200536630 九、發明說明： L發明戶斤屬之技術領域3 發明領域 本發明有關於一種金屬壓模構件及金屬衝壓加工的方 5 法，其用以衝壓加工，例如塑膠加工或金屬片的衝壓工作， '更詳言之係有關於一種金屬壓模構件，其用以製造熱交換 器的熱交換鰭片，例如可包含於空氣調節器中，及用以使 用此壓模構件之金屬衝壓加工的方法。 • 【先前技術】 10 發明背景 習知使用於車用、家用等的空氣調節器中熱交換器的 熱交換籍片是藉由一組衝壓加工方法來製造，如第7 A圖所 示。此種衝壓加工方法主要包含一預成形製程，以可輕易 對待加工的金屬板，例如I呂板加工、一穿孔與衝緣(拉伸衝 15 緣）製程，以穿刺一孔於該預成形金屬板上且同時進行衝緣 加工、一熨壓製程，以自該金屬板上所形成的孔的周緣之 ® 凸出部形成一軸環，及一再外擴(reflaring)製程，以彎折成 形的軸環之尖端。藉對金屬板例如紹板來進行此衝壓加工 ‘ 方法，即可製造如第7B圖所示之板狀鰭片。 20 當進行此衝壓加工時通常會使用潤滑流體來防止模具 的磨損及防止例如待加工的材料（金屬板）的磨損之問題 發生。 現在是使用碳氫化合物潤滑油以於製造熱交換器的熱 交換鰭片的衝壓加工期間作潤滑之用。與目前已使用的無 5 200536630 機油式的潤滑油不同，碳氫化合物潤滑油無須使用氣化有 機〉谷劑清洗’因此在被認為疋地球環境保護(earth-conscious) 的潤滑油之下廣泛使用此碳氫化合物潤滑油。 當使用碳氫化合物潤滑油進行衝壓加工時，基於鰭片 5 的製造效率，該等鰭片在將黏著於該等鰭片上的潤滑油蒸 發工作且乾燥該等鰭片之後加熱。為防止被蒸發的碳氫化 合物排出於外部空氣内，會使用一觸媒燃燒處理。至於在 以液態使用於衝壓加工之後自壓模所聚集的碳氫化合物潤 滑油，其特別以工業廢棄物處置。以此方式，當使用碳氫 10 化合物潤滑油時，後處理工作（aftertreatments)例如觸媒燃 燒及碳氫化合物潤滑油成工業廢棄物的處置需要龐大的成 本。並且對於現今高漲的全球環境保護活動，使用更為地 球環境保護的潤滑劑曰益必要。 另一方面，為取代碳氫化合物潤滑油的使用，技術發 15 展向使用水或似水的潤滑流體作切割工作。後者為水溶 液，其含有水溶性潤滑劑溶解於水中。若可使用水潤滑流 體（之後，此名詞”水潤滑流體”亦包含水）來作衝壓加工 時的潤滑，則將不僅可解決後處理工作例如觸媒燃燒及成 工業廢棄物的碳氮化合物潤滑油的處置之問題及節省其成 20 本，並且可基於自然環境的保護實現更為環保的製造方 式。隨之，亦可達到縮減製造裝置及生產線的功效，且可 達到對起始投資成本及運轉成本之大量降低的功效。 然而，金屬壓模構件包含有模穴部以納置彈性元件， 例如彈簧，用以上下移動刮除板或脫模銷(knockout pin)。 6 200536630 且^用水潤滑流體作為潤滑劑時，此水潤滑流體將會流 卩及池内。由於此潤滑流體含有濕氣，因 Z常彈*婦製成的彈簧生敍因线部經妓覆^ 造成彈性疲乏失致的問題。 復負载 — N'兄已使用以樹脂包覆的彈簣，但對增長 =Γ=:僅造成的些許的助益。且在以包覆材料因

仃後處理玉作，例如於衝壓加卫之後需清洗產品。 β因此本發明的發明人考慮到，當使用水潤滑流體來衝 1加工時，而要提供可將潤滑流體自用於納置彈性構件或 裝置的模穴部排出的裝置手段，用以防止該潤滑流體流入 該等模穴部内，其設置於金屬壓模構件例如衝壓板處。 至於將不要的材料，如落入模具的模穴部内的潤滑流 體排出之裝置，日本專利公開公告號碼09436133(1997)揭 不一種技術，設置穿孔於一鍛造模具的主體的模穴底表面 上，以作為當進行鍛造時潤滑流體殘留物之排出孔。另一 方面，如申請人及發明人所認知，尚無習知技藝是有關於 防止潤滑流體流入於金屬壓模的模穴部之技術。 7 200536630 儘管曰本專利公開公告號碼09-136133(1997)所揭示的 技術是有關於將不需要的潤滑流體殘留物自一模穴内部排 出，而待加工物件直接插設於此模穴内以加工，本發明與 此不同處係在於其目的是將已流入模六部内的潤滑流體排 5 出或是防止潤滑流體流入於該等模穴部内，而刮除板或脫 模銷(knockout pin)的動作所必要之彈性構件是納置於該等 模穴部内。此外，如日本專利公開公告號碼09-136133(1997) 所揭示的技術並不以使用水潤滑流體為前提。因此，如日 本專利公開公告號碼09-136133(1997)所揭示的技術並未解 10 決使用水 >閏滑流體所伴隨之問題。據此，於如日本專利公 開公告號碼09-136133(1997)所揭示的技術中（見日本專利 公開公告號碼09-136133(1997)，[0017]段落，第1及2圖）， 認為無須將已流入模穴部内的潤滑流體排出或是防止潤滑 流體流入於該等模穴部内，而刮除板或脫模銷的動作所必 15要之彈性構件是納置於該等模穴部内。相比之下，本發明 是以使用此水潤滑流體為前提。 C發明内容】 發明概要 有鑑於以上所述，本發明的目的在於提供一種金屬壓 20模構件，可防止彈性構件如彈簧的壞蝕，及藉由防止當使 用水潤滑流體進行衝壓加工時不必要的潤滑流體停在:具 上來防止該等模具上的流體之壞姓。 為達到此目的，本發明的壓模構件的一實施例之主要 元件疋提供一排出路徑，用以排出流入於供彈性構件至少 8 200536630 一部分納置的模穴部内之水潤滑流體，至該等模穴部外側。 以此配置，即使加工使用的水潤滑流體已流入於形成 在該金屬壓模構件上的模穴部内時，該潤滑流體可經由該 排出路徑排出於該等模穴部外側。因此，不會有水潤滑流 5體累積於該壓模構件的模穴部内，且可防止壓模構件或彈 性構件壞钱且可防止因殘留水潤滑流體而造成細菌增殖。 根據本發明一實施例，其亦宜將該排出路徑設置於一 阻礙構件上，於該模穴部是包含貫穿構成該壓模構件的一 構件之一穿孔的内表面，及至少一部分插入於該穿孔内之 1〇 該阻礙構件的頂面。 以此配置’將可相當輕易地將該排出路徑裝上於該壓 模構件及自其分開。並且相較於該排出路徑是形成於該模 具的其他部分之例，將可相當輕易地形成該排出路徑於該 阻礙構件上，此係因相較於該模具的其他部分（衝壓板或 15類似物），該阻礙構件相當小。 進一步地，本發明的壓模構件不同於上述實施例的其 他實施例的其中之一主要元件在於設置防止流入裝置，用 以貫質上防止水潤滑流體流入於該模穴部内，其内是供該 彈丨生構件的至少一部分納置而容許該彈性構件的擴張與收 20 縮。 以此配置，實質上水潤滑流體不會流入於形成在該壓 杈構件上的模穴部内。據此，無水潤滑流體灘留於該模具 構件的模穴部内，因此將可解決該模具與彈性構件的壞蝕 問遞以及因水潤滑流體產生的細菌增殖問題。 9 200536630 根據本發明的金屬壓模構件，其設置一排出路彳①以 开>成於孩專模具構件如衝壓板上用以納置彈性構件至小 部分的杈穴部排出潤滑流體，以致於潤滑流體可經由兮〜 排出路徑自該等模穴部排出，藉此可防止該等模具構件 1 5納置於該等模穴部内的彈性構件如彈簧之壞蝕。此外，三 於水潤滑流體將難以累積於該等模穴部内，因此即可= 該等模穴部内細菌的孳生。因潤滑流體的壞姓所導致 味亦可解決。 ~ 於該排出路徑設置於阻礙構件如塞體上的狀況是包括 H)該等模穴部的底部以納置該等彈性構件，該排出二二 易地裝上於該模具構件且自其移離。由於該排出路徑是設 置於阻礙構件上，其相較於其他模具構件（例如衝壓板或 類似物）具有相當小的尺寸，該排出路徑相較於將排出路 控設置在其他模具構件上，可以相當輕易的方式來設置。 15進一步地’於設置有該防止流入裝置以實質上防止水 潤赫體流入至納置該等彈性構件之該等模穴部的狀況， 可實質上防止水潤滑流體流入至該等模穴部。據此即可解 決納置於該等模穴部内的彈性構件的壞餘之問題，及因該 等模穴部中潤滑流體壞麟造成的異味之問題。 20 圖式簡單說明 ° 兹將本發明的實施例以舉例方式並配合參考圖式詳細 說明，其中： 第1圖是顯示應用本發明的金屬壓模構件（實施例1} 的一部分之部分剖視圖； 200536630

程及一穿孔與衝緣製程，直到其到達一熨壓製程。 熱交換鰭片用之本金屬壓模構件是包括一上鑄模及一 下印模以可開放與可封閉方式設置，且一熨壓用印模（未 11 200536630 圖示）及其餘物被保持於一包含該上禱模的印模板（未圖 示）處。 另-方面’該熨壓衝頭2固定於_包含該下印模的衝壓 板1處。一刮除板3設置於該衝壓板丨上方遠離該板丨一預定 5距離。該刮除板3是以彈簧（捲繞彈簧）5彈性支撐，該等 彈簧作為彈性構件。該刮除板3被打孔以界定一穿孔％，該 熨壓衝頭2的尖端部2a可穿過該穿孔3a，且該刮除板3的位 置可調整，以使當無負載施加於該刮除板3上時該熨壓衝頭 2的尖端部2a係低於該刮除板3的頂面。 10 用以彈性支撐該刮除板3的彈簧5的配置方式是將至少 一部分納置於形成在該下印模衝壓板丨上的模穴部6内且其 疋位於上。於弟1圖所示之實施例中，將該等彈簧$的下部 納置於該等模穴部6内。 於第1圖所示之實施例中，該等模穴部6包括形成於該 !5 下印模衝壓板1上的穿孔la之内表面及塞體（阻礙構件）7 的上表面，該等塞體7插設於該等穿孔1 a内且螺入這些穿孔 la内。穿孔穿設於該等塞體7的中心部處，其包括已流入於 該等模穴部6内的潤滑流體用之排出路徑8。 以此方式，當該排出路徑8設置於該塞體7處時，相較 2〇 於將該排出路徑8形成於該衝壓板1本身上，其具有較該塞 體7大的尺寸之例，該排出路徑8可相當輕易地形成，同於 其他實施例，將詳細說明於後。於此實施例中，儘管僅有 一排出路徑8設置於單一模穴部6内，然而亦可設置數個排 出路徑8於單一模穴部6上。進一步地，儘管於本實施例中 12 200536630 该排出路梭8是假設具有圓柱形狀，然而該排出路徑8的戴 面形狀並不侷限於圓形，而可假設為具有不同的形狀，且 該排出路徑8的形狀及/或橫截面亦可沿著縱向方向變化。 兹將詳細說明使用上述構造的金屬壓模構件並與水潤 滑流體共用來進行熱交換鰭片的衝壓加工之製程方法。 10 15 20 將已受穿孔與衝緣製程的一薄金屬板送到熱交換轉片 用之该金屬壓模構件的上鑄模（未圖示）與下印模（該熨 壓衝頭部分顯示）之間，且進行該上鱗模與下印模的閉模 工作。此時，當該上鑄模開始下降時，設置於該上鑄模上 的一下印模衝壓構件（未圖示）將會抵靠於已輸送至該刮 上的4金屬板11上，來衝壓制除板3向下而抗該等 彈彈力。然後該髮壓衝頭2已穿過該刮除板3的穿孔3a 之大端部再6伸於該刮除板3的頂面。該㈣朗2凸伸於 =除板3的頂面之尖端部插入於已在穿孔與衝緣製程中 全2成的—凸伸部lla内，如第1圖的虛線所示，且該薄 :。進反烫壓衝頭2藉使用該凸伸部ua進行相對定 被垂直向^推動上禱模的下降，該褽壓衝頭2會自已 經過二進行㈣部1—

