    The invention relates to the field of mechanical engineering and can be used for joining metal sheets by riveting.
    The aim of the invention is to increase the strength of the joint by eliminating jamming of the working elements during their angular displacement.

В - ° matrix base; on
    Figo 9 is the same, assembled with work items, top view (a base version with a triangular cross section); in fig. 10 a device for sticking together metal sheets having one common die base and two punches; in fig. 11 - a device having several punches on a movable organ of the press and one base mounted on the base of the die with several working elements; in fig. 12 shows a device having several punches and several dies mounted on the press working tool and its frame in alternating order; FIG. 13 shows a device for joining, a general view (an embodiment with a base of a matrix round in cross section); FIG. 14 is a matrix assembled with working elements, square 3 cross section, - in FIG. 15 a device for connection to the ejector with paddles for separating the joined metal sheets from the die and the punch; in fig. 16 — device for connecting, option of executing the movable organ and the frame in the form of pivotally connected levers; in fig. 17 is the same, an embodiment of the movable organ and the bed in the form of DISKS; in FIG. 18 — a node for joining metal sheets with a rivet; a longitudinal section in FIG. 19 is a section A-A in FIG. 18 in FIG. 20 is a connection device having a channel for feeding rivets into the assembly area. The device for sticking the metal sheets with a riveting drive-driven punch 1 with side cutting edges 2 and an end shaping surface 3 and fixedly mounted on the base matrix 4, executed as a base and working elements in the form of flat springs 6, fixed at one end to base matrix and having cutting edges 7 at the other end. The base 5 of the matrix and the working elements are rigidly interconnected by means of, for example, sleeves 8. The shape of the flat springs is usually chosen so that the deformation of the n-about possibility is distributed evenly along their entire length, which is ensured, for example, by making various grooves on their side edges (Fig. 2-4). The distance from the end of the base of the mariente to the cutting edges of the working elements is 0.4-0.9 of the total thickness of the metal sheets to be joined, and the preferred ratio is 0.7. By changing the total thickness of the joined metal sheets in the device, the matrix base can be replaced. Instead of one flat spring in the device, a package of springs can be used (Fig. 5). At the same time, only the internal flat springs 10 54 that adjoin the matrix are rigidly connected to it with the aid of the sleeve 8 and have a cutting edge, while the remaining external flat springs 11 of the package are replaceable. The base of the matrix and the package of springs are placed in the support 12. It is possible to jointly execute the working elements with the support 12 (Fig. 6). Adjusting the shape of the working element in accordance with the most favorable characteristics of the deformation process can be achieved by making flat springs of variable thickness (Fig. 7). The base 5 of the die can be made with bevels 13 in the zone of the recesses 9 for collecting and exchanging chips along which the chips move outside the device. The base matrix 1 (Fig. 9) is made with a cross-section in the form of an isosceles right triangle, and flat springs with; This is angled. In a device of this design, the end shape of the punch also has a cross section in the form of an isosceles right rectangular triangle. A device for connecting by riveting metal sheets can be made with two punches mounted on a movable body of a press; ca, and one common matrix (Fig. 10),; As a result, two joint points are formed simultaneously in one working stroke of the press, the strength of which exceeds the strength of the device with one joint point with a correspondingly increased cross-section. On the movable organ of the press (FIG. 11), several punches are simultaneously mounted, made in the form of protrusions 14 on the plate 15, and one common base 5 and a flat spring 6 fixed by one end on the base of the matrix and divided by slots made at the other end are fixed on the frame 16 on elastic web 17 with cutting edges corresponding to the protrusions 14. In addition, both punches and dies can be mounted on the movable body of the press (FIG. 12). alternately arranged. To avoid warping of the joined metal sheets in the final phase of the joint, the distance 91 between the cutting edges of the working elements of the dies, located on the under-mounted press and stand, in the lower position of the movable member of the press is equal to the total thickness of the joined metal sheets. The base 5 of the matrix (Fig. 13) can be made in the form of a cylinder 18 placed on the base 19 with the possibility of height adjustment. In this case, the flat springs are formed by longitudinal slits 20 on thin-walled bushings. The width and length of the slits can be different. When using a cylinder 21 in the device, the diameter of which is equal to the base diameter of the matrix, the cutting of the sheet metal package takes place in the region of the cutting edges of the flat springs and only in the region of the slits 20 in the case when the punch is made in the form of a cylinder 22, the diameter of which is less than the diameter of the base of the matrix by half the total thickness of the joined metal sheets, the sheet is not cut, but is pressed, ltate place which is soy union of waterproof Base matrix and punch may be formed with a cross section in the form of a polygon such as a square, hexagon, etc. (Fig. 14). An embodiment of the device for sticking metal casts (Fig. 15) provides for a spring-loaded pusher 23 in the design for separating the sheets from the die and the punch. The punch and die together with the iM ejector are mounted on cylindrical bases 24 of equal diameter. The pushers can be located independently of the punch and die. The movable parts of the press of the upper 25 and lower 26 plates are provided with a guide column 27, which ensures their mutual positioning. According to the embodiment of the device, operated manually (Fig. 16), the punch and the die are fixed at the ends of the pivotally connected levers 27 and 28. In the recess of the lever 28 on which the die is mounted. a hydraulic cylinder housing 29 is mounted for relative rotation of the levers. The rod 30 of the hydraulic power cylinder acts on the lever 27, producing a working stroke. The return to the initial position of the lever 27 is carried out by means of a return spring 31. In some cases, it is necessary to close the recess in the metal sheets 32 and 33 when joined by rivet 34, which is affected by the punch. In the device making the connection with the aid of the rivet 34 (FIG. 20), the matrix 4 is placed on the frame 35 and the driving punch 1 is coaxially mounted to it. A groove 36 is made above the matrix, in which the metal sheets 32 and 33 to be joined are placed. The channel 37 for the punch 1 and the rivets 34, which enter the channel 37 from the magazine 38, is also completed. The rivet 34 can be formed by separating from the profile placed in the shop 38 a punch part, which is then installed in the recess formed in the joined sheets. According to an embodiment of the device in FIG. 17 punches and dies are placed respectively on the disks 39 and 40, which are rotatably mounted in the directions indicated by the arrows. During rotation, the discs interact with each other and with metal sheets. The disks 39 and 40 are mounted on the shafts of the bearings and synchronously rotated by the drive. In the areas of the lateral surface between the dies and punches, the discs can be dug covered with friction material, for example, have a soft rubber gasket or are provided with grooves. The device works as follows. The joined metal sheets are mounted on the die, after which the drive movement of the punch is activated. When the punch acts on the joined metal sheets, they are cut by the edges of the punch and flat springs that are opposite to the cutting edges and deform the recess.
    71
    in the lintel formed by the slots; whereupon the flat springs are deflected in opposite directions relative to the base of the die, and with further movement of the punch, the second stage of the jumper deformation takes place, at which the sheets are permanently joined. In the case of rivet 34, which is affected by a pant 9258
    sleep, the formation of slits and the deformation of the metal sheet is carried out by the body of the rivet, which remains in the recess obtained in the sheets.
    The use of the proposed construction of a device for bonding riveted metal sheets to a liver; an increase in the strength of a joint.
