[0002] A saw blade is a tool accessory used to cut wood, metal or other materials. It is usually made of a thin piece of paper with a toothed edge. Saw blades come in different types and shapes, suitable for different types of work and materials. Common saw blades include hand saw blades, electric saw blades and circular saw blades.

[0004] However, when the first saw blade and the second saw blade are welded together in this patent, the positions of the first saw blade and the second saw blade may deviate.

[0005] Based on this, the utility model designs a low-pitched multi-layer saw blade to solve the above problems. Utility Model Content

[0009] It includes a first saw blade, a mounting hole, a second saw blade and a silencer. The front and rear ends of the silencer are respectively welded to the first saw blade and the second saw blade. The first saw blade, the second saw blade and the silencer are all provided with mounting holes at their centers. The first saw blade, the second saw blade and the silencer are all connected to a limiting assembly.

[0010] Furthermore, the first saw blade and the second saw blade have the same thickness.

[0011] Furthermore, the first saw blade, the second saw blade and the silencer are of the same size and are all circular.

[0012] Furthermore, the front and rear ends of the silencer are spot-welded to the first saw blade and the second saw blade respectively.

[0013] Furthermore, the total thickness of the first saw blade, the second saw blade and the silencer is 2.2 mm to 3.5 mm.

[0014] Furthermore, a wear-resistant coating is sprayed on the edges of the first saw blade and the second saw blade on the sides opposite to each other.

[0015] Furthermore, the limiting assembly includes a slot, a first protrusion and a second protrusion. The end of the first saw blade close to the silencer is fixedly connected with two symmetrically arranged first protrusions, and the end of the second saw blade close to the silencer is fixedly connected with two symmetrically arranged second protrusions, and the first protrusion and the second protrusion are staggered. Four slots are opened on the silencer at equal intervals along the circumference, and the first protrusion and the second protrusion are both plugged into the slots.

[0016] Furthermore, the silencer is made of a metal material that has good thermal conductivity and can absorb vibration.

[0017] Furthermore, the thickness of the first protrusion and the second protrusion is not greater than the thickness of the sound-absorbing plate.

[0018] Furthermore, the first protrusion and the second protrusion are square protrusions, and the slot is a square slot.

[0019] The utility model has the following technical effects:

[0020] When the utility model is installed, the silencer is placed on the second saw blade, and the second protrusion is inserted into the slot, and then the first saw blade is placed on the silencer, and the first protrusion is inserted into the remaining two slots, and finally the first saw blade, the second saw blade and the silencer are welded together by a spot welding machine;

[0021] When the utility model welds the first saw blade, the second saw blade and the silencer, the position of the first saw blade, the second saw blade and the silencer will not deviate;

[0022] The silencer of the utility model is made of a metal material with good thermal conductivity and vibration absorption, which can slow down the vibration of the saw blade during high-speed cutting and absorb the heat generated by the saw blade during high-speed cutting, thereby further reducing noise and accelerating heat dissipation. The saw blade has a thickness of 2.2mm to 3.5mm, which is more wear-resistant than a traditional single-piece saw blade, and will not have the problem of large resistance caused by excessive thickness of a traditional single-piece saw blade, thereby causing the saw blade to wear faster, generate heat, and thus shorten the life of the saw blade.
