摘要： The press brake punch holder has a main housing adapted for attachment to the ram of a press brake. A pair of mating wedge strips are disposed within the housing, the lower wedge strip being slidable with respect to the upper wedge strip. A U-shaped channel is disposed between two flanges depending from the side walls of the main housing, the exterior surfaces of the flanges being beveled, the U-shaped channel being slidable vertically between the flanges. A bolt extends through each upper wedge, a slot defined in each mating lower wedge, and a slot defined in the bottom of the housing, in order to thread into holes defined in the U-shaped channel. A support member having a cross shape in cross section depends from the U-shaped channel. A plurality of clamps are bolted into the ends of the side arms of the support member, the clamps being spring biased to clamp the shank of a punch between the clamp and the lower leg of the support member. The upper edge of the clamp is beveled to mate with the beveled edges of the flanges. The lower wedge strip may be pulled along its longitudinal axis, either by mechanical, electrical or hydraulic power, the bolts pulling the U-shaped channel vertically upward, causing the upper edge of the clamps to slide up the side of the flanges, thereby opening the clamps simultaneously and releasing the punch.
摘要翻译：压力制动冲头保持器具有适于附接到压力制动器的压头的主壳体。一对配合楔形条设置在壳体内，下楔形条可相对于上楔形条滑动。 U形通道设置在从主壳体的侧壁悬垂的两个凸缘之间，凸缘的外表面是倾斜的，U形通道可在凸缘之间垂直滑动。螺栓延伸穿过每个上楔形物，限定在每个配合的下楔形物中的狭槽和限定在壳体的底部中的狭槽，以便螺纹连接到限定在U形通道中的孔中。横截面为十字形的支撑构件取决于U形通道。多个夹具被螺栓连接到支撑构件的侧臂的端部中，夹具被弹簧偏压以将夹具的柄夹紧在支撑构件的夹具和小腿之间。夹具的上边缘倾斜以与法兰的斜边缘配合。下楔形条可以通过机械，电动或液压动力沿其纵向轴线拉动，螺栓将U形槽垂直向上拉动，使得夹具的上边缘沿凸缘的侧面滑动，从而打开夹具同时释放冲头。

摘要： A sheet material blank preformed to a standardized dimension and configuration for forming the digits zero through nine for signs. The preferred embodiment of the blank is made from an opaque, flexible sheet material having pressure sensitive adhesive applied to the backside and a release liner. The key feature of the blank is its rectangular outer dimension and two rectangular apertures of equal area centered within said outer dimension so as to define a pair of elongated legs of equal width integrally bridged by three horizontal elongated members of a width equal to the width of said pair of legs. The blank thus defines a figure having parallel and linear edges resembling the digit eight. The second key feature of the blank is linear indicia provided on the release liner which aids the consumer in creating the desired digits from the blank. Predetermined rectangular areas are designated on each of the elongated legs and elongated horizontal members whereby a rectangular area may be selectively removed by making a cut along a pair of the linear indicia to form a digit different from the blank. Alternately, the rectangular outer dimensions and the rectangular apertures can have round corners.
摘要翻译：片材坯料预成型为标准尺寸和构型，用于形成数字零至九的符号。坯料的优选实施例由具有施加到背面的压敏粘合剂的不透明柔性片材和剥离衬垫制成。坯件的关键特征是其矩形外部尺寸和两个相等面积的中心在所述外部尺寸内的矩形孔，以便限定一对相等宽度的细长支腿，该长条状的整体由三个水平细长构件桥接，宽度等于说双腿因此，空白限定了具有类似于数字八的平行和直线边缘的图形。空白的第二个关键特征是在释放衬垫上提供的线性标记，有助于消费者从空白中创建所需的数字。在每个细长腿和细长水平构件上指定预定的矩形区域，由此通过沿着一对线性标记进行切割可以选择性地去除矩形区域，以形成与坯件不同的数字。或者，矩形外部尺寸和矩形孔可以具有圆角。
