Description

one

The invention relates to the processing of metals by pressure, in particular to the equipment for corrugating the tape.

From the main auth. St. No. 502680 is known stamp for the manufacture of 5 corrugated tape. The working parts of the punch and die are made with several successive zones of shaping, approaching and calibrating the corrugations. The first two zones have a variable in the longitudinal direction the width of the holes and protrusions located at a given angle relative to the longitudinal axis of the punch and die. In the stamp, on both sides, side plates are installed, which interact with the side walls of the punch and die. The side slats have the ability to rotate around an axis. The protrusions and depressions are calibrated, its zones have a constant width and height. The tape, moving along the 20 nouns and the matrix, is narrowed to form corrugations that take on the final shape in the calibration zone.

On a known stamp, you can get a tape of a certain width and the stamp cannot be readjusted to the other 25 sizes of tapes.

The aim of the invention is to expand the range of products obtained.

To achieve this goal, a 30

the cutting zone is placed behind the calibration zone, made in the form of a holder mounted on a movable nlite with rigidly cut punches fixed to it and with the possibility of being interchanged by split punches, as well as a knife block mounted on a fixed plate.

FIG. 1 and the proposed stamp B is shown in longitudinal section; in fig. 2 - the same plan view; in fig. 3 - misfire zone in cross section; in fig. 4 - punch to the matrix of the calibration zone.

The stamp contains iodvig plate 1, on which the ramming enansons 2, the holder 3 with two edged punches 4 and removable split punches 5 (one is shown), the bottom plate 6 on which the matrix 7 and the block of knives 8 are fixed. matrices 7 are made in the form of combs, and the protrusions of the punch 2 are located respectively to the troughs of the matrix 7. On both sides of the matrix 7, there are lateral stripes 9, which are designed to rotate about the axes 10 with the help of the cams I, which are in contact with the rollers 12. Poinsot 2 and the die 7 form three successively arranged zones: molded 13, proximity 14 and calibration 5, and punches 4, 5 and the knife block 8, located behind the calibration zone, form a cutting zone 16. Moving plate 1 is guided by columns 17 when moving. 13 and 14 have a variable in the longitudinal direction the width of the hollows and the protrusions arranged at an angle relative to the longitudinal base of the punch 2 and the die 7. The cut punches 4 are fixed in the holder 3 permanently, and the split punches 5 are placed in one of the slots of the holder 3 and secured to him vi ntami 18. The knife block 8 has cutting edges along the edges for a maximum width of tape 19 and cutting edges of the required width.

The stamp works as follows.

Tape 19 is fed to the forming zone 13. After each stroke of the punch, the tape is moved to the schag. When moving the movable plate 1 downward, the tape in the forming zones 13 and approaching 14 is corrugated and reduced in the transverse direction, guided by its corrugations relative to the projections and depressions of the punch 2 and the matrix 7, and the cams I act on the rollers 12 of the side slats 9 and move them that they are ilotically pressed against the side walls of the punch 2 and the matrix 7. As the belt advances along the matrix 7, the height of the corrugations increase /:, the distance between the corrugations and the width of the corrugated tape increases. The final step is to calibrate the tape in zone 15, cut it and cut it in zone 16. The punches 4 cut the corrugated tape to the maximum width and

cutting punches 5 cut into pieces. If it is necessary to obtain a corrugated tape of a different size in width, the split jaws 5 are not reinstalled into the corresponding groove of the holder 3

and fasten with screw 18.

The use of this stamp allows you to get a corrugated tape of various spiria in one stamp, thereby reducing the consumption of metal and reducing the complexity of obtaining corrugated tapes, increasing labor productivity.
