Description
Technical field
The utility model is a kind of superconductive current lead copperhead sheet tin shaping dies, for superconduction cable in current feed with the soldering of LTS section copperhead.
Background technology
At present, current feed be superconducting coil from low temperature to the link of room temperature transition, cross over liquid helium and liquid nitrogen two warm areas, operationally to superconducting coil conveying electric current, release during stopping store in superconducting coil exceed very high energy, bear the high voltage that repid discharge produces simultaneously.Current feed can be divided into conventional current lead-in wire (being generally copper lead-in wire) and superconductive current lead two kinds, superconductive current lead can reduce the heat transfer of room temperature to low-temperature end greatly, can reduce the refrigeration power consumption of cryogenic system compared with going between with conventional current more than 2/3, the utility model is used for superconductive current lead.
Very high technological requirement is welded with between the superconduction cable of current feed and LTS section copperhead, should ensure that in use weld can not because of crossing cold or overheated coming off, ensure again closely to weld between superconduction cable with LTS section copperhead in welding process, weld does not allow a large amount of bubbles (i.e. weld defect), could reduce the resistance of current feed like this.
Summary of the invention
The utility model discloses a kind of superconductive current lead copperhead sheet tin shaping dies, superconduction cable on superconductive current lead and the soldering of LTS section copperhead, the sheet tin be shaped is positioned in LTS section copperhead groove in welding process, heating makes sheet tin melt, can ensure that superconduction cable welds firm with LTS section copperhead and porosity is less, thus ensure that the resistance of the LTS section of current feed is minimum.Need certain temperature because sheet tin is fused into liquid, whole process carrys out monitoring objective temperature by using contact type temperature sensor and temperature measurement-control instrument, always effectively improves sheet tin and is shaped and superconduction cable and copperhead welding efficiency.
The technical solution adopted in the utility model is:
Superconductive current lead copperhead sheet tin shaping dies, it is characterized in that: include patrix, bed die, described patrix, all inner chamber is offered in bed die, patrix, bed die edge is evenly distributed with several tight fixed bolt installing hole respectively, position corresponding with upper mold cavity on patrix upper surface has annular chute, chute has venthole, hole for charging tin, bed die sidewall is evenly distributed with several heating rod installing hole, several outer ring pin installing holes are evenly distributed with around bed die inner chamber, several interior pin installing hole is evenly distributed with in bed die inner chamber, air channel is had between each interior pin installing hole.
Described superconductive current lead copperhead sheet tin shaping dies, is characterized in that: be provided with tight fixed bolt in described tight fixed bolt installing hole, patrix, bed die are fixed together by tight fixed bolt.
Described superconductive current lead copperhead sheet tin shaping dies, is characterized in that: the number of described heating rod installing hole is four, is separately installed with a heating rod in each heating rod installing hole.
Described superconductive current lead copperhead sheet tin shaping dies, is characterized in that: be separately installed with an outer ring pin in each described outer ring pin installing hole.
Described superconductive current lead copperhead sheet tin shaping dies, is characterized in that: the number of described interior pin installing hole is 7, is separately installed with an interior pin in each in pin installing hole, and the domestic end that nails on has bolt hole.
The utility model has the advantages that:
The utility model uses some heating rods to the mode of mold heated, has conveniently advantage, thus reaches predetermined temperature; Patrix has hole for charging tin and venthole, can ensure that tin liquor can be inner cavity filled smoothly when tin filling, thus reaches the as far as possible few pore object of final block tin.Have chute in patrix, can ensure that tin liquor flows in inner chamber smoothly.There is air channel between interior pin installing hole on bed die, ensure that tin liquor can flow into grooving smoothly when tin filling.
The domestic end that nails on that the utility model is arranged on bed die has bolt hole, while bolt can be utilized like this to extract some interior pins, workpiece is loosened, is easy to extracting of workpiece.
The utility model does not re-use sealing ring encapsulating method, its patrix and bed die there is the sealing surface of high roughness, during assembling, patrix and bed die make sealing surface compact fit thus reach sealing purpose by some tight fixed bolts, compare traditional sealing ring sealing means, this sealing means has not easily aging, the advantages such as simple installation.
The utility model in use has the advantages such as assembling sheet tin porosity that is simple, easy-to-use, that be shaped is low.

Embodiment
As Figure 1-3, superconductive current lead copperhead sheet tin shaping dies, include patrix 4, bed die 5, described patrix 4, all inner chamber is offered in bed die 5, patrix 4, bed die 5 edge is evenly distributed with several tight fixed bolt installing hole 12 respectively, on patrix 4 upper surface, the position corresponding with upper mold cavity has annular chute 8, chute 8 has venthole 9, hole for charging tin 10, bed die 5 sidewall is evenly distributed with several heating rod installing hole 13, several outer ring pin installing holes 14 are evenly distributed with around bed die 5 inner chamber, several interior pin installing hole 15 is evenly distributed with in bed die 5 inner chamber, air channel 11 is had between each interior pin installing hole 15.
Be provided with tight fixed bolt 6 in tight fixed bolt installing hole 12, patrix 4, bed die 5 are fixed together by tight fixed bolt 6.
The number of heating rod installing hole 13 is four, is separately installed with a heating rod 1 in each heating rod installing hole 13.
An outer ring pin 2 is separately installed with in each outer ring pin installing hole 14.
The number of interior pin installing hole 15 is 7, is separately installed with an interior pin 3 in each in pin installing hole, and interior pin 3 upper end has bolt hole 7.
In the sheet tin shaping dies course of work, first outer ring pin 2 and interior pin 3 are loaded in bed die 5, cover patrix 4, and with tight fixed bolt 6 patrix 4 and bed die 5 assembled and ensure that sealing surface fits tightly simultaneously, heating rod 1 is installed on bed die 5.Heating rod 1 pair of sheet tin shaping dies is used to be heated to more than block tin melting temperature; By block tin heating and melting to liquid, then pour in chute 8 by the tin liquor of thawing, the hole for charging tin 10 that tin liquor is connected with inner chamber by chute 8 flows in dies cavity.When tin liquor no longer flows into inner chamber also completely to chute 8, stop adding tin liquor to chute 8; And stop heating sheet tin mould at this moment.
When mold cools down is to room temperature, remove the tight fixed bolt 6 of mould, take out block tin.
Mould of the present utility model and technique solve weld in superconduction cable on superconductive current lead and LTS section copperhead soldering process and cause because porosity is large the problem that current feed resistance increases.By experiment and detect, effectively reduce the porosity of superconduction cable and LTS section copperhead soldering commissure, test finds to use the resistance of the current feed of this mould process welding to be significantly less than the current feed resistance of traditional soldering, and it is more firm that traditional soldering is compared in this soldering simultaneously.
