Abstract
The utility model discloses a welded tooth screw tap which comprises a cutter body part (1) and a cutter blade part (2), wherein the cutter body part (1) comprises a taper (3) and a taper shank (4); straight chip flutes (5) and cutting edges A (6) are arranged on the taper (3); the taper (3) is divided into a cutting segment (7) and a regulating segment (8); grooves (9) are formed on the taper (3); one end of the cutter blade part (2) is welded and fixed in the grooves (9); and the other end of the cutter blade part (2) is provided with cutting edges B (16) which are the same in tooth shape and size with that of the cutting edges A (6). The utility model has the benefits that due to the adoption of a welding structure, only cutter blades are made of common high-speed steel, high-performance powder metallurgy, hard alloy, or other materials, and the cost of one cutter is one third to one fourth that of a common machine thread tap, so the factory production and manufacture cost is lowered; and compared with a common screw tap, the welded tooth screw tap has the using effect that can completely meeting the processing requirements.
Description
Technical field
The utility model relates to a kind of internal-threading tool, particularly a kind of weldering tooth screw tap.
Background technology
Current general employing screw tap tapping in common internal thread machining is produced; When processing big specification internal thread hole; Often adopt machine tap with internal swarf passage, common machine tap and screw cutter; Screw cutter only is applicable to that work in-process uses in the heart, and machine tap with internal swarf passage, common machine tap cost an arm and a leg, and this makes has increased the manufacturing cost of factory to a certain extent; Present screw tap generally adopts integrative-structure; Be the high speed steel material manufacturing of cutter hub part and blade part, when the screw tap of such screw tap, particularly big specification by an integral body; In the time of can not re-using after the process reconditioning; Just can only scrap and can't utilize again, make the metal of this cutter, especially use the cutter of rare metal just to form very big waste.
The utility model content
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of weldering tooth screw tap is provided, and solves a large amount of waste high-speed steel of existing screw tap existence or the problem of Rare Metals Materials.
The purpose of the utility model realizes through following technical scheme: weldering tooth screw tap, and it comprises cutter hub part, blade part, cutter hub partly comprises cone and the taper shank that is welded on the cone afterbody; Cone is provided with straight chip flute and cutting edge A, and cone is divided into segment of cutting and calibration segment, and cone is provided with groove; One end of blade is weldingly fixed in the groove; A is corresponding with welding front A, welding bottom surface A, the welding back of cone respectively for the welding front B of blade part, welding bottom surface B, welding back B, and the other end of blade part is provided with and the identical and measure-alike cutting edge B of cutting edge A profile of tooth, and the grooved of straight chip flute is that rake is made up of plane A and arc surface A; Hypsokinesis face is made up of the rake face of arc surface B and blade part; Plane A and arc surface A are tangent, and rake face and arc surface B are tangent, and arc surface A and arc surface B are tangent.
Described taper shank is provided with chuck.
The utlity model has following advantage:
The utility model is owing to adopted Welding Structure; Have only blade to adopt common high-speed steel or materials such as high-performance powder metallurgy or carbide alloy, one is equivalent to common machine to the cost of cutter with 1/3～1/4 of thread tap, has reduced the price of cutter greatly; Indirect reduction the plant produced manufacturing cost; The result of use of weldering tooth screw tap is compared with regular tap, does not have tangible difference, can satisfy processing request fully.
