The disks 87 and 88 are mounted on a separate sleeve 91 (Fig. 12), which can be fixed with a screw 92 on the spindle 4 (Fig. 10) in any angular position. In addition, the disks 87 and 88 can rotate relative to each other on their hub 91 (Fig. 12), i.e.

fix it in any angular position when turning it. By rotating this eccentric, the depth of stripping of the insulation is controlled. The levers 51 (Fig. 6) are also attached to the spring 62, which other end is fixed on the strap 63 mounted on the screw 64 mounted in the housing 49 of the mechanism. With this screw, by stretching the spring 62, the force with which the grooved rollers 53 are pressed against the multicore flat wire is changed.

The cutting unit is installed in the frame 14 (Fig. 5) on the axis 65. The fixed knife 67, the movable knife 68, the toothed sector 69 and 5 of the two shoulders of the pawl 70 are located in the cutting assembly case 66.

The disks 85 and 86 are installed on the sleeves 89 (Fig. II), which are freely mounted on the spindle 4 (FIG. 10) and with the help of screws 90 (FIG. 11) can be fixed on it in any angular position. The disks 87 and 88 are mounted on a separate sleeve 91 (Fig. 12), which can be fixed with a screw 92 on the spindle 4 (Fig. 10) in any angular position. In addition, the disks 87 and 88 can rotate relative to each other on their sleeve 91 (Fig. 12), thereby changing the width of the notch 93. On the disks 85 and 86 (Fig. 10), the width of the notch is constant. The disk 85 (FIG. 4) is inserted into the groove of the sensor 94, which serves to count the current number of turns of the winding coil and is connected to the input of the counting device, it has two outputs. One of the outputs is connected to the input of the control circuit of the winding head motor, and the other at the same time to the inputs of the control circuits of the brake pneumatic cylinder, the stripping motor, the stripping electromagnets. The disk 86 enters the groove of the sensor 95, which serves to simultaneously turn on the motor of the insulation stripper and the spool of the brake pneumatic cylinder and is connected to the inputs of the stripping motor control circuits and the brake pneumatic cylinder.

In addition, on the spindle 4 (Fig. 10) there is a brake pulley 97 and a fixing disk 98 with a groove. There is also a brake lever 99 (Fig. 13) with a brake pad 100. This lever is pivotally mounted in the winding head housing 81 and connected to the spring 101. In the brake lever 99, a rod 102 is installed, which can freely move along its axis in it. On the stem 102 is placed a spring 103 and a nut 104, which regulates - dd with the force of this spring. The rod is located between the brake pneumatic cylinder 105, fixed on the frame I, and the adjusting screw 106, mounted on one of the arms of the locking lever 107, pivotally

25 springs 24 (Fig. 3) to the extreme upper position. The housing of the lower electrodes (Fig. 5) by turning on the axis 28 counterclockwise will move from the winding coil 5 to the extreme right position. The angular lever 34 in this case abuts one of the shoulders into the frame 14, and the dog 39 is above the protrusion 111 of the angular lever 34.

Case 66 node cutting by turning it on the axis 65 clockwise retracted from the winding coil 5 to the extreme right position. In so doing, the toothed sector 69 retracts the movable knife 68 to the lowest position in which it presses the screw 74 mounted in the two shoulders dog 70, causing it to rotate around its axis and take up position above the stop 75.

The clamping roller 76 is retracted from the coil 5 by the pneumatic cylinder 79 to the lowest position.

Before work, the take-up unit 77 (Fig. 1) is set up of a coiled flat wire wound into rulovki multi-installed in the case 81. The lever is retracted from the locking disk 98 (Fig. 10) by the spring 108 (Fig. 13). A roller 109 is mounted on the opposite shoulder of the lever 107. There is also a microswitch 110 fixed to the winding head housing 81.

The machine works as follows.

