A Practical Carbide Knife

Abstract

The invention discloses a practical hard alloy cutter. The practical hard alloy cutter comprises a top plate. A key shaft is arranged on the inner wall of the top plate; the outer wall of the key shaft is connected to the inner wall of the top plate; a power supply is arranged on the right side of the key shaft; the outer wall of the power supply is connected to the inner wall of the top plate; and a wire is arranged on the inner wall of the power supply. According to the practical hard alloy cutter disclosed by the invention, by matching the top plate, a bottom plate, an upper plate and a bottom plate, the top plate, the bottom plate, the upper plate and the bottom plate form a closed space under the action of an impeller to wrap parts inside in the formed closed space, so that the innerparts are more stably connected to prevent the processing precision from being affected when the impeller rotates. The top plate and the upper plate are more compactly connected by means of an adhesive tape which seals the gap between the top plate and the upper plate to prevent foreign matters from entering, so that the defect that a conventional practical hard alloy cutter is poor in sealing property and stability is overcome, the production cost is saved for enterprises, and the practical hard alloy cutter is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a practical hard alloy knife. Background technique [0002] There are many shapes of milling cutters, for ordinary milling machines and CNC milling machines to process grooves and linear contours, and for milling and boring machining centers to process cavities, cores, curved surface shapes, and contours. Now more milling cutters are used for hole processing and cavity processing , in general, during processing, it is necessary to perform rough machining first, then change the milling cutter for semi-finishing, and then change the milling cutter for finishing. This process can achieve the goal. Such a process requires frequent replacement of the milling cutter, and the work is cumbersome.

[0002] There are many shapes of milling cutters, for ordinary milling machines and CNC milling machines to process grooves and linear contours, and for milling and boring machining centers to process cavities, cores, curved surface shapes, and contours. Now more milling cutters are used for hole processing and cavity processing , in general, during processing, it is necessary to perform rough machining first, then change the milling cutter for semi-finishing, and then change the milling cutter for finishing. This process can achieve the goal. Such a process requires frequent replacement of the milling cutter, and the work is cumbersome. Low efficiency, especially in the processing and use of computer casings, due to the needs of its special shape, even if a combination of different common tools can not meet the processing requirements, and the common tool is a single head, scrapped after the service life is completed, the utilization rate is low High, in the prior art, for example, the invention patent with application number 201310465840.0 includes a cutter head and a handle, the cutter head is fixed at the end of the handle, the cutter head includes a first-order cutter head and a second-order cutter head, and the first-order cutter head is fixed On the second-stage cutter head, a scissors-shaped tapered edge is provided on the end surface of the first-stage cutter head, a chamfered edge and a first-order auxiliary edge are provided on the peripheral surface of the first-stage cutter head, and a There is a wave cutting edge, and the wave cutting edge is provided with two wave crest structures. Although the invention is simple in structure, there are many deficiencies and defects. In the existing equipment, the design of the wave cutting edge has defects, and the wave cutting edge has a Teeth are prone to breakage during milling and the blade has fallen off during turning milling. The positioning accuracy is low when a smooth straight shank or tapered shank is used for positioning. There is often a certain gap between the shank and the fixture, and the fixation is not firm. Vibration often occurs, which affects the precision of machining. For these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a practical hard alloy knife to overcome the defects in the prior art
