1313197 九、發明說明： 【發明所屬技術領威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· ^tr Ί 10 發明背景 傳統上，如第11Α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(collar);以及 一再呈喇叭形展開(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（platefin)。 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。於衝壓加工令，有關於潤滑的先前 技術，例如，係揭露在JP_A_7_112227及jp_um_a_6i_i〇2323 中’並將於之後說明該等先前技術。 1313197 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氣溶劑加以淨化。 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 1313197 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0.1公 厘。根據在本發明製作之前已完成的先期研究，所得結論 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 队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， 該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 滑劑塗佈的紹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。 1313197 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Μ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-加工主體的材料的—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—擠製構件 (頂出具(knock out))相同，在穿孔衝頭中配置一濶滑油路 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 路徑133，於内部係於一軸方向上由一底座部分117貫穿至 其之一珂端部部分，以及一於徑向上開啟至穿孔衝頭101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）。 根據該一結構，將潤滑油局部地供給至穿孔衝頭101 之鈾h D卩邛分及外周圍表面113。此時，擴孔衝頭具有 一傳統形狀，其之接受孔128與該穿孔衝頭101配合。 然而’配置該傳統式潤滑油路徑的模具以及潤滑油喷 1313197 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 劑塗佈之銘板完成穿孔同時以水為基體的潤滑液體潤滑， 則穿孔衝頭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1〇2斷裂。 實際上，藉使用該一傳統式模具，在每分鐘200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 九萬二什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況。相關於第13A圖，所發現的是該穿孔衝頭1〇1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13A圖中所示的一方塊所環繞的一部分的一放 大相片，並由此圖式，發現穿孔衝頭101之前端部部分的一 I5周圍邊緣，因摩擦或相似原因而具有一極為粗糙的表面。 【發明内洛】 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 20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 其中至少暫時地儲存’/閏滑液體的一主要結構，係完全或部 1313197 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 的該等部分重疊處，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。 10 1313197 此外，根據本發明，外徑小於公模之前端部之朴的 —小直徑部分’係構成在公模之部分重疊部分之外周„ 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—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-結構，小直徑部分或大直經部分能夠在製造 模糾藉由切削加工而製成，並且藉由簡單的加工，能夠 在核具中提供具雨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 1〇的一潤滑液體路徑，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/閏/月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 2 〇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 1313197 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 為與諸如鋁板的金屬板接觸的一部分，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 10 端部部分。因此，進一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其中介於 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 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，因此於該等部分處， 潤滑液體池中的潤滑液體輕易地流至公模之前端部部分及 母模之開口端部部分。另一方面，在公模之前端部部分及 母模之開口端部部分以外位置處，能夠確保將諸如鋁板的 20 金屬板切削及穿孔所需的強度。因此，能夠有效地潤滑公 模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。 此時，假若使用水或是具有於水中溶解的水溶性潤滑 劑的水為基體之潤滑液體作為潤滑液體，則能夠實現生產 12 A^13l97 與自然if护_ 4 兄和為共存的理想，能夠降低製造成本，加工步 夏及力Π工/4_ 衣 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 上多次速缽 得1屬扳 5 哽項地構成孔時，本發明之衝壓加工方法可包括一 α潤滑液該潤滑祕池的㈣，在&公模與賴相 ' M S的狀g至其於第二位置相互配合的—狀態的該一 /間’當公模與母模相互配合其巾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 ㈣公模之部分重疊部分的外周圍表面上或是母模的❹ # 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。 根據本發明之衝藶加工用模具，藉由在公模或母模中 構成濁滑液體池，將调滑液體供給至需要充分潤滑的模具 · 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。曰從 而，即使當於衝壓加工中使用水及水為基體的濁滑液體或 相似物時，亦能夠防止因模具之摩檫而發熱，以及即使# ' 於誠加工中使用水及水為基體的聘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誠加工用 模具。 13 1313197 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潤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 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 擴孔用模具的一部分放大的縱向斷面圖。 15 第2圖係為一部分放大的縱向斷面圖，圖示配裝於第1

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 一穿孔衝頭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1及擴孔衝頭2係分別 以燒結碳化物製成。該穿孔衝頭1係構形為一上模5連同一 擴孔用圓衝頭(die button)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 鲁 10 (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i配裝 在擴孔衝頭2中，因此該穿孔衝頭1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13a及24a的一範圍的 一放大視圖，其中當穿孔衝頭1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1]8圖中所示，穿孔衝頭1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。根攄 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 1313197 孔衝頭1之前端部部分15處的足夠強度。 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 孔衝頭之一底座部分17至穿孔衝頭之内部，用以與構成在 5 部分重疊部分13a的外周圍表面上的潤滑液體池10連通。本 具體實施例之潤滑液體路徑31係藉由沿著一軸方向自一底 座部分17所構成的一軸向路徑33，以及一與此軸向路徑33 連通並係沿著穿孔衝頭1之一半徑方向伸長的分支路徑35 所構形。 10 此時，本具體實施例並不限定在該一結構，以及潤滑 液體路徑31可藉由構成在作為公模的穿孔衝頭1上的轴向 路徑33構成，以及分支路徑(未顯示）其係自一縱向部分中一 呈倒Y狀的軸向路徑33所構成，並係在包括一半徑方向的一 方向上伸長，俾便與潤滑液體池10連通。 15 根據本具體實施例，潤滑液體路徑31係配置在作為公 模的穿孔衝頭1之内部。然而，假若潤滑液體能夠供給至該 潤滑液體池10，則潤滑液體路徑31可配置在公模及母模的 任一者中。此外，潤滑液體路徑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，二分支路徑35 20 係配置在半徑方向上，然而，假若能夠充分地確保在前端 部部分15處的強度，則可提供適當數目之分支路徑35，例 如，四或六分支路徑。 由第1A圖中明顯可見，於本具體實施例之分支路徑35 中，其之一部分係於構形該潤滑液體池10的較小直徑部分 1313197 處開啟，以及其之另一部分係在與穿孔衝頭1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3 5之一開口部分3 5 a成為潤滑液體池丨〇的 一部分，因此，在分支路徑35之開口部分35a處介於潤滑夜 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10。 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10因此介於潤滑液體池10與母模之端部邊緣 之間的距離係部分地製成短的。 1〇 此外’一分歧壁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交叉的一部分處（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 位在穿孔衝頭1之前端部側的軸向路徑33較與分支路徑35 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1之該 等尺寸的一實例。於此實例中，穿孔衝頭1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10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0.2公厘（第1C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10.11mm3，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 1313197 濁滑液體路徑31令轴向路徑33之直徑，由底座部分17至分 歧壁37之直徑係為i=2公厘，以及由分歧独至穿孔衝頭ι 之前端部部分的直徑係為e=1公厘。再者，分支路徑^之直 徑j係為1.5公厘。 5 ㈣母模的擴孔衝頭2係為開啟的，其之内徑係稍大於 穿孔衝則之前端部部分15的外經，並具有一接受孔则以 接受穿孔衝則之前端部部分。接受孔28之一内周圍表砂

