Abstract

The utility model discloses an adjustable inner supporting die for the press fitting of a transformer coil. The adjustable inner supporting die comprises bidirectional screws and two die wall plates, wherein the two die wall plates are both provided with corresponding thread bushings; and the bidirectional screws are installed on the thread bushings on the two die wall plates by locking nuts. According to the adjustable inner supporting die for the press fitting of the transformer coil, regulation and change can be carried out by cooperating with the bidirectional screws in the minor axis direction of the coil in a two half-die mode, the adjustable inner supporting die can be suitable for supporting in the press fitting process of the coils of various sizes, and the coil press fitting size is guaranteed. The adjustable inner supporting die for the press fitting of the coil has the advantages of wide applicability, simple structure, easiness in manufacture and convenience in operation, and various problems brought by the situation of one die for one shape of the traditional inner supporting die are solved.

Description

A kind of adjustable transformer coil press mounting inner support mould

Technical field

The utility model relates to transformer Long Circle coil short-axis direction, the inner support mould when press-fiting, this inner support mould, have adjustable function, can use in the internal mold coil press mounting operation of certain adjusting range, have and adjust simply, size is accurate, the characteristics that a mould is multiplex.

Background technology

Constantly technological innovation, energy saving and cost lowering, increasing transformer adopting, oval unshakable in one's determination, the Long Circle winding construction, such design can be saved and be used material, reduced volume, but this Long Circle coil exists, the deficiency of shape one mould, coil needs a large amount of many specifications inner support moulds in press-fiting process, and press-fiting of this Long Circle coil focuses on, and the size of short-axis direction press-fits and controls, if adopt shape one method of module can form very large workload, mould overstocks, the modeling difficulty.

The utility model content

Utility model purpose: for press-fiting of Long Circle transformer coil, the utility model provides a kind of adjustable transformer coil press mounting inner support mould, it is a kind of in Long Circle coil short-axis direction assurance size, and carry out the mould of inner support, and this mould adopts the two-half die mode, and the inner reverse-flighted screw that coordinates is adjusted, and is applicable to the coil of plurality of specifications, and coordinate lock nut to guarantee press mounting dimension, be not subjected to displacement in handling process again.

Technical scheme: a kind of adjustable transformer coil press mounting inner support mould comprises reverse-flighted screw and two die wall plates; Be equipped with corresponding thread bush on described two die wall plates; Described reverse-flighted screw is arranged on two thread bushs on the die wall plate by lock nut.

Described each die wall plate is provided with the thread bush of four protrusions, and described reverse-flighted screw correspondence also has four, and the two ends of reverse-flighted screw are arranged in thread bush by lock nut, regulates two distances between the die wall plate by rotating reverse-flighted screw.

Beneficial effect: compared with prior art, adjustable transformer coil press mounting inner support mould provided by the utility model, utilize two-half die form (i.e. two die wall plates), coordinate reverse-flighted screw to adjust variation at the short-axis direction of coil, go for the support in process of press-fiting of sizes coil, guaranteed the coil press mounting size, this adjustable coil press mounting inner support mould, applicability is wide, simple in structure, make easily, easy to operate, solved the variety of problems that traditional support internal mould one shape one mould brings.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the structural representation of die wall plate in the utility model embodiment;

Fig. 3 is the use view of the utility model embodiment.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

As Figure 1-3, be equipped with corresponding thread bush 2 on two die wall plates 1: each die wall plate 1 is provided with the thread bush 2 that two rows protrude, and every row has two thread bushs 2 side by side.The two ends up and down of two die wall plates 1 all bend inwards, and comply with the bending radian of coil 5.

Four reverse-flighted screws 4 are installed in parallel on two thread bushs 2 on die wall plate 1 by lock nut 3; The two ends of each reverse-flighted screw 4 thread bush 2 on a corresponding die wall plate 1 respectively wherein, reverse-flighted screw 4 ends are arranged in thread bush 2 by lock nut 3 levels.

In use, adjustable transformer coil press mounting inner support mould, effect is short-axis direction support coils 5 inside from coil 5, guarantee when coil 5 outsides press-fit, inside dimension inconvenience, with convenient follow-up general assembly, when the minor axis dimension of different coils 5 not simultaneously, can regulate two distances between die wall plate 1 by adjusting reverse-flighted screw 4, and satisfy different sizes, after size is determined, tighten lock nut 3, with the assurance size constancy, thereby play the effect of support coils 5 inside.

The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.

Claims
