Problems solved by technology

[0002] At present, some small stamping machines appearing on the market have been widely used because of their low equipment cost and can basically meet the processing requirements. However, the current stamping process for sheet metal parts still has the following disadvantages: the stamping part of the sheet metal becomes deformed after being stretched. Thin, and cracks are prone to appear on the bending part and stretching surface. The existing stamping machine lacks detection devices during the stamping process, which requires later detection, and the detection method is visual inspection, and its reliability is not high

Embodiment Construction

[0010] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, in the crack detection tool for sheet metal stamping in this embodiment, the sheet metal part 1 is installed horizontally on the stamping support seat 2, the stamping head 3 is placed above it, and the stamping die 4 is installed below it. Cavity 401, located between the stamping head 3 and the sheet metal part 1, is provided with an ultrasonic crack detection head 5 for detecting bends. There is an escape through hole 501 larger than the outer diameter of the stamping head 3 , and its periphery is an ultrasonic detection ring 502 .

[0012] The invention uses an ultrasonic crack detection head to detect the sheet metal parts in the stamping process, and detects the bending part without later detection, and compared with the naked eye detection, the detection is comprehensive and the reliability is greatly ...

Abstract

The invention relates to a crack detection tool for metal plate stamping. A metal plate is transversely arranged on stamping supporting seats. A stamping head is arranged above the metal plate. A stamping die is arranged below the metal plate and provided with a stamping cavity. An ultrasonic wave crack detection head for detecting the bent position is arranged between the stamping head and the metal plate and rotationally arranged on the stamping supporting seat on one side through a support. The center of the ultrasonic wave crack detection head is provided with an avoiding through hole with the outer diameter larger than that of the stamping head. An ultrasonic wave detection ring is arranged on the periphery of the ultrasonic wave crack detection head. According to the crack detection tool, the metal plate is detected through the ultrasonic wave crack detection head in the stamping process, double-detection is conducted on the bent position of the metal plate, and later detection is not needed; and compared with detection through naked eyes, detection is comprehensive and reliability is improved greatly.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to stamping equipment for sheet metal. Background technique [0002] At present, some small stamping machines appearing on the market have been widely used because of their low equipment cost and can basically meet the processing requirements. However, the current stamping process for sheet metal parts still has the following disadvantages: the stamping part of the sheet metal becomes deformed after being stretched. It is thin, and cracks are prone to appear on the bending part and the stretched surface. The existing stamping machine lacks detection devices during the stamping process and needs to be tested later. The detection method is visual inspection, and its reliability is not high. Contents of the invention [0003] Aiming at the above-mentioned shortcomings of the prior art, the applicant conducts research and improvement, and provides a crack detection tool ...
