Abstract
The utility model relates to a wear-resistant interrupted screw tap with a containing groove. The wear-resistant interrupted screw tap with the containing groove comprises a screw tap body (1) provided with the containing groove (4) at the top, a screw tap handle (2) is arranged at the bottom of the screw tap body (1) and provided with a through hole (3) at the bottom, the containing groove (4) and the through hole (3) are communicated, the outer surface of the screw tap body (1) is axially provided with cutting taps (5) which are radially provided with a plurality of toothed grains (6), the surface of each toothed grain (6) is provided with a coating (9) made of titanium, each toothed grain (6) comprises a long tooth (7) and a short tooth (8), and the long teeth (7) and the short teeth (8) are arranged at intervals. Since the containing groove is arranged at the top of the screw tap, cutting chips can be discharged timely during thread machining to protect the screw tap from being damaged by the cutting chips. The long teeth and the short teeth are arranged at intervals on the toothed grains, so that cutting resistance is reduced and the screw tap is protected. In addition, since the surfaces of the toothed grains are coated with titanium, wear resistance of the screw tap is improved, the screw tap is protected, and the service life of the screw tap is prolonged.
Description
(1) technical field
The utility model relates to the wear-resistant interrupted thread tap of tank in a kind of being provided with.
(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 head does not have chip pocket at present, and the smear metal meeting that in the process of screw thread, produces contacts with screw tap, thereby screw tap is damaged to some extent; The tooth distance of tooth line and width all are certain, and the stressed and cutting resistance of tooth line is very big, easy abrasion, and service life is short; The screw tap surface does not have coating, and screw tap is easy abrasion in the course of the work, and service time is not long.
(3) summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and the wear-resistant interrupted thread tap of tank in a kind of being provided with is provided, in the process of machining screw, can discharge smear metal, cutting resistance is little and wearability good, not easy to wear, thereby avoid damaging screw tap.
The purpose of the utility model is achieved in that
The wear-resistant interrupted thread tap of tank comprises cone in a kind of being provided with, and the bottom of said cone is provided with taper shank; The bottom of said taper shank is provided with through hole, and the top of said cone offers chip pocket, and said chip pocket is connected 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 the surface of said each tooth line is provided with coating; The material of said coating is a titanium, and said each tooth line comprises long teeth and brachydont, said long teeth and brachydont separation.
The wear-resistant interrupted thread tap of tank in the utility model is provided with, the cross section of said cone is cylindrical.
Compared with prior art, the beneficial effect of the utility model is:
The utility model screw tap offers chip pocket at the cone top, in the process of screw thread processing, can in time discharge smear metal, avoids smear metal to damage screw tap; Long teeth and brachydont separation on the tooth line in the process of screw thread processing, have reduced cutting resistance, have protected screw tap; The surface of tooth line scribbles titanium, has increased the wearability of screw tap, has protected screw tap, increases the service life.
(4) description of drawings
Fig. 1 is provided with the wear-resistant interrupted thread tap structural representation of interior tank for the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of tooth line.
Wherein:
Cone 1
Taper shank 2
Through hole 3
Chip pocket 4
Cutting cone 5
Tooth line 6

Coating 9.
(5) specific embodiment
Referring to Fig. 1～Fig. 3, the wear-resistant interrupted thread tap of tank comprised cone 1 in the utility model was provided with; 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; Said cone 1 top offers chip pocket 4, and said chip pocket 4 is connected with through hole 3, and 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, the surface of said each tooth line 6 is provided with coating 9, and the material of said coating 9 is a titanium; Said each tooth line 6 comprises long teeth 7 and brachydont 8, said long teeth 7 and brachydont 8 separation.
The wear-resistant interrupted thread tap of tank offered chip pocket 4 at cone 1 top in the utility model was provided with, and in the process of screw thread processing, can in time discharge smear metal, avoided smear metal to damage screw tap; Long teeth 7 and brachydont 8 separation on the tooth line 6 in the process of screw thread processing, have reduced cutting resistance, have protected 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 (2)
1. a wear-resistant interrupted thread tap that is provided with interior tank comprises cone (1), and it is characterized in that: the bottom of said cone (1) is provided with taper shank (2); The bottom of said taper shank (2) is provided with through hole (3), and the top of said cone (1) offers chip pocket (4), and said chip pocket (4) is connected 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), the surface of said each tooth line (6) is provided with coating (9), and the material of said coating (9) is a titanium; Said each tooth line (6) comprises long teeth (7) and brachydont (8), said long teeth (7) and brachydont (8) separation.