Description of the Invention: [Technical Field of the Invention] Field of the Invention The present invention relates to a die for press working for cutting 5 machining or boring processing of a metal plate or the like, more specifically Accordingly, the present invention relates to a die for press working of a fin for manufacturing a heat exchanger of an air conditioner or the like, and a press working method using the same. L·^tr Ί 10 BACKGROUND OF THE INVENTION Conventionally, as shown in Fig. 11, a heat sink for an air conditioner for an automobile and a heat exchanger for an indoor air conditioner or the like is manufactured by press working. The stamping process is mainly composed of the following steps: a preforming step for making a 15 metal plate such as an aluminum plate or the like easy to process; a piercing and burring step for drilling and Reaming the preformed metal sheet; an ironing step for forming a collar from a protruding portion around the hole in the metal plate; and a reflaring step for the rewinding step One of the front end portions constituting the collar is curved. The plate fins as shown in Fig. iiB are formed by applying the stamping to a metal plate such as an aluminum plate or the like. According to this press working, lubrication of the mold and the metal plate is important in order to improve the processing ability. For the stamping process, prior art regarding lubrication, for example, is disclosed in JP_A_7_112227 and jp_um_a_6i_i〇 2323' and the prior art will be described later. 1313197 At present, a lubricant based on a hydrocarbon is used for the lubrication in the press working of a heat sink for manufacturing a heat exchanger or the like. Hydrocarbon-based lubricants have been widely used as a lubricating fluid to coexist harmoniously with the global environment, because unlike the 5 mineral oil-based lubricants used before that, hydrocarbons are the matrix. The lubricating oil does not need to be purified by an organic solvent. In the case of performing press working using a hydrocarbon-based lubricating oil, in view of the manufacturing efficiency of the heat sink, the lubricating oil adhered to the heat radiating sheet is heated after the processing to evaporate and dry the lubricating oil. Therefore, in order to prevent the lubricating oil which vaporizes 10 vaporized hydrocarbons into the atmosphere, it is necessary to carry out treatment by catalytic combustion. Further, the lubricating oil relating to the hydrocarbon used in the press working as the base material can be recovered as a liquid, and a prescribed disassembly is required when industrially discharging. In this case, when hydrocarbon-based lubricants are used, post-treatments such as catalytic combustion and separation devices are extremely expensive when industrial emissions or 15 similar conditions occur. In addition, in response to the global environmental protection in recent years, it is necessary to have a lubricating fluid that is more harmonious with the global environment. In recent years, a technique has been developed for the use of water or water as a matrix-based lubricating fluid, which is a water-soluble lubricant dissolved in water for metal treatment such as cutting or similar processing, replacing hydrocarbons. A lubricant for the substrate. If the lubricating fluid based on water and water is used for lubrication in the press working, the catalyst combustion and separation device when industrial discharge is reduced, and the product can coexist harmoniously with the natural environment. In addition, the post-treatment after the use of the lubricating liquid can be reduced, so that the manufacturing apparatus and the production line can be miniaturized, and the cost is extremely reduced. However, the problem of water and water as a matrix lubricating fluid is that its lubricating ability is inferior to that of a hydrocarbon-based lubricating oil. On the other hand, according to the manufacturing industry of the heat sink 5 of a heat exchanger or the like in recent years, in order to improve the lubricating ability, a lubricant-coated aluminum plate is used as a processing material for the heat sink, wherein 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 a preliminary study that has been completed prior to the fabrication of the present invention, it has been concluded that the lubricant-coated aluminum sheet is used in the stamping step, in addition to the lubricating liquid based on water and water, except In addition to the perforating step, there is no problem in the pre-forming step, the reaming step, the ironing step, and the re-integration step. However, in the perforating step, even if a lubricant-coated aluminum plate is used, the aluminum portion exposed at the shear surface and the mold are directly in contact with each other. Therefore, the problem is that the steps are repeated, and the mold and the master mold are heated due to heat generated by friction or the like, and the mold is damaged (refer to Fig. 13). Further, according to a prior study by the inventors of the present invention, it has also been found that a lubricant coating coated with a lubricant is made of a water-soluble material such as ethylene glycol or the like, so that if water or A lubricating liquid containing a large amount of water as a base, and when the amount used for a flat plate as a processing main body is large, the lubricant coating is washed away to impair the lubricating ability and influence the joining step. Therefore, it seems to be effective to locally supply a lubricating liquid to a portion requiring a lubricating liquid at the time of perforation. In the above-mentioned JP-A-7-112227, a mold apparatus capable of partially supplying the press working oil to a front end portion of the punch used in the ironing step is disclosed in the above-mentioned JP-A-7-112227. And part of the material that completes the punching process. In addition, the above-mentioned 5 JP-UM-A-61-102323 discloses a punching punch capable of locally supplying lubricating oil to a front end of a punching punch slidably in contact with a shearing surface of a material which is a processing body. An outer part of the part. Further, conventionally, a punching punch used in the press working of a heat sink for a heat exchanger is used together with