Txheem rau embossing qauv tsim ntawm hlau stamping tuag

Siab -High Embossing Forming Method: Siab -qhov siab embossings feem ntau pom ntawm cov khoom xws li MB boards, raws li pom hauv daim duab (A).

Siab -Qhov siab Embossing Forming Method: Qhov siab embossing (H) ntawm cov khoom yog qhov siab, ua rau nws yooj yim los rhuav tshem thaum ib qho txheej txheem embossing. Txhawm rau kom tsis txhob tawg thiab xyuas kom meej qhov kawg cov duab thiab qhov ntev ntawm cov khoom, feem ntau siv ob - cov txheej txheem tsim.

Kauj Ruam 1: Arc Forming. Raws li pom hauv daim duab (B), nco ntsoov cov ntsiab lus tseem ceeb hauv qab no:

A. Lub voj voog L1 nruab nrab ntawm cov ntsiab lus c thiab d tom qab arc tsim (qhov sib npaug ntawm peb qhov ntev arc) yuav tsum me ntsis ntau dua li qhov ncig L2 ntawm cov ntsiab lus a thiab b hauv qhov yuav tsum tau hla- ntu ntawm cov khoom (saib daim duab A rau a thiab b). Feem ntau, L1=L2 + (0.2 ~ 0.8) mm.

B. Qhov ncaj- kab nrug ntawm cov ntsiab lus c thiab d nyob rau hauv qis tuag insert yog sib npaug rau qhov ncaj- kab nrug D5 ntawm cov ntsiab lus a thiab b nyob rau hauv qhov yuav tsum tau hla- ntu ntawm cov khoom.

C. Thaum kaw cov pwm, xyuas kom meej tias qhov tsawg kawg ntawm qhov sib txawv ntawm lub arc nrog lub vojvoog r1 hauv daim duab thiab qhov qis tuag yog 60% ntawm cov khoom siv thickness (T * 60%).

Kauj ruam 2: Shaping. Muaj ob txoj hauv kev sib txawv. Raws li pom nyob rau hauv daim duab (C) thiab daim duab (D), txoj kev (C) feem ntau yog siv, thaum txoj kev (D) yog siv thaum cov duab xav tau ntawm lub convex hull tsis siab. Cov kauj ruam thiab txoj hauv kev los txiav txim siab qhov loj me thaum kos duab arc yog raws li hauv qab no: Txiav txim siab cov duab thiab qhov loj ntawm lub qhov sab hauv ntawm qhov qis tuag ntxig raws li qhov xav tau thiab qhov loj ntawm cov khoom. Saib daim duab (E). Nco tseg: a. Qhov ncaj- kab nrug ntawm cov ntsiab lus C thiab d yog sib npaug rau qhov ncaj- kab nrug D5 ntawm cov ntsiab lus a thiab b nyob rau hauv qhov yuav tsum tau hla- ntu ntawm cov khoom. b. Lub vojvoog r1 ntawm lub arc nyob rau hauv lub puab qhov ntawm qhov ntxig yog feem ntau ntawm 1 thiab 3 hli (inclusion), nrog rau 0.5 hli raws li ib tug increment. A. Kev txiav txim thawj zaug: r1 yog sib npaug rau lub vojvoog r ntawm qhov sib txuas ntawm cov khoom hla-section.

B. Ua ntej sab nraud qhov ntev ntawm cov khoom thaum tsim cov arc:

1. Raws li pom hauv daim duab (F), kos ib lub voj voog uas siv peb lub ntsiab lus (cov ntsiab lus tangent ntawm ob lub r1 arcs ntawm qhov qis tuag ntxig thiab qhov nruab nrab (g) hauv qab ntawm qhov convex).

2. Tom qab trimming raws li qhia nyob rau hauv daim duab (G), ntsuas tag nrho ntev L1 ntawm peb arc ntu ntawm cov ntsiab lus c thiab d.

3. Yog tias tag nrho qhov ntev L1 ntawm peb ntu ntu no tsawg dua qhov ncig L2 ntawm cov ntsiab lus a thiab b hauv qhov yuav tsum tau hla - ntu ntawm cov khoom, ces txav mus rau qhov nruab nrab g ntawm lub hauv qab ntawm qhov convex downwards los ntawm kev ncua deb h (h tuaj yeem nyob rau hauv increments ntawm 0.5 hli) kom tau qhov taw tes h, thiab redraw peb lub voj voog (los ntawm cov ntsiab lus h.

4. Rov ua ob kauj ruam saum toj no kom txog thaum L1=L2 + (0.2 ~ 0.8) mm txaus siab. Sab nraud qhov ntev ntawm cov khoom thaum tsim ib qho arc yog tau siv txoj kev no.

