The invention relates to a wear-resisting interrupted thread tap which comprises a tap body (1). A tap handle (2) is arranged at the bottom of the tap body (1), a through hole (3) is formed in the bottom of the tap handle (2), the through hole (3) penetrates through the tap handle (2) and the tap body (1), a cutting tap (4) is axially arranged on the outer surface of the tap body (1), a plurality of threads (5) are arranged on the cutting tap (4) in the radial direction, a coating (8) is arranged on the surface of each thread (5), the coatings (8) are made of titanium, each thread (5) comprises a long tooth (6) and a short tooth (7), and the long teeth (6) and the short teeth (7) are arranged at intervals. The long teeth and the short teeth on the threads of the wear-resisting interrupted thread tap are arranged at intervals, and in the thread processing process, cutting resistance is reduced, and the tap is protected. The surfaces of the threads are coated with the titanium, the wear resistance of the tap is increased, the tap is protected, and the service life is prolonged.
Description
(1) Technical field [0001] The invention relates to a wear-resistant jumping tooth tap. (2) Background technology [0002] Tap is a standard tool for processing cylindrical and conical internal threads. It is a tool for processing various small and medium-sized internal threads. It has a simple structure and is easy to use. It can be operated manually or on a machine tool. It is used in production. very broad. At present, the tooth pitch and width of the tooth pattern on the general tap are fixed, the force and cutting resistance of the tooth pattern are large, easy to wear, and the service life is long; the surface of the tap is not coated, and the tap is easy to wear during the working process. not long time. (3) Contents of the invention [0003] The purpose of the present invention is to overcome the above deficiencies and provide a wear-resistant jumping thread tap, which reduces the cutting resistance of the thread during thread processing, has good wear resistance...
