The device of the utility model can reduce badness generating probability caused by anthropogenic factors, can prevent the waste of raw materials caused by a destructive experiment monitoring mode, can be widely used in the quality monitoring of resistance single spot welding, multiple-spot welding and resistance seam welding, and thus, the quality monitoring efficiency can be improved greatly, batch of bad welding can be prevented and cost can be saved.
Description
Technical field
The present invention relates to electric resistance welding weld seam quality monitoring field, particularly a kind of electric resistance welding weld seam quality monitoring device.
Background technology
Present electric resistance welding weld seam quality monitoring be by welding is begun and production run in the product that welded carry out regular destructive test, reach the purpose of monitoring welding quality.This technology extensively adopts in commercial production, but require under the accurate day by day prerequisite in starting material rise in price at present, welding quality, adopt this method to be difficult to obtain good monitoring effect, its deficiency mainly show as the following aspects: a when electrode because of heating produces the effect that is difficult to reach real-time monitoring when micro-deformation or material composition change, cause portioned product or batch bad easily.B carries out behind production some products owing to destructive test, thus when being strengthened, damage envelope just is difficult to the product quality of guaranty period, and can only adopt remedial measures by the feedback of subsequent handling, cause production cost to increase.C is owing to operator's professional skill and operative skill is uneven, though through long-term training, still can not reach the purpose of precisely control product quality.Along with raw-material upward tendency is fierce day by day, the continuous increase of labor cost is badly in need of accurate, effective production quality control and is satisfied production status, eliminates the unfavorable factor that production status is brought.
The utility model content
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of electric resistance welding weld seam quality monitoring device, the resistance heat by utilizing the detected weld seam key point of thermal sensing element and the comparison of preset value to underheat and leak weldering and make warning, reach the effect of effective monitoring welding quality.
In order to realize that foregoing invention purpose the utility model adopts following technical scheme:
A kind of electric resistance welding weld seam quality monitoring device, comprise and be fixed on temperature-sensitive detecting element and analysis demonstration newspaper and the alarm device of electric resistance welding welding with bottom electrode, the temperature-sensitive detecting element shows that with analyzing newspaper and alarm device are connected by data line, analyze demonstration newspaper and alarm device and accept the signal of temperature-sensitive detecting element feedback, send warning by relatively sending for underheat and leaking solder joint.Above-mentioned temperature-sensitive detecting element is fixed on electric resistance welding welding bottom electrode key point place.
The invention has the beneficial effects as follows:
Use quality monitoring device of the present invention, can reduce the bad occurrence probability that human factor causes, and can save the waste of raw materials that causes by the destructive test monitor mode, can be widely used in the quality monitoring of resistance single spot welding, multiple spot welding and electric-resistance seam-welding, quality monitoring efficient is improved greatly and and can effectively prevent batch bad.
Description of drawings
Fig. 1 is the structural representation of electric resistance welding weld seam quality monitoring device.
Embodiment
Below in conjunction with instantiation the present invention is elaborated.
As shown in Figure 1, at first the temperature-sensitive detecting element is fixed on electric resistance welding welding bottom electrode key point place; Then according to Q=I
2Rt, the resistance heat data-storing of setting out each key point shows and warning device in analyzing.In the resistance welded process, the temperature-sensitive detecting element detects the heat of electric resistance welding welding with the bottom electrode key point, and detection signal feeds back to analyze by data line and shows and warning device.By the detection signal that sends and the key point resistance heat data of presetting are compared, analysis demonstration and warning device send alerting signal for the underheat and the leakage solder joint of key point; Manually in time welding condition is adjusted, accurately controlled weldquality.
1 welding material of embodiment: framework steel band, thickness 0.8mm; Welding device therefor: compression type electric-resistance seam-welding welding gear.Having set up welding condition makes it can satisfy product quality requirement fully.
At first, reach the quality fluctuation degree of product specification, determine the quantity of monitoring means according to the effective length of electric resistance welding weld seam.The temperature-sensitive detecting element is fixed on the electric resistance welding welding with bottom electrode key point place, according to Q=I
2Rt, the resistance heat data-storing that preestablishes out each key point shows and warning device in analyzing.In the resistance welded process, the temperature-sensitive detecting element detects the heat of electric resistance welding welding with the bottom electrode key point, and detection signal feeds back to analyze by data line and shows and warning device.By the detection signal that sends and the key point resistance heat data of presetting are compared, analysis demonstration and warning device send alerting signal for the underheat and the leakage solder joint of key point, manually rapidly technological parameter and equipment are adjusted, and accurately control weldquality.
Claims (2)
1, electric resistance welding weld seam quality monitoring device is characterized in that, comprises that being fixed on electric resistance welding welds the temperature-sensitive detecting element of using bottom electrode and analyze demonstration and warning device, and the temperature-sensitive detecting element is connected with analysis demonstration and warning device by data line.
2, electric resistance welding weld seam quality monitoring device as claimed in claim 1 is characterized in that, the temperature-sensitive detecting element is fixed on electric resistance welding welding bottom electrode key point place.
