Abstract

The utility model provides a multiple-edge carving tool, include the cutter arbor and set up in the tool bit of cutter arbor one end, be provided with the cramping body that a plurality of is the distribution of annular array on the tool bit, be formed with the mounting groove between two adjacent cramping bodies, it has the blade to inlay in the mounting groove, and the notch of mounting groove is surpassed on the top of blade, and the blade is the pyramid form. The product has the advantages that the blade is embedded in the mounting groove through the mounting groove formed between the clamping bodies, so that the embedding surface and the welding area of the blade are increased, stress points are uniformly distributed during machining and cutting, the firmness of the cutter is ensured, and the cutting frequency is increased, so that the vulnerability of the graver is reduced, and the collapse resistance, the wear resistance and the workpiece finish degree of the cutter are improved; this product is the pyramid form, and each edge of blade is a cutting edge that can carry out the cutting, has reduced the cutting resistance of carving tool during the multiple-blade cutting to promote the whole process velocity of carving tool, both saved work piece process time, can promote the finished product quality again.

Description

Multi-edge graver

Technical Field

The utility model belongs to the technical field of the special carving tool of numerical control engraver and specifically relates to a multiple-blade carving tool.

Background

Engraving is a traditional manual process, and the traditional engraving mainly depends on the skill level of an engraver, and has low production efficiency, high cost and poor repeatability. Therefore, people begin to use a numerical control engraving machine to produce engraving process finished products in batch and on a large scale in cooperation with an engraving knife.

The diamond has high hardness and can cut various materials, but the diamond material is also brittle, so the diamond cannot be used alone to manufacture a cutter, therefore, people can manufacture various cutting tools by compounding a blade made of the diamond on a cutter bar made of hard alloy, namely, a diamond carving tool which is a special cutter on a numerical control carving machine.

The diamond blade on the existing diamond carving knife is in a sheet shape and is welded with one side of a hard alloy cutter bar, the carving knife is used for welding only one side of the mosaic surface of the blade, the welding area is small, the carving knife is easy to desolder and collapse in the process of processing materials, the cutting edge of the carving knife can be used for only one edge or two edges of cutting materials, and the cutting resistance of the cutting edge is large during cutting.

Disclosure of Invention

To the deficiencies existing in the prior art, an object of the utility model is to provide a multi-blade graver.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a multiple-edge carving tool, include the cutter arbor and set up in the tool bit of cutter arbor one end, be provided with the clamping body that a plurality of is annular array and distributes on the tool bit, two are adjacent be formed with the mounting groove between the clamping body, it has the blade to inlay in the mounting groove, the top of blade is higher than the notch of mounting groove, the blade is the pyramid form.

Further, the tool bar is made of cemented carbide.

Further, the blade is made of diamond.

Further, the cutter arbor is the cylinder pole.

Adopt above-mentioned scheme, the beneficial effects of the utility model reside in that: the product is characterized in that the blade is embedded in the mounting groove formed between the clamping bodies, so that the embedding surface and the welding area of the blade are increased, the firmness and the desoldering property of the cutter are ensured, the blade is in a pyramid shape and is in a stable radial structure from the cutter point, stress points are uniformly distributed during processing and cutting, stress edges are smaller, and the cutting frequency is increased, so that the vulnerability of the carving knife is reduced, and the collapse resistance, the wear resistance and the workpiece finish degree of the cutter are improved; each edge that this product is pyramid form blade is a cutting edge that can carry out the cutting to realized that the multiple-cutting-edge is total to imitate the sword length, compared with traditional single-cutting-edge, twolip cutting, reduced the cutting resistance of carving tool during the multiple-cutting-edge cutting, thereby promoted the whole process velocity of carving tool, both saved work piece process time, can promote the off-the-shelf quality again, made the finished product that the sculpture obtained do work more meticulously.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1-6, a multi-blade graver comprises a knife bar 1 and a knife head 2 arranged at one end of the knife bar 1, wherein a plurality of clamping bodies 3 distributed in an annular array are arranged on the knife head 2, an installation groove 6 is formed between two adjacent clamping bodies 3, a blade 4 is embedded in the installation groove 6, the top end of the blade 4 is higher than the notch of the installation groove 6, and the blade 4 is in a pyramid shape. The blades 4 may be set to be triangular pyramid, quadrangular pyramid, pentagonal pyramid, hexagonal pyramid, etc. according to actual requirements, three blades 5 may be used for cutting when the blades are set to be triangular pyramid, and four blades 5 may be used for cutting when the blades are set to be quadrangular pyramid.

Further, the tool holder 1 is made of cemented carbide.

Further, the blade 4 is made of diamond.

Further, the tool bar 1 is a cylindrical bar.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
