The old die is pushed out of the press and onto the die cart. The car takes it to the depositing table on the right.1. 旧模具被推出压机，放到模具车上。大车把它送到右边的寄存台。2. The cart then moves to the table on the left, picks up the new tool, and takes it to the press, where the die loader pulls it into its operating position.2. 然后大车移动到左边的桌子上，拿起新的工具，把它带到压力机上，模具装载机把它拉到它的操作位置。Double-stage Die Cart on Rails (Figure 10-3)轨道上的双级模具车(图10-3)1. The old die is pushed out of the press and onto the die easts empty stage (in this example, the one on the right). The cart takes it to the depositing table on the right.1. 旧的模具被推出了压力机，并在模具东部的空白载物台(在这个例子中的右边一个)。推车把它送到右边的寄存台。2. The cart then moves to the right to position its other stage, holding the new die in front of the press. The loader pulls the die into its operating position. The cart now may take the old die to storage.2. 然后大车向右移动到它的另一个载物台，拿着新的模具在压力机面前。装载机将模具拉入其工作位置。这辆车现在可以把旧的模具送到仓库去了。Two Single-stage Die Carts on Rails (Figure 10-4)轨道上的两个单级模具车(图10-4)1. The cart on the left carries the new die. It moves on rails, approaching the press from the side. The other cart, equipped with a push-pull unit, gets the old die out of the press. It then moves backward on its rails, which run straight to the press.1. 左边的车载着新模具。它在轨道上移动，从侧面接近压力机。另一辆车配有推拉装置，可以把旧的模具从压力机中取出来。然后，它在轨道上向后移动，轨道直接向压力机运行。2. The cart with the new die now moves in front of the press, so that it stands exactly between the press and the cart holding the old die.2. 带有新模具的小车现在在压力机前面移动，所以它正好位于压力机和装着旧模具的小车之间。3. The push-pull unit on the second cart pushes the new tool into the press.3.第二辆小车上的推拉装置将新工具推入压力机。4. The cart that first brought the new die now takes the old die back to storage.4. 最初带来新模具的车现在用来把旧模具放回仓库。Domino (Figure 10-5)多米诺(图10-5)1. A domino system changes dies in several presses in a line simultaneously. First the die carts move in front of their respective presses, each one carrying the appropriate new die. In addition, one empty cart moves to the rear of the last press.1. 多米诺系统的模具在一行中同时按几次键时终止。首先，模具车在各自的冲床前移动，每个冲床上都装有相应的新模具。另外，一个空的推车移动到最后一个压力机的后面。2. Carts and press bolsters are aligned. New dies are then pushed into their presses and, in turn, push old dies onto the carts on the rear of these presses, in a domino effect.2. 小车与压杆对齐，然后把新模具推入他们的压力机，反过来，把旧模具推到这些压力机后面的手推车上，在多米诺效应中。How to Judge the Quick and the Die Change Equipment如何判断快速换模设备Choosing the right equipment that will be the most cost-effective depends on each application and what the goal is for changeover time. Because of the trend toward larger presses, demand has grown for very large, dual-position die carts. Quick die change starts with tool design and pressroom layout, and it is critical that the quick die change tooling coordinates with them.选择最具成本效益的设备取决于每个应用程序以及转换时间的目标。由于冲床越来越大，对大型双工位模车的需求也越来越大。快速换模从刀具设计和压力机房布局开始，关键是快速换模与工装配合。Quick Die Change Equipment快速换模设备 Because of the trend toward larger presses, we have begun building extremely large and dual-position die carts (Figure 10-6)由于更大的压力的趋势，我们已经开始建造非常大的双位模具推车(图10-6)Rolling Bolsters滚动摇枕 Rolling bolsters are suitable when the press table is at ground level. The bolster is moved out of the press to allow easy and safe access to the die. The dies are either exchanged directly on the bolster, which is then pulled back into the press, or there is an exchange with a second bolster that has been prestaged with a new die (see Figure10-7). Rolling bolsters using a rigid chain-pull system can reduce changeover time and allow an almost hands- off quick change operation.当压床在地面时，压床支架是合适的，压头被移出压机，以便容易和安全的接近模具。模具或者直接在支撑台上交换，支撑台上的模具被拉回压机中，或者与第二个支撑台交换，第二个支撑台已经预先使用一个新的模具(见图10-7)。采用刚性链拉系统的滚杆可以缩短换档时间，使换档操作简单易行。Rigid Chain Push-Pull Systems刚性链条推拉系统This push-pull system uses a special-link-design chain (see Figure 10-8). Typically, the die is transferred onto bolster extensions, a die ta
