As a kind of optimized technical scheme, the top that described U-shaped is strengthened connecting portion flushes with the top of described two electrode shanks.
As another kind of optimized technical scheme, described reinforcement connecting portion is V-arrangement or camber line shape.
As a kind of optimized technical scheme, the width of described reinforcement connecting portion is similar to the width of described weld part.
After having adopted technique scheme, the beneficial effects of the utility model are: (1) of the present utility model some soldering tip, strengthening the connecting portion one is machined in two clearance for insulations between the electrode shank, therefore, whole some soldering tip can make through operations such as cutting processing with tungsten plate or the molybdenum plate of a monoblock, be very easy to realize, can produce in enormous quantities, improved the production efficiency of some soldering tip; (2) of the present utility model some soldering tip, the two ends of strengthening connecting portion are connected to the position of close weld part on two electrode shanks, strengthening connecting portion and weld part is equivalent to form two parallel resistances in the bottom of two electrode shanks, and make and strengthen the resistance of connecting portion greater than the resistance of weld part, therefore strengthening connecting portion can not cause two short circuits between the electrode shank.On this basis, have two tie points up and down between the whole some soldering tip both sides, the relative distortion power that two electrode shanks produce when installing, application point are transferred to the end of strengthening connecting portion by weld part; And in the welding process, welding pressure is shared jointly by weld part and reinforcement connecting portion, therefore, strengthen connecting portion weld part has been played booster action, in the welding process, the life-span of weld part is heightened significantly, and the spot welding number of times is brought up to 30,000 times to 80,000 times by original 10,000 times, the transfer matic continuous welding is reliable and stable, welding effect is also more satisfactory, and the bonding force test has reached requirement, and is reliable and stable, failure welding such as can not come off, the weld appearance form is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1. electrode shank, 2. weld part, 3. clearance for insulation is 4. strengthened connecting portion, 5. through hole.
The specific embodiment
As shown in Figure 1, a kind of welding enamel-covered wire point soldering tip, integral body is the integral piece structure, comprises that the bottom that forms 3, two electrode shanks 1 of clearance for insulation between 1, two electrode shank 1 of two electrode shanks links together by weld part 2.In clearance for insulation 3, be integrally formed with the reinforcement connecting portion 4 of bending strip, the two ends of this reinforcement connecting portion 4 are connected to the position of close weld part 2 on two electrode shanks 1, and run business into particular one or do length by strengthening connecting portion 4, make and strengthen the resistance of connecting portion 4 greater than the resistance of weld part 2.The point soldering tip of said structure can make through operations such as cutting processing with tungsten plate or the molybdenum plate of a monoblock, is very easy to realize, can produce in enormous quantities.Strengthen connecting portion 4 and be equivalent to form two parallel resistances in the bottom of two electrode shanks 1 with weld part 2, and owing to strengthen the resistance of connecting portion 4 greater than the resistance of weld part 2, therefore strengthening connecting portion 4 can not cause two short circuits between the electrode shank 1.On this basis, have two tie points up and down between the whole some soldering tip both sides, the relative distortion power that two electrode shanks 1 produce when installing, application point is transferred to the end of strengthening connecting portion 4 by weld part 2; And in the welding process, welding pressure is shared jointly by weld part 2 and reinforcement connecting portion 4, therefore, strengthen 4 pairs of weld parts 2 of connecting portion and played booster action, in the welding process, the life-span of weld part 2 is heightened significantly, and the spot welding number of times is brought up to 30,000 times to 80,000 times by original 10,000 times, the transfer matic continuous welding is reliable and stable, and welding effect is also more satisfactory.
In this implementation process, clearance for insulation 3 between two electrode shanks 1 is narrow long groove shape, corresponding, strengthen connecting portion 4 and be designed to U-shaped, this U-shaped is strengthened the top of connecting portion 4 away from weld part 2, two ends are connected to the position of close weld part 2 on two electrode shanks 1, and the intermediate gap that U-shaped is strengthened connecting portion 4 extends to weld part 2.The clearance for insulation 3 of weld part 2 tops generally is to form the breach of a sub-circular through the past material, is used for increasing the resistance of weld part 2, also is used for increasing the radiating effect of weld part 2.
In this implementation process, the top of U-shaped being strengthened connecting portion 4 flushes with the top of two electrode shanks 1, make that the length of U-shaped reinforcement connecting portion 4 is long as far as possible, make U-shaped strengthen the resistance of connecting portion 4 much larger than the resistance of weld part 2, during the work of some soldering tip, only there is very a spot of electric current to strengthen connecting portion 4 by U-shaped, can not influence the normal welding of weld part 2.The width that U-shaped is strengthened connecting portion 4 is processed into close or narrower with the width of weld part 2, is to strengthen the resistance of connecting portion 4 in order to increase U-shaped equally, realizes above-mentioned technical purpose.
Electronic spot welder has welding pressure, weldingvoltage, weld interval three groups of regulatable welding parameters.During welding, according to the line footpath of sealing wire and the different requirements of weldment, set above-mentioned three groups of parameters, when the pressure that is applied to a soldering tip reaches setting value, could trigger microswitch, make a soldering tip and host power supply form the loop turn-on current.Because it is bigger to put weld part 2 resistance of soldering tip, electric current by the time produce high temperature at weld part 2, the part of insulated paint is burnt, remainder is shunk back to two ends, expose metal wire, because the continuation effect of welding pressure, a large amount of electric currents that order about on the weld part 2 transfer to flow into bare metal line and metal wire substrate, electric energy is converted into heat energy, and moment is realized two-part welding.
Under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, for example: under the more roomy situation of clearance for insulation 3, can be designed to V-arrangement or camber line shape with strengthening connecting portion 4, can realize the technique effect in above-described embodiment equally.And these improvement and distortion; all drop in the protection domain of the present utility model; it will be understood by those skilled in the art that the just better the purpose of this utility model of explaining of above-mentioned specific descriptions, protection domain of the present utility model is limited by claim and equivalent thereof.
