In metalforming,the geometry of the workpiece is established entirely or partially by the geometry of the die.In contrast to machining processes,ignificantly greater forces are necessary in forming.Due to the complexity of the parts,forming is often not carried out in a single operation.Depending on the geometry of the part,production is carried out in several operational steps via one or several production processes such as forming or blanking.One operation can also include several processes simultaneously(cf.Sect.2.1.4).
During the design phase,the necessary manufacturing methods as well as the sequence and number of production steps are established in a processing plan(Fig.4.1.1).In this plan,the availability of machines,the planned production volumes of the part and other boundary conditions are taken into account.
The aim is to minimize the number of dies to be used while keeping up a high level of operational reliability.The parts are greatly simplified right from their design stage by close collaboration between the Part Design and Production Departments in order to enable several forming and related blanking processes to be carried out in one forming station.
Obviously,the more operations which are integrated into a single die,the more complex the structure of the die becomes.The consequences are higher costs,a decrease in output and a lower reliability.
模具類型
模具的類型和模具之間零部件的密切相關(guān)運(yùn)輸是根據(jù)成形步驟、預(yù)算的部件的尺寸、要生產(chǎn)的部件的生產(chǎn)量來確定的。
大型鈑金零件的生產(chǎn)幾乎完全采用單套模具來實現(xiàn)的。典型零件可在汽車制造、國內(nèi)家電業(yè)以及散熱器的生產(chǎn)中找到。適當(dāng)?shù)霓D(zhuǎn)移系統(tǒng)，例如真空抽吸系統(tǒng)，可以使雙動模安裝在一個足夠大的安裝面上。例如，用這種方式可以使汽車左右車門在一個工作行程中一起成形。（參考圖4.4.34）。
尺寸大的單套模具需安裝在大型壓力機(jī)上。部件從一個成形點到另一個成形點的運(yùn)輸是機(jī)械化地執(zhí)行的。工人或機(jī)器人可以使用與單工序壓力機(jī)一前一后安裝的沖壓線(對比圖4.4.20與 4.4.22)，同時，在大型多工位壓力機(jī)上，系統(tǒng)還配備了夾鉗軌（如圖4.4.29）或交叉抽吸系統(tǒng)（如圖4.4.34）來運(yùn)輸部件。
多工位轉(zhuǎn)換模是用于小型和中型零件的大批量生產(chǎn)（如圖4.1.2）。它們由幾個安裝在同一個基準(zhǔn)平面上的單工序模具組成。金屬板料的送進(jìn)主要以機(jī)械手運(yùn)送的方式，也可以人工地從一個模具運(yùn)到另一個模具。如果這部分的運(yùn)輸自動化，那么此時的壓力就稱為轉(zhuǎn)換壓力。在大板料轉(zhuǎn)換沖壓線上，最大的多工位轉(zhuǎn)換模要與單工序模具配合使用（參考圖4.4.32）。
