Popularize knowledge about the working principle of low-frequency transformer winding machine
The working principle of the winding mechanism of low frequency transformer winding machine, ring winding machine, automatic winding machine, and automatic winding machine is basically the same as that of other series winding machines. Worm gear 2 is basically driven by winding motor m2, due to cam 3 and The worm wheel 2 is coaxially connected, so they also rotate together to make the short feather key slide in the keyway. The sliding direction depends on the rotation position of the cam. When the cam rotates relative to the short sliding contact surface, if it rotates from a small radius to a large radius, Then the short sliding rod 5 slides, otherwise the short sliding cam slides, and the sliding interval is equal to the difference between the maximum radius and the minimum radius of the cam.
The short slide swings with the rod 5 as the fulcrum, the long slide 7 slides in the keyway, the traverse bracket 9 moves, the cam is rotated once, the short slide slides back and forth once, the rod tooth swings once, and the long slide slides back and forth once to make the cable The bridge frame reciprocates in the transverse direction, and the reciprocating distance of the spool depends on the position of the fulcrum of the control rod 5.
When the fulcrum is located in the middle of the short slider 4 and the long slider 7, that is, when the arm of the long slider is equal to the arm of the short slider, the movement interval of the wire frame is equal to the sliding interval of the short slider. 5mm after subtracting 25mm from 30mm.
In order to change the width of the winding, the low-frequency transformer winding machine only needs to turn the screw 6 to adjust the position of the fulcrum of the tie rod 5. When the line width is greater than 5mm, the fulcrum position of the control rod 5 can be moved to the short sliding direction. When the cable width is less than 5mm, Need to move the fulcrum to the long sliding direction.
When the low-frequency transformer winding machine needs to wind coils of different wire diameters, you only need to adjust the potentiometer of the constant voltage power supply to change the speed of the winding motor, and then you can change the speed of the shallow discharge motor or the speed of the cam 3. Drive changes the number of reciprocating motions of the spool, but the linear speed remains the same. Therefore, each time the spool moves, the number of turns will change. In other words, in order to meet the requirements of winding methods with different wire diameters, change the spacing per unit of the spool The number of windings.
Low-frequency transformer winding machine For example, the diameter of the coil is 0.2mm and the width of the coil is 5mm. At this time, adjust the speed of the winding motor M1 and the winding motor m2 to make the winding machine turn 50 times, that is, each layer rotates 25 times. Assuming that the width of the coil remains unchanged and the wire diameter becomes smaller, the stabilized power supply K6 needs to be adjusted to reduce the speed of the winding motor and the moving speed of the coil bobbin, and increase the number of coils wound on each layer to meet the requirements of reducing the wire diameter. On the contrary, if the wire diameter becomes larger, you only need to increase the speed of the winding motor to speed up the movement of the spool and reduce the number of turns per layer.
