Panon ya Makagawa na Kwalipikadon Produkto so Stamping Die?
Dakel a totoo so natatakot ed panagdrowing na saray die. Saya so lapud aliwa labat ya dakel a bengatla so kaukolan ya ikonsidera legan na panagdesinyo, noagta mas importante, mabetbet ya ag da naabot so labay dan resulta legan na die trials, kanian kaukolan so dakel a rebisyon. Kanian, say pakatipon na eksperiensya panamegley na panagpraktis et makagunggona ed panagdrowing na desinyo na die.
Saray onggendan ya anemiran punto so insumaryo na saray inhinyero mi:
1. Saray materyales
Saray maong a materyales so kapaldua na laban. No nipaakar ed panagdrowing, ag nayarin ibaliwala so kaimportantian na saray materyales.
Saray manunan cold-rolled thin steel sheets ya uusaren ed panagdrowing et kaiba so 08Al, 08, 08F, 10, 15, tan 20 steels. 08 steel so sankalaknaban ya uusaren, tan naapag ed rimmed steel tan killed steel. Say rimmed steel et abeban presyo tan maong so kalidad na tapew to, balet ta walaan met na grabe ya inkaapag-apag tan tendensian ontatakken, kanian ag-itan matukoy parad saray parte ya mankaukolan na atagey a stamping performance tan istrikton kakaukolanen ed itsura. Say killed steel et walaan na superyor ya performance, ya parepareho so kalidad to, balet mas mabmabli. Say representative grade et aluminum-killed steel 08Al. Saray dayo ya asero et angusar na SPCC-SD deep-drawing steel, ya mas maong so tensile properties to nen say 08Al. 1. No aliwan malet so pankaukolan na kustomer tan ag-itan nasumpal na paulit-ulit ya mold trials, salien so sananey a materyales.
2. Panamta na Sukat na Blangko
Parad saray simplin manpapawil-pawil a parte, say diametro na blangko et manguuman legan na proseso na ag--panpaitneng, balet say kapal na materyal et mansiansian asingger ed orihinal a kapal. Nayarin kalkulaen iya base ed prinsipyo ya say blangko ya lugar et mipara ed area na indrowing ya parte (iyarum so trimming allowance no kaukolan so trimming). Balet, saray ginuhit a parte et mabetbet a walaan na komplikadon kurti tan proseso, tan no maminsan et kaukolan so pangipaitneng. Bangta dakel so 3D software programs ya nayarin usaren parad panag-unfolding na kalkulasyon, say inkasusto ra et aglawas makaabot ed nakaukolan ya inkasusto.
Panon ya naresolbe so problema na ag-inkayadyari na produkto? Solusyon: Subok so materyales.
A. Say sakey a produkto et ondalan ed dakel a kundang, say unonan kundang et kaslakan ya panag-blank. Unona, manggawa na unfolding calculations pian natalosan so kurti tan kabaleg na blangko, ya ontulong pian naamtaan so kabaleg na blanking die. Agmo umanen so laki tan bibiin die na blanking die kayari na desinyo na molde. Unona, usaren so wire EDM pian makinaen so blangko (saray angkakabaleg a blangko et nayarin gilingan insan punasen panamegley na clamp). Kayari na paulit-ulit ya eksperimento ed ontumbok ya proseso na panagdrowing, say sukat na blangko et nadetermina la, insan say laki tan bii ya die parad proseso na panag-blank et na-machine.
B. Ibaliktad so proseso: suboken nin unona so drawing die, insan i-machine so sukat na gilig na blangko, ya naabot so doble ed resulta diad kapaldua na sagpot.
3: Stretch Factor(m)
Say stretch factor m et sakey ed saray manunan parameter na proseso ed kalkulasyon na proseso na panagdrowing. Kaslakan ya uusaren iya pian naamtaan so inkauksoy tan bilang na saray panag-unat. Dakel a bengatla so mangiimpluensya ed stretch factor m, kaiba lay saray kablian na materyal, say relatibon kapal na materyal, paraan na panag-unat (salanti, say kiwawala odino kiwawala na blangko a panangiyan), bilang na panag-unat, kapeles na panag-unat, radius na suyok na laki tan bii, tan say lubrication.
Say kalkulasyon tan prinsipyo na panagpili parad stretch factor m et manunan topic ya nabasa ed nanduruman stamping manuals, tan wala ray nanduruman paraan, kaiba lay deduction, table lookup, tan kalkulasyon.
A. Say relatibon kapal na materyal, paraan na panag-unat (salanti, say kiwawala o anggapo na blangko ya panangiyan), tan say bilang na panag-unat et mairap ya i-adjust legan na panag-apiger na die; manalwar ka!
