Abstract
The invention discloses a kind of large cutting-in roughing feed indexable milling cutter, comprise and rotate cutter hub and multiple Indexable milling insert, described rotation cutter hub is circumferentially distributed with multiple chip area, a blade locating slot is provided with in each chip area, described Indexable milling insert is installed in blade locating slot, two Indexable milling insert arranged in dislocation that circumference is adjacent, and the sword appearance of the bottom cutting edge of two Indexable milling inserts connects.This large cutting-in roughing feed indexable milling cutter has the advantage that structure is simple, stock-removing efficiency is higher, range of application is wider.
Description
Technical field
The present invention relates to a kind of machining tool, particularly relate to large cutting-in roughing feed indexable milling cutter.
Background technology
In the international market, roughing feed milling cutter has used very general, is applied to the machining industry such as Die & Mould Market and automobile industry, and the maximum feature of this cutter can realize roughing feed processing exactly, thus realizes improving working (machining) efficiency.The feed engagement of roughing feed milling cutter, about 3mm can be reached at present, relative to traditional face milling cutters, tens times can be improved, but he sacrifices cutting-in for cost simultaneously, because the design principle of roughing feed milling cutter, exactly insert bottom cutting edge and cutterhead bottom surface are arranged to certain angle, radial force during plain cutter feeding is changed into axially loaded during roughing feed milling cutter feeding, thus realize large amount of feeding processing, so roughing feed milling cutter mainly relies on bottom cutting edge to cut, its cutting-in is restricted, roughing feed milling cutter general at present, cutting depth is at about 1.5mm, far below 3mm even 7 ~ 8mm that the facing cut cutter of routine can reach.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provides the large cutting-in roughing feed indexable milling cutter that a kind of structure is simple, stock-removing efficiency is higher, range of application is wider.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of large cutting-in roughing feed indexable milling cutter, comprise and rotate cutter hub and multiple Indexable milling insert, described rotation cutter hub is circumferentially distributed with multiple chip area, a blade locating slot is provided with in each chip area, described Indexable milling insert is installed in blade locating slot, two Indexable milling insert arranged in dislocation that circumference is adjacent, and the sword appearance of the bottom cutting edge of two Indexable milling inserts connects.
Two Indexable milling inserts that described circumference is adjacent, unequal relative to the height of the cutterhead bottom surface rotating cutter hub, unequal relative to the distance of the rotary middle spindle rotating cutter hub.
Described Indexable milling insert is m relative to cutterhead bottom surface angulation, 10 °≤m≤11 °.
Compared with prior art, the invention has the advantages that:
Large cutting-in roughing feed indexable milling cutter of the present invention, two Indexable milling insert arranged in dislocation that circumference is adjacent, and the sword appearance of the bottom cutting edge of two Indexable milling inserts connects, the arrangement of Indexable milling insert is arranged by appropriate design on rotation cutter hub, the sword appearance of adjacent two Indexable milling inserts of arranged in dislocation is connect, the overall processing degree of depth of indexable milling cutter is doubled, while the feature retaining original roughing feed milling cutter, increase the cutting-in of roughing feed milling cutter, thus realize roughing feed, the highly-efficient processing of large cutting-in, widen the range of application of roughing feed milling cutter.

Detailed description of the invention
Fig. 1 to Fig. 4 shows one of the present invention large cutting-in roughing feed indexable milling cutter embodiment, this indexable milling cutter comprises rotation cutter hub 1 and multiple Indexable milling insert 2, rotate cutter hub 1 and be circumferentially distributed with multiple chip area 11, a blade locating slot 12 is provided with in each chip area 11, Indexable milling insert 2 is installed in blade locating slot 12, two Indexable milling insert 2 arranged in dislocation that circumference is adjacent, and the sword appearance of the bottom cutting edge 21 of two Indexable milling inserts 2 connects, the arrangement of Indexable milling insert 2 is arranged by appropriate design on rotation cutter hub 1, the sword appearance of adjacent two Indexable milling inserts 2 of arranged in dislocation is connect, the overall processing degree of depth of indexable milling cutter is doubled, while the feature retaining original roughing feed milling cutter, increase the cutting-in of roughing feed milling cutter, thus realize roughing feed, the highly-efficient processing of large cutting-in, widen the range of application of roughing feed milling cutter.
Two Indexable milling inserts 2 that circumference is adjacent, unequal relative to the height of the cutterhead bottom surface 13 rotating cutter hub 1, unequal relative to the distance of the rotary middle spindle 14 rotating cutter hub 1, long spatially formation of sword being convenient to the bottom cutting edge 21 controlling two adjacent Indexable milling inserts 2 like this connects.Indexable milling insert 2 is m relative to cutterhead bottom surface 13 angulation, 10 °≤m≤11 °.
In the present embodiment, the diameter rotating cutter hub 1 is 160mm, cutting tip 2 is 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 relative to cutterhead bottom surface 13 angulation m value 10 °, the axial height of last Indexable milling insert 2 is H1, its retainer member central is D1 to the distance of the rotary middle spindle 14 rotating cutter hub 1, the axial height of a rear Indexable milling insert 2 is H2, its retainer member central is D2 to the distance of the rotary middle spindle 14 rotating cutter hub 1, H1=7.7mm, H2=6.2mm, D1=154mm, D2=140mm, like this in cutting process, long spatially formation of sword just achieving the bottom cutting edge 21 of two adjacent Indexable milling inserts 2 connects.
Although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention.Any those of ordinary skill in the art, when not departing from technical solution of the present invention scope, can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solution of the present invention, or being revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to the technology of the present invention essence to any simple modification made for any of the above embodiments, equivalent variations and modification, all should drop in the scope of technical solution of the present invention protection.
