Abstract
The utility model relates to the powder metallurgy field, especially relates to a cemented carbide blank of compound materials. The cemented carbide blank is frustum-shaped, and comprises a cemented carbide layer and a cemented carbide regeneration layer. The cemented carbide blank can be used as an integral cutter material. Under the premise of keeping the use performance of an integral cutter intact, the cemented carbide blank reduces material cost and saves resources. Moreover, the integral cutter is as good as an imported product of a same model.
Description
Technical field
The utility model relates to field of powder metallurgy, particularly a kind of carbide alloy blank of composite.
Background technology
Carbide alloy is to be raw material with rare metals such as tungsten, cobalts, through a kind of alloy material that powder metallurgy method obtains, has high strength, high rigidity and high temperature resistant, anti abrasive excellent material performance.The high-rate cutting carbide chip that is used for great type plant equipment processing, its size is all very thick usually big, to guarantee cutter enough rigidity and impact resistance is arranged.The carbide alloy blank is as cutter material; Also be fragile material simultaneously, receive the influence of powder metallurgy manufacturing process, carbide alloy blank grinding difficulty; When the impact of discontinuous cutting causes fritter fragmentation or wearing and tearing in using link; Monoblock carbide alloy blank all can be scrapped, and the carbide alloy blank waste that causes thus is very big, and processing cost is high.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of carbide alloy blank of composite is provided.
For realizing above-mentioned purpose, the utility model provides following technical scheme:
A kind of carbide alloy blank of composite, said blank are taper type, and the carbide alloy blank of said composite comprises hard alloy layer and carbide alloy regeneration zone.
In the carbide alloy blank of above-mentioned composite, said carbide alloy blank is three layers, and the upper and lower are hard alloy layer, and the intermediate layer is the carbide alloy regeneration zone.
In the carbide alloy blank of above-mentioned composite, said carbide alloy blank thickness is greater than 5mm.
In the carbide alloy blank of above-mentioned composite, said hard alloy layer is formed by former raw material.
In the carbide alloy blank of above-mentioned composite, said carbide alloy regeneration zone is formed by reworked material.
In the carbide alloy blank of above-mentioned composite, the quality raw materials of said former raw material for being produced according to traditional normal process technology.
In the carbide alloy blank of above-mentioned composite, said reworked material is for handling a kind of cheap raw material that scrap hard alloy obtains through special process.
In the carbide alloy blank of above-mentioned composite, said carbide alloy blank is that to contain tungsten, cobalt be main valuable alloy.
When the carbide alloy blank of the utility model composite was processed to hard alloy cutter, said hard alloy layer was as the key job position of cutter; The carbide alloy regeneration zone is as the non-key working position of cutter.
Compared with prior art, the beneficial effect of the utility model:The carbide alloy blank of the utility model composite is cutter material as a whole, is not changing under the solid tool serviceability condition, reaches to reduce material cost, aim of saving; And solid tool can compare favourably with the same model imported product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cutaway view of the utility model.
Mark among the figure: 1-hard alloy layer, 2-carbide alloy regeneration zone.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Shown in accompanying drawing 1, the carbide alloy blank of the composite of present embodiment is a taper type, and thickness is 6mm; Comprise hard alloy layer and carbide alloy regeneration zone; Said carbide alloy blank is three layers, and the upper and lower are hard alloy layer 1, and the intermediate layer is a carbide alloy regeneration zone 2.Hard alloy layer 1 is formed by former raw material, the quality raw materials of said former raw material for being produced according to traditional normal process technology; Carbide alloy regeneration zone 2 is formed by reworked material, and said reworked material is for handling a kind of cheap raw material that scrap hard alloy obtains through special process.The carbide alloy blank that makes this composite is cutter material as a whole; Under the solid tool serviceability condition after not changing processing; It is about 30～70% to save raw material, and it is about 10～40% to reduce the blade totle drilling cost, and the solid tool performance after the processing has no change.
Claims (3)
1. the carbide alloy blank of a composite, said blank is a taper type, it is characterized in that: said blank comprises hard alloy layer and carbide alloy regeneration zone.
