Abstract
The utility model provides an engraving tool for reversely welding a PCD blade, which comprises a fixed cutter bar and a transition cutter bar arranged at one end of the fixed cutter bar, wherein one end of the transition cutter bar is provided with a supporting cutter bar; the fixed cutter bar, the transition cutter bar and the support cutter bar are coaxially arranged; a cutter groove is milled along the axial direction of the transition cutter bar and the support cutter bar, and the bottom surface of the cutter groove is superposed with the axial cross section of the transition cutter bar along the axial center line; the cutter groove is brazed with a PCD blade. According to the engraving tool for reversely welding the PCD blade, the welding surface is the largest surface of the cutter bar along the axial section, so that the welding area is largest, and the welding strength is highest. Simultaneously, when milling process sword groove, only need mill away half the cutter base member can, mill with among the prior art and fall more than half cutter arbor and compare, the cutter body volume of getting rid of is still less, and the cutter body intensity of sword groove department is better.
Description
Technical Field
The utility model relates to a superhard materials instrument field, especially an engraving tool of reverse welding PCD blade.
Background
The carving tool for welding the PCD blade comprises a tool bar, a tool groove and the PCD blade, wherein the bottom surface of the tool groove is a mounting surface for mounting the PCD blade, the upper surface of the PCD blade is a working surface, the working surface is brazed with the mounting surface, and the working surface is in the center of the tool. Because the working face has certain thickness again at the central PCD blade of cutter to need mill half cutter arbor material when processing the sword groove, just can satisfy the requirement, lead to the sword groove thickness thinner and welding face less, have in the use and weld, fall phenomenon such as piece, disconnected sword, thereby influence the result of use and the life-span of cutter.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough of prior art to a carving tool of anti-welding PCD blade is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a carving tool for reversely welding a PCD blade comprises a fixed tool bar and a transition tool bar arranged at one end of the fixed tool bar, wherein a supporting tool bar is arranged at one end of the transition tool bar; the fixed cutter bar, the transition cutter bar and the support cutter bar are coaxially arranged;
a cutter groove is milled along the axial direction of the transition cutter bar and the support cutter bar, and the bottom surface of the cutter groove is superposed with the axial cross section of the transition cutter bar along the axial center line; the cutter groove is brazed with a PCD blade.
Based on the above, the diameter of the transition cutter bar is smaller than that of the fixed cutter bar.
Based on the above, the diameter of the supporting knife rod is smaller than that of the transition knife rod.
Based on the above, the PCD blade includes tool bit, the fixed spacing portion of blade arc transition portion and blade, the width of tool bit is less than the width of the fixed spacing portion of blade, a side of tool bit with one side of the fixed spacing portion of blade coincide mutually, another side of tool bit with the other side of the fixed spacing portion of blade passes through the transition of blade arc transition portion and links up.
Compared with the prior art, the utility model has the advantages of substantive characteristics and progress, specifically speaking, the utility model provides an engraving cutter of anti-welding PCD blade is because the face of weld is the biggest face along axial cross-section of cutter arbor, and consequently, welding area is the biggest, and welding strength is the highest. Simultaneously, when milling process sword groove, only need mill away half cutter base member can, mill with among the prior art and fall more than half cutter arbor and compare, the cutter body volume of getting rid of is still less, and the cutter body intensity of sword groove department is better.

Detailed Description
Example 1
The present embodiment provides an engraving tool for reverse welding a PCD insert, which includes a stationary tool bar 1, and a transition tool bar 2 disposed at one end of the stationary tool bar 1, as shown in fig. 1, 2, 3 and 4. One end of the transition cutter bar 2 is provided with a supporting cutter bar 4; the fixed cutter bar 1, the transition cutter bar 2 and the supporting cutter bar 4 are coaxially arranged.
A cutter groove is milled along the axial direction of the transition cutter bar 2 and the support cutter bar 4, and the bottom surface of the cutter groove is coincided with the axial cross section of the transition cutter bar 2 along the axial center line; the tool slot is brazed with a PCD blade 3.
Specifically, the diameter of the transition tool bar 2 is smaller than the diameter of the fixed tool bar 1. The diameter of the supporting cutter bar 4 is smaller than that of the transition cutter bar 2.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
