    The invention relates to the processing of metals by pressure, in particular to devices for joining sheets by riveted seam. The purpose of the invention is to increase profitability. The device comprises a punch, a die and an anvil. The punch is made with a displacement drive relative to the die and the anvil. The device has a puller to release the joined sheets from the punch. The sheets to be bonded are pushed through in the first stage in the interaction of the punch and die, then pushed to the second stage, where the punch interacts with the anvil. In the process of their interaction, a rivet head is formed. 16 hp f-ly, 13 ill.

    The invention relates to the processing of metals by pressure, in particular to devices for joining sheets by the method of extrusion,
    The purpose of the invention is to increase the profitability of the device.

    side view; in fig. 13 is a front view of the machine in FIG.
    The proposed device has a punch 1, a matrix 2 and an anvil 3.
    In figure 1, the punches 1 are evenly distributed around the circumference of the plunger rotor 4, are made the same, their radially directed working surfaces 5 are quadrilateral. On the front side they can also be rounded.
    Sheets 6 and 7 to be joined are initially resting on the upper side of the matrix holder 8 and the anvil. Matrix 2 is a block with a U-shaped profile (Fig. 3). The groove facing the punch rotor is of such width on the corresponding side that the edges bounding it with the counter edges of the punches cut the sheets. The groove expands somewhat inward (FIG. 3). Anvil has

    here, the shape of the roller 9 rotatably arranged through the trunnions 10 in the holder 8. As can be seen in Fig. 2, the roller lies behind (partially below) the die 2. The roller 9 is larger and wider than the die slot, and the upper side of the die lies at an adjustable distance and closer to the piercing rotor than the outer circumference of the roller 9.
    By shaping the circumference of the roller 9, the shape of the riveting head can be influenced. In particular, the profile of the circle can be made so that the part of the extruded material, which is located on the side of the matrix, has lateral support, which prevents its expansion without preventing the expansion of the sheet (s) located on the side of the anvil. This ensures high load-capable riveting heads.
    Instead of the roller 9, the lever 12 returned by the spring 11 can be used as the anvil (FIG. 4).
    To prevent wear due to relative movement between the die and the sheet 7, the die can also be performed as a spring-return tipping lever (Fig. 5).
    It is also possible to allow friction of the sheet 7 in the anvil zone, i.e. perform an anvil 3 with a stationary working surface, preferably polished (Fig. b). In principle, each type of matrix presented can be combined with each type of anvil shown.
    Alternatives are also provided for making the punch and the punch rotor. While in FIG. 1, individual punches are mounted on a punched rotor with the possibility of replacement, in FIG. 7, the puncheon is made in one piece with the star rotor in the shape of a star 13, which is reinforced on both sides by support rings 14. In FIGS. 8 and 9 It is shown how on the punching wheel 4 (as in Fig. 1) there is a scraper ring 15 supported on a spring 16 by which the joined sheets are pressed through by the punch. Instead of a full punch rotor, a reciprocating sector with one punch can be provided .
    In Fig. 10, a punch block 17 is provided, consisting of a middle block 18, two control blocks 19 and parallel punches 1 fixed on them (only one is visible). The middle block is connected via a planar spring 20 (not indicated) with reciprocating movable drive (arrow A), hydraulically driven, so that the punch block can move relative to the stationary control housing 21. The walls 22 of the housing 21 carry control wings 23, on which the control blocks run, due to slopes 24 are raised (arrow B), besides The flat springs are deflected until they return.
    0 to their original position behind the control wings. If the actuator now rotates, then the punch block, due to the interacting wedge surfaces 25 and 26, presses down, namely into the sheet that is supported on the matrix, and on the way back, pushing and the formation of a rivet head occur. Behind the steering wheels, the spring 27 lifts the punch from the connection point.
    0 FIG. Figure 11 shows schematically the structure of the machine by which the longitudinal seams of the pipes are closed. From the receiving base assembly 28, the first console 29 extends, carrying a ringing rotor 4, and the second console 30, parallel to the first, carries an anvil matrix node. The drive torque is transmitted, for example, by means of a rotating circuit 31. A second console is mounted on
    0, the bearing 32 can be rotated so that the finished part 33 can be removed. Also shown is an actuator 34 for turning.
    A similar machine with two consoles is shown in Fig. 12, but here the feed direction is provided across to the consoles. With such a machine, several pipes can be laid in a row, as well as long, wide, profile parts can be made.
    Similarly to FIG. 10, with the rotating punch rotor, several punch rotors can be mounted next to each other, each of which is designed
    5 one node matrix-anvil. The punches can work in the same phase and in phases that are biased one to another. An installation for connecting a flat sheet with a corrugated sheet may, for example, have as many connection nodes, as many connection lines as necessary, and the connection process can be performed in one working process.
    The device works as follows.
    If sheets 6 and 7 (in the drawing) are fed to the left on the holder 8 and along the upper side of the matrix 2, then they fall into a point at which the upper side of the sheet 6 intersects the circle shown by the dashed line
    working surface 5 of the punch 1. The punching rotor A is rotated counterclockwise. The closest punch, starting at the intersection point, incised, in cooperation with the stationary matrix 2, two parallel slots through the sheets which are gripped by the punch. The material between the two slots is forced in the direction of the anvil and the size a is set so that between the working surface of the corresponding punch 1 and the circumference of the roller 9 there is less space than the sum of the thicknesses of both sheets. The roller 9 is then rotated at a corresponding small angle. The sheets are transported by the punch 1 until it leaves the thus obtained first connection point. This is preferably the case when the next dowel begins to incise the next junction point.
    Both the matrix and the anvil are preferably made of hard alloy. Both are quite durable and long for long life.
    The punch and die do not necessarily have to be cut through the sheets. If the transverse dimension of the punch is shorter than the distance between the cutting edges of the die, then the sheet lying on the side of the punch is not cut first, so that the corresponding connection points are sealed. If, however, the matrix is supplied not with cutting, but with rounded edges, then none of the sheets is cut. Sheets are joined without cuts.
    The device can be made in the form of a mobile apparatus that is moved manually or by means of guides along a seam line of a rigidly clamped or large-sized part.
