Abstract
The utility model discloses a forming mould for a straight line portion of an oval poured coil of a dry type transformer. The mould comprises a supporting plate, pressing bolts, a pressing plate and auxiliary clamping plates, wherein the auxiliary clamping plates are arranged at the upper end and the lower end of a coil pouring outer mould, the supporting plate is positioned on a pouring outer mould of the straight line portion, the upper end of the supporting plate penetrates the auxiliary clamping plate at the upper end of the coil pouring outer mould, the lower end of the supporting plate penetrates through the auxiliary clamping plate at the lower end of the coil pouring outer mould, and a group of pressing bolts penetrate through the supporting plate to tightly press pressing plates on the outer side of the straight line portion of a coil. By means of the mould, the straight line portion of a poured coil can completely meet requirements, and product quality is improved.
Description
Technical field
The utility model relates to a kind of transformer shaping dies, specifically the oval molded coil straight line portion of a kind of dry-type transformer shaping dies.
Background technology
Dry-Transformer Technology is continuous optimal design in industry development, for dry-type transformer iron core cross section and the coil of saving the production of the present dry-type transformer of cost manufacturer mostly is Long Circle.Casting mold need to be made corresponding change like this, but the casting mold external mold mostly is soft mode, before cast, is wrapped in the coil outside, and straight line portion can't be close to coil, causes pouring into a mould out the coil straight line portion with radian.Have a strong impact on the coil presentation quality, can not guarantee to assemble rear spaced apart.
Summary of the invention
In order to improve the casting quality of oval coil, the purpose of this utility model is to provide the oval molded coil straight line portion of a kind of dry-type transformer shaping dies, after adopting this mould, waters the coil straight line portion that outpours and meets the requirements fully, has improved product quality.
The purpose of this utility model is achieved through the following technical solutions:
The oval molded coil straight line portion of a kind of dry-type transformer shaping dies, it is characterized in that: this mould comprises supporting bracket, hold-down bolt, pressing plate and auxiliary clamping plate, described auxiliary clamping plate are arranged on the two ends up and down of coil cast external mold, supporting bracket is arranged on the cast external mold of coil straight line portion, and the auxiliary clamping plate of coil cast external mold upper end are passed in the upper end of supporting bracket, the auxiliary clamping plate of coil cast external mold lower end are passed in the lower end of supporting bracket; One group of hold-down bolt passes supporting bracket and pressing plate is pressed on to the outside of coil straight line portion.
In the utility model, at auxiliary clamping plate two ends, be provided with the bar hole suitable with the supporting bracket width, bar hole is all passed in the top and bottom of supporting bracket.One group of hold-down bolt evenly arranges along the supporting bracket length direction.The width of described pressing plate and coil straight line portion length are suitable.
After adopting the utility model, water the coil straight line portion that outpours without radian, be shaped, water the coil straight line portion that outpours and meet the requirements fully, greatly improved the quality of coil.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
the oval molded coil straight line portion of a kind of dry-type transformer shaping dies, as depicted in figs. 1 and 2, this mould comprises supporting bracket 1, hold-down bolt 2, pressing plate 3 and auxiliary clamping plate 4, auxiliary clamping plate are two, be arranged on respectively the two ends up and down of coil cast external mold 5, at auxiliary clamping plate two ends, be provided with the bar hole suitable with the supporting bracket width, supporting bracket is arranged on the cast external mold of coil straight line portion 6, and the auxiliary clamping plate of coil cast external mold upper end are passed in the upper end of supporting bracket, the auxiliary clamping plate of coil cast external mold lower end are passed in the lower end of supporting bracket, bar hole is all passed in the top and bottom of supporting bracket.One group of hold-down bolt evenly arranges along the supporting bracket length direction, and passes supporting bracket and pressing plate is pressed on to the outside of coil straight line portion 6.The width of pressing plate and coil straight line portion 6 length are suitable.
To assist up and down clamping plate to be installed on casting mold in use, supporting bracket is passed to auxiliary clamping plate, with hold-down bolt, pressing plate is pressed to again on the cast external mold of straight line portion of coil, make straight line portion not outstanding, assurance is watered the coil straight line portion that outpours without radian, be shaped, water the coil straight line portion that outpours and meet the requirements fully, greatly improved the quality of coil.
