Gold is a kind of unleaded environment-friendly type alloy, is in solid-state under room temperature, and fusing point is 138 DEG C.Sn-bi alloy has solid-liquid volume simultaneously
Shrinking percentage is 0.051%, has many advantages, such as stronger permeability, coating whether there is or not whisker, fusing point is low, solderability is good, external big
Amount promotes and applies, and research and application at home is then less.
Sn-bi alloy multi-pass is crossed the mode poured and is produced in the prior art, but due to preformed solder dosage essence
Standard, so solder size also very little (about 1mm), can not be produced by directly pouring.Existing preformed solder multi-pass
Overshoot pressure carries out processing synthesis, but sn-bi alloy, since its brittleness is higher, punching press is unable to get appearance and size qualification
Tin bismuth preformed solder.
Utility model content
The purpose of this utility model is that: in view of the above problems, a kind of sn-bi alloy extrusion forming device is provided,
Solve the problems, such as that the small processing of sn-bi alloy preformed solder size is complicated.
The technical solution adopted in the utility model is as follows:
A kind of sn-bi alloy extrusion forming device, including with inner cavity pipe sleeve, be set in pipe sleeve inner cavity pressure ram,
The upper cover and lower cover connecting with pipe sleeve, the upper cover and pipe sleeve detachable connection, one end of the pressure ram are connected with tube core, institute
It states tube core to be set in the inner cavity of pipe sleeve, the inner wall sliding of pipe sleeve can be bonded, the lower cover offers openable and closable discharge gate, institute
It states lower cover to be connected to pipe sleeve, is provided with electric calorifie installation on the pipe sleeve inner wall.
Since using the above structure, the detachable setting of upper cover realizes charging by opening upper cover；Then by sn-bi alloy
It is put into sn-bi alloy extrusion forming device, sn-bi alloy is molten into sn-bi alloy liquid by heating；Pass through pressure ram again
Sn-bi alloy liquid is discharged into mold from discharge gate.
Further, the driving device that driving pressure ram moves up and down is provided on the pressure ram.
Further, one end of the pressure ram extends upward through upper cover and is connected with handle.
Due to using the above structure, squeezing work by the completion of manual control pressure ram.
Further, the length of the pressure ram is greater than the length of pipe sleeve.
Further, the pressure ram is threadedly coupled with upper cover.
Further, the electric calorifie installation is connected with temperature controller.
Since using the above structure, the difference of temperature, adjusts the temperature of electric calorifie installation in pipe sleeve according to actual needs.
Further, the discharge port of the lower cover is gradually reduced along discharging direction.
Due to that using the above structure, can more accurately control the extrusion output of sn-bi alloy, while sn-bi alloy discharges
More at the uniform velocity.
Further, the lower cover and pipe sleeve detachable connection.
Since using the above structure, lower cover detachable connection can according to need difference, can replace with different sizes
The lower cover of discharge gate.It is convenient to the cleaning to lower cover and pipe sleeve inner cavity simultaneously.
Further, it is connected between the pressure ram and tube core by fixing piece.
Further, the tube core and fixing piece detachable connection.
Since the replacement of tube core using the above structure, may be implemented, the service life of product is improved.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, the utility model realizes charging by opening upper cover；Then sn-bi alloy is put into sn-bi alloy extrusion forming dress
In setting, sn-bi alloy is molten into sn-bi alloy liquid by heating；Again by pressure ram by sn-bi alloy liquid from discharge gate
It is discharged into mold, a small amount of sn-bi alloy may be implemented, reduce the cost of production, while the processing of the utility model is more
It is convenient and safe to add.
2, the discharge port of lower cover is gradually reduced along discharging direction in the utility model, can more accurately control tin bismuth
The extrusion output of alloy, while sn-bi alloy discharging is more at the uniform velocity.
