200529947 九、發明說明： I：發明戶斤屬之技術領诚3 發明領域 本發明係有關於用於金屬板或相似物之切削（cutting) 5 加工或搪孔(boring)加工的衝壓加工用模具，更特定言之， 本發明係有關於製造空氣調節器或相似裝置之熱交換器所 用的散熱片（fin)的衝壓加工用模具，以及使用該模具的衝 壓加工方法。 L· Ji 10 發明背景 傳統上，如第11A圖中所示，汽車用空氣調節器以及室 内空氣調節器或相似裝置之熱交換器所用的散熱片，係藉 由衝壓加工所製造。此衝壓加工主要係由以下步驟所組 成：一預成型(preforming)步驟用以使諸如鋁板或相似物的 15金屬板易於加工；一穿孔(piercing)及擴孔(burring)步驟用於 鑽孔及將預成型金屬板擴孔；一熨平(ironing)步驟用於自金 屬板上孔之外周圍的一突出部分構成一軸環(c〇llar);以及 一再呈喇17八形展開(reflaring)步驟用於將所構成軸環之一前 端部部分彎曲。藉由對諸如鋁板或相似物的金屬板施以該 20衝壓加工，製成如第iiB圖中所示之板極散熱片（plate fin)。 根據該一衝壓加工，為了改良加工能力，模具及金屬 板之潤滑係為重要的。於衝壓加工中，有關於潤滑的先前 技術，例如，係揭露在^-^12227及ΐΡ-υΜ·Α·6Μ〇2323 中，並將於之後說明該等先前技術。 200529947 目前，就於製造熱交換器或相似裝置所用的散熱片的 衝壓加工中之潤滑而言，係使用碳氫化合物為基體的潤滑 油。碳氫化合物為基體的潤滑油已廣泛地使用作為一潤滑 液體，使與全球環境和諧共存，因為與那時以前所使用的 5 礦物油為基體的潤滑油所不同的是，碳氫化合物為基體的 潤滑油不需藉由一有機氯溶劑加以淨化。 就藉使用碳氫化合物為基體的潤滑油執行衝壓加工而 言，鑑於散熱片之製造效率，在加工之後加熱該黏附至散 熱片之潤滑油，將潤滑油蒸發及乾燥。因而，為了防止將 10 蒸發的碳氫化合物為基體的潤滑油排放至大氣中，所以必 需藉由觸媒燃燒進行處理。此外，相關於衝壓加工中所用 之碳氫化合物為基體的潤滑油並係可回收為液體，當工業 排放時需要規定的分離裝置(disinstallation)。就該一情況而 言，當使用碳氫化合物為基體的潤滑油時，當工業排放或 15 相似狀況時諸如觸媒燃燒及分離裝置的後處理係極為昂 貴。此外，因應近年來全球環境保護的普及，需要與全球 環境更為和諧的潤滑液體。 近年來，已發展一種技術用於使用水或是水為基體的 潤滑液體，其係於水中溶解的一水溶性潤滑劑用於諸如切 20 削或是相似加工的金屬處理，取代碳氫化合物為基體的潤 滑油。假若在衝壓加工中以水及水為基體的潤滑液體作為 潤滑，則可減少當工業排放時的觸媒燃燒及分離裝置，並 且達成產物與自然環境和諧共存。此外，可減少在使用潤 滑液體之後的後處理，因此能夠將製造裝置及生產線微型 200529947 化，並極其地降低成本。然而’水及水為基體的潤滑液體 的問題在於其之潤滑能力較碳氫化合物為基體的潤滑油遜 色。 另一方面，根據近年來熱交換器或相似裝置之散熱片 5之製造工業，為了改良潤滑能力，使用經潤滑劑塗佈的鋁 板作為散熱片之加工材料，其中該一潤滑劑塗層主要係以 乙二醇所構成，將其塗佈在鋁板之表面上，厚度約為〇1公 厘。根據在本發明製作之前已完成的先期研究，所得詰論 為：在衝壓加工步驟中，就使用該經潤滑劑塗佈的鋁板而 10言，相關於藉由水及水為基體的潤滑液體，除了穿孔步驟 外，於該預成型步驟、擴孔步驟、熨平步驟、以及再呈喇 八狀展開步驟中皆無問題。 然而，於穿孔步驟中，即使使用經潤滑劑塗佈的鋁板， 泫於剪力面處暴露的一鋁部分以及模具係直接地相互接 15觸。因此，如此造成之問題在於，重複該等步驟，由於摩 擦或相似動作所產生的熱量造成公模及母模發熱，因此模 具受到損害(參考第13圖）。 此外’根據本發明之發明者的先期研究，亦發現經潤 /月劑塗佈的I呂板之潤滑劑塗層係由諸如乙二醇或相似物的 20 一水溶性材料所製成，因此假若水或包含大量的水為基體 的潤滑液體，相關於作為一加工主體的一平板所使用量為 大時，則潤滑劑塗層被沖掉以致損及潤滑能力並使接續步 驟受到影響。因此，在穿孔時對需要潤滑液體的一部分局 部地供給潤滑液體，似乎係為有效的。 200529947 就局部地供給潤滑液體的技術而言，上述說明的 JP-A-7-112227揭露一種模具裝置，能夠局部地將衝壓加工 用油供給至於熨平步驟中所用的衝頭的一前端部部分，以 及完成衝壓加工的材料之一部分。此外，上述說明的 5 JP-UM-A-61-102323揭露一穿孔衝頭，能夠局部地供給潤滑 油至可滑動地與係為一加工主體的材料的一剪力面接觸的 穿孔衝頭的一前端部部分的一外周圍。 此外，傳統地，於熱交換器用之散熱片的衝壓加工場 合所使用的穿孔衝頭，係與碳氫化合物為基體的潤滑油一 10同使用，與在前述說明的JP-A-7-112227揭露的一擠製構件 (頂出具(knock out))相同，在穿孔衝頭中配置一潤滑油路 徑，因此能夠局部地將潤滑油供給至穿孔衝頭的前端部部 分的外周圍。如第12圖中所示，該一傳統式穿孔衝頭係與 作為母模的擴孔衝頭一同作業。 15 由第12圖中明顯可見，一穿孔衝頭101係配置一潤滑油 路控133，於内部係於一軸方向上由一底座部分117貫穿至 其之一前端部部分，以及_於徑向上開啟至穿孔衝頭ι〇ι之 一外周圍表面113的潤滑油喷射孔135，係構成在底座部分 U7之一下部分，不致與一擴孔衝頭102的一接受孔128之内 20 表面干擾(不配合）。 根據該—結構，將潤滑油局部地供給至穿孔衝頭101 之月）鳊°卩"卩分及外周圍表面113。此時，擴孔衝頭102具有 一傳統形狀，其之接受孔128與該穿孔衝頭1〇1配合。 然而，配置該傳統式潤滑油路徑的模具以及潤滑油噴 200529947 射孔於實際使用上並不足夠，當與水及水為基體的潤滑液 體一起使用時，由於藉使用此傳統模具假使相關於經潤滑 劑塗佈之鋁板完成穿孔同時以水為基體的潤滑液體潤滑， 則牙孔衝頭101及擴孔衝頭102之前端部部分，由於缺乏潤 5 滑(不足）而發熱，因此造成該擴孔衝頭102斷裂。 實際上，藉使用該一傳統式模具，在每分鐘2〇〇至21〇 擊（次）的速率下完成經潤滑劑塗佈之鋁板的穿孔加工，約經 九萬二仟擊將使模具受到損害。於第13圖中所示，該一掃 描式電子顯微鏡(SEM)相片顯示此受損的傳統式模具的狀 10况。相關於第13A圖，所發現的是該穿孔衝頭101及擴孔衝 頭102係為發熱的，該擴孔衝頭1〇2其之前端部部分斷裂， 以及該斷裂件係固定至穿孔衝頭之外周圍表面。第13B圖係 為藉由於第13ASI巾所示的-方塊所環繞的—部分的一放 大相片，並由此圖式，發現穿孔衝頭1〇1之前端部部分的一 15周圍邊緣，因摩擦或相似原因而具有一極為粗糙的表面。 C發明内容3 發明概要 本發明已將前述問題加以考量，以及本發明之一目的 在於提供衝壓加工用模具，其能防止即使當使用水及水為 基體的潤滑液體潤滑時因摩擦而造成模具發熱，並足供實 際所用以及一衝壓加工方法。 為達到上述目的，於本發明之衝壓加工用模具中，當 公模與母模相互配合用以切削材料時，作為一潤滑液體池 其中至少暫時地储存潤滑液體的一主要結構，係完全或部 200529947 分地構成在彼此部分重疊的公模之一部分重疊部分的一外 周圍表面上或是母模的一部分重疊部分的一内周圍表面 上。 根據該一結構，至少暫時地能夠在一配置在公模之外 5 周圍表面或是母模之内周圍表面上的潤滑液體池中儲存潤 滑液體。假若將潤滑液體儲存在該潤滑液體池中，則該儲 存的潤滑液體係充分地供給至特別需要潤滑的一部分，例 如，介於公模與母模之間以及介於公模與金屬板之間，因 此在該一部分的摩擦阻力係為減少的。此外，因為所有或 10 是一部分的潤滑液體池係構成在公模及母模彼此部分重疊 的該等部分重豐處，所以能夠有效地潤滑及冷卻係為摩擦 熱產生部分的公模及母模之二部分重疊部分。 此外，根據本發明，一凹入部分係構成在公模之部分 重疊部分的外周圍表面或是母模之部分重疊部分的内周圍 15 表面的至少一部分上作為潤滑液體池。 根據該一結構，將公模與母模相互滑動地接觸的一區 域製得較小，因此由於模具之摩擦表面減小而能夠防止摩 擦熱產生。特別地，當潤滑液體池之至少一部分係構成在 公模與母模彼此部分重疊的該等部分重疊部分之外周圍表 20 面處時，將模具與金屬板(欲加工之材料)相互滑動地接觸的 區域製得較小，因此能夠進一步地防止產生摩擦熱。此外， 假若係使用水為基體的潤滑液體作為潤滑液體，則由於水 為基體的潤滑液體的比熱係為高的，所以能夠有效地將模 具冷卻。 200529947 此外，根據本發明，外徑小於公模之前端部之外徑的 一小直徑部分，係構成在公模之部分重疊部分之外周圍表 面上作為前述的潤滑液體池，可交替地，内徑大於母模之 開口端邊緣之内徑的一大直徑部分，係構成在母模之部分 5 重疊部分之内周圍表面上作為前述的潤滑液體池。 根據該一結構，小直徑部分或大直徑部分能夠在製造 模具時藉由切削加工而製成，並且藉由簡單的加工，能夠 在模具中提供具高潤滑能力及高冷卻效果的潤滑液體池。 此外，根據本發明，用於供給潤滑液體至潤滑液體池 10 的一潤滑液體路徑，係配置在公模或是母模中。 根據該一結構，潤滑液體流經該潤滑液體路徑，並能 夠確實且有效地將潤滑液體供給至潤滑液體池。假若係自 底座部分至公模之内部構成該潤滑液體路徑，俾便與構成 在公模之部分重疊部分之外周圍表面處的潤滑液體池連 15 通，潤滑液體池中的潤滑液體流經公模之内部，因此能夠 更為能夠確實且有效地將潤滑液體供給至位在公模之部分 重疊部分之外周圍表面處的潤滑液體池。 因此，根據本發明，潤滑液體路徑包括一軸向路徑， 其係沿著一軸方向自公模之底座部分而構成，以及一分支 20 路徑係與該軸向路徑連通並係在包括公模之一徑向組件的 一方向上伸長；以及用以將潤滑液體之流向自公模之軸向 改向為包括徑向組件之方向的一分歧壁，係配置在軸向路 徑與分支路徑十字交叉的一交叉部分中。 根據該一結構，流經軸向路徑的潤滑液體係與一分歧 200529947 壁衝突，因而流至一分支路徑。因此，進一步更為確實且 有效地將潤滑液體供給至位在公模之部分重疊部分之外周 圍表面處的潤滑液體池。 此外，根據本發明，潤滑液體池之一周圍邊緣的至少 5 一部分係為去角的。 根據此結構，該潤滑液體自潤滑液體池向下地朝向作 為與諸如銘板的金屬板接觸的—部分，具有最大的負荷並 需最多的潤滑的模具之前端部部分及開口端部部分流動， 並且如此使潤滑液體易於供給至模具之前端部部分及開口 1〇端部部分。因此’進-步改良與模具有關的潤滑能力及冷 卻能力，因此能夠防止模具發熱。 再者，根據本發明，所構成之該潤滑液體池复中介於 潤滑液體池與公模之前端部部分或是母模之開口端部邊緣 的一段距離係部分地製得較短。 15 20 根據此結構，該潤滑液體池部分地接近具最大負荷之 模具的前端部部分及開口端部部分，因此於該等^户， 潤滑液體池巾_驗體輕易地流至公模之前端部部^及 母模之開口端部部分。另一太；.χ 1刀力方面，在公模之前端部部分及 母模之開Π端部部分以外位置處，能夠確保將諸如銘板的 金屬板切削及穿孔所需㈣度。因此，能财效地潤滑公 板之前端部部分及母模之開口端部部分，同時維持模具加 工所需之強度。 此寺饭右使用水或是具有於水巾溶解的水溶性潤滑 劑的水為基體之潤滑液體作L㈣，_夠實現生產 12 200529947 與自然環境和諧共存的理想，能夠降低製造成本，加工裝 置及加工生產線能夠簡單且微型化。 再者，當藉由使用上述衝壓加工用模具在一薄金屬板 上多次連續地構成孔時，本發明之衝壓加工方法可包括一 5供給潤滑液體至該潤滑液體池的步驟，在由公模與母模相 互配合的-狀態至其於第二位置相互配合的一狀態的該一 段期間，當公模與母模相互配合其中至少暫時地儲存潤滑 液體時，該潤滑液體池係完全或部分地構成在彼此部分重 疊的公模之部分重疊部分的外周圍表面上或是母模的部分 10 重疊部分的内周圍表面上。 因此，能夠針對每-衝壓循環將潤滑液體供給至潤滑 液體池，並且針對每一衝壓循環至少暫時地將潤滑液體儲 存在該潤滑液體池中，因此改良了當公模與母模相互配合 時’該公模與母模彼此部分重疊的該等部分重疊部分處的 15 潤滑及冷卻效率。 根據本發明之衝壓加工用模具，藉由在公模或母模中 構成潤滑液體池，將潤滑液體供給至需要充分潤滑的模且 之前端部部分，並且如此能夠改良潤滑效果。再者，藉由 配置潤滑液體池，能夠使模具之摩擦部分之面積較小。從 20而，即使當於衝壓加工中使用水及水為基體的潤滑液體戍 相似物時’亦能夠防止因模具之摩擦而發熱，以及即使當 於衝壓加工中使用水及水為基體的潤滑液體或相似物取代 衝壓加工油時，亦能夠提供足以供實際使用的衝壓加工用 模具。 13 200529947 此外，根據本發明之衝壓加工方法，由於使用上述模 具並且當潤滑液體儲存在該 >間滑液體池中時公模與母模彼 此配合，所以改良了該公模與母模彼此部分重疊的該等部 分重疊部分處的潤滑及冷卻效率。因此，即使當使用低潤 5 滑能力的水為基體的潤滑劑時’亦能防止因摩擦所造成的 諸如模具發熱或相似狀況的缺點，俾便提供足以供實際使 用的衝壓加工方法。 此時，根據本發明之衝壓加工用模具，即使當使用與 碳氫化合物為基體的潤滑油相較具低潤滑能力的水為基體 馨 10 的潤滑液體時，亦能夠預期當使用傳統的碳氫化合物為基 體的潤滑油時能夠延長模具之使用壽命。 圖式簡單說明 第1A至C圖係為本發明之一第一具體實施例的穿孔及

