Abstract
The invention relates to an interrupted thread tap with a cooling groove. The interrupted thread tap comprises a screw tap body (1). The section of the screw tap body (1) is cylindrical. A taper-shank (2) is arranged at the bottom of the screw tap body (1). A through hole (3) is formed in the bottom of the taper-shank (2). A cutting cone (5) is arranged in the axial direction on the outer surface of the screw tap body (1). A plurality of tooth patterns (6) are arranged in the radial direction of the cutting cone (5). Each tooth pattern (6) comprises long teeth (7) and short teeth (8), and the long teeth (7) and the short teeth (8) are arranged at intervals. The cooling groove (4) is formed in the axial direction of the surface of the cutting cone (5). According to the interrupted thread tap with the cooling groove, the cooling groove is formed in the axial direction of the cutting cone, so that the thread tap can be cooled after water is filled into the cooling groove, and a large amount of heat generated in the machining process of threads is prevented from enabling the cutting cone to be over hot; the long teeth and the short teeth are arranged at intervals on each tooth pattern, so that cutting resistance is reduced, the thread tap is protected, and the service life is prolonged.
Description
(1) technical field
The present invention relates to a kind of interrupted thread tap that is provided with cooling bath.
(2) background technology
Screw tap is the conventional tool of processing column shape and conical internal thread, be processing various in, the cutter of small size internal thread, it is simple in structure, easy to use, both manually actuated, also can on lathe, work, and applies aborning very extensively.General screw tap does not have cooling bath at present, can produce amount of heat and make the heating of smear metal cone, thereby damage smear metal cone in the process of screw thread; The tooth distance of tooth line and width are all certain, and the stressed and cutting resistance of tooth line is very large, easily wearing and tearing, and service life is short.
(3) summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of interrupted thread tap that is provided with cooling bath is provided, thereby can prevent smear metal cone heating and cutting resistance is little avoids damaging screw tap.
The object of the present invention is achieved like this:
A kind of interrupted thread tap that is provided with cooling bath, comprise cone, the cross section of described cone is cylindrical, the bottom of described cone is provided with taper shank, and described taper shank bottom is provided with through hole, and the outer surface of described cone is axially arranged with cutting cone, on described cutting cone, be radially provided with a plurality of tooth lines, described each tooth line comprises long teeth and short tooth, described long teeth He Duan interdental septa layout, and described cutting cone surface axially offers cooling bath.
The present invention is provided with the interrupted thread tap of cooling bath, and the cross section of described cone is cylindrical.
The present invention is provided with the interrupted thread tap of cooling bath, and described cooling bath has one at least.
Compared with prior art, the invention has the beneficial effects as follows:
The interrupted thread tap that the present invention is provided with cooling bath axially offers cooling bath on cutting cone surface, and passing into after cooling water can cooling screw tap, prevents that the amount of heat that produces makes cutting cone overheated in the process of screw thread processing; On tooth line, long teeth He Duan interdental septa is arranged, in the process of screw thread processing, has reduced cutting resistance, has protected screw tap, increases the service life.
(4) accompanying drawing explanation
Fig. 1 is the interrupted thread tap structural representation that the present invention is provided with cooling bath.
Fig. 2 is the structural representation of tooth line.
Wherein:
Cone 1
Taper shank 2
Through hole 3
Long teeth 7
Short tooth 8.
(5) specific embodiment
Referring to Fig. 1 and Fig. 2, the present invention is provided with the interrupted thread tap of cooling bath, comprises cone 1, and the cross section of described cone 1 is cylindrical, the bottom of described cone 1 is provided with taper shank 2, described taper shank 2 bottoms are provided with through hole 3, and the outer surface of described cone 1 is axially arranged with cutting cone 5, are radially provided with a plurality of tooth lines 6 on described cutting cone 5, described each tooth line 6 comprises long teeth 7 and short tooth 8, described long teeth 7 and short tooth 8 intervals layouts, described cutting cone 5 surfaces axially offer cooling bath 4, and described cooling bath 4 has one at least.
The interrupted thread tap that the present invention is provided with cooling bath axially offers cooling bath 4 on cutting cone 5 surfaces, and passing into after cooling water can cooling screw tap, prevents that the amount of heat that produces makes cutting cone overheated in the process of screw thread processing; On tooth line 6, long teeth 7 and short tooth 8 intervals are arranged, in the process of screw thread processing, have reduced cutting resistance, have protected screw tap, increase the service life.
Claims (3)
