Kev tsis xws luag thiab kev daws teeb meem ntawm stretching tuag

1. Deformation ntawm Flanged thiab tsim qhov chaw

Deformation feem ntau tshwm sim thaum lub sij hawm flanging thiab tsim txheej txheem. Hauv qhov tsis yog- qhov chaw saum npoo, qhov no feem ntau tsis cuam tshuam rau qhov zoo. Txawm li cas los xij, hauv qhov chaw saum npoo, txawm tias me ntsis deformation tuaj yeem ua rau muaj qhov tsis zoo, cuam tshuam rau tag nrho lub tsheb zoo.

Ua rau:

1. Thaum lub sij hawm tsim thiab flanging, cov ntawv hlau deforms thiab ntws. Yog tias lub zog clamping tsis txaus, deformation yuav tshwm sim.

2. Txawm tias muaj zog clamping txaus, tsis sib npaug ntawm qhov clamping nto, ua rau muaj qhov khoob, kuj tuaj yeem ua rau cov xwm txheej saum toj no.

Kev daws:

1. Ua kom lub zog clamping. Yog tias siv lub caij nplooj ntoos hlav clamping, ntxiv lub caij nplooj ntoos hlav. Rau huab cua- cov khoom siv cushion clamping, ua kom lub cushion quab yuam.

2. Yog tias qhov deformation tseem nyob tom qab nce siab, siv cov hlau lead ua rau pom qhov teeb meem. Tshawb xyuas cov kev nyuaj siab hauv zos ntawm qhov chaw clamping. Nyob rau hauv tas li ntawd, weld lub clamping phaj.

3. Tom qab welding, lapped lub phaj clamping tiv thaiv qis pwm nto.

2. Ntug chipping Edge chipping tshwm sim los ntawm ntau yam laj thawj thaum siv pwm yuav cuam tshuam rau qhov zoo ntawm cov khoom tsim. Nws yog ib qho ntawm cov kev kho ntau tshaj plaws hauv kev kho pwm. Cov kauj ruam kho rau ntug chipping yog raws li nram no:

1. Nyob ntawm seb qhov luaj li cas ntawm cov chipping, yog tias qhov chipping me me, qhov chipped cheeb tsam feem ntau yuav tsum yog hauv av loj dua nrog lub log sib tsoo kom ntseeg tau tias muaj zog vuam thiab tiv thaiv kev sib tsoo ntxiv;

2. Weld siv cov vuam vuam uas tsim nyog. Tam sim no, peb siv D332 vuam rods rau welding ntug. Ua ntej vuam, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov chaw siv rau kev kho, nrog rau qhov chaw tshem tawm thiab qhov tsis yog - clearance nto;

3. Smooth lub non- clearance nto ntawm ntug (saib rau lub pre-tsim siv);

4. Kos qhov kev hloov pauv. Yog tias tsis muaj qhov hloov pauv, qhov chaw tshem tawm tuaj yeem ua rau thaj av siv ua ntej - tsim los siv;
5. Haum rau qhov chaw tshem tawm ntawm lub tshuab, siv cov av nplaum lossis lwm yam kev pab kom haum. Thaum lub sij hawm kho, yuav tsum tau ceev faj heev. Pib cov xovxwm kom maj mam li sai tau, thiab yog tias tsim nyog, kho qhov siab tuag downwards kom tsis txhob ua rau lub txiav ntug.

6. Qhov txiav ntug clearance yuav tsum tsim nyog. Rau steel phaj stamping tuag, ib zaug - sab txiav ntug clearance yuav tsum yog 1/20 ntawm daim ntawv thickness. Txawm li cas los xij, hauv kev ua haujlwm tiag tiag, qhov loj me tuaj yeem kuaj xyuas los ntawm kev sim stamping nrog cov ntawv hlau. Tsuav qhov burrs ntawm qhov txiav ua tau raws li qhov yuav tsum tau ua, nws yog qhov tsim nyog. Feem ntau, qhov kev ntsuas rau kev txiav txim siab burr loj yog tias qhov siab burr yuav tsum tsis pub tshaj 1/10 ntawm daim ntawv thickness.