a hydrocarbon-based lubricating oil 10, and JP-A-7-112227 described above. The disclosed - the extruded member (knock out) is the same, and a lubricating oil path is disposed 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, the conventional perforating punch operates together with a reaming punch as a master. As is apparent from Fig. 12, a perforating punch 101 is provided with a lubricating oil path 133 which is internally connected in an axial direction from a base portion 117 to one of the end portions thereof, and is opened in the radial direction. The lubricating oil injection hole 135 to the outer peripheral surface 113 of the perforating punch 101 is formed in a lower portion of the base portion U7 so as not to interfere with the surface of a receiving hole 128 of a reaming punch 102 (not matched). . According to this configuration, the lubricating oil is locally supplied to the uranium and the outer peripheral surface 113 of the punching punch 101. At this time, the reaming punch has a conventional shape, and the receiving hole 128 is engaged with the punching punch 101. However, 'the mold for arranging the conventional lubricating oil path and the lubricating oil spray 1313197 perforating are not sufficient for practical use' when used together with water and water-based lubricating fluids' because the use of this conventional mold is related to The lubricant coated coated plate is perforated and lubricated with a water-based lubricating liquid, and the front end portion of the punching punch 101 and the reaming punch 102 is heated due to lack of lubrication (sufficient), thus causing the reaming The punch 1 〇 2 breaks. In fact, by using the conventional mold, the perforation of the lubricant-coated aluminum sheet is completed at a rate of 200 to 21 Torr per minute, and the mold is damaged by about 20,000 shots. As shown in Fig. 13, the scanning electron microscope (SEM) photograph shows the condition of the damaged conventional mold. Referring to Fig. 13A, it is found that the perforating punch 1〇1 and the reaming punch 102 are heated, the front end portion of the reaming punch 1〇2 is broken, and the breaking member is fixed to Perforate the outer surface of the punch. Fig. 13B is an enlarged photograph of a portion surrounded by a square shown in Fig. 13A, and from this figure, an I5 peripheral edge of the front end portion of the punch punch 101 is found, due to friction or the like. The reason is that it has an extremely rough surface. SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing problems, and an object of the present invention is to provide a die for press working which can prevent friction due to friction even when lubricating with a lubricating liquid of 20 substrates using water and water. The mold is hot and is available for practical use as well as a stamping process. In order to achieve the above object, in the die for press working of the present invention, when the male mold and the master mold are matched to each other for cutting the material, as a lubricating liquid pool, at least temporarily storing a main structure of the '/slip liquid, The full portion 1313197 is formed on an outer peripheral surface of a partially overlapping portion of the male mold partially overlapping each other or an inner peripheral surface of a portion overlapping portion of the female mold. According to this configuration, it is possible to at least temporarily store the lubricating liquid in a lubricating liquid pool disposed on the peripheral surface of the outer mold 5 or the inner peripheral surface of the female mold. If the lubricating fluid is stored in the lubricating liquid pool, the stored lubricating fluid system is sufficiently supplied to a portion that is particularly lubricated, for example, between the male mold and the female mold and between the male mold and the metal plate. Therefore, the frictional resistance in this part is reduced. In addition, since all or a part of the lubricating liquid pool is formed at the partial overlap where the male mold and the female mold partially overlap each other, the male mold and the female mold which are the friction heat generating portions can be effectively lubricated and cooled. The two parts overlap. Further, according to the present invention, a concave portion is formed as a lubricating liquid pool on the outer peripheral surface of the overlapping portion of the male mold or at least a part of the inner peripheral surface 15 of the partially overlapping portion of the male mold. According to this configuration, a region in which the male mold and the master mold are in sliding contact with each other is made smaller, so that frictional heat generation can be prevented due to a reduction in the friction surface of the mold. In particular, when at least a part of the lubricating liquid pool is formed at the surface of the peripheral surface 20 except for the partially overlapping portions where the male mold and the female mold partially overlap each other, the mold and the metal plate (material to be processed) are in sliding contact with each other. The area is made smaller, so that the generation of frictional heat can be further prevented. Further, if a lubricating liquid having water as a base is used as the lubricating liquid, since the specific heat of the lubricating liquid in which the water is the base is high, the mold can be efficiently cooled. 