Abstract
The utility model provides a hot pressing die for a magnetic pole coil, comprising a lower pressing ring, a spacing screw and a floating supporting column both fixed on the lower pressing ring, an upper pressing ring arranged on the lower pressing ring, and a left end module, an expanding block, and a right end module which are all arranged inside the lower pressing ring in order, wherein the middle of the left end module, the expanding block and the right end module is provided with a middle die core hole. The hot pressing die for a magnetic pole coil has the beneficial effects of avoiding height dimension out-of-tolerance after hot pressing, insulation damage, and turn-to-turn short circuit.
Description
Technical field
The utility model relates to water under high pressure turbine generator secondary process apparatus field, especially relates to a kind of pole coil hot-die.
Background technology
The high pressure pole coil is the heart of generator, and its quality of production quality directly affects the useful life of generator.My company employs new technology, the high pressure pole coil of new material design.In the processing of pole coil emphasis heat pressing process, always adopt the old technology of traditional hot pressing, be hot pressing when processing, need with the pole coil hot-die put in the pole coil internal diameter size, with briquetting with module compress, the heating that heats up then, in the effect pressed moulding of hydraulic press.Be prone to overproof serious, the height dimension of pole coil, height dimension after the compression moulding if go up poor, need to field-coil flange carry out reconditioning to meeting the design drawing size till, during the cover utmost point, be prone to produce creepage phenomenon, directly affect product insulation quality and quality attractive in appearance, undersized then might easy damaged turn-to-turn insulation cause turn-to-turn short circuit, need be from new compacting, waste a large amount of raw material, after die mould finishes, with the briquetting press pack modules, increased operator's labour intensity.
Summary of the invention
The purpose of the utility model provides and a kind ofly avoids that hot pressing compacting back height dimension is overproof, the damage insulation, cause the pole coil hot-die of turn-to-turn short circuit.
The technical scheme of the utility model is: the pole coil hot-die; Comprise lower clamping ring; Be fixed on spacing screw rod and unsteady pillar on the said lower clamping ring; Also comprise being placed on the last trim ring on the said lower clamping ring and being placed on left end module, the piece that rises, the right-hand member module in the said lower clamping ring successively, be middle core rod hole in the middle of said left end module, the piece that rises, the right-hand member module.
Further, said going up on the trim ring also is provided with pressure cap.
Further, the said trim ring both sides of going up are provided with handle, all are provided with suspension ring on said lower clamping ring, left end module, the piece that rises, the right-hand member module.
Advantage and the good effect that the utlity model has are: the present invention adopts new frock, development new technology parameter, has formulated the reasonable process processing method; Thereby realized pole coil hot pressing compacting new technology; The physical dimension that has guaranteed coil is height dimension especially; Guarantee the inherent insulation quality of pole coil, avoid Inter-turn Short Circuit Phenomenon, improved the inherence and the presentation quality of product, have the raw material of saving, alleviated operator's labour intensity.

Embodiment
Like Fig. 1, shown in Figure 2; The utility model comprises lower clamping ring 5; Be fixed on the spacing screw rod 1 on the said lower clamping ring 5 and be placed on the unsteady pillar 14 on the said lower clamping ring 5 through nut 2, packing ring 3; Also comprise being placed on the last trim ring 6 on the said lower clamping ring 5 and being placed on left end module 7, the piece 9 that rises, the right-hand member module 12 in the said lower clamping ring 5 successively, be middle core rod hole 10 in the middle of said left end module 7, the piece 9 that rises, the right-hand member module 12.
Further, said going up on the trim ring 6 also is provided with pressure cap 8.
Further, said trim ring 6 both sides of going up are provided with handle 13, all are provided with suspension ring 11 on said lower clamping ring 5, left end module 7, the piece 8 that rises, the right-hand member module 12.
The course of work of this instance:
1) at first with spacing screw rod 1 be installed in lower clamping ring 5 screwed holes, by design drawing adjustment and height dimension, use nut 2, packing ring 3 then, with it with lower clamping ring 5 fastening putting together on.
2) pole coil of at first putting pad well turn-to-turn insulation lifts in the lower clamping ring 5, is respectively charged into trim ring 6, left end module 7, the piece 9 that rises, right-hand member module 12, is placed on the hydraulic press platform, presses trim ring 6, pressure cap 8 everything is ready afterwards that hydraulic press begins to pressurize,
3) pole coil rose to about 60 ℃-70 ℃ from room temperature through 10-15 minute, and the operator will be placed on the module with lead big little module is compressed.
4) pole coil continued to be warming up to 85 ℃-95 ℃ through about 10-25 minute; The operator is earlier concordant with the pole coil adjustment that goes between up and down under this temperature; Install the pillar 14 that floats additional, then with it on design drawing authorized pressure pressed given size to spacing screw rod 1 and unsteady pillar 14 positions.
4) under the design drawing authorized pressure, survey the turn-to-turn withstand voltage test.
5) the qualified continued of turn-to-turn withstand voltage test heats up, and continues to be warming up to 175 ℃-195 ℃ through about 20-30 minute.
5) 175 ℃-195 ℃ insulations of temperature 60-80 minute.
7) after insulation finished, outage cooling immediately when temperature is reduced to 60 ℃ of-70 ℃ of left and right sides, was removed the pressure mould unloading, the field-turn insulation moulding.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