7. Tshawb xyuas seb qhov kev tshem tawm ntawm qhov txiav ntug puas yog raws li cov kev taw qhia shearing.

8. Tom qab qhov kev tshem tawm tau raug kho kom zoo, siv cov pob zeb roj kom du qhov chaw tshem tawm ntawm cov ntug txiav kom txo cov kev sib txhuam ntawm cov ntawv hlau thiab cov ntug txiav thaum lub sij hawm tsim khoom thiab kev tiv thaiv ntawm cov khoom poob.

3. Roughness Txiav ntug chipping thiab roughening feem ntau tshwm sim hauv kev kos duab, sib sau, thiab flanging txheej txheem.

Kev daws:

1. Ua ntej, nrhiav qhov sib thooj roughened cheeb tsam ntawm cov pwm los ntawm kev sib piv nrog lub workpiece;
2. Siv cov pob zeb roj kom du qhov chaw sib thooj ntawm cov pwm, ua kom lub vojvoog tsis sib xws;
3. Polish thaj tsam ntawm cov pwm nrog cov ntawv xuab zeb zoo (400 grit lossis siab dua).

4. Trimming thiab Punching Material Traping: Lub ntsiab ua rau trimming thiab xuas nrig ntaus khoom ntxiab yog ib qho txawv txav ntawm pwm lub siab los yog unloading ntaus ntawv thaum trimming los yog xuas nrig ntaus.

Kev daws:

1. Nrhiav qhov chaw sib thooj ntawm cov pwm raws li qhov chaw daig ntawm qhov chaw ua haujlwm;

2. Tshawb xyuas qhov txawv txav ntawm pwm lub siab thiab tshem tawm phaj;

3. Kho qhov chaw sib thooj ntawm lub phaj siab los ntawm vuam;

4. Smooth lub welded cheeb tsam raws li lub workpiece, kom ntseeg tau tias cov profile tshwj xeeb phim cov txheej txheem ib feem;

5. Ua ib qho kev xeem punch;

6. Yog hais tias qhov teeb meem tsis yog nrog pwm lub siab thiab unloading phaj, xyuas cov pwm txiav ntug rau roughening.

5. Cov khoom seem tsis txiav: Hais txog qhov teeb meem ntawm cov khoom seem tsis raug txiav, ua ntej txheeb xyuas vim li cas nws tsis tuaj yeem txiav. Qhov laj thawj tseem ceeb yog tias cov neeg ua haujlwm tsis tau ntxuav cov khoom seem hauv lub sijhawm thaum lub sijhawm tsim khoom, ua rau nws tawg. Thaum kawg, nyob rau hauv lub siab ntawm lub sab sauv trimming hniav, cov khoom seem cutter chipped. Txoj kev kho yog zoo ib yam li ntawd rau chipped trimming hniav, yog li nws yuav tsis qhia meej ntawm no. Txawm li cas los xij, thaum lub sij hawm kho, nws yog ib qho tseem ceeb uas yuav tsum tau them sai sai rau qhov siab ntawm cov hniav trimming. Yog hais tias nws yog trimmed siab dhau lawm, nws yuav ua rau muaj kev cuam tshuam ntawm cov hniav thiab lub sab sauv trimming hniav, ua rau muaj kev puas tsuaj ntxiv rau cov khoom seem cutter. Yog hais tias nws yog trimmed tsawg dhau, cov khoom seem yuav tsis raug txiav. Yog li ntawd, thaum kho cov khoom seem cutters, tsis tsuas yog qhov sib txawv ntawm cov hniav blocks, tab sis kuj yog qhov siab ntawm cov hniav blocks tseem ceeb heev. Kev kho cov khoom seem cutters yog qhov nyuaj dua li tsuas yog kho cov hniav chipped. Txawm li cas los xij, tsuav yog xaiv qhov chaw siv ua ntej kho, kev kho tuaj yeem ua tau zoo.

