    • PURPOSE: A cross head is provided which has a die able to be operated under high pressure with a simple structure, to remove eccentricity automatically. CONSTITUTION: A cross head for extruding a cable or a tube is provided which can control eccentricity during extrusion. A metal bar(18) having built-in thickness measuring sensor and heater(19) is installed between a body(11) and a die(13), and if eccentricity is occurred in the cable or tube in extrusion, the senor senses the eccentricity and the metal bar is expanded thermally with a fixed temperature by supplying electricity to the heater. The thermally-expanded metal bar is extended in its height and pushes out the die.
    • 目的:提供十字头,其具有能够在高压下以简单的结构操作的模具,以自动地去除偏心。 构成:提供用于挤出电缆或管的十字头,其可以在挤出期间控制偏心。 具有内置厚度测量传感器和加热器(19)的金属棒(18)安装在主体(11)和模具(13)之间,并且如果在挤出时在电缆或管中发生偏心,则传感器感测 偏心率和金属棒通过向加热器供电而以固定的温度热膨胀。 热膨胀的金属棒在其高度上延伸并推出模具。
