Abstract
The utility model provides a multiple -cutting -edge mouth carving tool, including the base member cutter arbor tool grain terminal with locating the base member cutter arbor, specifically: the tip car of base member cutter arbor has the round platform, the side processing of round platform has four transition inclined planes, the surface machining of round platform is fluted, tool grain is fixed in through the mode of brazing the recess. The utility model discloses a multiple -cutting -edge mouth carving tool passes through the design of four blades of symmetry, because wearing and tearing are even relatively, the life of carving tool can increase, and machining efficiency and precision all can improve moreover.
Description
Technical field
The utility model relates to sintered carbide tools technical field, is specifically related to a kind of multiple-cutting-edge mouth graver.
Background technology
Engraved stone is as a kind of molding mode of Arts works, and the exquisiteness that its works are expressed and levels of precision have very high demand to engraving precision.Existing graver many employings single-blade for processing of stone designs, and not only working (machining) efficiency is low, and tool loss is fast; Or adopt multiple-cutting-edge design, but current many Cutting Edge Designs often structure relative complex, not only cost increases, and the probability that fault occurs continues to improve to a certain extent.
Utility model content
In view of this, the utility model provides a kind of multiple-cutting-edge mouth graver, under being intended to the prerequisite ensureing to carve precision, improves the stock-removing efficiency of graver further significantly.
The technical solution adopted in the utility model is specially:
A kind of multiple-cutting-edge mouth graver, comprise matrix knife bar and the cutter grain being located at matrix knife bar end, particularly: the end car of described matrix knife bar has round platform, the side of described round platform is processed with four intermediate incline, the Surface Machining of described round platform is fluted, and described cutter grain is fixed on described groove by brazing mode.
In above-mentioned multiple-cutting-edge mouth graver, described cutter grain comprises table top, cutting edge inclined-plane and cutting edge, particularly: described table top is outward extended with four cutting edge inclined-planes, what position was relative often organizes the both sides that cutting edge inclined-plane is symmetrically distributed in described table top, and the intersection on adjacent described cutting edge inclined-plane forms cutting edge.
In above-mentioned multiple-cutting-edge mouth graver, the position on each described cutting edge inclined-plane is corresponding with intermediate incline position described in one of them to be connected, and described cutting edge inclined-plane and the described intermediate incline of corresponding linking are coplanar.
In above-mentioned engraved stone process, the angle described in relative a group between cutting edge inclined-plane is defined as the cutting angle α of graver, and the span of described cutting angle α is 70 ~ 90 °, is preferably 80 °.
In above-mentioned engraved stone process, the width of described table top is 0.3 ~ 0.5mm, is preferably 0.4mm.
In above-mentioned multiple-cutting-edge mouth graver, described cutter grain is the lamination layer structure be made up of PCD layer and alloy-layer, and described PCD layer is exposed to outside described groove, and described alloy-layer is located within groove.
The beneficial effect that the utility model produces is:
Graver of the present utility model adopts the version of symmetrical multiple cutting edges, and asymmetric the causing avoided due to cutting edge in process occurs that cutting edge collapses the situations such as scarce, makes in engraving process comparatively mild, improves the precision of engraving; Loss due to each cutting edge is tending towards even, and the probability broken down reduces greatly, relatively extends the Acceptable life of cutter.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, more completely the utility model can be understood better.Accompanying drawing described herein is used to provide further understanding of the present utility model, and embodiment and explanation thereof, for explaining the utility model, are not formed improper restriction of the present utility model.

Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
A kind of multiple-cutting-edge mouth graver as Figure 1-4, comprise matrix knife bar 1 and the cutter grain 5 of carbide alloy, matrix knife bar 1 end car has round platform 2, the side of round platform 2 is processed with four intermediate incline 3, the Surface Machining fluted 4 of round platform 2, cutter grain 5 is fixed in groove 5 by brazing mode; Wherein, the structure of cutter grain 5 mainly comprises table top 6, cutting edge inclined-plane 7 and cutting edge 8, particularly:
Table top 6 stretches out and is processed with four cutting edge inclined-planes 7, relative one group of cutting edge inclined-plane 7, position is symmetrically distributed in the wherein both sides of table top 6, the intersection on adjacent cutting edge inclined-plane 7 is cutting edge 8, namely in the present embodiment, article four, cutting edge 8 is uniformly distributed in the circumference of table top 8, in order to ensure that the work of graver is feasible and reliable, corresponding cutting edge inclined-plane 7 and intermediate incline 3 must be coplanar.
Cutter grain 5 is the lamination layer structure be made up of PCD layer 51 and hard alloy layer 52, and PCD layer is wherein exposed to outside groove, and alloy-layer is then located within groove.In engraved stone process, the angle between one group of relative cutting edge inclined-plane 7 is defined as the cutting angle α of graver, and cutting angle α is 70 ~ 90 °, is preferably 80 °.In addition, the width b of table top 6 is 0.3 ~ 0.5mm, is preferably 0.4mm.
As mentioned above; embodiment of the present utility model is explained; obviously, as long as do not depart from fact inventive point of the present utility model and effect, will be readily apparent to persons skilled in the art distortion, is also all included within protection domain of the present utility model.
