Mainly visual observation and recommendation of some testing instruments to inspect the quality of stamping parts, briefly introduce common methods for quality inspection of stamping parts in C-type high-speed punch press factory.
Visual observation method
Under good light, directly observe the surface of the stamping parts with the naked eye to see if there are obvious pits, diffuse pits, sharp pits, long pits, curved pits, shuttle pits and other obvious pit defects. The naked eye is a relatively intuitive and fast method for surface quality identification of stamping parts. It does not require too many machines and equipment. It is suitable for stamping parts with obvious defects and obvious quality problems. The metal buckles produced by the schoolbag buckle Helmet buckle Hair rope buckle Clothing metal buckle Luggage buckle Snap buckle Yacht tricycle accessories Metal buckle Press production line, such products can usually be judged by naked eye.
Low-power microscope inspection method
Put the stamping part on the stage, turn the coarse focusing screw, let the objective lens close to the stamping part, observe with the left eye and adjust the height of the lens barrel to observe the surface of the stamping part.
Laser scanner detection method
The laser scanner has high detection accuracy. The instrument can be used to detect the quality of stamping parts with high precision requirements. This method can detect almost most metal solid materials, such as aluminum, steel, brass and common stainless steel stamping parts. Scanners can be used for detection. Stainless steel or alloy terminal products, after being produced by Bullet-shaped springs Bullet-shaped terminal blocks Round head round seat wiring harness connector High-speed precision punch press, usually require precision detection of stamping parts because such products have high precision requirements. However, it is necessary to ensure that there is no large amount of oil on the metal stamping parts, and to reduce strong light sources to avoid scattering problems that affect the data and effect of stamping part detection, so as to improve the scientificity and reliability of the detection data.
Introduction, common methods for quality inspection of stamping parts in C-type high-speed punch press factory
Optical imaging detection method
Generally speaking, the detection accuracy of detection equipment is much higher than that of human vision. When using optical imaging detection method, it is necessary to use a computer to process and analyze the image. Instrument detection can detect whether there are defects on the surface of stamping parts extremely quickly and accurately, such as cracks, deformation, burrs and other defects.
Three-coordinate measuring instrument detection method
The use of three-coordinate measuring instrument is cumbersome, so according to the specific situation, if the size and accuracy requirements of some stamping parts are not very strict, it is generally not necessary to use the three-coordinate measuring instrument detection method. This method is more suitable for stamping parts with complex shapes and various tolerance value ranges that need to be precisely controlled. First, you need to understand the parameter values of the stamping parts, and then use the software for programming according to the instruction manual. The next step is data collection and making detailed reports. It is recommended that if you need to use this detection method, it is best to let personnel who have participated in professional training use it.
The above is about common methods for quality inspection of stamping parts in C-type high-speed punch press factory. In addition to the above detection methods, there are other detection methods, such as ultrasonic detection, radiographic detection, and eddy current detection. These detection methods are particularly suitable for detecting internal defects of stamping parts.
