DEVICE FOR WINDING WIRES ON CLOSED

It was filed on June 6, 1957, No. 574722 to the Committee for Inventions and Open

The main author. St. No. 112237 of April 29, 1957 on that person’s name

BASIC Auth. St. No. 112237, the device for winding the wire on closed ring cores is stitched. driven by compressed air in a closed path.

The proposed device is a further development of the device according to the author. St. Law 112237 and differs from it by changing the design of the bed in which it moves. shpuf - Takse device allows you to prevent arbitrary turning of the spool and increases the reliability of the winding.

FIG. 1 shows the frame of the proposed device; in fig. 2 and 3-two of its transverse section; in fig. 4 is a diagram of a variant of the device with an additional disk.

In the proposed device, the cavity / in the bed 2, in which the bobbin 3 moves, has an oval cross-section, which makes it possible to increase the length of the bobbin to the required dimensions. In front of the toroid, the oval cavity passes into a straight line section 4. In the upper and lower parts of part J, grooves 5 are arranged (Fig 2), into which protrusions in the spool enter. The grooves do not allow the bobbin to unwind during its entire course, and only when the spool is in diametrically opposite position from the winding core, does it get to rotate around its axis, as it falls into the bed section that has no grooves (Fig. 3) . Here, it winds off the necessary number of turns of wire to be wound on the core.

To provide the necessary tension and uniform wire laying on the core, the device can be equipped with a disk 6 fixed on the vertical axis (Fig. 4) with curved pins 7.

The pins 7 are evenly spaced around the circumference of the disk, as a result of which the wire 8 is unwound with a stitch, captures one of the pins and carries it along with it, causing the vrash to drive 6, Thus, the pin transports the wire as it were

Research Institute down to the core. At the moment when the pin discharges the 11 () gadfly, the W113N1 is in the diameter from the core direction. At this point, the next pin is approaching, which performs the same operation as the previous one.

The rotation of the disk 6 is used to rotate the winding core 9 using the corresponding kinematic transmission links 10.

The force on the disk is sufficient to set in motion the entire kinematic chain, since already at an air pressure of 6 atm a force of 250-300 g acts on the spool. The number of turns can be measured using a ratchet mechanism (not shown). The core is brought under the base 2 by means of the device //.

Subject invention

Claims (2)

1. Device for winding wires on closed ring cores according to the ed. St. No. 112237, characterized in that, in order to prevent arbitrary bobbing of the spool and increase winding reliability, the cavity in the frame is made with straight linear sections near the radial section and with an oval cross section, as well as with guide grooves throughout, plot diametrically opposite to the specified radial section, which interact with the corresponding protrusions of the spool. 2. The device according to claim 1, characterized in that, in order to provide the necessary tension of the wire and evenly place it on the core, o is provided with a disk fixed on a vertical axis with curved sleeves uniformly located on its circumference and alternately at each turn the spools are captured by the wire unwound from it, and the rotation of the disk caused by it is used with the help of the corresponding kinematic links for the step-by-step supply of the wound core.
