Description

At the census, the H-category .1; m. FIG. 2) the matrix 6 and sn, mnik 7 are fastened. Step knives 8 are fixed in the lorge spit AND are driven from the tail of the JO fixed in pressure plate 11. On the back carriage 2 (see Fig. H) the fixing plate 12 and guide are fixed Yusha 13 rods 14. The rods 14 are secured in the holder 15 and are set in motion from the shank 1 fixed to the pressure plate 17. The rods 14 are spring-loaded with springs 1 in order to prevent breakages in the event of a mismatch. with grooves 19 on the strip, as well as when processing the beginning of the strip (or tape). The drive of the stepping knives, latches and carriages in the drawings is not shown. The holes in the carriage are interconnected with the rods 14.. The device works as follows. . . From the accessory mechanisms through the tailings 1O and 16, the stepping knives 8 and the rods 14 are set in motion in a direction perpendicular to the carriages 1 and 2. The stepping knives 8, interact with the matrix 6 and the supplied material, pierce the holes 19 along the last are simultaneously lowered. rods 14, fixing the feed material relative to the fixing plate 12, using the punched grooves 19. This eliminates the possibility of an arbitrary longitudinal or transverse displacement of the tape relative to the working tool. The mutual position of the cutting current 1, 2, and thus the stepping knives 8 and the rods 14, is adjusted by rotating the nut 5, using gi 3 and 4 with left and right threads. The distance between the split knives 8 and the rods 14 must be equal to the pitch of the stamping, which is integer, and is determined by the construct. After lowering the step knives 8 of the rods 14 1, the carriage 2 moves forward by the feed increment, synchronously with it, the carriage 2 moves into the nut 5 through the rods 3, 4. After the tape is grabbed by the punches of the press, the step knives 8 and the rods 14 reposition the belt, and the carriage is synchronously reset to its original position. The punching of fixing pvs and fixing the tape is carried out to the ovos.: -punts the pins and the back of the group.: 1; i, 1 then, after one step, after which the cycle is repeated; n tape or strip (see fig. 4), when the end of the material exits the i.e. of the action zone of the stepping knives 8, the transfer of material is carried out only with the help of the rear carriage 2 from the rods 14, the front carriage 1 with the pin knives B moves in the hairline. Apply the feed mechanism only from the front carriage according to Aut. St. No. 471931, constructive distance From the stepping knives to the separating punches of the punch is no less than lOO mm, which is equal to the length of the unused piece of material. . Material savings due to full use in length are particularly noticeable when working with strip material. Sheet steel according to TOAST 199ОЗ-74 is produced with a maximum width of lOOd mm and a length of 2OOO mm. When cutting the strip into strips in the longitudinal direction with a strip length of 2OOO mm, the saving is at least 5%, and when cutting the sheet along the width with a strip of 1000 mm, saving at least 1O% of the material. Placing behind the rear carriage N xaism, preventing movement of the ma-. In the directions opposite to the feed direction, it is possible with the help of the supplied device to completely hang all the material through the processing zone and, by the clamps, i.e. behind .

Claims (1)

Claim A device for feeding strip and tape material into the working area of the press according to ed. St. No. 471931, due to the fact that, in order to increase the accuracy of the feed step, it * is equipped with an associated carriage, an additional carriage with holes and gripping bodies made in the form of spring-loaded rods located along both sides of the feed material with the possibility of movement together with the additional carriage in the direction of its movement and relative to the additional 'carriage in the vertical plane AND interacting with the grooves of the supplied material and with holes.
