SU744752A1 - Machine for winding toroidal cores - Google Patents

Description

The invention relates to technological equipment for the manufacture of electric coils and can be used in the radio electrical engineering and instrument-making industry. A known machine for winding toroidal cores, containing mechanisms for holding and turning the core, a leash worn on two pulleys and passing through one branch in the center of the core, a resetting device for separating the coil and adjustable brake 1. However, the known machine does not provide a large supply of wire easy dumping of turns of a wire. The aim of the invention is to increase the supply of the coiled wire with the separation of the coils of the stock from each other and to facilitate the discharge of the turns of the wire from the sh: yv to form a stock. The goal is achieved by the fact that the machine contains two kinematically connected swivel rollers, each of which has rods fixed in the form of spring spokes, carrying a wire margin and pulleys entering the end cavities, while the rollers are connected with an adjustable brake and the leash is fitted with a guide spring flag. FIG. 1 schematically shows the proposed machine, FIG. 2, the node T in FIG. i; in fig. 3 a, b, c - node 2 in FIG. one; in fig. 4 - winding scheme with one turn of the wire stock. The machine contains a base 1, in which the drive and controls are installed (not shown in the drawing). The pulley 2 is connected with the pulley 3 by an endless detachable driver 4 with a spring-loaded flag 5. The swivel rollers 6 and 7 are kinematically connected by a cross-belt 8, allowing the rollers to rotate in opposite directions. The rollers 6 and 7 comprise protrusions 9, made in the form of spring spokes with freely rotating nozzles, which enter the grooves of the plates 10, 11 and overlap the gap S. Coils of wire are placed in the gap to prevent the formation of loops. The core 12 is installed in the mechanism 13 of the holder and the rotation of the core.

The machine operates as follows. The toroidal core is inserted into the mechanism of the holder and the core rotation, the leash is passed through it, and the lock is closed. The coiled wire 14 is at one end passed through the spring flag | And is fixed on the leash, which is driven by one of the pulleys. The lead wire is pulled through the core, and the spring flag is pressed against the lead. After reaching the core, the flag 5c rises above the driver and drops the wire from the pulley 3 into the gap S. In this case the wire is held up by one of the projections 9 of the roller 7, Next the wire is held up by one of the projections 9 of the roller 6, and the flag 5, again passing first turn, creating a coil of wire stock. The following turns of the wire margin are superimposed on the corresponding protrusions 9 of the rollers b and 7, similarly when the rollers are turned. After stocking, the other end of the wire is attached to the core.

The lead wire is pulled tight, and the turn rolls B and 7 begin to turn until the turn comes off the protrusions 9.

After tightening the coil on the core, the swivel rollers begin to turn again, and the cycle repeats until the drive stops after winding the number of turns of the winding.

During winding the core 12 turns around its axis

lot of mechanism 13 holding and turning the core ..

Tension of the wire during tightening of the turn. The wires on the core are provided by braking the swivel rollers with an adjustable brake.

The proposed machine, in comparison with the known, allows to increase the margin of the wire and to facilitate the discharge of the loop of wire from the pulleys to form a margin.
