The invention relates to the processing of metals by pressure, in particular to the equipment for manufacture by rolling the forming tool lightweight pressure vessels, mostly thin-walled gas cylinders high pressure of 100 kgf/cm2and above (used in breathing apparatus rescue and scuba divers), is intended for hot sealing necks and bottoms of the cylinders of the tubular and forged blanks and may find wide application in the manufacture of the latter.

Design training) with sakatani bottom with one hand and sakatani neck with the other hand, moreover, the sealing is made with the preliminary heating of the ends of the workpiece.

Known installation for the manufacture of cylinders containing mounted on the frame and arranged in the processing sequence is installed with the possibility of reciprocation perpendicular to the axis of the workpiece, a mechanism for feeding blanks, mechanism for heating the workpiece, mechanism for closing the bottom and neckline, and a conveyor for removing the finished product. Additionally it is equipped with table driven reciprocating movement perpendicular to the axis of the handle and mounted on the table reciprocating axial movement of the rotary head, made in the form holder and fixed on its mandrel for closing the neck of the container and the mandrel supporting the workpiece on its inner surface, while the conveyor is placed on said table.

The technical result of the invention is to reduce the complexity of manufacturing cylinders by increasing productivity and quality of their production.

In Fig. 1 depicts the installation, top view; Fig. 2 the mechanism supporting roller; Fig. 3 mechanisms in the heating zone (Fig. 1) and further to the tray 3 resetter 4. For heating the end of the workpiece 2 is used circular inductor 5 mechanism 6 move (e.g., hydraulic cylinder) of the inductor 5. In addition, the installation includes satellitel 7 (for example, pneumatic cylinder) with rotating head 8, the mechanism 9 of the clip and push the front of the spindle head 10, the mechanism supporting roller 11, the mechanism of the forming roller 12 and the tray 13 discharge for placing the finished cylinders 14. All of the above mechanisms are mounted on the frame 15, and the mechanism forming roller 12 on the rotary plate 16.

The mechanism supporting roller 11 (Fig. 2) contains a hydraulic cylinder 17, the piston rod 18 through which the rack 19 is rigidly fixed to the movable plate 20, and mounted on it bearing unit 21 with the roller 22 with the possibility of linear movement of the movable plate 20 in the guide rails 23 at an angle to the axis of the handle.

The mechanism of the forming roller 12 (Fig. 3) mounted on the rotary plate 16 and contains a bearing unit 24 with the roller 25, the housing 26 of the bearing unit 24 is rigidly fastened to a rod 27 of the cylinder 28 and has the possibility of axial movement along the axis of the processing in the guides 29.

The device operates as follows.

Mehet last so that the cylindrical end of the workpiece, designed for seaming, is inside the annular inductor. Is heated end of the preform 2, after which the mechanism 6 to move the annular coil 5 moves the latter to the right (Fig. 1), releasing the workpiece 2 to move in the tray 3, located on the axis of the processing installation. Then, using stalkivatel 7 of the workpiece 2 is served in the mechanism 9 of the clip and push the clip of the workpiece 2, and then include the rotation of the front headstock 10 and its associated spindle (not shown) of the clamping mechanism and ejection. This is possible because at the end of stalkivatel 7 rotating head 8. After spin-up spindle with the workpiece 2 satellitel 7 with rotating head 8 is moved to the right (Fig. 1) in the original position, releasing space for closing the filler neck. The sealing cap of the container is carried out for the three transitions.

The first transition is performed by the movement of the supporting roller 11 at an angle to the axis of the treatment, thus deform the cylindrical section of the workpiece 2 in a conical (Fig. 2). Movement is effected by means of hydraulic cylinder 17, the piston rod 18 through which the rack 19 is rigidly scriblerian 22, which carries out directly the deformation of the end of the workpiece. When receiving a smaller outer cone diameter equal to the outside diameter of the cylindrical end cap, the mechanism supporting roller 11 stops automatically with the command from the destination switch, not shown) and remains in this position until the end of the seaming cap, carrying out constant back pressure deformable section of the workpiece.

The second transition is the mechanism forming roller 12 mounted on the rotary plate 16, while the bearing unit 24 with the roller 25 to move along the axis of the handle at a distance l from the center of rotation (Fig. 3) that provides the necessary separation of degrees of deformation in the sealing thin-walled cylinders. The movement carried out by means of hydraulic cylinder 28, the piston rod 27 which is rigidly connected with the housing 26 of the bearing unit 24 placed in the guides 29. Then perform the rotation plate 16 (Fig. 1) mounted on the mechanism of the forming roller 12 relative to the center of the turn angle of 55-60aboutwhile receiving core and a cylindrical neck areas with intermediate sizes. Then the rotary plate 16 with the mechanism forming the role of the roller 25 is moved along the axis of the handle to the left to the top of the roller 25 coincides with the center of rotation (Fig. 3), followed by rotation of the plate 16 with the mechanism of the forming roller relative to the center of rotation at an angle of 60aboutthus the final size of the profile and cylindrical sections of the neck. Then the support mechanisms 11 and 12 forming rollers return to its original position to stop the rotation of the spindle (not shown) with a finished cylinder 14, carry out the brakes and pushing out of the bottle on the tray 3 resetter 4. When triggered, the resetter 4 tray 3 is rotated and the finished container 14 slides in the tray 13 discharge under its own weight. This cycle of operation ends. To improve the performance of the heating installation of the next workpiece under the sealing occurs simultaneously with the process of seaming the neckline, making the heating time is not included in the cyclic time, therefore, improves the performance of the installation.