致於邊管狀部能被可靠地從該印模拉出。該管狀部是藉由 5 一推出銷（未圖示）或一脫模銷（未圖示）從該印模推出。 當該管狀部已被鎖固於該熨壓衝頭2側時，該刮除板3 將藉該等彈簧5的彈力，其當該上鑄模上升時已解除壓縮 力，相對於該熨壓衝頭2相當地升高，以使該管狀部可自該 熨壓衝頭2的限制釋除。 10 在熨壓製程之後，該薄金屬板11 (已加工的材料）被 送至一再外擴(reflaring)製程，將—軸環的尖端向外彎折。 然後該薄金屬板11再切割成特定形狀以獲得一熱交換鰭 當該熱交換縛片經由上述方式的衝壓加工形成時，該 15專印模與待模製材料之間的潤滑作用對確保可使用性將很 重要。到目前為止是對此潤滑作用是使用含有易揮發碳氫 化合物成分的潤滑油。本發明的發明人提出使用水潤滑流 體來取代此種潤滑油以降低環境負擔。與使用碳氫化合物 的潤滑油不同，碳氫化合物的潤滑油是在加工之前完全施 20用於材料表面上（在該材料被送至該壓模構件之前），當使 用水潤滑流體時，其是視為將流體局部施加於所需位置的 方法疋宜用於避免形成於该薄金屬板包含有該材料的表面 上的潤滑覆層之洗提或脫落的目的，以使潤滑流體供應路 徑（未圖示）玎設置於該壓模構件内。 14 200536630 以此方式，當從設置於該等印模上該潤滑流體供應路 徑所供應的水潤滑流體進行該等印模及待加工材料的潤滑 s守，在潤滑之後留下的潤滑流體或過度供應的潤滑流體將 狀入於该下印模的模穴部。於本發明的金屬壓模構件中， 5該潤滑流體所流入於内之該等模穴部6形成有排出路徑8用 以排出潤滑流體，以致於已流入於該等模穴部6内的潤滑流 體將立即經由該等排出路徑8被排出。據此，已流入於該等 模穴部6内的水潤滑流體將難以留在該等模穴部6内。如此 將可防止潤滑流體因細菌增殖所產生的壞蝕。藉此，亦可 10 防止因潤滑流體的壞蝕所伴隨的異味之發生，且可降低清 洗熱交換鰭片以防止加工後產生異味之問題。 此外，由於已流入於該等模穴部6内的潤滑流體可從該 等模穴部6相當迅速地被排出，因此亦可抑制納置於該等模 穴部6内之該等彈簧5的壞姓。 15 有鑑於此，為了可更完整的方式來防止彈簧壞蝕，宜 使用彈簧5是以防水材質製成。可使用以樹脂材質例如氨基 钾酸酯所製成的圓柱形彈簧5、以防水不鏽鋼所製成的繞圈 形彈簧5，或施加防水覆層的彈簧5。 實施例2 20 第2圖是顯示不同於上述實施例1之實施例2。於實施例 2中，與第1圖所示的實施例1不同’將該等彈簧5納置於内 之該等模穴部6是形成為平底孔，其形成於該衝壓板1的頂 面上。用以排出該潤滑流體的排出路徑8是設置自該衝壓板 1的下表面向上穿過該衝壓板1至該等模穴部6，以致於與第 15 200536630 1圖所示的實施例1相似，已流入於該等模穴部6内的潤滑流 體可經由該等排出路徑8排出。由於其他配置皆與第1圖所 示的實施例1相同，因此相同構件將以相同參考標號表示並 省略其說明。 5 實施例3 第3圖是顯示不同於上述實施例之實施例3。於實施例3 中，供該等彈簧5納置之該等模穴部6是包含形成於該衝壓 板1上的穿孔之内表面及設置於該衝壓板丨底下的一背板13 之頂面。連通於該等模穴部6的排出路徑8是形成貫穿該背 10 板13，以致於可與上述實施例相似，已流入於該等模穴部6 内的潤滑流體可經由該等排出路徑8排出。由於其他配置皆 與上述實施例相同，因此相同構件將以相同參考標號表示 並省略其說明。 實施例4 15 第4圖是顯示不同於上述實施例之實施例4。於實施例4 中，該背板13不形成穿孔作為用以將已流入於該等模穴部6

Description of the invention: The technical field of the invention of the householder 3 Field of the invention The present invention relates to a method for metal stamping members and metal stamping processing, which is used for stamping processing, such as plastic processing or metal sheet stamping. , 'More specifically, it relates to a metal stamper member, which is used for manufacturing heat exchange fins of a heat exchanger, for example, may be included in an air conditioner, and a metal stamping process for using the stamper member. method. • [Prior Art] 10 Background of the Invention The heat exchange sheet of a heat exchanger used in air conditioners for automobiles, homes, etc. is conventionally manufactured by a set of stamping processing methods, as shown in FIG. 7A. This stamping method mainly includes a pre-forming process to easily process the metal sheet, such as I Luban processing, a perforation and punching edge (stretched punch 15 edge) process, to pierce a hole in the pre-shaped metal A blanking process and an ironing process are performed on the plate at the same time to form a collar from the protruding portion of the periphery of the hole formed on the metal plate, and a reflaring process is repeated to form the shaft. The tip of the ring. By performing this stamping process on a metal plate such as a plate, a plate-like fin as shown in FIG. 7B can be manufactured. 