200904561 九、發明說明 [相關申請案] 本申請案與2007年4月16日提申名稱爲“METHOD AND APPARATUS FOR FORMING BEND CONTROLLING DISPLACEMENTS IN SHEET MATERIAL，，的美國專利暫時 申請案第6 0/9 1 1,9 1 0號有關，該案的全部內容藉此參照 而被倂爲本文的一部分。 【發明所屬之技術領域】 本發明大體上係有關於形成用來控制板材上的位移之 彎折處的設備其其使用方法。 【先前技術】 用來在各種板材上形成能夠精確地控制板材的彎折之 細縫，溝槽，位移的各種技術或製程及其它手段係屬習知 。這些手段包括雷射切割，水刀切割，衝鍛，衝孔，模製 ，立體平版印刷成型（stereo lithography)，滾壓成形， 機械加工，化學硏磨，光蝕刻及類此者。這些手段可被應 用到各種由板材形成的結構上。這些結構通常都需要複雜 且精確的彎折圖案，且這些結構的設計對於抗扭力要求較 不強調。可用金屬板形成且包含精確且複雜的彎折的結構 的一個例子爲電腦所用之電子構件機殼。其它種類的結構 可包括電子外殼，汽車零件，運輸構件，建築構件， HVAC構件，航空構件，履帶，聲音接受器，電視機， 200904561 DVD播放器，及類此者。 例如，美國專利第7，1 52,449號掲露板材的開縫及/ 或開槽以及使用“撿取並放置（pick-and-place) ”技術將 電子構件安裝至平板上，其中該等構件係在板材彎折之前 安裝到該平板上。這些平板然後被彎折成爲外殼，該等電 子構件都在該外殼的內部中在所想要的位置處彼此空間上 相關聯。該“撿取並放置（pick-and-place ) ”技術大幅度 地降低成本，因爲它具有用低力量彎折技術來將一平板彎 折成一尺寸精確的槪殼的能力。雖然此一電子機殼可使用 雷射切割或水到刀切割處理來形成，但這些處理典型地相 當昂貴。當然，其它的技術可被用來取代或配合上述的技 術。這些其它的處理包括位移成形技術，譬如像是衝鍛， 衝壓’滾壓成形，及類此者。位移成形處理特別適合用在 板材上，特別是，但並非一定是，比切割處理來得便宜。 一機器壓機可被用來在板材上產生位移。例如，轉塔 式壓機及其它染式加工手段通常被用來實施相對小量的生 產，包括原型件的製造及其它小量的生產。相對大量的生 產通常是用壓印機其它機構來實施，亦即，爲了特定的零 件的製而設計且專屬之加工機具。在任何一種情形中，機 器壓機包括了包含一或多個公的衝頭與一或多個對應的模 具的機具。此種機具之衝頭與模具組通常是用硬化鋼材或 其它硬化金屬來製成，它們在製造上是很昂貴的。再者， 機器壓機的重復使用會產生正常的磨損，這會讓衝頭及模 具很快地鈍掉。該機器壓機的精確度因而降低，這將導致 -5- 200904561 所生產的零件品質降低。鈍掉的衝頭與模具亦會在M $ 面磨損並進一步導致“鈍化”的零件，亦即，零件的形狀 尺寸比所想要的或所設計的形狀及尺寸的精確彳生胃。胃 及模具可被磨銳，但是，這通常很昂貴且耗時，且會到 該機器壓機的停機時間，並造成額外的花費及降低產出 〇 在板材上製造用於彎折之複雜的結構需要相同的複 系統及處理，這將會導致更高的加工成本。在製備具有 數的結構及特徵的板材時，製造複雜對會大量地增加。 統的技術需要用一種工具來製造相對簡單的特徵及使用 —工具來製造其它的特徵。 又，通常用於較快速及大量製造上之硬質工具與軟 工具比較其來其在製造上較昂貴且更沒有彈性。因此， 統的硬質加工技術需要在成本及彈性上妥協，而軟質加 技術則需要在製造時間及小量製造上妥協。 有鑑於以上所述，具有一種可克服已知機器壓機的 述及其它缺點的方法與設備是有利的。再者’對於進一 降低製造及工具成本存在著不間斷的需求。 【發明內容】 本發明的一個態樣係有關於一種工具總成，用來在 板材上形成適合沿著一彎折線之控制彎折的位移。該工 總成包括一或多個衝壓片，一衝壓片塊體其具有一或多 被建構成可接納該等衝壓片的大小及形狀的凹部’一模 方 及 頭 成

可脹大的墊片包括內螺紋用來與該提取器螺紋式嚙合。 該模具塊體單元包括一容置部其被建構來可移除地容 納該模具塊體。該容置部可具有一通道。該容置部可具有 一形狀其實質上對應該模具塊體的形狀。該容置部可被建 構來容納兩個模具塊體。該二模具塊體可彼此被定向一角 度。該模具塊體可包括一剪切棒及一榫接（joggle)棒。 該W切棒與該榫接棒可包括匹配面。該匹配面可以是傾斜 的。該模具塊體可包括一或多個塡隙片。該模具塊體可包 括放電加工的硬化鋼。該模具塊體可包括多個第一剪切面 及多個第二剪切面’其中當第一剪切面被磨損之後，該模 具塊體可從該模具塊體單元上被取下，被上下顛倒，且被 插入到該模具塊體內以利用第二剪切面。 本發明的另一態樣係有關於一種衝壓機器其包括上述 的工具總成中的任何一種及/或利用上述方法中的任何一 種方法。本發明的再另一態樣係關於在板材上形成可制彎

成控制彎折的位移用以形成各種摺疊形狀及構形之摺疊線 ，其包括了但不侷限於揭露在美國專利第6,481，2 5 9號， 美國專利第6,877,349號，美國專利第7,152,449號，美 國專利第7,152,450號，美國專利申請案第10/821,818號 (現爲美國專利公開案第2005/0005670 A1號），及美國 專利第7,〇32,426號，美國專利申請案第10/931,615號（

不侷限於電子構件機殼，汽車零件，器具構件，運輸構件 ，建築構件，RF屏蔽，HVAC構件，航空構件，及類此 者。此類機殼通常是極爲複雜用以能夠將多種構件以三維 度陣列的方式設置在用於電子設備的該外殼的內部中。因 爲了射切割與水刀切割這兩者都相對昂貴，所以使用相對 低的成本，高產出率之位移成形技術，譬如衝壓，壓印， 滾壓成形等等，來形成用於電子設備的機殼，以及許多其 它低成本的外殼是所想要的。根據製造應用的特定內容， 該等位移成形技術可以是切割及/或其它成形技術的替代 或輔助處理。因此，本申請案顯示這些位移成形處理可以 如何被使用在板材上。 繼續參考圖1，該衝壓系統3 0包括一上衝頭總成3 5 與~對應的下模具總成3 7的工具，它們較佳地以滑動方 式彼此鍵合（k e y e d )，使得它們以傳統方式朝向/遠離彼 此地往復運動。所示的實施例爲“向下形成”因爲位移是被 向下形成的。吾人將可瞭解的是，該總成可被顛倒設置， 該模具總成被設置在該衝頭總成上方（即，“向上形成”） ’或向上形成與向下形成形態的組合。相同地，該衝頭總 成與該模具總成可以其它適合的方可式彼此移動地加以安 裝。例如’該衝頭總成與該模具總成可被安排成彼此水平 地往復運動。圖中所示之垂直定向的配置具有一些好處。 -11 - 200904561 例如，垂直定向的配置可以單純地將工件上置在下總成上 且藉由重力來將其保持在定位。這在重撃（cl〇bbering) 中是特別有用。例如，當該衝壓處理亦將該板材的周邊剪 切掉時，此配置通常無需將工件相對於上及下總成加以特 別放置。在此例子中，一線圏架及一給料器可被設置用以 將線圈架饋給至該衝壓系統，以輔助或取代人工放置及機 器放置。 如在圖2的工件中所示，該衝壓系統可被用來在該工 件上形成多個位移。在此特定的例子中，該衝壓系統將該 工件形成爲一中間物件其包括多個控制彎折的位移3 2以 及多個其它的位移特徵結構譬如像是一突出構件架座39 ，碰鎖凸片（latch tab) 40 及碰鎖錨（latch anchor) 42 。