Abstract
The utility model relates to a sturdy and durable cutting tool. The sturdy and durable cutting tool comprises a tool body, wherein the edges of the tool body are evenly provided with tooth tables, cutter teeth are disposed on the tooth tables, and the angle of joints of roots of the cutter teeth and the tooth table is less than 90 degrees. According to the sturdy and durable cutting tool, the angle of the joints of the roots of the cutter teeth of the traditional cutting tool and the tooth tables is improved from 90 degrees into less than 90 degrees, and contact area of the cutter teeth and the tooth tables is increased so that fixing of the cutter teeth and the tooth tables can be stable. After the sturdy and durable cutting tool is used for a long time, even when the cutter teeth are abraded to be short, the contact area of the roots of the cutter teeth and the tooth tables is still large so that adhesive force big enough can still be supplied for the cutter teeth. Due to the facts that the contact area of the roots of the cutter teeth and the tooth tables is still large and the cutter teeth are still firmly fixed with the tooth tables, the falling phenomenon can not occur, the cutting tool can still be used normally, the service life of the cutting tool is prolonged, and utilization rate of the cutter teeth is high due to the fact the utilization rate of the cutter teeth is increased by more than 20%. Therefore, the sturdy and durable cutting tool has the advantages of being simple in structure, sturdy and durable, and long in service life.
Description
Technical field
The utility model relates to a kind of cutting tool, relates in particular to a kind of robust cutting tool of simple in structure, sturdy and durable, the long service life for cutting metal or nonmetal cutter sweep.
Background technology
Along with the high speed development of domestic housing construction and the raising of living standards of the people, wood-based plate particularly reinforced composite floorboard, furniture with low-density particleboard, and special fireproof plate for furniture developed rapidly.Above-mentioned sheet material all is that hardness is higher, processing difficulties, therefore in process, need with multiple cutter cutting and processing, and to having relatively high expectations of cutting performance, traditional cutting tool, as depicted in figs. 1 and 2, it comprises that edge is evenly arranged the cutter body 101 of tooth platform 102, cutter tooth 103 is set on the tooth platform 102, the angle 104 of the root of cutter tooth 103 and tooth platform 102 junctions is 90 °, like this along with cutter tooth 103 uses wearing and tearing for a long time, the contact area of the knife back of cutter tooth 103 and tooth platform 102 can be more and more less, because the root of cutter tooth 103 and the angle 104 of tooth platform 102 junctions are 90 °, the junction of the root of cutter tooth 103 and tooth platform 102 can not provide enough adhesive force for cutter tooth 103, cutter tooth 102 will come off in the incomplete situation of wearing and tearing like this, cause cutting-tool's used life very short, serious waste cutter tooth 102.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of robust cutting tool of simple in structure, sturdy and durable, the long service life for cutting metal or nonmetal cutter sweep is provided.
The purpose of this utility model is achieved in that a kind of robust cutting tool, comprises that edge is evenly arranged the cutter body of tooth platform, on the described tooth platform cutter tooth is set, and the angle of the root of cutter tooth and tooth platform junction is less than 90 °.
Described cutter body be by carbon constructional quality steel or the circular configuration made of structural alloy steel.
Described cutter tooth is the parallelogram shape structure that carbide alloy or diamond glomerocryst are made.
Described cutter tooth is fixed on the tooth platform by the mode of welding.
The utlity model has following good effect: the utility model is improved to the cutter tooth root of traditional cutting tool and the angle of tooth platform junction less than 90 ° by 90 °, increased the contact area of cutter tooth and tooth platform, make the fixing more firm of cutter tooth and tooth platform, after long-time the use, even cutter tooth may wear to very in short-term, the contact area of the root of cutter tooth and tooth platform is still larger, still can provide enough large adhesive force for cutter tooth, cutter tooth is also very firmly fixed with the tooth platform, the phenomenon that can not occur coming off, cutting tool can also normally use, so just prolonged the service life of cutting tool, make the utilization rate of cutter tooth higher, can improve the utilization rate of cutter tooth more than 20%, the utlity model has simple in structure, sturdy and durable, the advantage of long service life.

The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings:
Embodiment 1
As shown in Figure 3 and Figure 4, a kind of robust cutting tool comprises that edge is evenly arranged the cutter body 201 of tooth platform 202, on the described tooth platform 202 cutter tooth 203 is set, and the angle 204 of the root of cutter tooth 203 and tooth platform 202 junctions is less than 90 °.
The utility model is improved to the cutter tooth root of traditional cutting tool and the angle of tooth platform junction less than 90 ° by 90 °, increased the contact area of cutter tooth and tooth platform, make the fixing more firm of cutter tooth and tooth platform, after long-time the use, even cutter tooth may wear to very in short-term, the contact area of the root of cutter tooth and tooth platform is still larger, still can provide enough large adhesive force for cutter tooth, the contact area of the root of cutter tooth and tooth platform is still larger, cutter tooth is also very firmly fixed with the tooth platform, the phenomenon that can not occur coming off, cutting tool can also normally use, and has so just prolonged the service life of cutting tool, makes the utilization rate of cutter tooth higher, can improve the utilization rate of cutter tooth more than 20%, the utlity model has simple in structure, sturdy and durable, the advantage of long service life.
