Description

Technical Field

[0001] The utility model relates to the technical field of die casting detection, and more specifically to a flaw detection device for an inner liner protection cover. Background Art

[0002] The liner generally refers to the container whose inner core can be seen after the outer shell is peeled off. This type of container is called the liner. When the liner is in use, it needs to be protected with a protective cover to improve the safety of the liner. The liner protective cover is generally produced by die-casting during production and processing. During the die-casting process, due to improper control of die-casting conditions, improper operation, many impurities in the raw materials or poor molds, some defects will appear on the surface or inside of the die-casting, such as pores, vortex holes, shrinkage holes, shrinkage porosity, slag holes, inclusions, etc.; some of these defects exist on the surface of aluminum alloy die-castings, and some exist inside aluminum alloy die-castings. It is difficult to detect accurately by manual inspection, and the efficiency of flaw detection is low, so X-rays are needed for flaw detection.

The operation efficiency is low, the degree of automation of the device is low, and there are certain defects. It is urgent to solve this problem and improve the automated detection capability of the flaw detection device. Utility Model Content
