Abstract
The utility model discloses a large-knifing roughing-feed rotatable milling cutter. The large-knifing roughing-feed rotatable milling cutter comprises a rotatable cutter body and a plurality of rotatable milling blades, a plurality of chip removing grooves are distributed in the rotatable cutter body in the circumferential direction, a blade positioning groove is formed inside each chip removing groove, the rotatable milling blades are installed inside the blade positioning grooves, two adjacent circumferential rotatable milling blades are installed in a staggered mode, and edge lengths of cutting edges of the bottoms of the two adjacent circumferential rotatable milling blades are connected. The large-knifing roughing-feed rotatable milling cutter has the advantages of being simple in structure, higher in cutting efficiency and wider in application range.
Description
Technical field
The utility model relates to a kind of machining tool, relates in particular to large cutting-in roughing feed indexable milling cutter.
Background technology
In the international market, roughing feed milling cutter has been used very general, is applied to the machining industry such as Die & Mould Market and automobile industry, and the characteristics of this cutter maximum can realize roughing feed processing exactly, thereby realizes improving working (machining) efficiency.The feed engagement of roughing feed milling cutter, can reach at present the 3mm left and right, with respect to traditional face milling cutters, can improve tens times, but simultaneously he is that to sacrifice cutting-in be cost, because the design principle of roughing feed milling cutter, exactly blade bottom cutting edge and cutterhead bottom surface are arranged to certain angle, the axially loaded when radial force during by the plain cutter feeding changes the roughing feed milling cutter feeding into, thereby realize large amount of feeding processing, so roughing feed milling cutter mainly relies on the bottom cutting edge to be cut, its cutting-in is restricted, current general roughing feed milling cutter, cutting depth is in the 1.5mm left and right, the 3mm that can reach far below conventional facing cut cutter is 7 ~ 8mm even.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, stock-removing efficiency is higher, range of application is wider large cutting-in roughing feed indexable milling cutter is provided.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of large cutting-in roughing feed indexable milling cutter, comprise rotation cutter hub and a plurality of Indexable milling insert, described rotation cutter hub is along circumferentially being distributed with a plurality of chip areas, be provided with a blade locating slot in each chip area, described Indexable milling insert is installed in the blade locating slot, circumferential two adjacent Indexable milling insert arranged in dislocation, and the sword appearance of the bottom cutting edge of two Indexable milling inserts connects.
Described circumferentially two adjacent Indexable milling inserts, unequal with respect to the height of the cutterhead bottom surface that rotates cutter hub, unequal with respect to the distance of the rotary middle spindle that rotates cutter hub.
Described Indexable milling insert is m with respect to cutterhead bottom surface angulation, 10 °≤m≤11 °.
Compared with prior art, the utility model has the advantage of:
Large cutting-in roughing feed indexable milling cutter of the present utility model, circumferential two adjacent Indexable milling insert arranged in dislocation, and the sword appearance of the bottom cutting edge of two Indexable milling inserts connects, arrange arranging of Indexable milling insert by appropriate design on the rotation cutter hub, the sword appearance of adjacent two Indexable milling inserts of arranged in dislocation is connect, make the whole working depth of indexable milling cutter be doubled, in the characteristics that retain original roughing feed milling cutter, increased the cutting-in of roughing feed milling cutter, thereby realize roughing feed, the highly-efficient processing of large cutting-in, widened the range of application of roughing feed milling cutter.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model indexable milling cutter.
Fig. 2 is the structural representation of transposition milling cutting insert arranged in dislocation in the utility model.
Fig. 3 is the front view of transposition milling cutting insert in the utility model.
Fig. 4 is the A-A cutaway view of Fig. 3.
In figure, each label means:
1, rotation cutter hub; 2, Indexable milling insert; 11, chip area; 12, blade locating slot; 13, cutterhead bottom surface; 14, rotary middle spindle; 21, bottom cutting edge.
The specific embodiment
Fig. 1 to Fig. 4 shows a kind of large cutting-in roughing feed indexable milling cutter embodiment of the present utility model, this indexable milling cutter comprises rotation cutter hub 1 and a plurality of Indexable milling insert 2, rotation cutter hub 1 is along circumferentially being distributed with a plurality of chip areas 11, be provided with a blade locating slot 12 in each chip area 11, Indexable milling insert 2 is installed in blade locating slot 12, circumferential two adjacent Indexable milling insert 2 arranged in dislocation, and the sword appearance of the bottom cutting edge 21 of two Indexable milling inserts 2 connects, arrange arranging of Indexable milling insert 2 by appropriate design on rotation cutter hub 1, the sword appearance of adjacent two Indexable milling inserts 2 of arranged in dislocation is connect, make the whole working depth of indexable milling cutter be doubled, in the characteristics that retain original roughing feed milling cutter, increased the cutting-in of roughing feed milling cutter, thereby realize roughing feed, the highly-efficient processing of large cutting-in, widened the range of application of roughing feed milling cutter.
Circumferential two adjacent Indexable milling inserts 2, height with respect to the cutterhead bottom surface 13 that rotates cutter hub 1 is unequal, distance with respect to the rotary middle spindle 14 of rotation cutter hub 1 is unequal, is convenient to like this to control that the sword of bottom cutting edge 21 of two adjacent Indexable milling inserts 2 is long spatially forms and join.Indexable milling insert 2 is m with respect to cutterhead bottom surface 13 angulations, 10 °≤m≤11 °.
In the present embodiment, the diameter of rotation cutter hub 1 is 160mm, cutting tip 2 is the facing cutter blade, the long L of blade, wide S, L=S=12.7mm, blade thickness is h, h=4.76mm, Indexable milling insert 2 is with respect to 10 ° of cutterhead bottom surface 13 angulation m values, the axial height of last Indexable milling insert 2 is H1, its securing member center is D1 to the distance of the rotary middle spindle 14 of rotation cutter hub 1, the axial height of a rear Indexable milling insert 2 is H2, its securing member center is D2 to the distance of the rotary middle spindle 14 of rotation cutter hub 1, H1=7.7mm, H2=6.2mm, D1=154mm, D2=140mm, like this in cutting process, the long spatially formation of sword that has just realized the bottom cutting edge 21 of two adjacent Indexable milling inserts 2 is joined.
Although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model.Any those of ordinary skill in the art, in the situation that do not break away from the technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
