Abstract
The utility model discloses a wave-edged finger type milling cutter with spiral relief-grinding teeth. A rear angle is designed as a spiral groove backoff structure, wave edges are arranged on the rear angle of the backoff, cutting edge is in spiral involute gear profile on the basis of the structure of the present spiral finger type milling cutter. The utility model is designed in reasonable structure, sharp-tooth rear angles of the original cutting tool are relief grinded into spiral groove backoff rear angles, so that the rear angles are the same after being divided equally on a circumference; wave edges are also shoveled and grinded, thereby after the cutting edges of the milling cutter is blunt, the front edge can be grinded with little change of gear forms, and the depth of a chip-holding groove, the cutting efficiency and the durable force will not be influenced. The cutting edge of the milling cutter is convenient to extend backward continuously to be trimmed, which is easy to be renewed and reused through being trimmed by the backoff after the cutting edge is used in utmost, so that the service life of the cutting tool is prolonged. As the cutting edge is designed into the involute gear profile, the gear forms and depth are processed as accurately as possible in one cutting during rough machining, the uniform allowance of the involute gear profile of the gear is guaranteed, thereby a basis is laid for the later high speed finish machining, and the production efficiency is improved.
Description
(1) technical field:
The utility model belongs to the cutting-tool engineering field, and what relate generally to is a kind of spiral relief grinding tooth waveform sword finger cutter.
(2) background technology:
The spiral finger cutter has one of rough machined main cutting tools for cutting of machining large-modulus gear.The deficiency of this milling cutter mainly contains the following aspects: 1, relief angle is a pointed tooth, and equal portions unanimity, just change greatly with blunt back sharpening rear edge face profile of tooth, very high to the teeth groove requirement, each sharpening is very big to the teeth groove influence, and mill is shallow more more, also shorten therefrom the service life of cutter, and the profile of tooth of processing is only limited to linearity, thereby allowance is big especially, fine finishining efficient after the influence; 2, smear metal is thin and big, is curl shape, and difficulty is cut by the row of causing.Because cutting force is big, the consistent non-resistance of axial cutting force direction causes instrument, cutter horizontal jitter, thereby influences working (machining) efficiency, tool life and workpiece surface roughness; 3, cutting edge is a straight line, is difficult to be processed into smart finger cutter, is exactly to process reluctantly, also can only use once, and profile accuracy has just lost, and generally can only be used to rough mill.
(3) summary of the invention:
The purpose of this utility model promptly produces thus, proposes a kind of spiral relief grinding tooth waveform sword finger cutter.Use this milling cutter can not only improve machining accuracy and production efficiency, and can prolong the service life of cutter and the scope of application of expansion cutter.
For achieving the above object, the utility model is achieved through the following technical solutions: it is on the architecture basics of existing spiral finger cutter, and relief angle is designed to corner structure behind the helicla flute back-off, and back-off is provided with the waveform cutter.
The utility model reasonable in design, simple in structure, because the pointed tooth relief angle relief grinding of its former cutter is a helicla flute back-off relief angle, one week of relief angle five equilibrium is all equated, and relief grinding has the waveform cutter, like this, in use, when the milling cutter cutting edge with can grinding lip surface after blunt, castellated shape changes little, capacity chip slot depth, stock-removing efficiency, durable power are unaffected, and required precision changes little.The milling cutter cutting edge is convenient to the finishing that constantly extends back, use the limit after, be easy to obtain renovation and reuse through back-off finishing, prolonged the service life of cutter.And its cutting edge is designed to involute profile, and one cutter puts profile of tooth and deep processing in place as far as possible when reaching roughing, guarantees the even allowance of involute profile of gear, for the high speed fine finishining in later stage lays the first stone, and then has improved production efficiency.Because the waveform sword of its setting can make smear metal divide into strips, chip removal is smooth, cutting force is little thereby make, and has changed the cutting force direction, and the stable cutting vibration is little, iron filings thickness and width size in the time of can controlling cutting.
(4) description of drawings:
The utility model has following accompanying drawing:
Accompanying drawing 1 is the structural representation of annular circular arc every the staggered ripple of tooth for the utility model waveform sword.
Accompanying drawing 2 is the structural representation of spiral arc ripple for the utility model waveform sword.
Accompanying drawing 3 is the structural representation of spiral sawtooth ripple for the utility model waveform sword.
Among the figure, 1-milling cutter, 2-waveform sword, 3-relief angle, 4-cutting edge.
(5) specific embodiment:
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure: present embodiment is on the architecture basics of existing spiral finger cutter, relief angle 3 is designed to the back-off relief angle, and one week of relief angle five equilibrium all equates, relief grinding has various waveform swords 2 on the back-off relief angle, every tooth staggered ripple (as shown in Figure 1), spiral arc ripple (shown in Figure 2) and spiral sawtooth ripple (shown in Figure 3), its effect is that smear metal is divided into strips as annular circular arc, and thickening diminishes, cutting force is reduced, select suitable ripple can make chip removal smooth.Cutting edge 4 is involute profile in the shape of a spiral, and its cutting edge can be designed to side set waveform sword, spiral waveform sword or negative helical teeth waveform sword according to the processing needs.The characteristics of side set waveform sword are side set cuttings, and that can cut is dark, stressed little, chip breaking is effective, last row and back one row's staggered cutting can the large tracts of land cuttings and do not squeeze iron filings, side edge also plays shear action, and cutting edge length is increased, and has improved the durability of cutter.The characteristics of spiral waveform sword are in use, rotation, feeding along with cutter, make every helix cutting edge cutting position form a row, and back toothrow advances to cut about 0.6-0.9 than front-seat tooth spiral, forms the thrust cutting naturally, adds the feed feeding, just become the cutting of both direction, it can make cutter more steady when cutting, and point of a knife is stressed very little, and chip removal is smooth.The characteristics of negative helical teeth waveform sword are that alloy blade is bonded in the cutter hub skewed slot with bonding agent, in use, are inwardly cut by the outermost end of gear, in the adaptation, the fine finishining of the hard flank of tooth, point of a knife intensity height, thus the precision of processed profile of tooth improved, improved productivity ratio simultaneously.
