(54) DEVICE FOR SUBMITTING STRIP AND TAPE MATERIAL TO THE STAMP WORKING ZONE

The drawing shows the proposed device, a General view.

The device for feeding the strip and tape material into the working zone of the stamp contains a feed carriage 2 installed on the bottom plate 1, a carriage 2 on which the wedge supports 3 are fixed, interacting with the wedge 4, made on the wedge 5 mounted on the top plate 6 of the stamp . The wedge 5 is spring-loaded by the spring 7 in the direction opposite to the direction of movement of the material 8. The feed carriage .2 is made in the form of a plate and a plate 9 is mounted on it, connected to the bottom plate by guide-rings 10 and screws 11 with springs 12. The feed carriage 2 spring 13. In the plate 9 a spring-loaded sponge 14 is installed, interacting with the material 8. On the bottom plate 1 a stand 15 is mounted, in which a spring-loaded rod 16 (spring buffer) is mounted. At the end of the rod 16, an adjusting nut 17 is installed. A groove is made in the plate of the feeding carriage 2

18, the walls of which interact with the latch, made in the form of a punch rod mounted on the upper plate 6

19, spring loaded 20.

On the bottom plate 1, a matrix 21 is installed and two shoulders levers 22 and 23 are fixed-hinged, on which rollers 24 and 25 are fixed, interacting with plate 9, and rollers 26 interacting with pushers 27. fixed on the top plate 9, a spring-loaded clamp 28 is installed. A longitudinal grooves are made in the plate 9 and in the feed carriage 2 to enable the clamp 28 to close with the die 21.

The device for feeding the strip and tape material into the working area of the stamp works as follows.

The material 8 is placed between the plate 9 and the feeding carriage 2 and is clamped by the tube 14, i.e. between the feeding carriage 2 and the plate 9.

When the upper plate 6 moves downward, the wedge 5 acts with wedge lugs 4 on the wedge supports 3 and moves the feeding carriage 2 with material 8 to the left to the feeding step, compressing the spring 13.

At the end of the feed step, the presser 28 presses the material 8 to the die 21, and the pusher 27 acts on the rollers 26. The two shoulders levers 22 and 23 rotate around the axes, the rollers 24 act on the plate 9, which moves upward along the guide columns, compressing the springs 12. Material 8 is released. Upon further downward movement of the plate 6, the wedge protrusions 4 emerge from the interaction with the wedges by the supports 3 and the feed carriage 2 is moved to the initial position by the action of the spring 13. When moving the feed carriage 2, the plate 9 is in the upper position. A spring-loaded rod 16 cm thickens the impact of the feed carriage on the bottom plate 1.

The feed pitch (the length of movement of the feed carriage 2) is adjusted by a nut 17. In the initial position, the feed carriage 2 is fixed by a spring-loaded rod 19 when it enters the groove 18. When the upper plate 6 moves up, the wedges 4 interact with the upper plane with the lower plane of the wedge supports 3. When In this, the wedge lugs 4 slide along the wedge supports 3, the wedge 5 rotates about an axis, stretching the spring 7.

Upon exiting the engagement of the wedge lugs 4 with the wedge supports 3, the wedge 5 is returned by the spring 7 to its original position. Pushers 27 come out of

interactions with rollers 26 and levers 22 and 23 rotate around axes. The plate 9 under the action of the springs 12 moves along the guide plates 10 downwards and presses the material 8 to the feeding carriage 2. With the further course of the upper plate upwards the clamp 28 releases the material 8. Then the cycle repeats.