吾人將可瞭解的是，該衝壓系統亦可被建構來提供更少 或更多的位移特徵結構及/或切割或將該工件形成爲一特 定的長度及/或形狀。 持續參考圖2，示範性的控制彎折的位移可沿著預定 的或所想要的彎折線44以一種類似於細縫，舌件的方式 及上文中提到的專利與專利申請案中描述的位移的方式被 形成。在所示的實施例中，這些位移包括一平的區域4 6 及一傾斜的過渡區域47，如在上文中提到的‘828申請案 中描述的。該平的區域係實質上平行於該板材的整個平面 ’而該過渡區域以該‘828申請案中的圖18A所示的方式 相對於該板材的其餘部分的一角度延伸並與該平的區域互 連。 -12- 200904561 該等控制彎折的位移大體上係藉由在該板材的厚度方 向上的位移來形成，使得該位移最靠近該彎折線的周邊部 分可提供一邊緣及一對應的相對面其被建構且設置成可在 後續的之將2D板材彎折成爲一 3 D產品的期間可產生邊-對-面的嚙合，其通常爲上述‘828申請案中所描述之剪切 平行且鄰近該摺疊線所造成的結果。該所示的控制彎折的 位移包括一平的區域其具有一細長的部分其具有大致半圓 形的端部。吾人將可瞭解的是，該平的區域的實際形狀改 變。例如，具有多個半徑的曲線可被用來形成該細長的部 分及端部，及卵形，橢圓形，拋物線及/或其它適合的彎 曲形狀亦可被使用。 通常，一特定板材所需要之控制彎折的位移的形態可 根據該板材的形狀及形態而改變。在一些情形中，將該等 細長的位移的尺寸“標準化”的好處爲可降低工具成本並簡 化設計處理及工具維修。例如，該等細長的位移可被標準 化成爲一，二，三或多個用於一特定的板材厚度，特定種 類的材料及/或其它參數之“標準”的尺寸。 現翻到圖3，上衝頭總成3 5包括多個硬化的衝壓片 49，它們被設置成可形成該等控制彎折的位移於該板材上 。該上衝頭總成亦包括其它衝頭用以形成其它特徵結構於 該板材上’譬如像是架座衝頭5 1及碰鎖衝頭5 3。所示的 衝頭總成因而可被同來同時地沿著多條彎折線形成控制彎 折的位移及其它特徵，包括該架座及/或碰鎖件。當然， 該衝頭總成亦可被建構來形成各式特徵，其與某些特徵是 -13- 200904561 分開的，或是添加上去的。吾人將可理解的是，對應 模具總成3 7包括數個形狀互補的特徵，以協助形成 材之各式位移特徵。 爲了要方便維修服務及可調整性，該上衝頭總成 一衝頭單兀5 4及該下模具總成包括一模具單元5 6， 係可取下地被安裝到一傳統的衝壓機器5 8上。這兩 元可藉由任何適合的機構，其包括但不侷限於有螺紋 固件（如’模體緊固件60 )，暗榫及/或其它適合 構，而被緊固到該架座及/或該衝壓機的上部與下部 較佳地，該衝頭單元及/或該模具單元都不是用硬化 成的，因此其加工製造成本比使用硬化鋼來得便宜。 現翻到圖4，其顯示出一衝壓片或矛插入件（： i n s e rt ) 4 9及位於該模具塊體6 1之對應的矛凹穴的 。該矛插入件與該模具塊體較佳地但非必要地爲模組 ，它們可被方便且快速地更換，且它們可被轉轉動而 面，或端對端，用以呈現新鮮的切割緣給該剪切部分 某些態樣及在某些例子中，該矛插入件及模具塊體可 爲是可拋棄的。如將於下文中更細部地說明地，該矛 件及模具塊體的模組形態可容許便宜且有效的硬質工 計。詳言之，該模組形態可減少用硬化金屬所製成的 及減少開發一用來將工件形成爲特定的板材產品之硬 具設計所需的機械加工量。較佳地但非必要地，該矛 件及/或該矛凹穴是用預先硬化的庫存料來製成，其 硏磨，硬軋碾及/或放電加工（EDM )成爲最終的形 的下 該板 包括 它們 個單 的緊 的機 上。 鋼製 lance 形態 構件 面對 。在 被視 插入 具設 構件 質工 插入 可被 狀。 -14- 200904561 吾人將可瞭解的是，其它適合的機構亦可被用來將該預硬 化的庫存料形成爲最終之所想要的形狀。 現翻到圖5及圖6，一示範性的矛插入件次總成63 包括多個矛插入件49它們被安裝在一示範性的衝壓片塊 體6 5中，該衝壓片塊體接著被安裝到該上衝頭單元3 5上 。該等矛插入件較佳地但非必要地可從該衝壓片塊體上被 取下，該衝壓片塊體較佳地可從該上衝頭單元取下。該矛 頭插入件的形態及尺寸大致上順從該檔控制彎折的位移 3 2的平的區域46之所想要的形狀。因爲該等矛插入件遭 受到比該系統的其它構件更大的磨損及撕裂，所以它們可 取下的造構有助於它們在該衝頭單元在該衝壓機上時重新 放置或更換，進而減少該衝壓機的停機時間，並支援規律 的表定維修。 該衝壓片次總成較佳地但非必要地具有一實質上模組 式設計，每一次總成都在尺寸及形狀上對應到一或多個沿 著一彎折線配置的細長形位移。在所示的實施例中，該次 總成被建構來形成控制彎折的位移，然而，吾人將可瞭解 的是，一個，兩個’三個或更多個矛插入件可被用來形成 與沿著一彎折線的細長形位移數量相對應的數量。吾人將 可瞭解的是，該等矛插入件的數量及尺寸可隨著被形成之 產品的特定設計條件而改變。 在所示的實施例中’每一矛插入件都被容納於該衝壓 片塊體的示範性對應衝壓片凹部67中且較佳地但非必要 地藉由一適當的緊固件被固定於其內。如圖7所示，該矛 -15- 70 200904561 頭插入件可被設置棘爪68其與一對應的可脹大的墊片 嚙合用以將該矛插入件牢牢地固定在定位上。在所示的 施例中，該可脹大的墊片是有螺紋的，然而，吾可將可 解的是其它適合的機構亦可被使用。 被夾在該衝壓片塊體6 5與該衝頭單元5 4之間的是 示範性的硬化的衝壓片基座72，該等矛插入件49抵靠 該衝壓片基座。如圖中所見，該衝壓片基座可由一平的 化金屬板來形成，該金屬板可被容易地且相對便宜地被 壓或以其它方式製造。很重要的是，此構造可讓該衝壓 塊體65用非硬化的金屬來製造，這可進一步大幅降低 本，因爲與傳統之硬化的衝壓片塊體比較起來，非硬化 衝壓片塊體可用較便宜的方式且在較短的時間內被製造 現翻到圖8A至圖8C，當該緊固件被固定且被精確 定位時，該等矛插入件的內端抵靠著該插壓片基座使得 矛插入件從該插壓片塊體65延伸出，以形成具有所想 的位移深度之控制彎折的位移。較佳地，該棘爪6 8具 一內凹的輪廓74其可讓該可脹大的墊片將該等矛插入 49推頂住該衝壓片底座72並將該矛插入件牢牢地緊固 該衝壓片塊體65的凹部67內，如圖8C所示。而且， 插入件49被製造成可讓衝壓片從該衝壓片塊體65向外 伸一最小的量。此構造提供該等矛插入件更大的側向穩 性，因而將該等矛插入件的彎折力矩最小化，藉以延長 耗並降低裂痕的可能性。吾人將可理解的是，在使用脫 板（stripper plate )的例子中，該等矛插入件可從該衝 實 理 著 硬 衝 片 成 的 〇 地 該 要 有 件 在 矛 延 定 磨 模 壓 -16- 200904561 片塊體向外延伸一相當的長度用以配合該脫模板的厚 得矛插入件延伸穿過該脫模板並由該處向外延伸。 較佳地，矛插入件與可致當的墊片被建構成可方 插入件從該衝壓片塊體取下。在所示的實施例中’可 的墊片70具有內螺紋75且棘爪68具有一肩部77用 進矛插入件49從該衝壓片塊體65上取下’如圖8D 8F所示。詳言之，一移除螺栓 79形式的提取 extractor)可被用來與該可脹大的墊片7〇螺紋地嚙 用以將矛插入件由該衝壓片塊體中拉出。如圖8E中 ，該可脹大的墊片將與該肩部7 7嚙合並容許該提取 著矛插入件49施加向下的力量並移除該矛插入件。 取器可進一步包括一桿81或其它適合的機構用以施 下的力量，如圖9中的箭頭F所示。 