Abstract
The invention discloses a powerful drill bit for a cone. The powerful drill bit comprises a drill bit body. The drill bit body is of a chisel-edge corrected S-shaped structure. Cutting edges are arranged on the side end face of the drill bit body. A chip groove is formed between the cutting edges. The cutting edges and the chip groove are each in a spiral shape. The back taper ratio of the drill bit body is 0.25/100 mm. The core thickness ratio of the drill bit body is 30% of the cutter diameter. The slot back ratio of the drill bit body is 1.1/1. The helical angle of the drill bit body is 15 degrees. The main drill sharp angle of the drill bit body is 125 degrees. By means of the manner, the powerful drill bit can be suitable for machining the cone, through the special slot type and the large-taper design of the powerful drill bit, the surface smoothness of the cone is improved, the powerful drill bit is made of a German K40 wearproof material, multiple-time coping and reuse can be achieved, the environment protection property of a cutter is improved, high-rotation-speed high-feed machining can be achieved, and machining efficiency is improved.
Description
Technical field
The present invention relates to drill bit field, particularly relate to a kind of gear wheel Powerful drill.
Background technology
Present stage, the mode that recover petroleum mainly adopts deep-well to drill through, but oil exploitation majority is at lithosphere, therefore, very high with normal drill bit recover petroleum cost, and do not reach desirable formation depth.In this case, oil exploitation company is widely used rigidity life-span better rotary drill.
At present there is Kyocera in the drill bit producer of external processing gear wheel, Mitsubishi, the U.S. agree to receive, German Wa Er top grade, but due to foreign technology block and product price too high, cause the drill bit being applicable to processing gear wheel supporting less in oil exploitation industry.Mostly domestic rock bit of doing is to process with the drill bit of common process non-ferrous metal, this drill bit requires this mating holes except having that dimensional accuracy is high, surface roughness Ra is no more than 1.25, hole must not occur along features such as cones, difficulty of processing is very big, and the working (machining) efficiency of finish reaming after the modified rear brill that the past adopts, hinge, quenching is very low.
In order to reduce client's manufacturing cost, shortening the manufacturing cycle, design and manufactured a gear wheel Powerful drill.Its structure is applicable to HRC42-48 high-carbon steel and steel alloy; There is excellent borehole accuracy, times aperture, hole depth≤1.5, hole precision≤IT7, circularity≤0.005, surface roughness Ra≤1.2um.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of gear wheel Powerful drill, can be suitable for processing gear wheel, its special grooved and steep-taper design, improve the surface smoothness of gear wheel, and adopt German K40 high-abrasive material, repeatedly reconditioning recycling can be realized, improve the feature of environmental protection of cutter, high rotating speed height feeding processing can be realized, improve working (machining) efficiency.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of gear wheel Powerful drill, comprise drill body, described drill body adopts chisel edge correction S shape structure, described drill body side end face is provided with blade, chip area is offered between described blade, described blade and described chip area are all in the shape of a spiral, the back taper of described drill body is than being 0.25/100mm, the core thickness rate of described drill body is the tool diameter of 30%, the groove back of the body of described drill body is than being 1.1/1, the helical angle of described drill body is 15 °, the main drill point angle of described drill body is 125 °.
In a preferred embodiment of the present invention, the point of a knife R value of described drill body is 0.8.
In a preferred embodiment of the present invention, Helica coating has been carried out on described chip area surface.
In a preferred embodiment of the present invention, described drill body machining process route is Linear cut blanking, peripheral milling fine grinding figure paper size, tool grinder, the processing of CNC five travelling wheelhead roll grinder, passivation, inspection, clean and carve characters.
In a preferred embodiment of the present invention, described chip area is helical groove.
The invention has the beneficial effects as follows: present invention employs S type apex point, be suitable for processing gear wheel, its special grooved and steep-taper design, improve the surface smoothness of gear wheel, and adopt German K40 high-abrasive material, repeatedly reconditioning recycling can be realized, improve the feature of environmental protection of cutter.Based on above design, high rotating speed height feeding processing can be realized, improve working (machining) efficiency.Usefulness of the present invention is excellent groove groove design, and make bottom land openr, chip removal is more unobstructed, and hole wall is more smooth, improves the surface roughness of workpiece.The narrow land design of the large back taper of improvement, has and cuts the advantages such as sharp, hole surface quality is good, wearability is good, reduce cutting force and tool wear, add cutting-tool's used life.
