Abstract
The utility model relates to a screw tap with cooling tanks. The screw tap comprises a tap body (1), the section of the tap body (1) is circular, a tap handle (2) is arranged at the bottom of the tap body (1), a through hole (3) is arranged at 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 tooth grains (6) are radially arranged on the cutting tap (5), and the cooling tanks (4) are axially arranged on the surface of the cutting tap (5). The cooling tanks are axially arranged on the surface of the cutting tap of the screw tap, so that the screw tap can be cooled down after cooling water is fed into the cooling tanks, large quantities of heat generated in a thread machining process are prevented from over heating the cutting tap, and the service life of the screw tap is prolonged.
Description
(1) technical field
The utility model relates to a kind of screw tap that contains 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, and is easy to use, both manually actuated, also can on lathe, work, and uses very extensively aborning.General screw tap does not have cooling bath at present, in the process of screw thread, can produce a large amount of heats and make the heating of smear metal awl, thereby damage the smear metal awl, has shortened service life.
(3) summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of screw tap that offers cooling bath is provided, thereby can prevent that in the process of machining screw smear metal awl heating from avoiding damaging screw tap.
The purpose of the utility model is achieved in that
A kind of screw tap that contains cooling bath; Comprise cone, the cross section of said cone is cylindrical, and the bottom of said cone is provided with taper shank; Said taper shank bottom is provided with through hole; The outer surface of said cone is axially arranged with cutting cone, radially is provided with a plurality of tooth lines on the said cutting cone, and said cutting cone surface axially offers cooling bath.
The utility model contains the screw tap of cooling bath, and the cross section of said cone is cylindrical.
The utility model contains the screw tap of cooling bath, and said cooling bath has one at least.
Compared with prior art, the beneficial effect of the utility model is:
The screw tap that the utility model contains cooling bath axially offers cooling bath on the cutting cone surface, can cool off screw tap behind the feeding cooling water, prevents that a large amount of heats that produce make cutting cone overheated in the process of screw thread processing, increases the service life.
(4) description of drawings
Fig. 1 contains the screw tap structural representation of cooling bath for the utility model.
Wherein:
Cone 1
Taper shank 2
Through hole 3
Tooth line 6.
(5) specific embodiment
Referring to Fig. 1, the utility model contains the screw tap of cooling bath, comprises cone 1; The cross section of said cone 1 is cylindrical, and the bottom of said cone 1 is provided with taper shank 2, and said taper shank 2 bottoms are provided with through hole 3; The outer surface of said cone 1 is axially arranged with cutting cone 5; Radially be provided with a plurality of tooth lines 6 on the said cutting cone 5, said cutting cone 5 surfaces axially offer cooling bath 4, and said cooling bath 4 has one at least.
The screw tap that the utility model contains cooling bath axially offers cooling bath 4 on cutting cone 5 surfaces, can cool off screw tap behind the feeding cooling water, prevents that a large amount of heats that produce make cutting cone overheated in the process of screw thread processing, increases the service life.
Claims (3)
1. screw tap that contains cooling bath; Comprise cone (1), the cross section of said cone (1) is cylindrical, and the bottom of said cone (1) is provided with taper shank (2); Said taper shank (2) bottom is provided with through hole (3); The outer surface of said cone (1) is axially arranged with cutting cone (5), radially is provided with a plurality of tooth lines (6) on the said cutting cone (5), it is characterized in that: said cutting cone (5) surface axially offers cooling bath (4).
2. a kind of screw tap that contains cooling bath according to claim 1 is characterized in that: the cross section of said cone (1) is cylindrical.
