Problems solved by technology
However, it is more troublesome to replace the saw blade with a welded cutter head. It must be sent to a professional saw blade repair point or returned to the factory for tooth extraction and welding to replace a new cutter head. The cycle of changing the cutter head is long.
[0005] After the traditional circular saw blade is replaced with a new cutter head, the cutting edge must be reground, which is complicated and cumbersome.

The invention discloses a detachable cutting metal saw blade. The detachable cutting metal saw blade comprises a circular saw blade base body and detachable tool bits, the circular saw blade base body is provided with a center installation hole, sawteeth are arranged on the outer edge of the circular saw blade base body in the circumferential direction, tooth bottom chip containing grooves are formed in the positions, between the adjacent sawteeth, of the circular saw blade base body, the windward sides of the sawteeth are provided with tooth holders, and threaded holes are formed in the tooth bottom faces of the tooth holders; and positioning through holes are formed between the tip ends of the detachable tool bits and the bottom faces of the tool bits, the detachable tool bits are arranged on the tooth holders and detachably installed on the tooth holders through countersunk screws, and it is kept that cutting edges of the detachable tool bits face the cutting direction. The detachable cutting metal saw blade has the beneficial effects that the detachable tool bits and the circular saw blade base body can be detached and replaced at any time through the countersunk through holes and the threaded holes of the corresponding sizes under the connection of the countersunk screws, replacement of the detachable tool bits is facilitated, the replacement efficiency of the detachable tool bits is effectively improved, the replacement cost of the tool bits is reduced, the utilization rate of the base body is improved, and the overall service life of the saw blade is prolonged.
Description
technical field [0001] The invention relates to a detachable saw blade for cutting metal. Background technique [0002] Circular saw blades (including woodworking, aluminum alloy, ironwork cold saws, etc.) have always played an important role in the manufacturing industry, and are often used in the processing field. The more mature it is, the higher the end users' requirements for the quality and service life of circular saw blades are. Therefore, as a manufacturing enterprise, it is more and more important to improve the qualification rate of circular saw blades and the cutting service life of circular saw blades. [0003] Circular saw blades are generally composed of saw blade body and cutter head. The quality of the circular saw blade body, the sharpness and wear resistance of the cutter head play a decisive role in the use effect and final life of the saw blade. During the cutting process of the saw blade It is mainly the cutting action between the cutter head and the ...
