Abstract
The invention discloses a four-blade tungsten steel formed milling cutter for aluminum. The four-blade tungsten steel formed milling cutter comprises a shank; a cutter head is formed on the shank, and comprises a first blade part, a second blade part, a third blade part and a fourth blade part, which are connected together in sequence; vertical side blades are formed on the first blade part; arc-shaped side blades with downward arcs are formed on the second blade part; arc-shaped side blades with upward arcs are formed on the third blade part; upward side blades are formed on the fourth blade part; the arc radiuses of the side blades of the second blade part are the same as those of the side blades of the third blade part; the upper arcs of both the second blade part and the third blade part are smaller than a quarter of the whole circle in size. The milling cutter is made of tungsten steel, the bouncing times of the cutter head of the milling cutter is reduced, and the operation stability of the formed milling cutter is enabled to be enhanced, so that the four-blade aluminum tungsten steel milling cutter is suitable for finish machining of arc wall grooves, and meanwhile, can ensure that the precision size and the consistent shapes of machined workpieces, thereby improving the production efficiency.
Description
Technical field:
The present invention relates to the technical field of milling cutter, more particularly relate to a kind of four sword aluminium tungsten steel forming milling cutters.
Background technology:
Profile milling cutter cutting edge profile is according to the milling cutter of workpiece profile design, and it can guarantee dimensional accuracy, the shape one of the workpiece to be machined higher productivity ratio of making peace.But the general present situation of groove of existing profile milling cutter institute milling is generally fairly simple, its shape is generally common square groove, dovetail groove etc., but when the comparatively complicated groove of some planforms of processing, there is certain beating in its bottom because of milling cutter, the Structural Tectonics face difficulty of processing of some circular arcs is larger, after its processing, the size of finished product is difficult to reach the requirement of expection, so the profile milling cutter of a complex structure generally can only be as slightly using compared with work, when fine finishining, often need multiple tracks milling cutter to process this, but adopt the size between its a plurality of parts of finished part of processing mode of this form generally all to have error, the uniformity of its part is poor, and adopt the processing of multiple tracks milling cutter to increase process time, thereby cause production efficiency lower.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and four sword aluminium tungsten steel forming milling cutter is provided, it utilizes wolfram steel to make profile milling cutter, has reduced beating of milling cutter, strengthened the stability of profile milling cutter operation, thus the fine finishining of applicable some circular arc wall grooves of processing.
For achieving the above object, a kind of four sword aluminium tungsten steel forming milling cutters of the present invention, comprise handle of a knife, on handle of a knife, form cutter head, cutter head is by the first blade part being connected in turn, the second blade part, the 3rd blade part and four blade blade form, on the first described blade part, form vertical side edge, the second blade part forms the downward circular arc side edge of camber line, the 3rd blade part forms the side edge of the circular arc type that camber line makes progress, four blade sword forms side edge upwards, the arc radius of the second described blade part and the side edge of the 3rd blade part equates, on the side edge of the second blade part and the 3rd blade part, circular arc is all less than in full circle 1/4 circular arc.
As technique scheme preferably, described handle of a knife and cutter head all adopt wolfram steel, the first blade part of cutter head is all identical with the diameter of handle of a knife with the diameter of four blade blade.
As technique scheme preferably, four described sword aluminium adopt the milling cutter of straight tooth shape with tungsten steel forming milling cutter.
Beneficial effect of the present invention is: it utilizes wolfram steel to make profile milling cutter, reduced beating of milling cutter tip, made to strengthen the stability of profile milling cutter operation, thereby the fine finishining of applicable some circular arc wall grooves of processing, can guarantee again that the dimensional accuracy of workpiece to be machined, shape are consistent, have improved production efficiency simultaneously.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that enlarged drawing is looked on the right side of cutter head of the present invention.
Symbol description in figure:
10, handle of a knife; 20, cutter head; 21, the first blade part; 22, the second blade part; 23, the 3rd blade part; 24, four blade blade.
The specific embodiment:
See shown in Fig. 1 and Fig. 2: four sword aluminium of the present invention comprise handle of a knife 10 with tungsten steel forming milling cutter, on handle of a knife 10, form cutter head 20, cutter head 20 is by the first blade part 21 being connected in turn, the second blade part 22, the 3rd blade part 23 and four blade blade 24 form, on the first described blade part 21, form vertical side edge, the second blade part 22 forms the downward circular arc side edge of camber line, the 3rd blade part 23 forms the side edge of the circular arc type that camber line makes progress, four blade blade 24 forms side edge upwards, the arc radius of the second described blade part 22 and the side edge of the 3rd blade part 23 equates, on the side edge of the second blade part 22 and the 3rd blade part 23, circular arc is all less than in full circle 1/4 circular arc.
Handle of a knife 10 and cutter head 20 all adopt wolfram steel, and the first blade part 21 of cutter head 20 is all identical with the diameter of handle of a knife 10 with the diameter of four blade blade 24.
Four sword aluminium adopt the milling cutter of straight tooth shape with tungsten steel forming milling cutter.
Operation principle: the present invention uses wolfram steel to make handle of a knife 10 and the cutter head 20 of its profile milling cutter, because adopting, wolfram steel there is stronger hardness and bending resistance deformation intensity, it can effectively reduce the beating of milling cutter tip of operation process, make milling cutter stablize and add when operation, and the cutter head of milling cutter is beated on the fine finishining impact of some circular arc wall grooves not quite small, on cutter head 20, form the whole section of circular arc survey side edge that 23 liang of group circular arc side edges of the second blade part 22 and the 3rd blade part combine, thereby be shaped to a special profile milling cutter for circular arc wall Pocket Machining in some, thereby met the required precision of the milling of some guiding cheekns.Because wolfram steel hardness is larger, the cutter head 20 of its making is not easy to wear simultaneously, thereby has guaranteed the dimensional accuracy of its production workpiece, has improved production efficiency.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
