Description

i 1

The invention relates to manufacturing equipment for the manufacture of inductors, in particular, devices intended for winding and tensioning, for example, inductor coils, and to be used in the manufacture of I1 reducers with winding insulation for induction furnaces.

The aim of the invention is to improve the performance of the capabilities.

FIG. J shows a proposed device, a general view; FIG. 2 shows section A-A in FIG. one.

The device contains a rotary table 1 with a drive 2. On the rotary table 1 there are fastened clips 3, the pins 4 of which are mounted in a fixed axis; S is rigidly bonded to the base. The clips 3 are mounted coaxially and in such a way that the code of the subsequent holder 3 is located inside the pre. On each holder 3 there are fixed crossheads 6, on which clamping mandrels 7 are installed. On crossbars 6 there are threaded bushings 8 into which adjusting bolts 9 are screwed. The gap between mandrels 7 is less than the thickness of the inductor coil wire. The upper mandrel 7 is fixed fixedly on the pivot bracket 10 by means of pins 11. The bracket 10 can be rotated around the post 12. On the rotary and upper fixed mandrels 7 in the corresponding holes .I3 the ends of the inductor coil wire are fixed 5 , bolted 14.

Us groystvo works as follows.

Before installing the indiz / coil coil, the bracket 10 is raised, the pins 11 are withdrawn from the holder 3 of the mandrel 7, after which the bracket 0 is retracted to the side, turning around the stand 12 o

The inductor coil is mounted on expanding mandrels 7. The ends of the inductor coil drive are fixed respectively on the lower and top mandrels 7, for example, by bolts 14. Then drive 2 and turn table I turn on with lower expanding coil 7 and the coil of the inductor coil fixed

rotate. Upper expansion mandrel 7 UAH this still. Part of the vit-rs located on the lower mandrel 7, at the same time, is tightened, and the gaps

g me: hell, expandable mandrel and coil are eliminated. Due to the frictional forces, which take place with the mlsdoured coil windings and the surface of the expanding mandrel 7, a sharp heel occurs, the second ment, which promotes the rotation of the second adjacent mandrel. In this case, the second mandrel 7, rotating relative to the stationary third adjacent mandrel, tightens the vit | ki coil.

After shrinking the coils on the second mandrel, the third mandrel engages in rotation, and then the fourth

20 w etc. ,

Thus, there is a consistent tightening of the turns on the mandrel from the bottom up to the last stationary. Selected gaps between the turns of the inductor and the mandrel contribute to the formation of wire loops, which are eliminated when one mandrel rotates relative to another. After the final

JQ pull coils of the inductor all mandrels are stopped due to the safety devices of the drive, for example, a friction clutch.

3 f o rm o l i

An apparatus for manufacturing inductor coils, comprising a base, a spring retainer mandrel for accommodating the coils, mounted on an axis and connected to a rotational drive, about three times so that, in order to improve operational performance, it is equipped with a bracket, mounted on the base, with the possibility of rotation, the axis of the mandrel is completed from the set of installed ones; coaxially clips, each;:; and of which has a pin located inside the subsequent clips rotatably,.

The bracket is made of individual parts, the cords of which are rigidly connected with the corresponding yoke, while the upper yoke is fixed on the bracket, and the spigot n: and above is installed on the B base.