20 When this stamping is performed, a lubricating fluid is usually used to prevent mold wear and problems such as wear of the material to be processed (metal plate). Hydrocarbon lubricants are now used for lubrication during the stamping process of manufacturing heat exchange fins for heat exchangers. Unlike currently used oil-free lubricants of 200536630, hydrocarbon lubricants do not need to be gasified organic> cereal cleaning ', so they are widely used under earth-conscious lubricants This hydrocarbon lubricant. When a hydrocarbon lubricating oil is used for stamping, based on the manufacturing efficiency of the fins 5, the fins are heated after the lubricating oil adhered to the fins is evaporated and the fins are dried. To prevent the evaporated hydrocarbons from being discharged into the outside air, a catalytic combustion process is used. As for the hydrocarbon lubricant accumulated from the stamper after being used in the liquid state for the stamping process, it is particularly disposed of as industrial waste. In this way, when hydrocarbon 10 lubricants are used, aftertreatments such as catalyst combustion and the disposal of hydrocarbon lubricants into industrial waste require significant costs. And for today's rising global environmental protection activities, it is necessary to use more environmentally friendly lubricants. On the other hand, in order to replace the use of hydrocarbon lubricating oils, technology has been developed to use water or water-like lubricating fluids for cutting. The latter is an aqueous solution which contains a water-soluble lubricant dissolved in water. If a water-lubricating fluid (hereinafter, the term "water-lubricating fluid" also includes water) can be used for lubrication in the stamping process, it will not only solve post-processing tasks such as catalyst combustion and carbon waste lubrication as industrial waste. The problem of oil disposal and the cost savings are 20, and a more environmentally friendly manufacturing method can be realized based on the protection of the natural environment. As a result, the effects of reducing manufacturing equipment and production lines can be achieved, and the effect of greatly reducing initial investment costs and operating costs can be achieved. However, the metal stamping member includes a cavity portion for receiving an elastic element, such as a spring, for moving the scraper plate or knockout pin up and down. 6 200536630 When water-lubricating fluid is used as lubricant, this water-lubricating fluid will flow into the tank. Since this lubricating fluid contains moisture, the problem of elastic fatigue loss is caused by the prolongation of the spring thread of the spring made by the woman. Complex load — N 'has used resin-coated impeachment, but only a small amount of benefit for growth = Γ = :. And in the damaged part of the covering material, other factors will eventually see fatigue failure. Due to this, the spring inside the cladding material will be corroded. 10 15 20 Rust inhibitor can be added to this water lubricating fluid. However, if this water-lubricating fluid is left in the cavity portion of the built-in spring I member for a long time, the rust inhibitor added to the water-lubricating fluid may no longer prevent the fluid from remaining. By. The 'field fungus' & colony' fluid will have a bad last name and emit a strange smell. When the odorous lubricating fluid adheres to the product during processing, it will require post-treatment jade work, such as cleaning the product after stamping and guarding. β Therefore, the inventors of the present invention have considered that when a water lubricating fluid is used for processing, it is necessary to provide a means for discharging the lubricating fluid from the cavity portion for receiving the elastic member or device to prevent the lubrication. The fluid flows into the cavity portions and is provided at a metal stamper member such as a stamped plate. As for a device for discharging unnecessary materials, such as a lubricating fluid falling into a cavity portion of a mold, Japanese Patent Laid-Open Publication No. 09436133 (1997) discloses a technique in which perforations are provided on the bottom surface of the cavity of a main body of a forging mold. Used as a drain hole for lubricating fluid residue when forging. On the other hand, as recognized by the applicant and the inventor, there is no known technique related to the technique of preventing the lubricating fluid from flowing into the cavity portion of the metal stamper. 