Abstract
This utility model relates to an ellipse loop axle voltage press-loading conformation for flame-proof mine transformer, which comprises an upper mould and a lower mould of the ellipse loop axle press-loading respectively melding with a beam channel and a stiffener. A loop is equipped on the lower mould of the ellipse loop axle press-loading, while the upper mould of the ellipse loop axle press-loading is equipped on the loop. The upper mould and the lower mould of the ellipse loop axle press-loading are pressed closely with screws. This utility model has the advantages that it properly adds ellipse loops and moulds to ensure smooth upper and lower surfaces after press-loading of the ellipse loop so that the moulds are provided with certain intensity and good bearing without deformation after long-term press-loading of the moulds. A plurality of press-loading points enable convenient operation, good versatility, and thereby being suitable for axle press-loading operation of the ellipse loops and satisfying the needs of the press-loading capacity.
Description
Technical field
What the utility model related to is a kind of axial press mounting structure of oval coil that is used on the flame proof mining transformer.Belong to the transformer technology field.
Background technology
At present, the high-voltage coil and low-voltage coil structure of flame proof mining transformer is circular and square two kinds, must carry out shaping after coil winding finishes and promptly carry out axially press-fiting of coil, makes the axial height of coil meet the drawing requirement.The high-voltage coil and low-voltage coil press mounting structure of existing flame proof mining transformer is easy cross structure (the circular coil press mounting structure also can be used circular press mounting structure).The shortcoming of easy cross structure be load a little less than, mould is yielding to press-fit a little less the rear surface out-of-flatness of large-scale coil press mounting.Circular press mounting structure shortcoming is for press-fiting complicated operation, and Mold Making requirement height and mould can not be general, and the coil of each capacity just must be used a kind of mould.Existing cross press mounting structure and circular press mounting die, also incompatible oval coil axially press-fits operation.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence.Propose a kind of take a kind of practicality axial press mounting die, increased oval coil and mould contact surface in right amount, guaranteed that oval coil press-fits the planarization that lower plane is gone up in the back, mould has certain intensity, to satisfy the needs of pressure assembling force, mould does not produce metaboly through after press-fiting for a long time.
Technical solution of the present utility model: its structure be oval coil axially press-fit upper and lower mould respectively with channel-section steel, the stiffener welding constitutes, coil axially press-fits on the bed die at oval coil, oval coil axially press-fits mold on coil, and oval coil axially press-fits upper and lower mould and by screw rod coil compressed.
Advantage of the present utility model: increased oval coil and mould contact surface in right amount, guaranteed that oval coil press-fits the planarization that lower plane is gone up in the back, mould has certain intensity, and load is strong, and mould does not produce metaboly through after press-fiting for a long time.Press-fit a little manyly, easy and simple to handle, versatility is good, and what adapt to oval coil axially press-fits operation, satisfies the needs of pressure assembling force,
Description of drawings
Accompanying drawing 1 is that the axial press mounting structure of oval coil is always schemed.
Accompanying drawing 2 is the axial press mounting die front elevations of oval coil.
Among the figure 1 is that oval coil axially press-fits mold, the 2nd, and oval coil axially press-fits bed die, the 3rd, screw rod, the 4th, coil, the 5th, channel-section steel, the 6th, stiffener.
Embodiment
The contrast accompanying drawing, its structure be oval coil axially press-fit upper and lower mould 1,2 respectively with channel-section steel 5, stiffener 6 welding constitute, coil 4 axially press-fits on the bed die 2 at oval coil, oval coil axially press-fits mold 1 on coil 4, and oval coil axially press-fits upper and lower mould 1,2 and by screw rod 3 coil 4 compressed.
Claims (1)
1, the axial press mounting structure of oval coil, it is characterized in that oval coil axially press-fits upper and lower mould (1,2) and constitutes with channel-section steel (5), stiffener (6) welding respectively, coil (4) axially press-fits on the bed die (2) at oval coil, oval coil axially press-fits mold (1) on coil (4), and oval coil axially press-fits upper and lower mould (1,2) and by screw rod (3) coil (4) compressed.