10 1313197 Further, according to the present invention, the outer-small-small-diameter portion having an outer diameter smaller than the front end portion of the male mold is formed on the outer surface of the partial overlap portion of the male mold as the aforementioned lubricating liquid pool, which may be alternately The large-diameter portion having a diameter larger than the inner diameter of the open end edge of the female mold is formed as the aforementioned lubricating liquid pool on the inner peripheral surface of the overlapping portion of the portion 5 of the female mold. According to the structure, the small diameter portion or the straight portion The portion can be made by cutting in the manufacturing process, and by simple processing, a lubricating liquid pool having rain lubrication ability and high cooling effect can be provided in the fixture. Further, according to the present invention, for supply The lubricating liquid path to the lubricating liquid pool 1〇 is disposed in the male mold or the master mold. According to the structure, the lubricating liquid flows through the lubricating liquid path, and the lubricating liquid can be reliably and efficiently supplied to the lubricating liquid. Lubricate the liquid pool. If the lubrication liquid path is formed from the base portion to the inside of the male mold, the squat is at the peripheral surface other than the portion overlapping the male mold. The lubricating liquid pool and the lubricating liquid in the 15-way/闰/month liquid pool flow through the inside of the male mold, so that the lubricating liquid can be more reliably and efficiently supplied to the peripheral surface outside the partially overlapped portion of the male mold. Therefore, according to the present invention, the lubricating liquid path includes an axial path formed from a base portion of the male mold along an axial direction, and a branch 2 〇 path is connected to the axial path and tied thereto Extending one side of the radial assembly including one of the male molds; and a diverging wall for redirecting the flow of the lubricating liquid from the axial direction of the male mold to the direction including the radial assembly, which is disposed in the axial path and the branch path cross According to the structure, the lubricating fluid system flowing through the axial path collides with a wall of the divergence 1313197 and thus flows to a branch path. Therefore, the lubricating fluid is further reliably and efficiently supplied into place. a pool of lubricating liquid at a peripheral surface outside a portion of the overlap of the male mold. Further, according to the present invention, at least 5 of the peripheral edges of one of the lubricating liquid pools The part is dehorned. According to this configuration, the lubricating liquid from the lubricating liquid pool is directed downward toward the front end portion and the open end of the mold having the greatest load and requiring the most lubrication as a part in contact with the metal plate such as an aluminum plate. The portion partially flows, and thus the lubricating liquid is easily supplied to the end portion of the mold and the end portion of the opening 10. Therefore, the lubricating ability and the cooling ability associated with the mold are further improved, so that heat generation of the mold can be prevented. Further, according to the present invention The lubricating liquid pool is formed by a portion of the lubricating liquid pool that is partially shorter than the front end portion of the male mold or the open end edge of the female mold. 15 According to this structure, the lubricating liquid pool Partially approaching the front end portion and the open end portion of the mold having the maximum load, so that the lubricating liquid in the lubricating liquid pool easily flows to the front end portion of the male mold and the open end portion of the female mold at the portions . On the other hand, at the position other than the end portion of the male mold and the open end portion of the female mold, the strength required for cutting and piercing the 20 metal plate such as an aluminum plate can be ensured. Therefore, it is possible to effectively lubricate the front end portion of the male mold and the open end portion of the master mold while maintaining the strength required for the mold processing. At this time, if water or a lubricating liquid having water-soluble lubricant dissolved in water is used as the lubricating liquid as the lubricating liquid, it is possible to realize the coexistence of the production of 12 A^13l97 and the natural if. Reducing manufacturing costs, processing and summer work/4_ garment production lines can be simple and miniaturized. Furthermore, when the hole is formed by using the above-mentioned press working die on a plurality of times, the press working method of the present invention may include an alpha lubricating fluid (4) of the lubricating secret pool. In the &mold and the phase of the MS's MS to its second position, the one/interval of the state is when the male and female molds cooperate with each other and the towel at least temporarily stores the lubricating liquid. The liquid pool is completely or partially formed on the outer peripheral surface of the partially overlapping portion of the partial (4) male mold or the inner peripheral surface of the overlap portion 10 of the female mold. Therefore, it is possible to supply the lubricating liquid to the lubricating liquid pool for each-pressing cycle, and at least temporarily store the lubricating liquid in the lubricating liquid pool for each press cycle, thereby improving when the male mold and the master mold are matched with each other. The lubrication and cooling efficiency at the partially overlapping portions of the male and female molds partially overlapping each other. According to the die for processing of the present invention, the smoothing liquid is supplied to the mold which is required to be sufficiently lubricated by the muddy liquid pool in the male or female mold, and the front end portion 'and the lubricating effect can be improved. Furthermore, by arranging the lubricating liquid pool, the area of the friction portion of the mold can be made small. Therefore, even when water and water are used as the base of the turbid liquid or the like in the press working, it is possible to prevent heat generation due to the friction of the mold, and even if water and water are used as the base in the process of processing When a sliding liquid or the like is used instead of the press working oil, it is also possible to provide a mold for processing that is sufficient for practical use. 13 1313197 Further, according to the press working method of the present invention, since the male mold and the master mold are fitted to each other when the lubricating liquid is stored in the lubricating liquid pool, the male mold and the female mold partially overlap each other. Lubrication and cooling efficiency at partially overlapping portions. Therefore, even when a water-based lubricant having a low running ability is used, it is possible to prevent a disadvantage such as mold heat or the like due to friction, and provide a press working method sufficient for practical use. At this time, according to the die for press working of the present invention, it is expected to use a conventional hydrocarbon even when water having a low lubricating ability as a lubricating liquid of the base 10 is used as the lubricant of the hydrocarbon-based base. The base oil can extend the life of the mold.