    • A system for preparing a self-hardening casting mold including a mass of sand which contains an organic binder and which has a pattern-contact layer having a surface for contact with a pattern disposed in a flask. The pattern defines a cavity into which a melt is poured to produce a cast product. The mold further includes a mass of ceramic balls placed on the pattern-contact layer of the sand mass. The system includes a temperature adjusting device for regulating the temperature of the mass of ceramic balls prior to introduction thereof into the flask, so as to control the hardening rate of mass of sand in the flask, a separating device operable on a mixture of sand and ceramic balls obtained from the mold after the cast product is produced by the mold with the pattern removed. The separating device separates the ceramic ball from the sand, and supplies the ceramic balls to the temperature adjusting device. The system further includes a sand reclaiming device for treating the separated sand to be reclaimed for preparing another casting mold.
    • 一种用于制备包含大量沙子的自硬化铸模的系统,所述砂含有有机粘合剂,并且具有图案接触层,所述图案接触层具有与设置在烧瓶中的图案接触的表面。 该图案限定了将熔体注入其中以产生铸造产品的空腔。 模具还包括放置在砂体的图案接触层上的大量陶瓷球。 该系统包括温度调节装置,用于在将陶瓷球的质量引入烧瓶之前调节陶瓷球的温度,以便控制烧瓶中砂的质量的硬化率,分离装置可在砂和 铸造产品后由模具获得的陶瓷球通过模具除去图案来生产。 分离装置将陶瓷球与砂分离,并将陶瓷球供给温度调节装置。 该系统还包括用于处理待回收的分离的砂以制备另一铸造模具的砂土回收装置。

    • A machine vise for clamping a workpiece between a stationary jaw fixed to a body, and a movable jaw provided on a movable member which is moved relative to the body by a rotating motion of a feedscrew member which is rotatably supported by a support portion formed on one of the body and the movable member, the feedscrew member having an externally threaded portion engaging an internally threaded member provided fixedly to the other of the body and the movable member. The feedscrew member includes a radially outwardly extending flange portion which prevents the feedscrew member from moving in the axial direction relative to the support portion, due to a reaction force which is produced upon clamping of the workpiece. The machine vise includes a strain detector device disposed between the support portion and the flange portion of the feedscrew member, for detecting an axial force which is exerted on the support portion via the flange portion and the detector device due to the reaction force. The detector device generates an output signal that indicates the axial force and consequently a clamping force of the workpiece.
    • 一种用于将工件夹持在固定到主体上的固定夹爪之间的机器虎钳和设置在可移动构件上的活动夹爪,所述可动夹爪通过由可形成在支撑部分上的支撑部分可旋转地支撑的进给螺杆构件的旋转运动而相对于主体移动 所述主体和所述可动构件中的一个,所述进给螺旋构件具有接合固定地连接到所述主体和所述可移动构件中的另一个的内螺纹构件的外螺纹部分。 进给螺旋构件包括径向向外延伸的凸缘部分,该凸缘部分由于在夹紧工件时产生的反作用力而防止进给螺旋构件相对于支撑部分在轴向方向上移动。 机器虎钳包括设置在支撑部分和进给螺杆构件的凸缘部分之间的应变检测器装置,用于检测由于反作用力而经由凸缘部分和检测器装置施加在支撑部分上的轴向力。 检测器装置产生一个指示轴向力并因此产生工件夹紧力的输出信号。
