Abstract
The utility model discloses arc chord angle superelevation feeding type carbide-tipped milling cutter, it comprises handle of a knife (1), neck (3), has the cutter head (2) of four sword structures, described cutter head has periphery back taper structure, and the angle of this periphery back taper structure is 3 °, the shear blade of described cutter head has shear blade back taper structure, and the angle of this shear blade back taper structure is 5 °.Compared with common four blade milling cutters, this product tool has the following advantages: 1. periphery and the large back taper of shear blade, can effectively reduce, cutting resistance and lathe load during tool sharpening large turning; 2. the special setting of bimonthly alveolus angle, solves the problem of cutter chip removal ability deficiency in high speed feed; 3. have employed the design of low helical angle under the prerequisite ensureing cutting edge cutting ability, amplitude peak can improve cutting edge strength.
Description
Technical field
The utility model relates to Model shaping process field, especially relates to a kind of arc chord angle superelevation feeding type carbide-tipped milling cutter.
Background technology
The formed machining of mould is a comparatively complicated technique, and production difficulty is also larger.The processing of high request arc corners is difficult to adopt High-speed machining usually.Present stage generally makes up the deficiency of cutting performance by reducing feeding.The high speed feed type arc chord angle milling cutter that now formed machining of ejection die is special, while improving, also carries out the decline of cost, the lifting of machined surface for Mould Machining required precision.Further, milling cutter does not have the indicating structure whether prompting is in place.
Utility model content
The purpose of this utility model is exactly to solve the problem, and provides a kind of arc chord angle superelevation feeding type carbide-tipped milling cutter.
To achieve these goals, the utility model adopts following technical scheme:
Arc chord angle superelevation feeding type carbide-tipped milling cutter, it comprises handle of a knife (1), neck (3), has the cutter head (2) of four sword structures, described cutter head has periphery back taper structure, and the angle of this periphery back taper structure is 3 °, the shear blade of described cutter head has shear blade back taper structure, and the angle of this shear blade back taper structure is 5 °.
The helical angle of described cutter head is less than or equal to 2 °.
Compared with common four blade milling cutters, this product tool has the following advantages:
1. periphery and the large back taper of shear blade, can effectively reduce, cutting resistance and lathe load during tool sharpening large turning;
2. the special setting of bimonthly alveolus angle, solves the problem of cutter chip removal ability deficiency in high speed feed;
3. have employed the design of low helical angle under the prerequisite ensureing cutting edge cutting ability, amplitude peak can improve cutting edge strength.
Accompanying drawing explanation
Fig. 1 is arc chord angle superelevation feeding type carbide-tipped milling cutter structural representation.
Fig. 2 is shear blade structural representation in arc chord angle superelevation feeding type carbide-tipped milling cutter.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the utility model further.
As shown in Figure 1-2, arc chord angle superelevation feeding type carbide-tipped milling cutter, it comprises isometrical handle of a knife 1, be located at the neck 3 of handle of a knife left part, there is the cutter head 2 of four sword structures, this cutter head is arranged in the left end of neck, described cutter head has periphery back taper structure, and the angle of this periphery back taper structure is 3 °, as can be seen from the figure, the face of cylinder to the cutter head front end of cutter head tilts (internal diameter on the face of cylinder diminishes gradually) gradually towards handle of a knife direction, the angle of this inclination is 3 °, the shear blade of described cutter head has shear blade back taper structure, and the angle of this shear blade back taper structure is 5 °, the helical angle of described cutter head equals 2 °.
The setting of crescent grinding wheel structure K, solves the problem of cutter chip removal ability deficiency in high speed feed.
Have employed low helical angle E, be intended under the prerequisite ensureing cutting edge cutting ability, amplitude peak can improve cutting edge strength.
Under dark or night-environment, whether milling cutter is in place the job stability, the reliability that are directly connected to milling cutter, Given this, the handle of a knife of this milling cutter is provided with the superlattice coating structure being used to indicate handle of a knife and whether being in place, it is the region that handle of a knife stretches into dress clip body section completely that superlattice coating structure is coated with region, if the refract light phenomenon of superlattice coating structure can be found under the environment such as night, then prove existing problems are installed, must reinstall.Super crystal lattice material after the of short duration irradiation of light, can when unglazed photograph continuous illumination, its instruction performance that what this characteristic was strong enhance.
The foregoing is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme belonging to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