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the specific embodiments of the present invention will be described with reference to the drawings. It should be noted that the invention is not limited to the specific embodiments. 1313197 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Fig. 1A is a partially enlarged longitudinal sectional view showing a first embodiment of the press working of the present invention, which is applied to a perforation and a reaming. In the molds shown in Figs. 1A to C, a perforating punch 1 as a male mold is separately used for perforating in a metal plate for making the hole conspicuous, and as an expansion of a female mold. Hole punch 2. The punch punch 1 and the counter punch 2 are respectively made of cemented carbide. The punching punch 1 is configured as an upper die 5 and a die button 3' for the same reaming, and the perforating punch 1 is arranged around the punching punch 2, and the reaming punch 2 is configured as The lower mold 6 is connected to the reaming punch 2 with the same stripper plate 4'. The punching punch 1 and the reaming punch 2 are formed on the metal plate disposed therebetween by a shear force to form a hole ', and after forming the hole, the punching punch i is fitted in the reaming punch 2, Therefore, the punching punch 1 and the counterboring punch 2 cooperate with each other. The lubricating fluid pool 10 is disposed on an outer peripheral surface 13 15 of one of the punching punches 1. According to this embodiment, in the case of the lubricating fluid pool 10, a small diameter portion is formed which has a diameter smaller than an outer diameter at a front end portion 15 of the perforating punch 1. 1B is an enlarged view of a range of the partially overlapping portions 13a and 24a, wherein when the punching punch 1 and the reaming punch 2 are fitted to each other, the peripheral surface of the punching punch 1 and the reaming punch 2 The inner peripheral surfaces overlap each other by 20 points. As shown in Fig. 1-8, the lubricating liquid pool 1 of the punching punch 1 is disposed on the outer peripheral surface of the partial overlapping portion 13a of the punching punch 1. In the present embodiment, the small diameter portion of the lubricating liquid pool 1 is configured to be separated from the front end edge 15a of the punch punch 1 by a length in order to ensure that the perforating operation is performed thereon. A relatively large load is applied to the front end portion 15 of the 16 1313197 hole punch 1 with sufficient strength. The perforating punch 1 has a lubricating fluid path 31 in communication with the lubricating fluid pool 10. As shown in the drawing, the lubricating liquid path 31 is constituted by a base portion 17 of a punching punch to the inside of the punching punch for lubricating liquid which is formed on the outer peripheral surface of the 5-part overlapping portion 13a. Pool 10 is connected. The lubricating liquid path 31 of the present embodiment is an axial path 33 formed from a base portion 17 along an axial direction, and is in communication with the axial path 33 and along a radius of the punch punch 1 The directionally elongated branch path 35 is configured. At this time, the present embodiment is not limited to this structure, and the lubricating liquid path 31 can be constituted by an axial path 33 formed on the punching punch 1 as a male mold, and a branching path (not shown) thereof It is formed by an axial path 33 which is inverted Y in a longitudinal portion and is elongated in a direction including a radial direction, and the sputum communicates with the lubricating fluid pool 10. According to the present embodiment, the lubricating liquid path 31 is disposed inside the punching punch 1 as a male mold. However, if the lubricating fluid can be supplied to the lubricating fluid pool 10, the lubricating fluid path 31 can be disposed in either of the male mold and the female mold. Further, the lubricating liquid path 31 may be disposed inside the mold or outside the mold. Furthermore, according to the present embodiment, the two branch paths 35 20 are arranged in the radial direction, however, if the strength at the front end portion 15 can be sufficiently ensured, an appropriate number of branch paths 35 can be provided, for example, four Or a six-branch path. As is apparent from Fig. 1A, in the branch path 35 of the present embodiment, one of the portions is opened at the smaller diameter portion 1313197 where the lubricating fluid pool 10 is configured, and the other portion is tied to the perforation. At a position where the front end edge 15a of the head 1 is close, it is opened on the peripheral surface other than the punching punch. Therefore, one of the opening portions 35 5 of the branch path 35 is made to be a part of the lubricating liquid pool, and therefore, at the opening portion 35a of the branch path 35, the end portion of the lubrication night 5 body pool 10 and the punch punch 1 is A distance between the edges 15a is partially short, and the lubricating liquid pool 10 is constructed in this manner. At this time, when the lubricating liquid pool 1 is provided in the master mold, the lubricating liquid pool 10 can be constructed so that the distance between the lubricating liquid pool 10 and the end edge of the master mold is partially made short. Further, a 'difference wall 37 is disposed at a portion of the perforating punch 1 where the axial path 33 intersects the branch path 35 (the branch portion 35 branches from the axial path 33). At this time, according to the present embodiment, the branch wall 37 is formed by making the axial path 33 located on the front end side of the punching punch 1 narrower than the intersection portion with the branch path 35, however, the divided wall is formed. 