    The invention relates to a device for forming heads on rods, in particular, going through nails.
    A device for shaping a head on a rod is known, comprising an annular tool with matrices arranged around its circumference, with holes and cheeks for placing and fixing the rods and a deforming roller mounted rotatably around their axes Cl.
    However, the known structure is complex and inefficient.
    The purpose of the invention is to simplify the design of I. productivity.
    The goal is achieved by the fact that in a device for forming a head on a rod containing an annular tool with matrices with holes and cheeks disposed around its circumference for disengaging and attaching the rods and a deforming roller mounted rotatably around their axes, the deforming roller is placed inside the annular tool so that their axes are parallel, and the axes of the matrices are perpendicular
    axis of the ring tool.
    The axis of each matrix is located at an acute angle to the radius of the annular tool.
    Ring tool contains
    at least two rings with a corresponding number of semi-matrices, wherein the planes of rotation of the rings form one acute angle relative to the other.
    Each ring and a roller in contact with it have raceways made respectively on the inner surface of the ring and the outer surface of the roller, while the diameter of the roller raceway is less than the diameter of the roller, interaction with the shaft, and between the twist. A gap is provided for the roller and the matrix surfaces. The rolling tool tracks of the ring tool are designed as a gear. Each matrix cavity includes a canal shaped half-wide, equally increasing at the end, turning 4 to the center of the ring tool G with the aim of providing opportunities for manufacturing rods with a L-shaped head, one neck of the matrix is larger than the other, and the roller size & so that its flat lateral surface forges the high cheek. V One cheek of the matrices is placed above the other and the roller has an annular high on the side of the lower cheek of the matrices aa deforming roller shaft according to Kpafliiee, on one side it has a gear wheel, and the ring is equipped with other eubes placed on its inner surface with the possibility of interaction with a cogwheel wheel of a roller :, moreover, the diameter of the pitch circumference of the gear wheel is less than the diameter p of the surface of the deforming roller, facing the dies. The device has one rim gear to interact with the internal teeth in one of the rings, and between the roller and the ring there is a protective plate located close to the inner surface of the ring. The working surface is made rough. The roller f of the middle part of the working surface has an annular flange. FIG. 1 shows the interaction of the deforming roller with the annular tool; in fig. 2 is the same; in fig. 3 device, general view; Fig.4 section aa in Fig.3; in fig. 5 and b versions of the ring tool; in fig. 7 shows an embodiment of the device of FIG. 3; in fig. 8 - clamping means; in fig. 9 shows an embodiment of the device of FIG. 3; in fig. 10-12 matrix placement options. The roller 1 rotates in the direction of the arrow A and interacts with the blanks attached to the ring tool 2 for nails 3 and 4 (Fig. 1). The ring tool 2 moves progressively in the direction of the arrow B. The circumferential speed of the roller 1 is somewhat better than the speed of movement of the ring tool 2. The cavity 5 defines the shape of the rod head. The entry angle and (Lig.1) is equal to the angle between the tangent to the deforming roller 1 at the point where it initially collides with the rod 3 and the tangent to the ring tool 2 at the point where the stem {pgev 3 is fixed in the ring tool 2, tangent to the ring tool Z is parallel to him. In order to manufacture rods 3 and 4 with a reduced head (ftsg..2} the angle of entry V must be somewhat larger. With a rod 3 with a rotate 1, the rod 3 will bend back and viii to the cavity 5. The angle V becomes sharp, the friction between a deformed roller 1 and rod 3 leads to initial rolling, which provides rods without burrs and with a certain tolerance. The ring tool 2 (Fig. 2) has internal b, which pass with a certain axial clearance between it and the sides of the deflating roller 1 and is in. with the gear wheel 7, the rotation of the motor from the motor 8. The circumferential speed of the deforming roller 1, extract the inner circumferential speed of the ring tool 2 and their C and L axes are parallel (figure 3) .The operations of editing, cutting, tapering, inserting the rods into the ring tool 2 performed At the position 9. The finished rods with heads are removed at the