Abstract
The invention relates to a micro-arc spot welding process for the secondary coil terminal lug of an ignition coil, comprising the two steps of removing oxidation layer and micro-arc spot welding. Firstly, the winding position of the secondary coil terminal lug is polished by a fine emery paper; subsequently, the micro-arc spot welding is carried out at the winding position according to the setup parameters and the operation standard so as to lead the melted metal to form a solder joint ball, thus covering the secondary winding end at the winding position of the secondary coil terminal lug; and after arc-extinguishing, the argon is postponed to be closed for 0.5 seconds so as to protect the cooling and solidification of the solder joint ball. Compared with the general electric soldering iron welding process, the micro-arc welding process has the advantages of containing no lead, environment protection, having no harm to human, high spot welding efficiency, smooth solder joint ball, covering the secondary winding end at the winding position of the secondary coil terminal lug, thus preventing point discharge and improving the durability of the ignition coil.
Description
Technical field
The present invention relates to the micro-arc spot welding process of the secondary coil terminal lug of a kind of welding procedure, particularly a kind of ignition coil.
Background technology
The welding of the secondary coil terminal lug of ignition coil, what adopt usually is the electric iron welding procedure.Before the weldering, at first need remove the oxide layer on the lug plate, with being coated with the last layer solder(ing) paste after the fine sandpaper polishing; Secondly zinc-plated on this lug plate with the thermoelectric solder horn of band tin.Electric iron and horizontal plane angle are 60 ° during weldering, and the tin of fusing is flow on the lug plate from solder horn, and be 1～3 second weld time.Postwelding, lug plate position keep motionless, and treating can after the tin cooled and solidified at solder joint place.The electric iron welding is manual operations, has lead in the scolding tin, and solder(ing) paste has certain corrosivity, and welding process may cause damage to human body and environment; Burr appears in solder joint easily, and discharge tapers off to a point; The scolding tin lazy weight can make the secondary rolling thread the end of a thread on the secondary lug plate not be capped, and discharge tapers off to a point.
Summary of the invention
The objective of the invention is to propose a kind of safety, environmental protection, efficiently and avoid the micro-arc spot welding process of the secondary coil terminal lug of ignition coil point discharge.
Technical scheme of the present invention is achieved in that
At first, coiling position polishing on the secondary coil terminal lug, remove oxide layer with fine sandpaper.Secondly, produce PC-PAS301t micro-arc spot welding device, implement micro-arc spot welding, make the secondary rolling thread the end of a thread on the motlten metal formation solder joint ball covering secondary coil terminal lug coiling position with Korea S.Power supply adopts the positive polarity connection, and the positive terminal of power supply also will be parallel on the secondary coil terminal lug by contactor simultaneously.Welding parameter is set as follows table:
| Welding method | Welding current (A) | Nozzle diameter (mm) | Tungsten electrode diameter (mm) | The spot welding time (ms) | Working gas flow (L/min) | Shield gas flow rate (L/min) |
| Micro-arc spot welding | 14～20 | Φ1.2 | Cerium tungsten Φ 0.8 | 30～50 | Ar0.5 | Ar0.5 |
Delay was closed argon gas in 0.5 second with protection solder joint ball cooled and solidified after the blow-out.
The invention has the beneficial effects as follows: not leaded and solder(ing) paste, environmental protection and harmless; Finish spot welding efficient height in the single solder joint 50ms; The protective gas argon gas is an inert gas, solder joint ball any surface finish; The discharge thereby the secondary rolling thread the end of a thread on the motlten metal formation solder joint ball covering secondary coil terminal lug coiling position prevents to taper off to a point improves the ignition coil durability.
Embodiment
Embodiment is thick 0.4 millimeter micro-arc spot welding that material is the QSn6.5 secondary coil terminal lug.
At first with fine sandpaper to coiling position polishing on this secondary coil terminal lug, remove oxide layer.
Secondly, produce PC-PAS301t micro-arc spot welding device with Korea S, carry out micro-arc spot welding, power supply adopts the positive polarity connection, and the positive terminal of power supply also will be parallel on the secondary coil terminal lug by contactor simultaneously.And the parameter that is set as follows: tungsten electrode cerium tungsten, diameter 0.8mm, nozzle 1.2mm, welding current 16A, spot welding time 50ms, protective gas are argon gas, and the working gas flow is 0.5L/min, and shield gas flow rate is 0.5L/min.
During welding, earlier coiling position on this secondary coil terminal lug is vertically placed, 80 °～90 ° of welding gun top rakes, there is clearance the upper surface at nozzle and this coiling position; Secondly, serve the protective gas argon gas earlier, connect welding current again, through the welding current that breaks behind the 50ms, motlten metal forms the solder joint ball under action of gravity, cover the secondary rolling thread the end of a thread on this coiling position.Postpone 0.5s after the blow-out and close argon gas, make the solder joint ball under the protection of argon gas, rapidly cooled and solidified and any surface finish.
