shop 18 for stamped decks. The carriages 50 are located near a two-position driving turntable 21, the support plates 47 of the device 9 for lifting die blocks are lowered.

On command from system 1 control. The working environment, for example, air, is fed into the battery (receiver),

26, and from it through the throttle DR, the hole "b" and grooves "a" with sealing elements 25 in the die plate 12, the cylinder body 22 of the device 6 disclosure of die blocks. The top plate of the die unit 3 smoothly rises and presses against the press ram: 2, The die unit 3 is opened And ready to go. On command from the control system 1, the ruler 63 with electromagnets 67 tongs 14 of the manipulator 13 moves to the receiving position — dispensing the device. 16. by piece dispensing and storing the blanks or stamped parts. Tines 14, falling, lay electromagnets 67 on the workpiece held by the vacuum tongs 88 and, moving the guides 85 with the housings 87 vacuum tongs 88, compress the springs 86, straighten the workpiece and capture it. The stiffness of the springs 66 is higher than the stiffness of the springs 86. Then the ruler 63 moves to the working position of the press 2, tongs 14, lowering and rising, puts the workpiece to the working position and moves to the receiving-dispensing position for the next workpiece. There is a stamping of the workpiece. On command from the control system 1, the slide of the press 2 drives the upper plate of the die block 3, Plungers 24, moving in the guides 23 relative to the cylinder bodies 22, compresses the air, partially squeezing it through the check valve KO into the accumulator 26. - th unit 3 preloaded to the slide of the press 2, and the battery 26 is under pressure and is fed from the pressure line. Turns on the electric motor 46 of the device 19 for collecting and disposing of waste and rotates the drive roller 38, the Closed flexible tape 45 mounted on the lead 38 and the driven 42 rollers takes out the cut

waste in the shop container (not shown). When a signal is received from the system

1 control about the disclosure of the die block 3, the manipulator 13 moves the ruler 62 with electromagnets 67

5 grips 14 on the working position of the press: 2, tongues 14 are lowered, placed on the workpiece by electromagnets 67, moving on the guides 65, compressing the springs 66, seizing the bezel and lifting. On the working position of the press 2 electromagnets 67 ruler 63, holding the workpiece. There is a loading of the strain of the next block by the next billet.

15 When using multi-layered straps for punching the strip, the waste collection and disposal device 19 can carry stamped blanks into a hopper (not shown), and electro2 magnets 67 of the ruler 62 take and remove 2 wastes from the working position of the press. Since the strips do not go to failure, then for the second transition, operations similar to those with piece blanks are performed, but each electromagnet 67 carries its own cut blanks separately and transmits them to the corresponding vacuum

30 grips 88 devices 16 single delivery and storage of blanks or stamped parts.

Line 63 with electromagnets 67 moves to the receive-issue position

hello There is a seizure of the workpiece. Then a ruler 62 with electromagnets 67 holding the cut-out workpiece is placed at the pick-up position of the transfer · *. The tongs 14 are lowered, moving the guides 85 with the housings 87 of the vacuum tongs 88, compressing the springs 86 ”. The cut-up blank is caught by the vacuum tongs 88.

When moving the grippers 14 of the manipulator 13 to the working position of the press 2, the cut blanks are stored in the store 18 for stamped parts, which serves as an intermediate storage device, and

The cylinder 70 drive vertical movement lowers the carriage 68. When approaching the foot of the cut blanks in the store 18 vacuum grippers 88 with housings 87 on the rails 85 begin to move relative to the housings 84, compressing the springs 86, straighten the workpiece; adjustable stops 82, mounted in housings 81, abut against the cut-out workpiece, level sensors 83 are triggered _but The blanked billet® is reset by the cylinder 70 of the vertical movement actuator lifting the carriage 68 to the uppermost position, in which 74 rod actuators turn the cylinder 71 through the gear 75 and the transfer 77 with a flexible coupling rotate the lever 71. The cylinder 80 rail cylinders The rotational drive of the swivel rod 78 rotates it and locates the vacuum grippers 88, the adjustable stops 82 and the level sensors 83 down, but already above the shop 17 with blanks. The cylinder 70 drive vertical movement lowers the carriage 68. When approaching the stack of workpieces vacuum grippers 88 with housings 87 on the rails 85 begin to move relative to the housings 84, compressing the springs 86 until an adjustable stop 82 approaches, the level sensors 83 are activated, the workpiece is gripped. The cylinder 70 drive vertical movement starts to lift the carriage 68. The spring 86, unclenched, move the housing 87 vacuum Grippers 88 on the rails 85 at different distances and bend the workpiece, it is separated from the foot. In the extreme upper position of the carriage 68, the rod-rails 74 of the cylinder of the rotational drive of the lever 71 are actuated, which rotate the lever 71 to the initial position. The workpiece captured by the vacuum tongs 88 is in the pick-up position. The cycle is repeated until the complete production of the store 17 with blanks.

Then, on command from the control system 1 in the battery 26, the pressure is released, the punching unit 3 is closed. The rods 26 of the drive cylinders of the device 8 for clamping the lower plates of die blocks remove wedges 27 ”The drive motor 53 of the drive 10 moves the die blocks and, by rotating the sprockets 56 installed in the supports 55, and through the flexible one. bond (chain) 61, double asterisks
