Description

The invention relates to the technological equipment of dp and fabrication of pentochny magnetic circuits and can be used in the electrical, electronic, instrument-making industries of the industry. A device for manufacturing twisted ribbon (x magnetic cores containing a drive, a spindle, a mandrel feeding mechanism, a cutting mechanism and a tape feed, a pressing mechanism, a tailstock 1 is known. The closest technical solution to the proposed is a device containing a mandrel feeding mechanism, a cutting mechanism and tape feed, runway, spindle, pressing mechanism and tailstock with a cheek 2j. A disadvantage of the known devices is that they need to have a device for removing the filling end of the tape, besides This reduces the quality of the magnetic conductors, especially when winding small sizes., The purpose of the invention is to simplify the process of manufacturing products. The goal is achieved by the device containing the mandrel feeding mechanism, cutting mechanism and iodine pentam, drive, spindle , the pressing mechanism and the tailstock with the cheek, containing the bracket mounted on the pinopi of the tailstock, the mechanism for clamping the end of the tape to the mandrel, made in the form of a spring-loaded swivel single-arm lever with height Mentioned, mounted on the cheek of the tailstock, and three disks mounted on the bracket with the possibility of reciprocating movement along the axis of the rear & b, the middle disk is made with a groove and mounted with the possibility of rotation, and the protrusion of the lever has the ability to contact the groove of the middle disk. FIG. 1 shows the device, general view; in fig. 2 is a view A of FIG. one; in fig. 3 - Section BB in FIG. 2; in fig. 4 a, b, 2 - cutting scheme and strapping the end of the tape to the mandrel. The device for manufacturing twisted tape magnetic cores (Fig. 1) consists of a cutting mechanism 1 and a tape feed, a mandrel feeding mechanism 2, a spindle 3, a drive 4, a tailstock 5 of the pressing mechanism 6. On the tailstock 5, there is a clamping mechanism for the end of the tape to the mandrel (Fig. 2.3), which consists of a clamping lever 7, which can be rotated under the action of a torsion spring 8 on the axis 9, attached to the cheek 10 of the tailstock. A bracket 11 is fixed on the quills of aadya granny 5, on which a pneumatic cylinder of ± 2 is attached to a double-arm lever 13, swinging on axis 14. In guides of bracket 11, disks 15-19, coherently connected with columns 20 and having the possibility of translational movement under the action of springs 21 compression. Inside the discs 15 and 17 there is an installation disk 16 having a groove B. In the grooves of the disks 16 and 17 there is a tension spring 22, which serves for; returning the disk 16 to its original position. In the disk 15 there is a key 23, which serves to fix the disk 16 in its original position. The device for manufacturing twisted ribbon magnetic cores works as follows. The feeder, the mandrels 2 feeds the mandrel without the shaped groove in the winding zone. The back of headstock 5 pushes the mandrel into the window of the cheek spindle 3. In this case, the tape, after preliminary cutting, is fed by the pusher under the mandrel (Fig. 4). The movable knife and the fixed knife are installed so that the end of the tape is not bent 90 after cutting. The lever 7 presses the end of the tape to the mandrel. The pusher mechanism for cutting and feeding the tape moves back. The roller of the pressing mechanism 6 approaches the mandrel and the spindle 3 is turned on. 4b, the lever 7 is retracted into the groove of the cheek 10 (FIG. 2) and the magnetic circuit is further formed. The mechanism of the clamp end of the penta to the mandrel, mounted on the tailstock 5, works as follows. When air is supplied to the cavity of the pneumatic cylinder 12, the force of the rod is transmitted to a double-arm lever 13, which, having overcome the resistance of the springs 21, presses to the disk 19,: is tightly connected by the columns 20c by the disks 15-18. the torsion spring 8 rests on the disk 16 on the nth j i4ara 7 .. The lever 7, turning on the axis 9, comes out of the groove of the cheek 1O and presses the awning against the mandrel. With

rotating the spindle 3 p of the lever 7, slipping over the mounted disk 16, sinks into the groove B (Fig. 3) of the disk 16 under the action of the torsion spring 8. Pepacho rynaga 7 releases the tyunta and goes into the 5th groove of the cheek 1O. At the same time, a command is given to raise the stem of the pneumatic piston 12, and consequently, the disk 16 retracts under the action of springs 21. During the time from the commencement of the command to raise the rod Yuka before the end of the movement of the disks 15-18 to the right, the setting disk 16 rotates 774

Under the action of the heel of the lever 7, overcoming the resistance of the spring 22. When the heel of the lever 7 leaves the groove, the installation disk 16 returns to its original position until it stops at the key 23 by the spring 22.

The use of the proposed device will allow eliminating the operation for removing the filling end of the tape, increasing the productivity and quality of small sizes of magnetic circuits.
