摘要:
A die (613) is supported in a die holder (18, 381, 581) such as a frame or an adapter supported in a frame such that it is operational use in a material deforming operation. One or both of the die (613) and the die holder (18, 381, 581) have at least one gas passage (683, 30, 31) which is substantially closed by at least part of the die. Gas such as pressurised air is directed into an end of the gas passage opposite the die via a hose connected to a gas source. If the die is broken or loose leak paths are available for the escape of gas past the die to or from atmosphere. A pressure sensor (40) connected to the hose detects the change in pressure of the gas and the magnitude of that pressure is used to determine the die condition. Alternatively a flow rate sensor (40) is used to detect a change in the flow rate of the gas in order to determine the condition of the die.
摘要(中):
模具(613)被支撑在诸如框架或支撑在框架中的适配器的模座(18,381,581)中,使得其可用于材料变形操作。 模具(613)和模具保持器(18,381,581)中的一个或两个具有至少一个气体通道(683,30,31),其通过至少部分模具基本封闭。 诸如加压空气的气体通过连接到气体源的软管引导到与模具相对的气体通道的端部。 如果模具破裂或泄漏的泄漏路径可用于将气体从模具中逸出或从大气排出。 连接到软管的压力传感器(40)检测气体的压力变化,并且使用该压力的大小来确定模具状态。 或者,流量传感器(40)用于检测气体的流速的变化,以便确定管芯的状态。
