For this purpose, on the splines of the shaft 76 install the movable gear 77

Copiers 42 are made interchangeable with a drive 78 to move it, gear 23 is fitted with gear 79, gear 34 is driven mobile with 80 drive power and gear 81, and free rotating gear 82 is installed on its hub.

The device is also equipped with a gear unit 83, co-operation with gears 34 and 82 and gear 77 (Fig. 11).

The machine works as follows.

In order to manufacture the casing (housing) of the fan of the main construction (Fig. 9 and 10), the machine is adjusted to the width of the welded frame size of the housing and is completed with the corresponding face plates 51 and copiers 42.

In the initial position, the faceplate 51 by the actuators 46 and 49 is placed in a horizontal position (Figs. 2 50 and 4). In this case, the gear 58 of the shaft 57 is engaged with the gear 35 of the roller rollers 30 connected by the coupling 31 with the drive 24 through gear 34, and The faceplates are prepared 55 for rotation and for laying the side walls 9 and 10 on them. The side walls laid on the faceplates are completed with stud bolts 72 (and with the input flanges of 73 body structures

The machine also contains replaceable welding heads and guide rollers for the inner surfaces of the side walls and for welding internal solid or assembly seams (not shown). The fan casing includes a lining 3, side walls 9 and 10, bolts .72, inlet flange 73, reflector 74 and flange 75.

flange) for welding them with intermittent ring seams (Fig. 5). .

Sheet-lining 3, usually pre-welded on a multi-part contact machine, is laid on the roller table 2, and the head unit is set to its initial position for rolling. To do this, with the clutch 31 off, the rollers 30 are driven by a drive 2A, the copiers 22 connected to the drive rollers by the shafts 28, gears 26 and 27 and the clutch 25 to the position of the pressure rollers 12 moved by the rods 16 and 17 and the rocker arms 15 to the position corresponding to the perpendicular position of the straight line passing through the axes of the rollers 12 and 18 to the horizontal plane passing through the contact line of these rollers (angle V-cL). Then, sheet-covering 3 is rolled on section 1 with copiers 22 turned off by coupling 25, as well as simultaneous welding of bolts 72 with side walls 9 and 10 (Figs. 3 and 5). To do this, include the clutch 31 rotation of the rollers 30, rolling sheet-lining under the profile with curved edges (Fig. 11 and 12). Section 1 moves between drive 18 and pressure rollers 12, as well as above rollers 6 installed by drive 40 at roller ’level 18. When lining the end of the casing sheet, spun by length 1, with end switch 68, clutch 25 and copiers 22 rotated by gear 23 , the rollers 12 are moved relative to the rollers 18 and 6, providing a joint with the rollers 6 driven by the drive 40, further rolling the sheet-covering with a variable radius. Adjusting the length of t g 16 allows adjustment of rolling with a variable radius, as well as setting up an automat to produce the appropriate frame size of the fan casing.

The rolled-out sheet 3, the end of which interacts with the switch 69, stops and is fixed in the clamping device 14. The switch 69 includes the drive 13 for the pressure rollers 12 and the drive 39, whose shoe 38 presses the end of the cover sheet to the pad 37 (Fig. 3, 4 and 6) and the rollers 12 are retracted from the rotating drive ros.

18. The copiers 22 are then disconnected by the clutch 25 from the rollers 18.

Bolts 72 with side walls 9 and 10 are welded simultaneously. with rolling sheet-covering and after rolling. The horizontally mounted faceplates 51 with side walls are turned to the position of welding of the next bolt 72 by turning on the coupling 65 connecting the gear unit 62 to the gear 63 mounted on the brake drum of the faceplate 51.

The clutch 65 simultaneously disengages the electric brake 54 and the faceplate with a gear consisting of gears 58 and 61 and a shaft 57 connected by gear 35 to the rollers 30. The rotation of the faceplate is stopped when the first welded bolt of the switch 70 interacts, disengaging the sleeve 65 and including electric brake 54 (Fig. 5). After welding, the bolts 72 of the faceplate 51 are installed by the actuators 46 in a vertical coaxial position, with the gear 58 disengaging the gear 35, and the gears 59 and 64 engaging to rotate the faceplates in a vertical position, in this case for orienting the lateral the walls 9 and 10 and fixing them in position for welding with the sheathing 3. The faceplate is rotated with gears 35- and 59-64 and shafts 56 and 57 activated by sleeve 65.

The orientation of the side walls ends when the rectangular portion of the rotating side wall interacts with the switch 71,

disconnecting the clutch 65 and including a faceplate 54, 51 (Fig. 5 and 9). Orientation of the side walls can be carried out and 45 in the horizontal position of the faceplate. Before orientation of the side walls mounted coaxially, if necessary, welding of the inlet flange 73 is intermittent

using the drive 13. The junction of the sheet-covering and the reflector 74 is welded semi-automatic.

