Abstract

The utility model relates to a one-step molding drill tool which is a solid carbide drill tool. The one-step molding drill tool is characterized by comprising a molding part, chipping discharging grooves and a cutter bar, and further comprising a machine clamping handle. The cutter bar is connected with the molding part and the machine clamping handle, the chipping discharging grooves are distributed on the cutter bar in rank, and the upper end of the chipping discharging groove extends to the molding part. The one-step molding drill tool is capable of finishing two processes of hole drilling molding and hole boring molding in one step and meeting requirements of different drilling holes, the depth of the boring hole, and the external molding step according to the depth that the molding part of the molding drill tool enters into a workpiece. Without the need of the two processes, the one-step molding drill tool is convenient to use, and improves the operating accuracy and working efficiency and reduces the production cost.

Description

Cutter is bored in one-shot forming

Technical field

The utility model relates to a kind of cutter, particularly a kind of once boring, bore hole molding cutter.

Background technology

This cutter be generally to a kind of worker's parts hole, a kind of cutter of bore hole processing and forming.The process more complicated of these worker's parts will be passed through a plurality of steps such as boring, bore hole, generally adopts machining; Hole earlier with drill bit, after with borer worker's parts are carried out the bore hole moulding again, whole machining process process operation is many; Process is complicated; Production time is long, and homework precision and production efficiency are low, and production cost is high.

The purpose of the utility model solves the problems of the prior art exactly; A kind of disposable boring, bore hole molding cutter are proposed, can disposable completion boring and bore hole moulding two procedures, and can bore the depth that the cutter moulding section gets into worker's parts according to moulding and satisfy different boring, boring depth and the requirement of outside moulding step; Do not need two procedures; Easy to use, improved homework precision and operating efficiency, reduced production cost.

The utility model content

The technical problem that the utility model will solve; It is the deficiency that overcomes prior art; A kind of improved boring, bore hole one time forming cutting tool are provided, can bore the requirement that the depth that the cutter moulding section gets into worker's parts satisfies different borings, boring depth and step moulding according to moulding.For solving the problems of the technologies described above, the technical scheme of the utility model is: the utility model provides a kind of one-shot forming to bore cutter, is solid carbide; It is characterized in that; Comprise moulding section, chip area and knife bar, also comprise the machine clamp holder, said knife bar connects moulding section and machine clamp holder; Said chip area is arranged on the knife bar, and the upper end extends to moulding section.

Further, said moulding section and knife bar are the CVD coated carbides.

Further, said knife bar and machine clamp holder are cylindric straight rod type.

Further, said cutter rake face and back knife face intersection are mutually the cutting edge of 120 degree for width 1mm.

Further, said tool orthogonal rake is 85 degree, and relief angle is 20 degree.

Further, said chip area groove face, one side is the vertical cut face, one side is an arc surface, totally three, is evenly distributed at interval.

Further; Said moulding section has boring, bore hole one-shot forming function; Said moulding section first half is boring, borer part; Latter half is a step molding cutter part, and bore hole and worker's parts outer steps forming process are accomplished in moulding section boring simultaneously, and said chip area is used for discharging the disintegrating slag that boring, bore hole forming process produce.

The specific embodiment

Be depicted as the utility model one-shot forming like Fig. 1-3 and bore the tool structures sketch map; Comprise moulding section 1, chip area 2 and knife bar 3, also comprise machine clamp holder 4, said knife bar 3 connects moulding section 1 and machine clamp holder 4; Said chip area 2 is arranged on the knife bar 3, and the upper end extends to moulding section 1.

Further, said moulding section 1 is the CVD coated carbides with knife bar 3.

Further, said knife bar 3 is cylindric straight rod type with machine clamp holder 4.

Further, said cutter rake face and back knife face intersection are mutually the cutting edge 5 of 120 degree for width 1mm.

Further, said tool orthogonal rake is 85 degree, and relief angle is 20 degree.

Further, said chip area 2 groove faces, one side is the vertical cut face, one side is an arc surface, totally three, is evenly distributed at interval.

Further; Said moulding section 1 has boring, bore hole one-shot forming function; Said moulding section 1 first half is boring, borer part; Latter half is a step molding cutter part, and bore hole and worker's parts outer steps forming process are accomplished in moulding section 1 boring simultaneously, and said chip area 2 is used for discharging the disintegrating slag that boring, bore hole forming process produce.

Worker's parts to be processed are added man-hour; Machine clamp holder 4 one ends that at first cutter bored in one-shot forming are installed on the turning attachment; With this cutter of power set is the rotatable work of pushing ahead, and 1 pair of worker's parts of moulding section location drilling carries out bore hole and outer workpiece step forming process to drilling bore hole simultaneously.The utility model can bore the requirement that the depth that the cutter moulding section gets into worker's parts satisfies different borings, boring depth and step moulding according to moulding.
