Abstract
The utility model belongs to the technical field of the transformer manufacturing technology and specifically relates to a transformer low voltage winding copper foil and female recrystallization welding mould structure who arranges of copper, this structure of is including mould, die holder, the mould through removable assemble the die holder on, the mould has a pressfitting plane, the protrusion has a plurality of tooth forms on the pressfitting plane, the periphery of mould still has the installation department. The utility model discloses can realize adopting the cold pressure welding mode to weld female the arranging of copper foil and copper, just make the metal produce strong plastic deformation and form the welding method of joint through the impressed pressure under normal atmospheric temperature, make two work pieces realize the interatomic bond under solid state, combine the interface to present complicated peak valley and rough dentation's space appearance, there are a plurality of pressure points promptly, the faying face area of gained is bigger than original geometric cross section, single sharp welding seam contact surface than melting welding is bigger, resistance is littleer relatively, promote the conductibility, reducing loss. Mould structure is simple, and investment cost is low, and is pollution -free without the solder flux, have tear open transsexual.
Description
Technical field
The utility model relates to transformer manufacture technology field, the welding field of especially a kind of transformer low voltage winding Copper Foil and copper bus-bar.
Background technology
In prior art, the Copper Foil of transformer low voltage Foil winding and the connection of lead-out wire copper bar still generally adopt argon arc welding technology, and this technology requires high to workman's solder technology, easily produce burn-through, undercut, the defect such as lack of penetration, thus affect product quality; Secondly, gas welding needs to consume argon gas, electric energy, too increases manufacturing cost; Meanwhile, the health of argon arc welding to operator also has a certain impact.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides a kind of mould structure realizing transformer low voltage winding Copper Foil and copper bus-bar Cold welding.
For achieving the above object, the utility model adopts following technical scheme:
A cold-pressing welding mould structure for transformer low voltage winding Copper Foil and copper bus-bar, this structure includes mould, die holder; Mould is assembled on die holder by removable, and mould has bonding facets, is protruding with some tooth forms at bonding facets, and the periphery of mould also has installation portion.
Described mould embeds on die holder in corresponding tank, and the bonding facets of mould is concordant with the outer face of tank; Die holder is provided with buffer spring and guide finger, cushions and guiding when buffer spring and guide finger give mold work.
The transformer low voltage winding Copper Foil that the utility model provides and the cold-pressing welding mould structure of copper bus-bar, can realize adopting cold welding mode to weld with copper bus-bar Copper Foil, just make metal produce intense plastic strain by impressed pressure at normal temperatures and form the welding method of joint, two workpiece are made to realize in the solid state combining between atom, combination interface presents complicated peak valley and indenting space pattern, namely multiple pressure point is had, the original geometric cross section of faying face area ratio of gained is large, larger than the single straight bead contact surface of melting welding, resistance is relatively less, promote conductibility, reduce the wastage.The useful alloy melting loss of elements of the method also not resemble melting welding and the problem of harmful element intrusion weld seam, not only simplify welding process, also improve Welding Safety sanitary condition simultaneously.Mould structure is simple, and cost of investment is low, without solder flux, pollution-free, has changeing property, only need change the cold stamping die corresponding with material during work, also can realize automatic welding.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model one example structure schematic diagram;
Accompanying drawing 2 is Fig. 1 mould structure schematic diagram;
Accompanying drawing 3 is the utility model one implementation result schematic diagram.
detailed description of the invention:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1,2,3, the utility model is about the cold-pressing welding mould structure of a kind of transformer low voltage winding Copper Foil and copper bus-bar, and this structure includes mould 1, die holder 2; Mould 1 is assembled on die holder 2 by removable, and mould 1 has bonding facets 11, is protruding with some tooth forms 12 at bonding facets 11, and the periphery of mould 1 also has installation portion 13.In the present embodiment, installation portion 13 is a little less than bonding facets 11, and described mould 1 embeds on die holder 2 in corresponding tank, and the bonding facets 11 of mould 1 is concordant with the outer face of tank; Die holder 2 is provided with buffer spring 3 and guide finger 4, and buffer spring 3 and guide finger 4 give buffering and guiding when mould 1 works.
During work, mould 1 is assembled on die holder 2, then die holder 2 is assembled on machine, can Cold welding be implemented.Pressing machine is put into after superimposed by the welding position of Copper Foil to be welded and copper bus-bar, make Copper Foil produce intense plastic strain with copper bus-bar by mould 1 plus-pressure and formed to weld, Copper Foil and the combination interface of copper bus-bar have the pressure point 5 that the tooth form 12 on mould mates.The bonding facets 11 of mould 1 gives the weld part flattening Copper Foil and copper bus-bar, and tooth form 12 is pressed into welding position, forms pressure point, reaches Copper Foil and is connected with copper bus-bar Cold welding., die holder 2 is provided with buffer spring 3 and guide finger 7, gives buffering and guiding when mould 1 works, promotes Cold welding quality, and have protective effect.
The utility model can realize adopting cold welding mode to weld with copper bus-bar Copper Foil, just make metal produce intense plastic strain by impressed pressure at normal temperatures and form the welding method of joint, two workpiece are made to realize in the solid state combining between atom, combination interface presents complicated peak valley and indenting space pattern, namely multiple pressure point is had, the original geometric cross section of faying face area ratio of gained is large, larger than the single straight bead contact surface of melting welding, resistance is relatively less, promote conductibility, reduce the wastage.The useful alloy melting loss of elements of the method also not resemble melting welding and the problem of harmful element intrusion weld seam, not only simplify welding process, also improve Welding Safety sanitary condition simultaneously.Mould structure is simple, and cost of investment is low, without solder flux, pollution-free, has changeing property, only need change the cold stamping die corresponding with material during work, also can realize automatic welding.
Certainly; above accompanying drawing only depicts preferred embodiment of the present utility model; concerning those skilled in the art; also can make many improvement and change to above-described embodiment when not exceeding the utility model design and scope by logical analysis, reasoning, or a limited experiment, these improve and change all should belong to the claimed scope of the utility model.
