(54) DEVICE FOR SUBMITTING MATERIAL TO A TREATMENT AREA

(57) The invention relates to the cold working of metals by pressure and can be used to feed material into the treatment area. The goal is to expand technological capabilities by providing a supply like

strip and tape materials. In the material, in the processing zone, holes are cut down to form bridges between them. Into the holes The feeding carriage enters. The carriage is driven from the movable plate through the lever. The lever is hinged at one end on the movable plate. The feed carriage is hinged at the free end of the lever. A guide is mounted on the fixed plate, interacting with the rollers mounted on the feed carriage. On the top plate (bracket) fixed stop, limiting the rotation of the lever in a vertical plane parallel to the axis of the material feed. 2 Il.

;about

The invention relates to cold metal forming and can be used to feed the material into the processing zone. The purpose of the invention is to expand the technological capabilities by filing strip and strip material.

1 shows a device for feeding a strip and tape material to the treatment area, the initial position; figure 2 - the same, the working position.

The device contains an upper sub-plate 1, on which the punch 2 and the bracket 3 are fixed. In the latter, using the axis 4, the lever 5 is mounted, spring-loaded 6. The bracket 3 is fixed or made at the same time with it an emphasis 7, limiting turning the lever 5 around the axis 4. At the end of the lever 5, the axis 8 of the feed carriage 9 is pivotally mounted. The feed carriage contains an axis 8 with supporting rollers 10, an axis 11 with supporting rollers 12, a limiting stop made in the form of a bracket 13. 14 are made in one piece with it or secured - a guide 15 for moving the feed carriage 9 on it and the matrix 16 is mounted. Parts 17 are cut out of material 18, strip or tape to form holes 19 in material 18 and jumpers 20 between holes 19.

The device works as follows.

When plate 1 moves downward, the feeding carriage 9 enters hole 19, rollers 10 and 12, interacting with guide 15. With further movement of plate 1 down, lever 5 rotates around axis 4 and moves the feeding carriage to the left (Fig. 2). The carriage with the help of rollers 10 and 12 moves along the guide 15 and acts on the jumper 20 between the punch cut by the punch 2 and the matrix 16 of the holes 19 and moves the material 18 to the feeding step (Fig. 2). In the leftmost position (Fig. 2), the distance in height q from axis 8 to axis 4 should be greater than distance b from the upper plane of material 18 to the lower end of punch 2. When Plate 1 moves up, lever 5 remains in a fixed position relative to the bracket 3 fixation mechanism (not shown).

The feed carriage 9 escapes from the rod 18, the lever 5 under the action of the spring 6 rotates around the axis 4 and is fixed relative to the bracket 3 by the support 7. The clamp 13 restricts the rotation of the feed carriage 9 relative to the lever 5.

Claims (1)

Invention Formula A device for feeding material into the treatment area, containing a movable and fixed plate, a guide mounted on the fixed plate, a lever pivotally fixed at one end on the movable plate with the possibility of rotation in a vertical plane parallel to the axis of the material feed, feeding carriage pivotally mounted on the other end of the lever can be rotated in the vertical direction, and the support frames mounted on the feed carriage with the ability to interact with the guide, characterized in that enhancing technological capabilities by feeding a strip and band material, it is provided with a stop to limit the rotation of the feed carriage relative to the lever, fixed to the feed carriage with the ability to interact with the lever, and the spring, with the levers spring-loaded in the direction towards the bottom plate. 10 9 9 12; / W g .;