6. Burrs Cov burrs ntau dhau yuav tshwm sim thaum txiav, xuas nrig ntaus, thiab blanking ntawm qhov chaw. Qhov laj thawj tseem ceeb yog ob npaug: loj thiab me me clearance ntawm qhov tuag txiav npoo.

Loj clearance: Lub ci ci ntawm tus ntoo khaub lig-section yog me me los yog yuav luag tsis pom. Cov burrs yog tuab thiab loj, thiab nyuaj rau tshem tawm.

Kev tshem tawm me me: Ob lub teeb ci ntsa iab tshwm rau ntawm tus ntoo khaub lig-section. Vim qhov me me clearance, cov burrs yog siab thiab nyias.

Kho txoj kev rau loj clearance:

1. Nyob rau hauv trimming thiab xuas nrig ntaus cov txheej txheem, lub punch tseem nyob ruaj ruaj thaum lub tuag raug kho. Hauv cov txheej txheem blanking, qhov tuag yog siv los ua ib qho kev siv, lub ntsiab lus ntawm qhov tuag qhov ntev tseem tsis hloov, thiab cov punch raug kho. Qhov sib txawv no ua kom ntseeg tau tias qhov loj ntawm cov khoom tsis cuam tshuam ua ntej thiab tom qab kho.

2. Nrhiav qhov chaw nrog loj clearance nruab nrab ntawm cov tuag txiav npoo ntawm ib feem.

3. Kho qhov chaw no nrog cov vuam vuam uas tsim nyog (D332) kom ntseeg tau tias qhov tawv tawv ntawm qhov tuag txiav ntug.

4. Kho qhov txiav ntug clearance (siv tib txoj kev raws li chipped txiav ntug). Kho txoj kev rau me me clearance:

1. Kho qhov kev tshem tawm raws li qhov xwm txheej tshwj xeeb kom paub meej tias qhov kev tshem tawm tsim nyog. Rau trimming xuas nrig ntaus tuag, qhov clearance yog muab tso rau hauv lub qhov tuag kab noj hniav, thaum rau blanking tuag, lub punch yog loj los xyuas kom meej qhov seem seem tsis hloov ua ntej thiab tom qab kho.

2. Tom qab kho, ntsuas qhov perpendicularity ntawm qhov chaw clearance thiab sim cov hniav clearance nrog ib daim ntawv hlau los xyuas kom meej tias nws ua tau raws li qhov tsim nyog. Rau kev xuas nrig ntaus tuag, yog tias burrs tshwm sim los ntawm kev hnav ntawm lub punch lossis tuag, hloov lawv nrog cov qauv sib xws. Yog tias tsis muaj cov qauv txheem, kho vuam lossis kev tsim los ntawm kev ntsuas tuaj yeem siv. Tsis tas li ntawd, nws yuav tsum tau muab sau tseg tias rau cov ntaub ntawv uas tsis zoo weldability, xws li hlau alloy, yuav tsum tau tshwj xeeb kev kho mob ua ntej welding, xws li preheating, txwv tsis pub, tuag yuav tawg.

7. Punching Scrap Thaiv
Punching seem blockage yog ib qho txhaum hauv kev xuas nrig ntaus tuag. Cov laj thawj muaj xws li: cov khoom seem tsis sib xws, cov khoom seem tsis sib xws, thiab tsis ua tiav cov khoom seem hauv lub sijhawm. Ua rau:

1. Cov pwm tsis du, nrog cov cim ua haujlwm lossis lwm yam tsis zoo ntawm nws qhov chaw;

2. Cov pwm muaj qhov hloov pauv hloov pauv, ua rau cov seem seem kom dav rau saum toj thiab nqaim hauv qab, ua rau cov khoom seem.

Txoj Kev Kho: Xyuas kom meej tias ob qhov chaw A thiab B yog du thiab sib npaug ntawm txoj kab uas hla yuav tiv thaiv cov khoom seem.
