Description

Technical Field

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

[0002] Tip taps are an important component of machining tools, mainly used for threaded hole machining. With the development of the machinery industry, users have put forward higher requirements for product machining quality, machining reliability, machining efficiency and tool delivery time.

[0003] The current publication number CN 221910146 U discloses a special high-temperature alloy tip tap, including a tap structure. The tap mechanism includes a cutting head, a small groove in the cutting head, a shank, a neck, a rake angle, a clearance angle, a core, and a straight groove. The cutting head has a large rake angle on the front face and a large clearance angle on the back face. The core is a positive cone structure with a straight groove. One side of the straight groove has an oblique groove to form an angle, and the chips are discharged forward along the direction of the feed. The chip removal groove of this utility model is designed with a large oblique angle and a large rake angle. The large rake angle and large clearance angle are used to achieve stable cutting, light cutting, no possibility of tool entanglement, and smooth chip removal. It avoids the vibration and tool deflection caused by work hardening during machining. The positive cone structure of the core improves the strength of the tool and is more conducive to tapping. It solves the problems of work hardening during the machining of existing tip taps, which leads to easy wear, chipping, and low machining accuracy.

[0004] To address the issues with the use of the tip tap in the aforementioned solutions, existing technologies employ a method of designing large rake angles and large clearance angles to achieve stable cutting. However, this still results in insufficient rigidity and low wear resistance of the tip tap during use, leading to low efficiency and short service life. Utility Model Content
