Embodiment Construction

[0011] As shown in the figure, the two-edged chamfering knife includes a cutter head 1 and a handle 2. The cutter head 1 is arranged on the front section of the handle 2. The two cutting edges 3 on the mounting part, the cutting edge 3 is arranged on the outside of the mounting part, the cutter head 1 is conical, and there is a chip removal groove 4 between the mounting parts, the taper of the cutter head 1 is 28°, and the cutter head 1 is provided with vent holes 5 on the upper side, and the vent holes 5 communicate with the upper surface of the knife handle 2. On the side surface of the knife handle 2, there are several circular holes 6 communicated with the vent holes 5, which will generate a large amount of heat when the tool is working. , the heat on the cutter head 1 can be dissipated through the vent hole 5 on the cutter head 1, which improves the service life of the chamfering knife and reduces the wear caused by overheating. There is an opening, the opening is provide...

Abstract

The invention relates to the field of tool equipment, in particular to a double-blade chamber cutter. The double-blade chamber cutter comprises a cutter head and a cutter handle. The cutter head is arranged on the front section of the cutter handle. The cutter head and the cutter handle are integrally formed. The double-blade chamber cutter is characterized in that the cutter head comprises two cutting edge mounting parts arranged on the cutter head; cutting edges are arranged on the outer sides of the cutting edge mounting parts; the cutter head is conical; a chip groove is formed between the mounting parts; the upper side face of the cutter head is provided with vent holes communicated with the upper surface of the cutter handle; the side surface of the cutter handle is provided with a plurality of round holes communicated with the vent holes; the middle portion of the cutter handle is provided with a cavity; one side of the cavity is provided with an opening, a circular-arc-shaped protrusion is arranged at the opening, and the inner side of the circular-arc-shaped protrusion is arranged in the cutter handle; the inner side edge of the circular-arc-shaped protrusion is connected with the inner surface of an inner cavity of the cutter handle through a spring; the circular-arc-shaped protrusion is provided with a cutting edge. The double-blade chamber cutter is good in heat dissipation effect and capable of removing burrs.

Description

technical field [0001] The invention relates to the field of cutting tool equipment, in particular to a two-edged chamfering knife. Background technique [0002] In tool processing, chamfering knives are often used, which will generate a lot of heat and burrs during chamfering.