The side walls 9 and 10 dock with the skin-sheet and the reflector 74, for which the actuator 49 rotates the manipulator 8 until the ends of the side walls come into contact with the bent edges of the skin-sheet 3 and with the reflector 74 (Fig. 1). The copier rollers 45 are driven by the actuators 46 into contact with the copiers 42, while the rollers 45 together with the manipulator are pressed against the copiers 42 by a certain force of the actuator 49 mounted on the adjustable presser (Fig. 2).

The copiers 22 of the tracking device are in the stop position after rolling the common sheet with a variable radius, which corresponds to their initial position for rotating in the opposite direction to crimp the edges of the skin sheet and weld them to the side walls. The side walls 9 and 10 are welded with internal seams with a semi-automatic reflector 74, while the rollers 20 for crimping the edges of the skin-sheet are installed by the actuators 21 in the working position (Fig. 12), the roller rollers 30 are disconnected by the coupling 31, and the copiers 22 are connected by a coupling 25 seconds drive rollers 18.

By rotating the drive rollers 18 in the opposite direction, crimping is performed, and welding the edges of the skin-sheet with the side walls with intermittent seams produces welding heads 41 or semi-automatic machines.

At the same time, the camcorder using the copiers 22 provides the position of the rollers 12, pressing the ist-lining 3k to the rollers 18, corresponding to the variable curvature of the casing and the position of the rollers 20 for crimping the edges of the plating sheet in a single continuous process associated with simultaneous conjugation of the side walls - trimming using copiers 42 in the weld zone.

After welding the sidewalls with the skin-lining, the product to be welded is placed in the position for joining and welding the output flange 75. To do this, set the manipulator to the position 0 by the actuator 49 (FIG. 1) and rotate the casing of one gear to rotate the face plates 51 to

convenient position where the flange 75 is mounted and welded to the fan casing. The manufactured housing is removed by releasing the chuck clamps and wiring them with the actuators 55 and 46. Then the cycle is repeated.

Fabrication of cases with thick side walls 9 and 10 (more than 3 mm) can be made using. drive 49 only. The proposed automaton is intended for the manufacture of casings with thin side walls (2.5 mm or less) that reduce the metal capacity of the hull structure.

In the manufacture of construction casings (Figs. 13 and 14), the skin is rolled only by a variable radius of rolling (without bending the edges, for which only cylindrical rollers 67 of cylindrical shape and side rollers are used) (not shown), and the profile rollers 66 are retracted to the sides (Fig. B).

To manufacture covers without pressing the edges of the skin sheet (Fig. 13), the machine is completed with a trolley and inner guide rollers for the side surfaces of the side walls (not shown), and the rollers 20 are used as outer guide rollers and also provided with inner welding heads .

The manufacture of cases (Fig. 14) is carried out by advancing mon0.

heavy welding of side walls 9 and 10 with sheet-covering 3 welding heads 41 and the subsequent imposition of the main seams on the mounting tacks (semi-automatic or other method). In so doing, welding heads 41 with a pulsed electrode feed are used, as well as a drive 40 of the table 5 (Fig. 7). Assembly welding of the side walls with the sheet is also possible with intermittent internal weld head welding, mounted on a trolley (not shown). The rollers 20 for crimping are used in this case as clamping rollers for the outer surfaces of the side walls, which are pressed during mounting clamps to the ends of the skin-sheet 3.

When changing the machine to iz-, the preparation of a different size of housings, the gearbox 23 is switched to the gear ratio corresponding to the ratio of the number of revolutions of the drive rollers 18 moving

for the welding cycle, this length of the skin sheet, to one revolution of the shaft of the copiers 22 and 42.

For greater flexibility of the machine, a variable speed variable speed variable transmission can be used as the gearbox 23. I. When welding the fan casing using it to turn the copiers 22 and 42, the device works as follows.

Drive 80 drives gear 82 into engagement c. the gear unit 35 and 64 and the gear unit 83. In this case, the rollers 30 are turned off (including the clutch 31). The initially mounted shaft 76 with the copiers 22 and 42 is connected by a drive, 78 to the gear 83, and the faceplates 51 connect the coupling to the 2 heads, and the manipulator, to the full 65, to the gears 59 to 64 and the shafts 56 and 57. The rotation of the rollers 18 rotates and welds the fan casing, while the copiers 22 and 42 control the position of the rollers 12 and 20 by matching the welded edges of the skin-sheet and side walls in an automatic, dependent on the casing rotation mode.

The proposed method produces fan housings, the strength of which ensures the transmission of torque to the shaft 76 without slipping and the possibility of deformation of the side walls. The nomenclature of the nonstandard curvature of the ZTsS-17 and TsS-34 type fan housings used in the shipbuilding industry30 is significant.