弟1A圖係為本發明之衝壓加工用的一第一具體實施例 的一部分放大的縱向斷面圖，該模具應用於穿孔及擴孔。 於第1A至C圖中所示的模具中，分別地使用作為一公模的 5 一牙孔衝頭1用於在一金屬板中穿孔用以使該孔明顯，以及 作為一母模的一擴孔衝頭2。穿孔衝頭丨及擴孔衝頭2係分別 以燒結碳化物製成。該穿孔衝頭i係構形為一上模5連同一 擴孔用圓衝頭(diebutt〇n)3，其係配置俾便環繞該穿孔衝頭 1，以及該擴孔衝頭2係構形為一下模6連同一脫料板 1〇 (stripper plate)4，其係配置環繞該擴孔衝頭2。 該穿孔衝頭1及擴孔衝頭2在配置於其間的金屬板上， 藉由剪力構成一孔，並在構成該孔之後，將穿孔衝頭丨配裝 在擴孔衝頭2中，因此該穿孔衝頭丨及擴孔衝頭2相互配合。 潤滑液體池10係配置在穿孔衝頭1之一外周圍表面13 15上。根據本具體實施例，就該潤滑液體池10而言，構成一 小直徑部分其之直徑小於穿孔衝頭1之一前端部部分15處 的一外徑。第1B圖係為部分重疊部分i3a及24a的一範圍的 一放大視圖，其中當穿孔衝頭丨及擴孔衝頭2相互配合時， 穿孔衝頭1之外周圍表面及擴孔衝頭2之内周圍表面彼此部 20分重疊。如第1B圖中所示，穿孔衝頭i之潤滑液體池1〇係配 置在穿孔衝頭1之部分重疊部分13a的外周圍表面上。根據 本具體實施例，構形為潤滑液體池1〇的小直徑部分，係配 置在一位置其係與穿孔衝頭1之一前端部邊緣15a分開一段 長度’為了確保於穿孔作業在其上承受一相對大負荷的穿 16 200529947 孔衝頭1之1^部部分I5處的足夠強度。 π穿孔衝頭1具有一與潤滑液體池10連通的潤滑液體路 徑31。如圖式中所示’所構成的該潤滑液體路徑31係由穿 ，衝社—底座部分17至穿孔衝頭之内部，用以與構成在 部分重S部分13a❸卜關表面上的騎液體⑽連通。本 具體貫施例之潤滑液體路徑31係藉由沿著—軸方 構!的一轴向路徑33，以及-與此轴向路独 所=係/σ考牙孔衝頭1之一半徑方向伸長的分支路徑35 10 15 20 此時’本具體實施例並不 液體路徑31可藉由構以彳^、、纟。構，以及潤滑 精由構成在作為公模的穿孔衝則上 路徑33構成，以及分支路徑(未顯示)其係自—縱向部分中一 壬倒m的軸向路經33所構成，並係在包括—半徑方向的一 方向上伸長’俾便與潤騎體池10連通。 根據本具體實施例，潤滑液體路徑31係配置在作為八 模的穿孔觸1之㈣。“，假若潤滑賴Μ供給至^ 潤滑液體池10，m㈣路徑31可配置在純及母模的 任-者中。此外，騎㈣路徑31可配置在模具之内部或 是模具之外部。再者，根據本具體實施例，二分支路㈣ 係配置在半㈣向上’然而，假若能夠充分地確保在前端 部部分15處㈣度，射提供適當數目之分支路徑％，例 如，四或六分支路徑。 由第1A圖中明顯可見，於本《實施例之分支路徑35 中’其之-部分係於構形該潤滑液體池1〇的較小直徑部分 17 200529947 處開啟，以及其之另-部分係在與穿孔衝頭！之一前端部邊 緣15a接近的一位置處，在穿孔衝頭之外周圍表面上開啟。 因此，使分支路徑35之一開口部分35a成為潤滑液體池1〇的 一部分，因此，在分支路徑35之開口部分35a處介於潤滑液 5體池10與穿孔衝頭1之前端部邊緣15a之間的一段距離係部 分地為短的，以該一方式構成該潤滑液體池1〇。 此時，當在母模中提供潤滑液體池1〇時，能夠構成潤 滑液體池ίο因此介於潤滑液體池10與母模之端部邊緣26a 之間的距離係部分地製成短的。 10 此外，为歧壁37係配置在穿孔衝頭1之内部該軸向路 徑33與分支路徑35交又的一部分處（分支路徑35自軸向路 徑33分支的分支部分）。此時，根據本具體實施例，藉由使 位在牙孔衝頭1之前端部側的軸向路徑33較與分支路徑％ 之交叉部分為窄而構成分歧壁37，然而，所構成的分歧壁 15 37以致該軸向路徑33於分歧壁37處終止。 於此，相關於第1C圖，說明作為參考的穿孔衝頭j之該 等尺寸的一實例。於此實例中，穿孔衝頭丨之前端部部分之 一直徑d係為4·8公厘，以及於一轴向上自前端部邊緣至小 直徑部分的一段長度係為2公厘。於作為潤滑液體池1〇的小 20直徑部分中，該軸向長度h係為3.5公厘，該一自部分重疊 部分之外周圍表面的一凹處的深度係為〇·2公厘（第lc圖中 的f) ’以及此凹處之一直徑（外徑)s係為4.4公厘。因此，於 此例中，潤滑液體池1〇之容積係約為10.llmm3，並能夠在 潤滑液體池10中根據此容積儲存潤滑液體。此外，相關於 18 200529947 潤滑液體路徑31中軸向路徑33之直徑，由底座部分17至分 歧壁37之直從係為1=2公厘，以及由分歧壁π至穿孔衝頭1 之前端部部分的直徑係為e=l公厘。再者，分支路徑35之直 · 徑j係為1.5公厘。 5 作為母模的擴孔衝頭2係為開啟的，其之内徑係稍大於 穿孔衝頭1之前端部部分15的外徑，並具有一接受孔28用以 接受穿孔衝頭1之前端部部分。接受孔28之一内周圍表面24 具有一部分重疊部分24a之内周圍表面，其當穿孔衝頭1與 擴孔衝頭2相配合時，與穿孔衝頭丨之部分重疊部分丨％的外 鲁 ίο周圍表面部分重疊且滑動地接觸。此外，二階梯部分44及 45係自接文孔28之部分重疊部分24a之内周圍表面向下地 配置，因此向下地内徑係較大並且當藉由穿孔衝頭i在金屬 板上構成一孔時所產生的一金屬元件，係易於自擴孔衝頭2 落下。 15 其次，將說明於第1A至1c圖所示之穿孔及擴孔用模具 裝置的作業。於此例中，根據本具體實施例，第1圖中的一 下方向係為插入穿孔衝頭！的一方向，以及一上方向係為將 # 穿孔衝頭1拉出的一方向。 作為熱輻射散熱片之一材料的諸如經潤滑劑塗佈的鋁 · 2〇板或相似物的金屬板，係安裝在脫料板4上，之後，上模5 , 洛下。穿孔衝頭1之前端部邊緣15a與金屬板接觸，之後， 該金屬板係置於圓衝頭3與脫料板4之間。該穿孔衝頭丨進一 步洛下，並且當穿孔衝頭丨之前端部部分15係與擴孔衝頭2 之接文孔28相配合時，該金屬板受剪力切削用以構成一孔。 19 200529947 在構成一孔之後，當穿孔衝頭1向上移動時，該擴孔衝 頭2亦向上移動。由於此向上移動，金屬板之構成孔的周圍 邊緣係藉由配置在擴孔衝頭2之一前端部部分％處的一上 推部分42向上推，並藉由該上推部分42與圓衝頭3之一擴孔 5接爻部分46完成擴孔作業。之後，上模5向上移動，擴孔衝 頭2向下移動，藉由脫料板4將穿孔及擴孔加工金屬板自擴 孔衝頭2去除，因而結束該穿孔及擴孔步驟。 接著，相關於第2及3圖，以下將說明穿孔時該潤滑液 體/也10之影響。第2圖所示係為於第1圖中該衝壓加工用模 1〇具中穿孔衝頭1與擴孔衝頭2相配合的狀態、，以及第3圖中所

Description of the invention: I: The technical leader of the inventor 3 Field of the invention The present invention relates to a stamping die used for cutting 5 metal plates or the like 5 processing or boring processing More specifically, the present invention relates to a stamping processing die for manufacturing a fin for a heat exchanger of an air conditioner or the like, and a stamping processing method using the same. L. Ji 10 Background of the Invention Traditionally, as shown in Fig. 11A, the heat sinks for air conditioners for automobiles and heat exchangers for indoor air conditioners or similar devices are manufactured by stamping. This stamping process is mainly composed of the following steps: a preforming step to facilitate the processing of 15 metal plates such as aluminum plates or the like; a piercing and burring steps for drilling and Reaming the preformed metal plate; an ironing step for forming a collar from a protruding part around the hole on the metal plate; and a step of reflaring repeatedly It is used to bend one of the front end portions of the formed collar. By subjecting the metal plate such as an aluminum plate or the like to the 20 stamping process, a plate fin as shown in Fig. IiB is produced. According to this press working, in order to improve the processing ability, the lubrication of the mold and the metal plate is important. In the stamping process, there are previous technologies related to lubrication, for example, they are disclosed in ^-^ 12227 and ΐΡ-υΜ · Α · 6Ｍ〇2323, and these prior technologies will be described later. 200529947 At present, for the lubrication of the stamping process of the heat sink or the like used in the manufacture of heat sinks, hydrocarbon based lubricants are used. Hydrocarbon-based lubricating oils have been widely used as a lubricating liquid to coexist in harmony with the global environment, because unlike the 5 mineral oil-based lubricating oils used before then, hydrocarbons are used as a base. The lubricating oil does not need to be purified by an organic chlorine solvent. In the case of performing a stamping process by using a hydrocarbon-based lubricant, in view of the manufacturing efficiency of the heat sink, the lubricant adhered to the heat sink is heated after processing to evaporate and dry the lubricant. Therefore, in order to prevent the evaporated hydrocarbon-based lubricating oil from being discharged into the atmosphere, it must be treated by catalytic combustion. In addition, the hydrocarbon-based lubricating oil used in the stamping process is recoverable as a liquid, and a prescribed separation installation is required when industrial discharge is performed. In this case, when a hydrocarbon-based lubricant is used, after-treatment such as catalytic combustion and separation devices is extremely expensive when