Abstract

The invention relates to electrical engineering, radio engineering and instrumentation and can be used in the manufacture of twisted tape magnetic circuits. The purpose of the invention is to increase the manufacturing productivity and improve the quality of the magnetic cores by increasing their solidity. Essence: the welding head mechanism is provided with a carriage with a drive of its reciprocating movement with an adjustable stroke, carrying a parallelogram mechanism, while the welding machine torch is mounted on a parallelogram mechanism, and the carriage drive is electrically connected with the spindle fixation mechanism switches. 2 Il.

Description

This moves 10 to the screws 14, after which the mechanism of the welding head is fed to the mandrel with the magnetic wound and the internal coil is welded at one point. Then the carriage 8 is raised to the screw 15, the mechanism of the welding head is fed again to the mandrel with a magnet

the wire and welding of the internal coil at another point. At the end of the winding, the spindle is fixed and a “welding of the outer coil at several points, similarly, occurs, which makes the magnetic conduit solid, 3 sludge.

The invention relates to manufacturing equipment for the manufacture of these tape magnetic circuits, can be used in electrical, radio, instrument, compost4S industry and is an improvement of the invention according to the author. No. 1347104.

The purpose of the invention is to increase the productivity of manufacturing and improve the quality of the magnetic cores by increasing their solidity.

FIG. 1 shows the device, a general VIEW} in FIG. 2 shows the welding head mechanism in FIG. 3 - schemes of welding of the inner (from) and outer (b) turns.

The device for manufacturing the twisted ribbon magnetic cores (Fig. 1) consists of a cutting mechanism 1 and feeding the lectures, a pressing mechanism 2, a welding head mechanism 3, a mechanism 5 for removing the mandrel 5, a drive 6 and a spindle 7.

The welding head mechanism (Fig. 2) d is equipped with a carriage 8, on which a parallelogram mechanism 9 is mounted, carrying a torch 10. The carriage 8 has the ability to move up and down columns 11 using an actuator in the air input of a pneumatic cylinder 12 connected to a pneumatic distributor, which is electrically connected with spindle locking mechanism switches. Columns 11 are fixed on the bracket 13 mounted on the base plate of the device. On the bracket 13 there are screws 14 for adjusting the stroke, which are stops when the carriage 8 is moved down. The screw 15, which is fixed on the carriage B, is the stop when it moves upwards.

The device works as follows.

In the initial position, the spindle 7 (Fig. 1) is fixed by a spindle locking mechanism. The belt 16 (Fig. 3) is fed into the winding zone and fixed on the mandrel 5. The shaft of the spindle 7 is fixed and begins to rotate. After the first revolution of the spindle 7, the fixation mechanism switch issues signals to the pneumatic distributors for fixing the spindle 7 and moving the carriage 8 up and down.

The spindle 7 is fixed. Air enters the cavity of the pneumatic cylinder 12 and the carriage 8 with the parallelogram device 9 fixed on it and the burner 10 moves in columns 11 to the stops 14 fixed on the bracket 13. When the burner reaches the stops 14, a signal is outputted to the pneumatic distributor of the welding head 3. Air enters the cavity of the pneumatic cylinder 17 and the mechanism 3 of the welding head is supplied to the mandrel 5 (Fig. 3a). There is a welding of the internal coil at one point. Then, the welding head mechanism 3 returns to its original position. The carriage 8 rises to the position adjusted by the screw 15. A signal is again given to the pneumatic valve of the welding head mechanism 3 which is supplied to the mandrel 5, and the internal coil is welded at another point (Fig. 3a). After welding the internal coil, the mechanism -3 of the welding head returns to its original position, the spindle 7 is broken, and the magnetic core is further formed. At the end of the winding of the magnetic circuit, the size control is triggered, the tape is cut and the spindle locking mechanism switch supplies a signal to the pneumatic distributors for fixing the spindle 7 and the mechanism 3 of the welding head.

The spindle 7 is fixed. Air enters the cavity of the pneumatic cylinder 17 and the mechanism 3 of the welding head is supplied to the workpiece of the magnetic circuit 18 (Fig. 36). There is a welding of the outer coil at one point. Then the mechanism 3 of the welding head returns to its original position, the signal to the pneumatic valve moves down and up the carriage 8 and the air enters the cavity of the pneumatic cylinder 12. The carriage 8 with the burner 10 moves down to the stops 14. The signal to the pneumatic valve the welding head, which is supplied to the preform 18 of the magnetic circuit, and the outer turn is welded at another point. Then, the welding head mechanism 3 returns to its original position, the carriage 8 rises until it stops, the removal mechanism 4 removes the workpiece 18. and the cycle repeats.

Depending on the technological process of manufacturing a magnetic circuit, some points of welding of the inner and outer turns can be omitted.

Welding of the inner and outer VITKOV-in the area of cutting the magnetic circuit at one point negatively affects the solidity of these and subsequent turns in this area of the magnetic circuit, and consequently, the quality of the magnetic circuits. After cutting the magnetic core, the remaining ends of the inner and outer turns

tend to (weakly attach them to the workpiece) to be removed (the effect of dissolution) on many magnetic pipelines during the course of subsequent operations, which leads to failure of the equipment and decrease in its performance.

The proposed device provides welding of the inner and outer coils at several points and any place of these coils, so welding no longer affects the solidity of the magnetic core in the cutting zone, the ends of the coils are firmly fixed on the magnetic conductor, which leads to improved product quality and productivity . | labor.
