Abstract
The utility model discloses a kind of bimetallic brazed shank tool, comprise cutter head, handle of a knife, scolder, described cutter head material is carbide alloy, handle of a knife material is ordinary steel or high-quality high-carbon steel, it is characterized in that, the interface of described cutter head and handle of a knife is provided with a pylon, the interface of described handle of a knife and cutter head is provided with a recess, described recess is corresponding with described pylon shape, on all the other interfaces of described pylon and recess and cutter head and handle of a knife, have copper coating, described scolder is between the copper coating of cutter head and the copper coating of handle of a knife.On the solder side of the utility model due to cutter head and handle of a knife, there is copper coating, during soldering, the scolder of fusing easily with copper coating penetration, compatible, affine, the phenomenons such as the sand holes, hole, rosin joint of welding position have even been eradicated in minimizing, have avoided the generation of joint crackle.Due to firm welding, joint can not ftracture, therefore its long service life.
Description
Technical field
The utility model belongs to the cutter of using in machining, particularly a kind of bimetallic brazed shank tool.
Background technology
Bimetallic brazed shank tool is that carbide bit becomes as a whole cutter with ordinary steel or high-quality high-carbon steel handle of a knife by soldering.Because the material of cutter head and handle of a knife is different, both expansion coefficient differences are larger, and solder flux is different to the infiltration degree of welding position, therefore, directly with solder flux, both welding are not only difficult for, and there are sand holes that degree is different, hole, rosin joint etc. in welding position, even also can produce joint crackle.In a word, current bimetallic brazed shank tool always exists not prison welding solid, and joint is the defect of cracking easily.
Summary of the invention
The purpose of this utility model is to propose a kind of firm welding, the bimetallic brazed shank tool that joint can not ftracture.
The technical scheme that realizes above-mentioned purpose is: a kind of bimetallic brazed shank tool, comprise cutter head, handle of a knife, scolder, described cutter head material is carbide alloy, handle of a knife material is ordinary steel or high-quality high-carbon steel, it is characterized in that, the interface of described cutter head and handle of a knife is provided with a pylon, the interface of described handle of a knife and cutter head is provided with a recess, described recess is corresponding with described pylon shape, on all the other interfaces of described pylon and recess and cutter head and handle of a knife, have copper coating, described scolder is between the copper coating of cutter head and the copper coating of handle of a knife.
Described copper coating is brass coating.
The thickness of described brass coating is 0.008～0.02mm.
Described scolder is strong solder.
Described strong solder thickness is 0.05～0.2mm.
Total institute is known, and no matter metal solder is the metal solder of identical material or the metal solder of unlike material, conventionally all adopts spelter solder to carry out soldering.In the utility model, owing to having layer of copper coating on the cutter head of carbide alloy and the solder side of ordinary steel or high-quality high-carbon steel handle of a knife, this copper coating is identical with the composition of scolder, like this when soldering, the scolder of fusing easily and copper coating penetration, compatible, affine, the faying face of full two weldments of profit, scolder can be full of weld gap, reduce the phenomenons such as the sand holes even eradicated welding position, hole, rosin joint, and weld interval can be shortened, the stress that reduces metal inside, welding residual deformation is little, has avoided the generation of joint crackle.The utility model is due to firm welding, and joint can not ftracture, therefore its long service life.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of an embodiment of the utility model.
Fig. 2 is the broken away view of cutterhead and handle of a knife in Fig. 1.
Fig. 3 is I portion enlarged drawing in Fig. 1.
In figure: 1. cutter head, 2. handle of a knife, 3. pylon, 4. recess, 5. scolder, 6. copper coating.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, the utility model comprises cutter head 1, handle of a knife 2, scolder 5, the material of cutter head 1 is carbide alloy, the material of handle of a knife 2 is ordinary steel or high-quality high-carbon steel, it is characterized in that, on the solder side of cutter head 1, the interface that is itself and handle of a knife 2 is provided with a pylon 3, on the solder side of handle of a knife 2, the interface that is itself and cutter head 1 is provided with a recess 4, recess 4 is corresponding with the shape of pylon 3, on all the other interfaces of pylon 3 and recess 4 and cutter head 1 and handle of a knife 2, has copper coating 6, and scolder 5 is between the copper coating 6 of cutter head 1 and the copper coating 6 of handle of a knife 2.
In the present embodiment, copper coating 6 is brass coating, and the thickness of brass coating is 0.008～0.02mm; Scolder 5 is strong solder, and the thickness of strong solder is 0.05～0.2mm, and this thickness is also weld gap.
Claims (5)
