Abstract
The utility model relates to a round die threaded cutter which belongs to the thread machining tool field. The round die threaded cutter comprises a cylindrical screw die body, a cutting flat of thread, chipping teeth and chip removal holes, wherein the cutting flat of thread and the chip removal holes are arranged in the cylindrical screw die body, and the cutting flat of thread is positioned at the center of the interior of the cylindrical screw die body; the chip removal holes are arrayed outside the cutting flat of thread; and the chipping teeth are arrayed on the cutting flat of thread. The round die threaded cutter is characterized in that the chip removal hole arranged inside the cylindrical screw die body is the cone-shaped hole. The cutter is novel in conception, can remove chips automatically when threading workpieces made of any materials and is particularly applicable to the automation assembly line.
Description
Technical field:
The utility model relates to the screwing tool field, particularly the circular die screw tool.
Background technology:
The circular die screw tool is the undersized external screw thread cutter of processing, the interior shape of the chip-removal hole of current widely used circular die screw tool is cylindrical, the circular die screw tool in this cylindrical smear metal hole has the following disadvantages in actual applications: be easy to generate the round smear metal when machining screw, and fill up chip-removal hole for various reasons, the quality of the screw thread that influence processes, sometimes smear metal even need it be discharged with other accessory, thus working (machining) efficiency influenced.Especially when the bigger material of processing as pliability such as copper material, aluminium and plasticity, often to consider length to be worth doing approximately be the summation of screw thread girth to a undercut.In a single day smear metal fills up the chip-removal hole of screw die, must clear up immediately, otherwise can cause the screw thread distortion of cutting on the flank, reduces and quality problems such as size is serious overproof.Therefore in automation, full-automatic and pipelining; with existing circular die screw tool pliability and the big workpiece of plasticity are carried out mantle fiber and add man-hour; must clear up smear metal by frequent shutdown, reduce operating efficiency, thereby lost the meaning of automation and continuous productive process.
The utility model content:
The purpose of this utility model is to overcome above-mentioned defective of the prior art, and a kind of circular die screw tool of automatic chip removal is provided.This circular die screw tool is novel, filled up the blank of national standard cutter, automatically chip removal when the workpiece of any material is carried out mantle fiber has solved the problem that machining and automatic assembly line are difficult for chip breaking, difficult chip removal, greatly raising working (machining) efficiency and economic benefit.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this circular die screw tool comprises cylindrical screw die body, cutting flank, smear metal tooth and chip-removal hole, cutting flank and chip-removal hole are positioned at cylindrical screw die body inside, and the cutting flank is positioned at the center of cylindrical screw die body inside, chip-removal hole is arranged in the outside of cutting flank, the smear metal tooth row is listed on the cutting flank, and it is characterized in that: described chip-removal hole is a cone at the hole shape of cylindrical screw die body inside.
Chip-removal hole of the present utility model at the angle of the cone hole shape shape of cylindrical screw die body inside between 20 ° to 40 °.
The quantity of chip-removal hole of the present utility model is 3 to 7, and evenly distributed to staggering at the outboard shafts of cutting flank.
The utility model compared with prior art; have the following advantages: change the cylindrical chip-removal hole of traditional round screw die screw tool into conical chip-removal hole; so just make that adding the smear metal that produces man-hour can discharge chip-removal hole automatically because of the active force between self and the taper chip hole when filling full chip-removal hole; avoided fully stopping up the screw thread distortion that chip-removal hole may cause because of smear metal; greatly reduce the number of times that to shut down the cleaning smear metal in production process, improved production efficiency and yield of products.
Description of drawings:

Fig. 2 is a front view of the present utility model.
Fig. 3 is the A-A cutaway view of the utility model embodiment 1.
Fig. 4 is the A-A cutaway view of the utility model embodiment 2.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model are the undersized external screw thread cutters of processing, comprise cylindrical screw die body 1, cutting flank 2, smear metal tooth 3 and chip-removal hole 4.
Wherein, cutting flank 2 is positioned at the center of cylindrical screw die body 1 inside, in order to hold smear metal and to form blade, gets out 3 to 7 chip-removal holes 4 in cylindrical screw die body 1, and chip-removal hole 4 axially is evenly arranged in the outside of cutting flank 2.The two ends of cutting flank 2 dispose smear metal tooth 3, and cutting teeth 3 is undertaken main cutwork, and the complete thread in the middle of the cutting flank 2 partly plays calibration and guide effect.The pass of chip-removal hole 4 is a cone, and the cone angle scope of taper chip hole is between 20 ° to 40 °.
Embodiment 1: referring to Fig. 3, be the circular die screw tool of unidirectional taper chip hole.Conical chip-removal hole 4 formed angles are bigger, though smear metal to go out to consider to be worth doing direction not ideal, also can under the trochoidal surface of chip-removal hole 4 and extruding force acting in conjunction, discharge smear metal automatically.
Embodiment 2: referring to Fig. 4, be the circular die screw tool of two-way taper chip hole.Conical chip-removal hole 4 formed angles are bigger, though smear metal to go out to consider to be worth doing direction not ideal, also can under the trochoidal surface of chip-removal hole 4 and extruding force acting in conjunction, discharge smear metal automatically.
Claims (3)
1, a kind of circular die screw tool, comprise cylindrical screw die body, cutting flank, smear metal tooth and chip-removal hole, cutting flank and chip-removal hole are positioned at cylindrical screw die body inside, and the cutting flank is positioned at the center of cylindrical screw die body inside, chip-removal hole is arranged in the outside of cutting flank, the smear metal tooth is positioned at the two ends of cutting flank, and it is characterized in that: described chip-removal hole is a cone at the hole shape of cylindrical screw die body inside.
2, circular die screw tool according to claim 1 is characterized in that: described chip-removal hole at the angle of the cone hole shape shape of cylindrical screw die body inside between 20 ° to 40 °.
