(54) DEVICE FOR DIRECTION OF SHUTTER TILES IN THE SEAMWORK PROCESS

(57) Use: welding production, in contact welding of longitudinal seams of the shells. The invention: the device contains the bottom

beam 1 and top beam 2. Roller blocks 4 are placed there with grooves E for positioning the respective edges of the shell. The beams are installed with the possibility of relative movement in the horizontal plane, which allows adjusting the amount of overlap of the edges of the shell. Flaps are mounted on the beams. Each flap is installed with an overlapping groove of a roller located on the same beam with it. This ensures that the edge of the shell is clearly inserted into the groove of the opposite roller. The device eliminates the rapid wear of the slots along which the edges of the shell slide. 2 Il.

The invention relates to equipment for resistance welding and is intended for use in welding technology, for example, in contact welding of longitudinal seams of shells with edge crushing or low overlap.

A device for guiding the edges of the shell in the seam welding process, comprising lower and upper beams, facing each other, the surfaces of the tires are provided with inserts, in the body of each of which there is a groove with an inlet surface for accommodating the corresponding edge of the shell.

The drawback of the device is the rapid wear of the grooves along which the edges of the shell slide, which leads to a deterioration

quality welds, frequent replacement of liners.

The aim of the invention is to improve the quality of welding and productivity by increasing the durability of the device.

FIG. 1 shows the proposed device; in fig. 2 shows section A-A in FIG. one.

The device for guiding the sides of the shell in the seam welding process consists of a lower beam 1 mounted on the console of the machine’s lower welding roller and an upper beam 2 mounted on a special console 3 on which the blocks of rollers 4 with annular grooves are installed E. The rollers are mounted on axles 5, bearings 6, which are installed between retaining rings 7 and 8. The axles are fastened with nuts

9. The beams are mounted on insulating gaskets 10 and have plates 11 with inclined surfaces K fixed with screws 12. Beams with blocks of rollers are mounted with the possibility of displacement relative to each other. The magnitude of the displacement e determines the amount of overlap of the welded edges of the rim 13.

The device works as follows.

When the upper welding roll is retracted, the shell 13 is inserted with its edges into the grooves E of the rollers 4 installed in blocks in a row on the lower beam 1 and the upper beam 2. When welding (the upper welding roll is lowered) the edges of the welded shell move between the welding rollers They are pressed to the bottom of the grooves with the force required to hold them during welding, and as the rollers rotate, the wear of the grooves will be minimal.

Functions pos. 11 are to ensure that the edges of the welded shell are well within the grooves E, i.e. the flap 11 fixed on the lower beam 1 overlaps (protects) the profile of the lower row of rollers so that the edge of the shell 13 (on the right) does not accidentally fall into the grooves of the lower row of rollers. Similar functions are performed by a flap attached to the top beam.

The described device provides a constant overlap of the edges being welded.

due to the lack of wear of the grooves of the rollers when rolling edges along them during welding; provides control over the amount of overlap, due to the displacement of the lower and upper beams relative to each other; provides increased productivity.

Claims (1)

An apparatus for guiding the edges of a shell during seam welding, comprising lower and upper beams facing one surface of which are provided with inserts, in the body of each of which there is a groove for accommodating a corresponding edge of the shell, characterized in that in order to improve the quality of welding and labor productivity by increasing the durability of liners, the latter are made in the form of rollers mounted on the beams with the possibility of rotation, the grooves for placing the edges of the shell are the number coaxial with the rollers, and the beams are mounted with relative displacement in a plane perpendicular to the rollers, and provided with shields, each of which is installed with an overlap of the groove located on the same roller beam, in order to clearly hit the corresponding edge of the shell of the roller.
