Abstract

The invention relates to the processing of metals by pressure, in particular to devices for rolling cans, and can be used in various fields of engineering. The purpose of the invention is to expand the functionality by providing roll-in of tin cans of various shapes. On the central axis 11 of the device, a carousel is installed in the form of a cross 12 with spring-loaded crackers 15, in which the axes of 16 rolling rollers (OP) 17 are located. OP 17, through kinetic coupling, interact with the sealing rollers 22, which carry out the process of rolling the bottom of the can . The trajectory of movement of the seaming rollers 22 through the OP 17 is set by a copier 9 mounted on a lifting and lowering table 7, made in the form of a frame with an inclined working surface facing the central axis 11. The device is operated during the moments determined by the cam mechanism 2-4. connected with a lifting and lowering table 7.

Description

The invention relates to the processing of metals by pressure, in particular to devices for rolling cans, and can be used in various fields of engineering.

The purpose of the invention is to expand the functionality by providing roll-in of tin cans of various shapes.

FIG. 1 shows the proposed device, a vertical section; in fig. 2 is a view A of FIG. 1; in fig. 3 - cam lifting and lowering roller.

A device for rolling cans comprises a housing 1 with a cam roller 2 mounted thereon with cams 4 on which the spring-loaded rollers 5 are supported 6

lift-lowering table 7, on which a copier 9 is fixed with the help of columns 9. Columns 8 in the case 1 have supports 10 for reciprocating movement in a vertical plane. On housing 1, a central axis 11 is fastened, on which, using a bearing unit, a crossbar 12 is installed with the possibility of relative rotation. On axis 16, a rolling roller 17 is located with the possibility of relative rotation, which with its conical surface rests on the working surface of copier 9, which is an internal closed inclination 18. The stationary axis 11 ends with a fixing unit 19, in which the can shell 20 is installed with the bottom 21 attached to it, which is subject to rolling. On each axis 16, a seaming roller 22 is also rotatably disposed with a mechanism 23 for its adjustment in the horizontal plane relative to the roll edge of the bottom of the can 21. On the bearing assembly of the crosspiece 12, a gear wheel 24 is fixed, which is connected with the drive 25 of the rotation of the crosspiece.

Device for seaming hard cans works as follows.

At the moment when the rollers 5 are located in the zone, i.e. when the lift-and-lowering table 7 is at rest, the can with the bottom 21 attached to it is fed from the conveyor (not shown in Fig.) to the fixing unit 19 and pressed against the clamping mechanism (not shown in Fig.). Then the lifting of the lifting and lowering table 7 begins with the cam 9 in the direction of the arrow B. Raise along arrow B, the cam 9 acts with its inclined surface 18 on the conical surfaces of the rolling rollers.

17 and through them move the crackers 15 from the periphery of the cross 12 to the center. Thus, each seaming roller 22 approaches the center and, with its working surface, acts on the bottom edge.

0 21, rolls it on the side of 21 cans.

After that, the rollers 5 fall into the lowering zone of the cams 4, the lifting and lowering table 7, lowering in the direction opposite to the arrow B, release the rolling rollers

5 17, as a result of which the crackers 15 under the influence of the springs 14 are pressed from the center to the periphery of the cross 12. Thus, each zakatochny roller 22 comes out of contact with an already rolled up can.

0 The rollers 5 at this time again fall into the zone of cam 4, the rolled-up can is removed from the fixation unit 19, and the next canister is fed in its place, and the cycle is repeated.

5Zona cam 4, i.e. central

the angle “at which the radius of the working surface of the cam 4 is constant is chosen such that during the time when the seaming rollers 22 are removed from the fixing unit 19 and

0 periphery, the removal of the rolled up jar and feeding the next jar to its place occurred

In a specific embodiment, a device is shown in which the working end of the copier 9 has a square shape and is intended for rolling square cans in sections. Replacing the copier 9, you can roll up cans with any device on this device, including those with a round section.

0 Advantageously, the proposed device consists in expanding its functional capabilities and in its universality, i.e. can be used for seaming rigid cans

5 forms, while such a device can be easily rebuilt by rolling cans of another shape.
