Abstract
The utility model relates to the manufacture of coils, in particular to winding formers and press fitting devices in the manufacture of transformer coils. The winding formers of the utility model is formed by that a sloping block 4, channel steel 6 provided with a slotted hole and an aluminum bar 1 fixed with a sloping block 3 are welded on the outside of a retaining ring; the channel steel with axial movement can adjust the diameter of a winding wire casing to realize the demoulding of coils. The coil press fitting device adopts a pressure plate whose center is not provided with a hole and whose surrounding is provided with long holes; the assembly and disassembly is convenient, and the universality is high; a linkage section and a spanner are additionally arranged between draw rods to cause the coil press fitting to have the advantages of labour saving and convenience.
Description
The utility model relates to winding former and the press-loading apparatus that manufacturing of a kind of coil, particularly transformer coil are manufactured.
The coiling of coil normally is ready to the winding former of suitable diameter earlier, again with lead on winding former.The kind of winding former has many, and wherein a kind of is that aluminum strip directly is fixed on the back-up ring, and the diameter of back-up ring is constant, and the diameter of winding former is immutable, and winding former is not general, and the coil that winds is difficult for separating demoulding difficulty with winding former.
The coil that winds needs the axial compression typing again, promptly needs to press-fit.Because winding former can not take off, the suitable trim ring of have to doing size is enclosed within on the mould exerts pressure to coil, and press mounting tool is not general.There is screw thread at trim ring pull bar two ends, produce pressure by screwing nut, and it is difficult producing big pressure.
For addressing these problems, but common way is to manufacture baroque diameter mode transfer and nut screws machinery, and originally back-up ring and aluminum strip all are done for, and equipment investment is very big.
The purpose of this utility model is to make full use of under the prerequisite of original equipment, improves winding former and press-loading apparatus, only needs less investment, finishes the coil demoulding and press-loading apparatus generalization and mechanization.
The purpose of this utility model is achieved in that and has added the channel-section steel that is welded with skewback between back-up ring and aluminum strip, fixing skewback on the aluminum strip, mobile beam channel vertically, change the relative position of two skewbacks, the gross thickness of two skewbacks is changed, to regulate the external diameter of winding former, winding former is separated with coil; With the pressing plate line ball circle of middle atresia, improve the versatility of pressing plate; The circumference of pressing plate has been opened long mouthful, and the pull bar mounting or dismounting are very easy; Load onto fastener by the connecting rod joint in the middle of the pull bar,, change the length of pull bar, reach the purpose that coil is provided thrust by the rotation fastener.
The utility model is because only need add channel-section steel and skewback between the back-up ring of winding former and aluminum strip, slot at the pressing plate circumference, on pull bar, add connecting rod joint and fastener, so simple in structure, original mould and device all can utilize, and realize the requirement of transforming old equipment with less investment easily.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 and Fig. 2 are the installation diagrams according to the winding former that the utility model proposes, and Fig. 3, Fig. 4, Fig. 5 are the installation diagrams according to the coil press mounting device that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1-Fig. 5 according to the concrete assembling die that the utility model proposes.
This assembling die comprises winding former and press-loading apparatus.Winding former contains back-up ring 2, and along channel-section steel 6 and aluminum strip 1 that circumference evenly assembles, press-loading apparatus has top board 12, and along the pull bar 13,17 that circumference evenly assembles, pull bar is linked together by connecting rod joint 15 and fastener 16.
Owing to fixed gradient on channel-section steel 6 and the aluminum strip 1 respectively and be 10-40 ° skewback 3,4, and have wide 8-17mm on the channel-section steel 6, the slotted hole 9 of long 20-100mm, aluminum strip 1 are fixed together with skewback 3 and bore shoulder hole 19, and slotted hole 9 is crouched identical with the center of shoulder hole 19 and in the length direction symmetry, so mobile beam channel 6 vertically, skewback 3,4 relative displacements have changed the diameter of winding former.Screw screw 5, lead is become coil 8 on winding former, because of channel-section steel 6 than aluminum strip 1 long 50-200mm, press arrow 7 mobile beam channel 6 vertically, skewback 3,4 relative displacements, the winding former diameter diminishes, and separates with coil 8.
Coil is placed on circumference has evenly opened wide 12-30mm, on long mouthful 18 the pressing plate 12 of long 20-200mm, after top board put, the connecting rod joint 15 of being opened the hole and being attacked the screw thread of m12-30 by the centre removed double hook with pull bar 13,17 with by the double hook wire grip, the fastener 16 that puts the screw thread of m12-30 connects together and puts into long mouthful 18 of pressing plate 12, packing ring 11 is put at two ends, screws on nut 10, rotation fastener 16, pull bar is shortened, coil is exerted pressure.