在所示的實施例中’矛插入件具有平的端部’亦 端部的底面實質上平行於該板材的其餘部分及/或平 該衝壓床。此一平的構造的好處在於’在矛插入件上 損較少及延長矛插入件的使用壽命。例如’具有平的 之矛插入件的磨損比發生在具有斜的底部之衝頭上之 磨損要少很多。再者’斜的底部的工具通常磨損的較 製造上更昂貴且更難重新塑形。較佳地’矛插入件在 及垂直方向都對稱，使得當衝壓片塊體的—個邊緣磨 ’該衝壓片塊體可繞著其垂直軸線被轉1 8 0度用以利 兩個上緣（即，圖7中所示的邊緣8 2 ’ 8 2 ’ ’ 82 ”及 )。因此，矛插入件的使用壽命可變成兩倍或四倍’ 度使 便矛 脹大 以促 至圖 器（ 合， 所示 器對 該提 加向 即， 行於 的磨 底部 快速 快， 水平 損時 用其 8 2，，， 因爲 -17- 200904561 每一矛插入件都有四個剪間緣，且一此只使用到一個剪切 緣。 現翻到圖1 〇至圖1 3，一模具塊體次總成8 4包括模 具塊體61其可移除地位在該模具單元5 6內。關於此點， 該模具單元包括一通道8 6用來可移除地容納該模具塊體 。如上文中提及的，該模具單元可用非硬化的金屬製成， 因此該通道可用不同於該模具塊體之相對便宜的方式來製 造或加工。 在另一方面，該模具塊體61是用硬化的鋼及/或其 它硬化的金屬來製造。因爲該模具塊體相對小，所以模具 塊體可使用硬化的金屬用之標準加工技術來快速地加工製 造。例如，該模具塊體可使用放電加工（EDM )或其它適 合的機構來加工製造。無論如何，只有相對小的模具塊體 被硬化，且容納該模具塊體的該模具單元可以是未被硬化 的。因此，EDM及其它相對昂貴的硬加工/製造處理只有 在製造較小的零件及簡單的形狀時才需要，因此對於時間 及金錢上的節省有很大的貢獻。 參考圖1 2，模具塊體6 1的構造及尺寸大致上都順應 該控制彎折的位移之所想要的高度輪廓（elevational profile )。在所示的實施例中，該模具塊體包括四個模具 塊體凹部88它們的尺寸及位置被安排成與四個矛插入件 4 9相配合’用以在該板材3 3上形成四個位移。如上文中 提到的’矛插入件在形狀上實質對應於該位移32之所想 要的平的區域46 ’亦即該所想要的平的區域的下凹內表 -18- 200904561 面。該模具塊體凹部88在另一方面在形狀上與該平的區 域4 6及該過渡區域4 7之所想要的形狀實質相符，亦即， 其突出的外表面。應注意的是，在此例子中，“內表面，，與 “外表面”只是指位移的形狀，亦即“內表面，，被用來表示在 該板材上由該等矛插入件所形成的下凹區域，而“外表面，， 則被用來該位移從該板材之其餘部分突伸出的區域。 該模具塊體44包括一剪切緣89它的尺寸及位置被建 構成可讓它與一矛插入件49的一鄰接緣合作用以造成該 位移實質上平行於及/或沿著彎折線剪切。詳言之，介於 該模具塊體4 4的剪切緣與一對應的矛插入件4 9之間之很 小的公差（tolerance )將造成該位移32之平的區域46實

[Description of Application] This application filed with the name of "METHOD AND APPARATUS FOR FORMING BEND CONTROLLING DISPLACEMENTS IN SHEET MATERIAL" on April 16, 2007. , US Patent Provisional Application No. 6 0/9 1 1, Related to 9 1 0, The entire contents of this case are referred to as part of this article by reference. TECHNICAL FIELD OF THE INVENTION The present invention is generally directed to an apparatus for forming a bend for controlling displacement on a sheet material, the method of use thereof. [Prior Art] It is used to form a slit on various sheets which can precisely control the bending of the sheet, Groove, Various techniques or processes for displacement and other means are known. These tools include laser cutting, Waterjet cutting, Forging, punching, Molding Stereolithography (stereo lithography), Roll forming, Machining, Chemical honing, Photo etching and the like. These means can be applied to a variety of structures formed from sheet materials. These structures often require complex and precise bending patterns. And the design of these structures is less emphasized for the torsion resistance requirements. An example of a structure which can be formed of a metal plate and which contains a precise and complicated bend is an electronic component casing for a computer. Other types of structures may include an electronic housing. car parts, Transport component, Building components, HVAC components, Aviation components, track, Sound receiver, TV set, 200904561 DVD player, And this class. E.g, US Patent No. 7, 1 52, Slotting and/or grooving of the No. 449 enamel sheet and mounting the electronic components to the slab using a "pick-and-place" technique, Where the components are attached to the panel prior to bending of the panel. The plates are then bent into a casing, The electronic components are all spatially associated with each