15 37 such that the axial path 33 terminates at the dividing wall 37. Here, an example of the size of the punch punch 1 as a reference will be described with reference to Fig. 1C. In this example, a diameter d of the front end portion of the punch punch 1 is 4·8 mm, and a length from the front end edge to the small diameter portion in an axial direction is 2 mm. In the small 20-diameter portion as the lubricating fluid pool 10, the axial length h is 3.5 mm, and the depth of a recess from the peripheral surface other than the partially overlapping portion is 0.2 mm (in FIG. 1C) f) 'and one of the recesses has a diameter (outer diameter) s of 4.4 mm. Therefore, in this example, the volume of the lubricating liquid pool 1 is about 10.11 mm3, and the lubricating liquid can be stored in the lubricating liquid pool 10 according to this volume. Further, in relation to the 1313197 muddy liquid path 31, the diameter of the axial path 33, the diameter from the base portion 17 to the branch wall 37 is i = 2 mm, and the front end portion of the punch punch is exclusive The diameter is e = 1 mm. Furthermore, the diameter j of the branch path ^ is 1.5 mm. 5 (4) The reaming punch 2 of the master mold is opened, and the inner diameter thereof is slightly larger than the outer diameter of the front end portion 15 of the perforation punch, and has a receiving hole to receive the end portion before the punching. Receiving the inner surface sand of one of the holes 28, and the inner surface of the portion 24a of the knives, when the punching punch 1 is engaged with the reaming punch 2, the portion overlapping the portion of the punching punch 1 is l3a The outer peripheral surface of the outer portion 10 is partially overlapped and slidably contacted. Further, the inner surface of the two stepped portions and the partial overlap portion 24a of the 45-series self-joining hole 28 are disposed downward, so that the downward inner diameter is large and when the perforating punch 1 is formed into a hole in the metal plate The resulting metal component is easily dropped from the reaming punch 2. 15 will be explained in the example of the punching and reaming die shown in Figs. 1A to 1C. In this example, the lower direction in the figure according to the present embodiment is the one inserted into the punching punch 1. The direction, and an upward direction, are a direction in which the punch punch 1 is pulled out. A metal plate such as a lubricant-coated aluminum 20 plate or the like which is one of the materials of the I, the I, is mounted on the stripper, and then the upper die 5 is dropped. The front end edge l5a of the punch punch i is in contact with the metal plate, after which the metal plate is placed between the round punch and the stripper plate 4. The perforating punch is further advanced and the metal plate is shear-cut to form a hole when the end portion 15 of the perforating punch i is engaged with the receiving hole 28 of the reaming punch 2. 1313197 After the hole is formed, the reaming punch 2 also moves upward as the punching punch 1 moves upward. Due to this upward movement, the peripheral edge of the hole constituting the metal plate is pushed up by a push-up portion 42 disposed at a front end portion of the reaming punch 2, and is pressed by the push-up portion 42 and the circle One of the reaming holes 5 of the head 3 receives the portion 46 to complete the reaming operation. Thereafter, the upper mold 5 is moved upward, and the reaming punch 2 is moved downward. The perforated and reamed metal sheet is removed from the reaming punch 2 by the stripper plate 4, thereby completing the perforating and reaming steps. Next, with reference to Figures 2 and 3, the influence of the lubricating fluid pool 10 at the time of perforation will be described below. Fig. 2 is a view showing a state in which the perforation 1 and the reaming punch 2 are matched in the die 1 of the press working die in Fig. 1, and the blade is opened as shown in Fig. 3. status. The lubricating fluid is supplied from a tank (not shown) to the mold via a tube fitting by a pressure supply means (not shown) such as a gear pump or the like. The supplied lubricating liquid flows from the perforating punch k base portion 17 downward through the axial path %, and the liquid partially redirects to the branch path 35 which communicates with the lubricating fluid pool 10 by the 15 diverging wall 37. Preferably, the 'slip liquid is supplied to the lubricating liquid pool 10, so that the rotting liquid does not contain as much gas as possible' because if it is supplied to the lubricating liquid pool, it is a lubricating liquid that does not contain gas', for example, with the supplied lubrication. The liquid system is higher in cooling capacity than in the case of a spray. 2. When the molds are separated as shown in Fig. 3, the wetting/J?/night system supplied to the lubricating fluid - also 10 is along the outer peripheral surface of the partially overlapping portion 13a of the punch punch The flow ' is used to lubricate the front end portion 15. When the molds such as shai cooperate with each other, the inner peripheral surface of the partially overlapped portion 2 of the reaming punch 2 is in contact with the lubricating liquid 1131197 stored in the lubricating liquid pool 1G, and the lubricating liquid is partially overlapped in the punching punch 1. The outer peripheral surface of the 13a flows between the inner peripheral surface of the partially overlapping portion 24a of the counterbore punch 2, and the partially overlapping portions of the punching punch 1 and the counterboring punch 2 are respectively lubricated.
