Description
[technical field]
This utility model relates to a kind of Trimeresurus mucrosquamatus (Cantor)., particularly relates to a kind of soldering Trimeresurus mucrosquamatus (Cantor)..
[background technology]
Welding be by heating, pressurization, or both and use, with or without packing material, make the material of workpiece reach knot
A kind of processing technique closed.Soldering is traditional welding method, and it belongs to the solder in soldering, is with electric cautery
For main tool, be aided with stannum silk heating and melting and connect the mode of metal, be widely used in electronics industry, household appliances manufacturing,
In the industries such as auto manufacturing.Along with the progress of technology, the space between pad is more and more less, and after unleaded operation,
Weld defect also increases, and therefore, soldering the most gradually from manually changing to automatization, occurs in that various tin soldering equipment.
But, either which kind of tin soldering equipment, Trimeresurus mucrosquamatus (Cantor). (also referred to as soldering tip) is one of most important of which parts all the time.Choosing
It is very important for selecting suitable Trimeresurus mucrosquamatus (Cantor)., and suitable Trimeresurus mucrosquamatus (Cantor). can make work more efficiently, increases the durable journey of Trimeresurus mucrosquamatus (Cantor).
Degree, and the Trimeresurus mucrosquamatus (Cantor). of mistake not only affects welding and can not play peak efficiency, therefore welding quality also can lower.
Soldering Trimeresurus mucrosquamatus (Cantor). is varied, in shape, is basically divided into following several: Type B (pyramid type), irons
Ferrum head is non-directional, and whole Trimeresurus mucrosquamatus (Cantor). front end all can be welded；K-type (blade type), uses knife-edge part welding,
Erect-type or draw weldering formula to weld；I type (tip), Trimeresurus mucrosquamatus (Cantor). tip children is thin, is suitable for fine welding, or welding
The situation of narrow space, it is also possible to the Xi Qiao of generation when revising welding chip；D type (flat type/flat blade screwdriver nozzle type), with criticizing
Bottle neck part is welded, and is suitable for the welding of needs many stannum amount；C-type (horseshoe type/column type of cutting sth. askew), before Trimeresurus mucrosquamatus (Cantor).
End inclined-plane part is welded, and is suitable for the welding of needs many stannum amount.
In the soldering operation of electronic water pump for automobile, through many considerations with compare, current automatic tin soldering equipment one
As use Trimeresurus mucrosquamatus (Cantor). as depicted in figs. 1 and 2, this Trimeresurus mucrosquamatus (Cantor). of the prior art includes head 1 and shoulder 2,
Shoulder 2 refers to a section that external diameter gradually changes, and head 1 refers to be connected with shoulder, external diameter keeps constant and Xi Sifa
One section of raw contact.Described head 1 is provided with a groove 3, has oblique section 4 in the side of groove 3, and stannum silk is by sending
Stannum device enters groove 3 from one end of the groove 3 with oblique section 4, and heating makes scolding tin melt to reach welding.But,
The tin feeding amount of this Trimeresurus mucrosquamatus (Cantor). is big, occurs that the probability closing on solder joint adhesion is the highest, not only waste stannum amount, the qualification rate of welding
The lowest, less than 70%, the automated production requirement of electronic water pump for automobile can not be met far away.
[utility model content]
In order to solve above problems of the prior art, this utility model provides a kind of Trimeresurus mucrosquamatus (Cantor)., it is possible to effectively carry
The qualification rate of high electronic water pump for automobile automatic welding.
This technical scheme is:
A kind of Trimeresurus mucrosquamatus (Cantor)., this Trimeresurus mucrosquamatus (Cantor). includes that head and shoulder, described head are provided with groove, and the side of described groove sets
Being equipped with oblique section, it is characterised in that the opposite side of described groove is provided with a step, described step has one along Trimeresurus mucrosquamatus (Cantor).
The tangent plane of axis direction and the step surface intersected with this tangent plane.By arranging a step, it is possible to reduce Trimeresurus mucrosquamatus (Cantor). and solder joint
Contact area, it is possible to be less likely to occur adhesion when the solder joint that welding of automotive electronic water pump spacing is closer, reduce due to
It is bad that solder joint adhesion occurs.Simultaneously as the heating of Trimeresurus mucrosquamatus (Cantor). and thermal conduction portions the most do not change, the most still
Enough heats can be produced, heat failure welding not will not be caused because of the minimizing of contact area.
Further, described step surface is plane.
Further, described step surface is right angle or obtuse angle with the angle of described tangent plane.
Further, in order to reach effectively to weld, both ensure enough contacts area of Trimeresurus mucrosquamatus (Cantor). and solder joint, the most do not made phase
Adjacent solder joint produces adhesion, a length of the 3 of above-mentioned groove～3.7mm.
Further, in order to ensure optimal welding effect and welding yield, above-mentioned tangent plane is along the length of Trimeresurus mucrosquamatus (Cantor). axis direction
Degree is 3～5mm.
Further, in order to ensure optimal welding effect and welding yield, and die sinking is easy, reduce cost, above-mentioned
Step surface is 14～16mm to the minimum distance of described shoulder.
Further, on the basis of reaching effectively to weld, in order to save stannum amount, the gap width of above-mentioned groove is
1.0～1.4mm.
This technical scheme has a following useful technique effect:
1) Trimeresurus mucrosquamatus (Cantor). that this utility model provides is capable of the connection of the closer solder joint of electronic water pump for automobile spacing；2)
Owing to being provided with a step at head, reduce the contact area of Trimeresurus mucrosquamatus (Cantor). and solder joint, it is possible at welding of automotive electronic water pump
Be less likely to occur adhesion during the closer solder joint of spacing, reduce due to solder joint adhesion occur bad, improve welding yield；
3) the most do not change due to heating and the thermal conduction portions of Trimeresurus mucrosquamatus (Cantor)., therefore remain able to produce enough heats, no
Heat failure welding not can be caused because of the minimizing of contact area, be effectively utilized heat, decrease the wave of the energy
Take；4) groove of Trimeresurus mucrosquamatus (Cantor). of the present utility model is narrower less, and the materials of Trimeresurus mucrosquamatus (Cantor). more save, and the stannum amount needed for welding is also
Less, cost reduces further, is conducive to improving the production efficiency of electronic water pump for automobile.
