Abstract
The utility model belongs to the field of cutting tools and concretely relates to a forming milling cutter. The forming milling cutter comprises a shank, a cutter neck and a cutter bit, wherein two ends of the cutter neck are respectively connected with the shank and the cutter bit; the cutter bit comprises a first-stage cutter and a second-stage cutter; the first-stage cutter is provided with an end edge and a side edge; a first 60-DEG chamfer edge is arranged at the connection of the end edge and the side edge; and a second 20-DEG chamfer edge is arranged at the connection of the second-stage cutter and the first-stage cutter. The forming milling cutter has the advantages of simple and useful structure, capability of processing multi-stage slots through forming at one step, high efficiency and long service life.
Description
Technical field
The utility model belongs to the cutting tool field, specifically a kind of profile milling cutter.
Background technology
The structure of various cutters all is comprised of clamping part and working portion.Clamping part and the working portion of overall structure cutter all are made on the cutter hub; The working portion of inserted structure cutter (cutter tooth or blade) then is installed on the cutter hub.The clamping of cutter partly has with holes and band handle two classes.Rely on inner hole sleeve to be contained on the main shaft or axle of lathe with spot facing cutter, transmit torsional moment by axial bond or straight end-face key, such as cylindrical milling cutter, facing-type cutter etc.With the cutter of handle three kinds of rectangular shank, cylindrical handle and circular cone handles are arranged usually.Lathe tool, planing tool etc. are generally rectangular shank; The circular cone handle leans on the tapering bearing axial pushing force, and by the frictional force transmitting torque; Cylindrical handle generally is applicable to the cutters such as less fluted drill, slotting cutter, and the frictional force that produces when clamping during cutting is transmitted torsional moment.Much make with low-alloy steel with the shank of the cutter of handle, working portion then forms two parts butt welding with high-speed steel.The working portion of cutter is exactly the part that produces and process smear metal, comprises blade, makes smear metal structure, chip removal or appearance disconnected broken or that wind up store up the space of smear metal, the structural elements such as passage of cutting fluid.The working portion of the cutter that has is exactly cutting tip, such as lathe tool, planing tool, boring cutter and milling cutter etc.; The working portion of the cutter that has then comprises cutting tip and calibrated section, such as drill bit, reamer, reamer, inner surface broaching tool and screw tap etc.The effect of cutting tip is to excise smear metal with blade, and the effect of calibrated section is finished surface and the guiding cutter that smoothing has been cut.
Summary of the invention
The purpose of this utility model provides a kind of profile milling cutter for processing metal sheet material.
The utility model provides following technical scheme:
Profile milling cutter, it comprises handle of a knife and cutter neck, cutter head, cutter neck two ends connect respectively handle of a knife and cutter head, described cutter head comprises the first rank cutter and second-order cutter, the first rank cutter is provided with end sword and side edge, end sword and side edge junction are provided with 60 ° of first chamfering blades, and second-order cutter and cutter junction, the first rank are provided with 20 ° of second chamfering blades.
Described second-order cutter and cutter neck junction are provided with the 3rd chamfering blades and the 4th chamfering blades.
The utility model has the advantages that simple and practically, can one-shot forming process multistage groove, efficient is high, long service life.
