Abstract

The invention relates to welding, in particular to devices for assembling and welding shell tanks and bottoms. The purpose of the invention is to improve the performance of the device. The device contains units for transporting products, a tilter mounted on the bases of the swivel brackets, the axis of rotation of which are located below their working surfaces, with faceplates, in the grooves of the guides of which the fingers are mounted, mounted on the swivel brackets. Each swivel bracket is provided with stops - fixed for the bottom and movable for the shell, which, when pressed, ensures its passage through the bottom. The units for transporting the product are autonomous, the units for moving the tilter are made lifting, for example, from the power cylinders, and the units for moving the product on the working surface of the swing arm are led away from the product. The grooves of the guide plates are curved. Thanks to this design, the quality and productivity are improved, and the bottom is reliably and conveniently oriented on the faceplates. 1 hp ff, 6 ill. v

Description

The invention relates to welding, in particular to devices for assembling and welding shell tanks and bottoms.

The purpose of the invention is to improve performance.

Fig. 1 schematically shows a device for assembling and welding tanks from a shell and bottoms; general form; figure 2 - node I in figure 1; FIG. 3 shows the place of attachment of guides to the brackets; figure 4 is a view of the drive roller; Figure 5 shows the place of attachment of the bottom to the faceplate; fig.b is a diagram of the position of the bracket.

The device for assembling and welding tanks comprises frame 1 mounted on the base, drive 2, roller supports 3 on which ring tiller 4 is installed. Under transport ring 4, transport units are installed to roll in tilter 4 of the shell 5 and roll out the assembled product, made in the form of lifting rollers 6 with power cylinders 7. To the left and to the right of the annular tilter 4 on the bases 8 in the guides 9 are mounted with the possibility of horizontal movement from the power cylinders 10 movable carriages 11. N And the bases 8 are mounted on the axes x 12 by swivel brackets 13 with faceplates 14, on which they are fixed by pressing

about

Bottom 15, with the axis 12 of the swivel brackets 13 are located below the working surfaces of the swivel brackets 13. On each swivel bracket 13, support units 16 are fixed and the bottoms 15 are pressed by pressing the power cylinder 17, the rod of which is connected to the faceplate 14. Each support unit 16 consists from the fixed stop 18 for orientation of the bottom 15 and the movable stop 19 with the axis 20 and the return spring 21.

The plates 14 are provided with guides 22 with slots 23 and 24, which are curved and in which fingers 25 are mounted on rotary brackets 13 and providing the center of the bottom 15 on the horizontal axis of the shell 5 / on the vertical axis during pressing. shell 5. On two sides of each movable carriage 11 there are two transportation units, made in the form of roller bearings 26 and serving to roll the shell 5 into the ring tilter 4. Each outgoing drive roller 26 consists of Considerations 27, which are fixed in the form of parallelogram lever 28 associated with the platform 29 and ram 30 is installed, providing the outlet and inlet to the sleeve 5 driven carrying rollers 26. The platform 29 is mounted with the drive roller 31, 32 to ensure transportation of the sleeve 5.

The device works as follows.

The shell 5 along the driven roller supports 26 and the lifting wheel supports 6 rolls into the turner 4, the passage above the faceplate 14, the movable carriage 11. The lifting roller supports 6 are lowered and the roller supports 26 are retracted to the sides, allowing the movable carriage 11 to move in a horizontal direction.

On the faceplate 14, which is in its original horizontal position, the bottom 15 is mounted on the fixed stops 18, while the stops 19 are divorced under the weight. Then the faceplate 14 is rotated by the power cylinder 17 to a predetermined angle. The movable stops 19 are released and under the action of the springs 21 are reduced by an amount guaranteeing a reliable stop s the end of the shell 5. After that, the swivel bracket 13 with the faceplate 14 and the bottom 15 is rotated to the vertical position, the horizontal movement is communicated to the movable carriage 11, and the bottom 15 with the faceplate 14 are inserted into the shell 5 at a predetermined size h.

Then the power cylinder 17 is turned on, and the face plate 14 with the bottom 15 is moved to a vertical position. In this case, the curved grooves 23 and 24 of the guides 22

The faceplates 14, in which the fingers 25 are located, provide a predetermined bottom pressing path, i.e. the center of the bottom remains on the horizontal axis, and the lower point moves vertically down. With such a pressing movement, the bottom 15 presses the movable stops 19.

At the end of the press-in, the bottom 15 is released, the movable carriage 11 rolls back, the plate 14 with a swivel

5, the bracket 13 is returned to its original position, and the assembled product is turned by the tilter 4 on the roller couplers 3 and welding is performed. After welding, the rollers 6 are lifted, roller pores 26 are brought together, and the assembled product is removed from the turning device 4. Then the cycle repeats.

The proposed device in comparison with the known improves the quality and performance of the Assembly and welding,

5 provides the mechanization of the transportation of products, reliable and convenient orientation of the bottom on the faceplate with additional mechanical fastening, ensures the process
