Abstract
The utility model relates to a cutting cone which belongs to the mechanical process field. The utility model is characterized in that the work part is provided with at least an annular groove with an angle to form a plurality of cutting cones, the work part of each section is ground into external circles with different diameters and unequal sizes to form a ladder shape, and then each cutting cone is ground to form corresponding back angles, forming a cutting edge. Therefore, the stratification micro cutting can be realized, the processing condition can be improved, the quality of products can be enhanced and the service life of the cutting cone can be prolonged.
Description
Affiliated technical field
The utility model relates to a kind of cutting cone that supplies machining to use.
Background technology
At present, the reamer of use is single awl sword, adds man-hour, and the chipping allowance once resecting that the object part is to be reamed reaches finished size.Like this,, and occur that bore area fineness behind the ream is poor, the seamed edge degree is big and quality problems such as size instability usually because the metal level of being stripped from is thicker, simultaneously, also since single awl sword to bear load big, quick abrasion, a thereby reconditioning is also short service life.
Summary of the invention
The purpose of this utility model provides a kind of raising product glossiness, reduces the seamed edge degree, dimensionally stable, the life-span and the modified cutting cone.
The purpose of this utility model is to realize like this, on the basis of known reamer structure, working portion is had at least the cannelure of one band angle, form a plurality of cutting cones, then, grind the cylindrical that each section diameter dimension does not wait respectively, outside diameter by the working portion front end is little, towards the shank direction, increases successively, the working portion outside diameter size of leaning on neck is then for to be deducted the reamer manufacturing tolerance by ream endoporus finished size higher limit, thereby make the cylindrical of the whole working portion of reamer constitute a stairstepping, then, each cutting cone is ground corresponding relief angle, form cutting edge, promptly become novel cutting cone.
The utility model is suitable for the ream processing of various structural steel parts and non-ferrous metal part through hole.This reamer under equal conditions compares with known reamer, has the following advantages: fraising quality height, and stable, practicality is wide, and long service life is made simply, and reconditioning is easy.
Description of drawings
Fig. 1 is a partial sectional view of the present utility model.
Fig. 2 is an A-A normal direction cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, among Fig. 1, the front end of shank (3) is provided with a neck (2), the front end of neck is working portion (1), work (1) part has cannelure (4) and (5) of two-track tape angle, form cutting cone (6) and (7), cutting cone (6), (7) become 30 to spend to 45 degree angles respectively with (8) with the reamer axis, and its optimum value is 35 degree.Working portion grinds into cylindrical (9), (10) and (11) that three diameter dimensions do not wait, cylindrical (9) is less than cylindrical (10), cylindrical (10) is less than cylindrical (11), and cylindrical (11) diameter dimension is then for to be deducted the reamer manufacturing tolerance by the finished size higher limit of ream endoporus.Among Fig. 2, each cutting cone is ground corresponding relief angle (12) respectively, its size is preferably in 6 degree between 8 degree.
Claims (1)
1, a kind of cutting cone, the front end of shank is provided with a neck, and the front end of neck is a working portion, it is characterized in that: working portion has the cannelure of one band angle at least, forms more than one cutting cone.