7 200536630 Although the technology disclosed in this Patent Publication No. 09-136133 (1997) is related to the discharge of unwanted lubricating fluid residues from the inside of a cavity, the object to be processed is directly inserted into the cavity for processing The difference between the present invention and the present invention lies in that its purpose is to drain the lubricating fluid that has flowed into the six parts of the mold or to prevent the lubricating fluid from flowing into the cavity parts, and to scrape the plate or knockout pin. Necessary elastic members are accommodated in these cavity portions. In addition, the technology as disclosed in Japanese Patent Laid-Open Publication No. 09-136133 (1997) does not presuppose the use of a water lubricating fluid. Therefore, the technique disclosed in Japanese Patent Laid-Open Publication No. 09-136133 (1997) does not solve the problems associated with the use of water > slip fluid. Accordingly, in the technology disclosed in Japanese Patent Laid-Open Publication No. 09-136133 (1997) (see Japanese Patent Laid-Open Publication No. 09-136133 (1997), paragraph [0017], Figures 1 and 2), it is considered unnecessary to The lubricating fluid that has flowed into the cavity portions is discharged or prevented from flowing into such cavity portions, and the elastic members necessary for the action of the scraping plate or the ejection pin are housed in the cavity portions. In contrast, the present invention presupposes the use of this water lubricating fluid. C Summary of the Invention In view of the foregoing, an object of the present invention is to provide a metal die member capable of preventing corrosion of an elastic member such as a spring, and by preventing unnecessary when a water-lubricating fluid is used for press working. The lubricating fluid stops on the tool to prevent the bad name of the fluid on these molds. To achieve this, the main element of an embodiment of the stamper member of the present invention provides a discharge path for draining the water lubricating fluid flowing into the cavity portion accommodated in the elastic member at least 8 200536630, to the Outside the mold cavity. With this configuration, even when the water lubricating fluid used for processing has flowed into the cavity portions formed on the metal stamper member, the lubricating fluid can be discharged to the outside of the cavity portions through the discharge path. Therefore, no water lubricating flow 5 is accumulated in the cavity portion of the stamper member, and it is possible to prevent the stamper member or the elastic member from being damaged, and to prevent the proliferation of bacteria caused by the residual water lubricating fluid. According to an embodiment of the present invention, it is also preferable that the discharge path is provided on an obstructing member, and the cavity portion is an inner surface including a perforation penetrating through one of the members constituting the stamper member, and at least a part is inserted into the 10 inside the perforation of the top surface of the obstruction member. With this configuration ', the ejection path can be mounted on and separated from the stamper member quite easily. And compared with the case where the discharge path is formed in other parts of the mold, the discharge path can be formed on the obstructing member quite easily because it is compared with other parts of the mold (stamped plate or 15 similar). Material), the obstruction member is quite small. Further, one of the main components of the stamper member of the present invention that is different from the other embodiments described above is that an inflow prevention device is provided to prevent water lubricating fluid from flowing into the cavity portion, which is provided for At least a part of the elastic member is accommodated to allow expansion and contraction of the elastic member. With this arrangement, substantially no water-lubricating fluid flows into the cavity portion formed in the pressure member. According to this, the beach of anhydrous lubricating fluid is left in the cavity portion of the mold member, so the problem of the corrosion of the mold and the elastic member and the problem of bacterial proliferation due to the water lubricating fluid will be solved. 