When the machine is turned on, its main mechanisms take the following initial positions. Spindle brake on. At the same time, the brake pneumatic cylinder 105 (Fig. 13) first presses the brush 102, compressing the spring 103, which causes the brake lever 99 to rotate and presses the brake shoe 100 against the surface of the brake50

Lone 80. The wire 43 is unwound from the roll 80 manually and its beginning is stripped of insulation using an isolation stripping assembly when it is turned on in a setup mode. At the same time, the beginning of the stranded flat wire is placed between the corrugated rollers of the stripping mechanisms 42. Then the wire 43 is wound from the roll 80 until the stripped end thereof is under the upper electrodes 17 of the welding unit. The wire passes through the window, made in the G-shaped m lever 27 (Fig. 5), the housing 66 cutting unit and the movable knife 68. On the coil 5 (Fig. 14) set the bar 112 with the findings.

pulley 97 (Fig. 10). With its further progress, the brake pneumatic cylinder 105 (Fig. 13) rotates the locking lever 107 through the rod 102, inserts its roller 109 into the groove of the locking disk 98 (Fig. 10.) At the same time, the rod 102 (Fig. 13) moves freely in the holes of the brake lever 99, compressing the spring 103. The magnitude of the braking torque on the brake lever 97 (Fig. 10) is determined by the force of the spring 103), which

is adjusted by the nut 104.

The motor 45 of the stripping unit (Fig. 6) is turned off in the initial position, and the electromagnets 58 of both stripping mechanisms are turned on. Moreover, their 57 measles are drawn to the cores of electromagnets. Since the measles 57 are hinged to the levers 51, they force them to turn on the axles 50, and the grooved rollers 53 mounted in these levers on the bearings 52 (Fig. 7) are retracted from the multi-core

flat wire 43, which gets the opportunity to move between the rollers 53, without hitting them.

In the initial position, the housing of the upper electrodes (Fig. 5) of the welding unit is retracted from the winding coil 5 under the action of

springs 24 (Fig. 3) to the extreme upper position. The housing of the lower electrodes (Fig. 5) by turning on the axis 28 counterclockwise will move from the winding coil 5 to the extreme right position. The angular lever 34 in this case abuts one of the shoulders into the frame 14, and the dog 39 is above the protrusion 111 of the angular lever 34.

Case 66 node cutting by turning it on the axis 65 clockwise retracted from the winding coil 5 to the extreme right position.

The clamping roller 76 is retracted from the coil 5 by the pneumatic cylinder 79 to the lowest position.

Before working, a multi-core flat wire is installed in the tension-tensioning unit 77 (Fig. 1), wound in ru

Lone 80. The wire 43 is unwound from the roll 80 manually and its beginning is stripped of insulation using an isolation stripping assembly when it is turned on in a setup mode. At the same time, the beginning of the stranded flat wire is placed between the corrugated rollers of the stripping mechanisms 42. Then the wire 43 is wound from the roll 80 until the stripped end thereof is under the upper electrodes 17 of the welding unit. The wire passes through the window, made in the G-shaped m lever 27 (Fig. 5), the housing 66 cutting unit and the movable knife 68. On the coil 5 (Fig. 14) set the bar 112 with the findings.

The button located on the control panel (not shown) includes the welding unit, which operates as follows. After switching on, the cylinder rod 37 (Fig. 5) begins to move to the left. Since the straight 30 and angular 34 levers are connected by a spring 36, they begin to rotate around the axis 32 together. The dog 39 thus moves away from the adjusting screw 40 and under the action of the spring 41 rests on the protrusion 111c of the angular lever 34. The L-shaped lever 27 through the pulping 29, it receives movement from the forward lever 30 and rotates around the axis 28 until it resists the adjusting screw 31. At this moment, the lower electrodes 19 will take up the position just below the upper electrodes 17, and the movement of the L-shaped lever 27 and the straight lever 30 stops. In this case, the stopper 35 under the action of the spring 41 extends beyond the protrusion 113 made in the frame 14, and the angular lever 34 fits tightly to the roller 25. The cylinder rod 37 continues to move to the left, causing the angular lever 34 to rotate on the axis 33, stretching the spring 36. In this way, the lever 34 presses the roller 25 and forces the housing 18 to move with the electrodes 17 downward. The upper 17 and lower 19 electrodes are closed, clamping the leads 112 of the strap 112 and the insulated section of the stranded flat wire 43 between them. The upper electrodes 17 in the housing 18 move upwards, compressing the springs 21, the force of which determines the compressive force of the electrodes 17 and 19 when welding. The rotation of the angular lever 34 occurs until it resists the surface 114 of the frame 14. During the compression of the electrodes 17 and 19, the dog 39 comes over the protrusion 111 in the corner arm 34, and the stopper 35 rests against the protrusion 113 in the frame 14, It does not rotate the right lever 30 on the axis 32 in a clockwise direction.

