    • A bending machine having an upper punch containing portion, or beam, and a lower die containing portion, or beam, is modified by incorporating a controlled expandable pressure device whereby the pressure applied to a work material is uniformly distributed throughout the surface of the material. In a first embodiment, the device is mounted in the upper and lower machine portions; in a second embodiment, the device is mounted only in the upper machine portion; in a third embodiment, the device is mounted only in the lower machine portion; and in a fourth embodiment, segmented devices are mounted in the upper machine portion and a single, elongated device is mounted in the lower machine portion.
    • 具有上部冲头容纳部分或梁的弯曲机,以及下模具容纳部分或梁,通过结合受控的可膨胀压力装置来改变,由此施加到工件材料的压力均匀地分布在材料的整个表面上。 在第一实施例中,装置安装在上部和下部机器部分中; 在第二实施例中,装置仅安装在上部机器部分中; 在第三实施例中,装置仅安装在下部机器部分中; 并且在第四实施例中,分段装置安装在上部机器部分中,并且单个细长装置安装在下部机器部分中。