other at the desired location in the interior of the housing. This “pick-and-place” technology dramatically reduces costs. Because it has the ability to bend a flat plate into a precisely sized clamshell with low-force bending techniques. Although this electronic enclosure can be formed using laser cutting or water to knife cutting, However, these processes are typically quite expensive. of course, Other techniques can be used in place of or in conjunction with the techniques described above. These other processes include displacement forming techniques, For example, like forging, Stamping 'roll forming, And this class. The displacement forming process is particularly suitable for use on sheets. especially, But not necessarily, It is cheaper than cutting. A machine press can be used to create displacement on the sheet. E.g, Turret presses and other dyeing processes are often used to carry out relatively small quantities of production. Including the manufacture of prototypes and other small quantities of production. A relatively large amount of production is usually carried out by other mechanisms of the embossing machine. that is, Designed and designed for specific parts. In either case, The machine press includes a implement that includes one or more male punches and one or more corresponding molds. The punches and die sets of such implements are usually made of hardened steel or other hardened metal. They are very expensive to manufacture. Furthermore, Repeated use of the machine press produces normal wear and tear. This will cause the punch and mold to blunt quickly. The accuracy of the machine press is thus reduced, This will result in a reduction in the quality of the parts produced by -5-200904561. The blunt punch and die will also wear on the M $ face and further cause "passivated" parts. that is, The shape of the part is precisely the size of the desired or designed shape and size of the stomach. The stomach and mold can be sharpened, but, This is usually expensive and time consuming. And will go to the downtime of the machine press, And incurring additional costs and lowering the output 〇 The same complex system and treatment is required to make the complex structure for bending on the board. This will result in higher processing costs. When preparing a sheet having a number of structures and features, Manufacturing complexes will increase in large numbers. The technology requires a tool to make relatively simple features and use tools to make other features. also, Hard tools, which are commonly used for faster and mass production, are more expensive and less flexible in manufacturing than soft tools. therefore, Hard processing technology needs to compromise on cost and flexibility. Soft plus technology requires compromises in manufacturing time and small manufacturing. In view of the above, It would be advantageous to have a method and apparatus that overcomes the described disadvantages of known machine presses. Furthermore, there is an ongoing need to further reduce manufacturing and tooling costs. SUMMARY OF THE INVENTION One aspect of the present invention relates to a tool assembly.