After this, the welding current supply is switched on. After welding, the electrodes are retracted. In doing so, the cylinder rod 37 moves to the right. The angular lever 34 pivots on the axis 33 clockwise and with its protrusion 11 1, resting against the dog 39, removes the stopper 35 from engagement with the protrusion in the frame 14. The housing 18 together with the electrodes 17 under the action of the springs 24 moves to the extreme upper position. The cylinder rod 37 continues to move to the right. Since the stopper 35 has released the straight lever 30, both the levers — the angular 34 and the straight 30 — begin to rotate together on the axis 32 until the angular lever 34 rests against the surface 115 of the frame 14. During this movement, the dog 39, the abutment cushioning the adjusting screw 40, rotates on the axis 388 and disengages from the protrusion 111. In this case, under the action of the spring 41, it will take a position above this protrusion, and the stopper 35 will take a position over the protrusion 116 in the frame 14. In addition.

during the return stroke, the forward lever 30 causes the L-shaped lever 27 to rotate together with the electrodes 19 counterclockwise. Thus, all elements of the welding unit are fixed in their original position.

After welding, the bar with the leads 112 is lowered down and pulled over the ledge 113, made in the walls of the coil 5, as shown in FIG. 15.

0 Thereafter, the rotation of the spindle 4 (Fig. 10) is turned on and the coil is wound. In this case, first, the brake pneumatic cylinder 105 (Fig. 13) is activated, which moves to the extreme left position, releasing the rod 102, which under the action of

5, the spring 103 moves in the brake lever 99 all the way to the left, and then with it, under the action of the spring 101, rotates on the axle. When this brake pad 100 departs from the brake pulley 97

Q (Fig. 10), and the locking lever 107 (Fig. 13) with the roller 109 under the action of the spring 108 comes out of a groove made in the locking disk 98 (Fig. 10), releasing the spindle 4 and the microswitch 110 (Fig. 13 ), which gives the command to turn on the electric motor 2 of the winding head 3 (Fig. 3), transmitting its rotation to the spindle 4 via the belt drive 83 and the pulley 84. Together with the spindle 4, the disks 85-88 (Fig. 10) rotate. With the coincidence of the cuts made in these discs, with sensors 94-96

0, electrical signals are generated to the machine control circuit. The signals of sensor 94 (Fig. 4) are fed to the input of the counting device, which sums them up and, at predetermined numbers of turns, forms two commands K1 and K2 at the output. This number of turns is established on the counting device using switches 117 and 118 (Fig. 10). Team K1 (Fig. 4). At this command, the electric motor winding year cleverly moves to a lower speed. The number of turns of the winding coil, after winding which it is necessary to reduce the speed, depends on many factors (winding speed, tension of a multicore flat wire, etc.) and

5 experimentally using switch 117 (FIG. 10). The numerical value of the K2 command (Fig. 4) is set using the switch 118 (Fig. 10) and is equal to the number of turns of the winding coil. Minus 1. This command comes simultaneously

0 to the inputs of three control circuits of the shadow (Fig. 4); brake pneumatic cylinder, insulation stripping motor, electromagnets of isolation stripping mechanisms.

The signal from sensor 95 is supplied simultaneously to the inputs of the pneumatic cylinder brake control circuit and the engine sweep control circuit. The signals at the output of these circuits appear when two signals are simultaneously present at their inputs — K2

(the last but one turn) and the signal of the sensor 95, which appears when the cutout in the disk 85 (Fig. 10) coincides with the sensor 95.