9 200536630 The metal stamper member according to the present invention is provided with a discharge path ① to open> formed on a child mold member such as a stamping plate for receiving the elastic member to a small part of the branch cavity to discharge the lubricating fluid, so that The lubricating fluid can be discharged from the cavity portions through the exhaust path, thereby preventing the mold members from receiving the elastic members such as springs that are placed in the cavity portions. In addition, San Yu water lubricating fluid will be difficult to accumulate in these cavity parts, so it can be = the breeding of bacteria in these cavity parts. The odor caused by the bad name of the lubricating fluid can also be resolved. ~ The condition that the discharge path is provided on the obstructing member such as the plug body includes: H) the bottom of the cavity portions to receive the elastic members, and the discharge is easily mounted on the mold member and moved therefrom. from. Because the discharge path is provided on the obstructing member, it has a relatively small size compared to other mold members (such as stamping plates or the like). Compared with the discharge path provided on other mold members, the discharge path can be Quite easy way to set it up. 15. Further, in a state where the inflow preventing device is provided to substantially prevent the hydration body from flowing into the cavity portions in which the elastic members are housed, water lubricating fluid can be substantially prevented from flowing into the cavity portions. . With this, the problem of accepting the surplus of the elastic member placed in the cavity portions and the problem of the bad smell caused by the bad lubricating fluid in the cavity portions can be solved. 20 Brief description of the drawings The embodiments of the present invention will be described in detail with reference to the drawings by way of example, in which: FIG. 1 is a partial cross-sectional view showing a part of a metal stamper member (Embodiment 1) to which the present invention is applied; 200536630 FIG. 2 is a partial cross-sectional view showing a part of a metal stamper member (Embodiment 2) to which the present invention is applied; FIG. 3 is a partial cross-sectional view showing a part of a metal stamper member (Embodiment 3) to which the present invention is applied; 5 FIG. 4 is a partial cross-sectional view showing a part of a metal stamper member (Embodiment 4) to which the present invention is applied; FIG. 5 is a partial cross-sectional view showing a part of a metal stamper member (Embodiment 5) to which the present invention is applied; FIG. 7 is a partial cross-sectional view showing a part of a metal stamper member (Example 6) 10 to which the present invention is applied; FIG. 7A is a view showing a method for manufacturing a heat exchange fin; and FIG. 7B is a view showing a heat exchange fin The detailed description of the preferred embodiment of the third embodiment 15 In the following, the present invention is applied to an example of manufacturing a heat exchange fin using a metal stamper member according to the present invention. Detailed description with reference to the drawings, FIGS. 1 to 6 are partial cross-sectional views showing Embodiments 1 to 6, in which the present invention is applied to an ironing punch 2 near a metal die member, which is used for the ironing process. 