It includes, but is not limited to, disclosure in US Patent No. 6, 481, 2 5 9 , US Patent No. 6, 877, No. 349, US Patent No. 7, 152, No. 449, US Patent No. 7, 152, No. 450, U.S. Patent Application Serial No. 10/821, No. 818 (now US Patent Publication No. 2005/0005670 A1), And US Patent No. 7, 〇32, No. 426, U.S. Patent Application Serial No. 10/931, No. 615 (now US Patent Publication No. 2005/0097937 A1), US Patent Application No. 1 0/98 5, No. 73 (now US Patent Publication No. 2005/0061049 A1), US Patent Application No. 11 / 3 57, No. 934 (now US Patent Publication No. 2006/026 1 1 39 A1), US Patent Application No. 1/952, 3 5 7 (now US Patent Publication No. 2005/0064138 A1), US Patent Application No. 11 / 3 84, No. 216 (now US Patent Publication No. 2006/02072 1 2 A1), US Patent Application No. 1 1/0 80, 2 8 8 (now US Patent No. 7, 3 5 0, 3 90 B 2), U.S. Patent Application No. 3/74, No. 828 (now US Patent Publication No. 2006/02 1 3 24 5 A1), US Patent Application No. 1 1 / 1 80, No. 3 9 8 (now US Patent Publication No. 2006/002 1 4 1 3 A1), U.S. Patent Application No. 1 1/290, No. 968 (now US Patent Publication No. 2006/0075 79 8 A1), And U.S. Patent Application No. 11/4 11, Various folding shapes and configurations of No. 440, The entire contents of these patents and patent applications -10-200904561 are incorporated herein by reference. Some of the applications for precise bending of panels as described in the above application relate to the manufacture of 3D articles, These 3D objects include, but are not limited to, electronic component housings. car parts, Appliance component, Transport component Building components, RF shielding, HVAC components, Aviation components, And this class. Such enclosures are typically extremely complex to enable a plurality of components to be placed in a three dimensional array in the interior of the enclosure for an electronic device. Because both the cutting and the waterjet cutting are relatively expensive, So using relatively low cost, High-output displacement forming technology, Such as stamping, Embossing, Roll forming, etc. To form a casing for an electronic device, And many other low cost enclosures are desirable. Based on the specific content of the manufacturing application, Such displacement forming techniques may be an alternative or ancillary treatment of cutting and/or other forming techniques. therefore, This application shows how these displacement forming processes can be used on a board. Continue to refer to Figure 1, The stamping system 30 includes a tool for an upper die assembly 3 5 corresponding to the lower punch assembly 3 5 . They are preferably bonded to each other in a sliding manner (k e y e d ), They are caused to reciprocate toward/away from each other in a conventional manner. The illustrated embodiment is "formed down" because the displacement is formed downward. What we will understand is that The assembly can be set upside down, The mold assembly is disposed above the punch assembly (ie, "Upward formation") or a combination of upward formation and downward formation. identically, The punch assembly and the mold assembly can be mounted in other suitable manners to move relative to each other. For example, the punch assembly and the mold assembly can be arranged to reciprocate horizontally relative to one another. The vertically oriented configuration shown in the figure has some benefits. -11 - 200904561 For example, The vertically oriented configuration simply places the workpiece on the lower assembly and holds it in place by gravity. This is especially useful in cl〇bbering. E.g, When the stamping process also cuts the periphery of the sheet, This configuration usually does not require special placement of the workpiece relative to the upper and lower assemblies. In this example, A line truss and a feeder can be provided to feed the bobbin to the stamping system. To assist or replace manual placement and machine placement. As shown in the workpiece of Figure 2, The stamping system can be used to create multiple displacements on the workpiece. In this particular example, The stamping system forms the workpiece as an intermediate member that includes a plurality of displacements 3 2 that control the bend and a plurality of other displacement features such as a protruding member mount 39, A latch tab 40 and a latch anchor 42 are provided. What we will understand is that The stamping system can also be constructed to provide fewer or more displacement features and/or to cut or form the workpiece to a particular length and/or shape. Continue to refer to Figure 2, An exemplary control bend displacement may be along a predetermined or desired bend line 44 in a manner similar to a slit. The manner of the tongue and the manner of displacement described in the patents and patent applications mentioned above are formed. In the illustrated embodiment, These displacements include a flat region 46 and a slanted transition region 47, As described in the '828 application mentioned above. The flat region is substantially parallel to the entire plane of the sheet material and the transition region extends at an angle relative to the remainder of the sheet material and to the flat region in the manner illustrated in Figure 18A of the '828 application. interconnection. -12- 200904561 The displacement of the control bends is generally formed by displacement in the thickness direction of the sheet. Having the displacement closest to the peripheral portion of the bend line provides an edge and a corresponding opposing face that is constructed and arranged to produce edge-to-edge during subsequent bending of the 2D sheet into a 3D product. Face engagement, It is typically the result of the shear parallel and adjacent to the fold line as described in the '828 application above. The illustrated displacement of the control bend includes a flat region having an elongated portion having a generally semi-circular end. What we will understand is that The actual shape of the flat area changes. E.g, A curve having a plurality of radii can be used to form the elongated portion and the end portion, And oval, Oval, Parabolic and/or other suitable curved shapes can also be used. usually, The shape of the displacement required to control the bending of a particular sheet material may vary depending on the shape and shape of the sheet. In some cases, The benefit of "normalizing" the dimensions of these elongated displacements is to reduce tool costs and simplify design handling and tool repair. E.g, These elongated displacements can be standardized into one. two, Three or more for a specific sheet thickness, The size of the "standard" of a particular type of material and/or other parameters. Now turn to Figure 3, The upper punch assembly 35 includes a plurality of hardened stamping sheets 49, They are arranged to form the displacement of the control bends on the sheet. The upper punch assembly also includes other punches for forming other features on the panel, such as the mount punch 5 1 and the latch punch 53. The illustrated punch assembly can thus be simultaneously formed along a plurality of bend lines to control the displacement and other features of the bend. Includes the stand and/or the latch. of course, The punch assembly can also be constructed to form various features. It is separate from some features -13- 200904561, Or add it up. What we will understand is that Corresponding mold assembly 37 includes several complementary shapes. To assist in the formation of various displacement characteristics of the material. In order to facilitate maintenance services and adjustability, The upper punch assembly has a punch unit 5 4 and the lower mold assembly includes a die unit 5 6 It is removably mounted to a conventional stamping machine 58. These two elements can be used by any suitable institution, It includes, but is not limited to, threaded fasteners (e.g., 'molding fasteners 60'), Dark and/or other suitable structures, And being fastened to the pedestal and/or the upper and lower portions of the press, preferably, The punch unit and/or the mold unit are not hardened, Therefore, the manufacturing cost is cheaper than using hardened steel. Now turn to Figure 4, It shows a stamping or spear insert (: i n s e rt ) 4 9 and corresponding to the lance pocket of the mold block 61. The spear insert and the mold block are preferably, but not necessarily, modular. They