卷制法兰的模具接触工件是用来做什么的?

  卷制法兰是采用开式卷制法兰锻造而成的一种沿其长度方向连续变形的棒材。它通常用于将一块原材料加工到合适的厚度。一旦合适的厚度达到合适的宽度,就可以逐步实现。

  Roll flange is a kind of bar which is forged by open roll flange and continuously deformed along its length direction. It is usually used to process a piece of raw material to a suitable thickness. Once the appropriate thickness reaches the appropriate width, it can be achieved gradually.

  该工艺材料的渐进浓缩使用凹形来打开模具。这个过程被称为边缘加工,因为滚动法兰通常在工件的两端进行。填隙是一个类似的过程,利用凸形模锻法使零件变薄。这些加工件进一步轧制和翻边,为锻造工艺做准备。在这个过程中,有一些缺点,大多数是由于工件与模具接触了一段时间。操作步骤的数量和长度是一个耗时的过程。

  The progressive concentration of the process material uses a concave shape to open the mold. This process is called edge machining because rolling flanges are usually performed at both ends of the workpiece. Shimming is a similar process, in which the parts are thinned by convex die forging. These workpieces are further rolled and flanged in preparation for the forging process. In this process, there are some disadvantages, most of which are due to the workpiece contacting with the mold for a period of time. The number and length of steps is a time-consuming process.

  由于模具与工件的接触和模具的传热作用比周围环境的传热作用大得多,因此轧后法兰件的冷却速度较快。当工件冷却时,滚动法兰变得更强,韧性更差,如果继续变形,可能会导致开裂。因此,通常使用加热模具来减少热损失,促进表面流动,并制定生产细节和公差。

  Because the contact between the die and the workpiece and the heat transfer effect of the die are much greater than that of the surrounding environment, the cooling speed of the flange after rolling is faster. When the workpiece is cooled, the rolling flange becomes stronger and the toughness is worse. If the deformation continues, it may lead to cracking. As a result, heating dies are often used to reduce heat loss, promote surface flow, and develop production details and tolerances.
