Abstract
The invention relates to a low-voltage foil winding adjustable die of a dry type transformer. The low-voltage foil winding adjustable die comprises a mandrel and is characterized in that one end of the mandrel is connected with a screw rod; an end sliding disk is installed on the screw rod; the left, right, upper and lower parts of the mandrel are movably connected with four symmetrical panels respectively by support rods; one sides of one ends of the panels towards the mandrel are connected with foundation support strips; the foundation support strips are arranged in sliding grooves on the outer surface of the end sliding disk; and the panels can be driven by the foundation support strips to do radial motion along the mandrel. The outside surfaces of the panels are circular arc surfaces, and ear holes are arranged on the inside surfaces of the panels; corresponding ear holes are respectively arranged on the upper, lower, left and right surfaces of the mandrel; both ends of each support rod are respectively connected with the ear holes on the mandrel and panels by pins; and the surface of the outside end of the end sliding disk is provided with a tooth groove and a circular hole. The low-voltage foil winding adjustable die of the dry type transformer has a simple, compact and reasonable structure; and by manually adjusting the end sliding disk to pull the support rods, the purpose of changing the diameter of the circular arc panels in the radial direction can be achieved.
Description
Technical field
But the present invention relates to a kind of mode transfer, but the low blocking of especially a kind of dry-type transformer belongs to electrical equipment technical field around mode transfer.
Background technology
Transformer inside can be divided into coil and two large divisions unshakable in one's determination, and mostly employed winding former was wooden solid mould in the coiling process in the past, and it is to make according to the size of coil diameter.And the transformer of different capabilities and manufacturer production, its coil diameter and highly having nothing in common with each other.Must make the winding former of different size during coiling.And wooden winding former is made, processing technology is complicated, and fabrication cycle is longer, and easy deformation, damage, can not use for a long time.Cause the significant wastage of material, and influenced the production cycle, also strengthened the stacking area in place simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art; But provide the low blocking of a kind of dry-type transformer simple in structure, compact, rational around mode transfer, make the circular arc panel flexible diametrically to reach the purpose of reducing through manual adjustments end sliding plate pulling support bar.
According to technical scheme provided by the invention, but the low blocking of a kind of dry-type transformer comprises mandrel around mode transfer, and characteristic is: an end of said mandrel is connected with screw mandrel, and the end sliding plate is installed on screw mandrel; About said mandrel, flexibly connect the panel of four symmetries respectively through support bar up and down; One end of said panel is connected with basic stay towards a side of mandrel; Said basic stay is arranged in the chute of end sliding plate outer surface, and said panel can drive the radial motion along mandrel by basic stay.
The outer surface of said panel is an arc surface; Inner surface is provided with earhole; About the said mandrel, about be respectively arranged with corresponding earhole on four faces, the two ends of said support bar respectively be arranged on mandrel and be connected through pin with earhole on the panel.
The surface of said end sliding plate outboard end is provided with teeth groove and circular hole.
The end of sliding plate is provided with dismountable gear stop in said end, and said gear stop is made up of with the gear that is connected with shaft with key way the shaft with key way of an end; Teeth groove engagement on said gear and the end sliding plate.
Said mandrel is square mandrel.
On the outer arc face of the panel of said mandrel top a plane is set, on said plane, is provided with groove, L shaped gag is set in groove.
The present invention is simple in structure, compact, reasonable; Make the circular arc panel flexible diametrically through manual adjustments end sliding plate pulling support bar to reach the purpose of reducing.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
Like Fig. 1～shown in Figure 3: but the low blocking of dry-type transformer comprises gag 1, gear stop 2, basic stay 3, mandrel 4, panel 5, pin 6, support bar 7, earhole 8, end sliding plate 9, screw mandrel 10, circular hole 11, shaft with key way 12, gear 13 etc. around mode transfer.
The present invention includes square mandrel 4, an end of said mandrel 4 is connected with screw mandrel 10, and end sliding plate 9 is installed on screw mandrel 10, and the surface of said end sliding plate 9 outboard end is provided with teeth groove and circular hole 11; At said mandrel about 4, connect four panels 5 through support bar 7 symmetries respectively up and down; The outer surface of said panel 5 is an arc surface; Inner surface is provided with three earholes 8; About the said mandrel 4, about be respectively arranged with corresponding earhole 8 on four faces, the two ends of said support bar 7 respectively be arranged on mandrel 4 and be connected through pin 6 with earhole 8 on the panel 5; One end of said panel 5 is connected with basic stay 3 towards a side of mandrel 4; Said basic stay 3 is arranged in the chute of end sliding plate 9 outer surfaces; Said basic stay 3 can be along runner movement, promptly panel 5 can be in the guiding lower edge of basic stay 3 radial motion of mandrel 4;
The end of sliding plate 9 is provided with dismountable gear stop 2 in said end, and said gear stop 2 is made up of with the gear 13 that is connected with shaft with key way 12 shaft with key way 12 of an end; The effect of the adjustable mode diameter of locking end sliding plate 9 rotational fixation is played in teeth groove engagement on said gear 13 and the end sliding plate 9;
On the outer arc face of the panel 5 of said mandrel 4 tops a plane is set, on said plane, is provided with groove, L shaped gag 1 is set in groove, so that adapt to the copper bar of different size.
The course of work of the present invention: but when regulating the diameter of mode transfer; Pull up gear stop 2; Crow bar is inserted rotation end sliding plate 9 in the circular hole 11 of end sliding plate 9; End sliding plate 9 promotes basic stay 3 makes circular arc panel 5 pulling support bars 7 flexible diametrically to reach reducing, and the teeth groove that insertion gear stop 2 is bitten on the end sliding plate 9 when mould diameter reaches desired value end sliding plate 9 can not be rotated again plays the effect that locks sliding plate 9 stationary adjustable mode diameters; In addition; Paper tinsel around the time torsional forces that produces mainly bear by support bar 7; Mandrel 4 mainly bears the weight of assemblies such as radial component and coil, circular arc panel 5, end sliding plate 9; Thereby improved the anti-torsion ability of winding former greatly, produced the dimensional accuracy that distortion has guaranteed coil effectively when having reduced coiling.
