    Apparatus for necking-in at least one end portion of a substantially cylindrical can body includes expandable and contractable gripping means for positively gripping a peripheral surface of the can body over a major portion of the circumference and length thereof to positively hold the can body in a substantially cylindrical shape. Female and male forming rolls act against a terminal end portion of the can body to deform the terminal end portion inwardly. The female forming roll is positioned within an open end portion of the can body and is moved outwardly into engagement with the terminal end portion of the can body to form an outwardly extending flange thereon for stiffening the end portion of the can body against wrinkling. A male forming roll positioned outside of the can body is moved toward the female forming roll to neck-in the terminal end portion of the can body.

    (5) DEVICE FOR FORMING THE EDGE OF CYLINDRICAL
    one
    The invention relates to the processing of metals by pressure and can be used in the processing of the edges of cylindrical articles, for example | ep, tin can bodies.
    A device is known for forming the edge of a cylindrical product, which comprises a driven mandrel mounted on the base, two forming rollers, one of which is made with a forming protrusion and the other with a forming groove, as well as attachment points for the rollers 1; v
    A disadvantage of the known device is the discrepancy between the quality of the edge processing and the requirements imposed on it.
    The purpose of the invention is to improve the quality of molding.
    The set goal is indicated by the fact that in the device for forming the edge of a cylindrical article containing the base-mounted oppaBt y with a drive and two forms- 25. PRODUCTS
    one of which is made with a forming protrusion, and the other with a forming groove, as well as the roller attachment points, the roller with the groove is made with two forming sections located on either side of the groove, each roller attachment node is mounted on the base with the possibility of movement and the form of a rotary stand with an eccentric shaft, located in the stand parallel to the axis of the mandrel, and each forming roller mounted on the end of the corresponding eccentric shaft.
    The forming roller with a groove is provided with a clamp for the position of the can body, made in the form of a thrust hub.
    The device is equipped with a hinge of the rotary stand with a forming roller with a protrusion in the direction. perpendicular to the axis of the mandrel,
    FIG. 1 shows the device, a general view; in fig. 2 - section A-A in FIG. one; in FIG. 3, the semen BB in FIG. one; in FIG. 4, view B on. one; in fig. 5 is a cross-section of the FIG. in fig. 6 is a section DD-D in FIG. four; in fig. 7-11 depict forming steps; in fig. 1217 - the steps of forming another profile of the hull edge. The device comprises a mandrel 2 mounted on the base 1, consisting of clamps for fixing the can body 3. The mandrel 2 is mounted in the bearing C, a pulley 5 is mounted on the mandrel. The belt 6 connects the pulley 5 to the output shaft 7 of the motor 8. The mandrel 2 is made with an external cylindrical surface and a central tapered bore 9. In the mandrel 2, slots 10 are made between which clamping elements 11 are located. The slits 10 extend from the end of the mandrel in the direction of the pulley 5 along most of the mandrel length. The end portion of the mandrel has a threaded hole 12. The conical expansion element 13 is disposed in the opening 9 and is intended to push the clamping elements 11 in the radial direction. The expanding element 13 is made with an axial hole And and a conical outer surface which has the same taper as the surface of the hole 9. The bolt 15 with the threaded END 16 and the head 17 passes through the holes 12 and pushes the expandable element 13, which, moving in the radial directionally, ensures a secure fixing of the jar on the mandrel. The device also contains a roller attachment unit 18, consisting of a support 19 with holes 20 and 21, in which axles 2 and 25 with threads 28 and 27 are pushed through bearings 22 and 23 and screwed into threaded holes 28 and 29 of rotary glasses. 30 and 31. Racks 30 and 31 rotate on axes x 2i and 25 around axes 32 and 33 In the rack there is a hole in which an eccentric shaft 35 is installed, and a forming roller Zb with a groove is mounted through the bearing 37. Chute 38 forms a concave curved surface of the roller, having in addition the forming section 39 of one di The meter and the forming section 40 are large dia 4 4 meters. The axial bushing A1 may be located on the run-in roller with a groove, adjacent to the kO portion. A support element 2 is fixed to the support 19 with a threaded hole 3 through which an adjusting bolt kk runs, abutting against the pivot post 30 and providing for an adjustable rotation of the post 30 around the axis 32. The post K 30 also has an opening kS, into which the pin 46 enters. -47 Large Aiameter than hole 45. Included is an adjusting screw 48, which presses pin 46, providing adjustment of the position of the stand 31 relative to the stand 30. There is a hole 49 in the stand 31, through which passes through the eccentric slide bearing 50 the first shaft 51. The shaft 51 is mounted a forming roller 52 with the protrusion. The roller 52 is seated on the bearing 53. The wolf has a -concentric convex surface forming the forming protrusion 54, as well as an edge portion 55 0 (| Orc element 5b is fixed on the support 19 and is made with a rejection 58. One end of the spiral spring 59 enters the hole 60 and another into the recess 61 in the rack 31, and presses the rack 31, displacing the roller 52 with a protrusion in the direction of the roller 36 with the groove. The preload force is adjusted by a screw 58. The roller control device includes levers 62 and 63 fixed on the shafts 35 and 51 Between. The axis of the shaft 35 and the axis around which The roller 36 with a chute rotates, there is an eccentricity in which the shaft 35 rotates as the lever 63 rotates in the direction opposite to the clock hand, causing the roller 36 to move to the left. Rotation of the lever 35 in the clockwise direction causes the face horizon to shift 36 to the right (Fig. 4). Turning the lever 63 clockwise causes the shaft 51 to rotate clockwise, and when the lever 63 and the shaft 51 rotate counterclockwise, the roller 52 with the nepie protrusion moves to the left. The support 19 can be mounted on the base 1 movably. During operation of the device, the can body 3 is mounted on the mandrel 2. The support 19 moves in the direction of the mandrel 2 to a position where the flange portion of the can is between the rollers Zb and 52. The roller 36 with the chute is located inside the can body the direction of the mandrel 2 to the support sleeve “1, as a result of this, the forming roller Zb with a groove is installed inside the edge section of the can body 3, and its second edge part kQ is adjacent to the edge of the can body 3 and section 39 is located inside three body banks.
    After this, the motor 8 is turned on, which causes the canister 2 to rotate with the can body. When the can body is rotated, the lever B2 moves counterclockwise in order to move the forming roller B 3 with the groove in the direction of the longitudinal axis of the mandrel and bring it into contact with the inner surface banks of the regional section O. The flanging of the outer flange reinforces the regional
    plot of the can body, preventing wrinkling. To form the outer flange on the can, the forming roller 52 moves in the direction of the longitudinal axis of the can body by turning the lever 63 clockwise. The protrusion of the roller interacts with the surface of the can body on its edge portion and enters the groove 38 on the roller. During the crimping operation, the edge of the can body contacts to the edge area 55 at polik 52, in order to adjust the length of the outer flange on the can body. Section 55 on the roller 52 has a greater width than the thickness of the edge of the tin can, with the result that section 40 of the forming roller BZ can engage with the section 55 of pressing the flange edge outwardly relative to the can body. After the crimping operation has been completed, the levers 62 and 63 are retracted to their original position, the rollers 36 and 52 are moved apart. The shape and dimensions of the outer surfaces of the groove 38 and the protrusion 5 of the rollers B and 52 are chosen such that the rollers do not crimp the housing from the junction box in the transition section the process of formation of a concave side section, which is important to prevent folding.
    These dimensions and the shape of the rollers correspond to the formation of the protrusion B5, as a result of which the stresses are removed at the edge portion of the can body.