industrial emissions or similar conditions are used. In addition, in response to the spread of global environmental protection in recent years, lubricating liquids that are more harmonious with the global environment are required. In recent years, a technology has been developed for the use of water or water-based lubricating liquids. A water-soluble lubricant dissolved in water is used for metal processing such as cutting or similar processing, instead of hydrocarbons. Base oil. If the water and water-based lubricating liquid is used as lubrication in the stamping process, the catalyst combustion and separation device during industrial discharge can be reduced, and the product and the natural environment coexist in harmony. In addition, since the post-treatment after using the lubricating liquid can be reduced, the manufacturing apparatus and the production line can be miniaturized, and the cost can be extremely reduced. However, the problem of 'water and water-based lubricating liquids is that their lubricating ability is inferior to that of hydrocarbon-based lubricating oils. On the other hand, according to the manufacturing industry of the heat sink 5 of a heat exchanger or similar device in recent years, in order to improve the lubricating ability, an aluminum plate coated with a lubricant is used as a processing material of the heat sink, in which the lubricant coating is mainly It is composed of ethylene glycol and is coated on the surface of an aluminum plate to a thickness of about 0.1 mm. According to the preliminary research that has been completed before the production of the present invention, it is concluded that: in the stamping process step, the aluminum plate coated with the lubricant is used, and 10 words are related to the lubricating liquid with water and water as the base. Except for the perforation step, there are no problems in the pre-forming step, the reaming step, the ironing step, and the re-opening step. However, in the perforating step, even if a lubricant-coated aluminum plate is used, an aluminum portion exposed on the shear surface and the mold are directly in contact with each other. Therefore, the problem is that if the steps are repeated, the mold and the mold become hot due to the heat generated by friction or similar actions (refer to Figure 13). In addition, according to a preliminary study by the inventor of the present invention, it was also found that the lubricant coating of the lubricating plate coated by the lubricating / moisturizing agent was made of a 20-water-soluble material such as ethylene glycol or the like, so If water or a lubricating liquid containing a large amount of water as a substrate is used in a large amount in relation to a flat plate as a processing body, the lubricant coating is washed away to damage the lubricating ability and affect the subsequent steps. Therefore, it seems effective to supply a part of the lubricating liquid to the lubricating liquid at the time of perforation. 200529947 Regarding the technology for locally supplying a lubricating liquid, JP-A-7-112227 described above discloses a die device capable of locally supplying press working oil to a front end portion of a punch used in a screeding step. , And part of the material to complete the stamping process. In addition, the above-mentioned 5 JP-UM-A-61-102323 discloses a perforated punch capable of locally supplying lubricating oil to the perforated punch which slidably contacts a shearing surface of a material which is a processing body. An outer periphery of a front end portion. In addition, conventionally, the punching punches used in the stamping processing of the heat sink fins are used together with the hydrocarbon-based lubricating oil 10, and JP-A-7-112227 described above. An extruded member (knock out) is the same, and a lubricating oil path is arranged in the punching punch, so that the lubricating oil can be locally supplied to the outer periphery of the front end portion of the punching punch. As shown in Fig. 12, this conventional punching punch works in conjunction with a reaming punch as a master die. 15 It is obvious from Fig. 12 that a perforated punch 101 is provided with a lubricating oil control 133, which is internally connected in an axial direction from a base portion 117 to a front end portion thereof, and is opened in a radial direction. The lubricating oil injection hole 135 to the outer peripheral surface 113 of one of the punching punches is formed at the lower part of one of the base portions U7, so as not to interfere with the surface 20 within a receiving hole 128 of a reaming punch 102 (not Cooperate). According to this structure, the lubricating oil is locally supplied to the perforated punch 101)) and the outer peripheral surface 113. At this time, the reaming punch 102 has a conventional shape, and the receiving hole 128 thereof cooperates with the punching punch 101. However, the mold equipped with the traditional lubricating oil path and the lubricant spraying 200529947 perforation are not enough for practical use. When used with water and water-based lubricating liquid, due to the use of this traditional mold, Lubricant-coated aluminum plates are perforated and lubricated with a water-based lubricating liquid to lubricate the front ends of the hole punch 101 and the reaming punch 102 due to lack of lubrication (insufficient) and heat generation. The hole punch 102 is broken. In fact, by using this traditional mold, the perforation of the lubricant-coated aluminum plate is completed at a rate of 2000 to 2100 strokes per minute, and the mold will be subjected to about 92,000 strokes. damage. As shown in Figure 13, the