(54) DEVICE FOR SUBMITTING BLACKBOARDS

one

The invention relates to the field of punching automation and can be used to feed piece blanks into die forging (for example, embossing).

A device for supplying piece blanks to the working area of the press is known, comprising a gate located on the base, receiving a return-1 access movement in a horizontal plane from the actuator " link, and a clamp installed with simultaneous displacement with the gate and translational movement relative to the latter along the direction of its movement.

A disadvantage of the known device is that it cannot be used for feeding in stamps, in which, according to the working conditions, nodes cannot be used to base the blanks. The use of moving base units complicates the design of the dies and makes it difficult to remove stamped parts from them.

In the proposed device, this disadvantage is eliminated by the fact that the device is equipped with an undercut: There is no lock lock installed on the base, which can be rotated under the action of the cam provided on the clamp and interacting with the gate in its K1 extreme position in the working area, interacting with the slider and clamp, while the lock is installed on the base with the possibility of adjusting movement along the gate motion.

The drawing schematically shows the proposed device.

The device contains placed on the base 1 stepped gate 2, receiving (reciprocating movement in the horizontal plane from the drive link 3, and clamp 4 mounted on the slide 5, on which the cam 6 is fixed. To fix the extreme position of the gate in the working zone on the base A swinging spring-loaded latch 7 is installed, one arm of which interacts with the supporting end 8 of the gate and the other with the cam 6. The movement from the drive link to the gate and clamp is transmitted by means of spring-loaded stop 9 and fixed stops 10 and 11. There is a stop 12 on the prizhime, which interacts with the limit switch 13 in the presence of the workpiece under the clamp and passes by it in the absence of the workpiece, which makes it impossible to activate the backward movement of the gate and interrupts the automatic operation of the device. In addition, a fixed stop 14 is placed on the base of the device, determining the outcome

The position of the clamp, and on the adjustable latch holder 15 - at the OP 16, which determines the extreme position of the slide valve in the working area.

U | Stroystvo works as follows. In B (rem of his own; when moving, the slide in front of the end of the end moves the workpiece, which is under the clamp behind the spring-loaded canted stop 17, to the working area for oi6ipai6oiTKH tool 18. At the same time, the back end of the slide makes the next workpiece 20 out of the magazine 19 and feeds her intermediate position for spring-loaded yinoip 17.

Together with the gate, which is driven by the drive link with the help of the stop M, yiHoip 10 moves the pressure to the working zone. At the time of the stop of the gate, the adjustable stop 16 by the supporting end 8 of the gate opens the spring lock, and the workpieces and the presses are also stopped. In the presence of the workpiece under the clamp. His emphasis 12 switches from to. power limit switch actuator (not shown) of the device on the reverse stroke. The return stroke begins to perform the clamp, receiving movement from the stop 9 mounted on the drive link. Since the gate is zafi1K1Sirov1N, it is at this time still, and the clamp presses the workpiece 21 to the front end of the gate. This ensures accurate installation of the workpiece 21 in the work area. After the release of the clamp from contact with the workpiece he

removes the locking cam from the ribs with the BOTTOM cam, and the last one also moves to its original position behind the magazine with its rear end and behind the spring-loaded stop 17 with the front end, leaving the workpiece 21 in the working area. The clamp comes into contact with the workpiece 20, which is located at an intermediate position, and stops by the stop 11. After this, the cycle is repeated.
