Problems solved by technology

[0002] In tool processing, chamfering knives are often used, which will generate a lot of heat during chamfering, which will reduce the service life of the tool and increase the wear of the tool head. During processing, the gap between the tool and the clamping device There will be resonance between them, and the resonance will affect the machining accuracy of the tool

Embodiment Construction

[0011] As shown in the figure, the four-edged chamfering knife includes a cutter head 1 and a handle 2. The cutter head 1 is set at the front end of the handle 2. The cutter head 1 and the handle 2 are integrally formed. The four cutting edge installation parts on the upper part, the cutting edge 3 is set on the outside of the installation part, the cutter head 1 is conical, and there is a chip removal groove 4 between the installation parts. The taper of the cutter head 1 is 28°, which is convenient for chamfering and convenient The tool is chamfered or processed with a taper hole. The upper side of the cutter head 1 is provided with a vent hole 5. The vent hole 5 communicates with the upper surface of the handle 2. The side surface of the handle 2 is provided with a vent hole 5. The round hole will generate a lot of heat when the cutter is working. The heat on the cutter head can be dissipated through the vent hole 5 on the cutter head 1, which improves the service life of th...

Abstract

The invention relates to the field of cutter machining, in particular to a four-edge chamfering cutter. The four-edge chamfering cutter comprises a cutter bit and a cutter handle. The cutter bit is arranged at the front end of the cutter handle, and the cutter bit and the cutter handle are integrally formed. The four-edge chamfering cutter is characterized in that the cutter bit comprises four cutting edge installation parts arranged on the cutter bit, cutting edges are arranged on the outer sides of the installation parts, the cutter bit is in a taper shape, chip removal grooves are formed between the installation parts, the taper of the cutter bit is 28 degrees, the upper side face of the cutter bit is provided with vent holes communicated with the upper surface of the cutter handle, circular holes communicated with the vent holes are formed in the side surface of the cutter handle, a plurality of grooves are formed in the upper end of the cutter handle, circular-arc-shaped protrusions are arranged in the grooves, and the bottom ends of the protrusions are connected with the bottoms of the grooves through springs. The four-edge chamfering cutter is good in heat dissipating effect and clamping effect and capable of reducing resonance produced when the cutter works.

Description

technical field [0001] The invention relates to the field of tool processing, in particular to a four-edged chamfering tool. Background technique [0002] In tool processing, chamfering knives are often used, which will generate a lot of heat during chamfering, which will reduce the service life of the tool and increase the wear of the tool head. During processing, the gap between the tool and the clamping device There will be resonance between them, and the resonance will affect the machining accuracy of the tool. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention provides a four-edged chamfering knife with good heat dissipation effect, good clamping effect, and can reduce the resonance generated when the cutting tool is working. [0004] The technical scheme that solves the above-mentioned technical problem is as follows: [0005] The four-edged chamfering knife includes a cutter he...
