Description

A kind of compound chamfers knife

Technical field

It the utility model is related to machining tool field, and in particular to a kind of compound chamfers knife.

Background technology

The common rose reamer of the prior art can only process chamfering, and dovetail knife of the prior art can only process lower chamfering, When some workpiece need to process upper two kinds of features of chamfering and lower chamfering, it is necessary to be carried out respectively using common rose reamer and dovetail knife The processing of one procedure, so that since tool changing operation expends the time so that production efficiency reduces；In addition, the process uses Number of cutters is more, causes the cost of charp tool higher.

The content of the invention

In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of compound chamfers knife, it can add successively Two kinds of features of chamfering and lower chamfering in work, without using two kinds of cutters, so as to remove from the time spent by tool changing, improve and add Work efficiency rate；Cutter usage quantity can also be reduced, reduces the cost of charp tool.

In order to solve the above-mentioned technical problem, technical solution is used by the utility model：

The utility model provides a kind of compound chamfers knife, including cutter head, and the cutter head side wall is at least provided with two cutters tooth, respectively Cutter tooth includes the first segment of cutting and the second segment of cutting, the end faces outwards of the radial contour edge of the first segment of cutting from the cutter head Tilt and extend to the side margins of the cutter head, the side margins of the radial contour edge of second segment of cutting from the cutter head Towards tilted extension.

Specifically, Transitional cut is equipped between the tail end of the first segment of cutting of same cutter tooth and the head end of the second segment of cutting Section, the radial contour of Transitional cut section are axially in parallel with the compound chamfers knife.

Specifically, the angle of the radial edges contour line of first segment of cutting and the central axis of the compound chamfers knife For a, 43 °≤a≤47 °.

Specifically, the angle of the radial edges contour line of second segment of cutting and the central axis of the compound chamfers knife For b, 43 °≤b≤47 °.

Specifically, the quantity of cutter tooth is two, and axial first relief angle of cutter tooth is c1,4 °≤c1≤6 °, the axial direction of cutter tooth Second relief angle is c2,7 °≤c2≤9 °.

Specifically, the quantity of cutter tooth is two, has chip pocket between two cutters tooth of cutter head head end, the chip pocket Circumferential angle is d, 45 °≤d≤50 °.

The beneficial effects of the utility model are：

For cutter head side wall at least provided with two cutters tooth, each cutter tooth includes the first segment of cutting and the second segment of cutting, the first cutting Section is used to process chamfering, and the second segment of cutting is used to process lower chamfering.I.e. the compound chamfers knife of the utility model can add successively Two kinds of features of chamfering and lower chamfering in work, without using two kinds of cutters, so as to remove from the time spent by tool changing, improve and add Work efficiency rate；Cutter usage quantity can also be reduced, reduces the cost of charp tool.

Embodiment

Further illustrate specific embodiment of the present utility model below in conjunction with the accompanying drawings.

See that such as 1 Fig. 2, compound chamfers knife provided by the utility model, including cutter head 1,1 side wall of cutter head is at least provided with two knives Tooth, each cutter tooth include the first segment of cutting 2 and the second segment of cutting 3, and the radial contour edge of the first segment of cutting 2 is from the end of cutter head 1 Portion extends to the side margins of cutter head 1 towards outer incline, the side margins court of the radial contour edge of the second segment of cutting 3 from cutter head 1 Tilted extension.

Specifically, transition is additionally provided between the tail end of the first segment of cutting 2 of same cutter tooth and the head end of the second segment of cutting 3 to cut Cut section 4, the radial contour of Transitional cut section 4 is axially in parallel with compound chamfers knife.

Specifically, Fig. 2 is seen, the radial profile of the first segment of cutting 2 and the angle of the central axis of compound chamfers knife are a, a =45 °.

Specifically, Fig. 2 is seen, the radial profile of the second segment of cutting 3 and the angle of the central axis of compound chamfers knife are b, b =45 °.

Specifically, Fig. 3 is seen, the quantity of cutter tooth is two, sees Fig. 4, and axial first relief angle of cutter tooth is c1, c1=5 °, knife Axial second relief angle of tooth is c2, c2=8 °.The structure causes cutter tooth wearability to strengthen, and improves cutter life；In addition, reduce Interference after cutter tooth between knife face and workpiece face to be processed；Furthermore so that cutter tooth is more sharp, so as to improve compound chamfers knife To the processing quality of workpiece surface, product surface is avoided to produce burr.See Fig. 5, have between two cutters tooth of the head end of cutter head 1 Chip pocket, the circumferential angle of chip pocket are d, d=48 °.

Above disclosed is only the preferred embodiment of the utility model, certainly cannot be new to limit this practicality with this The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and are covered Scope.
