Embodiment Construction

[0041] see figure 1 as shown, figure 1 It is a schematic structural diagram of an embodiment of the ultrasonic sensor 10 of the present invention. In this embodiment, the ultrasonic sensor 10 includes a housing 100 , a cover 101 , a copper foil 102 , a piezoelectric chip 103 and a cable 104 . The ultrasonic sensor 10 is installed on the test equipment for detecting the vibration signal of the test equipment and converting the vibration signal into a voltage response signal.

[0042] In this embodiment, one end of the housing 100 is open, and the other end is a closed surface. The cover sheet 101 fits with the opening end of the housing 100 and is bonded to the opening end of the housing 100 . The copper foil 102 includes an upper surface and a lower surface, and the lower surface is bonded to the inner bottom surface of the closed surface of the housing 100 . The piezoelectric wafer 103 includes an upper surface and a lower surface, and the lower surface of the piezoelectr...

Abstract

A punching abnormity detection system comprises a punching machine which generates a vibration signal when working; the ultrasonic sensor is fixed on the punching machine and is used for converting the vibration signal into a voltage response signal; the data acquisition device is electrically connected to the ultrasonic sensor and is used for acquiring the voltage response signal in real time, generating a monitoring envelope curve, analyzing whether the voltage response curve deviates from the monitoring envelope curve or not, judging that the punching machine is abnormal when the voltage response curve exceeds the monitoring envelope curve and outputting an abnormal signal; and long-term vibration parameters of the production equipment are monitored, so that production interruption caused by abnormity of the equipment in the production process is predicted, and the production quality is improved.

Description

technical field [0001] The invention relates to the stamping field, in particular to a stamping abnormality detection system. Background technique [0002] In industrial production, abnormalities in production equipment, such as stamping equipment, often occur, which may cause abnormal product batches and interrupt production. Therefore, it is necessary to monitor the long-term vibration parameters of the production equipment, so as to predict the production interruption caused by the abnormality of the equipment in the production process. Contents of the invention [0003] In view of this, it is necessary to provide a stamping abnormality detection system to monitor the long-term vibration parameters of the production equipment, so as to predict the production interruption caused by the abnormality of the equipment during the production process. [0004] The ultrasonic sensor provided by one embodiment of the present invention is characterized in that it includes: [00...
