Abstract

A nondestructive detection method of internal thread core on precise tube includes selecting proper size of large block amorphous alloy, placing internal thread core in temperature controlled heating jacket by pincer like head and starting up heating, setting blank of said amorphous alloy in groove of base and leading inert gas in, using screw to drive pincer like head to let said core contact with said blank for carrying out replication, unloading and taking out large block amorphous alloy for cooling. The device used for realizing said method is also disclosed.

Description

Technical field: [0001] The invention relates to the technical field of precision internal thread pipe mold testing, in particular to a non-destructive detection method and detection device for a precision pipe internal thread core head, especially suitable for the non-destructive detection of the tooth shape of a small-diameter seamless precision copper pipe internal thread core head. detection. Background technique: [0002] Today, the destruction of the ozone layer has become one of the global environmental issues of concern to all countries, and an international unified action to protect the ozone layer has been formed to step up the elimination of ozone-depleting substances on a global scale. According to the "Montreal Agreement on Substances that Deplete the Ozone Layer" adopted in 1987, the use of CFC refrigerants has been restricted since July 1980. At the Copenhagen Conference in 1992, it was determined to abolish the use of CFC and limit the production of HCFC. A...