scanning electron microscope (SEM) photograph shows the condition of the damaged conventional mold. In relation to FIG. 13A, it is found that the perforated punch 101 and the reamed punch 102 are exothermic, the front end of the reamed punch 102 is partially broken, and the fracture piece is fixed to the perforated punch. Surfaces around the head. FIG. 13B is an enlarged photo of the part surrounded by the box as shown in the 13ASI towel, and from this drawing, it is found that a 15 peripheral edge of the end part before the punch punch 101 is due to friction Or for similar reasons, it has an extremely rough surface. C Summary of the Invention 3 Summary of the Invention The present invention has been made in consideration of the foregoing problems, and an object of the present invention is to provide a die for press working, which can prevent mold from heating due to friction even when lubricating liquid using water and water as a base is used for lubrication. , And is sufficient for practical use and a stamping method. In order to achieve the above object, in the stamping die of the present invention, when the male die and the female die cooperate with each other to cut materials, as a main structure of the lubricating liquid tank at least temporarily storing the lubricating liquid, it is completely or partially 200529947 is separately formed on an outer peripheral surface of a partially overlapping portion of a male mold partially overlapping each other or an inner peripheral surface of a partially overlapping portion of a female mold. According to this structure, the lubricating liquid can be stored at least temporarily in a lubricating liquid pool disposed on the peripheral surface outside the male mold 5 or on the peripheral surface inside the female mold. If the lubricating liquid is stored in the lubricating liquid tank, the stored lubricating liquid system is adequately supplied to a part that requires special lubrication, for example, between a male mold and a female mold and between a male mold and a metal plate. Therefore, the frictional resistance in this part is reduced. In addition, because all or 10 parts of the lubricating liquid pool are formed in the heavy parts where the male mold and the female mold partially overlap each other, it can effectively lubricate and cool the male mold and the female mold that are the friction heat generating parts. The second part overlaps. In addition, according to the present invention, a concave portion is formed on at least a part of the outer peripheral surface of the partially overlapping portion of the male mold or the inner peripheral surface of the partially overlapping portion of the female mold as a lubricating liquid pool. According to this structure, an area where the male mold and the female mold are brought into sliding contact with each other is made smaller, so that the frictional surface of the mold can be reduced to prevent the generation of frictional heat. In particular, when at least a part of the lubricating liquid pool is formed at a surface around the surface outside the partially overlapping portions where the male mold and the female mold partially overlap each other, the mold and the metal plate (the material to be processed) are brought into sliding contact with each other. The area is made smaller so that frictional heat can be further prevented. In addition, if a water-based lubricating liquid is used as the lubricating liquid, since the specific heat system of the water-based lubricating liquid is high, the mold can be effectively cooled. 200529947 In addition, according to the present invention, a small diameter portion having an outer diameter smaller than the outer diameter of the front end of the male mold is formed on the peripheral surface outside the partially overlapping portion of the male mold as the aforementioned lubricating liquid pool. A large diameter portion having a diameter larger than the inner diameter of the edge of the open end of the female mold is formed on the inner peripheral surface of the overlapping portion of the female mold portion 5 as the aforementioned lubricating liquid pool. According to this structure, a small-diameter portion or a large-diameter portion can be made by cutting processing when manufacturing a mold, and a simple processing can provide a lubricating liquid pool with high lubricating ability and high cooling effect in the mold. In addition, according to the present invention, a lubricating liquid path for supplying lubricating liquid to the lubricating liquid pool 10 is arranged in a male mold or a female mold. According to this structure, the lubricating liquid flows through the lubricating liquid path, and the lubricating liquid can be reliably and efficiently supplied to the lubricating liquid pool. If the lubricating liquid path is formed from the base part to the inside of the male mold, then it is connected to the lubricating liquid pool formed at the peripheral surface outside the partially overlapping part of the male mold, and the lubricating liquid in the lubricating liquid pool flows through the male The inside of the mold can therefore more reliably and effectively supply the lubricating liquid to the lubricating liquid pool located on the peripheral surface outside the partially overlapping portion of the male mold. Therefore, according to the present invention, the lubricating liquid path includes an axial path formed from the base portion of the male mold along an axial direction, and a branch 20 path communicates with the axial path and is connected to a path including the male mold. Elongation to one side of the module; and a branch