Abstract

The utility model discloses a reverse vacuum welding structure of minor diameter PCD cutter, including columniform cutter base member and the PCD complex piece that is located cutter base tip, the tip of cutter base member radially narrow, make the radius of its working member far be less than the radius of cutter base member, the tip welding of cutter base member have the PCD complex piece, the PCD complex piece adopt the vacuum welding mode to be connected with the cutter base member. Compare with leaning on compound piece alloy-layer welding mode of PCD, the utility model discloses the structure adopts vacuum welding, with PCD compound piece in PCD layer with the cutter body welding together, can grind the compound piece alloy-layer of PCD completely in order to reach the effect that the attenuate economizes the space.

Description

Reverse vacuum welding structure of minor diameter PCD cutter
Technical Field
The utility model belongs to the technical field of machining, concretely relates to reverse vacuum welding structure of minor diameter PCD cutter.
Background
Compared with a whole hard alloy cutter, the PCD cutter with the PCD composite sheet as a cutting edge is welded, and the PCD cutter has the advantages of high processing finish degree, longer service life and the like. However, since the PCD cutter needs to weld or otherwise fix the PCD compact on the steel cutter body or the alloy cutter body, the space is often limited to a certain extent, and the welding of the PCD cutter with a small diameter is particularly difficult.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, when guaranteeing welding strength, realize the welding of less diameter PCD cutter.
The utility model adopts the technical proposal that: the utility model provides a reverse vacuum welded structure of minor diameter PCD cutter, includes columniform cutter base member and the PCD compact that is located cutter base member tip, the tip of cutter base member radially narrow, make the radius of its working member far be less than the radius of cutter base member, the tip welding of cutter base member have the PCD compact, the PCD compact adopt the vacuum welding mode to be connected with the cutter base member.
The utility model discloses the beneficial effect who produces is: compare with leaning on compound piece alloy-layer welding mode of PCD, the utility model discloses the structure adopts vacuum welding, with PCD compound piece in PCD layer with the cutter body welding together, can grind the compound piece alloy-layer of PCD completely in order to reach the effect that the attenuate economizes the space.
Drawings
Fig. 1 is a radial view of the present invention;
fig. 2 is an axial view of the present invention;
fig. 3 is a schematic perspective view of the present invention;
in the figure: 1-PCD compact and 2-cutter substrate.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the utility model relates to a reverse vacuum welding structure of minor diameter PCD cutter, including columniform cutter base member and the compound piece 1 of PCD that is located cutter base member tip, the tip of cutter base member 2 radially narrow, make the radius of its working member far be less than the radius of cutter base member, the tip welding of cutter base member 2 have the compound piece of PCD, compound piece 1 of PCD adopt the vacuum welding mode to be connected with cutter base member 2, increased welding strength.
The traditional welding is generally only PCD composite sheet alloy-layer and blade contact surface for the welding contact surface, and the utility model discloses structure welding contact surface is two complete perpendiculars, welds more firmly and compares with the polycrystalline cutter of the whole polycrystalline material of welding, the utility model discloses the material cost and the processing cost of structure are lower.

Claims (1)

1. The utility model provides a reverse vacuum welding structure of minor diameter PCD cutter which characterized in that: the end part of the cutter substrate is radially narrowed, so that the radius of a working component of the cutter substrate is far smaller than that of the cutter substrate, the PCD compact is welded at the end part of the cutter substrate, and the welding contact surface of the PCD compact and the cutter substrate is two complete vertical surfaces; the PCD compact is connected with the cutter substrate in a vacuum welding mode.
