Background technology
Milling cutter, is the rotary cutter for Milling Process, with one or more cutters tooth.During work each cutter tooth successively between Cut the surplus of workpiece with having a rest.Milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece on milling machine Deng.
The traditional milling cutter mostly integral type now used, cutter head is as main working position, once damaging, then needs entirety more Change, adult is improved, while traditional milling cutter is due to hardness and bending strength problem, set more than its cutter head end using acute angle, and end Face is linear, and then reaches the purpose of reduction end impact, and to reach the purpose processed for a long time, but also generally existing is processed The problem of slow, with the optimization and progress of cutter head material, this phenomenon and to obtain essential improvement.
Utility model content
Regarding to the issue above, squeezed the utility model proposes one kind and cut milling cutter.
To solve above technical problem, the technical scheme that the utility model is provided is:
One kind is squeezed and cuts milling cutter, it is characterised in that including fix bar, connecting rod and cutter head, and the fix bar, connecting rod are one Body formula structure, fix bar is connected in cylinder, its one end with connecting rod, and the other end is provided with fixed block, and the fixed block is in rectangular The bodily form, the connecting rod in cylinder, its cylindrical periphery for being in provided with 4 chip areas, 4 chip areas in etc. Interval is circumferentially disposed, and chip area is elongated;
One end of the connecting rod is provided with contiguous block, and the contiguous block includes the first contiguous block and the second contiguous block, described First contiguous block and the second contiguous block are integral type structure, and the first contiguous block is hemispherical, and the second contiguous block is in cylinder, second The connecting plate on the periphery of contiguous block, the quantity of the connecting plate is multiple, and in circumferentially disposed at equal intervals, is set in the middle part of contiguous block There is connecting screw hole;
The cutter head includes blade, and cutter head is provided with connector and buckling groove, and the connector is located in the middle part of cutter head, described The size of buckling groove, shape are mutually agreed with contiguous block, and cutter head is connected by connecting screw, connector, connecting screw hole with contiguous block, The blade includes end sword and Zhou Ren, and the end sword is curved, and the section of the Zhou Ren is curved, and Zhou Ren relief angle is α, described α is -3 ° ± 1 °;
Further, the fix bar, connecting rod and the coaxial setting of cutter head;
Further, it is cylindrical straight that the hemispheric diameter that first contiguous block is in and the second contiguous block are in Footpath is identical;
Further, the length of the fix bar, connecting rod and cutter head is respectively L1, L2 and L3, the L1:L2:L3= 4.9:7.1:1。
The beneficial effects of the utility model are:
The utility model proposes one kind squeeze cut milling cutter, including fix bar, connecting rod and cutter head, fix bar and connecting rod are Integral mechanism, connecting rod is provided with chip area and contiguous block, and cutter head carries out goalpost positioning, and and connecting plate by contiguous block Clamping, is fixed finally by screw, uses wolfram steel to protrude design using arc for the end sword of the blade of material, the Zhou Ren of blade is also Using cambered design, different from existing cutting mill, of the present utility model squeeze cuts milling cutter construction simply, reasonable in design, cutter head It is demountable structure with connecting rod, is convenient for changing, and chip removal is quick, while hardness and bending strength are high, during work, first, end Portion extrudes workpiece, breaks ring work pieces process position, then to cutting, processing efficiency is higher, and cutting effect is also more preferable, while by Destroyed in Working position, the processing abrasion of milling cutter is also smaller, improves the service life of milling cutter, reduces processing cost.
