Stamping device based on crack detection

Abstract

The invention relates to a stamping device based on crack detection. The stamping device is characterized in that a sheet metal part is horizontally mounted on stamping supporting seats; a stamping head is arranged above the sheet metal part, and a stamping die is mounted below the sheet metal part; a stamping cavity is formed in the stamping die; mounting through holes communicated with the stamping cavity are formed in the side surfaces of the stamping die; a first ultrasonic wave crack detection head used for detecting a stretched side surface is mounted in each mounting through hole; a second ultrasonic wave crack detection head used for detecting a bent part is arranged between the stamping head and the sheet metal part; the second ultrasonic wave crack detection head is rotatably mounted on the stamping supporting seat on one side through a bracket; a yield through hole with the diameter larger than the outer diameter of the stamping head is formed in the center of the second ultrasonic wave crack detection head; and an ultrasonic wave detection ring is arranged on the periphery of the second ultrasonic wave crack detection head. According to the stamping device, the sheet metal part is detected through adopting the ultrasonic wave crack detection heads during the stamping process, the dual detection is carried out on the stretched side surface and the bent part of the sheet metal part, and later detection is not required; besides, compared with detection through naked eyes, the detection manner has the advantages that the detection is comprehensive, and the reliability is greatly improved.

Description

Technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to sheet metal stamping equipment. Background technique [0002] At present, some small stamping machines appearing on the market have been widely used due to their low equipment cost and can basically meet the processing requirements. However, the current stamping process for sheet metal parts still has the following shortcomings: the stamping part of the sheet metal changes after stretching It is thin and prone to cracks. The existing punching machine lacks a detection device during the punching process and needs to be detected later. The detection method is visual inspection, which is not highly reliable. Summary of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the applicant has conducted research and improvement, and provided a stamping device based on crack detection, which has the characteristics of simple structure, reliable proc...