Thus, after winding the penultimate turn, the electric motor 45 (Fig. 6) of the insulation stripping unit turns on and begins to rotate the corrugated rollers 53, which are still removed from the stranded flat wire 43. At the same time, the spool that controls

which retracts the levers 51 together with the grooved rollers 53 from the stranded flat wire 43. The length of the stripped portion on the stranded flat wire is determined by the length of the notch between the disks 87 and 88 (Fig. 12), which is adjusted by rotating these disks relative to each other and fixing them on the sleeve 91. The moment of the supply corrugated disk 53 (off electromagnets 58)

brake pneumatic cylinder 105 (Fig. 13), H is adjusted by turning sleeve 91 (Fig. 12) which moves to the right and presses together with disks 87 and 88 on the pinch bar 102, compressing the spring 103. This is row 4 (Fig. 10) with such.m.

The resulting braking torque helps to extinguish the inertia of the core of the electric motor 2 of the winding head 3 (Fig. 3). During the further course of the pneumatic cylinder 105 (Fig. 13), the scraper 102 presses the adjusting screw 106 and turns the locking lever 107 so that the roller 109 lies on the cylindrical surface of the fixing disk 98 (Fig. 10). The spindle 4 at the same time continues to rotate at a reduced speed, winding the last turn of the coil.

The signal from sensor 96 (FIG. 4) is fed to the input of the electromagnet control circuit of the stripping mechanisms. The signal at the output of this circuit disappears when two signals are simultaneously present at its input - K2 (the penultimate turn) and signal from sensor 96. Thus, when spindle 4 makes its last turn, then if the cutouts in the disks 87 and 88 coincide (FIG. 12) with the sensor 96, the electromagnets 58 are switched off simultaneously (FIG. 6).

would be located exactly under the upper electrodes 17 (Fig. 5) of the welding unit. After adjustment, the sleeve 91 (FIG. 12) is fixed by a screw 92.

Thus, the stripping of the section of the stranded flat wire from the insulation occurs when the spindle 4 (Fig. 5) winds the last turn of the roller 5. Since the brake pneumatic cylinder was previously turned on and the spindle 4 rotates

25 at a reduced speed, when rotated, the cutout in the fixing disk 98 (FIG. 10) fits the roller 109 (FIG. 13) of the locking lever 107, which is turned by the brake pneumatic cylinder 105 through the rod 102 so that the roller 109 sinks into

30 groove of the locking disc 98 (FIG. 10). The lever 107 (Fig. 13) at the same time presses the microswitch 110, which gives the command to turn off the winding motor and the electric motor 45 of the insulation stripper (Fig. 6).

In this case, under the action of the springs 62, the levers 51. At this time, the winding is completed, and the i-turn is rotated on the axles 50 and the supply 4 is fixed in the initial position of the wound rollers 53 to the stranded projection (Fig. 16).

water 43, which at this time is moving. After winding on the coil 5, set them up, winding it on the coil 5 (Fig. 1) at a low speed. As the rollers Q 53 (Fig. 6) also rotate, the stranded flat wire 43 is stripped of insulation. At this moment, the distance between the generators of the corrugated rollers 53 is approximately equal to the thickness of the conductive

lived wires 43. Adjustment on this thickness 45 cutting. In this case, the pneumatic cylinder 72 rotates by rotating the eccentrics 60, in (Fig. 5) it moves to the left, turning

which rest the levers 51 when the electromagnets 58 are turned off with their adjusting screws 59. The non-parallelness of the corrugated rollers 53 is adjusted by turning the screws 59.

