Embodiment Construction
[0005] refer to Figure 1-3 , The specific embodiment adopts the following technical scheme: it is composed of a steel plate 1, an adjustable length sleeve 2, a rectangular insulating tube 3 and a cardboard 4. The steel plate 1 is provided with a notch 11, the bushing 2 is provided with a socket 21, the steel plate 1 and the bushing 2 are connected through the notch 11 and the socket 22; the middle of the bushing 2 is a threaded rod 22, so that The length of the shaft sleeve 2 is adjustable. After the low-voltage coil is wound, the steel plate 1 of the present invention is leaned against the cardboard 4 on the inner wall of the insulating cylinder 3, and the two opposite steel plates 1 are pushed up with the bushing 2, and the threaded rod 22 of the bushing 2 is adjusted to make It supports the insulating cylinder 3 with a certain force, and then press-fits according to requirements, thereby ensuring the outer diameter of the low-voltage coil, preventing deformation of the in...

The invention provides an amorphous alloy low-voltage coil press mounting mould for a transformer, and relates a low-voltage of the transformer, in particular to a press mounting mould for a rectangular coil. The press mounting mould consists of a steel plate (1), a length adjustable shaft sleeve (2), a rectangular insulating cylinder (3) and a thick paper board (4), wherein the steel plate (1) is provided with a notch (11); the shaft sleeve (2) is provided with a faucet (21); the steel plate (1) and the shaft sleeve (2) are connected through the notch (11) and the faucet (21); and the middle of the shaft sleeve (2) is provided with a threaded rod (22) which makes the length of the shaft sleeve (2) adjustable. The amorphous alloy low-voltage coil press mounting mould is subjected to press mounting according to the requirements so as to ensure the outside diameter size of the low-voltage coil, prevent the insulating cylinder and the coil form deforming, and guarantee the performances of the transformer.
Description
Technical field: [0001] The invention relates to a low-voltage coil of a transformer, in particular to a pressing die for a rectangular coil. Background technique: [0002] Due to the limited thickness of the low-voltage insulating cylinder of the amorphous alloy transformer, the formed coil is easily deformed under the action of press-fit stress, and the performance of the transformer cannot be guaranteed. Invention content: [0003] The purpose of the present invention is to provide an amorphous alloy low-voltage coil press-fit mold for transformers, which can ensure that the insulating cylinder and coil are not easily deformed under the action of press-fit stress, and guarantee the performance of the transformer. In order to solve the existing problems of the background technology, the present invention adopts the following technical scheme: it is composed of a steel plate 1, an adjustable length sleeve 2, a rectangular insulating tube 3 and a thick cardboard 4, and the...