can be replaced easily and quickly. And they can be turned and turned, Or end-to-end, Used to present a fresh cutting edge to the cut portion, and in some instances, The spear insert and the mold block can be disposable. As will be explained in more detail below, The modular form of the spear and mold block allows for a cheap and efficient hard work. In detail, The form of the module reduces the amount of machining required to produce a hardened metal and reduces the need to develop a tool design for forming a workpiece into a particular sheet product. Preferably, but not necessarily, The spear and/or the spear pocket are made from pre-hardened stock material. Its honing, The hard rolling and/or electric discharge machining (EDM) is the final shape of the plate including their single compact machines. Steel lance form component facing. It can be inserted into the component that is inserted into the component. -14- 200904561 What we will understand is that Other suitable mechanisms can also be used to form the pre-hardened stock material into the final desired shape. Now turn to Figure 5 and Figure 6, An exemplary spear insert subassembly 63 includes a plurality of spear inserts 49 that are mounted in an exemplary stamping block 65. The stamping block body is then mounted to the upper punch unit 35. The lance inserts are preferably, but not necessarily, removable from the stamping block. The stamping block body is preferably removable from the upper punch unit. The shape and size of the spear insert is substantially compliant with the desired shape of the flat region 46 of the displacement 3 2 of the shift control. Because the spear inserts are subject to greater wear and tear than other components of the system, Therefore, their removable configuration helps them to be repositioned or replaced when the punch unit is on the press. Thereby reducing the downtime of the press, And support regular maintenance. The stamping sub-assembly preferably, but not necessarily, has a substantially modular design. Each assembly corresponds in size and shape to one or more elongated displacements disposed along a bend line. In the illustrated embodiment, The subassembly is constructed to form a displacement that controls the bend, however, What I will understand is that One, Two 'three or more spear inserts can be used to form an amount corresponding to the number of elongate displacements along a bend line. What we will understand is that The number and size of the spear inserts can vary depending on the particular design conditions of the product being formed. In the illustrated embodiment, 'each lance insert is received in an exemplary corresponding stamping pocket recess 67 of the stamping block and preferably, but not necessarily, secured thereto by a suitable fastener Inside. As shown in Figure 7, The spear -15-70 200904561 head insert can be provided with a pawl 68 that engages a corresponding inflatable slat to securely secure the lance insert in position. In the example shown, The swellable gasket is threaded, however, I can confuse that other suitable institutions can also be used. Sandwiched between the stamping block body 65 and the punch unit 54 is an exemplary hardened stamping pad base 72, The lance inserts 49 abut the ram base. As seen in the picture, The stamping pad base may be formed by a flat metal plate. The metal sheet can be easily and relatively inexpensively fabricated or otherwise fabricated. Very importantly, This configuration allows the stamped block 65 to be made of a non-hardened metal. This can further greatly reduce this, Because compared with the traditional hardened stamping block, The non-hardened stamping block can be manufactured in a relatively inexpensive manner and in a shorter period of time, now turning to Figures 8A-8C. When the fastener is fixed and accurately positioned, The inner ends of the lance inserts abut against the insert base such that the lance insert extends from the insert block 65 To form a displacement of the control bend with the desired depth of displacement. Preferably, The pawl 6 8 has a concave contour 74 that allows the inflatable insert to push the spear insert 49 against the punch base 72 and securely secure the punch insert to the punch insert In the recess 67 of the block 65, As shown in Figure 8C. and, The insert 49 is fabricated to allow the stamped sheet to extend outwardly from the stamped block 65 by a minimum amount. This configuration provides greater lateral stability of the spear inserts, Thus minimizing the bending moment of the spear inserts, In order to extend the consumption and reduce the possibility of cracks. What we will understand is that In the example of using a stripper plate, The lance inserts may extend from the rams to the rams of the hard laps. The slabs are extended over the lances to a length of 16-200904561. A thick spear insert extends through the stripper and extends outward therefrom. Preferably, The spear insert and the slidable gasket are constructed to form a detachable insert from the stamping block. In the illustrated embodiment, the slidable spacer 70 has an internal thread 75 and the pawl 68 has a shoulder 77 that is removed from the stamping block block 65 by the lance insert 49 as shown in Figures 8D 8F. In detail, An extraction extractor in the form of a removal bolt 79 can be used to threadably engage the inflatable sleeve 7 to pull the spear insert out of the stamping block. As shown in Figure 8E, The inflatable pad will engage the shoulder 77 and allow the extraction spear insert 49 to apply downward force and remove the spear insert. The picker can further include a rod 81 or other suitable mechanism for applying the force, This is shown by the arrow F in FIG. In the illustrated embodiment, the 'lance insert has a flat end' and the bottom surface of the end is substantially parallel to the remainder of the sheet and/or the punching bed. The benefit of this flat configuration is that it has less damage on the spear insert and extends the life of the spear insert. For example, the wear of a flat spear insert is much less than the wear that occurs on a punch having a sloped bottom. Moreover, the tool at the 'oblique bottom' is generally more expensive to manufacture and more difficult to reshape. Preferably the 'spear insert' is symmetrical in both the vertical direction, Thus, when the edge of the stamping block is ground, the stamping block can be rotated 180 degrees around its vertical axis for the two upper edges (ie, The edges 8 2 ' 8 2 ' ' 82 ' and shown in Fig. 7 are shown. therefore, The life of the spear insert can be doubled or quadrupled' degrees so that the spear is swollen to promote the image (in, The illustrated device is directed to the The bottom of the grinding line is fast and fast, When using horizontal damage, use it 8 2, , , Because -17- 200904561 each spear insert has four trimming edges, And only one shear edge is used. Now turn to Figure 1 to Figure 13. A mold block sub-assembly 8 4 includes a mold block 61 having a removable position within the mold unit 56. In this regard, The mold unit includes a passage 86 for removably receiving the mold block. As mentioned above, The mold unit can be made of non-hardened metal. Thus the passage can be made or machined in a relatively inexpensive manner different from the mold block. on the other hand, The mold block 61 is made of hardened steel and/or other hardened metal. Because the mold block is relatively small, Therefore, the mold block can be quickly processed using standard processing techniques for hardened metals. E.g, The mold block can be fabricated using electrical discharge machining (EDM) or other suitable mechanism. anyway, Only relatively small mold blocks are hardened, And the mold unit accommodating the mold block may be unhardened. therefore, EDM and other relatively expensive hard machining/manufacturing processes are only required when making smaller parts and simple shapes. Therefore, it contributes a lot to the time and money savings. Referring to Figure 12, The construction and dimensions of the mold block 61 are generally compliant with the desired elevation profile that controls the displacement of the bend. In the illustrated embodiment, The mold block includes four mold block recesses 88 that are sized and positioned to mate with four lance inserts 49 to form four displacements on the sheet 33. The spear insert