wall for redirecting the flow of the lubricating liquid from the axial direction of the male mold to the direction including the radial module, which is arranged in an intersection where the axial path and the branch path cross each other . According to this structure, the lubricating fluid system flowing through the axial path conflicts with a divergent 200529947 wall, and thus flows to a branch path. Therefore, it is further more reliable and effective to supply the lubricating liquid to the lubricating liquid pool located at the peripheral surface outside the partially overlapping portion of the male mold. Furthermore, according to the invention, at least a part of the peripheral edge of one of the lubricating liquid pools is chamfered. According to this structure, the lubricating liquid flows downward from the lubricating liquid pool toward the front end portion and the open end portion of the mold which has the largest load and requires the most lubrication, which is in contact with a metal plate such as a nameplate, and so on The lubricating liquid is easily supplied to the end portion before the mold and the end portion of the opening 10. Therefore, the mold-related lubrication ability and cooling ability are further improved, so that the mold can be prevented from generating heat. Furthermore, according to the present invention, the distance between the lubricating liquid pool and the front end portion of the male mold or the edge of the open end of the female mold is partially shortened. 15 20 According to this structure, the lubricating liquid pool is partially close to the front end portion and the open end portion of the mold with the maximum load. Therefore, in these households, the lubricating liquid pool towel can easily flow to the front end of the male mold.部 部 ^ and the open end portion of the master mold. Another too; With respect to the χ 1 blade force, it is possible to ensure the required degree of cutting and perforation of a metal plate such as a name plate at positions other than the front end portion of the male mold and the open end portion of the female mold. Therefore, it is possible to efficiently lubricate the front end portion of the male plate and the open end portion of the female mold while maintaining the strength required for the mold processing. This temple rice uses water or lubricating liquid with water-soluble lubricant dissolved in water towel as the base lubricating liquid as L㈣, which is enough to realize the ideal of coexisting with the natural environment in production 12 200529947, which can reduce manufacturing costs, processing equipment and Processing lines can be simple and miniaturized. Furthermore, when the hole is continuously formed multiple times on a thin metal plate by using the above-mentioned stamping die, the stamping method of the present invention may include a step of supplying a lubricating liquid to the lubricating liquid pool. When the mold and the female mold cooperate with each other during the period from the state where the male mold and the female mold cooperate with each other, at least temporarily, the lubricating liquid pool is completely or partially The ground is formed on the outer peripheral surface of a partially overlapping portion of the male mold that partially overlaps each other or on the inner peripheral surface of the overlapping portion of the portion 10 of the female mold. Therefore, it is possible to supply the lubricating liquid to the lubricating liquid pool for each punching cycle, and to store the lubricating liquid in the lubricating liquid pool at least temporarily for each punching cycle, thus improving when the male mold and the female mold cooperate with each other ' 15 Lubrication and cooling efficiency at the partially overlapping portions where the male mold and the female mold partially overlap each other. According to the die for punching according to the present invention, a lubricating liquid pool is formed in the male die or the female die, and the lubricating liquid is supplied to the front end portion of the die that needs to be sufficiently lubricated, and thus the lubricating effect can be improved. Furthermore, by disposing a lubricating liquid tank, the area of the friction portion of the mold can be made small. From 20, even when water and water-based lubricating liquids are used in the stamping process, the similarity can prevent heat generation due to friction of the mold, and even when water and water-based lubricating liquids are used in the stamping process. When the stamping oil or the like is used instead of the stamping oil, a stamping die sufficient for practical use can be provided. 13 200529947 In addition, according to the press working method of the present invention, since the above mold is used and the male mold and the female mold cooperate with each other when the lubricating liquid is stored in the > slip liquid pool, the parts of the male mold and the female mold are improved Lubrication and cooling efficiency at these overlapping portions. Therefore, even when a water-based lubricant having a low lubricating ability is used, it is possible to prevent disadvantages such as mold heating or the like due to friction, and to provide a punching method sufficient for practical use. At this time, according to the die for punching according to the present invention, even when using a lubricating liquid with water 10 as the base, which has a lower lubricating capacity than that of a hydrocarbon-based lubricating oil, it is expected that when using conventional hydrocarbons, When the compound is the base lubricant, it can prolong the service life of the mold.

