Description

The invention relates to technological equipment for winding ring cores and can be used in the electrical industry.

A known machine for winding annular cores containing a spool installed in a bearing with an annular groove to accommodate a supply of wire and with a removable insert, in which a tension roller device is located f 1)

However, this machine does not provide winding ring cores with a large number of turns, since the volume of the spool for placing the wire is limited. This narrows the technological capabilities of the machine.

The purpose of the invention is the expansion of technological capabilities.

This goal is achieved by the fact that the bearing has an annular groove, which forms, together with the annular groove of the spool, a cavity for accommodating the supply of wire.

In FIG. 1 shows the machine, a general view; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section AA in FIG. 1 (option for attaching the spool in ¹ rolling bearings).

RING

The machine contains a spool 1 with an annular 'cavity 2 for holding the supply of wire, installed in bearings 3 or 4. In the sliding bearings 3 or rolling 4, an annular groove is made, forming, together with the annular groove of the spool, a cavity for holding the supply of wire. , put the tension roller device 6. In the housing of the insert 5, additional holes 7 are made for changing the position of the rollers in order to regulate the tension of the wire. The spool is equipped with a ring gear 8. For fixing the end-wire 9, an eccentric clip 10 is used. For fixing and turning the core 11, a mechanism 12 is used.

Winding ring cores on the machine is as follows.

First, the spool insert 5 is removed l _{f the} core 11 is strengthened in the mechanism 12. The end of the wire 9, wound from the bobbin, is passed through the tension rollers 6 on the removed removable insert 5, then the insert 5 is mounted on the spool 1, the machine is turned on. The spool rotates using a ring gear 8, the wire 9 is wound into an annular cavity with a sufficiently small inner diameter and a large range of the number of turns.

and automatically cut off. The machine 'is stopped, the end of the wire 9, already threaded through the tension rollers 6, is clamped in the eccentric clamp 10. Turn on the machine and, after winding two turns on the core 11 (to fix the wire 9 on the core 11), press the handle of the eccentric clamp 10 to release the end of the' wire 9 (without stopping the machine), while the wire 9, mounted on the heart. " Nick 11, passing and bending on the rotating idler rollers 6, is pulled. The interference is adjusted when setting up the machine by rearranging the rollers 6 in the additional holes 7 provided for this purpose. The free placement of the wire 9 in the annular cavity 2 allows you to reel it unhindered from the lower layers of the stock.

Efficiency from using a machine of this design includes ensuring the winding of cores

(54) MACHINE FOR WRINKING RING CORES The invention relates to technological equipment for winding {core cores and can be used in the electrical industry. The known machine for winding ring cores, contains a spool with a ring pair installed in the tanker to accommodate a margin of wire and with a removable insert, in which a tension roller device 1 is located. However, this machine did not provide ring cores with a large number of turns, since the volume of the spool for locating the wire is fixed. This reduces the technological capabilities of the machine. The purpose of the invention is the expansion of technological capabilities. This goal is achieved by the fact that a ring groove is made in the hearth, which, together with the ring groove of the spool, makes a cavity for expanding the margin of wire. FIG. 1 shows a machine, a general view; FIG. 2 is a section A-A in FIG. 1} in FIG. 3 shows section A-A in FIG. 1 (option to mount the spool with rolling bearings). The machine contains a spool 1 with an annular cavity 2 to accommodate a margin of wire installed in bearings 3 or 4. An annular groove is formed in sliding bearings 3 or rolling 4, which together with the annular groove of the spool have a cavity for accommodating the margin of wire. In the removable insert 5 there are spools A roller device 6. In the case of the insert 5, additional holes 7 are made to change the position of the rollers in order to control the tension of the wire. The spool is equipped with a ring gear 8. To fix the end-of-wire 9, an eccentric clamp 1p is used. The mechanism 12 serves for fastening and turning the core 11. The winding of the ring cores on the machine is carried out as follows. Initially, the insert 5 is removed. The spool 1 core 11 is secured in the mechanism 12. The end of the wire 9, unwound from the reel, is passed through the tension rollers 6 on the removable removable insert 5, then the insert 5 is fixed on the spool 1, turn on the machine. The spool is rotated by means of the ring gear 8, the wire 9 is wound into the annular cavity 2 and is automatically cut off. The machine is stopped, the end of the wire 9, already threaded through the tension rollers 6, is clamped in the eccentric clamp 10. The machine is turned on and, after putting two coils on the core 11 (to fix the wire 9 on the core 11), press the handle of the eccentric clamp 10 to release the end of the wire 9 (without stopping the machine), while the wire 9, fixed on the core 11, passes and bends on the rotating tension rollers 6, and is pulled. The tension is adjusted when setting up the machine by swapping the rollers b in the additional holes 7 provided for this purpose. The free placement of the wire 9 in the annular cavity 2 allows it to be wound unhindered from the lower layers of the stock. The effectiveness of the use of the machine of this design implies the winding of cores with a sufficiently small inner diameter and a large range of turns. The invention The machine for winding ring cores containing a spool installed in a subplate with an annular groove to accommodate a margin of wire and with a removable insert in which a tensioning device is located, characterized in that, in order to expand technological capabilities, an annular groove is formed in the bearing, forming together with the annular groove of the spool cavity for wire margin.
