Abstract
The invention discloses a manufacture method for a tin bar with a core. The manufacture method comprises the steps that metal and rosin are weighed, the metal comprises, by weight, 95-97 parts of tin, 0.2-0.25 part of copper, 0.7-0.9 part of silver, 0.012-0.023 part of bismuth, 0.01-0.012 part of gold, and the rosin is 3-5 parts; the metal is put into a melting furnace to be melted; pouring is conducted through using a special mold, so that one or more through holes are formed inside a produced semi-finished product; pouring completely melted liquid in the second step into the special mold in the third step is conducted; heating the rosin is conducted; pouring the melted rosin into the through holes of the cooled semi-finished product in the fourth step is conducted. Accordingly, by means of the manufacture method for the tin bar with the core, welding procedures are simplified, the welding time is reduced, the product cost is reduced, the welding temperature is reduced, the solder splashes are fewer, and the welding effect is better.
Description
Technical field
The present invention relates to scolding tin field, particularly relate to a kind of preparation method having core tin bar.
Background technology
Existing tin bar is all solid, in the process of welding, electric welding head must be stained with some rosin, then weld to tin bar at point, otherwise, tin bar must reach higher temperature and could melt, and the too high oxidation easily causing tin bar of welding temperature, thus making weldering circle blackout, the particle of welding is larger, this operation extends weld interval, improves product cost.
Summary of the invention
The technical problem that the present invention mainly solves is to provide and a kind ofly simplifies welding step, save weld interval, reduce welding temperature, scruff tails off, welding effect better has core tin bar preparation method.
For solving the problems of the technologies described above, the invention provides a kind of preparation method having core tin bar, comprising the following steps:
(1) take metal and rosin, metal comprises 95-97 part tin, 0.2-0.25 part copper, 0.7-0.9 part silver, 0.012-0.023 part bismuth, 0.01-0.012 part gold, and rosin is 3-5 part, and described share is weight proportion,
(2) above-mentioned metal is put into melting furnace to melt, constantly stir in the process of fusing, until its abundant mixed melting,
(3) use particular manufacturing craft to build, described mould is provided with several hollow flow passage, makes the half-finished inside produced have at least one through hole,
(4) liquid melted completely in step (2) is poured in the particular manufacturing craft in step (3), obtains semi-finished product, cooling semi-finished product,
(5) heat rosin, make it fully melt,
(6) be poured into by the rosin of fusing in half-finished through hole of cooling in step (4), cooling obtains tin bar product again.
In a preferred embodiment of the present invention, in described tin bar product, the content of copper is lower than 1%, and described ratio is weight percentage.
In a preferred embodiment of the present invention, in described tin bar product, the content of cadmium is lower than 0.005%, and described ratio is weight percentage.
In a preferred embodiment of the present invention, in described tin bar product, the content of phosphorus is lower than 0.0012%, and described ratio is weight percentage.
In a preferred embodiment of the present invention, in described tin bar product, the content of sulphur is lower than 0.0006%, and described ratio is weight percentage.
The invention has the beneficial effects as follows: the present invention has the preparation method of core tin bar to simplify welding step, and save weld interval, reduce product cost, reduce welding temperature, scruff tails off, and welding effect is better.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
There is a preparation method for core tin bar, comprise the following steps:
(1) take metal and rosin, metal comprises 95-97 part tin, 0.2-0.25 part copper, 0.7-0.9 part silver, 0.012-0.023 part bismuth, 0.01-0.012 part gold, and rosin is 3-5 part, and described share is weight proportion,
(2) above-mentioned metal is put into melting furnace to melt, constantly stir in the process of fusing, until its abundant mixed melting,
(3) use particular manufacturing craft to build, described mould is provided with several hollow flow passage, makes the half-finished inside produced have at least one through hole,
(4) liquid melted completely in step (2) is poured in the particular manufacturing craft in step (3), obtains semi-finished product, cooling semi-finished product,
(5) heat rosin, make it fully melt,
(6) be poured into by the rosin of fusing in half-finished through hole of cooling in step (4), cooling obtains tin bar product again.
Owing to all containing certain impurity in metal and rosin, these impurity comprise cadmium metal, P elements and element sulphur, the tin bar that this method making is produced does not need to carry out removal of impurities to metal and rosin and is separated, as long as ensure that its impurity content is in certain limit, by semi-finished product tin bar is made with through hole, and through hole rosin fills up this frame mode, this tin bar is in the process of welding, during welding, operating temperature is lower than the tin bar of solid plain more than 20 degrees Celsius, the reduction of operating temperature, welding effect obviously improves, scruff tails off, and this tin bar inherently has a certain amount of rosin, rosin is not picked separately at needs during welding, simplify welding step, save weld interval, reduce product cost, reduce welding temperature, welding effect is better.
In addition, in described tin bar product, the content of copper is lower than 1%, and described ratio is weight percentage.
In addition, in described tin bar product, the content of cadmium is lower than 0.005%, and described ratio is weight percentage.
In addition, in described tin bar product, the content of phosphorus is lower than 0.0012%, and described ratio is weight percentage.
In addition, in described tin bar product, the content of sulphur is lower than 0.0006%, and described ratio is weight percentage.
Be different from prior art, the present invention has the preparation method of core tin bar to simplify welding step, and save weld interval, reduce product cost, reduce welding temperature, scruff tails off, and welding effect is better.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
