Abstract
The present invention is burrs outside welded pipe process tool, solves existing cutter single-blade and the full wafer service life is shorter, installation is inconvenient, the problem of stability difference.Blade is positive hexagonal piece, its front and back is symmetrical, centre bore is coaxial with boss, and boss periphery is the identical spherical surface of radius, i.e. rake face, its six sides are the identical arc surface of radius, that is flank, rake face, flank 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 mounted 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 technique
8 angle of throat pieces of the outer burr removal cutter of existing straight seam high frequency welding pipe are four cornual plates, and front is that radius is identical
Spherical surface, i.e. rake face, four sides are the identical arc surface of radius, i.e. flank, and the two intersection is the identical circle of 8 radiuses
Curved edge, single-blade and full wafer service life are shorter, and installation is inconvenient, and stability is poor.
Summary of the invention
The object of the present invention is to provide a kind of single-blades and full wafer to last a long time, easy for installation, the outer hair of the good welded tube of stability
Pierce process tool.
The present invention is implemented as follows:
Burrs outside welded pipe process tool, blade 1 are positive hexagonal piece, and front and back is symmetrical, is all centre bore and boss
Coaxially, boss periphery is the identical spherical surface of radius, i.e. rake face, and six sides are the identical arc surface of radius, i.e. flank,
Rake face, flank 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 is mounted on cutter hub 5 by screw 2, and limiter 4 is fixed on cutter hub by screw 3, the axial groove on limiter and cutter hub
Dynamic cooperation, screw 3 are located in the axial groove 6 of limiter 4, and the confined planes of limiter 4 and a side of blade 1 cooperate.
The axial groove 7 of limiter 4 and cutter hub 5 cooperates.
Blade rake face of the present invention is interior concave spherical surface, which is the sphere of a radii fixus on regular hexagon blade
It asks obtained by difference；The blade can be processed cutting edge circular arc of different sizes to meet the burrs outside welded pipe processing of different tube diameters simultaneously；
Further, since the blade is two-sided cutting edge, Gu relief angle is zero, it is sufficiently large that this requires blade hook angles, to do on cutter hub
Relief angle is installed out, the present invention claims blade hook angles to be greater 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 greater 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 can front and back tune in a certain range on cutter hub
It is whole, limited block is fixed on cutter hub until limited block front end and circumference of blade circular arc face contact stabilization, then 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, in enterprise's all-the-way tracking examination of a professional production straight seam high frequency welding pipe
It tests, this test mainly compares 4 angle of throat pieces 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
Cutting edge quantity is very little, and cost performance is insufficient, is not included in this test.Test result such as table 1:
1 Tool in Cutting test result of table
It can be seen that the product of the present invention service life is 2.67 times of 6 angle of throat pieces from 1 test result of table, be the 2 of 8 angle of throat piece of import
Times；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 cost performance of brilliant service performance and superelevation.

Specific embodiment
Burrs outside welded pipe process tool, blade 1 are positive hexagonal piece, and front and back is symmetrical, is all centre bore positive six
On the boss of angle, positive hexagonal boss periphery is the identical spherical surface of radius, i.e. rake face, and six sides are the identical circular arc of radius
Face, i.e. flank, rake face, flank 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 it is equal to 13 degree, blade 1 is mounted on cutter hub 5 by screw 2, and limiter 4 is fixed on cutter hub by screw 3, limiter and knife
The dynamic cooperation of axial groove on body, screw 3 are located in the axial groove 6 of limiter 4, the confined planes of limiter 4 and a side of blade 1
Face cooperation.The axial groove 7 of limiter 4 and cutter hub 5 cooperates.
Carbide cutter tool slice processing method: referring to Fig.2, Fig. 2 is blade main view and left view, shape is regular hexagon,
It can be by being machined into the blades of different circular arc Rs；Cutter head body schematic diagram passes through spiral shell refering to Fig. 3, blade and limited block respectively
Nail is fixed on cutter hub, and limited block can adjust in a certain range on cutter hub；Refering to Fig. 3, limited block front end processes segment
Circular arc (is slightly less than blade minimum circular arc R), makes to contact stronger (being detailed in Fig. 6) between limited block and blade.
