Abstract
The utility model relates to a threading tool blade, in particular to a threading tool blade for threading a workpiece, and belongs to the field of processing cutters. The threading tool blade comprises a tool body, wherein a mounting plane is formed at the bottom of the tool body; a cutting edge is fixed on the tool body; and a front tool face is formed on the cutting edge, and is connected with the tool body through a chip removing arc surface. The threading tool blade is characterized in that the included angle between the longitudinal central line of the chip removing arc surface and the mounting plane is an acute angle. The threading tool blade has the advantages that the structure is designed reasonably; as the included angle between the longitudinal central line of the chip removing arc surface and the mounting plane is the acute angle, chip accumulation is prevented, and the chip removing effect is enhanced; and over temperature of the cutting edge during the manufacturing process is avoided by preventing chip accumulation, so that the cutting edge is protected.
Description
Technical field
The utility model relates to a kind of threading tool sheet, particularly relates to a kind of threading tool sheet that is used for cutting thread on workpiece, belongs to the process tool field.
Background technology
The threading tool sheet is used for cutting thread, and it comprises cutter hub, is fixed with blade on the cutter hub, has rake face on the blade, and rake face links to each other with cutter hub through the chip removal arc surface.In the prior art threading tool sheet; The longitudinal centre line of chip removal arc surface and the angle of mounting plane are zero degree, and promptly the chip removal arc surface is parallel with mounting plane, after the threading tool sheet is installed on the knife bar like this; The chip removal arc surface is to be horizontally disposed with; Cause chip removal to have some setbacks like this, chip is piled up easily and is made that the blade temperature is too high, the blade easy fracture in process.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art and a kind of screw thread blade is provided, reasonable in design, and chip removal is effective.
The technical scheme that the utility model solves the problems of the technologies described above employing is: a kind of threading tool sheet; Comprise cutter hub; The cutter hub bottom has mounting plane, is fixed with blade on the cutter hub, has rake face on the blade; Rake face links to each other with cutter hub through the chip removal arc surface, is characterised in that: the longitudinal centre line of said chip removal arc surface and the angle of mounting plane are acute angle.
The angle of the described acute angle of the utility model is 10 °～15 °.
The angle of the described acute angle of the utility model is 12 °.
The utility model compared with prior art has following advantage and effect: reasonable in design, and the longitudinal centre line of chip removal arc surface and the angle of mounting plane are acute angle; So after the threading tool sheet was installed on the knife bar, the chip removal arc surface no longer was horizontally disposed with, but an a head taller end; Be inclined to set, chip is difficult for piling up, and has strengthened the chip removal effect; In process, prevent to make the blade temperature too high, protected blade because of talus accumulation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 be Fig. 1 A-A to the broken section structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is described further.
Referring to Fig. 1～Fig. 3, the utility model embodiment comprises cutter hub 1, is fixed with blade 2 on the cutter hub 1, and cutter hub 1 is as a whole with blade 2, is processed by carbide alloy.Have rake face 3 on the blade 2, rake face 3 links to each other with cutter hub 1 through chip removal arc surface 4, and chip removal arc surface 4 plays the effect of chip removal.The bottom of cutter hub 1 has mounting plane 6.
The longitudinal centre line 5 of chip removal arc surface 4 is a straight line, and the angle of itself and mounting plane 6 is an acute angle, and the angle of angle is 10 °～15 °, and optimal angle is 12 °.After the threading tool sheet was installed on the knife bar, chip removal arc surface 4 no longer was horizontally disposed with, but an a head taller end; Be inclined to set, chip is difficult for piling up, and has strengthened the chip removal effect; In process, prevent to make the blade temperature too high, protected blade because of talus accumulation.
