Problems solved by technology
However, the common triangular pyramid knife currently used has a rake angle of 30°, so its knife tip is relatively blunt, and it is only suitable for processing metal materials such as steel and brass, but it is characterized by good strength and can be ground to a small size. Angled triangular pyramid knife, but because it is not sharp, it is not widely used

Embodiment Construction
[0014] The present invention is described below in conjunction with accompanying drawing.
[0015] attached figure 1 , 2 The deep-relief triangular pyramid knife according to the present invention includes a handle 1 and a tip 2, and the handle 1 and the tip 2 are integrally formed; wherein the tip 2 includes 3 side edges 3, and each side The included angles between the edge 3 and the remaining two side edges 3 are equal; the angle of the rake angle 4 in the knife tip is 12° to 16°.
[0016] Wherein the diameter of the bottom of the tip 2 is set at 6mm to 10mm, and the material of the triangular pyramid knife is set as tungsten carbide hard alloy steel.
[0017] The design of the deep-relief triangular pyramid knife of the present invention improves the rake angle 4 angles of its knife tip 2, so that the three side edges 3 of the triangular pyramid knife can reach the sharpness of the side edge of a tapered knife, making it suitable for use During the process, the three sid...

Abstract
The invention discloses a deep embossing triangular-pyramid tool, which comprises a tool shank and a tool nose, wherein the tool shank and the tool nose are molded integrally; the tool nose comprises three side blades, and each side blade forms equal included angles together with the other two side blades; a front angle in the tool nose is 12-16 degrees. In the deep embossing triangular-pyramid tool, the front angle of the tool nose is improved, the three side blades of the triangular-pyramid tool can reach the sharpness degree of each side blade of a taper tool, and the three side blades are used for cutting at the same time, thereby greatly increasing the sharpness degree and durability of the triangular-pyramid tool, and further reducing wear when the triangular-pyramid tool is used for machining deeply-embossed black bricks. Since jittering of the tool nose is small, the deep embossing triangular-pyramid tool is suitable for carving crisp materials. Meanwhile, the service life of the triangular-pyramid tool can be prolonged.
Description
technical field [0001] The invention relates to a cone cutter, in particular to a deep-relief triangular pyramid cutter. Background technique [0002] In recent years, with the rapid development of computer technology, computer-aided design and manufacturing and numerical control machining technology have become an important support for the development of manufacturing industry. At present, in the CNC brick carving, it is mainly used for the rough processing of some simple patterns and the production and processing of characters, such as the rough processing of brick carving, or even semi-finishing, and then the carving artist manually completes the fine carving, commonly known as "opening". Mutually". Correct the reasons: First, the bricks are uneven in material, have many pores, are large and brittle, which makes the bricks prone to chipping when engraved with traditional CNC tools; second, the finishing tools generally use sharper single-edged conical knives , due to th...
