Abstract

The invention relates to the electrical industry, in particular to equipment for the manufacture of light sources, and is intended for supporting windings on the filament spirals of tubular incandescent lamps. The aim of the invention is to provide a winding of supports of a wire of larger diameter while saving wire. The coil with the core is inserted into the collet chuck 33, and the support winding wire is threaded into the feed mechanism. After switching on the motor, the wire feed mechanism pushes it between the protrusion of the mandrel 31 and the helix. As the spindle 29 rotates, the wire coils on a spiral. After winding a certain number of turns on the coil, the disk 30 and the spindle 29 stop. At this time, the spindle 29 together with the mandrel 31 moves to the right until the wire enters the grooves on the mandrel 31. The knife cuts off the wire and the pressure roller comes in contact with the mandrel 31. The disk 30 is released and the mandrel 31 begins to rotate. In this case, larger diameter wire rings are formed on it. Then the spindle 29 is stopped again, the collet chuck 33 is opened and the spiral feeding mechanism feeds it by the set pitch between the supports. Then the cycle repeats. The device allows winding supports from thicker and stiffer wires and save material due to the lack of technological ends. 5 il.

Description

variable 3KOHOhfflH wire. The coil with the core is inserted into the collet chuck 33, and the support winding wire is threaded into the feed mechanism. After switching on the motor, the wire feed mechanism pushes it between the protrusion of the mandrel 31 and the helix. When the hapindle 29 is rotated, the wire is wound on a spiral. After a certain number of turns are wound onto the coil, the disk 30 and the spindle 29 are stopped. At this time, the spindle 29. along with the mandrel 31 moves to the right until the wire enters the grooves on the mandrel 31. The knife cuts off the wire and the pressure roller comes in contact with the mandrel 31. 30 is released and the mandrel 31 begins to rotate. In this case, larger diameter wire rings are formed on it. Then, the hapindle 29 stops again, the collet chuck 33 opens and the spiral feeder feeds it to the set pitch between the supports. Then the cycle repeats. The device allows winding supports from thicker and stiffer wires and saves

The invention relates to the electrical industry, in particular to equipment for the manufacture of light sources, and is intended for winding supports on the helix, on the body of an alloy of tubular incandescent lamps.

The aim of the invention is the expansion of technological capabilities by providing coiling supports of larger wire diameter while saving wire.

Figure 1 shows the device, front view; in FIG. 2, the winding mechanism, section; in fig. 3 - feed mechanism for dies, front view; figure 4 - the feeder helix with core; Fig. 5 is a diagram of the interaction of elements of the device. The support coiling device has a table 1 (FIG. 1), on the plate of which the support winding mechanism 2, wire feed mechanism 3, pressure roller 4, spiral feed mechanism 5, spiral receiver 6, electric motor 7, belt transmission 8 and console 9 are mounted. management Under the slab of the table, levers 10-15 are mounted, controlled by fists 16-21j sitting on the camshaft 22 of the winding mechanism 2.

The support winding mechanism 2 (FIG. 2) consists of a housing 23 in which a shaft 24 is mounted, carrying a spring 25, a disc sleeve 26, a nu tester 27 transmitting the gear rotation .28 sitting on the spindle 29, the slot bears the locking disk 30 and the mandrel 31 with the gland nut 32.

Inside the spindle 29 are the collet chuck 33, the clamping ring 34 and the spring 35.

The wire feeder (Fig. 3) consists of a body 36 on which a guide 37 is mounted, bearing on axis 38 a dog 39 with a spring 40, a movable lever 41 with a roller 42, and guides 43-45 for the wire.

The coil feeding mechanism 5 with a core (Fig. 4) consists of a body 46, a movable guide 47, on which racks 48 and 49 are mounted, carrying rollers 50 and 51. There is a torsion spring 52 on one of the rollers, and at their ends rigid gears 53.54 and sponges 55.56 are seated to grip the helix.

In the diagram of the interaction of the elements of the device (Fig. 5), the coil 57 with the wire, the knife 58 for cutting the wire, the wire 59 and the coil 60 with the core are indicated.

The device works as follows.

The coil from the core is inserted into the collet clamp 33, and the wire 59 from the coil 57 passes through the guide 45 and passes through the pawl 39 into the guide 43. Pressing the Start button of the control 9 starts the electric motor 7, which transmits the rotation through the belt drive 8 2 winding. At this time, the lever 13 rotates the lever 41 by means of the fist 21 and through the roller 42 moves the guide 37 towards the front (left), and the dog 39 with its sharp edge captures the pro 5
