The fixing plate and the preset block have universality and can be suitable for voltage coils of various types. The block that presets that has the second recess adopts the surplus epoxy casting in the runner to form, has practiced thrift the material, presets the block setting at the fixed plate and pours between the mould, has played the effect of stabilizing the coil, avoids rocking because of coil in the transportation, causes a secondary insulation distance to change to cause breakdown, make the product scrap. The product does not have the outstanding ware body of screw, need not to cut, polish, repair the bottom, has beautified operational environment, has practiced thrift operating time, has improved work efficiency, has promoted mutual-inductor bottom appearance quality simultaneously.
Description
The technical field is as follows:
the utility model relates to a fixed knot of voltage coil in casting mold constructs.
Background art:
the existing coil hoisting is to use a fixing piece combined by a fixing piece and a screw, each fixing piece is fastened on an iron core by two fixing pieces and a tightening belt. During die filling, screws which are bound on 4 fixing plates extending out of the coil are placed in the technical holes of the die, and the two ends of the die are fixed by nuts, so that the coil can be stabilized. The method has the defects that after demoulding, the screw which exceeds the position of the transformer body needs to be cut off, then the screw is polished to be about 5mm shorter than the bottom of a casting body, 4 holes are filled and leveled by epoxy mixture, when the screw is cut and polished, sparks splash and dust are generated, the field environment is influenced, the production and manufacturing time is prolonged, the appearance of the bottom of a product cannot be guaranteed, and the mutual inductor can generate partial discharge when the operation is not in place.
The invention content is as follows:
the utility model relates to a solve the problem that above-mentioned prior art exists and provide a fixed knot of voltage coil in casting mold constructs.
The utility model discloses the technical scheme who adopts has:
a fixing structure of a voltage coil in a casting mold comprises a fixing plate, a preset block, a casting mold, a plastic steel packing belt, the voltage coil and a screw, wherein the fixing plate is horizontally arranged in the casting mold, the preset block is arranged between the fixing plate and the inner wall surface of the casting mold, the screw penetrates through the casting mold and is in threaded connection with the fixing plate, and the voltage coil is hung on the fixing plate through the plastic steel packing belt.
Furthermore, four corners of the fixed plate are respectively provided with an installation ear, four screws penetrate through the pouring die and are correspondingly in threaded connection with each installation ear, and the left side edge and the right side edge of the fixed plate are respectively provided with a first groove for limiting the plastic steel packing belt.
Furthermore, a connecting nut is welded on the upper end face of each mounting lug, and the screw is in threaded connection with the connecting nut.
Furthermore, a second groove used for limiting the plastic steel packing belt is formed in the bottom surface of the preset block.
The utility model discloses following beneficial effect has:
the fixing plate and the preset block have universality and can be suitable for voltage coils of various types. The preset block with the second groove is formed by pouring residual epoxy in the pouring gate, materials are saved, the preset block is arranged between the fixing plate and the pouring die, the effect of stabilizing the coil is achieved, the phenomenon that the coil is shaken in the transfer process to cause secondary insulation distance change is avoided, and therefore primary breakdown is caused, and products are scrapped. The product does not have the outstanding ware body of screw, need not to cut, polish, repair the bottom, has beautified operational environment, has practiced thrift operating time, has improved work efficiency, has promoted mutual-inductor bottom appearance quality simultaneously.
Description of the drawings:
fig. 1 is a structural diagram of the present invention.
Fig. 2 is an assembly view among the fixing plate, the preset block and the plastic steel packing belt.
Fig. 3 is a structural view of the fixing plate.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As fig. 1 to fig. 3, the utility model relates to a fixed knot of voltage coil in casting die constructs, including fixed plate 1, preset a 2, pour mould 3, plastic steel packing area 4, voltage coil 5 and screw 6, fixed plate 1 level sets up in pouring mould 3, preset a 2 setting at fixed plate 1 and pour between the internal face of mould 3, screw 6 pass pour mould 3 and with fixed plate 1 threaded connection, screw 6, fixed plate 1 will preset a 2 conflicts on pouring the internal face of mould 3, voltage coil 5 through plastic steel packing area 4 hoist and mount on fixed plate 1.
Four corners of the fixing plate 1 are respectively provided with an installation lug 10, the upper end face of each installation lug 10 is welded with a connecting nut 13, and four screws 6 penetrate through the pouring die 3 and are correspondingly in threaded connection with the connecting nuts 13.
The left side and the right side of the fixing plate 1 are respectively provided with a first groove 11, and the bottom surface of the preset block 2 is provided with a second groove 22. After the fixing plate 1 is assembled with the preset block 2, the first groove 11 is communicated with the second groove 22. After the plastic steel packing belt 4 is bound, the plastic steel packing belt 4 is arranged in the first groove 11 and the second groove 22, and the grooves limit the plastic steel packing belt. The preset block 2 is formed by pouring residual epoxy in a pouring gate, so that the material is saved.
The voltage coil is placed on the iron core, and the inner side edge of the fixing plate is aligned with the inner side of the primary winding, so that the correct position of the fixing plate can be ensured.
The fixing plate is fastened on the voltage coil by the plastic steel packing belt, the position of the fixing plate is not movable, the joint of the plastic steel packing belt is placed in the first groove 11, and the joint of the plastic steel packing belt (the double-layer packing belt is thick and easily causes coil misalignment) can be perfectly decorated.
And (3) coil die filling, aligning a screw hole of a nut on the fixing plate 1 with a process hole of a casting die, screwing a screw 6 of M6 x 40 into about 5 wires, inserting the preset block 2 between the casting die and the fixing plate, clamping a second groove of the plastic steel packing belt on the plastic steel packing belt, screwing the screw, and finishing die filling after the pouring layer is adjusted.
Demolding: and (4) disassembling the bolts of the pouring die, disassembling the bottom plate of the die, and directly carrying out secondary curing and assembling without any treatment.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
