Abstract

The invention relates to cold sheet punching and can be used to feed flat blanks into a die working area and remove them. after processing. The aim of the invention is to increase the reliability of the device in operation. When the gate moves, the pins spring-loaded in the vertical direction are in constant contact with the copiers. In this case, the pusher lugs deliver the workpiece from the magazine to the working area of the stamp, simultaneously pushing the stamped part. During the return stroke of the gate, the pins, in contact with the copiers, turn the stops with the axis counterclockwise due to the interaction of the stops with the stops and springs fixed on the gate bracket, while raising the stops-pushers above the workpiece. At the end of the return stroke, the pins come out of contact with the copiers, turning the stops with the axis clockwise from the arrow, lowering the stop pushers to the guides to their original position. eo 4 ill.

The invention relates to cold sheet punching and can be used to feed flat blanks into the die working area and remove them after processing.

The purpose of the invention is to increase the reliability of the device.

FIG. 1 shows the device in the initial position, front view; in fig. 2 - the same plan view; in fig. 3 and 4, view A in FIG. 2 (initial a and average b of the position of the pivot beam with limiters when the gate is moving to the right, the last and middle position of the turn of the beam with the limiters when the gate is moving to the left).

The device for feeding and removing flat blanks contains a sliding device 1, kinematically connected with drive 2 and laying, its vertical magazine 3 for blanks 4. The sliding device 1 is attached to the bottom plate 5 of the punch 6 having copiers 7 placed symmetrically on the sides of the punch 6 . On the guides 8 of the slide device 1 there is mounted a gate 9, on the brackets 10 of which the axis is placed. The axis 11 carries the pushers 12 and the pivot stops 13 with the lugs 14, cooperating with the stops 15 fixed on the brackets 10. The stops 13 are connected to the brackets 10 via a spring 16 fixed on the bracket bar 17. The limiters 13 are equipped with pins 18, spring-loaded springs 19.

In the initial position, the upper horizontal surface of the copiers 7 protrudes over the lower end of the pins 18 by the value AND, which is installed depending on the angle of rotation of the stops 13 so that during the slide movement to the left, the pushers 12 do not touch the workpiece fed into the working area.

The device works as follows.

At the initial position, the gate 9 with the axis 11 is in the leftmost position (Fig. 3a), the stops 13 with their protrusions 14 are pressed by the springs 16 to the stops 15 of the bracket 10, the pins 18 under the action of the spring 19 are fully pulled out of the stops 13, and the pushers 12 its bottom plane lies on the surface of the guides 8.

When the gate moves 9 with the axle 11 to the right under the action of the actuator 2, the bottom blank 4 is pushed out from under the feet of the magazine 3, leaning one end into the gate and the other into the rear edge of the push-rod 12. In this case, the pins 18 interact with the inclined the surface of the copiers 7 are pushed into the stops 13, compressing the spring 19, and in this position slides along the horizontal surface of the copiers 7 (Fig. 3b).

At the end of the slide gateway 9 to the right, the pins 18 jump off the horizontal surface of the copiers 7 and under the action of the springs 19 are pushed out of the stops 13, resting against the vertical surface of the copiers 7 under the action of the springs 16 (Fig. 4e). In this case, the pusher lugs 12 with their front edges push the stamped part out of the working area of the stamp, at the same time delivering the next billet from the store 3 to the stamp.

During the return stroke of the gate 9 with the axis 11 to the left, the pins 18, resting the lower end on the vertical surface of the copiers 7, turn the stops 13 and the axis 11 counterclockwise, stretching the spring 16 and raising the pusher lugs 12 above the workpiece 4 until pins 18 do not begin to slide along the horizontal surface of copiers 7 (Fig. 4 g.

At the end of the stroke to the left, the pins 18 come out of contact with the copiers 7 and under the action of the springs 16 rotate the stops 13 and the pivot axis clockwise, lowering the pusher stops 12 on the guide rollers 8 to the initial position (Fig. 3a).

Then the cycle repeats.

Installation of beam turn stops with the ability to interact with the stops

30 and fuzins, mounted on the gate brackets, also supplying the stops with spring-loaded pins, which interact with the stamp copiers, increase the reliability of the device when it is fed from the magazine to the stamp and simultaneously removed from the stamp of flat blanks.