20 Example 1 As described in the related conventional art, a thin metal plate is given a pre-forming process and a perforation and punching process until it reaches an ironing process. The original metal stamper for the heat exchange fins The component is composed of an upper mold and a lower mold which can be opened and closed, and an ironing mold (not shown in 11 200536630) and the rest are held in a stamp template (not shown) containing the upper mold. The other side is that the ironing punch 2 is fixed at the stamping plate 1 containing the lower die. A scraping plate 3 is arranged above the stamping plate and away from the plate a predetermined distance of 5. The scraper plate 3 is elastically supported by springs (winding springs) 5 which serve as elastic members. The scraper plate 3 is perforated to define a perforation%, and the tip portion 2a of the ironing punch 2 can pass through The perforation 3a and the position of the scraper plate 3 can be adjusted so that when no load is applied The tip portion 2a of the ironing punch 2 is lower than the top surface of the scraping plate 3 when it is on the scraping plate 3. 10 The spring 5 is configured to elastically support the scraping plate 3 by at least a part It is placed in the cavity portion 6 formed on the lower stamping plate 丨 and its 疋 is on the upper side. In the embodiment shown in Figure 1, the lower part of the springs $ is placed in the cavity. In the embodiment shown in Fig. 1, the cavity portions 6 include the inner surface of the perforation la formed on the lower die stamping plate 1 and the upper surface of the plug body (obstructing member) 7. On the surface, the plug bodies 7 are inserted into the perforations 1 a and are screwed into the perforations 1 a. The perforations are provided at the central part of the plug bodies 7, which include the holes that have flowed into the cavity portions 6 The lubricating fluid is used for the discharge path 8. In this way, when the discharge path 8 is provided at the plug body 7, it has an example that the discharge path 8 is formed on the stamping plate 1, which has a larger size than the plug body 7, The discharge path 8 can be formed quite easily, as in the other embodiments, which will be described in detail later. In this embodiment, although there is only one discharge path 8 provided in the single cavity portion 6, a plurality of discharge paths 8 may be provided on the single cavity portion 6. Further, although in this embodiment 12 200536630 the discharge path shuttle 8 is assumed to have a cylindrical shape, the wearing surface shape of the discharge path 8 is not limited to a circle, but may be assumed to have a different shape, and the discharge The shape and / or cross-section of the path 8 may also vary in the longitudinal direction. A manufacturing method of the stamping process using the metal stamper member of the above-mentioned structure and the water-lubricating fluid for heat exchange fins will be described in detail. 10 15 20 A thin metal plate that has been subjected to the perforation and punching process is sent to the upper mold (not shown) and the lower die of the metal stamper member for heat exchange rotors (the part of the ironing punch is shown) Between the upper mold and the lower mold. At this time, when the upper mold starts to descend, the lower stamping member (not shown) provided on the upper mold will abut against the 4 metal plate 11 that has been conveyed to the scraper to punch out. The board 3 faces downward and resists such elastic force. Then, the pressure punch 2 has passed through the large end portion of the perforation 3 a of the scraping plate 3 and then extends to the top surface of the scraping plate 3. The tip portion of the top surface of the scoring 2 = except the top surface of the plate 3 is inserted into the protruding portion 11a which has been completed in the perforation and punching process, as shown by the dotted line in FIG. 1, and the thin :. By using the convex