Abstract

The utility model relates to a novel metal welding die which comprises a die body and a die cover, wherein, a reaction cavity, a drainage groove and a welding cavity are formed inside the die body and the die cover; the reaction cavity is isolated from the drainage groove by a steel disc; and welding powder and ignition powder are placed in the reaction cavity. After the ignition powder is ignited by means of a burning torch, the welding powder generates alumino-thermic reaction in the reaction cavity, the fusion penetration is performed to the steel disc under the high-temperature solution generated during the reaction, the high-temperature solution flows towards the welding cavity through the drainage groove, and the adjacent ends of two conductors to be connected are cast together in the welding cavity by fusion, and the intermetallic chemical welding is further finished. The utility model is free from external energy, has the characteristics of convenient carrying, high operating efficiency, and the like, and ensures the entire welding process only lasts a few seconds.

Description

The novel metal weld mold

Technical field

The utility model belongs to the mould that metal solder is used.

Background technology

Welding is to realize the firm important means that connects between the metal.Traditional welding must can be worked by the external power supply driving arrangement, and has the shortcoming that efficient is low, labour intensity is big.

The utility model content

The purpose of this utility model is, overcomes the shortcoming of conventional method welding, and the novel metal weld mold of a kind of efficient height, easy to carry, dispense with outer connecting power is provided.

The utility model mainly is made of mold, die cover, reaction chamber, drainage trough, welding chamber.Mold, die cover link by the metal duckbilled and connect, and after mold and die cover are combined, form three parts that communicate in inside: reaction chamber, drainage trough and welding chamber.In the actual use, adopt special steel dish that reaction chamber and drainage trough are kept apart, welding powder and ignition powder are positioned in the reaction chamber; And need be equipped with lighter.

Use burning torch to light after the ignition powder, thermit reaction takes place in welding powder in reaction chamber, the high temperature solution penetration steel dish that this reaction produces flows to the welding chamber by drainage trough, and abutting end founding that will two conductors to be connected in the welding chamber together, welds thereby finish intermetallic chemistry.

During use, carry out according to following step:

1. cleaning mold removes the mould aqueous vapor with the method for heating or the welding of single test character, then the metallic conductor that has cleaned is put in the reaction chamber, clips mould, makes mould driving fit place seamless as far as possible;

2. metal spacing block is put into the bottom of mould reaction chamber;

3. welding powder is poured in the reaction chamber, also stayed some pyrophoric powders on die lip;

4. cover the fusible pattern lid, again with the pyrophoric powder igniting of burning torch towards die lip;

5. during reaction is carried out, treat that metallic solution solidifies fully;

6. open mould, a complete heat release solder connector completes.

The mould of the utility model need not the external energy, has characteristics such as easy to carry, operating efficiency height, and whole welding process only needs several seconds time, is applicable to earth mat non-ferrous metal conductor welding etc.

Accompanying drawing is a three-dimensional structure diagram of the present utility model

Among the figure: the 1st, burning torch, the 2nd, die cover, the 3rd, reaction chamber, the 4th, welding agent, the 5th, steel dish, the 6th, drainage trough, the 7th, welding chamber, the 8th, ignition powder, the 9th, mold, the 10th, conductor, the 11st, conductor.

The specific embodiment is below in conjunction with embodiment of the present utility model of accompanying drawing narration

Present embodiment has mold 9, die cover 2, after the two merges, and its inner reaction chamber 8, drainage trough 6, welding chamber 7 of forming.Mold material selection density is 1.88g/cm ³High-purity hard graphite be material (1200 ℃-2500 ℃ superhigh temperature when this graphite material can bear metal molten.Under the normal condition of using, a mould can weld 80--100 point).Reaction chamber 8 links together by drainage trough 6 and welding chamber 7.Steel dish 5 is kept apart reaction chamber 3 and drainage trough 6; What steel dish 5 adopted is stainless steel material, its be placed on drainage trough 6 directly over; Place welding agent 4 in the reaction chamber 3 of steel dish 5 tops, welding agent 4 ignites ignition powder 8 by the lighter 1 that is equipped with.

During use, with two metalworks to be welded---conductor 10 and conductor 11, butt joint is carried out according to aforesaid six steps of this paper vertically, gets final product.
