Abstract
The utility model relates to a processing cutting tool used for mechanical manufacturing, in particular to a finishing cutter of a breaking inner hole plate for a gas valve. The finishing cutter of the breaking inner hole plate for a processing valve, comprising a cutter holder; one end of the cutter holder is provided with a cutter head and a cutter body fixed on the cutter head; the front end of the cutter body is provided with a conical bit; the cutter nock of the cutter body is set; therefore, the cutting tool not only can be used for drilling, but also can be used for chamfering, and the cutter body is set into a flat shape. The structure of the finishing cutter can improve working efficiency, and also can prolong the service life of the cutting tool.
Description
Technical field
The utility model relates to a kind of machine-building process tool, is specifically related to a kind of gas valve smart cutter of orifice plate in the slubbing.
Background technology
In the machining, smear metal is difficult for getting rid of in working angles, smear metal is entangled with easily, the smear metal that existing cutter produces when cutting stops owing to being subjected to the cutter shaft end face, be not easy smooth eliminating, even paste on cutter hub because of high temperature, the heat radiation that seriously hinders cutter hub shortens the life-span of cutter hub, and the smear metal of pasting on cutter hub makes the surface of processing work produce scratch easily, can't make finished surface level and smooth.
The utility model content
At the problems referred to above, the purpose of the utility model pin provide a kind of can increase work efficiency and the gas valve of long service life with the smart cutter of orifice plate in the slubbing.
Gas valve smart cutter of orifice plate in the slubbing, comprise handle of a knife, handle of a knife one end has cutterhead and the cutter hub that is fixed on the cutterhead, the front end of cutter hub has taper bit, and described cutter hub cutter neck portion comprises straight endoporus blade, and straight endoporus blade upper end is provided with a circular arc sword, the circular arc sword other end is provided with interior chamfering blades, the interior chamfering blades other end is provided with the end face sword and the end face sword other end is provided with outer chamfering blades, and above-mentioned cutter hub is a flat, is beneficial to cutting and discharges.
The radius of described circular arc sword is 0.36～0.40mm.
The angle of chamfering blades and circular arc sword extended line is 30 ° in described, and described circular arc sword extended line is the extended line of the end that is connected with straight endoporus blade.
Described end face sword is 45 ° with the angle of outer chamfering blades.
Adopt such scheme, gas valve comprises handle of a knife with the smart cutter of orifice plate in the slubbing, and handle of a knife one end has cutterhead and the cutter hub that is fixed on the cutterhead, and the front end of cutter hub has taper bit, and described cutter hub is a flat.By the chamfering that to finish workpiece that is provided with at the utility model cutter hub upper slitter neck portion, once finish slubbing processing to workpiece, and cutter hub of the present utility model is a flat, the chip removal space that such structure provides is big, smear metal is easy to discharge from boring, can not cause the injury to finished surface, simultaneously because the chip removal space is bigger, also can improve the radiating effect of cutter hub, prolong the service life of cutter.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the enlarged drawing of A portion among Fig. 1;
Among the figure, 1, handle of a knife, 2, cutterhead, 3, cutter hub, 4, neck, 5, taper bit, 6, straight endoporus blade, 7, the circular arc sword, 8, interior chamfering blades, 9, the end face sword, 10, outer chamfering blades.
The specific embodiment
As depicted in figs. 1 and 2, the smart cutter of processing gas valve slubbing endoporus plate, comprise handle of a knife 1, handle of a knife 1 one ends have cutterhead 2 and the cutter hub 3 that is fixed on the cutterhead 2, the front end of cutter hub 3 has taper bit 5, also be provided with neck 4 on the described cutter hub, this neck 4 comprises the straight endoporus blade 6 on the cutter hub, the circular arc sword 7 that straight endoporus blade 6 upper ends are provided with, the interior chamfering blades 8 that circular arc sword 7 other ends are provided with, the radius of the outer chamfering blades 10. described circular arc swords 7 of the end face sword 9 of interior chamfering blades 8 other end settings and 9 other end settings of end face sword is that the angle of described interior chamfering blades 8 of 0.36～0.40mm. and circular arc sword 7 extended lines is 30 °, described circular arc sword 7 extended lines are the extended line of the end that is connected with straight endoporus blade 6. and described end face sword 9 is 45 ° with the angle of outer chamfering blades 10. and described cutter hub 3 is flat, is beneficial to the cutting discharge.
By sidewall keyway and U-lag are set at handle of a knife 1, the smart cutter of interior orifice plate is fixed on the knife rest, start the machine of the good workpiece of clamping, workpiece is processed, 5 pairs of workpiece of the taper bit of cutter are holed, because cutter hub 3 is a flat, the bits that get out are easy to flow out from the space of cutter hub and workpiece, smear metal is not easy to stockpile in the hole surface in the hole is not produced cut like this, because boring is better with the radiating effect of the big cutter hub like this in space of cutter hub, can prolong the service life of cutter.
