kev ncab.

5. Lub kaum sab xis ntawm lub punch thiab tuag.

6. Nto tiav thiab lubrication tej yam kev mob ntawm stretching ua hauj lwm nto, clearance, thiab lwm yam.

7. Stretching ceev.

Lub stretching coefficient yog qhia nyob rau hauv daim duab hauv qab no. Yog tias cov kab nrib pleb tshwm sim hauv qhov kev sim tuag, sim siv cov roj nplua nyeem me me (cov roj rapeseed, dej soapy) mus rau qhov tuag qis lossis npog cov khoom siv tuag nrog cov zaj duab xis nyias kom ua tiav cov txiaj ntsig. Kev kho cua sov kom zoo tuaj yeem txhim kho plasticity ntawm cov ntaub ntawv, yog li txo qhov tshwm sim ntawm ntau yam teeb meem tensile nyob rau hauv qhov chaw raug rov qab stretching, uas ua rau hardening tom qab txhua stretch thiab ib tug txo nyob rau hauv plasticity.
