Description
Technical field
The utility model relates to a kind of blade, specifically is a kind of annular seal groove highly-efficient processing cutter.
Background technology
The narrow seal groove of common plain cutter processing end face annular of available technology adopting, on universal significance, this cutter relatively is fit to milling plane, generally uses in to the Milling Process of conventional hydronalium.As shown in Figure 1, be the schematic configuration diagram of prior art plain cutter commonly used, because the processing of annular seal groove, cutter is worked completely cutting under the state, machining condition is not good, so efficient can not significantly promote.
But such profile cutter has following defective: because the field that the utility model is used is the narrow groove of ring packing, cutter is completely cut and is unfavorable under the state that heat distributes smoothly, and heat dispersion descends, and cutting data can not be bigger.Therefore cause the cutting time to increase, the cutter most of the time is the grinding state, thereby tool wear increases.Because material processed is a cast magnesium alloy, after cutter is by blunt, cause frictional force to strengthen, caloric value increases severely, in case heat is elevated to burning-point, easy breaking out of fire hidden danger.
Therefore,, how to improve the very important problem of cutting scheme, will improve heat-sinking capability especially, improve the sharp of cutting edge for narrow seal groove processing.If only change the blade angle of cutter, make blade sharper, at short notice, radiating effect can guarantee really, but surface quality still can not be comparatively satisfied, mainly contains following two point defects:
Defective 1: owing to be milling, cutter is subjected to the influence of interrupted cut power, and Tool in Cutting is completely cuts, and feed rate is received restriction to a certain extent.For two blade milling cutters, the time that always has half processes in idle running.And because the milling cutter that provides of each producer all can provide a cutting data table, cutting rate has ceiling restriction, can not unrestrictedly improve process velocity.Therefore, in conjunction with above-mentioned, be restricted to a certain extent with milling cutter efficient.
Defective 2:, fundamentally do not solve the problem of surface quality of workpieces though original cutter has been made improvement through the milling cutter tool of grinding.The first, though the cutter tooth of milling cutter is to be interrupted cutting, the working time is short, and cool time is long in air, but the milling cutter that diameter is less, the chip removal sword degree of depth is also very shallow, the eliminating that is unfavorable for excising thing, heat accumulates gradually, causes the generation of built-up edge, and machined material has the trend of extension; The second, the cutter of employing is right-hand cutter normally, and the end tooth of right-hand cutter is a positive rake angle, cutting edge is sharp, machining condition good, but the cutting direction of side edge makes progress perpendicular to workpiece, and the burr that easily produces on the workpiece seamed edge is many.
Can see that by top analysis for the processing of annular seal groove class part, existing cutter can't be finished processing tasks, the difficulty of chip removal simultaneously, working (machining) efficiency is on the low side, and disaster hidden-trouble is arranged.In a word, need a kind of efficient cutter of taking into account efficient and surface quality that can fundamentally solve in the production badly and change this present situation.
Do not have at present explanation or the report of discovery, do not collect both at home and abroad similarly data as yet yet with the utility model similar techniques.
The utility model content
On the low side and not good these problems of surface quality for the chip removal difficulty, the working (machining) efficiency that solve cutter in the above-mentioned prior art, the purpose of this utility model is to provide a kind of annular seal groove highly-efficient processing cutter, has solved chip removal in the narrow seal groove process of end face annular, efficient, surface quality problems.
In order to reach above-mentioned utility model purpose, a kind of annular seal groove highly-efficient processing blade described in the utility model comprises: blade base, the protruding sword of blade, the protruding sword of blade is arranged on a side of blade base.
Described blade base, it is shaped as quadrangle or more than the polygon on four limits.
The protruding sword of described blade, its cutting edge are flat, fillet or other regular shapes.
Prior art plain cutter commonly used is because the processing of annular seal groove, and cutter is worked completely cutting under the state, and machining condition is not good, so efficient can not significantly promote.Easily produce more side flange burr and bottom thread shape tool marks in addition in the reality, suface processing quality is relatively poor.
Have bottom thread shape tool marks, analyzing has two: one, and the process of milling is an interrupted cut process, and mechanical shock that cutter tooth is subjected to and variations in temperature are very big.Mechanical shock makes cutting force that fluctuation be arranged, and causes vibration easily; The 2nd, because the error that milling cutter exists at aspects such as making installation be difficult to guarantee each cutter tooth of milling cutter on same circumference or end face, so milling always is in vibration and jiggly duty.In sum, what we adopted is traditional milling cutter such as tooth pitch such as grade, because each cutter tooth amount of feeding is identical, each cutter tooth Milling Force waveform is identical, cause that easily system of processing produces resonance, produced the spiral tool marks of regular shape, make the surface quality of workpieces that processes bad.
In addition, there is side flange burr, analysis has two: one, though the cutter tooth of milling cutter is to be interrupted cutting, the working time is short, and cool time is long in air, but the milling cutter that diameter is less, the chip removal sword degree of depth is also very shallow, the eliminating that is unfavorable for excising thing, and heat accumulates gradually, cause the generation of built-up edge, machined material has the trend of extension; The 2nd, the cutter that adopts is right-hand cutter normally, and the end tooth of right-hand cutter is a positive rake angle, cutting edge is sharp, machining condition good, but the cutting direction of side edge makes progress perpendicular to workpiece, and the burr that easily produces on the workpiece seamed edge is many.So, the generation of side flange burr and the accumulation of cutting heat, and select for use the hand of spiral of cutter that certain relation is arranged.
By above analysis, be not difficult to find out that the method for utilizing milling processes narrow seal groove, be to be difficult to realize for the surface quality of bottom of improving seal groove simultaneously and side.For this reason, the utility model has solved above-mentioned several problem by the change of structure, is a kind of process tool that can obtain satisfactory to both parties effect.