I: Detailed description of the preferred embodiment 3 In relation to the drawings, the specific embodiments of the present invention will be described below. It should be noted that the present invention is not limited to these specific embodiments. 200529947 Specific Embodiment 1 Figure 1A is an enlarged longitudinal sectional view of a part of a first specific embodiment for press working of the present invention. The mold is used for perforation and reaming. In the molds shown in Figs. 1A to C, a 5-hole punch 1 as a male die is used for perforation in a metal plate to make the hole obvious, and as a Reaming punch 2. Perforated punches 丨 and reamed punches 2 are made of sintered carbide, respectively. The perforating punch i is configured as an upper die 5 and a round diebut 3 for reaming, which are arranged so as to surround the perforating punch 1 and the reaming punch 2 of the configuration. The lower die 6 is connected to the same stripper plate 10, which is arranged to surround the reaming punch 2. The perforated punch 1 and the reamed punch 2 are formed on a metal plate disposed therebetween, and a hole is formed by shearing force. After forming the hole, the perforated punch 丨 is fitted in the reamed punch 2. Therefore, the perforated punch 丨 and the reamed punch 2 cooperate with each other. The lubricating liquid pool 10 is arranged on the outer peripheral surface 13 15 of one of the punches 1. According to this specific embodiment, with regard to the lubricating liquid pool 10, a small diameter portion is formed whose diameter is smaller than an outer diameter at a front end portion 15 of a punching punch 1. FIG. 1B is an enlarged view of a range of partially overlapping portions i3a and 24a. When the punching punch 丨 and the reaming punch 2 cooperate with each other, the outer peripheral surface of the punching punch 1 and the reaming punch 2 The inner peripheral surfaces overlap each other by 20 minutes. As shown in Fig. 1B, the lubricating liquid pool 10 of the punch punch i is arranged on the outer peripheral surface of the partially overlapping portion 13a of the punch punch 1. According to this embodiment, the small-diameter portion configured as a lubricating liquid tank 10 is arranged at a position separated from the edge 15a of one of the front ends of the punching punch 1 in order to ensure that it is supported on the punching operation. Sufficient strength at a relatively large load through the 16 200529947 hole punch 1 part I5. The π perforated punch 1 has a lubricating liquid path 31 communicating with the lubricating liquid pool 10. The lubricating liquid path 31 formed by 'as shown in the figure' is formed by the punching body—the base part 17 to the inside of the perforated punch, and is used for the riding liquid formed on the surface of the part S of the heavy part 13a. Connected. The lubricating liquid path 31 of this embodiment is an axial path 33 along the -axis square structure !, and-with this axial path = = / σ test hole radius 1 Elongated branch path 35 10 15 20 At this time, 'this embodiment does not mean that the liquid path 31 can be constructed by 彳 ^, 纟. The structure and lubricating oil are composed of a path 33 formed on the perforated punching rule as a male mold, and a branch path (not shown) which is formed from an axial path 33 of a vertical m in the longitudinal portion and is connected to Including-one side in the radial direction is extended upwards, and it communicates with the moisturizing body pool 10. According to the present embodiment, the lubricating liquid path 31 is arranged at the position of the perforated contact 1 as the eight mold. "If lubrication is supplied to the lubricating liquid tank 10, the m㈣ path 31 may be disposed in either of the pure and the master mold. In addition, the riding path 31 may be placed inside the mold or outside the mold. Further According to this specific embodiment, the two branch roads are arranged in a half-up direction. However, if it is possible to sufficiently ensure the angle at the front end portion 15, the shots provide an appropriate number of branch paths, such as four or six branch paths. It is obvious from FIG. 1A that, in the branch path 35 of the present embodiment, 'its-part is opened at the small-diameter part 17 200529947 forming the lubricating liquid pool 10, and the other part is opened. At a position close to the leading edge 15a of the punching punch !, it is opened on the peripheral surface outside the punching punch. Therefore, an opening portion 35a of one of the branch paths 35 is made a part of the lubrication liquid pool 10, Therefore, a distance between the lubricating liquid 5 body pool 10 and the front end edge 15a of the perforating punch 1 at the opening portion 35a of the branch path 35 is partially short, and the lubricating liquid pool is constituted in this manner. 1〇 At this time, when the lubricating liquid pool 10 is provided in the master mold, the lubricating liquid pool can be constituted, so the distance between the lubricating liquid pool 10 and the end edge 26a of the master mold is made partially short. 10 In addition, the branch wall 37 is disposed inside the perforated punch 1 at a portion where the axial path 33 intersects with the branch path 35 (the branch portion of the branch path 35 branching from the axial path 33). At this time, according to this specific In the embodiment, the branching wall 37 is formed by making the axial path 33 located at the front end side of the perforation punch 1 narrower than the intersection with the branching path%. However, the branching wall 15 37 is formed so that the shaft The direction path 33 terminates at the branch wall 37. Here, in relation to FIG. 1C, an example of these sizes of the punch punch j as a reference is explained. In this example, one of the front end portions of the punch punch 丨The diameter d is 4 · 8 mm, and the length from the edge of the front end portion to the small diameter portion in an axial direction is 2 mm. In the small 20-diameter portion serving as the lubrication liquid pool 10, the axial direction The length h is 3. 5 mm, the depth of a recess of the surrounding surface from the partially overlapped portion is 0.2 mm (f) in the lc figure, and a diameter (outer diameter) s of the recess is 4. 4 mm. Therefore, in this example, the volume of the lubrication liquid pool 10 is about 10. llmm3, and the lubricating liquid can be stored in the lubricating liquid tank 10 according to this volume. In addition, with respect to the diameter of the axial path 33 in the lubricating liquid path 31 of 18 200529947, the straight line from the base portion 17 to the branch wall 37 is 1 = 2 mm, and from the branch wall π to the front end of the perforated punch 1 The diameter of the part is e = 1 mm. Furthermore, the straight and diameter j of the branch path 35 is 1. 5 mm. 5 The reaming punch 2 as the female die is open, and the inner diameter is slightly larger than the outer diameter of the front end portion 15 of the punching punch 1, and has a receiving hole 28 for receiving the front end of the punching punch 1. Ministry section. The inner peripheral surface 24 of one of the receiving holes 28 has a part of the inner peripheral surface of the overlapping portion 24a. When the punching punch 1 and the reaming punch 2 cooperate, a part of the overlapping part with the punching punch The surrounding surface partially overlaps and slides into contact. In addition, the two stepped portions 44 and 45 are arranged downward from the inner peripheral surface of the partially overlapping portion 24a of the receiving hole 28, so the downward inner diameter is larger and a hole is formed in the metal plate by the punching punch i. A metal element produced at this time is easy to fall from the reaming punch 2. 15 Next, the operation of the die device for perforation and reaming shown in Figs. 1A to 1c will be described. In this example, according to this specific embodiment, the bottom direction in Figure 1 is to insert a punch punch! One direction, and one up direction are the directions to pull out the # 孔 冲 头 1. A metal plate, such as a lubricant-coated aluminum plate or the like, which is one of the materials of the heat radiation fins, is mounted on the stripper plate 4, and then, the upper mold 5 and the lower plate. The front end edge 15a of the perforated punch 1 is in contact with the metal plate, and thereafter, the metal plate is placed between the round punch 3 and the stripper plate 4. The perforated punch is further down, and when the front end portion 15 of the perforated punch is matched with the receiving hole 28 of the reaming punch 2, the metal plate is sheared to form a hole. 19 200529947 After forming a hole, when the punching punch 1 moves upwards, the reaming punch 2 also moves upwards. Due to this upward movement, the peripheral edge of the hole constituting the metal plate is pushed up by a push-up portion 42 arranged at a front end portion% of one of the reaming punches 2, and the push-up portion 42 and the round punch One of the heads 3 is a reaming 5 receiving portion 46 to complete the reaming operation. After that, the upper die 5 moves upward and the reaming punch 2 moves downward. The punching and reaming processing metal plate is removed from the reaming punch 2 by the stripper plate 4, and thus the perforating and reaming steps are ended. Next, with reference to Figs. 2 and 3, the effect of the lubricating fluid / membrane at the time of perforation will be described below. Fig. 2 shows the state in which the punching punch 1 and the reaming punch 2 of the stamping die 10 are matched in Fig. 1, and the figure 3 is eight-blade opening. status. By means of a pressure supply device (not shown) such as a gear pump or similar device, the lubricating liquid is supplied from a tank (not shown) through a tube ", die > The base portion 17 flows downward through the axial path 33, and the liquid is partially redirected to a branch path 35 communicating with the lubricating liquid pool 10 through a 15-blade manifold wall 37. Preferably, the body is supplied to the lubricating liquid tank 1G 'so that no gas is contained in the lubricating liquid as much as possible, because if the lubricating liquid tank 10 is a lubricating liquid which does not contain gas, V ,, riding, for example, with the supplied Compared with the spraying condition of the lubricating fluid system, the cooling capacity becomes higher. 