Abstract
The invention discloses a winding mold for a low-voltage winding of a dry-type transformer. The mold comprises a first half-mold, a second half-mold and a demolding block, wherein the first half-mold and the second half-mold are bent into an arc form through steel plates; the first half-mold and the second half-mold are connected with each other end to end to form a whole winding mold; a notch is formed in the spliced part; a first connection block is arranged at the inner side of the first half-mold; a second connection block is arranged at the inner side of the second half-mold; the first connection block and the second connection block are fixed by the demolding block through bolts; a through hole is formed in the middle of the demolding block; a resisting block blocked in the notch is arranged at the edge of the demolding block; and the resisting block and the demolding block are integrally molded. The mold has the advantages that after the low-voltage winding is wound, a gap is formed by the two half-molds by loosening the demolding block, and the upper half-mold and the lower half-mold are close to each other, so that the mold can be rapidly separated.
Description
Technical field
The present invention relates to a kind of dry-type transformer low pressure winding coiling mould.
Background technology
The low pressure winding of dry-type transformer is distributed in high pressure winding, in order to ensure that low-voltage coil is identical with the gap of high-tension coil, need to make the contour shape of low-voltage coil consistent with the contour shape of high-tension coil, but low-voltage coil is wound on iron core, its diameter is less than high-tension coil, present coiling low-voltage coil needs again to make winding mould and carries out coiling, owing to needing the low-voltage coil producing Multiple Type in process of production, in order to reduce the cost of more mold exchange, in the production technology of current dry-type transformer, most producers use timber and lamination is wooden makes mould, utilize the toughness of wood surface itself and plasticity to make interim winding mould, because wooden winding mould precision when coiling is poor, and anti-fight is poor, easily damage when the demoulding, cause the inconvenience of the demoulding.
Summary of the invention
The invention is intended to provide a kind of mould being convenient to the dry-type transformer low pressure winding coiling demoulding.
Dry-type transformer low pressure winding coiling mould in this programme, comprise the first half module, second half module and demoulding block, described first half module and the second half module are arc by steel plate bending, first half module and the second half module arc opening side fasten and can form complete winding former, and leave notch at fastening place, the first contiguous block is installed with inside first half module, the second contiguous block is installed with inside second half module, first contiguous block and the second contiguous block are fixed by bolt by described demoulding block, through hole is provided with in the middle part of described demoulding block, described demoulding block edge be provided be stuck in notch support block, described support block and demoulding block one-body molded.
The mold use principle of this low pressure winding coiling is: before coiling, first half module and the second half module are combined to form complete mold, to be stuck in notch to block, first contiguous block and the second contiguous block are fixed by bolt by demoulding block, the first contiguous block is installed with inside first half module, the second contiguous block is installed with inside second half module, after two pieces of contiguous blocks are fixing, namely the fixing of two pieces of half modules is completed, the roll of coil winding machine is penetrated in the through hole of demoulding block, whole mould is rotated along with coil winding machine, by the drive of coil winding machine, low-voltage coil carries out coiling at the outer surface of mould.
When the demoulding, unclamp the bolt on demoulding block and contiguous block, and the block that supports on demoulding block is exited notch, when after block exits notch, the demoulding identical with supporting block width can be reserved between first half module and the second half module stitch, take out the first half module and the second half module in the low pressure winding that now just can directly complete from coiling, the two-half die taken off can be reused next time.
The advantage of this programme is: by fixing demoulding block between two half modules, and is stuck in the notch between two half modules by the block that supports of demoulding block; After low pressure winding technique completes, make two half modules form spaces by unclamping demoulding block, upper and lower two half modules are close to each other, and half module outer wall and low-voltage coil are thrown off, and take out half module in the low-voltage coil directly completed from coiling, half module is reused.
Further, the binding post due to high-tension coil is one section of straight line, and in order to the contour shape of the low pressure winding making coiling shaping is identical with high-tension coil, the flexure plane of described first half module is provided with one section of plane.
Further, the inwall of the plane of described first half module and the flexure plane of the second half module is provided with reinforcement angle steel, although steel plate has good anti-bending strength, but the flexure plane of the plane place of the first half module and the second half module main stress surface that to be low-voltage coil shaping, by angle steel, this two place being carried out reinforcement can effectively support low-voltage coil.
Finally, the width of described notch is 10 ~ 30mm, can ensure the first half module and the second half module when dismantling demoulding block like this because notch is too wide to cave in, also can not cannot the demoulding because notch is too narrow.
Accompanying drawing explanation
Fig. 1 is the structural representation of dry-type transformer low pressure winding coiling mould of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: the first half module 1, second half module 2, demoulding block 3, notch 4, first contiguous block 51, second contiguous block 52, reinforcement angle steel 6.
Dry-type transformer low pressure winding coiling mould as shown in Figure 1, comprise the first half module 1, second half module 2 and demoulding block 3, first half module 1 and the second half module 2 are by steel plate bending camber plate, first half module 1 and the second half module 2 opening side fasten and can form complete winding former, and the notch 4 of 20mm is left at spelling fastening place, the first contiguous block 51 is installed with inside first half module 1, the second contiguous block 52 is installed with inside second half module 2, first contiguous block 51 and the second contiguous block 52 are fixed by bolt by described demoulding block 3, through hole 31 is provided with in the middle part of demoulding block 3, demoulding block 3 edge be provided be stuck in notch 4 support block 32, one-body molded to block 32 and demoulding block 3.
