Abstract
The utility model discloses a milling cutter for forming from a cambered surface to a rail top, which comprises a cutter body, alloy hard blades and blade screws. A cutter handle mounting hole is formed in the cutter body. The cutter is provided with a molding surface formed in a way that a conical surface is connected between circular arc surfaces. The milling cutter for forming from the cambered surface to the rail top has the benefits that a point rail, an alloy steel fork center or other railway products can be effectively processed from the R16 cambered surface to the rail top at one step, the processing process is simple, the efficiency is high, and the precision of a processed finished product is high.
Description
Technical field
The utility model relates to a kind of milling cutter, relates in particular to a kind of cambered surface to tread profile milling cutter, belongs to track processing with milling machine milling cutter technical field.
Background technology
When train got into the fork road or turns to infall, track was easy to be worn.High ferro opens and large-scale operation now; Need improve the material of track to adapt to high ferro requirement fast, therefore, the track that existing track especially uses on the high ferro adopts alloy steel material mostly; Alloy steel material has high-wear resistance, can satisfy the requirement of high ferro to track.After adopting alloy steel material; Requirement on machining accuracy for this fork road just needs further to improve, and existing milling machine can not satisfy the requirement to alloy steel fork road with milling cutter, especially to the processing of track fork core R16 cambered surface to the tread section; Existing processing method adopts segmental machining; Waste time and energy, and the finished product accuracy after the processing is low, is badly in need of improving.
The utility model content
The purpose of the utility model is: a kind of cambered surface to tread profile milling cutter is provided; Solving existing milling cutter requires great effort to tread section processing time consuming to track fork core cambered surface; The technical problem that finished product accuracy after the processing is low, thus the problem that exists in the above-mentioned prior art can effectively be solved.
The purpose of the utility model is to realize through following technical proposals: a kind of cambered surface to tread profile milling cutter; Comprise cutter hub and blade; The step that said cutter hub overlaps to form for the cylinder by two joint side rounding ofves; Blade is located on the arc transiting surface of cutter hub, and said blade one side is provided with row and cuts groove, and cutter hub is provided with installing hole along the axis.
As a kind of optimal way, said blade is fixed on the cutter hub through the plum blossom screw.
As further optimal way, said blade comprises a blade, No. two blades and No. three blades, and the lateral surface of a said blade is a double wedge shape, and the lateral surface of No. two blades is a planar tooth, and the lateral surface of No. three blades is recessed profile of tooth.
As further optimal way, the convex radian of a said blade and the spill radian of No. three blades are all corresponding with the cutter hub arc transiting surface.
The effect of part is following in the utility model:
A blade, No. two blades and No. three blades, the blade of three types is provided with its cutter tooth surface according to cutter hub side radian, makes blade adapt to processing request.
Compared with prior art; The beneficial effect of the utility model: the utility model cambered surface to tread profile milling cutter; Can pitch the core cambered surface to the disposable effective processing of tread section to track; Process is simple, efficient is high, and the finished product accuracy after the processing is high, can satisfy the processing request of high ferro to alloy steel fork core.
Description of drawings
Fig. 1 is the side schematic view of the utility model cambered surface to tread profile milling cutter;
Fig. 2 is the positive part sketch map of Fig. 1.
Among the figure: cutter hub-1, No. one blade-2, No. two blade-3, No. three blade-4, plum blossom screw-5, row cuts groove-6, installing hole-7.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process are except the speciality of mutual repulsion and/or the step; All can make up by any way; Only if special narration all can be replaced by other equivalences or the alternative features with similar purpose, promptly; Only if special narration, an embodiment in a series of equivalences of each characteristic or the similar characteristics.
Like Fig. 1, shown in Figure 2, the utility model cambered surface to tread profile milling cutter comprises cutter hub 1 and blade, and said cutter hub 1 forms two radian shapes that a side has a R16 radian for the step that the cylinder by two joint side rounding ofves overlaps to form.Blade is located on the arc transiting surface of cutter hub 1, and the radian of this arc transiting surface decides according to the requirement of processing work.Said blade is fixed on the cutter hub 1 through plum blossom screw 5, and blade one side is provided with row and cuts groove 6, and chip area 6 is used for uselessly cutting timely discharge with what process produced, avoids stopping up.Cutter hub 1 is provided with installing hole 7 along the axis, through this installing hole 7 whole milling cutter is installed on the milling machine.
Specifically in the present embodiment, said blade 1 comprises blade 2, No. two blades 3 and 4 three kinds of dissimilar blades of No. three blades.The lateral surface of a said blade 2 is a double wedge shape, and the lateral surface of No. two blades 3 is a planar tooth, and the lateral surface of No. three blades 4 is recessed profile of tooth; The convex radian of a said blade 2 and the spill radian of No. three blades 4 are all corresponding with cutter hub 1 arc transiting surface.
The use flow process of the utility model:
In the alloy steel fork core process that high ferro is used, owing to have corner in the structure of alloy steel fork core, therefore, this milling cutter is provided with blade and cutter hub according to its concrete structure; It is that main blade uses face that the side of cutter hub begins to the tread section from cambered surface R16, and blade is divided into three kinds of structures, disposes to the radian of tread section according to cambered surface R16; R16 originally the section, radian is R16, blade then adopts blade No. one; Decide the cutter tooth of blade lateral surface according to radian, then from the R16 transition, this changeover portion near linear; Use No. two blade, the lateral surface cutter tooth of No. two blades carries out the transition to concave surface then for facing directly; Use No. three blade, the lateral surface of No. three blades is a concave surface, and its concavity also is that the radian according to cutter hub decides; Carry out the transition to the cylinder side, bottom surface of cutter hub at last, the radian of this moment is near linear also, adopts another No. two blades.Through cambered surface R16 is disposed blade to adapt to the processing request of workpiece to the radian of tread section, can disposablely process, save time, degree of applying is higher simultaneously, and the precision of processed finished products is able to guarantee.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