20 Qu Shikou Chu 2㈤ Tian Le j When the molds shown in the figure are separated, the slip fluid system supplied to the lubricating fluid 'also 10' is along the peripheral surface of the partially overlapping portion 13a of the punch 1 Flow to lubricate the front end portion 15. When the plate 4 and other plates cooperate with each other, the inner peripheral surface of the partially overlapping portion 4a of the reaming punch 2 is in contact with the lubricating liquid stored in the lubricating liquid pool 20, 2005 29947. The outer peripheral surface of 13a and the inner peripheral surface of the partially overlapping portion 24a of the reaming punch 2 flow between the partially overlapping portions of the punching punch 1 and the reaming punch 2, respectively. · In addition, if the lubricating liquid is supplied to the 5 mold under high pressure according to the time of boring, the powder generated when the metal plate is sheared is lubricating liquid fed by pressure from the perforated punch 1 and expanded. The hole punches 2 are pushed away. Therefore, the cutting powder is prevented from adhering to the mold that is engaged between the punching punch 丨 as a male die and the reaming punch 2 as a female die, and thus it is possible to avoid a contribution. 10 As described above, 'the branch path 35 of this embodiment is opened near the edge 15a of the front end of the punching punch 1 instead of being a small-diameter portion of the lubricating liquid pool 10. In other words, the lubricating liquid pool 10 is constructed so that a distance between the lubricating liquid pool 10 and the front end edge 15a of the perforated punch 1 at the opening portion 35a of the branch path 35 is partially short 15. On the other hand, the moisturizing / bone fluid easily flows to the front end edge 15a, rather than to the portion of the moisturizing body pool 1 () made into a smaller diameter portion at the opening portion 35a. As clearly seen in Figure 2, when the molds cooperate with each other, stay away from the perforation. The end portion of 5 a (the upper end portion of the small diameter portion 20 knives) is located at the upper edge position of the end edge of the reaming punch 2 and constitutes the small diameter portion of the lubricating liquid pool 10 in this way. In the self-branching path 35, the lubricating liquid not only flows from the lubricating liquid Chi Qing to the edge 15 of the punching punch 1, but also from the end edge (upper edge) 26a of the reaming punch 2 through the lubricating liquid and the reaming punch. The head portion partially overlaps the portion 21 200529947 and flows outward between the peripheral surfaces 24a to the reaming punch & while lubricating and cooling the front end portion of the reaming punch. You 丨 by, the ice field: the reason Dong Shi from a 4h part. From this example, when water and water containing water are used as the base liquid, since water is used as the base liquid as the base liquid, it is possible to achieve a relatively smooth, human / ,,,,, and coincidentally use oil. L ,, ,, θ ^ I Xi Wenguo 10 15 20 At this time, it is preferable that, as the upper end portion of the lubricating liquid pool 10, the position of the upper end portion of the lubricating liquid pool 10 should not be in contact with the plate as a direct inspection portion. Because the contact with the metal plate will cause the unnecessary metal to be affected by the ugly and harmful powder. In addition, as can be clearly seen in Figure 2, the perforated punch is standing before the punch. 15 slidingly touches the inner overlapping part of the partially overlapping part 24a of the reamer punch 2. However, since the lubricating liquid pool 10 is connected to the outer surface σ and the surrounding surface, the lubricating liquid pool does not overlap with the part. The part 24a 糸 is a four-in-plane contact. "In other words, the friction between the male mold and the female mold can reduce excessive friction. Therefore, the friction can also be prevented from being reduced. By using the stamping mold and the mold of this first embodiment, Water is used as the base liquid for lubricating liquid, and the perforating operation is performed at a rate of 200 to 210 strokes per minute (percussion). Therefore, irreparable damage is not caused in the mold, but only in the male mold. There is some slight friction in the front end portion of the master mold. Compared with the example of using a hydrocarbon-based lubricant as the stamping processing oil, the friction of the metal mold is not bad. Figures 4A and 4B show that After 100,000 shots, the SEM photograph of the mold. Here, Figures 4A and 4B correspond to Figures 13A and 13B, respectively. Related to the traditional mold shown in Figure 13, comparing these SEM photos, we can understand The lubricating ability has been improved. 22 200529947 On this day t 'can supply lubricating liquid from one tank to the stamping die' alternately and intermittently supply lubricating liquid from one slot to the stamping die. Examples of lubricating fluid is supplied intermittently in the profile can be -㈣. The cam and the encoder or similar are adjusted when the rotary axis of the induction press is moved *. 5 supply of lubricating liquid. For example, assuming that the upper die-top dead point (center) is 0 degrees, the lubrication liquid can be adjusted to be supplied to the mold at a rotational position from 170 degrees to 185 degrees including the lower dead point (discussion). Lubricate the liquid pool). Specific Embodiment 2 φ 10 Hereinafter, another specific embodiment of the present invention which is different from the specific embodiment of the previous embodiment will be described with reference to FIG. 5. Fig. 5 is an enlarged longitudinal sectional view of a part of a second embodiment of a press working die of the present invention applied to a die device for perforation and reaming. This stamping die is different from the 15 die for stamping in the first embodiment, except that the lubricating liquid pool is not formed on the outer peripheral surface of the partially overlapping portion of the punch punch, but is located in the enlarged hole. 0 of the punch on the inner peripheral surface. Therefore, the same representative symbols are the same elements in Figs. 1 and 5, and detailed descriptions thereof are omitted here. In relation to FIG. 5, the lubricating liquid pool 10 is formed on the peripheral surface 24 inside the reamer punch 2. The lubricating liquid pool 10 is constituted by providing a large-diameter portion on the inner peripheral surface of the partially overlapping portion 24a of the reaming punch 2 with an inner diameter larger than that of the end edge 26a of the reaming punch 2. On the other hand, the outer diameter of the perforated punch 1 shown in FIG. 5 from the lower edge to the front end edge 15a of the base portion 17 of the perforated punch 1 is the same as the outer diameter of the front end 23 200529947 part edge 15a. Inside the perforated punch 丨, a lubricating liquid path 31 formed by an axial path 33 and a branch path 35 is formed. At the part where the axial path 33 and the branch path 35 intersect, a branch wall "is arranged to redirect a part of the lubricating liquid to a diameter direction. 玎 Only-, me m 月 豆 、 狂 ty Hayada 冋 bathing: ^ The branch wall conflicts and emerges from the opening 3 of the outer peripheral surface 13 of the perforated punch of the branch path 35. Therefore, the lubricating fluid flowing from the branch path 35 when the perforated punch 1 and the reamed punch 2 cooperate with each other. The system is supplied to the body of the reaming punch 2, the door 1 10:

In this case, if the surface of the lubricating body pool 10 is guarded to be thicker than the reamed hole, the silk surface is rough. ^ The surface tension of the sliding liquid can better hold the lubricating liquid. In addition, when the punching punch 1 moves into and out of the receiving hole 28 of the reaming punch 2 the lubricating liquid flowing in the part 35a can lubricate the punching punch] part = 13a outer peripheral surface, and part of the reaming punch 2 overlaps部 ， 部 Ｍ peripheral surface. Therefore, in the second embodiment of the punching tool ^ can also fully lubricate the mold and the processing department needs to be lubricated.

