Description

Technical Field

[0001] The utility model belongs to the technical field of transformer production, in particular to a wire winding and pressing device for high-frequency transformer production. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "a wire winding and clamping mechanism for high-frequency transformer production", and its application number is "CN202122373797.8". This patent can mainly extrude the coil wound by the high-frequency transformer to avoid the copper wire being too thick and causing a loose fit with the winding shaft frame, so that the coil winding conforms to the drawing size, reducing the labor workload of the staff, and after the coil is fixed by the fixing mechanism, the staff can adjust the position of the squeezing mechanism to cooperate with the compression of transformer coils of different sizes, thereby increasing the scope of use of the device.

[0003] However, in the process of extruding the coil wound by the high-frequency transformer, if the extrusion force is too large, some coils may be overstressed, resulting in deformation or damage. If the extrusion force is insufficient, it is difficult to achieve the purpose of densely stacking the coils. Therefore, the extrusion force is difficult to control, and it is difficult to make the force distribution of the coils uneven during the entire extrusion process, resulting in difficulty in ensuring the quality of the coils and affecting the performance of the transformer.
