Abstract
The utility model provides an empiecement formula spline broach belongs to cutter technical field. It has been solved, and present cutter grinder decreases seriously, manufacturing cost is high, the low scheduling problem of commonality. This empiecement formula spline broach includes cutter body and tooth row, and the cutter body is head, neck, front pilot, cutting portion and afterbody in the past backward in proper order, offers row's tooth's socket of a plurality of circumference evenly distributed in the cutting portion, and tooth row installs in row tooth's socket, and the tooth is arranged and comprises a plurality of cutting teeths, and head to the afterbody orientation of highly following of cutting teeth increases progressively in proper order. The utility model has the advantages of easy operation, the partition is good, the chasing speed is fast, the commonality is high, the sexual valence relative altitude.
Description
Technical field
The utility model belongs to cutting-tool engineering field, relates to a kind of spline broach, particularly a kind of inserted-blade type spline broach.
Background technology
Broaching tool is a kind of cutter of extensive use in modern production, is mainly used in the moulding of broaching. On broaching tool surface, have many row's cutters tooth, the size and dimension of respectively arranging cutter tooth increases successively and changes to cutting out end from incision end. In the time that broaching tool is done broaching motion, every row's cutter tooth, from the lower certain thickness metal of workpiece cutting, finally obtains the desired size and dimension of workpiece. At present, broaching tool all adopts overall structure and is made up of same material, and broaching tool be subject to the being broached impact of molded surface of workpiece, need require design corresponding broaching tool according to forming surface, and cutter consumption be serious, causes production cost high.
For the problem of above-mentioned existence, people have made various improvement to spline broach, and some has also applied for patent, for example, in Chinese patent literature data, disclose a kind of assembled spline broach and applied for patent [application number: 201410676034.2; Granted publication number: CN104439501A], it is characterized in that this assembled spline broach comprises broaching tool cutter hub, is disposed with round tooth, chamfered teeth and spline tooth between the pull end of broaching tool cutter hub and targeting part and rear handle and targeting part; The spline finishing teeth rear portion of spline tooth is equiped with the calibration ring as broaching tool finish draw tooth, on calibration ring, be provided with formed by some groups of splines and circular hole, for the smoothing surperficial stage teeth of broaching.
Above-mentioned assembled spline broach assembles calibration ring on existing broaching tool cutter hub, for further smoothing broaching surface, has improved product surface fineness, has increased broaching tool service life. But because the cutter hub of this spline broach is common material, easily wearing and tearing, and versatility problem is not resolved.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provide a kind of save material, cost low, apply the general wide inserted-blade type spline broach that encloses.
The purpose of this utility model can realize by following technical proposal: a kind of inserted-blade type spline broach, comprise cutter hub and tooth row, described cutter hub is followed successively by head, neck, front pilot, cutting portion and afterbody from front to back, it is characterized in that, on described cutting portion, offer several circumferential equally distributed toothrow grooves, described tooth row is installed in toothrow groove, and described tooth row is made up of some cutting teeths, and the height of described cutting teeth increases progressively successively to caudal directions from the head.
The operation principle of this inserted-blade type spline broach: the cutter hub of this spline broach and toothrow design for split, because the height of cutting teeth increases progressively successively to caudal directions from the head, therefore on toothrow, the fore-end of cutting teeth is the roughing tooth that is cut at first product, for the roughing of product, on toothrow, the mid portion of cutting teeth is finishing tooth, for the fine finishining of product, on toothrow, the end portion of cutting teeth is finishing teeth, for the smoothing surperficial stage teeth of broaching, ensure the fineness on product cutting surface. While needing to process different splines, only need to change corresponding toothrow, therefore this spline broach can be mass, applied widely.
In above-mentioned inserted-blade type spline broach, on described tooth row, the blade anterior angle γ of cutting teeth is 16 °-20 °, relief angle α is 1 ° 30 ' ± 30 ', land f is 0.6-0.8mm, tooth pitch t is 10mm.
In above-mentioned inserted-blade type spline broach, described cutter hub material is ordinary steel 40Cr, and described tooth row material is high speed steel W 6Mo5Cr4V2. This inserted-blade type spline broach only tooth row uses high speed steel material, has both saved material, has reduced production cost, does not affect again the performance of this broaching tool.
In above-mentioned inserted-blade type spline broach, described toothrow groove be shaped as rectangle and quantity is 3.
Compared with prior art, this inserted-blade type spline broach have simple to operate, decile good, cutting speed is fast, cost performance high.
