Abstract
The utility model provides an unequal-diameter end mill so as to overcome the shortcomings that when an existing end mill is used for machining a workpiece, the existing end mill is poor in machining performance, short in service life of a cutting tool, low in production efficiency, incapable of meeting machining requirements. The unequal-diameter end mill comprises a blade part (1), a neck part (5) and a handle part (4), wherein the a neck part (5) is smaller than the blade part (1) in diameter, the neck part (5) comprises a neck part I (2) and a neck part II (3), the neck part I (2), close to the blade part (1), is smaller than the neck part II (3) in diameter. The unequal-diameter end mill has the advantages of being good in machining performance, long in service life, high in production efficiency, and capable of meeting technological requirements of valve bonnet machining.
Description
Technical field
The utility model relates to a kind of milling cutter, especially relates to a kind of not isometrical slotting cutter.
Background technology
Milling cutter is made of blade, neck and shank, and shank is applicable to milling end face, inclined-plane, groove and step surface etc. by two kinds of staight shank and taper shanks.Existing slotting cutter is club shaped structure, and the diameter dimension of blade and neck equates.Slotting cutter has been applied to each industrial circle as a kind of cutting element, and as in the petroleum machinery processing industry, valve bonnet is the parts on the oil well pump, has 3 valve bonnets on each pump barrel at least.According to designing requirement, need to mill out 4 grooves at inwall on each valve bonnet, there is certain distance at the position of groove apart from end face, mill the diameter at position greater than the end face inner bore diameter.In the prior art, the recess diameter of slotting cutter is identical with the diameter of blade, because diameter is thick, length length can't reach the position of milling, needs are manually lacked milling cutter blade mill, neck is levigate when milling groove; So not only destroy the milling cutter original structure, the pad of welding position is ground off, reduced the intensity of cutter, simultaneously that blade and neck is levigate, require a great deal of time, production efficiency is low, when processing work, existing slotting cutter can not satisfy the processing request of valve bonnet.
The utility model content
In order to overcome existing slotting cutter when the processing work, poor processability, cutter life is short, the deficiency that production efficiency is low, can not satisfy processing request, the utility model provides a kind of not isometrical slotting cutter.
The technical scheme that its technical problem that solves the utility model adopts is: not isometrical slotting cutter, comprise blade, neck, shank, and recess diameter is less than diameter at edge part.Neck comprises neck I and neck II, and the neck I diameter of close blade is less than the diameter of neck II.
The beneficial effects of the utility model are, have good processability, long service life, and production efficiency is high, can satisfy the requirement of workpiece processing technology.
Description of drawings
Fig. 1 is the not isometrical end mill structure schematic diagram of the utility model.
Among the figure: 1. blade, 2. neck I, 3. neck II, 4. shank, 5. neck.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.But what those skilled in the art should know is to the invention is not restricted to the listed specific embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
The not isometrical slotting cutter of the utility model comprises blade 1, neck 5, shank 4, and the diameter of neck 5 is less than the diameter of blade 1.Neck 5 has neck I 2 and neck II 3 two parts at least, and neck I 2 diameters of close blade 1 are less than neck II 3 diameters near shank 4.
The not isometrical slotting cutter of the utility model has good processability, and the characteristics that production efficiency is high are compared with standard cutter, and prolong 50% the cutter life after the improvement, and production efficiency improves 2 times.This cutter is applicable to process on the inwall of workpiece, apart from the end certain distance is arranged, and the interior hole dimension of machined surface is greater than the internal diameter size of end.
It should be noted that above-described embodiment is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiments and not break away from the claim scope of this patent.
Claims (2)
1. not isometrical slotting cutter comprises blade, neck, shank, it is characterized in that: neck (5) diameter is less than blade (1) diameter.
2. described not isometrical slotting cutter according to claim 1, it is characterized in that: described neck (5) comprises neck I(2) and neck II (3), near the neck I(2 of blade (1)) diameter is less than the diameter of neck II (3).