position 10. The rods 3 and 4 are inserted radially between the inclined walls 11 in the cheeks 12 for placing and fastening the rods. The annular tool 2 (Fig. 4) consists of two rings 13 and 14 inclined relative to each other, fixed respectively on the inner rings 15 and 16 of the sub-riders. The outer rings 17 and 18 of the bearings are fixed on the support plates 19 and 20. The plate 19 is fixedly mounted on the base 21, and the plate 20 is hinged. The plates 19 and 20 are moved relative to each other by means of the bolt 22. The deforming roller 1 is fixed on the shaft 23, which is installed with the possibility of rotation in the plates 19 and 20 on spherical bearings 24 and 25. Each ring 13 and 14 has an annular track 26, and the deforming pipe 1 - raceways 27 and 28, made on its outer surface. The diameter of the roller raceway is smaller than the diameter of the surface of the roller that interacts with the rod; Surface 29 of roller 1 interacts with the rods. The annular tool 2 has a matrix 30 arranged around its circumference with holes 31 and cheeks 12 (Fig. 5). Each cavity of the matrix 30 includes a channel-like cavity, which passes into a uniformly enlarging recess 32 at the end facing the center of the ring tool 2. A gap ft is provided between the surfaces of the roller 1 and the surfaces of the matrices 30. When the track 27 or 28 of the roller 1 moves along the track 26, it is possible to obtain the required velocity difference, determined by the gap c (Fig. 5). As shown in FIG. 6, the groove track of the annular tool 2 is made in the form of a toothed wheel 33. FIG. 7 shows an embodiment of the device in which the rings 34, 35 and 36 are fixed on the inner rings of the sub-tips (not shown). The roller 37 has raceways 38 and 39, interacting with rods 40 and 41, secured in detachable tools 42, 43 and 44, 45. Rolling tracks 38 and 39 are provided with an annular collar 46 and 47 in the same plane with cores 40 and 41. Burrs 46 and 47 pass with a gap in the notches 48 and 49 in the tools and make slots in the heads of the rods 40 and 41. ROLLER 37 also has rolling roads 50, 51 and 52 in contact with the corresponding rolling tracks on the rings 34, 35 and 36. The ring 35 can be rotated not only by the roller, but also by means of parts connected with it rzhni in the work area. The dies 53 and 54 pass through the corresponding holes in the rings 34 and 36, protrude on the outer flat sides of these rings and come into contact with clamping means 55 which exert great pressure on the dies 53 and 54 in the working area, with the result that the rods 40 to 41 will be held against axial movement when interacting with roller 37. Clamping means 55. 8) contain sprockets 56 and 57, which set in motion a chain consisting of folding plates 58 and rollers 59. Between the sprockets 56 and 57 there is a guide block 60, which is pressed in the direction of the chain. Guide block 60 has a chain guide 61 for determining the size of the working area. FIG. 9 shows a different embodiment of the device. The outer rings 62 and 63 of the bearings are attached to the side plates 64 and 65. The inner rings 66 and 67 of the bearings extend relative to the side plates 64 and 65 with a clearance. The inner ring 66 has teeth that meshes with the teeth 68 connected to the electric drive (not shown). The inner rings 66 and 67 have matrices 69 and 70. The shaft 7.1 is fixedly connected to the deforming roller 72, rotated by the gear wheel 73, which is fixedly connected to the shaft 71 and meshes with the teeth 74. The pitch diameter of the gear wheel 73 is smaller than the diameter of the roller 72 facing the dies, whereby the circumferential speed of the roller 72 exceeds the speed of the end of the rod 75 interacting with the roller 72.. Between roller 72 and a ring 66 accommodates a protective plate 76 located close to the inner surface of the ring and to the side plate 64 by means of supporting legs 77. A rod with a round head 80 in contact with the roller 72 is placed between the cheeks 78 and 79 of the matrix (Fig. 10). with the L-shaped head (Fig. 11), one cheek 81 of the matrix is placed above the other cheek 82. The roller 72 is placed so that its flat side surface 83 contacts the high cheek 81. In FIG. 12 shows that one I matrix cheek 82 is located above the other cheek 81. The roller 72 has a ring-. the protrusion 84 from the lower face of the matrix. Between the surface of the roller 72 and the protrusion 84 there is an annular radial surface 85 that prevents the formation of burrs. The proposed device has a simple structure. Due to the internal rolling, optimum working conditions can be obtained which will improve productivity.