portion ua for relative positioning, the anti-hot pressing punch 2 is vertically pushed down by the upper die, and the pressing punch 2 will go through the second part 1-shaped part by itself. " For example, the extension 11a can be formed as a tube having a prostitute height. The upper mold and the lower mold are closed. After the mold is closed, the upper mold can be used to complete the ironing mold work to open the upper mold toward 3. Call to proceed. When the upper die is moved upward 13 200536630, the end of the ironing punch 2 will be withdrawn from the die, and the tubular portion formed by the ironing work will be pulled out of the die. A push-out pin (not shown) or a release pin (not shown) is usually provided on the upper mold so that the side tubular portion can be reliably pulled out of the stamp. The tubular portion is pushed out of the die by a push pin (not shown) or a release pin (not shown). When the tubular portion has been locked on the side of the ironing punch 2, the scraper plate 3 will use the spring force of the springs 5, which has released the compression force when the upper mold is raised, relative to the ironing punch. The head 2 is raised considerably so that the tubular portion can be released from the restriction of the ironing punch 2. 10 After the ironing process, the thin metal sheet 11 (processed material) is sent to a reflaring process, which bends the tip of the collar outward. The thin metal plate 11 is then cut into a specific shape to obtain a heat exchange fin. When the heat exchange fins are formed by the above-mentioned stamping process, the lubrication effect between the 15 special stamps and the material to be molded can ensure that Usability will be important. So far, the lubricating effect has been the use of lubricating oils containing volatile hydrocarbon components. The inventors of the present invention propose to use water to lubricate the fluid instead of such a lubricating oil to reduce the environmental burden. Unlike hydrocarbon-based lubricants, hydrocarbon lubricants are fully applied to the surface of the material before processing (before the material is sent to the die member). When water is used to lubricate the fluid, It is considered as a method of locally applying the fluid to a desired position, and should not be used for the purpose of avoiding the elution or peeling of the lubricating coating formed on the surface of the thin metal plate containing the material, so that the lubricating fluid supply path ( (Not shown) 玎 is provided in the stamper member. 14 200536630 In this way, when the lubricating fluid supplied from the lubricating fluid supply path provided on the stamps is used to lubricate the stamps and materials to be processed, the lubricating fluid left after lubrication or excessive The supplied lubricating fluid will enter the cavity portion of the lower stamp. In the metal stamper member of the present invention, 5 the cavity portions 6 into which the lubricating fluid flows therein are formed with a discharge path 8 for discharging the lubricating fluid so that the lubrication that has flowed into the cavity portions 6 The fluid will be discharged immediately via these discharge paths 8. Accordingly, it is difficult for the water lubricating fluid that has flowed into the cavity portions 6 to remain in the cavity portions 6. This will prevent corrosion of the lubricating fluid due to bacterial proliferation. This can also prevent the occurrence of odor due to the corrosion of the lubricating fluid, and can reduce the problem of cleaning the heat exchange fins to prevent odor after processing. In addition, since the lubricating fluid that has flowed into the cavity portions 6 can be discharged relatively quickly from the cavity portions 6, it is also possible to suppress the springs 5 received in the cavity portions 6. Bad last name. 15 In view of this, in order to prevent the erosion of the spring in a more complete manner, the spring 5 should be made of a waterproof material. A cylindrical spring 5 made of a resin material such as urethane, a coil spring 5 made of waterproof stainless steel, or a spring 5 with a waterproof coating can be used. Embodiment 2 20 FIG. 2 shows Embodiment 2 which is different from Embodiment 1 described above. In the second embodiment, it is different from the first embodiment shown in FIG. 1. The cavity portions 6 in which the springs 5 are housed are formed as flat-bottomed holes formed on the top surface of the stamping plate 1. on.