as mentioned above substantially corresponds in shape to the desired flat area 46' of the displacement 32, i.e., the concave inner surface of the desired flat area -18-200904561. The mold block recess 88, on the other hand, substantially conforms in shape to the desired shape of the flat region 46 and the transition region 47, that is, Its outstanding outer surface. It should be noted that In this example, "The inner surface, , And the "outer surface" simply refers to the shape of the displacement, That is, "the inner surface, , Used to indicate the depressed area formed by the spear inserts on the sheet, And "outer surface, , It is then used for the area where the displacement protrudes from the rest of the sheet. The mold block 44 includes a shearing edge 89 that is sized and positioned to cooperate with an adjacent edge of a spear insert 49 to cause the displacement to be substantially parallel to and/or along the bend line. cut. In detail, A small tolerance between the shear edge of the mold block 44 and a corresponding lance insert 49 will cause the flat region 46 of the displacement 32 to be substantially parallel and/or along The bending line 44 is cut, And the opposite edge 9 1 of the concave portion of the mold block and the opposite edge 8 2 of the spear insert 49, The increased tolerance between the two produces a non-shearing displacement of the transition region 47 (see Figure 4). Continuing with reference to Figures 12 and 13, The mold block 44 can have a split body having a shear bar 93 and a joggle bar 95' both made of hardened steel and/or other suitable materials. The shear edge 88 and the recess 8 8 of the mold block are machined into the shear bar. Conventional mechanisms can be used to machine the cutting rod, However, the relatively small size and opening configuration of the shear bar 93 is particularly suitable for Edm processing 'detailed' using a wire-cut EDM or wire-cut discharge machine (WEDM) to form a recess. however, What we will understand is that Hard honing and other suitable mechanisms can be used to machine the shear bar. The relatively small size and simple shape of the splicing bar 95 -19- 200904561 can also be implemented by conventional processing methods. But what we will understand is that The small size and basic shape of the splicing rod can be manufactured by relatively inexpensive processing methods. Both the shear bar and the splicing bar can be manufactured by hardened or honed bar stock stock in w E D Μ or hard honed end cuts. And in the case of a shear bar, the 'tilted surface' can also be formed using WEDM or hard honing to form the slot opening. What I will understand is that Other suitable means can also be used to make the shear bar and the splicing bar. The mold block sub-assembly 84 can include one or more crevices 96, Therefore, different sizes of mold blocks can be used. In detail, The side crevices have channels of different widths in the channel 86. The bottom crevice allows for different depths of the mold block in the channel 86. What we will understand is that The passage 86 can have different lengths of mold blocks. In the illustrated embodiment, The mold block 44 preferably, but not necessarily, has a split body. In this regard, The shear bar 93 and the splicing bar 95 have a cooperating splitting surface 98, 1 〇〇, They are slanted or angled surfaces and are weedged together to secure the mold block within the passage 86. however, This sloping surface is not necessary. E.g, In the embodiment shown in Figures 15A and 15B, Split face 98, The 100 series is substantially vertical 'that is, It is substantially perpendicular to the bottom of channel 86. This vertical construction makes manufacturing simpler and cheaper. In this example, Additional threaded fasteners are used to secure the shear bar 93a to the mold unit 56. In other embodiments, The mold unit passage may be replaced by a receiving portion -20-200904561 02 in that it conforms to the mold block 44a and accommodates the mold block 44a' as shown in Figs. 16 and 17. In this embodiment, The mold unit 56a is machined to accommodate a mold block 44a having a special shape and size. As mentioned above, the mold unit is not made of hardened metal. Therefore, the housing portion 102 can be manufactured relatively easily. On the mold unit 56a. Figure 18 shows another embodiment, Wherein the receiving portion 1〇2b is formed to accommodate two closely fitting mold blocks 6丨b, This structure can be used to form a displacement along two bend lines that intersect at a corner 1 〇 3 . In this example, The shear bar 9 3 b and the splicing bar 9 5 b can be machined to include corresponding mating faces 105, 107, Together, they promote proper positioning of the mold block 44b within the receiving portion 102b. Figure 19 shows still another embodiment, The mold block 61c is linearly segmented. In this embodiment, The mold block is not longitudinally split but has a monolithically formed section 109 having portions on either side of a spear. As shown in the figure, these sections are available at the spear 88. , The termination between the ends of 88' or may terminate in the middle of a spear 88". A threaded fastener or other suitable fastening mechanism as mentioned above can be used to secure the mold block member to the mold unit. In the illustrated embodiment, The threaded fastener 110 cooperates with the fastener recess to removably secure the mold block section. As shown, the fastener recess can be disposed at the intermediate end (e.g., 'recess 1 1 2 ') at the end (e.g., 'recess 1 1 2 '), Or may extend along the section (e.g., 'recess 1 1 2'). In the illustrated embodiment, The fastener 1 12" extends along the length of a section. 'However, it will be appreciated that this recess can extend along a portion of the length of a segment or the entire length of -21 - 200904561. as the picture shows, Gaskets can be used to ' A mold block member is fixed to the mold unit. In operation and use, The displacement of the controlled bends allows the workpiece to be easily taken from the lower mold assembly. It will be understood that A mold ejector can be as desired for its mechanism, For example, the extractor can also be pulled out of the lower mold portion of the punch assembly, and the two pushes can be formed upwards. Downward forming 'or both' now turn to Figure 2 1 A, The machine stamping system 30 d is similar to the upper stamping system 30. However, the manufacturing required to simplify the design of a machine tool (such as sheet metal 3 3 d) is constructed to provide greater efficiency. A blank sheet 3 3 stamping system accepts a single "crush" to the blank board product 3 3 d", As shown in Figure 20. In many respects 'the punch assembly 35 5 d and the upper assembly of the upper punch assembly 3 5 and the lower mold assembly described above in the mold assembly, the spear punch sub-assembly 6 3 ' and the mold block number 糸In an exemplary embodiment of 2 1 A, The upper punch assembly is connected to each other through the sliding column 114 and the slip ring 116 by 3 5 d 37d. Having the punch assembly and the mold assembly relative to each other, although the butterfly assembly is schematically shown in Fig. 21A, the mold assembly is shown. But what we will understand is that the 'slip collar is tied so that the upper punch assembly is 35 d relative to the mold assembly for 3 7 d. What we will be able to understand further is that the machine is stamped but not necessarily in the shape and configuration. however, I am used, Protect it, In the example of the board, This combination. The machine aspect described in the article and in terms of reducing the number of treatments d' can be formed into a sheet in a machine material 37d are similar to 3 7, And above I into 8 4 . In the figure and the lower mold assembly, this reciprocating motion is keyed. The punch assembly and the slidingly receiving slide can be built up -22-200904561 to form the mold assembly moving up and down relative to the punch assembly, The punch assembly can be positioned under the mold assembly. The two assemblies can be arranged to reciprocate horizontally relative to each other, Or the two assemblies can be arranged to reciprocate relative to one another at an angle. The punch assembly 35d includes a stamping block 65d. As will be described below, The stamping block is similar to the stamping block 65 described above, But