Background technology
Welding machine is one of key equipment of steel mill's continuous annealing unit, and weldquality is directly connected to the roller consumption of unit surface quality of products, logical plate ability and working roll.
At present, to detect mainly be whether having cracking judge weldquality through hit with a hammer commissure three times of manual work if detecting by an unaided eye then to the weldquality of continuous annealing coating unit.This method is not only consuming time, efficient is low, and accuracy in detection is low, otherness is big, therefore often takes place because the weldquality defective can't detect, and causes with the situation of steel in the commissure fracture.Weld cracking can cause broken belt, thereby can have a strong impact on the normal operation of continuous annealing unit.
Summary of the invention
The purpose of the utility model provides a kind of band steel weldquality pick-up unit, and this band steel weldquality pick-up unit can apace, automatically detect the whole piece weldquality, and occurrence positions that can the butt welded seam defective positions, and reports to the police.
According to above-mentioned utility model purpose, the utility model provides a kind of band steel weldquality pick-up unit, it comprises:
One entablature, it is fixed at the upper surface top of band steel, and said entablature is provided with chute;
One sill, it is fixed at the lower surface below of band steel, and said sill is provided with chute;
One first emission ultrasonic probe and one second emission ultrasonic probe, it all is located on the said entablature, and said two emission ultrasonic probes are equipped with roller and can slide along the chute on the entablature;
One first receives ultrasonic probe and one second receives ultrasonic probe, and it all is located on the said sill, and said two reception ultrasonic probes are equipped with roller and can slide along the chute on the sill;
One CPU, it receives ultrasonic probe with said first and the second reception ultrasonic probe is connected respectively;
Said first receives ultrasonic probe receives the first emission ultrasonic probe ultrasonic waves transmitted signal; Said second receives ultrasonic probe receives the second emission ultrasonic probe ultrasonic waves transmitted signal; Said first receives the ultrasonic probe and the first emission ultrasonic probe diagonal angle setting, and the said second reception ultrasonic probe and the second emission ultrasonic probe diagonal angle are provided with; Said CPU receives the ultrasonic signal of transmission from the first reception ultrasonic probe and the second reception ultrasonic probe, and it is discerned.
In the present technique scheme, the first emission ultrasonic probe and the second emission ultrasonic probe and first receive ultrasonic probe and the second reception ultrasonic probe can move along entablature and sill respectively, thereby adjusts the position of each ultrasonic probe.The first emission ultrasonic probe and the second emission ultrasonic probe be butt welded seam emission ultrasound wave respectively.Ultrasound wave is through behind the weld seam, receives ultrasonic probe and second by first again and receives ultrasonic probe and receive respectively, and transfer to CPU, and CPU is through the analysis to the ultrasonic signal that receives, thereby judges whether weld seam exists defective.If there is defective (like hole or crackle) in weld seam, the first and second emission ultrasonic probe ultrasonic waves transmitted are through behind the defect area, and waveform can squint, and corresponding shifted signal can be caught and identification by CPU.
In above-mentioned band steel weldquality pick-up unit, also be provided with scale along each emission ultrasonic probe with the glide direction that receives ultrasonic probe on said entablature and the sill.Through scale, band steel weldquality pick-up unit is the position of tack weld defective fast.
In above-mentioned band steel weldquality pick-up unit, also comprise an alarm lamp, it is connected with said CPU.When finding weld defect, band steel weldquality pick-up unit can be reported to the police through alarm lamp at once, thereby eliminates the accident risk that weld defect caused.
The described a kind of band steel weldquality pick-up unit of the utility model, than the existing manual detection method, this band steel weldquality pick-up unit has the following advantages:
(1) the described band steel of the utility model weldquality pick-up unit can replace artificial hammer to knock detection method detection weldquality, realizes that fully robotization detects weldquality, has not only improved work efficiency, and has improved the accuracy of weldquality inspection;
(2) the described band steel of the utility model weldquality pick-up unit can detect the whole piece weldquality more careful from the microcosmic, exactly; Thereby the accuracy rate of having avoided the manual detection method is low and the problem of otherness, has remedied the weak point that hammer knocks weld seam simultaneously;
(3) the described band steel of the utility model weldquality pick-up unit tack weld defective occurrence positions fast;
(4) the described band steel of the utility model weldquality pick-up unit can be reported to the police when the weld seam defectiveness, so that reweld, thus the possibility of elimination broken belt that weld cracking causes.
Description of drawings
Fig. 1 is the structural representation of the described band steel of the utility model weldquality pick-up unit under a kind of embodiment.
Embodiment
Below in conjunction with Figure of description and concrete embodiment the described band steel of the utility model weldquality checkout gear is done further detailed description.
Fig. 1 has shown the described band steel of the utility model weldquality pick-up unit structure in the present embodiment.As shown in Figure 1, entablature 7 is fixedly mounted on the upper surface top and lower surface below of band steel 5 respectively with sill 8 through device fixed bar 10, and is equipped with chute and scale along the chute glide direction on the entablature 7 up and down crossbeams 8.The first emission ultrasonic probe 1 and the second emission ultrasonic probe 2 are located at respectively on the entablature 7, and two emission ultrasonic probes are equipped with roller, and can slide along the chute on the entablature 7; The first reception ultrasonic probe 3 and second receives ultrasonic probe 4 and is located at respectively on the sill 8, and two reception ultrasonic probes are provided with roller equally, and can slide along the chute on the sill 8.First receives ultrasonic probe 3 and the 1 diagonal angle setting of the first emission ultrasonic probe, and receives the first emission ultrasonic probe, 1 ultrasonic waves transmitted signal; Second receives ultrasonic probe 4 and the 2 diagonal angle settings of the second emission ultrasonic probe, and receives the second emission ultrasonic probe, 2 ultrasonic waves transmitted signals.Alarm lamp 9 is fixed on the sill 8.Alarm lamp 9, first receives ultrasonic probe 3 and the second reception ultrasonic probe 4 is connected with CPU respectively.
