Abstract
The utility model belongs to the field of cutting knives, and particularly relates to a tungsten steel molding knife. The tungsten steel molding knife comprises a knife handle, a knife neck and a knife head, wherein two ends of the knife neck are respectively connected with the knife handle and the knife head, and the knife head is a three-step molding knife head with a first step cutting edge, a second step cutting edge and a third step cutting edge. The tungsten steel molding knife has the advantages that a three-step groove can be machined with the molding knife in one step, process is simple, and production cost is lowered.
Description
Technical field
The utility model belongs to the cutting tool field, specifically a kind of tungsten steel forming knife.
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 processing metal sheet material or the one-time formed tungsten steel forming knife of handicraft.
The utility model provides following technical scheme:
Tungsten steel forming knife, it comprises handle of a knife, cutter neck and cutter head, and cutter neck two ends connect respectively handle of a knife and cutter head, and described cutter head is the three rank moulding cutter heads that are provided with first step cutting edge, second step cutting edge, the 3rd step cutting edge.
The cutter neck edge of the junction of described cutter neck and cutter head is provided with chamfering.
The angle of described chamfering is 15 °.
The utility model has the advantages that operation is simple, reduces production costs by these forming cutter energy time processing three stepped recesses.
Description of drawings
Fig. 1 is structural representation of the present utility model.
