    1363485 Electro-erosion ATELIERS DES CHARMILLES SA 1 Oct 1971 [22 Oct 1970] 45703/71 Heading B3V An electro-erosion apparatus includes a base platen 2, a movable platen 5 slidable in a frame 6, 7 over a first distance and a work or electrode carrier 8 supported by guide means 9 or one of the platens 2, 5 and movable with respect thereto through a second shorter distance under the control of a servomechanism 12. In one embodiment, Fig. 1, the movement of a carrier 8 for the electrode 4 is controlled by a servomotor 12 in accordance with the erosion gap voltage. The shaft 21 of the motor 12, fixed to the carrier 8, is connected by a crank 14 to a frame 15 which is in turn connected by cranks 16 to screws 17 engaging nuts 19 on the platen 5. Guide rods 9 are positioned between the carrier 8 and its supporting platen 5 which is movable by jacks (not shown). Dielectric fluid is circulated to the gap by a pump 2a. In another embodiment (Figs. 3 and 4, not shown), the workpiece (1), e.g. a press die, is positioned on the carrier (8) carried by needle bearings (35-38) mounted on eccentrics (39-42) positioned at the ends of parallel shafts (33, 34). The piston-rod (46) of a pivotable jack (43) is connected to a crank (45) on the shaft (33), which is coupled to the other shaft (34) by linkage (47-49). Movement of the piston-rod (46) by the servomechanism causes the carrier (8) to be moved vertically. A platen (5) carrying the electrode (4) is movable by a piston and cylinder (27, 28<SP>1</SP>). A platen (2) on which the carrier (8) is mounted is movable horizontally to facilitate the positioning of the workpiece. In a further embodiment (Figs. 5 and 6, not shown), the workpiece carrier (8) is mounted on a frame (57) which is movable on inclined surfaces (64) by a jack (59) controlled by the servomechanism. Air cylinders (65) are positioned between the platens (2, 8) to compensate for differences in weight supported by the platen (8). The electrode is formed of two parts (4a, 4b).

    专利说明:

    The invention relates to devices for electroerosive processing of large-sized parts, for example, matrix presses for stamping the wings of car bodies.
    Known are devices for processing large-sized parts, comprising a generator, a dielectric fluid supply system, two parallel fixed plates mounted on the frame, one of which is movably mounted with an intermediate plate, which forms the holders of the workpiece and electrode C] with the opposite plate.
    A disadvantage of the known device is a low speed due to the fact that one and one same drive pre- "is assigned to the mounting rail Nia displacement (m and more) and of displacement within a few centimeters.
    The aim of the invention is to increase productivity by 35 reducing the processing time by the drive of working displacements when adjusting the erosion gap.
    The goal is achieved by the fact that in the proposed device one of the plates2 is mounted on the frame with the ability to move from the individual drive and with the possibility of fixing at various distances from the fixed 6 plate.
    This allows installation and working movements by moving various plates.
    To increase accuracy, the drive plate moves the intermediate plate in contact with it at several points.
    The drawing shows the described device.
    The workpiece 1 lies on the plate 2, which is the bottom of the bath, the movable plate 3 moves between two parallel racks 4 and can be fixed at any point. Under the movable plate 3 is moved by spindles located in the racks 4, the intermediate plate 5, suspended on a movable plate 3, carries the electrode tool 6. Both plates are connected by rods 7, mounted in the plate 5. The plate 5 is hollow and also serves to accommodate the regulator 8 the movement of the plate 5 relative to the plate 3.
    The device works as follows **. Time.
    16516
    The workpiece 1 is precisely fixed on the fixed plate 2, then the “movable plate 3, with the help of the drive located in the racks 4, is moved until the electrode-tool is sufficiently close to the workpiece 1 to be processed. At this moment, the plate 3 is fixed relative to the plate 2 '; After this, the electrical discharge processing of the workpiece occurs. All movements of the electrode- (the instrument is produced by moving the intermediate plate 5. '.............
    Thus, the productivity of the processing process increases.