B. Mangiyan na lubricant ed die, odino manbalot na film bag ed sheet.
C. No walay tensile cracking, mangiyan na lubricant ed die (aliwan say punch). Sakbongan so workpiece na 0.013-0.018mm ya kapal na plastic film diad gilig na die.
4. Panangipainit ed Gawaen
Legan na proseso na panag-inat, say workpiece et ondalan ed cold plastic deformation, ya manresulta ed cold work hardening. Saya so mamapaabeba ed inka-plastiko to, mamaaligwas ed resistensya to ed deformation, tan mamaaligwas ed inka-malet to. Niarum ni, no say desinyo na mold et agmanepeg, nayarin kaukolan so intermediate annealing pian onlemew so metal tan ompawil so inkaplastik to.
Tandaan: Diad inkalapagan iran proseso, ag nakaukolan so intermediate annealing, ta mamaatagey so gastos. Manpili ed baetan na pangiyarum na kaaruman iran kundang odino pangi-annealing. Usaren ya maalwar!
Say annealing et kaslakan ya gagawaen ed abeban temperatura, ya tatawagen met ya recrystallization annealing.
Walay duaran manunan ikonsidera legan na panag-annealing: decarburization tan oxidation. Dia, manpokus tayo ed oxidation. Say oxidation et mamawala na sukat ed workpiece, ya walaan na duaran makaderal ya epekto: babawasan toy epektibon kapal na workpiece tan lalon ondarakel so mold wear.
No limitado so kondisyon na kompanya, kaslakan ya uusaren so conventional annealing. Pian nabawasan so pakaporma na scale, say hurnoan et nepeg ya panoen anggad posible legan na panag-annealing. Angusar ak met na pigaran aliwan kaslakan a paraan:
A. No daiset so workpieces, nayarin ilaok iratan ed arum ya workpieces (no ipasen ya pareho so proseso na annealing).
B. Iyan iray workpieces ed sakey a kahon ya bakal, selyaan iratan na welds, insan ikarga iratan ed hurnoan. Pian naekal so ulpo, nepeg ya gawaen so panag-atsara kayari na panag-anneal, no manepeg.
No magenap la ray kondisyon na kompanya, nayarin usaren so nitrogen furnace annealing, ya tatawagen met ya bright annealing. No ag-imanoen a maong, say kolor to et ngalngalin pareho ed samay antis ya in-anneal.
5. Parad saray metal ya mabiskeg so cold work hardening odino no walay nagagawan man-crack legan na test molds tan anggapoy arum ya solusyon, nayarin idagdag so intermediate annealing step.
6. Kaunoran, pigaran kaaruman a punto:
A. Saray sukat ed saray drowing na produkto et nepeg ya markaan ed sakey a diking no posible pian malinew ya nipanengneng no kasin say tutukoyen da et saray sukat ed paway odino diad loob. Agmo markaan so loob tan paway a sukat. No wala ray isyu ed saray drowing ya inter na arum, mitongtong ed sikara. No posible so inkaparaan, nepeg ya nadampot itan. No andi, nepeg ya talosan so siglaotan na pankakasakey na workpiece ed arum nin kabiangan.
B. Parad unor a proseso, no say sukat na workpiece et walad paway, say die so manunan sengegan, tan say clearance et nadampot diad pambawas ed sukat na punch. No say sukat na workpiece et walad loob, say die so manunan sengegan, tan say clearance et nadampot diad pamarakep ed sukat na die.
C. No mandedesinyo na corner radii na punch tan die, usaren so sankamelagan ya naabuloyan ya balor pian napagaan so ontumbok ya pangapiger ed die.
D. No amtaen so sengegan na panbitak na workpiece, ikonsidera iray onggendan:
Saray bitak ya sengegan na makapuy a kalidad na materyal et mabetbet ya mapitek odino ag-regular so kurti to, bangbalet saray bitak ya sengegan na proseso odino molde et kaslakan ya mas parepareho.
E. "Mas dakel so mangitonton ed kulubot, mas daiset so mangitonton ed bitak." Base ed sayan prinsipyo, say kondisyon na iyaagus na materyales et nayarin i-adjust diad pangi-adjust ed pressure na blank holder, pamarakep ed saray draw ribs, pangi-adjust ed corner radii na punch tan die, tan pangi-cut na proseso na notch ed workpiece.
F. Pian naseguro so ag-onkapuy tan ag-onkupas, say punch tan die, ontan met ed blankon holder, et nepeg ya erepen tan, no nakaukolan, et malet ya chrome plated.
No interesado kayo ed amag, ag kayo mapaga ya mitongtong ed sikami!