C. Txoj kev los txiav txim lub vojvoog ntawm lub kheej kheej ntawm qhov kawg ntawm arc - zoo li punch:

1. Sab nraud qhov ntev ntawm cov khoom thaum tsim cov arc yog txiav txim siab siv cov kauj ruam 3.3.2. Offset los ntawm ib cov khoom thickness. Raws li pom hauv daim duab (I)

2. Offset ob lub voj voog arcs nrog lub vojvoog r1 nyob rau hauv lub puab lub qhov ntawm qhov tuag insert los ntawm T * 0.6%. Raws li pom hauv daim duab (I)

3. Kos ib lub voj voog tangent rau peb lub arcs uas tau txiav txim hauv cov kauj ruam 3.3.3.1 thiab 3.3.3.2 siv txoj kev kos duab voj voog los ntawm peb lub ntsiab lus. Lub vojvoog R ntawm lub voj voog no yog lub vojvoog R ntawm tus kheej ntawm qhov kawg ntawm lub arc -zoo li punch (siv ib qhov chaw kaum, tab sis ua kom raug rau ob qhov chaw lej thaum qhov loj me). Raws li pom hauv daim duab (J)

D. Txiav txim siab daim duab... Diameter of the Arc-Shape Punch Body

1. Yog hais tias qhov nruab nrab ntawm tus kheej txiav txim siab nyob rau hauv (B) yog nyob rau saum npoo ntawm cov khoom siv (piv txwv li, qhov chaw sib cuag ntawm lub sab sauv ejector phaj thiab cov khoom), lub kheej kheej intersects nrog lub sab saum toj dav hlau ntawm cov khoom khoom, yog li tau txais tus ntoo khaub lig- seem ntawm lub arc- zoo li tus punch lub cev. Raws li pom nyob rau hauv daim duab (K), D9 yog lub cheeb ntawm lub arc -puab lub cev.

2. Yog hais tias qhov nruab nrab ntawm tus kheej txiav txim siab nyob rau hauv (B) yog nyob nruab nrab ntawm lub saum npoo (piv txwv li, qhov sib cuag ntawm lub sab sauv ejector phaj thiab cov khoom) thiab qis nto ntawm cov khoom, ces lub cheeb ntawm lub arc - zoo li tus punch lub cev yog npaum li cas... D9 sib npaug ntawm txoj kab uas hla ntawm tus kheej (ie, D9=2} * R), thiab qhov kawg punch yog ib tug nkhaus. Saib daim duab (I).

3. Yog tias qhov chaw nruab nrab ntawm qhov kev txiav txim siab nyob rau hauv (B) nyob rau hauv qab ntawm qhov chaw qis ntawm cov khoom siv (piv txwv li, qhov sib cuag ntawm qhov qis qis thiab cov khoom siv), tus thawj saib xyuas yuav tsum txiav txim siab.

E. Lwm yam kev ceev faj:

1. Tshawb xyuas seb cov punch nkhaus puas cuam tshuam nrog lub hauv qab tuag ntxig thaum lub sij hawm qhuav -firing (piv txwv li, thaum tsis muaj cov khoom nruab nrab ntawm lub Upper thiab qis tuag tab sis qhov tuag yog tag nrho);

2. Cov punch nkhaus yog mounted ntawm lub phaj clamping;

3. Txoj kev punch yog mounted ntawm lub stripper phaj.

Tsawg-profile forming method:

1. Profile radius (R): Generally, when H=6T, the punch radius (r)>=t, and the die radius (R)>=2T. Qhov tshwj xeeb R tus nqi raug kho raws li qhov profile qhov siab H.

2. Profile qhov siab: Tom qab tsim cov profile, kev ntxhov siab yog tsim los ntawm cov khoom ntws, ua rau cov khoom deformation. Yog li ntawd, rau loj - cheeb tsam profiles thiab cov khoom uas yuav tsum tau flatness siab, yuav tsum tau ib tug txheej txheem shaping tom qab tsim cov profile. Thawj kauj ruam ntawm kev tsim cov profile qhov siab yuav tsum yog li 0.2 hli siab tshaj qhov yuav tsum tau kos duab. Qhov thib ob kauj ruam ntawm shaping yog reshape rau tus nqi yuav tsum tau, saib daim duab (P).
3. Upper tuag: Txoj haujlwm tsim feem ntau yog ua raws li cov khoom zoo, raws li pom hauv daim duab (R). Rau qhov siab H<3T and no requirement for a slope, the upper die can be made into a straight punch as shown in Figure (Q). The size of the punch is taken as the side tangent to the product radius (r). As shown in Figure (O), please consult your superiors before adopting this method;

4. Tuag: Feem ntau, cov tuag tsis ua raws li cov duab, thiab cov phab ntsa tuag yog tangent rau cov khoom lub vojvoog (R); saib daim duab (O) rau kev tuag loj thiab kev tsim kho;

5. Sab saum toj thiab hauv qab: Feem ntau ua tsau, nrog ejector pins ntxiv rau sab nraum qhov tuag los nqa cov khoom; rau loj- cheeb tsam tsa pob, sab saum toj thiab hauv qab yog sib koom, thiab sab saum toj thiab hauv qab yog ua ntej-grooved thiab tsau nrog screws thaum txiav cov khoom;

6. For raised bumps with T>=1, cov kab siab tuaj yeem ntxiv nyob ib puag ncig lub pob kom txo qis deformation ntawm cov khoom los ntawm cov khoom ntws; saib daim duab (S); W=T, h=0.3t; Xav kawm hardware pwm tsim? Muaj teeb meem nrog automotive pwm tsim? Tsis paub yuav kawm li cas? Tsis muaj teeb meem! Tsuas yog teb "cov zej zog" hauv cov lus hauv qab no, thiab koj yuav pom cov ntaub ntawv qhia thiab nkag mus rau cov peev txheej kawm PPT.
