Abstract

The utility model discloses an indexable milling blade with enhanced blade strength. The milling blade is of a slice-shaped structure; the point of the milling blade is provided with a rounding; and the circumference of the edge of the milling blade is provided with uniform chamfers and rounded. The defects of an original milling blade are overcome by the indexable milling blade, and the purposes of good impact resistance, good border wearing resistance and good milling effect of the blade are achieved during rough milling of a hard surface with a large cutting depth and non-uniform cutting depths.

Description

A kind of indexable milling cutter sheet that strengthens blade strength

Technical field

This use is novel to relate to the Machining Technology field, rough mills indexing machine folder cutter blade but be specifically related to a kind of universal plane that is used on the plain-milling machine.

Background technology

At present, the recoverable amount of domestic old-fashioned boring and milling machine and vertical universal knee-and-column milling machine is very big, a kind of 75 plain milling cutters of a large amount of employings of these lathes, and this blade is a square, ISO international standard model is SPKN.Because this blade structure is simple, production technology is uncomplicated, and is with low content of technology, and use cost is cheap, still obtains for a long time so far, uses on a large scale.This milling cutter satisfies versatility requirement, on blade, has carried out along point of a knife direction to the descending negative land width of the face of whole cutting edge, still; Bigger in cutting-in, being interrupted under the milling situation of shock loading arranged, original structural design can't satisfy the demand of processing; Blade collapses cutter easily, and the workman needs frequent tool changing, when serious even can damage cutter, lathe, faulty part, cause that personnel injure etc.; Have a strong impact on processing progress; The cutter consumption costs also sharply increases, and brings great loss to factory, needs badly this milling cutter is further improved.

The utility model content

The purpose of this utility model is to overcome the deficiency of above-mentioned cutter blade; Provide a kind of and can strengthen blade strength; Guarantee that the ability of blade shock resistance, anti-boundary wear is good, the general cutter blade that replaces that milling effect is good in big cutting-in, when inhomogeneous cutting-in has the sclerderm surface to rough mill.

This use is novel for solving the problems of the technologies described above the technical scheme that is adopted to be: a kind of replaced cutter blade that strengthens blade strength; Said cutter blade is a laminated structure; The point of a knife of said cutter blade is provided with rounding, has evenly negative chamfered edge one week of cutting edge of said cutter blade, and sphering.

As the further improvement of the utility model, described cutter blade is tetragonal laminated structure.

As the further improvement of the utility model, said cutter blade point of a knife rounding is 4-R1.6, has strengthened blade point of a knife intensity, has improved the blade shock resistance greatly.

Further improvement as the utility model; Said cutter blade is along evenly negative land width of the face 0.2 ~ 0.25 of one week of cutting edge, angle-20, cutting edge sphering R0.04 ~ 0.05; Improve cutter blade in big cutting-in, when inhomogeneous cutting-in has the sclerderm surface to rough mill, the ability of blade shock resistance, anti-boundary wear.

In sum, the utility model has overcome the deficiency of original cutter blade, has realized that the ability of blade shock resistance, anti-boundary wear is good, the purpose that milling effect is good in big cutting-in, when inhomogeneous cutting-in has the sclerderm surface to rough mill.

Description of drawings

The structural representation of Fig. 1 the utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the sketch map of the negative chamfered edge of the utility model.

The specific embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, a kind of replaced cutter blade that strengthens blade strength, said cutter blade are the quadrangle laminated structure, and the point of a knife 1 of cutter blade is provided with rounding, have evenly negative chamfered edge 32 one weeks of cutting edge of said cutter blade, and sphering.

As further describing of present embodiment, cutter blade point of a knife rounding is 4-R1.6, has strengthened blade point of a knife intensity, has improved the blade shock resistance greatly.

As further describing of present embodiment; Cutter blade is along evenly negative land width of the face 0.2 ~ 0.25 of one week of cutting edge, angle-20, cutting edge sphering R0.04 ~ 0.05; Improve cutter blade in big cutting-in, when inhomogeneous cutting-in has the sclerderm surface to rough mill, the ability of blade shock resistance, anti-boundary wear.

In manufacture process; The profile of cutter blade is after compacting, sinter molding; Leave the stock removal of surplus 0.2mm along a square week, blade top and bottom; One week of insert shape and top and bottom all adopt the mode of carbide alloy complete wear to carry out, and adopt the mode of grinding to guarantee negative chamfered edge value (0.2 ,-20), seamed edge sphering value R0.04 ~ 0.05 at last.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
