Description
Technical field
The utility model belongs to the used scolder of welding field, relates in particular to a kind of equipment of producing lead-free solder.
Background technology
As everyone knows, lead is a kind of noxious material, and the excessive lead of absorption of human body can cause lead poisoning, and a small amount of absorption also can influence people's cognitive ability and nervous system.The plumbous use that all is under an embargo in many fields of some countries, as automobile, can and running water pipe, but prohibit lead in welding field makes slow progress always, scolder comes out to the history in existing several thousand now from utility model, the Sn/pb scolder is with its excellent performance and cheap cost, for people are extensive use of, now become the main welding material in the electronics assembling welding always.In electronics manufacturing, solder containing pb can discharge poisonous flue gas at a certain temperature, the operator is injured, and in producing the discharging of leaded waste liquid or waste material and handle after, lead can discharge and enter underground water, polluted drinking water source, the various electronic products of the discarding solder containing pb on it also can cause very important pollution.This person and environment have the solder containing pb of severe contamination like this also being extensive use of so far, and very slow to its progress of forbidding, its reason just be up to the present also to can not find a kind of can be suitable and substitute that cost is suitable with the performance of solder containing pb.
The lead-free solder of researching and developing in the prior art mainly contains Sn-Ag, Sn-Zn, several systems of Sn-Bi, but it compares with the Sn-Pb eutectic solder, and tangible deficiency is all arranged.Under 1 explanation of tabulating.
Various lead-free solder pluses and minuses in table 1 prior art
| The lead-free solder system | Mechanical performance | Hot strength | Creep properties | Ductility | Fusing point | Wetability | Cost | Other |
| Sn-Ag | Good | Good | Good | Difference | Higher 30-40 ℃ | Difference | High | |
| Sn-Zn | Good | Good | Good | Difference | Easily oxidation, perishable | |||
| Sn-In | Difference | Too high | Very easily oxidation | |||||
| Sn-Bi | Good | Good | Difference | |||||
| Sn-Sb | Difference | Poisonous slightly |
The pluses and minuses of several lead-free solders more of the prior art as can be known, its ductility is generally lower, wetability is poor, chase after its reason, one of them is exactly to use existing smelting equipment in alloy formation process, it can not realize with air isolated preferably, thereby causes the scolder that produces oxidized, makes its degradation.
The sealing property of smelting furnace of the prior art is bad, because the participation of air is arranged, makes material easily oxidized in fusion process, especially when discharging, pour the molten alloy in the crucible in mould ingot casting again with crucible by taking out in the smelting furnace, motlten metal will have more contacting with air in this process, thus, also can make a part of alloy oxidized, its fragility of lead-free solder made from such alloy is big, poor ductility, other mechanical performance is also bad, and conductivity type also reduces simultaneously.
Summary of the invention
The purpose of this utility model is to improve the deficiencies in the prior art, and a kind of equipment of the production lead-free solder that molten metal alloy and air completely cut off in the fusion process of preparation lead-free solder is provided.
The purpose of this utility model is achieved in that
The equipment of this production lead-free solder comprises a smelting furnace, it has a melting body of heater, on the lateral wall of body of heater, be provided with the electric heating heater, be provided with seal cover and body of heater formation is tightly connected in the upper end of described body of heater, what this connection was preferably removable is tightly connected, and is provided with a charging hole on described seal cover, and the bottom of described body of heater is provided with a discharging opening, on described body of heater, be provided with a bleeding point in addition, connect an exhaust tube that is tightly connected with the air intake duct of vavuum pump on it hermetically; In the internal cavity of described body of heater, be provided with crucible, on charging aperture above the described crucible, be provided with a feed pipe, described feed pipe extends upward the outside that the described charging hole that passes hermetically on the described seal cover is located at described body of heater, is provided with seal cover on the port that places the body of heater outside of described feed pipe; Be provided with a discharging opening in the bottom of described crucible, on this discharging opening, establish discharge nozzle, this discharge nozzle extends downwards the described discharging opening that the bottom by described body of heater is provided with and passes described body of heater hermetically, is provided with a seal valve on the part that places the body of heater outside of described discharge nozzle.
Crucible in this smelting furnace is up by a feed pipe charging of stretching out in the body of heater outside, seal cover with its upper end after the charging seals, start the vavuum pump that is connected with described exhaust tube, make and have higher vacuum in the body of heater, start the described heater on the body of heater then, make the metal molten in the crucible carry out melting.After treating that melting finishes, open the described valve on the described discharge nozzle, the alloy of fusion is flowed in the ingot mold be cast into ingot.
The feed pipe structure of this smelting furnace can be lived furnace sealing after making and throw in raw material in crucible easily.Body of heater is provided with bleeding point, in fusion process, make and be in vacuum state in the stove, especially bottom pass-out one discharge nozzle that designed on its output section by crucible of this smelting furnace directly stretches out body of heater, changing will be with crucible by the structure of taking out casting in the body of heater in the prior art, make in fusion process, especially be reduced to minimum with the touch opportunity of air in the molten alloy casting cycle, can guarantee that thus alloy is not oxidized basically in casting cycle.
The lead-free solder production equipment that the utility model provides by its special structure decrease in fusion process the touch opportunity of material and air, prevented its possibility oxidized in fusion process effectively, thus, it is good, cheap just can to select for use as ductility such as zinc, aluminium in the preparation lead-free solder, but very easily oxidized metallic element, make elimination fragility by the smelting furnace that the utility model provides, mechanical performance is higher, especially the product that improves greatly of ductility replaces the solder containing pb with big contaminative.
The structural representation of the smelting furnace that description of drawings Fig. 1 provides for the utility model
