In the development of switching transformers, a small transformer winding machine can not be bought, so with wood, 8# iron wire, 3 long screws and 3 nuts and 3, 5 gaskets, etc., to build a simple and simple small winding machine and wire roller frame, wound several small ferrite transformers, excellent effect.

1, winding machine construction method and steps

The author used the waste materials used to decorate the home wood floor to build a wood frame with a length, width and height of 13139cm. In order to knot, drill 8 holes (each under each side) with about 3 drill bits and fix them with 4 wood screws. When built, attention is paid to detail, accuracy and reliability. After the frame is made, punch a 3.6mm ~ 4mm hole for each corresponding end face, the hole is centered on the left and right, and the upper and lower parts are selected as 2cm, so as to install the winding crank later. The frame can also be replaced by similar ready-made wooden boxes, iron boxes, etc., and the geometric size is also suitable for the material, as long as it is suitable.

2 Build the crank as much as possible with hacksaw (joint end flat) cut 8# wire to make the shape of the crank. Then file both ends flat (you can also use a grinding wheel or coarse sandpaper, or even on a concrete surface). On the ground of the two smooth roots, and then put the short end of the edge along the edge to prevent the hand from being cut when shaking the handle.

3 Assembly Before assembly, first prepare 5 gaskets 2, length 2.5cm3cm, diameter 3 long screws 1, 3 nuts 2, and A, B glue (also known as brother good), and then you can assemble. The assembly steps are as follows: thread the long end of the rocker through a hole in the constructed frame, thread a 5 gasket on the rocker head on the inside of the newly pierced frame, and then thread the rocker head into another hole in the frame. Next, when the long rod head of the rocker is exposed to 5cm in the hole, the gasket that is penetrated into the inside of the wood frame at the long rod head is placed on the inside of the wood frame, and the adjusted A and B glue is applied to the outside of the rocker and the gasket. Before the glue is quickly and completely solidified (10 minutes to 20 minutes), turn the rocker several times to avoid the glue exposed to the gasket hole sticking the wood frame and the gasket. Wait for half an hour after the glue is completely solidified, and then stick a 5 gasket in the same way at the exposed end of the long rod. When applying glue, the long rod is outward, so that the inner gasket is attached to the inside of the frame to prevent shaking when winding the coil. In short, the inner and outer sides of the gasket are properly tight, after the glue solidifies, so that the rotating shake will neither shake around, but also rotate. After that, use A and B glue to bond the head of the 3 screws with the long rod head. After bonding, try to make the two axes parallel, and pay special attention to correcting the parallelism of the two when the glue is about to set.

2, the construction of line roller frame

When winding the transformer, a enameled wire roller support frame is needed, and I made a simple and simple structure with 8# iron wire. Construction method: Take a piece of 8# iron wire about 1m, bend it side by side by hand into the shape as shown in Figure 3, and use pliers to shape the place that is not good. Leave about 5cm long at the curved interface, so that the wire contact is stacked, and then wrap it tightly with enameled wire. Then, trim properly so that it is placed smoothly. Then, find a big screwdriver or a hard plastic tube with a length of 15cm that can pass through the human line rolling hole, and place the line rolling with the line rolling frame so that the line rolling can smoothly rotate and pay off the line when winding. If there is a small wooden box or plastic foam box on hand, dig two small suitable slots at the midpoint of the two corresponding sides of the opening (the groove is slightly deeper than the line roll support bar), it can also be used as a line roll frame.

3. Winding of transformer

Winding transformer with a simple winding machine and a wire roller frame is basically similar to the regular product winding method, but it also has its particularity. The following is a brief introduction to the winding method. 1 Install and fix the transformer skeleton on the simple winding machine 3 screws first screw a 3 nut, screw depth depends on the transformer skeleton size, and then install the gasket (gasket size depends on the skeleton size), and then install the skeleton, and then put a gasket, and finally screw on a 3 nut fastening the skeleton. In order to facilitate the winding, try to fix the skeleton at the screw end. 2 Place the wire roller. Use a stiff straight rod of suitable length and thickness to thread the wire rolling hole and place it in the groove of the wire rolling frame prepared in advance. 3 Wind the transformer coil. Place the winding machine and the wire roller frame on the table about 20cm away from each other (the wire roller frame is close to the human body). In order to avoid the instability of the winding machine, several 32K books or other objects can be pressed on it. Secondly, it is necessary to clarify the pins of the skeleton corresponding to the same end and the same end of the winding coil, and then the coil can be wound. When winding the coil, the wire hand controls the enameled wire about 5 points toward the target of the wire layout. While not stacking the wires, ensure that the wire layout is careful and neat. Remember the number of turns when winding. When encountering a coil with a large number of turns, it is advisable to make a mark every 10 turns to prevent misremembering. The specific winding transformer method is not described here.
