Abstract
The invention relates to a screw tap with a cooling groove and a chip-containing groove. The screw tap comprises a tap body (1), a section of the tap body (1) is cylindrical, a tap handle (2) is arranged at the bottom of the tap body (1), the chip-containing groove (7) is formed in the top of the tap body (1) and communicated with a through hole (3), the through hole (3) is formed in the bottom of the tap handle (2), a cutting tap (5) is axially arranged on the outer surface of the tap body (1), a plurality of threads (6) are radially arranged on the cutting tap (5), and the cooling groove (4) is axially formed in the surface of the cutting tap (5). According to the screw tap with the cooling groove and the chip-containing groove, the cooling groove is axially formed in the surface of the cutting tap, the screw tap can be cooled after cooling water is fed, overheating of the cutting tap due to a large amount of heat produced during thread machining can be prevented, and the service life is prolonged; besides, the chip-containing groove is formed in the top of the tap body, so that cutting chips can be discharged timely, and the screw tap is prevented from being damaged by the cutting chips.
Description
(1) technical field
The present invention relates to a kind of screw tap that is provided with cooling bath and chip pocket.
(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 in the process of screw thread, thereby damage the smear metal cone, the screw tap head does not have chip pocket in addition, the smear metal meeting produced contacts with screw tap, thereby screw tap is damaged to some extent, thereby reduces service life.
(3) summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of screw tap that offers cooling bath and chip pocket is provided, thereby can prevent the heating of smear metal cone and discharge in time smear metal and avoid damaging screw tap in the process of machining screw.
The object of the present invention is achieved like this:
A kind of screw tap that is provided with cooling bath and chip pocket, 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 top of described cone offers chip pocket, described chip pocket is connected with through hole, the outer surface of described cone is axially arranged with cutting cone, radially is provided with a plurality of tooth lines on described cutting cone, and described cutting cone surface axially offers cooling bath.
The present invention is provided with the screw tap of cooling bath and chip pocket, and the cross section of described cone is cylindrical.
The present invention is provided with the screw tap of cooling bath and chip pocket, and described cooling bath has one at least.
Compared with prior art, the invention has the beneficial effects as follows:
The screw tap that the present invention is provided with cooling bath and chip pocket axially offers cooling bath on the 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, increases the service life; The cone top offers chip pocket in addition, can discharge in time smear metal, avoids smear metal to damage screw tap.
(4) accompanying drawing explanation
Fig. 1 is the screw tap structural representation that the present invention is provided with cooling bath and chip pocket.
The top view that Fig. 2 is Fig. 1.
Wherein:
Cone 1
Taper shank 2
Through hole 3
Cooling bath 4
Cutting cone 5
Tooth line 6
(5) specific embodiment
Referring to Fig. 1, the present invention is provided with the screw tap of cooling bath and chip pocket, 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 described cone 1 top offers chip pocket 7, and described chip pocket 7 is connected with through hole 3, the outer surface of described cone 1 is axially arranged with cutting cone 5, radially be provided with a plurality of tooth lines 6 on described cutting cone 5, described cutting cone 5 surfaces axially offer cooling bath 4, and described cooling bath 4 has one at least.
The screw tap that the present invention is provided with cooling bath and chip pocket 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, increases the service life; Cone 1 top offers chip pocket 7 in addition, can discharge in time smear metal, avoids smear metal to damage screw tap.
Claims (3)
