Abstract
The utility model belongs to the field of cutting tools, and particularly relates to a single-edged T-shaped cutter. The single-edged T-shaped cutter comprises a cutter handle and a cutter head. The cutter handle and the cutter head are integrally arranged or are arranged in a welded mode. One side of the cutter head is located on the same side with the other side of the cutter handle, and the other side of the cutter head protrudes out of the other side face of the cutter handle. Two circular arc angle cutting edges are arranged at a protruding end of the cutter head. A side cutting edge is arranged between the two circular arc angle cutting edges. The single-edged T-shaped cutter has the advantages that through the circular arc angle cutting edges and the side cutting edge which are arranged on the T-shaped cutter which is arranged in a unilateral mode, a groove mouth with a concave circular arc chamfering can be formed and machined once. The single-edged T-shaped cutter is simple in structure, highly efficiency in production and low in cost.
Description
Technical field
The utility model belongs to the cutting tool field, specifically the T-shaped cutter of a kind of single-blade.
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 T-shaped cutter of single-blade of a kind of processing metal sheet material or handicraft.
The utility model provides following technical scheme:
The T-shaped cutter of single-blade, it comprises handle of a knife and cutter head, handle of a knife and cutter head are integrated and arrange or the welding setting, described cutter head one side and handle of a knife another side one side, the cutter head opposite side is given prominence to the handle of a knife another side, the cutter head jag is provided with two arc chord angle cutting edges, is provided with the side cut sword between two arc chord angle cutting edges.
Described arc chord angle cutting edge place radius of a circle R is 1.6mm.
The utility model has the advantages that by the Circular Nose Cutting Edge on the T-shaped cutter of monolateral setting and side cut sword, the notch of energy one-shot forming processing belt concave arc chamfering, simple in structure, to produce efficiently, cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the T-shaped cutter of single-blade, it comprises handle of a knife 1 and cutter head 2, handle of a knife 1 is integrated with cutter head 2 and arranges or the welding setting, described cutter head 2 one sides and handle of a knife 1 one sides, cutter head 2 opposite sides are given prominence to handle of a knife 1 another side, and cutter head 2 jags are provided with between 3, two arc chord angle cutting edges 3 of two arc chord angle cutting edges and are provided with side cut sword 4.
Described arc chord angle cutting edge place radius of a circle R is 1.6mm.
