Abstract
The utility model relates to a clip-on carbide cylindric milling cutter used in the metal cutting processing. The outer surface of the cutter body is provided with a plurality of columns of straight grooves which have a certain angle with the shaft line. Each groove is provided with a blade, a plurality of cutter heads and wedge blocks. The wedge blocks press the cutter heads and the blade by the screws. Each column of the cutter head is positioned on the blade to form a spiral surface, and the cutter heads are successively staggered a certain distance along the shaft direction and are arranged alternately. The four angles of the knife-edge of the cutter heads are grinded into the circular arc shape, and the four edges are straight lines. The spiral angle of the spiral surface composed of each column of the cutter head is 15-20 DEG C. The utility model has the advantages of high precision, long service life, large processing speed and small unit cutting power.
Description
The utility model belongs to the machine holding carbide alloy cylindrical milling cutter of metal cutting manufacture field.
As known in the art, in metal cutting processing, end mill(ing) cutter has been extensive use of carbide alloy.But the cylindrical milling cutter of using often in milling is because carbide alloy exists weakness such as fragility sharpening difference, so the overwhelming majority still uses high speed steel material to make." the milling technology data " that May nineteen eighty-three, West Germany Wa Erte cutter and grinding tool company published, reported be used for, the roughing carbide alloy cylindrical milling cutter of light duty machine, a plurality of independently carbide bits of this milling cutter are divided into ordered series of numbers and arrange spirally on the cylindrical knife external surface, every row cutter head has certain intervals each other, and cutter head is fastened on the cutter hub with cam pin.The appearance of this carbide alloy cylindrical milling cutter has overcome people and has thought that for a long time hard alloy cutter fragility is big, can not be used for the technology prejudice of cylindrical milling cutter, has opened up new road for cylindrical milling cutter adopts new material.
But, existing this class milling cutter, its cutter head all are that direct clamping is on end mill body, because the installation locating surface machining accuracy of cutter head is difficult for reaching higher requirement, therefore, the comprehensive positioning accuracy of cutter head on cutter hub is lower, can only be applicable to the roughing operation, in addition, with regard to carbide bit, shape has two kinds, and a kind of is square, and another kind is cup-shaped.The former, cutting edge is a straight line and parallel with machined surface, produces bigger radial load during the cutting of this cutter head, causes vibration easily and makes the cutter head tipping; The latter, its cutting edge is a circular arc, though radial cutting force is littler than straight line sword during cutting, still has certain vibration.Therefore, known this class cylindrical milling cutter has only minor diameter, be applicable in, the product of light duty machine, and only be suitable for carrying out roughing.
Task of the present utility model during to be that design is a kind of both be fit to, light duty machine also are fit to high-power lathe; Both be fit to carry out roughing, also be fit to accurately machined machine holding carbide alloy cylindrical milling cutter.
Machine holding carbide alloy cylindrical milling cutter of the present utility model, on the cylindrical knife external surface, have ordered series of numbers and axis straight-line groove at an angle, all be mounted with many group blade, cutter head and voussoirs in every row groove, each cutter head compresses, locatees the formation helicoid by screw and voussoir on respective blade.This clamping structure of cutter head on cutter hub compared with the cutter head clamping of known this class milling cutter, has big, the comprehensive positioning accuracy height of thrust, advantage that the cutter machining accuracy is high.In addition, it is circular arc that the cutter head sharpening of the utility model cylindrical milling cutter becomes four angles, and four limits are straight line.After the circular arc portion of this blade can make each cutter head cutting, the surface smoothness that its track forms on workpiece was higher; The straight flange cutting edge has increased major and minor drift angle, has reduced radial cutting force and main cutting force.Compare with the simple linear or the simple circular arc blade of known this series hard alloy cylindrical milling cutter, have the advantage that processing is highly polished, radial cutting force is little, the unit cutting power is little, vibration is little, cutting depth is big, cutter life is long.
Accompanying drawing 1 has been described an embodiment of the present utility model, and Fig. 1 (a) is the front view of present embodiment cylindrical milling cutter, and Fig. 1 (b) is a side cutaway view.
Shown in Fig. 1 (a), on cylindrical cutter body (1) outer surface, have ten row and axis straight-line groove at an angle; Shown in Fig. 1 (b), all be mounted with a blade (5), nine cutter heads (4) and nine voussoirs (2) in each row groove.Each cutter head (4) is gone up in respective blade (5) and is compressed, locatees the formation helicoid by screw and voussoir.It is circular arc that cutter head (4) sharpening becomes four angles, and four limits are straight line.Each is listed as the corresponding cutter head certain distance that staggers vertically successively, is staggered, and the helical angle of the helicoid that each row cutter head is lined up is 15～20 °.Present embodiment cylindrical milling cutter diameter is 150 millimeters, and width is 166 millimeters.
In Milling Processes, rotation along with cylindrical milling cutter, the every row at first cutter head of contact workpiece cut at first, each cutter head that is arranged in thereafter enters cutting operation successively, cylindrical milling cutter rotates a circle, just mill out a level and smooth straight line on the workpiece, along with the feed motion of cutter or workpiece, just mill out plane or curved surface. The machining condition of each cutter head is similar to the end mill blade on the milling cutter. Because the cylindrical cutter body diameter maximum of the utility model milling cutter can reach 180 millimeters, the cutter head quantity that can settle is big, so Milling Speed and productivity ratio are all very high. The utility model cylindrical milling cutter is used for CNC milling machine processing curve periphery, and effect is more outstanding.
Claims (3)
1, metal cutting processing machine holding carbide alloy cylindrical milling cutter, a plurality of independently carbide chips (5) mark is listed on cylindrical cutter body (1) outer surface and arranges spirally, every row blade (5) has certain intervals each other, blade (5) is fastened on the cutter hub (1) with screw (3), and feature of the present utility model is
On cylindrical cutter body (1) outer surface, have ordered series of numbers and axis straight-line groove at an angle, in order to installation blade (5) and cutter head (4),
