Abstract
The problem of present invention is burrs outside welded pipe process tool, solves existing cutter single-blade and the full wafer service life is shorter, installation inconvenience, stability is poor.Blade is positive hexagonal piece, its front and back is symmetrical, centre bore is coaxial with boss, and boss periphery is the identical sphere of radius, i.e. rake face, its six sides are the identical arc surface of radius, knife face after i.e., rake face, rear knife face intersection are the identical arc-shaped cutting edge of 12 radiuses, and the anterior angle of the cutting edge of blade is greater than or equal to 13 degree, blade is installed on cutter hub by screw, and limiter is fixed by screws on cutter hub.
Description
Technical field
The present invention is related with the outer burr removal cutter of straight seam high frequency welding pipe.
Background technology
The 8 angle of throat pieces that the outer burr of existing straight seam high frequency welding pipe removes cutter are four cornual plates, its front is identical for radius
Sphere, i.e. rake face, its four sides are the identical arc surface of radius, i.e., rear knife face, both intersections are the identical circle of 8 radiuses
Curved edge, its single-blade and full wafer service life are shorter, installation inconvenience, and stability is poor.
The content of the invention
The object of the present invention is to provide a kind of single-blade and full wafer to last a long time, easy for installation, the outer hair of the good welded tube of stability
Pierce process tool.
What the present invention was realized in：
Burrs outside welded pipe process tool, blade 1 are positive hexagonal piece, its front and back is symmetrical, is all that centre bore and boss are coaxial,
Boss periphery is the identical sphere of radius, i.e. rake face, its six sides are the identical arc surface of radius, i.e., rear knife face, preceding knife
Face, rear knife face intersection are the identical arc-shaped cutting edge of 12 radiuses, and the anterior angle of the cutting edge of blade 1 is greater than or equal to 13 degree, blade 1
Cutter hub 5 is installed on by screw 2, limiter 4 is fixed on cutter hub by screw 3, and limiter is moved with the axial groove on cutter hub matches somebody with somebody
Close, screw 3 is located in the axial groove 6 of limiter 4, and the confined planes of limiter 4 coordinate with a side of blade 1.
Limiter 4 and the axial groove 7 of cutter hub 5 coordinate.
Blade rake face of the present invention is interior concave spherical surface, which is the sphere of a radii fixus on regular hexagon blade
Ask obtained by difference；The blade can process cutting edge circular arc of different sizes to meet that the burrs outside welded pipe of different tube diameters is processed at the same time；
Further, since the blade is two-sided cutting edge, Gu relief angle is zero, this requires blade hook angle is sufficiently large, to be done on cutter hub
Go out and relief angle is installed, application claims blade hook angle is more than 13 degree, connects cutting edge center and rake face terminal is in alignment, measure
Anterior angle is 13 degree at straight line, since rake face is interior concave spherical surface, Gu blade true rake is more than 13 degree.Blade is fixed by screw
On cutter hub, in order to meet the clamping stability of different circular arc blades, limited block front and rear can be adjusted on cutter hub in a certain range
It is whole, until limited block front end contacts stabilization with circumference of blade arc surface, then limited block is fixed on cutter hub with screw.This hair
Bright single-blade and full wafer last a long time, easy for installation, and stability is good
In order to verify present invention actual use performance, tested in enterprise's all-the-way tracking of a professional production straight seam high frequency welding pipe,
This experiment mainly contrasts 4 sword blades by the 6 angle of throat pieces of applicant, 8 angle of throat piece of import and 12 angle of throat piece of product of the present invention
Very little, cost performance deficiency, does not include this experiment to mouth quantity.Result of the test such as table 1：
1 Tool in Cutting result of the test of table
It can be seen that life of product of the present invention is 2.67 times of 6 angle of throat pieces from 1 result of the test of table, be 2 times of 8 angle of throat piece of import；
The single-blade service life is 1.33 times of 6 angle of throat pieces and 8 angle of throat pieces.
In conclusion the present invention possesses the performance of brilliance and the cost performance of superelevation.

Embodiment
Burrs outside welded pipe process tool, blade 1 are positive hexagonal piece, its front and back is symmetrical, are all centre bores positive six
On the boss of angle, positive hexagonal boss periphery is the identical sphere of radius, i.e. rake face, its six sides are the identical circular arc of radius
Face, i.e., rear knife face, rake face, rear knife face intersection are the identical arc-shaped cutting edge of 12 radiuses, and the anterior angle of the cutting edge of blade 1 is more than
Or equal to 13 degree, blade 1 is installed on cutter hub 5 by screw 2, limiter 4 is fixed on cutter hub by screw 3, limiter and knife
Axial groove on body moves cooperation, and screw 3 is located in the axial groove 6 of limiter 4, the confined planes of limiter 4 and a side of blade 1
Face coordinates.Limiter 4 and the axial groove 7 of cutter hub 5 coordinate.
Carbide cutter tool slice processing method：Refering to Fig. 2, Fig. 2 is blade front view and left view, and shape is regular hexagon,
Can be by being machined into the blades of different circular arc Rs；Cutter head body schematic diagram refers to Fig. 3, and blade and limited block pass through spiral shell respectively
Nail is fixed on cutter hub, and limited block can adjust on cutter hub in a certain range；Refering to Fig. 3, limited block front end processes segment
Circular arc（It is slightly less than blade minimum circular arc R）, make to contact between limited block and blade more firm（Refer to Fig. 6）.
