Abstract

The present invention relates to a kind of reamer, reamer body is alloy tool steel or hard alloy, and blade is hard alloy or cubic boron nitride.Reamer cutting tip is equipped with 4 to 8 cutters tooth, is corresponding with 4 to 8 oblique chip spaces, and inclination angle is 2 ° to 10 °.Cutter tooth uses two kinds of point of a knife structure blades, is unequally distributed blades on end face.Respectively there are one interior cooling holes for each cutter tooth and chip space of reamer.Compared with prior art, the present invention uses oblique chip space, and compared to straight trough, tool inclination angle increases 2 ° to 10 ° from 0 °, and cutting edge gradually cuts out workpiece, and cutting process is steady, improves the processing quality in hole;Using the blade of two kinds of different point of a knife structures so that not only improved blade stress condition in process but also there is the ironing process to machined surface, and be conducive to the surface quality for improving machined surface.Interior cooling hole has taken into account cooling and chip removal function, reduces the surface roughness value in processing hole, and does not influence processing efficiency.

Description

A kind of processing cast iron skewed slot reamer
Technical field
The present invention relates in a kind of mechanical processing cutter more particularly to a kind of reamer.
Background technology
Reamer has one or more cutter tooth, is a kind of cutting off the rotating knife of hole machined surface thin metal layer Tool.Reamer is for the hole after drilling (or reaming) processing on ream workpiece, primarily to improving the machining accuracy in hole, reduces The roughness on its surface is the finishing for hole and semi-finished cutter, the general very little of allowance.
Currently, the paces with mechanization are getting faster, the required precision of device to hole is also higher and higher in mechanical processing, hinge The application of knife is also just more and more.Most of reamer used at present is straight fluted reamer, because of its manufacture, inspection and sharpening side Just, straightness is good, and utilization rate is also relatively high, but its processing conditions is general, in process chip readily flow to machined Surface scratches machined surface so that the surface accuracy in hole reduces.
Invention content
The object of the present invention is to provide a kind of reamers for high accurate hole processing.
Technical scheme is as follows:
A kind of multiple-cutting-edge skewed slot reamer, including handle of a knife and cutting tip, handle of a knife one end integrally connected cutting tip are described The diameter of handle of a knife is less than the diameter of cutting tip, and the cutting tip is equipped with 4 to 8 cutting edges, and cutting tip is additionally provided with and cuts The corresponding oblique chip space of sword is cut, the angle of inclination of the chip space is 2 ° to 10 °.
The cutter hub uses alloy tool steel material or hard alloy;The blade is welded with blade, and blade material is Hard alloy or cubic boron nitride.Due to blade use hard alloy or cubic boron nitride, the heat resistance of both materials and Wearability is stronger, to ensure that the heat-resisting and wear-resisting property of blade.
The blade point of a knife of the reamer use circular arc type (A types) and the two different point of a knife structures of broken line type (Type B), two kinds Than sharp, stressing conditions are relatively good for point of a knife cross-distribution, the wherein cutting edge of cutting edge, are suitable for finishing and microstoning, And circular arc type point of a knife has certain pressing to act on machined surface during the cutting process, while meeting process conditions, be conducive to Improve the surface quality of machined surface.
The reamer cutter tooth is distributed on the circumference of end face using unequal blade spacing, and it is hard because machined material exists to avoid cutter Particle encounters the chip being bonded on hole wall and generates periodic vibration, and the dent orientation that cutter tooth is cut is caused to repeat to add It is deep.For the ease of manufacturing and measuring, cutter tooth does the equal unequal blade spacing distribution in angle between pairs of apical tooth.
The reamer carries interior cooling hole, and there is 1 interior cooling hole, these interior cooling holes to press for each cutter tooth and chip space According to being distributed in around cutter tooth and chip space for distribution of the cutter tooth on end face and Unequal distance,.Using interior cold cooling and lubricating mode Cooling and chip removal effect can be significantly promoted, so that the surface roughness value in hole substantially reduces, while not influencing processing effect Rate.
The beneficial effects of the invention are as follows:Since chip space is skewed slot, and blade is welded on cutter hub, compared to straight trough Speech, blade cutting edge inclination have increased to 2 ° to 10 ° from 0 ° so that cutting edge gradually switches in and out workpiece, therefore cutting force reduces And it is relatively uniform, cutting process is steady, improves the processing quality in hole, this is highly beneficial for finishing.It uses simultaneously The mode of two kinds of different edging structure cutter tooth cross-distributions, advantageously reduces the surface roughness in hole.Take into account cold in interior cold oil hole But with the function of chip removal, the surface roughness in hole can be reduced and do not influence processing efficiency.Since cutter head cutting end side surface is distributed Several cutting edges so that after fraising, hole precision is high and interior avoids smoothness height.

Specific implementation mode
The present invention is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
A kind of processing cast iron skewed slot reamer, structure is as shown in Figs. 1-2, and 1 diameter of handle of a knife of reamer is less than cutting tip Diameter, cutting tip are set there are six cutting edge 4 and corresponding six chip spaces 3, and wherein the angle of inclination of chip space is 4 °. Blade is welded with cutter hub, and blade material is hard alloy, and cutter hub material is tool steel.The blade uses cutting edge and blunt circle sword two The mode of the different edging structure cross-distributions of kind.Distribution mode is as shown in Figure 3.Blade is on the circumference of end face using unequal blade spacing point Cloth, distribution angle are respectively:55 °, 60 °, 65 °, 55 °, 60 °, 65 °.The diameter of reamer can be 10-50mm, to difference Cutting occasion, the total length of a diameter of 40.038mm of reamer in the present embodiment, entire reamer are 125mm.
Present invention utilizes oblique chip spaces, compare straight fluted reamer, and tool inclination angle increases to 4 ° from 0 °, and cutting edge is gradually cut Enter and cut out workpiece, therefore cutting force is uniform, cutting process is steady, improves the processing quality in hole, highly beneficial to finishing; The mode of blunt circle sword and the different edging structure blade cross-distributions of two kinds of cutting edge is used, edging structure is respectively such as Fig. 4 and Fig. 5 It is shown, the surface quality of machined surface can be effectively improved in finishing passes;Reamer cutter tooth uses on the circumference of end face The distribution mode of unequal blade spacing, it is possible to prevente effectively from because machined material there are Hard Inclusion or encounters bonding in process Chip on hole wall and the periodic vibration generated;It is opened on each cutter tooth and chip space there are one interior cooling hole 2, to simultaneous Cooling and chip removal function has been cared for, therefore surface roughness value can be substantially reduced, and has not interfered with processing efficiency.
