Description
Technical field
The utility model relates to rose reamer field, is specifically related to a kind of 30 ° of Special chamfer cutters.
Background technology
Rose reamer is a kind of chamfer tool in five metals processing, can rounding hole and the heterotype edge that falls.Single-blade rose reamer can be divided into, three sword rose reamers and circular hole rose reamer according to sword number; Can be divided into 60 degree according to the number of degrees, 90 degree and 120 degree of rose reamers, working standard rose reamer is φ 30*30 °, but this kind of rose reamer wants interpolation to cut adding man-hour, extremely bothers, be now designed to Special chamfer cutter, add and do not want interpolation cutting man-hour, the time improves greatly.
Utility model content
Technical problem to be solved in the utility model is to provide 30 ° of Special chamfer cutters that the simple and efficiency of a kind of structure is made laughs.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of 30 ° of Special chamfer cutters, comprise cutter head, described cutter head is provided with blade, described cutter head is connected with handle of a knife, and one jiao of described cutter head is provided with oblique angle, and the angle between described oblique angle and blade is 30 °.
On such scheme basis preferably, the material of described blade is 40Cr.
On such scheme basis preferably, described blade is formed by stacking by three blades, and tightens with nut and cutter head.
On such scheme basis preferably, described cutter head is connected by screw thread with between handle of a knife.
The beneficial effect that the utility model compared with prior art has is: be that 30 ° of angles are assemblied in milling machine between oblique angle of the present utility model and blade, drilling machine, planer, for the chamfering of 30 of processing work ° and taper hole on the lathes such as beveler, not only be applicable to the chamfering of standard machinery workpiece, be more suitable for chamfering and deburring that precision baffles angle workpiece, working standard rose reamer is that φ 30*30 adds and wants man-hour interpolation to cut, now be designed to Special chamfer cutter, add and do not want interpolation cutting man-hour, time improves greatly, now simple with new structure, and efficiency is very high, be convenient to promote, the material of blade is 40Cr, middle carbon modulation steel, cold-heading die steel and steel is moderate, handling ease, can obtain certain toughness, plasticity and wearability after suitable heat treatment, and blade is formed by stacking by three blades, and tighten with nut and cutter head, be convenient to more allowing blade replacement, be connected by screw thread between cutter head with handle of a knife, just with replacing handle of a knife or cutter head.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Number in the figure is: 1-handle of a knife, 2-cutter head, 3-blade, 4-oblique angle, 5-nut.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
It is known with reference to Fig. 1: a kind of 30 ° of Special chamfer cutters, comprise cutter head 2, described cutter head 2 is provided with blade 3, and described cutter head 2 is connected with handle of a knife 1, and one jiao of described cutter head 2 is provided with oblique angle 4, and the angle between described oblique angle 4 and blade 3 is 30 °.
Further, the material of described blade 3 is 40Cr, middle carbon modulation steel, cold-heading die steel and steel is moderate, handling ease, can obtain certain toughness, plasticity and wearability after suitable heat treatment.
Further, described blade 3 is formed by stacking by three blades, and tightens with nut 5 and cutter head 2, is convenient to more allowing blade replacement 3.
Further, described cutter head 2 is connected by screw thread with between handle of a knife 1, is connected between cutter head 2 with handle of a knife 1 by screw thread, just with replacing handle of a knife 1 or cutter head 2.
Be that 30 ° of angles are assemblied in for the chamfering of 30 ° of processing work and taper hole on the lathes such as milling machine, drilling machine, planer, beveler between oblique angle 4 of the present utility model and blade 3, not only be applicable to the chamfering of standard machinery workpiece, be more suitable for chamfering and deburring that precision baffles angle workpiece, working standard rose reamer is that φ 30*30 adds and wants man-hour interpolation to cut, now be designed to Special chamfer cutter, add and do not want interpolation cutting man-hour, time improves greatly, now simple with new structure, and efficiency is very high, be convenient to promote;
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
