Advantage that the utlity model has and good effect:
The poured with epoxy resin dry-type transformer has adopted the utility model brand-new technology scheme with coaming plate formula mould, has therefore had following characteristics:
Structure is meticulous, processing is simple, assembling is called conveniently, the accessory alternative is good, versatility is good, the form removal of group mould is fast easy, low for equipment requirements, light is suitable for, reduces greatly manufacture cost and other advantages.
Middle thin plate mould structure is meticulous, because the characteristic of poured with epoxy resin is the epoxy resin one-shot forming, if existing defective will directly cause pouring into a mould the back winding, mold design scraps, the Transformer Winding that the original thin board mold is applied in vast capacity make to go up exist is leaked material, fastening hidden danger such as not enough, novel die has been guaranteed sealing from structure, is beneficial to the release of integrated poured back stress again.
Middle thin plate Mould Machining is simple relatively, working ability to Mould Machining producer has reduced requirement, raw material are alternative to be improved, processing mode becomes the part assembling by original die sinking cast iron, shortened the production cycle of mould greatly, thereby shorten the production cycle of whole transformer, make design, production time more abundant, more nimbly and freely.
In the versatility of thin plate mould parts good, upper head plate, bottom plate press-fits suspension bracket, press-fits part etc. and can use in the Transformer Winding of other models of vast capacity is produced, and has overcome the shortcoming of the corresponding single model of rigid mould single mold.
Middle thin plate Mould design is more reasonable, assembly jig, dismounting mould are easier easily, with respect to the big rigid mould of weight at lifting transhipment, and the aspects such as fastening means of coil winding machine, middle thin plate mould reduces the workshop working strength of workers from structure, improve labor productivity, reduce because the work injury that large operation brings.
The middle thin plate mould of products with larger capacity has significantly reduced die manufacturing cost simultaneously, thereby has reduced the manufacturing cost of transformer, and the production process cost.And the structurally light suitable characteristics of middle thin plate mould can no longer be subjected to the restriction of vast capacity product mold heaviness, difficult carrying, have improved the flexibility that product design and mould use greatly.
