Abstract
The utility model discloses a hard alloy-based reamer. The reamer comprises a handle part and a working part, wherein the working part is a machining section at the tail end of the handle part; a cutting edge is uniformly arranged at the front end of the machining section; a hard alloy cutting blade is embedded and welded on the cutting edge; and a hard coating is formed on the surface of the hard alloy cutting blade. The reamer has the advantages of reducing cost and greatly prolonging the service life of the reamer, along with simple structure and convenience of use.
Description
Technical field
The utility model relates to reamer, is specially a kind of reamer that adopts the carbide cutting sword.
Background technology
At present, in mechanical processing industry, new machining hole or the pre-hole of blank further added all will use reamer usually man-hour.Reamer is made up of shank and bar portion, and the gyratory directions of head evenly is provided with cutting edge.
The whole high-speed-steel structure that adopts of traditional reamer, the reamer of this structure in use can satisfy the requirement in factory, workshop substantially, meet the needs of production, but cost is too high, and the cutting edge part is not owing to strengthened, be easy to wearing and tearing, cause whole reamer discarded, do not meet and save the requirement that reduces discharging.
The utility model content
The technical problem that the utility model solved is to provide a kind of reamer based on carbide alloy, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of reamer based on carbide alloy, comprise shank and working portion, described shank can adopt high-speed steel or other steel cheaply, working portion is a processing sections of shank end, the front end of this processing sections evenly is provided with cutting edge, seting welding carbide cutting edge on the described cutting edge.
In the utility model, described carbide cutting sword surface coats hard coat, and this hard coat comprises titanium carbide, titanium nitride, aluminium oxide hard formation or the compound hard formation that adopts chemical vapour deposition technique to apply.
In the utility model, described carbide cutting sword is a plane on end face, when using this pre-hole of reamer processing blank, the gyratory directions of dependence processing sections is finished the function of hinge, if hinge blind hole, because the carbide cutting sword of end is a plane on gyratory directions, therefore can not form tapering in the bottom of blind hole.
Beneficial effect: the utility model is simple in structure, and is easy to use, not only lowered cost, and prolonged the service life of reamer greatly.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, a kind of reamer based on carbide alloy, comprise shank 1 and working portion 2, described shank 1 can adopt high-speed steel or other steel cheaply, working portion 2 is a processing sections of shank end, the front end of this processing sections evenly is provided with cutting edge, seting welding carbide cutting edge 3 on the described cutting edge.
In the present embodiment, described carbide cutting sword 3 surfaces coat hard coat, and this hard coat comprises titanium carbide, titanium nitride, aluminium oxide hard formation or the compound hard formation that adopts chemical vapour deposition technique to apply.
In the present embodiment, described carbide cutting sword 3 is a plane on end face, when using this pre-hole of reamer processing blank, the gyratory directions of dependence working portion 2 is finished the function of hinge, if hinge blind hole, because the carbide cutting sword 3 of end is a plane on gyratory directions, therefore can not form tapering in the bottom of blind hole.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. the reamer based on carbide alloy comprises shank and working portion, and described working portion is a processing sections of shank end, and the front end of this processing sections evenly is provided with cutting edge, it is characterized in that, seting welding carbide cutting edge on the described cutting edge.
2. a kind of reamer based on carbide alloy according to claim 1 is characterized in that, described carbide cutting sword surface coats hard coat.
