Abstract
The utility model relates to a kind of left-handed single-edge spiral milling cutter edge structures, it includes a cutter head with cutting edge, the cutter head includes a reinforcement structure being arranged on the cutting edge, it extends a distance into L along the edge surface from the point of a knife of the cutter head, and the reinforcement structure has an extrados far from the edge surface, the thickness of the reinforcement structure is gradually increased to thickness H from the point of a knife of the cutter head, then is progressively smaller until its end.The utility model is by adding reinforcement structure in cutting edge, to increase the structural strength of cutting edge, effectively prevent milling cutter during cutting in the case where keeping cost, it quickly results in cutting edge notch, situations such as cutting edge is worn, improves the service life of milling cutter.
Description
Technical field
The utility model relates to a kind of automobile interior decoration milling cutter more particularly to a kind of left-handed single-edge spiral milling cutter edge structures.
Background technique
The edge structure of existing left-handed single-edge spiral milling cutter can as shown in Figure 1, this left-handed single-edge spiral milling cutter right
During automobile interior decoration PP is cut containing glass fiber material, since the structural strength of its cutting edge 1 ' is weaker, so as to cause cutting
After cutting certain modulus, it may appear that cutting edge notch, situations such as cutting edge is worn, and then influence service life and just of left-handed single-edge spiral milling cutter
It is often used.
Utility model content
In order to solve the above-mentioned problems of the prior art, the utility model is intended to provide a kind of left-handed single-edge spiral milling cutter
Edge structure, to promote the service life of left-handed single-edge spiral milling cutter.
A kind of left-handed single-edge spiral milling cutter edge structure described in the utility model comprising a cutter head with cutting edge,
The cutter head includes a reinforcement structure being arranged on the cutting edge, is extended from the point of a knife of the cutter head along the edge surface
A distance L, and the reinforcement structure has an extrados far from the edge surface, the thickness of the reinforcement structure is described in
The point of a knife of cutter head rises and is gradually increased to thickness H, then is progressively smaller until its end.
Above-mentioned left-handed single-edge spiral milling cutter edge structure, is made of the hard alloy containing cobalt.
In above-mentioned left-handed single-edge spiral milling cutter edge structure, the wedge angle angle [alpha] of the cutter head is 45 °.
In above-mentioned left-handed single-edge spiral milling cutter edge structure, the distance L is 1mm.
In above-mentioned left-handed single-edge spiral milling cutter edge structure, the thickness H is 0.2mm.
Due to use above-mentioned technical solution, the utility model by adding reinforcement structure in cutting edge, thus
In the case where keeping cost, the structural strength of cutting edge is increased, milling cutter is effectively prevented during cutting, quickly results in
Situations such as cutting edge notch, cutting edge are worn improves the service life of milling cutter.In addition, the utility model is also by using containing
There is the hard alloy of trace element cobalt to be made, to increase the stability of milling cutter.
Detailed description of the invention
Fig. 1 is the schematic cross-section of the edge structure of existing left-handed single-edge spiral milling cutter；
Fig. 2 is a kind of schematic cross-section of left-handed single-edge spiral milling cutter edge structure of the utility model.
Specific embodiment
With reference to the accompanying drawing, the preferred embodiment of the utility model is provided, and is described in detail.
As shown in Fig. 2, the utility model, i.e., a kind of left-handed single-edge spiral milling cutter edge structure, comprising: cutter head 1 and knife handle
(not shown), wherein the reinforcement structure 12 that cutter head 1 has cutting edge 11 and is arranged on cutting edge 11, wherein
Reinforcement structure 12 extends a distance into L (in the present embodiment, distance L along 11 surface of cutting edge from the point of a knife O of cutter head 1
For 1mm), and the reinforcement structure 12 has the extrados 13 far from 11 surface of cutting edge, to make point of a knife O of its thickness from cutter head 1
It rises and is gradually increased to thickness H (in the present embodiment, thickness H is 0.2mm), then be progressively smaller until its end；In the present embodiment
In, the wedge angle angle [alpha] of the cutter head 1 with reinforcement structure 12 is 45 °.
The material of the edge structure of the utility model is the hard alloy containing trace element cobalt, for increasing cutter
Stability.
In conclusion the utility model carries out thickening processing to cutting edge 11 by using reinforcement structure 12, to enhance
The intensity of edge structure.After above-mentioned improvement, the utility model is in cutting process of the PP containing glass fiber material, relative to not tying
For the milling cutter that structure is reinforced, one times of life-span upgrading.
Above-described, the only preferred embodiment of the utility model is not intended to limit the scope of the utility model, this
Above-described embodiment of utility model can also make a variety of changes.It all claims according to the present utility model application and says
Simple, equivalent changes and modifications, fall within the claims of the utility model patent made by bright book content.This reality
What it is with novel not detailed description is routine techniques content.
