Description
Technical Field
The utility model relates to a circular saw blade for cutting has especially related to a bimetallic material's circular saw blade.
Background
In the actual work of manufacturing industry, it is often necessary to cut materials such as plates, cast iron, glass, stone, plastics, etc. Circular saw blades (also known as "saw blades") are common tools used in cutting processes. The circular saw blade consists of a central base body and outer edge sawteeth, and the circular saw blade rotates at a high speed during working, and then the material is cut through the sawteeth positioned on the edge of the circular saw blade.
According to its metal material classification, the circular saw blade on the market at present has two kinds: the first type is a high-speed steel circular saw blade with the whole saw blade made of high-speed steel, and the saw blade has high integral hardness, good strength and long service life, but the whole saw blade is made of the high-speed steel, so the cost is high; the second type is an insert type circular saw blade in which teeth of one metal material are fastened to a base body of a second metal material by welding, and this type of saw blade requires welding of each tooth one by one although the cost of the metal material is reduced, and therefore, the manufacturing cost is also high.
Besides high cost, the two types of circular saw blades commonly found on the market have the defects of resource waste and environmental pollution: no matter the high-speed steel circular saw blade or the embedded-tooth type circular saw blade, after the saw tooth part is worn, the rest base body part material is difficult to reuse, and meanwhile, the basic part occupies most of the volume of the circular saw blade, so that two types of circular saw blades which are common in the market are used as consumable products for production, a large amount of resources are consumed, and meanwhile, the environment is polluted.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists among the background art, the utility model provides a bimetallic material's circular saw blade divide into two parts with original circular saw blade, this circular saw blade is low cost not only, saw cuts the performance moreover and is inferior to current product on the market, and this circular saw blade has base member material recycle's characteristics simultaneously to reducible loss to the resource, the environmental protection.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model discloses a circular saw blade includes the two parts of base member and high-speed steel band, and the base member is discoid, and high-speed steel band is the ring form, and is connected fixedly through the welding mode between high-speed steel band inward flange and the base member outward flange, and the outward flange of high-speed steel band sets up to the sawtooth.
The outer edge of the base body and the inner edge of the high-speed steel strip are both triangular tooth structures which are uniformly distributed along the circumference, and the triangular teeth of the base body and the inner edge of the high-speed steel strip are meshed with each other, so that the welding length between the base body and the high-speed steel strip is increased, and the welding strength is enhanced.
The substrate is made of metal materials.
The substrate is made of metal materials inconsistent with the high-speed steel strip.
The matrix occupies 85-95% of the whole circular saw blade area, and the high-speed steel strip occupies 5-15% of the whole circular saw blade area.
The circular saw blade is used for cutting materials.
The utility model has the advantages that:
1) the cost is low: the circular base body which accounts for 90 percent of the volume of the circular saw blade is made of common metal with low cost and moderate hardness, and only the circular ring which accounts for 10 percent of the volume of the circular saw blade is made of high-speed steel material with higher cost and higher hardness, so the overall cost of the whole saw blade can be greatly reduced;
2) the service life of the saw teeth is long: because the saw teeth are arranged on the high-speed steel circular ring, the hardness and the strength of the saw teeth are still consistent with those of the high-speed steel circular saw blade, and the working life consistent with that of the high-speed steel circular saw blade is further obtained;
3) and (3) recycling: after the working life is reached, only the circular ring needs to be cut off, and the central circular base body can be repeatedly used, so that the cost is reduced, and the environment is effectively protected.
Therefore, the utility model discloses can regard as the cutting tool of machines such as circular sawing machine, crowd's cutter, pipe cutting machine to use.
