Problems solved by technology

[0002] Existing reciprocating saw blades generally use high carbon steel (HCS), high speed steel (HSS) and bimetal (BIM), high carbon steel brazing carbide (HCS+HM) for wood, metal and wood plus nails, ceramic tiles Such cutting objects are mainly based on the inherent material characteristics and process performance characteristics of the material itself, and are manufactured into metal sawing products for different cutting modes and objects. They have certain shortcomings in terms of sawing performance and life, application range and cost performance. , and the classification of product specifications is complex and diverse, and the processing techniques are different

[0003] Application: high-carbon steel has good flexibility, but insufficient hardness and wear resistance, and is easy to saw off and become blunt; high-speed steel has good hardness and good wear resistance, but is not as soft and flexible as high-carbon steel, and is easily damaged by heat ;Bimetals take into account the advantages of the above two, but the cost performance of different modes is unreasonable. At the same time, there is room for improvement in tooth hardness, high thermal hardness, wear resistance, cutting speed and life; high carbon steel brazing hard alloy process is complex , and the application mode is single
