    摘要: Disclosed is a method to punch a plurality of holes of fine diameter d on brittle material at fine intervals α. The method includes the steps of forming at least two holes including a hole of fine diameter d at intervals A, each of which is at least two times the fine interval a, by the use of a punching die, and punching holes between the previously punched holes at intervals A so that the distance from the punched holes of diameter d measures at least the distance corresponding to the fine interval α, without removing the punches used to form the holes in the previous step. The die comprises a plurality of punches having punching tips, a punch plate for holding said punches, a die including a plurality of fine holes of prescribed diameter for inserting and removing the punching tips of said punches, and a stripper disposed between said punch plate and said die for holding the tips of said punches and peeling brittle material to be punched off said punch when removing said punches from said die. A plurality of punches is composed of at least two groups of punches in which the positions of the apexes of the respective tip portions differ from each other.

    摘要: There is provided a die structure having a simple configuration in which a damage of thin plate-like material (workpiece) caused by a continuous punching of holes while punctured chips are being adhered to the extremity end of the punch is prevented and the punctured chips are prevented from being raised as the punch is lifted up to close the punctured punch holes. The punch P pierces into the resilient film 3. The pierced hole of the resilient film 3 punched by the punch P is kept at a state in which it is extended instantly, torn out, removed and resiliently expanded, and in turn when the punch P is pulled out of it, it is resiliently shrunk into a smaller shape than that of the punch P. The punctured chip (c) adhered to the extremity end of the punch P is engaged with the resilient film 3 (more practically, an edge of the punctured hole to be shrunk) which is shrunk when the punch P is raised and then drops.

    摘要: A punch apparatus for punching hole patterns in thin sheet material. The apparatus includes a housing having a liquid-cooled cavity (46) therein; a coil (58) mounted in the liquid-cooled cavity; a driver disk (48) made of a highly conductive material mounted in the liquid-cooled cavity, the driver disk mounted adjacent to the coil; a driver button (49) located outside of the liquid-cooled cavity but in communication with the driver disk; and a punch element (32) for perforating thin sheet material aligned with the driver button. Finally, the apparatus includes an electrical source for energizing the coil with a pulse of electrical energy for generating flux linking the driver disk and the coil to repel the driver disk from the coil, there­by translating the driver button and the punch element, causing the punch element to perforate a thin sheet of material.

    摘要: A booster for the cusion-knockout mechanism (62) associated with the slide (61) of a press-machine (60) serves to stably hold down a work plate such as a printed board and the likes while performing a cushioning operation during a pressing or punching stroke and serves to knock the work plate out from the punches (68) after the pressing stroke has been completed. The booster is connected to a hydraulic actuation chamber (64) of a cushion cylinder (63) provided in the slide of the press-machine by valve means (27) comprising a valve body portion (44) within a valve casing (22) and a knockout actuator (28) which is fixedly secured to the valve casing so as to perform the valve opening operation of the valve means. The valve means are adapted to push a valve body toward the valve closing side by the resultant force obtained from a spring force of a valve closing spring (31) and the pressure in the valve chamber and to push the valve body toward the valve opening side by a pressure in a back pressure cylinder (40), which is connected to the valve chamber so that the force which pushes the valve body toward the valve closing side is decreased by the body toward the valve closing side is decreased by the back pressure applied to the valve body.
