用于对模具或工具进行加热的装置和方法
摘要：
本披露涉及一种用于以其一个作用表面来对毛坯进行压花/压制的工具，该工具具有一个具有多层的堆叠，该堆叠包括在该作用表面处的一个顶层(25)，该顶层在压花/压制的过程中被加热，其特征为一个空腔(47)，该空腔是在该堆叠中的两个层之间、如从该作用表面所看到的在该顶层的下方被限定的，该空腔在该作用表面的一个较大部分的下方延伸并且至少部分地填充有一种流体。
摘要（英）：

The disclosure relates to a method and a tool for embossing/pressing a blank with an active surface. The tool has a stack of layers including a coil carrier layer (21) with a coil, and an electrically conductive top layer (25), adjacent to the active tool surface. The top layer is heated during embossing/¬pressing by feeding power to the coil. A cavity (47) is formed between two layers in the stack beneath the top layer (25) as seen from the active surface, the cavity extending beneath a greater part of the active surface and being filled with a fluid, such that applied pressure over the active surface is equalized while the top layer (25) is heated.
