Abstract
The utility model discloses a PCD sharp cutter for machining the inner cone of a hard alloy pressed compact, which comprises a cutter base body and a cutter point part, wherein the cutter point part is in a triangular shape, a welding groove is arranged in the middle of the end part of the cutter point part, L-shaped clearance surfaces are arranged on two sides of the welding groove, the bottom of the welding groove is a positioning surface, a PCD blade is arranged on the positioning surface, and the outer side contour of the PCD blade is aligned with the outer side contour of the welding groove. The beneficial conditions of the utility model lie in: in the PCD blade embedded and the base member, more firmly durable, high rigidity PCD material processing carbide pressed compact effect is good, and the shaping of twolip design product is accurate, and it is easier than spark-erosion machining after the sintering in the carbide pressed compact stage processing, and production efficiency also promotes by a wide margin.
Description
Technical Field
The utility model relates to the field of hard alloy pressed compact processing equipment, in particular to a PCD (polycrystalline Diamond) sharp cutter for processing an inner cone of a hard alloy pressed compact.
Background
Carbide high pressure water jet nozzle products are typically provided with an internal cone at the nozzle inlet to provide water flow guidance. The traditional technology for processing the inner cone is to process a solid bar and then process the inner cone by an electric spark. Because the hardness of the hard alloy is very high, the electric spark machining speed is very slow, the production efficiency is low, and the cost is greatly increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model aims to provide a PCD (polycrystalline Diamond) sharp cutter for machining the inner cone of a hard alloy pressed compact, which has the advantages of high hardness and embedded cutter head, double-edge design, high machining efficiency and good forming effect.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
the utility model provides a PCD sharp sword that is used for interior awl processing of carbide pressed compact, includes cutter base member and sword point portion, sword point portion be three horn shapes, department is equipped with the welding groove in the middle of its tip, the welding groove both sides are equipped with the L type and keep away the face of empting, the bottom in welding groove is the locating surface, PCD blade is placed to locating surface department, PCD blade outside profile aligns with the welding groove outside profile.
Preferably, the substrate is made of tungsten steel, and the PCD blade is fixed in the welding groove through brazing.
Preferably, the nose portion is machined by a tool grinder to form two main cutting edges.
The beneficial conditions of the utility model are as follows: in the PCD blade embedded and the base member, more firmly durable, high rigidity PCD material cutting product effect is good, and twolip design product shaping is accurate, and it is easier than spark-erosion machining after the sintering in the carbide pressed compact stage processing, production efficiency also promotes by a wide margin.

Fig. 2 is a schematic view of the structure of the nose portion of the present invention.
FIG. 3 is a front view of an unspooled base of the present invention.
Fig. 4 is a left side view of the present invention without the blade base.
Detailed Description
As shown in figures 1, 2, 3, 4, a PCD sharp sword for processing of interior awl of carbide pressed compact, including cutter base member 1 and nose portion 2, nose portion 2 be the triangle-shaped, department is equipped with welding groove 3 in the middle of its tip, 3 both sides in welding groove are equipped with the L type and keep away empty face 4, the bottom in welding groove 3 is locating surface 5, PCD blade 6 is placed to 5 departments of locating surface, the outer profile of PCD blade 6 aligns with 3 outer profiles in welding groove. The basal body 1 is made of tungsten steel, and the PCD blade 6 is fixed in the welding groove 3 through brazing. The tool nose part 2 is processed by a tool grinder to form main cutting edges 7 on two sides. The PCD blade is embedded in the tool point part 2 of the tool base body 1, the PCD blade is fixed on the tool point part 2 in an up-and-down clamping mode through brazing, the PCD blade is firm and durable and is not easy to fall off, main cutting edges 7 with symmetrical two sides are formed through machining of a tool grinder, the forming effect is good, the machining speed is high, the L-shaped clearance surface 4 is formed, interference of the tool on a workpiece is reduced, and the rejection rate of products is reduced.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
