Abstract
The invention relates to an abrasion-resisting screw awl with a cooling groove and a chip pocket. The abrasion-resisting screw awl with the cooling groove and the chip pocket comprises an awl body (1). The chip pocket (7) is formed in the top of the awl body (1), a cutting awl (5) is axially arranged on the outer surface of the awl body (1), a plurality of tooth lines (6) are arranged on the cutting awl (5) in the radial direction, the surface of each tooth line (6) is provided with a coating (8) made of titanium, and the cooling groove (4) is axially formed in the surface of the cutting awl (5). According to the abrasion-resisting screw awl with the cooling groove and the chip pocket, the cooling groove is axially formed in the surface of the cutting awl and can cool the screw awl after cooling water is added, the screw awl is prevented from being heated by a large amount of heat produced in the process of machining a thread, and the service life of the screw awl is prolonged. In addition, the chip pocket is formed in the top of the awl body, cuttings can be discharged in time, and the screw awl is prevented from being damaged by the cuttings. The surface of the tooth lines are coated with titanium, the abrasive resistance of the screw awl is improved, the screw awl is protected, and the service life of the screw awl is prolonged.
Description
Technical field
The present invention relates to a kind of wear-resistant screw tap that is provided with cooling bath and chip pocket.
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, screw tap head does not have chip pocket in addition, the smear metal meeting producing contacts with screw tap, thereby screw tap is damaged to some extent, thereby reduces service life; Screw tap surface does not have coating, and screw tap is easily wearing and tearing in the course of the work, and service time is not long.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and offer cooling bath, chip pocket and establish cated screw tap, thereby in the process of machining screw, can prevent smear metal cone heating, discharge that smear metal and wearability are good, not easy to wear avoids damaging screw tap in time.
The object of the present invention is achieved like this:
A kind of wear-resistant screw tap that is provided with cooling bath and chip pocket, comprise cone, the cross section of described cone is cylindrical, and the bottom of described cone is provided with taper shank, described taper shank bottom is provided with through hole, the top of described cone offers chip pocket, and described chip pocket is connected 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, the surface of described each tooth line is provided with coating, and the material of described coating is titanium, and described cutting cone surface axially offers cooling bath.
The present invention is provided with the wear-resistant screw tap of cooling bath and chip pocket, and the cross section of described cone is cylindrical.
The present invention is provided with the wear-resistant 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 wear-resistant screw tap that the present invention is provided with cooling bath and chip pocket 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, increases the service life; Cone top offers chip pocket in addition, can discharge in time smear metal, avoids smear metal to damage screw tap; The surface of tooth line scribbles titanium, has increased the wearability of screw tap, has protected screw tap, increases the service life.
Accompanying drawing explanation
Fig. 1 is the wear-resistant screw tap structural representation that the present invention is provided with cooling bath and chip pocket.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation of tooth line.
Wherein:
Cone 1
Taper shank 2
Through hole 3
Chip pocket 7
Coating 8.
The specific embodiment
Referring to Fig. 1～Fig. 3, the present invention is provided with the wear-resistant screw tap of cooling bath and chip pocket, comprise cone 1, 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, described cone 1 top offers chip pocket 7, described chip pocket 7 is connected with through hole 3, the outer surface of described cone 1 is axially arranged with cutting cone 5, on described cutting cone 5, be radially provided with a plurality of tooth lines 6, the surface of described each tooth line 6 is provided with coating 8, the material of described coating 8 is titanium, described cutting cone 5 surfaces axially offer cooling bath 4, described cooling bath 4 has one at least.
The wear-resistant 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; The surface of tooth line 6 scribbles titanium, has increased the wearability of screw tap, has protected screw tap, increases the service life.
Claims (3)