此外，假若因應搪孔之時程以高壓將潤滑液體供給至 5 模具，則剪切金屬板時所產生的粉末係藉由由壓力進給之 潤滑液體自介於該穿孔衝頭1及擴孔衝頭2之間推離。因 而，防止切削粉末黏附至在作為公模的穿孔衝頭1與作為母 模的擴孔衝頭2之間嚙合的模具上，並且如此可避免產生發 熱。 10 如以上所述，本具體實施例之分支路徑35係於接近穿 孔衝頭1之則端部邊緣15a處開啟，而非作為潤滑液體池1〇 的小直徑部分處。易言之，潤滑液體池1〇係如此構成以至 於在分支路控35之開π部分35a處介於潤滑液體池1〇與穿 孔衝頭1之前端部邊緣…之間的-段距離係部分地為短 15的k而，見骨液體易於流至前端部邊緣…，而非流至在 開口 4刀35a處製成較小直徑部分的騎液體池a之該部In addition, if the lubricating liquid is supplied to the 5 mold at a high pressure in response to the time course of the boring, the powder generated when the metal sheet is sheared is self-interposed between the punching punch 1 and the reaming by the lubricating liquid fed by the pressure. Push between the punches 2. Therefore, the cutting powder is prevented from adhering to the mold which is engaged between the punch punch 1 as the male mold and the counterboring punch 2 as the master mold, and heat generation can be prevented in this way. As described above, the branch path 35 of the present embodiment is opened near the end edge 15a of the perforating punch 1, not as a small diameter portion of the lubricating liquid pool 1〇. In other words, the lubricating fluid pool 1 is configured such that the portion of the distance between the lubricating liquid pool 1 and the end edge of the punching punch 1 is at the open portion π portion 35a of the branch path 35. The ground is a short k of k, and it is seen that the bone liquid is easy to flow to the edge of the front end ... instead of flowing to the portion of the liquid pool a which is made of a smaller diameter portion at the opening 4 knife 35a

The specific heat of the liquid is higher than that of the oil-based body, and the cooling effect is higher. The position of the upper end portion of the smaller diameter portion of the lubricating fluid pool 10 is squatted. Contact with the metal plate as the processing body, because contact with the metal plate can cause unnecessary and harmful powder. 10 15 In addition, as clearly shown in Fig. 2, I can punch the punch! The front end portion 15 is slidably and reamed. The inner peripheral surface of the partially overlapping portion (4) of the head 2 is in contact, however, since the lubricating liquid pool H) is concave with respect to the outer peripheral surface, the lubricating liquid pool is not in contact with the inner peripheral surface of the partially overlapping portion 24a. In other words, the friction area between the male mold and the female mold is reduced, and the excessive friction is reduced, so that the frictional heat can be prevented.

Therefore, irreparable damage is not caused in the mold, and only micro-friction occurs in the front end portions of the male mold and the female mold. This friction with the metal mold is not inferior to the example of using a hydrocarbon-based lubricating oil as a press working oil. Figures 4A and 4B show SEM photographs of the mold after 100,000 shots in the punching operation. Here, the maps 4A and 4B correspond to the graphs 3a and 13B, respectively. With respect to the conventional mold shown in Fig. 13, comparing these SEM photographs, it can be understood that the lubricating ability is highly improved.

In the case of intermittently supplying a lubricating liquid, it is possible to adjust the supply of the lubricating liquid by moving a rotating cam and a coded cymbal or the like. 5 For example, if the top dead center (Upper is centered) is 0 degrees, the lubricating fluid can be adjusted at a rotation position from 170 degrees to 185 degrees including the next dead point (i8 twist). - Straight to the mold (lubricating liquid pool). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 2 Next, another specific embodiment of the present invention which is different from the above-described specific embodiment will be described with reference to FIG. Fig. 5 is a partially enlarged longitudinal sectional view showing a second embodiment of the press working die of the present invention applied to the punching and reaming mold device. This press working die is different from the press die for the first embodiment. The only difference is 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 reaming. On the inner surface of the punch. Therefore, the same representative symbols are the same elements in the i-th and fifth figures, and a detailed description thereof will be omitted herein. Referring to Fig. 5, the lubricating fluid pool 10 is formed on the peripheral surface 24 of the reaming punch 2. The lubricating fluid pool 10 is constructed by providing a large diameter portion having an inner diameter larger than the end edge 26a of the counterbore punch 2 on the inner peripheral surface of the portion of the overlapping portion 24a of the counterbore punch 2. On the other hand, the punch punch 1 shown in Fig. 5 has the outer diameter from the lower edge of the base portion 17 of the punch punch 1 to the front end edge 15a which is the same as the outer diameter of the front end 23 1313197 edge 15a. Inside the punch punch, a lubricating liquid path 31 made up of the axial path 33 and the branch path 35 is formed. At a portion of the axial path 33 and the intersection of the branch light 35, a partition wall 37 is disposed for redirecting a portion of the lubricating fluid to a diametrical direction. 5 In the socket punch 1, the full slip liquid collides with the branch wall 37 via the axial path 33 and flows out from the opening portion 35a of the outer peripheral surface 13 of the punching punch of the branch path 35. Therefore, when the punching punch and the reaming punch 2 are engaged with each other, the lubricating fluid system flowing from the branching path light 35 is supplied to the lubricating liquid pool 10 of the counterboring punch 2, and temporarily stored therein. In this case, if the surface of the body 10 of the lubricating fluid 10 is processed to be rougher than the other surface of the counterbore punch 2, the lubricating liquid can be more preferably held by the surface tension of the lubricating liquid. Further, when the punching punch 1 moves into and out of the receiving hole 28 of the counterboring punch 2, the lubricating liquid flowing from the opening portion 35a can lubricate the outer peripheral surface of the partially overlapping portion 13a of the punching punch i, and the reaming punch Part 2 overlaps the inner surface of the inner portion 15 of the 24& Therefore, in the die for press working of the second embodiment, the mold can be sufficiently lubricated and the portion to be lubricated by the processed material can be received. Further, the inner peripheral surface of the partially overlapping portion 24a of the counterbore punch 2 is brought into contact with the peripheral surface of the portion overlapping the portion 13a of the punching punch 1, but 'because the lubricating liquid pool 10 is made by the large diameter portion The configuration is apparent as shown in Fig. 50, so that the inner peripheral surface of the partial overlapping portion 24a of the counterboring punch 2 is not in contact with the peripheral surface 13a other than the partially overlapping portion of the punching punch 1. Thereby, the area of the friction portion of the mold is made small, and the squeak prevents excessive friction. Specific Example 3 1313197 μ Further, a third embodiment of the present invention will be described with reference to Fig. 6. Figure 6 is a partially enlarged longitudinal cross-sectional view of the vicinity of the end portion of the dental prosthetic punch, with the de-angular lower edge as in the first embodiment of the present invention - the embodiment of the mold cap for compression processing A small diameter portion of the pool of lubricated liquid. The perforation punch differs from the above-described first embodiment only in that the lower side of the small diameter portion constituting the lubricating liquid pool 1 () is chamfered. Therefore, the same reference numerals are used for the same elements in the first and sixth figures, and the detailed description thereof is omitted here. 10 15 In relation to Fig. 6, the _ angling portion having the arc portion is disposed, and the perforating punch H slides the liquid pool _ the lower edge of the small diameter portion so that Ik is supplied by the lake sliding liquid path 31 The lubricating liquid pool _ lubricating liquid is easily flowed downward by the chamfered portion 51, so that the front end portion 15 is easily subjected to lubrication.

