Description

Technical Field

[0001] This utility model relates to the field of tap technology, specifically to aerospace high-temperature alloy taps. Background Technology

[0002] A tap is a tool for machining internal threads. According to its shape, it can be divided into spiral flute taps, angled taps, straight flute taps, and pipe thread taps. According to the environment in which it is used, it can be divided into hand taps and machine taps. According to its specifications, it can be divided into metric, US, and imperial taps. Taps are the most mainstream machining tool used by operators in the manufacturing industry when tapping.

[0003] A search revealed a high-temperature alloy tap with publication number CN213033829U, comprising a fixing base, a magnetic suction cylinder, and a tap body. The magnetic suction cylinder is fixed to the bottom end of the fixing base, and the tap body is positioned at the center of the bottom end of the magnetic suction cylinder. A first cavity is formed at the bottom of the magnetic suction cylinder, and a second cavity is formed above the first cavity. A retaining post is integrally formed at the upper end of the first cavity. The tap body is inserted into the first cavity, and the retaining post is engaged with the second cavity. Several vertical threaded protrusions are integrally formed around the bottom outer wall of the fixing base, and several vertical grooves are formed around the bottom outer wall of the fixing base. These grooves connect the tap body to the first cavity inside the magnetic suction cylinder and engage the retaining post with the second cavity inside the magnetic suction cylinder. Simultaneously, the magnetic suction cylinder further magnetically fixes the tap body, making the tap body easy to install, remove, and replace.

[0004] Existing high-temperature alloy taps are installed and fixed using magnetic connections. While this method is simple, the fixing effect is poor, and taps are prone to detachment during use, affecting machining results. Furthermore, the taps operate at high speeds for extended periods, resulting in relatively high temperatures and significantly shortening their lifespan. This is especially critical in aerospace applications where temperature control is paramount. Therefore, this invention provides a special high-temperature alloy tap for aerospace applications.