As soon as the cuts in the discs 87 and 88 (Fig. 12) come out of the sensor 96, the second plate 112c is inserted with the leads (exactly the same as the first one welded at the beginning of the winding). The welding unit is turned on and a second strip is welded with leads to the multicore flat wire 43 (Fig. 16). After welding, the strip 112 is fixed to the coil 5. The assembly is turned on.

spindle 4 (fig. 10), the signal from this sensor at the input of the stripping electromagnet control circuit (fig. 4) disappears, and at the output of this circuit, a signal appears that includes both electromagnets 58 (fig. 6) of the stripping mechanisms . Electromagnets 58 attract measles 57,

body 6 of the cutting unit on the axis 65 counterclockwise and supplying it to the wound roller 5 (Fig. 17). The rotation of the housing 66 (FIG. 5) takes place until it rests against the protrusion 119 in the frame 14. With further movement of the rod of the pneumatic cylinder 72, the housing 66 remains in place and the toothed sector 69 rotates, moving the movable knife 68 upwards. At the same time, he departs from the two shoulders of the pawl 70, which, under the action of the spring 73, rotates on its axis and with its opposite shoulder goes behind the projection in the support 75. The toothed sector 69 continues at this time

which retracts the levers 51 together with the grooved rollers 53 from the stranded flat wire 43. The length of the stripped portion on the stranded flat wire is determined by the length of the notch between the disks 87 and 88 (Fig. 12), which is adjusted by rotating these disks relative to each other and fixing them on the sleeve 91. The moment of the supply corrugated disk 53 (off electromagnets 58)

 adjustable by turning sleeve 91 (FIG. 12) along with discs 87 and 88 on the pin 0

would be located exactly under the upper electrodes 17 (Fig. 5) of the welding unit. After adjustment, the sleeve 91 (FIG. 12) is fixed by a screw 92.

Thus, the stripping of the section of the stranded flat wire from the insulation occurs when the spindle 4 (Fig. 5) winds the last turn of the roller 5. Since the brake pneumatic cylinder was previously turned on and the spindle 4 rotates

5 at a reduced speed, as it rotates, the cutout in the fixing disk 98 (FIG. 10) fits under the roller 109 (FIG. 13) of the locking lever 107, which is turned by the brake pneumatic cylinder 105 through the rod 102 so that the roller 109 sinks into

0 the groove of the fixing disk 98 (FIG. 10). The lever 107 (Fig. 13) at the same time presses the microswitch 110, which gives the command to turn off the electric motor of the winding head (Fig. 1) and the electric motor. After winding to the coil 5, the cutting is set. In this case, the pneumatic cylinder 72 (Fig. 5) moves to the left, turning

The second plank 112c is connected with leads (exactly the same as the first one, welded at the beginning of the winding). The welding unit is turned on and a second strip is welded with leads to the multicore flat wire 43 (Fig. 16). After welding, the strip 112 is fixed to the coil 5. The assembly is turned on.

cutting In this case, the pneumatic cylinder 72 (Fig. 5) moves to the left, turning

body 6 of the cutting unit on the axis 65 counterclockwise and supplying it to the wound roller 5 (Fig. 17). The rotation of the housing 66 (FIG. 5) takes place until it rests against the protrusion 119 in the frame 14. With further movement of the rod of the pneumatic cylinder 72, the housing 66 remains in place and the toothed sector 69 rotates, moving the movable knife 68 upwards. At the same time, he departs from the two shoulders of the pawl 70, which, under the action of the spring 73, rotates on its axis and with its opposite shoulder goes behind the projection in the support 75. The gear sector 69 continues at this time

move the movable knife 68 up to the stationary knife 67, where the stranded flat wire section from the wound coil occurs. When the pneumatic cylinder 72 is switched to the reverse stroke of the two-armed dog, the dog 70 rests on the support 75 and does not allow the body 66 to return to its original position. Therefore, during the return stroke, the toothed sector 69 first rotates and moves the movable knife 68 down, which in the lowest position presses the screw 74 installed in the two shoulders of the dog 70, causing it to turn on its axis and come out of the engagement with the stop 75. After this, the body 66 The cutting assembly is able to turn on the ESI 65 to its original position, without hitting the lower electrodes 19 of the welding assembly.

The position of the wire stripped from the insulation after the stop has been stopped is adjusted so that the cutting line М-М (Fig. 18) passes just in the middle of its length. Therefore, after the cut, the free end of the stranded flat wire is stripped of insulation and prepared for welding the rail 112 for the next coil to it.