In Example 3, the cavity portions 6 for receiving the springs 5 include an inner surface of a perforation formed on the stamping plate 1 and a top surface of a back plate 13 provided under the stamping plate. . The discharge path 8 communicated with the cavity portions 6 is formed through the back plate 10 so that, similar to the above embodiment, the lubricating fluid that has flowed into the cavity portions 6 can pass through the discharge paths 8 discharge. Since other configurations are the same as those of the above-mentioned embodiment, the same components will be denoted by the same reference numerals, and descriptions thereof will be omitted. Embodiment 4 15 FIG. 4 shows Embodiment 4 which is different from the above embodiment. In Example 4, the back plate 13 does not form a perforation as a discharge path for discharging the lubricating fluid that has flowed into the cavity portions 6, but a g 8b communicating with the cavity portions 6 is used. It is formed on the top surface of the far plate 13. This groove 8b is formed so as to extend upward to the peripheral edge of the outer ring of the? Meniscus 13. In this way, by setting the groove% 20, the lubricating fluid that has flowed into the cavity portions 6 can be discharged through the groove. Since other configurations are the same as those of the above-mentioned embodiment, the same components will be denoted by the same reference numerals and descriptions thereof will be omitted. In this way ', although the groove 8b is formed on the top surface of the back plate 13, it can also form a similar groove (not shown) on the lower surface of the stamping plate. 16 200536630 Embodiment 5 FIG. 5 shows Embodiment 5 which is different from the above embodiment. In Embodiment 5, the spring-shaped covers 16 are covered by the tubular cover 16. The outer peripheral surfaces of the lids 16 fit inwardly on the inner surfaces of the mold cavities 6 to allow smooth sliding motion. A gasket (0-ring) I7 is provided on a higher position of the inner surface of the cavity portions 6 to substantially prevent lubricating fluid from the outer peripheral surface of the covers 16 and the cavity portions 6 The gap between the inner surfaces of the fins flows into the six sections 6 of the mold. φ In the embodiment shown in FIG. 5, the cover 16 and the gasket 17 are provided to prevent the lubricating fluid from flowing into the cavity portions 6 so that the lubricating fluid can be substantially prevented from flowing into the cavity. Inside the cavity portion 6. As shown in the figure, the plug bodies 7 are preferably provided with perforations 18. These perforations 1 § can also provide an outgassing effect in the space in which the springs 5 are housed. If the lubricating fluid enters the inside of these cavity portions 6, it can also be used as a diameter of the lubricating fluid discharge path. Since other configurations are the same as those of the above-mentioned embodiment, the same components will be denoted by the same reference numerals and descriptions thereof will be omitted. # EMBODIMENT 6 FIG. 6 shows Embodiment 6 which is different from the above embodiment. Embodiment 6 The embodiment 5 is different from the embodiment 5 shown in FIG. 5 in that the cavity portions 6 for containing the springs 5 are internal surfaces and settings including perforations ^ formed on the stamping plate 1.
