Description

Three-edge graver

Technical Field

The utility model belongs to the technical field of the technique of engraver cutter and specifically relates to a three sword carving tools.

Background

The special engraving cutter used on the numerical control engraving cutter usually achieves the engraving purpose by rotating a cutting material through a cutter point, at present, diamond is the material with the highest hardness in materials found in the nature, the hardness of the diamond is higher than that of materials such as artificially synthesized hard alloy, the adhesive force between the diamond and nonferrous metal and nonmetal materials is small, when the diamond is applied to cutting machining, scraps are not easy to adhere on the cutter point, and the diamond is one of the best cutter materials.

The structure of the welding position of the existing diamond tool bit and the alloy tool bar is too simple, the welding surface is only a single surface, the welding area is small, the problems of desoldering and the like easily occur, the structure of the welding position is too complex, the problems of desoldering and the like can be avoided, but the requirement on the welding process of the diamond tool bit and the alloy tool bar is higher, and the cost is increased.

Disclosure of Invention

To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a three sword carving tools.

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

the utility model provides a three sword carving tool, includes cutter arbor and tool bit, the one end of cutter arbor is provided with erects groove and two grip blocks, two be formed with between the grip block with erect the groove and link up mutually the grip block, erect the groove with the grip block constitutes the sword groove, the tool bit is fixed in the sword inslot, the tank bottom in sword groove is an inclined plane, and is corresponding the tool bit bottom surface also is the inclined plane, the inclined plane in sword groove with the inclined plane phase-match of tool bit, the tool bit top sets up the three cutting edge that is the annular array and distributes, the cutting edge all is higher than the notch in sword groove.

Further, the cross sections of the cutter head and the cutter groove are in a T shape.

Furthermore, an included angle between the inclined surface and a plane in which the cutter bar extends is an acute angle or an obtuse angle.

Further, the cutter head and the cutter bar are fixed through welding.

Further, the material of the cutter bar is tungsten steel alloy.

Furthermore, the material of tool bit is diamond.

Adopt above-mentioned scheme, the beneficial effects of the utility model reside in that: this product sets up the effect that the centre gripping groove played the fixed tool bit of centre gripping on the cutter arbor, cooperates the inclination on inclined plane for the cutter bit can form the centre gripping with the cutter arbor and erect multiple fixed mode, has ensured fixed knot structure's stability, and the structure of cutter arbor and cutter bit fixed department is comparatively simple, can ensure the firmness and the bonding of face of weld again, and the fixed technology degree of difficulty when avoiding too complicated structure increase cutter bit and cutter arbor to weld.

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 three-edge graver comprises a knife bar 1 and a knife head 2, wherein one end of the knife bar 1 is provided with an erection groove 3 and two clamping blocks 4, a clamping groove 5 communicated with the erection groove 3 is formed between the two clamping blocks 4, the erection groove 3 and the clamping groove 5 form a knife groove, the knife head 2 is fixed in the knife groove, the bottom of the knife groove is an inclined surface 6, the bottom surface of the knife head correspondingly is also the inclined surface 6, the inclined surface 6 of the knife groove is matched with the inclined surface 6 of the knife head, three cutting edges 7 distributed in an annular array are arranged at the top of the knife head 2, and the cutting edges 7 are higher than the notch of the knife groove. The three cutting edges 7 are all made of diamond,

further, the cross sections of the tool bit 2 and the tool grooves are in T shapes.

Further, an included angle between the inclined surface 6 and a plane in which the extension direction of the cutter bar 1 is located is an acute angle or an obtuse angle. Inclined plane 6 with the contained angle between the plane of cutter arbor 1 extending direction place is a non-right angle of inclination, when cutting the work piece through the rotation, inclined plane 6 itself provides the certain holding power of tool bit 2, the shape that combines the cross section all is tool bit 2 and the sword groove of "T" font, tool bit 2 and the sword groove of "T" font become the state of erectting, be difficult for deviating from for structure after tool bit 2 and the fixed equipment of cutter arbor 1 is more stable, more firm, when cutting the work piece through the rotation, the wear-resisting of three sword carving tool that this product and current tungsten steel carbide made, the durability is better, be favorable to prolonging its life-span.

Further, the cutter head 2 and the cutter bar 1 are fixed by welding. The contact surface of the cutter head 2 and the cutter bar 2 is a welding surface.

Further, the material of the cutter bar 1 is tungsten steel alloy.

Further, the material of the tool bit 2 is diamond.

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.
