Abstract
The utility model belongs to the field of cutting knives, and particularly relates to a tungsten steel chamfering knife. The tungsten steel chamfering knife comprises a knife handle and a knife head which are connected or welded integrally, and chamfering edges are arranged on edges of the left end face and the right end face of the knife head. The tungsten steel chamfering knife has the advantages that a 45-degree chamfering groove can be machined in one step, the structure is simple and practical, production processes are few, and speed is fast.
Description
Technical field
The utility model belongs to the cutting tool field, specifically a kind of wolfram steel rose reamer.
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 the wolfram steel rose reamer of a kind of processing metal sheet material or handicraft.
The utility model provides following technical scheme:
The wolfram steel rose reamer, it comprises handle of a knife and cutter head, and handle of a knife is connected with the cutter head one or welds, and two end face edge are provided with chamfering blades about described cutter head.
The angle of described chamfering blades is 45 °.
The utility model has the advantages that 45 ° of chamfering grooves of one-shot forming processing, simple and practical, production process is few, and speed is fast.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the wolfram steel rose reamer, it comprises handle of a knife 1 and cutter head 2, and handle of a knife 1 is connected with cutter head 2 one or welds, and two end face edge are provided with chamfering blades 3 about described cutter head 2.
The angle of described chamfering blades 3 is 45 °.
