BACKGROUND OF THE INVENTION The present invention relates to an additional device for a sheet-bending machine in which the carrying of a wrapping sleeve is pushed onto a bending roller of the machine, supporting and resiliently disengaging the circling after the rollers of the roll bending machine and the manipulation of the ring

So far known three-cylinder, four-cylinder and two-cylinder bending machines are not equipped with such additional equipment. The bending process and the quality of the circles then depend mainly on the design of the machine, the diameter ratio of the rollers, the axial distance of the supporting rollers, and other factors.

When bending on double roll bending machines, the ring is often deteriorated by folding the ends of the sheet blank with subsequent rolling between the rollers. After the roll bending rollers have been removed, the ring occupies a position which allows the bending machine to be arranged, at the two roll bending machine at least two indeterminate positions, reduces handling and prevents automation of the ring manipulation.

The aforementioned drawbacks are eliminated by the additional device according to the invention, which can be mounted on each sheet bending machine, provided with a wrapping sleeve of the respective diameter, which is pushed up by a machine bending roller.

The essence of the additional device according to the invention is that it consists of a tensioning device for maintaining the contacting of the packaging sleeve and the bending roller of the roll bending machine and the ball-bearing support device for supporting and expanding the curvature, both of which are removably mounted on the axis of the bending roller beyond -kružovacky.

The tensioning device is formed from two clamping bodies symmetrically slid over the extending ends of the upper bending roller axis of the bending roller, over which cross-height adjustable adjusters are provided over the guides by means of adjusting means which are connected in the horizontal direction by a connecting rod on which the va-hoses are rotatable between the crossbars. provided with symmetrically supported rollers coated with an elestomer layer, the fixing of the clamping bodies of the tensioning device at the ends of the axis of the upper bending roller being transferred by clamping screw connections and locking by a locking element.

The support device is formed from two clamping bodies slid onto the protruding ends of the upper bending lobe from the outside of the clamping bodies of the tensioning device, over which a horizontally arranged transverse guide plate is arranged over the cylindrical guides, the ball-shaped symmetrically arranged bead-like adjustment means in the transverse guides. paths with ball units whose horizontal connection is transferred by expanding means, the fastening of the clamping bodies of the support device of the axes of the bending cylinder being transferred by screwed clamping connections and the locking by the locking element. The tensioning support of the tensioning and supporting device is advantageous to be carried out as one. The additional device according to the invention exhibits new and higher effects by extending the technological possibilities of the benders by allowing bending with a calibrator of the truffle, allowing the bending of the sheet with first cut openings without limbs and weakened cross sections, improving the quality and repeatability of the production especially on the twin rollers. that allows to operate in machine mode with the contact area of the encircling ring and encapsulation, thereby eliminating the influence of the operator of the machine, preventing the transfer of the lesions of the lesion and thereby preventing the disc curvature from being invalidated, providing a defined positioning complete of the circle after the rollers, thereby enabling the manipulation of the sausage. curlers.

In the accompanying drawings, there is an example of an additional device for a roll bending machine, wherein in Fig. 1 is a view of the axis of the rollers of the additional device arranged in the over-cylinder bending machine in Fig. 2 is a partial cut-away side view of the additional device in Fig. 3 . 3 249473

Fig. 4 is a cross-sectional view taken along line A-A of Fig. 2, showing a front view of the tensioning device of the additional device to the bending machine. Fig. 5 shows an arrangement of an additional device on a three-cylinder symmetrical bending machine in axial view and in Fig. 6 an arrangement of the same additional device on a four-cylinder bending machine. An additional device for a shoulder bending machine (FIG. 1). 1 / consists of a tensioning device 4na maintaining contact of the packaging sleeve 2 with the bending roller 2 of the roll bending machine and the support device 5 with ball tracks provided with ball units 51 applying the ring 2, both of which are removably mounted on the axis ± 6 of the bending roll . The tensioning device 4 / fig. 4) is formed from two clamping bodies 41 symmetrically inserted on the protruding ends of the bending roller axis 6, over which cross members 42 arranged vertically adjustable by means of adjusting means 41, which are connected in a horizontal direction by a connecting rod 45 / fig. 2 / on which the rockers 46 / fig. 4 (provided with two symmetrically supported elastomer-coated rollers 47), the fastening of the clamping bodies 41 of the tensioning device at the ends of the folding roller axis 6 is transferred by screwed clamping joints 48 and the safety locking element 49.

The support device 5 / FIG. 1 to 3/2 two clamping bodies 57 are inserted slid over the extending ends of the bending roller axis 6 from the outside of the clamping bodies 41 of the tensioning device, above which a transversely aligned plate 54 / fig. 3 / height adjustable in guides 55 / fig. 1 / adjusting element 56, on which the ball track bodies 52 with ball units 51 are arranged in the symmetry guides 59, the horizontal connection of which is provided by the filling means 53, the fastening of the support bodies 57 of the support device at the ends of the bending axis axis 6 being transferred by screwed clamping joints 58.

The clamping bodies 41, 57 of the tensioning and support device are preferably converted into one.

The puncture of the additional device to the plate bending machine is followed by the mass production of the cylindrical shells of the given diameter on the bending roller 10 / fig. 1 / engages the respective packaging sleeve 2, which is tensioned by the tensioning device 4 over the pulleys 47 so that the contact of the cylinder 1 with the inner surface of the packaging sleeve 2 is ensured even after the machine rollers have been spaced apart.

The pulleys 47 mounted on the rocker arms 46 allow the wrapping sleeve to assume a machine-positioning position at work and, after the rollers have been moved away, to secure the bending roller 1 and the powder 2. The ring 3 produced is continuously wound onto the support device 6 provided with ball units 51 and arranged with the filling means 53 to be flexible. unrolled, and after complete rounding, the ends of the sheet were not folded, followed by rolling.

In addition to this function, the carrier device 51 allows the cord to retract the ring from the bending roller J. by hand or by means of a manipulator, since the weight of the ring rests on the bead units. bending machine / fig. 5 (with symmetrically supported support rollers 7, 8) or a four-roll bending machine / fig. 6 / with pressure roller 9 and support rollers 16, 11.
