Abstract
The utility model discloses a through can closely laminating together between the copper line layer that enables sharp panel in copper line and plane and plane straight line panel department and oval coil mould of small -size distribution transformer that can reduce intensity of labour, improvement work efficiency. Oval coil mould of small -size distribution transformer, including plane straight line panel, establish arc panel board, the baffle at both ends about the straight line panel of plane, both ends are connected with the baffle about plane straight line panel and arc panel board, division have the bar hole or the bar groove of intersecting with the baffle on the sharp panel in plane. The centre at plane straight line panel is opened in bar hole or bar groove. The utility model discloses have the copper line and hug closely technological effect with the copper line layer of plane straight line panel, plane straight line panel department, can also reduce intensity of labour, improve production efficiency together.
Description
Technical field
The utility model relates to mould, particularly the oval coil die of a kind of small distribution transformer.
Background technology
The small-sized folded iron core distribution transformer coils of current below 10KV mainly adopts the more round coil of Long Circle coil to have saving core material, reduces the advantage of no-load loss, but also there is mass of coil problem difficult up to standard, especially shows that coil minor axis dimension is overproof.Loop shaping is just cured the symptoms, not the disease, and both wastes material, wastes man-hour again, also directly affects life-span and the performance of transformer.It is linearity that described Long Circle coil refers in the middle of coil, and two ends are arc shape.As shown in Figure 1, be plane and straight line panel 4 in the middle part of the oval coil die of small distribution transformer of use, being located at plane and straight line panel about 4 two ends is curved panel 5; As shown in Figure 2, the left and right end of plane and straight line panel 4 and curved panel 5 is connected with baffle plate 1; By the cooperation being located at the bolts and nuts on baffle plate 1, plane and straight line panel 4, curved panel 5, baffle plate 1 are linked together.Because copper cash is in winding process, coiling can arch up to plane and straight line panel place copper cash, well can not be close between plane and straight line panel or copper wire layer and can not be close together, copper cash just can be made to be close between plane and straight line panel and copper wire layer after needs strike with a hammer to be close together, but, the effect be close to is not very desirable, beat also very require great effort, time-consuming.Learn in practice, plane and straight line panel is longer, and the phenomenon that arches up during coiling is more serious, beats and more requires great effort, and coil minor axis dimension is overproof.Copper cash is unbalance stress in winding process, and the larger impact of thickness is larger, faster around speed, and coil minor axis dimension is overproof also larger.
Summary of the invention
The technical problem that the utility model solves be to provide a kind of by together with making can to fit tightly between the copper wire layer of copper cash and plane and straight line panel and plane and straight line panel place and the oval coil die of small distribution transformer that can reduce labour intensity, increase work efficiency.
The technical solution of the utility model is, the oval coil die of small distribution transformer, include plane and straight line panel, be located at curved panel, the baffle plate at the upper and lower two ends of plane and straight line panel, plane and straight line panel is connected with baffle plate with the two ends, left and right of curved panel, and plane and straight line panel has the bar hole crossing with baffle plate or bar-shaped trough.
Further preferred embodiment, described bar hole or bar-shaped trough vertical with baffle plate.
Further preferred embodiment, described bar hole or bar-shaped trough open the centre at plane and straight line panel.
Further preferred embodiment, described baffle plate has bar hole or the corresponding groove of bar-shaped trough.
Further preferred embodiment, the width of described groove is greater than the width of bar hole or bar-shaped trough.
When using the utility model coiling copper cash, strike with a hammer the copper cash arched upward at bar hole or bar-shaped trough place, copper cash and plane and straight line panel can be made easily to be close together, also the copper wire layer at plane and straight line panel place can be made to be close together, reduce labour intensity, improve production efficiency, the overproof reduction of coil minor axis dimension can also be made.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is the right view of Fig. 1.
Embodiment
Be described in further detail the utility model by reference to the accompanying drawings, as shown in Figure 3, the oval coil die of small distribution transformer includes plane and straight line panel 4, is connected to the curved panel 5 at plane and straight line panel about 4 two ends, baffle plate 1; As shown in Figure 4, plane and straight line panel 4 is connected with baffle plate 1 with the two ends, left and right of curved panel 5; Plane and straight line panel 4 has the bar hole vertical with baffle plate or bar-shaped trough 3.By the cooperation being located at the bolts and nuts on baffle plate 1, plane and straight line panel 4, curved panel 5, baffle plate 1 are linked together.After coil plane straight line panel 4, curved panel 5 have been wound around, bolt, nut are unloaded, baffle plate 1 is separated with plane and straight line panel 4, curved panel 5, then will be located at coil inner plane straight line panel 4, curved panel 5 released.
For conveniently copper cash can be beaten, copper cash and plane and straight line panel 4 are close together or the copper wire layer that is located at plane and straight line panel 4 is close together, baffle plate 1 has bar hole or the corresponding groove 2 of bar-shaped trough 3.
For conveniently beaing copper cash, copper cash and plane and straight line panel 4 are close together or the copper wire layer that is located at flat panel is close together, the width of described groove 2 is greater than the width of bar hole or bar-shaped trough 3.
The above is only preferred embodiment of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, also should be considered as protection range of the present utility model.
