Abstract
The utility model discloses a kind of tin nozzles, including nozzle main body, keep away a gradient and are axially threaded through nozzle main body and keep away the nozzle inner hole at gradient center, nozzle inner hole passes through tin nozzle front end face, forms spout on front end face center；Keeping away a gradient is taper, and the taper is become larger by tin nozzle front end towards nozzle main body, and the nozzle inner wall of nozzle inner hole front end is cone.The utility model guarantees nozzle inner wall finish by fine to nozzle inner wall Ultra-precision Turning guarantee grinding lines, can effectively prevent tin is viscous to stick in nozzle inner wall, nozzle easily blocks, and is not easily cleaned, and extends nozzle service life length and hoist point tin precision.
Description
Technical field
The utility model belongs to nozzle technical field, and in particular to a kind of tin nozzle.
Background technique
Scolding tin industry include the micro- soldering of high speed and precision, laser drop tin welding, laser tin ball bonding, ball bonding, tin sweat(ing) weldering etc., and
Scolding tin nozzle is a most key also part of core the most in the set system, and scolding tin nozzle dimension precision requirement is high, bright and clean
Degree concentricity and the not viscous anti-oxidant aspect of tin require quite high.
Patent CN107931764A discloses a kind of ceramic scolding tin nozzle, the nozzle body including tubulose, the nozzle sheet
The circular inner hole for being used to inject tin ball is equipped in body along its length, a structure is directly stretched in the use of the upper half side wall of the inner hole
It makes, the front end of the nozzle body is equipped with jet expansion, and the lower half side wall of the inner hole is from the upper half side wall of inner hole
The diminishing taper of the opening of joining place to jet expansion, the scolding tin nozzle use the form design of front end taper, effectively
Control card ball the case where occur；But inner hole is not handled particularly parallel, in use, it is viscous still to have a small amount of tin
It sticks in inner hole and oral area, causes tin not accurate.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of tin nozzle, by nozzle inner wall Ultra-precision Turning
Guaranteeing that grinding lines is fine, and finish guarantees Ra0.01 ~ Ra0.4, the viscous glutinous of tin can be effectively prevent, nozzle is not easy to plug,
Easy to clean, long service life and hoist point tin precision.
Technical solution provided by the utility model is as follows:
A kind of tin nozzle, including nozzle main body, keep away a gradient and axial be threaded through nozzle main body and keep away a gradient center
Nozzle inner hole, nozzle inner hole pass through tin nozzle front end face, form spout on front end face center；Keeping away a gradient is taper, institute
It states taper and is become larger by tin nozzle front end towards nozzle main body, the nozzle inner wall of nozzle inner hole front end is cone.
Preferably, the tin nozzle is integrally formed using wolfram steel material.
Preferably, the nozzle main diameter is 2.0mm-2.5mm.
Preferably, the nozzle diameter of bore is 1.1mm-1.8mm.
Preferably, angle is 10 degree ~ 30 degree between the nozzle inner wall taper.
Preferably, nozzle diameter is 0.2mm ~ 0.8mm, and the finish of nozzle inner wall is Ra0.01 ~ Ra0.4.
Preferably, the nozzle main body and the length summation for keeping away a gradient are 5mm ~ 15mm.
Compared with prior art, the utility model has following technical advantage:
(1) material is integrally formed using wolfram steel in the utility model, the machining accuracy of tin nozzle is improved, to extend tin
The service life of nozzle and improve a tin precision.
(2) by guaranteeing that grinding lines is fine and finish to nozzle inner wall Ultra-precision Turning, it is viscous to effectively prevent tin
It sticks in nozzle inner walls, spout blocking, the problems such as hardly possible cleaning.
(3) size design is very reasonable, is suitable for a variety of tin equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model
Wherein: 1, nozzle main body 2, keep away a gradient 3, nozzle inner hole 4, front end face 5, spout 6, nozzle inner wall.
Specific embodiment
The utility model is described further now in conjunction with embodiment and attached drawing.
As shown in Figure 1, being integrally formed using wolfram steel material, including nozzle master the utility model discloses a kind of tin nozzle
Body 1, keep away a gradient 2 and it is axial be threaded through nozzle main body 1 and keep away the nozzle inner hole 3 at 2 center of gradient, nozzle main body 1 and keep away
The length summation of position gradient 2 is 5mm ~ 15mm, and nozzle main body 1 is cylindrical, diameter range 2.0mm-2.5mm, in nozzle
3 diameter of hole is 1.1mm-1.8mm, and nozzle inner hole 3 passes through tin nozzle front end face 4, and spout 5, spout are formed on 4 center of front end face
5 diameters are 0.2mm ~ 0.8mm；Keeping away a gradient 2 is taper, and the taper is gradually become from tin nozzle front end face 4 to nozzle main body 1
Greatly, the nozzle inner wall 6 of 3 front end of nozzle inner hole is cone, and angle is 10 degree ~ 30 degree between 6 taper of nozzle inner wall, nozzle inner wall 6
Finish be Ra0.01 ~ Ra0.4.
