Abstract

The utility model discloses a kind of not four sword right angle milling cutters of equal part, including knife handle and cutter head, the cutter head sets that there are four the blades that are centrosymmetric, two in four blades is across the long tooth blades of center line one, other two is the short tooth blade for not spanning across center line two, described two long tooth blades are centrosymmetric, described two short tooth blades are centrosymmetric, described two long tooth blades, which all have, is located in the middle long straight line blade and the long right angle blade positioned at edge, described two short tooth blades, which all have, is located in the middle short straight line blade and the short right angle blade positioned at edge.The structural strength of the utility model blade is stronger, and the vibration that can effectively prevent and avoid cutter work in-process to generate, chip space is bigger, can more rapidly shunt iron filings, be not likely to produce built-up edge.

Description

A kind of not four sword right angle milling cutter of equal part

Technical field

The utility model relates to machining apparatus or tool, especially a kind of not four sword right angle milling cutter of equal part.

Background technique

It is existing to be used for mach milling cutter, due to the structure design of its tooth form, often result in its blade The intensity of structure is inadequate, while the vibration that not can effectively prevent and avoid cutter work in-process to generate, and cannot quickly shunt iron filings, Or the space of chip removal is inadequate, is also easy to produce built-up edge.A kind of new milling cutter is designed therefore, it is necessary to develop, it is existing to overcome There is the deficiency of technology.

Summary of the invention

For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structural strengths of blade more By force, can effectively prevent and avoid cutter work in-process to generate, vibration, chip space are bigger, can quickly shunt iron filings, be not likely to produce The four sword right angle milling cutter of not equal part of built-up edge.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of not four sword right angle milling cutter of equal part, packet Include knife handle and cutter head, the cutter head is set there are four the blade being centrosymmetric, and two in four blades is across centers The long tooth blade of line one, other two is the short tooth blade for not spanning across center line two, and described two long tooth blades are centrosymmetric, Described two short tooth blades are centrosymmetric, and described two long tooth blades, which all have, is located in the middle long straight line blade and positioned at side The long right angle blade of edge, described two short tooth blades, which all have, is located in the middle short straight line blade and the short right angle sword positioned at edge Portion.

Preferably, short polyhedron is equipped between the knife spine of described two long tooth blades and the cutting edge of adjacent short tooth blade Molding gear bottom is equipped with long polyhedron molding gear between the knife spine of described two short tooth blades and the cutting edge of adjacent long tooth blade Bottom.

Preferably, the moulding arranging of downward spiral is equipped between the knife spine of four blades and the cutting edge of adjacent blade Consider slot to be worth doing.

The beneficial effects of the utility model are: due to including knife handle and cutter head, the cutter head is set there are four being centrosymmetric Blade, two in four blades for across the long tooth blade of center line one, other two is does not span across center line two Short tooth blade, described two long tooth blades are centrosymmetric, and described two short tooth blades are centrosymmetric, described two long tooths Blade, which all has, is located in the middle long straight line blade and the long right angle blade positioned at edge, and described two short tooth blades all have position Not equal part is formed in intermediate short straight line blade and positioned at the short right angle blade at edge, two long tooth blades and two short tooth blades Flute profile design is cut, the vibration that can effectively prevent and avoid cutter work in-process to generate forms long and short polyhedron molding gear bottom shape Shape, chip space is bigger, can more rapidly shunt iron filings, be not likely to produce built-up edge, so the structural strength of the utility model blade Vibration that is stronger, can effectively prevent and avoid cutter work in-process to generate, chip space is bigger, can more rapidly shunt iron filings, no It is also easy to produce built-up edge.

Detailed description of the invention

The utility model is described in further detail with embodiment with reference to the accompanying drawing.

Specific embodiment

Referring to Fig.1, Fig. 2, Fig. 3, the utility model one kind not four sword right angle milling cutter of equal part, including knife handle 1 and cutter head 2, institute It states cutter head to set there are four the blade that is centrosymmetric, two in four blades is across the long tooth blades of center line 1 4, other two is the short tooth blade 6 for not spanning across center line 25, and described two long tooth blades are centrosymmetric, described two short Serrated knife sword is centrosymmetric, and described two long tooth blades, which all have, is located in the middle long straight line blade 7 and length positioned at edge is straight Angle blade 8, described two short tooth blades, which all have, is located in the middle short straight line blade 9 and the short right angle blade 10 positioned at edge. Two long tooth blades and two short tooth blades form not equal segmentation flute profile design, can effectively prevent and avoid the production of cutter work in-process Raw vibration.

Preferred scheme is equipped with short more between the knife spine of described two long tooth blades and the cutting edge of adjacent short tooth blade The body formed bottom of the tooth 11 in face, is equipped with long polyhedron between the knife spine of described two short tooth blades and the cutting edge of adjacent long tooth blade Molding gear bottom 12 forms long and short polyhedron molding gear Bottom Shape, and chip space is bigger, can more rapidly shunt iron filings, be not likely to produce Built-up edge.The large space type moulding arranging of downward spiral is equipped between the knife spine of four blades and the cutting edge of adjacent blade It considers slot 13 to be worth doing, to cooperate long and short polyhedron molding gear bottom to carry out effective quick chip removal, can more rapidly shunt iron filings, be not easy to produce Raw built-up edge.The utility model is to reduce not waiting for vibration to divide tooth Shape Design, and dissipating power face has more chip spaces, i.e., more Big polyhedron molding gear Bottom Shape has the molding chip space groove design that can increase intensity and be easier to chip removal.

In addition, the utility model is not limited to above embodiment, as long as it reaches this reality with essentially identical means With novel technical effect, the protection scope of the utility model all should belong to.