including several stamping recesses along several bend lines, These recesses accommodate a corresponding number of stamping pieces 49d. In this exemplary embodiment, The stamping block body is segmented and composed of a plurality of members or stamping modules 1 17 . identically, The mold assembly 3 7d includes a mold block 6 1 d, It is similar to the mold block section 109 described above but includes a plurality of lance recesses 8 8d disposed along a plurality of bend lines. In the exemplary embodiment, The mold block is also segmented and composed of a plurality of members or stamping modules 1 19 . however, What we will understand is that The stamping block body and/or the die block body may be one, Two or more modules are constructed. Preferably, The stamped block body and/or the die block body is made of a metal plate having a fixed thickness. therefore, Complex machining operations, For example, crushing and honing, Can be reduced and / or saved, In order to greatly reduce the cost of the stamping block and the mold block. In the exemplary embodiment shown in Figures 2 1 A to 2 1 D, The punch assembly 54d is also constructed to match the mold assembly 56d to effect the operation of shearing a peripheral shape into a blank sheet 3 3 d ' and forming a sheet product 3 3 d". In detail, The punch assembly is provided with a corner cutout 1 2 1 having a shear edge that is complementary in shape to the peripheral shape of the mold block 6 1 d, The corner portion 123' of the cut sheet 33d is cut by -23-200904561 as shown in Figs. 20 and 21A. As we will understand, 'different embodiments can be constructed to have various shapes as needed, Corners and other features are removed from the panel. What we will understand is that The corner cutout block 121 and the mold block body 61d each have a corresponding shear edge. It is thus preferably formed from hardened steel and/or other suitable materials. In different embodiments, The mold block 61d and the corner cutout block 21 are made of the same sheet material. As shown in Figure 2 1 A, The mold block and the corner cutout block are complementary in shape to each other. The corner cutout block can be used by using EDM ’ WEDM, And/or other suitable means to remove the shear bulk material from the mold block material. This configuration reduces material waste and manufacturing processes. therefore, This configuration allows for the fabrication of both mold blocks and corner shear blocks from a single sheet-hardened sheet using EDM or other suitable process. This greatly simplifies the manufacturing process and significantly reduces the amount of waste. When the spear pocket 88d uses EDM, WEDM, And/or other suitable treatments are formed in the mold block 61d, The mold block can be mounted on a platform of the lower mold assembly for 37 d. identically, The corner cutout block 1 2 1 can be mounted on the platform of the upper punch assembly 35d. The crevice sheet 124 can be used to properly separate the corner shear block from the platform of the upper mold assembly. The platform for performing the corner cutout block 121 and the mold block 61d is sufficiently overlapped and the corner portion 123 is cut out from the sheet 33d. The punch assembly 35d is constructed to accommodate the punching piece 49 in the punching piece 65d, The manner is similar to the manner in which the spear insert 49 is mounted within the stamping block 65 as described above. What we will understand is that -24- 200904561 Other suitable methods can also be used to fix the stamping sheet to the stamping block. 〇 As shown in Fig. 21C, The stamping block body may be constructed of one 'two' three or more punching modules 1 17 . It includes a portion of one or more bend lines and/or all of the bend lines. What we will understand is that the 'punch module can be constructed in different ways. The punch module can be secured to the punch assembly 35d by a threaded fastener (not shown) and/or other conventional means. In the example of the stamping block discussed above, The stamped sheet body 6 5 d does not need to be formed with a hardened metal. however, In different embodiments, The punch module can be formed from pre-hardened stock materials. Turn to Figure 2 1 A, The operation and use of the stamping system 30 d will be described. The punch assembly 3 5d was constructed to cooperate with the corresponding mold assembly 3 7d. In different embodiments, The machine press system impacts the sheet to produce a sheet product in a single impact (as shown in Figure 21 A). "Single step" or "single impact" means the action of the machine press system and generally refers to one or substantially one actuation cycle. therefore, The sheet product is formed by using the punch assembly 35 d to emboss or stamp the mold assembly for 37 d. after that, The punch assembly is moved back to an initial position and the press is opened so that the sheet product can be removed during manual processing and/or automated processing. This process can be implemented in a substantially single impact', for example, Actuation of the punch assembly in a single direction can be split into sub-steps. however, Contrary to other systems, The punch assembly is not actuated in a number of large steps. The sheet is placed in the press, The machine pressure -25- 200904561 machine system is actuated to implement a process, And the sheet product was removed. after that, Only limited manufacturing processing is required after this stamping cycle (for example, Polishing). The sheet product does not need to be stamped again to form additional key features. Such as bending lines and the like. The sheet product 3 3 d" may include a plurality of bending lines. Meeting and/or non-committee, And other features of the punch assembly and/or the mold assembly, one or more features, And / or tools. In different embodiments, The feature nodes that can be constructed to produce controlled bends and/or other normalization can be standardized. And/or bent and Other standardized features of the standardization are produced on the stamping block and/or the sheet product, The type of structure, Or other and other embodiments, A set of modules can correspond to the area of the polyline. The other set of modules is the bend line and feature structure. These modules need to be mixed and matched. For example, the cost of the tool is saved and the case is larger. The punch assembly and the mold form a characteristic structure such as a fastening device and an aesthetic decoration in a one-step process. The stamped sheet body and/or the mold block displacement that can be constructed to support the manufacture of the sheet product to produce the features, It defines a standardized bending structure. E.g, Some parts of the intersection of multiple bend lines can be standardized. The mold block can also be constructed to be in the flat feature. Modules can be used to form the construction of the modules by location, It is determined by the specific factors. The construction and use of certain groups of bends that correspond to the intersections of the panels can provide several application benefits for a particular modularity. Although the different actual assemblies can be hard tools and can be in a single sheet, However, these modules allow the -26-200904561 tool to be easily replaced for different design handling (such as different sizes of spear inserts, spear pockets, etc.). Referring to Figure 22, The press system can be provided with a platform 126 that is configured to receive various modules. E.g, The platform may be provided with a module recess 1 28 and/or a module channel 1 30 for standardizing the intersection module 1 3 1 and the bending line module 1 3 3, The manner is the same as that described above and shown in Fig. 18 and other figures. In different embodiments, An ejector 135 can be provided to facilitate removal of the sheet after stamping of the punch assembly (see Figure 22). Because of the relationship between the sheet and the low engagement force of the punch assembly and mold assembly of the present invention, So the ejector does not need to apply a lot of power. The ejector can be a spring ejector, Extractor board, Or other similar assemblies. In a different embodiment, The ejector is formed in a recess in the cavity. In different embodiments, The punch assembly and mold assembly are constructed to form other features.
