The invention relates to the field of welding, namely to the design of an apparatus for assembling joints of sheet blanks for welding, preferably electron beam.

The aim of the invention is to improve quality by reducing the deformation of sheet blanks when assembling them for welding.

FIG. 1 shows the installation, a general side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. 2

The device for assembling the joints of sheet blanks for welding, mainly electron-beam, contains a support frame 1 mounted on the base,

ten

The drive of the carriage 5 is turned on and it begins to move along the working table 2 to the right towards the sheet blank 28, as a result of which the lower plane e of the sheet blank 28 is placed on the plane of the support bar 25, and the end e abuts against the plane e of the support bar 26. At the same time When the carriage 5 moves, the copier roller 19 passes the copier 4 and when it comes into contact with the plane in the copier 4 under the action of the spring 23, the axis 22 moves along the guide groove 24 to the stand 8 and, therefore, together with the axis 22 shifters; and so how m ha

which is installed desktop 2 with supports-. 21 is fastened by a driver 18, on which the rollers 3 are mounted. The lever 16 of the presser 7 is installed, then the co-fier 16 rotates on the working table 2 downward about the axis 17

Feast 4. and presses the sheet blank 28 to the plan B of the support frame 1 is installed with a hook 26. At the same time, its movement is ensured for transporting the sheet blanks for 28 seconds.

vanilla sheet blanks carriage 5 with a support - 20 wide range of thickness S. Noah plate 6. On the support plate 6 Further movement of the carriage 5 along

located in the housing are the clamp 7, the stand 8, the proximity sensor 9, the copier 10, the housing 11, the guides 12 and the rollers 13.

The housing 11 of the clamp 7 is interconnected with the rack 8 by the spring 14.

Desktop 2 occurs in conjunction with the sheet blank 28 fixed in the clamp 7.

When the stops 27 reach the front end of the sheet stock 28, the drive of the carriage 5 continues to work and, due to this, the spring 14 begins to compress. When spring 14 is compressed

On the housing 11 of the clamp 7 is mounted strap 15.

The clamp 7 contains a clamping element

16, made in the form of a rotary ryv- -, „with. Displacement of the support plate 6 of the carriage 5 of the chaga. Relative to the pressure body 11, i.e

moving the rollers 13 along the guides 12.

When this strap 15 is included in the zone of action of the contactless sensor 9, and the copier W begins to interact with the roller

chaga.

The clamping element 16 is mounted in the housing 11 by means of a hinged axis 17 and interconnected with the leash 18. On the non-working arm of the lever on the leash 18

posted copy rollers 19 and 20. -ZS - --- - -

The leash 18 is fastened with a pull of 21, which is 20. As a result of the interaction of the roller 20

pivotally interconnected with the axis 22. The axis and the copier 10 leash 18 is lowered, and the market through the springs 23 connected the shaft 16 is rotated around the axis 17

8. The axis 22 is positioned in the directionally and sheet billet 28 is released, which fits the groove 24 of the pressure housing 7. So that it only acts

On the body of the clamp 7 is fixed 40 longitudinal force from contact with the support bar supporting strips 25 and 26, and the flat plate 26, which prevents the sheet billet from warping due to the influence of the clamp 7. At the same time, during the interaction of the proximity sensor 9 and the strip 15, the spring 14 continues to compress, balancing the pressure force of the carriage 5 onto the sheet blank 28, as a result of which the end face of the sheet blank 28 presses tightly against the stops 27, which ensures a high ratio of the bracket 5 to the left Well along the line of position. Welding. The contactless sensor 9 of the roller, 19, is located on the plane inlet, the drive of the carriage 5 is turned off,

On the worktable 2, there are mounted retractable stops 27 located along the welding line. Sheet harvesting is indicated by the position 28.

A device for assembling sheet blanks for welding, mainly electron-beam, operates as follows in PN1.

The sheet stock 28 is fed to the worktable 2.

After that, the drive of the carriage 5 is turned on. The support plate 6 of the carriage 5 begins to move to the left, the copier 10 you

The drive of the carriage 5 is turned on and it begins to move along the working table 2 to the right towards the sheet blank 28, as a result of which the lower plane e of the sheet blank 28 is placed on the plane of the support bar 25, and the end e abuts against the plane e of the support bar 26. At the same time When the carriage 5 moves, the copier roller 19 passes the copier 4 and when it comes into contact with the plane in the copier 4 under the action of the spring 23, the axis 22 moves along the guide groove 24 to the stand 8 and, therefore, together with the axis 22 shifters; and so how m ha

wide range of thickness S. Further movement of the carriage 5 along

Desktop 2 occurs in conjunction with the sheet blank 28 fixed in the clamp 7.

When the stops 27 reach the front end of the sheet stock 28, the drive of the carriage 5 continues to work and, due to this, the spring 14 begins to compress. When spring 14 is compressed

C. displacement of the support plate 6 of the carriage 5 relative to the body 11 of the clamp 7, i.e.

After that, the drive of the carriage 5 is turned on. The support plate 6 of the carriage 5 begins to move to the left, the copier 10 leaves the zone of contact with the roller 20 and the lever 16 presses the welded sheet blank 28 to the support bar 25.

A further reverse movement of the carriage 5 is carried out jointly with the welded sheet stock 28, thus withdrawing it from the working zone of the vacuum chamber.

When the copying roller 19 reaches the copier 4, the lever 16 is raised and the welded sheet blank 28 is removed from the working table 2.

The use of the invention provides improved quality by reducing the deformation of sheet blanks when assembling their joints for welding.