Therefore, the area of the friction portion of the mold is made small to prevent excessive friction.俾 便 / ¾ Specific Embodiment 3 24 200529947 Furthermore, a third specific embodiment of the present invention will be described with reference to FIG. 6. FIG. 6 is an enlarged longitudinal cross-sectional view of a part in an adjacent area of an end portion before a punch punch, and a chamfered lower edge is formed in the same stamping die as the first embodiment of the present invention. Lubricates the small diameter portion of the liquid pool 5. This perforated punch is different from the first embodiment described above, except that the lower edge of the small-diameter portion constituting the lubricating liquid pool 10 is chamfered. Therefore, the same representative symbols are the same elements in FIGS. 丨 and 6 and detailed descriptions thereof are omitted here. In relation to FIG. 6, a chamfered portion 51 having an arcuate portion is arranged 10 at the lower edge of the small-diameter portion of the lubricating liquid pool 10 constituting the perforation punch 1. Therefore, since the lubricating liquid supplied to the lubricating liquid tank 10 via the lubricating liquid path 31 flows easily through the chamfered portion 51, the front end portion 15 is easy to receive lubrication. The chamfered portion 51 is arranged so that the contact portion with the inner peripheral surface of the reaming punch is made smaller, and when the 15-hole punch 1 is pulled out from the reaming punch 2, the action of the punch 1 can be prevented. Break. At this time, according to the third embodiment, the chamfered portion 51 俾 has a circular arc portion. However, the chamfered portion 51 may be formed in a push shape. In addition, the chamfered portion 51 may be formed not only at the lower edge of the lubricating liquid pool, but also at the entire peripheral edge, or the chamfered portion 51 may be disposed only at a part of the peripheral edge of the wet liquid pool. Specific Embodiment 4 Next, Figs. 7A to E show examples of different lubricating liquid pools formed in a perforated punch as a male die. The lubricating liquid pool arranged in the male mold can be provided with a pushing portion, a concave portion, a stepped portion, and a groove at least a part of 25 200529947 arranged on the outer peripheral surface of a partially overlapping portion of the male mold. The slot is either any part of a similar part or any combination. Therefore, according to the mold, the strength of the mold or the design of the press, or the degree of lubrication required for a similar situation, a push portion, a concave portion, a stepped shape arranged at the outer peripheral surface of the partially overlapping portion of the male mold Any part, or any part of a groove or a similar part or any combination, can be selected as the shape of the lubricating liquid pool. In addition, these push portions, concave portions, stepped portions, grooves or similar portions may be arranged at a part of the outer peripheral surface of a partially overlapping portion of the male mold, or may be arranged so that the entire portion is partially overlapped. The outer peripheral surface of the part. Fig. 7A shows an example in which the lubricating liquid pool 10 is arranged as a front end portion 15 of a perforated punch 1 constituted as a pushing portion. Fig. 7β shows an example in which a plurality of elliptical concave portions are formed on the peripheral surface outside the perforating punch i to make a sliding liquid pool. Furthermore, as for a recessed portion of the lubricating liquid 15 body pool 10, the opening portion of the branch path can also be used. Fig. 7C shows an example in which a stepped portion in # is arranged at a portion separated from the front end edge 15a by a predetermined distance to constitute the lubricating liquid pool 10. Figure TD shows an example in which the lubricating liquid pool 10 is formed in the perforation by a plurality of right-numbered grooves or spiral grooves arranged in a horizontal direction relative to the edge of the front end of the perforation punch 1. Punch with. In addition, FIG. 7E shows an example in which a plurality of longitudinal grooves extending upwardly at a predetermined distance from the front end portion are arranged to make a lubricating liquid pool 10. In this example, the supply of the lubricating liquid to the upper part of the longitudinal groove can also be performed by using the longitudinal groove to supply the lubricating liquid from the upper part to the lower part of the longitudinal groove 26 200529947. At this time, the examples shown in FIG. 7A ^ are that the lubricating liquid pool 10 is configured differently in the punch punch as a male mold, however, different shapes of the lubricating liquid pool can be arranged in the female mold. Part weight ^. Part on the inner peripheral surface. / 刀 外 ’in Figure 7’ is not in the punch! The lubricating liquid is shown in the figure. However, similar to the above-mentioned specific embodiments, a lubricating liquid path may be arranged in the perforated punch 1 or the reamed punch 2. * Yu, 忐 is enough to form different lubricating liquid pools. According to the stamping process, the degree of lubrication required by the mold, the strength of the mold, or the design of the press or similar conditions are selected for the lubrication of the male or female mold. The shape of the liquid pool. Specific Example 5 Next, Figs. 8, 9 and 10 show an example of a die for press working, which has different lubricating liquid pools for supplying lubricating liquid. In relation to Fig. 8, inside the stripper plate 4, a lubricating liquid path 15 diameter 62 is arranged as a spray path, and the lubricating liquid can be sprayed toward the lubricating liquid pool 10 of the perforated punch. The lubricating liquid path 62 extends from a portion above a surface 64 of the reamer punch 2 of the stripper plate 4 in an oblique direction, and extends to the base portion of the stripper plate 4. In the stamping die shown in FIG. 8, the lubricating liquid sprayed from the self-lubricating liquid path 62 at a suitable time course, and the lubricating perforation punch} the front end portion 15 ′ Furthermore, the lubricating liquid system is temporarily It is stored in the lubricating liquid pool ι0, so it can fully maintain the lubricating liquid required for stamping. Fig. 9 is an example of a die for press working, in which a lubricating liquid path 61 is located in the round punch 3. As shown in Figs. According to Fig. 9, the lubricating liquid path 61 27 200529947 is extended from the base portion of the circular punch 3 to the reaming receiving portion 46 in an oblique direction, and the lubricating liquid path 61 is opened at the reaming receiving portion 46. The lubricating liquid sprayed from the reaming receiving portion 46 is spread to the lubricating liquid pool, 10, the front end portion of the perforation punch 1, 5 or the front end of the reaming punch 2, 5 part 26, and then lubricated. Those parts. In addition, by storing the lubricating liquid in the lubricating liquid tank 10, the lubricating liquid required for the press working is secured. Fig. 10 is an example of a die for press working, in which the lubricating liquid path control 72 is arranged inside the reaming punch 2 as a master die. In Fig. 10, the "lubricating liquid pool 10" is arranged in the female mold. The lubricating liquid path 72 is φ 10, which is elongated, and is used to communicate with the lubricating liquid pool 10 from the base portion of the reaming punch 2. . Accordingly, the lubrication liquid can be directly supplied to the lubrication liquid pool 10. On this day, as far as the lubricating liquid pool 10 is arranged in the perforated punch 1 as the male die, the lubricating liquid path π is arranged in the reaming punch 2 as the female die on the same day. The surrounding surface inside the partially overlapping portion 24a is elongated, and is opened at the surrounding surface inside the partially overlapping portion 24a. Therefore, the inner peripheral surface of the reaming punch is sufficiently lubricated, and further, when the hole punch 1 and the reaming punch 2 cooperate with each other, the lubrication liquid is supplied to the lubrication liquid pool 1 of the punch 1 〇. In addition, the self-lubricating liquid path 270 72 sprays the lubricating liquid to the perforated punch and lubricating liquid pool 10. Due to the "spraying of the idle liquid", the lubricating liquid supplied to the lubricating liquid pool 10 is stored there, and at the same time, the lubricating liquid can be supplied to the front end portion of the punch 1. @ According to the examples shown in Figures 8 and 9, the lubricating liquid pool 10 is configured in 28 200529947 as the punch punch 1 of the male die. However, the lubricant liquid pool is formed in the female die, and the 8th and 9th can be configured. The lubricating fluid path shown in the figure. In addition, according to the examples shown in Figs. 8, 9 and 10, the lubrication liquid path is not arranged in the punching punch 1 as a male die, however, it can be used simultaneously in Figs. 8, 9 5 and 10 respectively. The lubricating liquid path and the lubricating liquid path arranged in the perforated punch 1 as a male die are shown. Furthermore, the different perforated punches 1 shown in Fig. 7 can also be constructed as the perforated punches 1 shown in Figs. 8, 9 and 10. At this time, they are used to lubricate in the lubricating liquid pool. For a lubricating liquid supply device that supplies 10 lubricating liquid in the liquid path, for example, it has a pressure feeding device such as a gear pump or the like (not shown in the first to fifth embodiments described above). The lubricating liquid supply device can be suitably arranged inside a press, or in a component surrounding the press. In addition, according to the specific embodiment described above, it is merely explained that a mold such as a 15-hole punch or the like is made of sintered carbide. Superhard alloys which may include a hard carbide particle such as tungsten carbide (WC) and titanium carbide (Tie) or the like, and an iron such as cobalt (Co) and nickel (Ni) or the like A binder phase metal made of a group metal. In addition, as the water-soluble lubricant, an organic phosphide compound and an organic metal salt can be used. Furthermore, it is preferred that the water-based lubricating liquid may contain a metal activity inhibitor: to prevent the cementitious phase metal and solid from the cemented carbide used in the mold, because the metal activity inhibitor prevents Sintered carbides are corroded due to the dissolution of the metal in the binder phase. 29 200529947 The stamping die and the stamping method of the present invention have advantages in performing boring and cutting operations on the material of the main body by using the rabbit force of the male die and the female branch.