With reference to Fig. 8, a lubricating liquid passage 15 diameter 62 is disposed inside the stripper plate 4 as an injection path, and the lubricating liquid can be sprayed toward the lubricating liquid pool 10 of the punching punch 1. The lubricating liquid path 62 is extended in an oblique direction from a portion above a surface 64 of the counterboring punch 2 facing the stripper plate 4 to the base portion of the stripper plate 4. In the die for press working shown in Fig. 8, the lubricating liquid sprayed from the lubricating liquid path 62 in an appropriate time course is lubricated to lubricate the front end portion 15 of the punch punch, and further, the lubricating fluid system temporarily It is stored in the lubricating fluid pool 1' so that the lubricating liquid required for the press working can be sufficiently maintained. Fig. 9 is an example of a die for press working in which a lubricating liquid path 61 is tied in the circular punch 3. According to Fig. 9, the lubricating liquid path 61 27 1313197 is elongated 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 counterbore receiving portion 46 is then dispersed to the lubricating liquid pool 10, the front end portion 15 of the punching punch 1, or the front end portion 5 of the counterboring punch 2, which lubricates the portions. Further, by storing the lubricating liquid in the lubricating fluid pool 10, the lubricating liquid required for the press working is ensured. Fig. 10 is an example of a die for press working in which a lubricating liquid path 72 is disposed inside a counterboring punch 2 as a master. In Fig. 10, the lubricating fluid pool 10 is disposed in a master mold, and the lubricating fluid path 72 is elongated to communicate with the lubricating fluid pool 10 from the base portion of the reaming punch 2. Thereby, the lubricating liquid can be directly supplied to the lubricating fluid pool 10. At this time, the lubricating liquid pool 10 is disposed in the punching punch 1 as the male mold, and the lubricating liquid path 72 is disposed in the counterbore punch 2 as the master mold, and the lubricating liquid path 72 is formed to partially overlap. The peripheral surface of the inner portion 15a is elongated and opened at the inner peripheral surface of the partially overlapping portion 24a. Therefore, the peripheral surface inside the reaming punch is sufficiently lubricated, and further, when the punching punch 1 and the counterboring punch 2 are engaged with each other, the lubricating liquid is supplied to the lubricating liquid pool 10 of the punching punch 1. Further, the lubricating liquid can be supplied from the lubricating liquid path 20 72 to the lubricating liquid pool 10 of the punching punch 1. The lubricating liquid supplied to the lubricating liquid pool 10 is stored there by the injection of the lubricating liquid, and at the same time, the lubricating liquid can be supplied to the front end portion of the punching punch 1. According to the examples shown in Figures 8 and 9, the lubricating fluid pool 10 is disposed in the punching punch 1 of the 1313197 10 15 20 as a male mold, however, the lubricating fluid pool is formed in the master mold' configurable 8th and In the figure 9 - Mu does not lubricate the liquid path. In addition, according to the actual figures shown in Figs. 8, 9, and 10, the lubricating liquid path, iron & ..., can be used simultaneously in the punching punch 1 which is not a male mold. The lubricating fluid path shown in 8, 9 : and the lubricating fluid path configured as the 7 head 1 . Furthermore, the different punching punches 1 shown in Fig. 7 can also be constructed as "1" for the piercing punches shown in the figures 8, 9, and 10, which are now used in the slidable liquid pool. In the case of a lubricating liquid 俾仏# s~, 'α device of a lubricating liquid, for example, there is a pressure-feeding device such as a gear pump or the like (in the first to fifth embodiments described above) Not shown).兮 Edge-lubricating liquid supply device can be properly configured inside a press, and the 戋% 绕% is used in the components of the press. Further, according to the above-described (four) embodiment, only a mold such as a wear, punch or a similar 7L piece is made of cemented carbide. It can be used to include a hard carbide such as a slightly tertiary 'superhard alloy such as tungsten carbide (WC) and titanium carbide (Tic) or the like, and „ and one such as cobalt (Co) and nickel ( A binder phase metal made of an iron group metal of Ni) or the like. Further, in the case of the water-soluble lubricant, an organophosphorus compound and an organic metal salt may be used. The water-based lubricating fluid may comprise a metal active inhibitor to prevent the binding phase metal of the U, y, and s5 compounds from dissolving in the lubricating liquid, and the rabbit eight M w 4 Because the metal active inhibitor can prevent the corrosion of the cemented carbide due to the dissolution of the binder phase metal.
