In sheet material, a series of equal lengths of cuts 1 is obtained, then the material is moved a step equal to twice the distance between rows of cuts with a staggered arrangement, and they form a second row of cuts 2 parallel to the first one. The cuts are made at the same location. Then simultaneously form two

a number of cuts 3 and 4. A series of cuts 4 are made at a distance from a number of cuts 2 equal to the distance between cuts 1 and 2, and cuts 4 are placed identically with cuts 1 and 2, and a number of cuts 3 have

at a distance from the row of notches 1, equal to half between a pair of previously obtained rows, and the notches 3 themselves are located in a row with an offset that provides the chess arrangement of the notches 3 relative to

cuts 1, 2 and 4. Formation of rows of cuts similar to rows of cuts 3 and 4 are repeated as many times as necessary, and one of the rows of cuts, cuts 5, obtained at the third transition, have

between the rows of cuts 1 and 2, and after five rows of cuts are formed, the edges of the cuts, which lie on both sides of the cuts of three adjacent rows, are shifted in the direction perpendicular to the plane of the non-deformed sheet, adjacent to each of the cuts, the section is bent at an angle a to the plane of the material, and the incisions are stretched When each next five is formed

row of cuts, the upper edges 6 of the previous row hold against displacement. As a result of making cuts with chess

positioning and bending receive scaly cells.

The stamp contains a movable upper 7 fixed lower 8 plates, connecting them with guides 9, a matrix holder 10 with dies 11 fixed on the plate 8, a punch holder 12 with punches 13 fixed on the plate 7. In addition, the stamp contains a material transfer unit made in the form of a feed carriage 14, a bottom carriage 15, a pressure carriage 16 and a conversion mechanism connecting the carriages 14, 15 and 16 to the plate 7 and informing them of movement.

The cutting edges on the teeth x of each punch 13 and each die 11 are located on the same straight line, the teeth of one punch are arranged in a checkerboard pattern relative to the teeth of the other, and also in a checkerboard pattern, the tooth of the adjacent dies. Each tooth of punches and dies is a cutting plate 17, which is removably mounted. The punches 13 are placed at a distance from one another equal to 2.5 material feeding steps. An insert 18 is installed behind each punch 13 to hold the edge of the notched portion. The insert 18 is made with teeth that are similar in shape to the tooth of the punches 13, the arrangement of the teeth is similar to the arrangement of the teeth of the corresponding punch.

The feed carriage 14 includes a base 19, two sliders 20, gripping bodies in the form of rollers 21 and rollers 22 and 23. On the carriage 14, a tray 24 is installed, hingedly connected to the sliders 20 of the axis 25. Tray 24 has guide rails 26 and 27. 28 and clamping rollers 29 and material braking means 30. The fingers 31 are fastened in the half-heel 20.

The bottom carriage 15 is connected by ribs 32, which pass through the holes in the core holder 10, with the base 19 of the feed carriage 14.

On the bottom carriage 15 is fixed a gripping body, made in the form of a lever 33 mounted on an axis 34 so as to rotate, a gripper 35 equipped with a spring 36 and placed at one end of the lever 33 placed at the other end of the lever 33 on its different sides of the elastic element 37 and an anvil 38 fixed to the plate 8. In addition, the bottom carriage 15 has a table 39 supporting the resulting mesh.

On the gland carriage 16, the gland element 40 is mounted and the axles are fixed

41. In order to guide the axles 41 when moving the gland carriage 16, there are two posts 42 with guides 43 mounted on the bottom plate 8.

The transforming mechanism contains

a pair of parallel-mounted copiers 44 interacting with the fingers 31 fixed in the sliders 20 of the feed carriage 14, and two pairs of parallel-mounted parallel copiers 45 interacting with the axles 41 fixed to the gland carriage 16. The copiers 44 are formed by slats 46 fixed on the disks 47 that are pivotally mounted,

5 serves for adjusting the feed step of the material to be processed in the slats 46 secured to the top plate 7 of the stamp. Copiers 45 are made in disks 47 mounted in walls fixed to

0 top plate 7 stamp. The disks 47 are installed with the possibility of rotation and are equipped with brackets 48, connected by springs 49 with axes 41 of the pressing carriage 16. The forces of the springs are directed along the copiers

5 45 down, and they press the axles 41 against the guides 43.

The stamp works as follows. When the die is in the closed position, the blank sheet material, in particular,

0, 1-2 mm thick, 400 mm wide, is fed between rollers 22 and 23 by rollers 21 through tray 24 up to the stop into the first punch 13 during the feeding. When the upper plate 7 moves upward, the guide bars 46 act on

5 fingers 31, rollers 21 capture the processed material and move it one step. The braking means 30 keeps the material on the tray 24 from a possible displacement. Material based on

0 to tray 24, over the roller 28 and pressed against it by the roller 29.

Upon further raising of the top plate 7, the finger. 1 31 out of contact with the guide bars 46.

5When the top plate 7 moves

The first material punch 13 presses the material to be machined to the matrix 11. At the same time, the fingers 31 are again in contact with the guide bars 46, as a result of which the feed carriage 14 begins to return to its original position.

Then the punch 13 and the matrix 11 form the first row of notches 1, simultaneously

5 bend and stretch their edges.

Further, with each upward movement of the plate 7, the processed material is supplied to the step.

With the formation of a second row of cuts 2 edges 6 previous about yes cuts

1, located at the top, is kept from displacement by the insert 18.

The formation of cuts 3 with a checkerboard with respect to cuts 1 and 2 is carried out by the second punch 13 as the material is moved. The edges of the 6 cuts are held by an insert 18 adjacent to this punch 13.

In the process of making cuts, tray 24 oscillates in the vertical direction and provides the same movement to the material being processed.

After the formation of several rows of notches, the gland element 40 enters into operation.

Subsequently, when the upper plate 7 is moved upwards with the copier 45, in contact with the axles 41, the carriage 16 is moved along the guides 43 to the right (according to the drawing). After the axles 41 touch the bottom surface of the copiers 45, the carriage 16 begins to move upwards, while the supply of the material being processed continues.

At the beginning of the movement of the upper plate 7 downward, the axis 41 of the carriage 16 lies on the direction

43, the gland element 40 comes into contact with the upper edges of the notches 6, the carriage 16 moves to the left (according to the drawing).

After getting the part of the grid to work

the gripping body of the undercarriage 15 enters. In the initial position of the feed carriage 14, the grab 35 tons of the undercarriage 15 is sunk and moves a distance,

equal to the pitch. At the end of this movement, the lower end of the lever 33 meets the stop 38, rotates and compresses the elastic element 37. At this moment the spring-loaded gripper 35 is deflected to the side

movement of the material being processed and pressed against the lower edge of the notch.

After the release of the front end of the material being processed from contact with the gripping bodies of the feeding carriage 14

the movement of the material is carried out only by the carrying carriage 15.

Using the proposed method and the stamp will allow you to expand the range of the resulting nets due to the formation

scaly cells and improved positioning accuracy of the latter.
