Abstract
The utility model relates to a thin-plate die for a high-capacity epoxy resin poured dry-type transformer, and belongs to the technical field of rectifier transformers. The thin-plate die for the high-capacity epoxy resin poured dry-type transformer comprises an internal die, an external die, a press-mounting frame, and a lower-end plate. The utility model is characterized in that both the inner die and the external die adopt thin-plate dies; a pressure strip is arranged at the contra-aperture part of the internal die, a pressure strip is arranged at the joint part of the external die and a line-outgoing panel, and an air groove plate is mounted between the internal die and the external die. The utility model has the advantages of simple structure, portability, practicality, good selectivity and generality of fittings, fast and easy assembly and disassembly of dies, and low manufacturing cost.
Description
Technical field
The utility model belongs to the rectifier transformer technical field, particularly relates to a kind of big volume loop epoxy resins casting dry type transformer thin plate mould.
Background technology
At present, the big demand of volume loop epoxy resins casting dry type transformer in power equipment market is increasing.The rigid mould of known big volume loop epoxy resins casting dry type transformer is made of inner mold, outer mold, upper end cover and bottom end cover.Along with improving constantly of enterprise's resin casting dry-type transformer technological and manufacturing level and production capacity, the manufacturing of the incompatible big volume loop epoxy resins casting dry type transformer high-tension coil of traditional rigid casting mold of resin casting dry-type transformer coil, there is the requirement height to equipment in it, the manufacturing process-cycle is long, the expense height, take up an area of problems such as big, becoming influences the big bottleneck that each transformer manufacturing enterprise reduced cost, improved production capacity and benefit.
Summary of the invention
The utility model provides a kind of big volume loop epoxy resins casting dry type transformer thin plate mould for solving problems of the prior art.
The purpose of this utility model provides and a kind ofly simple in structurely, light is suitable for, alternative good, versatility is good, the form removal of group mould is quick easily, processing cost the is low big volume loop epoxy resins casting dry type transformer thin plate mould of accessory.
The technical scheme that the big volume loop epoxy resins of the utility model casting dry type transformer is taked with the thin plate mould is:
A kind of big volume loop epoxy resins casting dry type transformer thin plate mould, by inner mold, outer mold, press-fit frame and bottom plate constitutes, be characterized in: inner mold and outer mold are the thin plate mould, inner mold counterpart place is provided with press strip, outer mold and outlet panel junction are provided with press strip, and internal mold is equipped with the air drain plate with outer intermode.
The big volume loop epoxy resins of the utility model casting dry type transformer can also adopt following technical measures with the thin plate mould:
Described big volume loop epoxy resins casting dry type transformer thin plate mould is characterized in: the air drain plate is the several piece frame mode that is bolted together.
Described big volume loop epoxy resins casting dry type transformer thin plate mould is characterized in: press-fit frame and press-fit frame for the rice font.
Described big volume loop epoxy resins casting dry type transformer thin plate mould, be characterized in: outer mold and outlet panels outside are fixedly clamped together by clamp.
Described big volume loop epoxy resins casting dry type transformer thin plate mould, be characterized in: the outlet panel is provided with 4-30 wire hole.
Described big volume loop epoxy resins casting dry type transformer thin plate mould, be characterized in: the thickness of thin plate mould is 2-3mm.
Advantage that the utlity model has and good effect:
Big volume loop epoxy resins casting dry type transformer thin plate mould owing to adopted the utility model brand-new technology scheme, has therefore had following characteristics:
The thin plate mould reduces greatly contrasting the rigid mould of same specification in price, significantly reduced die manufacturing cost, and the structurally light suitable characteristics of thin skin mould, can no longer be subjected to the restriction of products with larger capacity mould heaviness, difficult carrying, improve the flexibility that product design and mould use greatly.
The thin plate Mould Machining is simple relatively, and the working ability of Mould Machining producer has been reduced requirement, and alternative the raising shortened the production cycle of transformer greatly, makes design, production time more abundant, more nimbly and freely.
Simultaneously the thin plate Mould design of products with larger capacity is more reasonable, and group mould, form removal are easier easily, with respect to the big rigid mould of weight the lifting of overhead traveling crane, with the fastening means of supply reel, the thin skin mould has all been done the structural adjustment of suitable hommization.Reduce the workshop working strength of workers, improve labor productivity.
The utility model carries out corresponding process modification and structural adjustment to the thin skin mould on products with larger capacity, apply in the coil cast of poured with epoxy resin dry-type transformer, will bring considerable comprehensive benefit.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of looking up of Fig. 1.
Among the figure, 1-outlet panel, the 2-press strip, the 3-press strip, the 4-external mold, the 5-internal mold, 6-press-fits frame, 7-air drain plate, 8-seals offset plate, 9-bottom plate, 10-suspension ring.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and be described with reference to the accompanying drawings as follows:
Embodiment
Big volume loop epoxy resins casting dry type transformer thin plate mould press-fits frame 6 and bottom plate 9 constitutes by inner mold, outer mold, upper end, and sealing offset plate 8 is housed on the bottom plate 9, and a meter font press-fits suspension ring 10 are housed on the frame 6.Internal mold 5 and external mold 4 are the thin plate mould, and the thickness of thin plate mould is 2mm.Inner mold counterpart place is provided with press strip 2, and external mold and outlet panel junction are provided with press strip 3, and outer mold and outlet panels outside are fixedly clamped together by clamp.Outlet panel 1 is provided with 23 wire holes.4 of internal mold 5 and external molds are equipped with air drain plate 7.Air drain plate 7 is 64 POM uses that are bolted together.
The specific design of present embodiment:
1. existing thin plate mould is the mold design of 10000kVA product.
2. the material of the inside and outside mould of high pressure mould and specification: select for use the 2mm cold-rolled steel sheet to make inside and outside mould, change gentle frid height according to the rerum natura of resin-cast process and select mold height.
3. adopt more firm press-fit approach: redesign press-fits suspension bracket, behind assembling outlet panel and external mold, utilizes it that mold integral is compressed, and prevents to occur leaking in the process of cast the situation of resin material.
4. the sealing offset plate between internal mold and the bottom plate is 8.0mm, prevent at coil winding machine when operation coiling thimble stressed excessive and make the sealing offset plate impaired, destroy the sealing of mould, after appearance panel and external mold assemble, the uniform glass cement of smearing thickness all around, because poured with epoxy resin belongs to one-time formed fiberglass body, guarantee that the sealing in the casting process is very important, so unitary mould needs the special-purpose meter cabinet frame that press-fits to press-fit, accurately arrange the position of screw rod, make screw rod bear tension uniform, mold integral is stressed, stable.
